Among these communication modules, a corresponding communication module may communicate with an external electronic device (104) via a first network (198) (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct, or infrared data association (IrDA)) or a second network (199) (e.g., a long-range communication network such as a legacy cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (e.g., a LAN or WAN)). These various types of communication modules may be integrated into a single component (e.g., a single chip) or implemented as multiple separate components (e.g., multiple chips).

The wireless communication module (192) can support a 5G network and next-generation communication technology after a 4G network, for example, NR access technology (new radio access technology). The NR access technology can support high-speed transmission of high-capacity data (eMBB (enhanced mobile broadband)), terminal power minimization and connection of multiple terminals (mMTC (massive machine type communications)), or high reliability and low latency (URLLC (ultra-reliable and low-latency communications)). The wireless communication module (192) can support, for example, a high-frequency band (e.g., mmWave band) to achieve a high data transmission rate. The wireless communication module (192) may support various technologies for securing performance in a high-frequency band, such as beamforming, massive multiple-input and multiple-output (MIMO), full dimensional MIMO (FD-MIMO), array antenna, analog beam-forming, or large scale antenna.

At least some of the above components may be interconnected and exchange signals (e.g., commands or data) with each other via a communication method between peripheral devices (e.g., a bus, a general purpose input and output (GPIO), a serial peripheral interface (SPI), or a mobile industry processor interface (MIPI)).

In one embodiment, commands or data may be transmitted or received between the electronic device (101) and an external electronic device (104) via a server (108) connected to a second network (199). Each of the external electronic devices (102, or 104) may be the same or a different type of device as the electronic device (101). In one embodiment, all or part of the operations executed in the electronic device (101) may be executed in one or more of the external electronic devices (102, 104, or 108). For example, when the electronic device (101) is to perform a certain function or service automatically or in response to a request from a user or another device, the electronic device (101) may, instead of executing the function or service itself or in addition, request one or more external electronic devices to perform at least a part of the function or service. One or more external electronic devices that have received the request may execute at least a part of the requested function or service, or an additional function or service related to the request, and transmit the result of the execution to the electronic device (101). The electronic device (101) may process the result as it is or additionally and provide it as at least a part of a response to the request. For this purpose, for example, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technology may be used.

FIG. 2 is a drawing showing an example of a configuration of a software module of an electronic device according to one embodiment;

Referring to FIGS. 1 and 2, an electronic device (101) according to one embodiment (e.g., the electronic device (101) of FIG. 1) may implement a software module (201) (e.g., the program (140) of FIG. 1) for executing brightness control of a display (e.g., the display module (160) of FIG. 1). A memory (130) of the electronic device (101) may store commands (e.g., instructions) to implement the software module (201) illustrated in FIG. 2. At least one processor (120) may execute the commands stored in the memory (130) to implement the software module (201) illustrated in FIG. 2, and control hardware (e.g., the sensor module (176), the power management module (188) of FIG. 1, the display module (160) or other necessary components) associated with a function of the software module (201).

A software module (201) of an electronic device (101) according to one embodiment may be configured to include a kernel (or a hardware abstraction layer (HAL)) (210), a framework (e.g., a middleware (144) of FIG. 1) (220), and an application (230) (e.g., an application (146) of FIG. 1). At least a part of the software module (201) may be preloaded on the electronic device (101) or may be downloadable from a server (e.g., a server (108)).

According to one embodiment, the kernel (210) may be configured to include, for example, a display driver (211).

The device driver may include, for example, a camera driver, a Bluetooth driver, a shared memory driver, a USB driver, a keypad driver, a WIFI driver, an audio driver, an IPC (inter-process communication) driver, or other device drivers.

According to one embodiment, the framework (220) may include, for example, a display management service (221) and a power management service (223), but is not limited thereto and may be configured to further include other modules (or services). The framework (220) may provide functions commonly required by the application (230) or provide various functions to the application (230) through an application programming interface (API) (not shown) so that the application (230) can efficiently use limited system resources within the electronic device (101). The display management service (211) may provide a function according to the driving of the display. The power management service (223) may transfer the first brightness control value set by the processor (120) to the display driver (211) so as to change the brightness of the display to the first brightness control value, which is a relatively large brightness control value (e.g., the maximum value) under the control of the processor (120). The power management service (223) can manage a battery or power, provide power information necessary for the operation of an electronic device, and provide a function for checking current consumption according to heat control. The framework (220) can include a module that forms a combination of various functions of the aforementioned components. The framework (220) can provide a module specialized for each type of operating system in order to provide differentiated functions. The framework (220) can dynamically delete some of the existing components or add new components.

At least a portion of the software module (201) may be implemented (e.g., executed) by, for example, a processor (e.g., an AP). At least a portion of the software module (201) may include, for example, at least one of a module, a program, a routine, a set of instructions, or a process for performing at least one function.

FIGS. 3A, 3B, and 3C are diagrams showing brightness control information in an electronic device according to one embodiment.

Referring to FIGS. 1, 2, 3A, 3B, and 3C, according to one embodiment, the processor (120) of an electronic device (e.g., the electronic device (101) of FIGS. 1 and 2) may obtain a surface temperature value of the electronic device (101) by using at least one temperature sensor included in a sensor module (176). According to one embodiment, the external temperature of the electronic device (101) may be obtained by using at least one temperature sensor included in the sensor module (176), and the illuminance value (e.g., a brightness value) may be obtained by detecting external light (e.g., direct sunlight) by using at least one illuminance sensor included in the sensor module (176). Here, the surface temperature value may be obtained through machine learning by learning an actual surface temperature detected in an area of a housing of the electronic device (101) by using at least one temperature sensor. The external temperature value can utilize the difference in temperature difference value between the sensors for measuring the internal temperature of the electronic device (101) depending on the outside temperature, and can be acquired (e.g., estimated or calculated) by the electronic device (101) based on the temperature difference value by using a formula modeling technique, machine learning, or a temperature table stored in advance in the memory (130). There is no limitation on the method of acquiring the surface temperature value and the external temperature value. The external temperature value may be different from the actual temperature value of the external environment surrounding the electronic device (101). The processor (120) can acquire the surface temperature value by alternatively or supplementarily utilizing the internal temperature of the electronic device (101). Here, the internal temperature can be acquired by utilizing the temperature change detected by a temperature sensor (e.g., a thermistor) adjacent to a module of the electronic device (101) that is not related to heat generation and the time required for the temperature change.

According to one embodiment, the processor (120) may determine that the brightness of the display (e.g., the display module (160) of FIG. 1) needs to be controlled to a relatively high brightness (e.g., maximum brightness) due to a temperature rise of the electronic device (101) caused by an external influence based on the surface temperature value being equal to or higher than the reference temperature (Tc) (e.g., 38 degrees (℃) of FIGS. 3a, 3b, and 3c), and may store the acquired surface temperature (Ts) value. According to one embodiment, the processor (120) may acquire a designated brightness control value (e.g., a set value) corresponding to an external temperature value and/or an illuminance value from brightness control information (e.g., the first brightness control information of FIG. 3a, the second brightness control information of FIG. 3b, or the third brightness control information of FIG. 3c), and may set the acquired brightness control value as the first brightness control value (e.g., the maximum brightness control value) of the display. Here, the brightness control value (e.g., set value) included in the brightness control information can be set in response to a specified external temperature level and/or a specified illuminance level. The brightness control information can be preset in a table form and stored in a memory (e.g., memory (130) of FIG. 1).

According to one embodiment, the processor (120) can change the brightness of the display to increase the visibility of the display based on the set first brightness control value.

According to one embodiment, when the processor (120) does not set the brightness of the display to the first brightness control value, the processor (120) may set the brightness of the display to a designated brightness control value corresponding to an external temperature value and/or illuminance value obtained using basic brightness control information (e.g., the second brightness control information of FIG. 3b).

According to one embodiment, the processor (120) may pre-designate and store in the memory (130) first brightness control information and second brightness control information for setting a relatively large brightness control value (e.g., a maximum brightness control value) as the first control brightness value, as illustrated in FIGS. 3A and 3B .

Referring to FIG. 3A, the first brightness control information according to one embodiment may include brightness control values (e.g., setting values) for changing or setting the first brightness control value (e.g., maximum brightness control value, brightness policy) based on an external temperature value and/or an illuminance value. The basic brightness control values (400, 300, 200, 150) (e.g., basic setting values) of the first brightness control information of FIG. 3A may be set (e.g., designated) in response to each of the external temperature levels and each of the designated surface temperature levels based on a reference illuminance level (e.g., 3000 lux ↓ or 3000 lux or less). The first brightness control information may not set a brightness control value in response to a first reference surface temperature level (e.g., 38 degrees or 38 degrees or less) so as not to change the first brightness control value (e.g., no limitation). Here, the specified surface temperature levels can include a first surface temperature level (e.g., 40 degrees (or a temperature value in a range from greater than 38 degrees to less than 40 degrees)), a second surface temperature level (e.g., 42 degrees (or a temperature value in a range from greater than 40 degrees to less than 42 degrees)), a third surface temperature level (e.g., 45 degrees (or a temperature value in a range from greater than 42 degrees to less than 45 degrees)), a second reference surface temperature level (e.g., 47 degrees or greater than or equal to 47 degrees)). Here, the external temperature levels can include a first external temperature level (e.g., a first external temperature level (e.g., 30 degrees (or a temperature value in a range from greater than 25 degrees to less than 30 degrees)), a second external temperature level (e.g., 35 degrees (or a temperature value in a range from greater than 30 degrees to less than 35 degrees)).

Referring to FIG. 3b, the second brightness control information according to one embodiment may include default brightness control values (e.g., default setting values) for changing or setting a relatively large brightness control value (e.g., maximum brightness control value, brightness policy) as a first brightness control value based on an external temperature value and/or illuminance value. The basic brightness control values (e.g., 400, 300, 200, 150) of the second brightness control information of FIG. 3b may be set (e.g., specified) in response to a reference external temperature (e.g., 25 degrees or less than or equal to 25 degrees), a specified first surface temperature level (e.g., 40 degrees (or a temperature value in a range from more than 38 degrees to less than or equal to 40 degrees), a specified second surface temperature level (e.g., 47 degrees or more than 45 degrees to less than or equal to 47 degrees), and a reference illuminance level (e.g., an illuminance value less than or equal to 3000 lux), a first illuminance level (e.g., an illuminance value greater than 3000 lux or a illuminance value greater than 3000 lux to less than or equal to 10000 lux) and/or a second illuminance level (e.g., an illuminance value greater than 10000 lux or a illuminance value greater than 10000 lux).

The brightness control value may not be set (e.g., specified) so as not to change the first brightness control value (e.g., no limit) in response to a temperature of 38 degrees or less.

Referring to FIG. 3c, according to one embodiment, the processor (120) may pre-designate third brightness control information for setting the first brightness control value and store it in the memory (130). According to one embodiment, the processor (120) may correspond to the first illuminance level at a specific external temperature (e.g., a temperature value within a range from 30 degrees or 25 degrees to 30 degrees or less) and a second reference temperature (e.g., less than 47 degrees) in the third brightness control information, and may set the designated brightness control values (e.g., set values) corresponding to each of the designated surface temperature levels to be higher by a designated first ratio (e.g., 25% compared to the reference illuminance level of FIG. 3c). In one embodiment, the electronic device may correspond to a second illuminance level at a specific external temperature (e.g., a temperature value within a range of 30 degrees or 25 degrees to 30 degrees) and less than a second reference temperature (e.g., less than 47 degrees) in the third brightness control information, and may set the designated brightness control values (e.g., set values) to be higher by a designated second ratio (e.g., 50% relative to the reference illuminance level of FIG. 3C) corresponding to each of the designated surface temperature levels. Here, the third brightness control information may be set to a higher ratio (e.g., a constant ratio specified through an experiment or by a user) than the default brightness control values (e.g., 40 degrees (or a temperature value in a range from 38 degrees to 40 degrees) and 47 degrees or 45 degrees to 47 degrees)) of the reference illuminance level (e.g., 3000 lux ↓ or 3000 lux or less) or the default brightness control values (e.g., 400, 300, 200, and 150) included in the second brightness control information of FIG. 3b, corresponding to the temperature levels (e.g., a temperature value in a range from 38 degrees to 40 degrees) and the specified second surface temperature level (e.g., 47 degrees or 45 degrees to 47 degrees or less)).

The external temperature levels and surface temperature levels specified in the first to third brightness information illustrated in FIGS. 3A to 3C can each be pre-specified through experiments, and can be set to other values or ranges than the levels set in FIG. 3A depending on at least one of the device type, usage environment (e.g., outdoors, indoors, weather, or usage time), or factors related to heat generation (e.g., usage application).

According to one embodiment, the processor (120) may set a first brightness control value to a brightness control value (e.g., a set value) included in first brightness control information corresponding to the surface temperature value and the external temperature value, based on the surface temperature value being equal to or greater than a reference temperature (Tc) level and the external temperature value exceeding the reference external temperature level. For example, as illustrated in FIG. 3A, if the processor (120) determines that the acquired surface temperature value of the electronic device is a first surface temperature level (e.g., a temperature value in the range of 40 degrees or more than 38 degrees and less than or equal to 40 degrees) that exceeds a first reference temperature level (e.g., 38 degrees) and the acquired external temperature value is a first external temperature level (e.g., a temperature value in the range of 30 degrees or more than 25 degrees and less than or equal to 30 degrees) that is greater than a reference external temperature level (e.g., 25 degrees), the processor (120) may acquire a brightness control value (e.g., a brightness value of 600 nt or 800 nt) specified in response to the first surface temperature level and the first external temperature level, and set the first brightness control value to the acquired brightness control value (e.g., 600 nt or 800 nt). For example, as illustrated in FIG. 3A, if the processor (120) determines that the acquired surface temperature value of the electronic device (101) is a first surface temperature level (e.g., a temperature value of 40 degrees or more than 38 degrees but less than or equal to 40 degrees) that exceeds a first reference temperature level (e.g., 38 degrees) and the acquired illuminance value is a first illuminance level (e.g., an illuminance value in the range of ↑3000 lux or more than 3000 lux but less than or equal to 10000 lux) that is greater than a reference illuminance level (e.g., 3000 lux), the processor (120) may acquire a brightness control value (e.g., a brightness value of 600 nt) specified in response to the first surface temperature level and the first illuminance level, and set the first brightness control value to the acquired brightness control value (e.g., 600 nt).

According to one embodiment, the processor (120) may set the brightness of the display to a default brightness control value (e.g., a default setting value) included in the second brightness control information corresponding to the surface temperature value and the external temperature value based on the surface temperature value being equal to or higher than a reference temperature (Tc) level and the external temperature value being equal to or lower than the reference external temperature. For example, as illustrated in FIG. 3B , if the processor (120) determines that the acquired surface temperature value of the electronic device (101) is a first surface temperature level (e.g., a temperature value of 40 degrees or greater than 38 degrees but less than or equal to 40 degrees) exceeding a first reference temperature level (e.g., 38 degrees) and the acquired external temperature value is equal to or lower than the reference external temperature level (e.g., 25 degrees), the processor (120) may acquire a brightness control value (e.g., a luminance value of 400 nt) specified in response to the first surface temperature level and the reference external temperature level, and set the first brightness control value to the acquired brightness control value (e.g., 400 nt). For example, as illustrated in FIGS. 3A and 3B , when the processor (120) determines that the acquired surface temperature value of the electronic device (101) is a first surface temperature level (e.g., a temperature value of 40 degrees or more than 38 degrees but less than or equal to 40 degrees) exceeding a first reference temperature level (e.g., 38 degrees) and the acquired illuminance value is less than or equal to a reference illuminance level (e.g., 3000 lux), the processor (120) may acquire a brightness control value (e.g., a luminance value of 400 nt) designated in response to the first surface temperature level and the reference illuminance level, and set the first brightness control value to the acquired brightness control value (e.g., 400 nt).

According to one embodiment, the processor (120) may change the brightness of the display to the set first brightness control value if the first brightness control value is less than the current brightness value, and may not change the brightness of the display to the first brightness control value if the first brightness control value is not less than the current brightness value.

According to one embodiment, the processor (120) may set the first brightness control value based on all of the surface temperature, the external temperature value, and the illuminance value. For example, as illustrated in FIG. 3A, if the electronic device determines that the acquired surface temperature value is a first surface temperature level (e.g., a temperature value in a range from 40 degrees or more than 38 degrees to 40 degrees or less) that exceeds a first reference temperature level (e.g., 38 degrees), the acquired external temperature value is a first external temperature level (e.g., a temperature value in a range from 30 degrees or more than 25 degrees to 30 degrees or less) that exceeds a reference external temperature level (e.g., 25 degrees), and the illuminance value is a first illuminance level (e.g., an illuminance value in a range from more than 3000 lux to less than 10000 lux), the electronic device may acquire a brightness control value (e.g., a luminance value of 600 nt) specified in response to the first surface temperature level, the first external temperature level, and the first illuminance level, and set the first brightness control value to the acquired brightness control value (e.g., 600 nt).

According to one embodiment, the processor (120) may acquire a brightness control value (e.g., a set value) specified in third brightness information corresponding to the acquired surface temperature value and the external temperature value and/or the illuminance value, and set a first brightness control value to the acquired brightness control value. For example, if the acquired external temperature value is a specific temperature level (e.g., a range of 30 degrees or more than 25 degrees to less than 30 degrees) and a first surface temperature level (e.g., a range of 40 degrees or more than 38 degrees to less than 40 degrees) set corresponding to a second illuminance level (e.g., a range of 3000 lux to less than 10000 lux) below a second reference temperature, the processor (120) may set a brightness control value (e.g., 500 nt) that is specified to be higher by a first ratio (e.g., 25%) than the basic brightness control value in response to the second illuminance level and the first surface temperature level as the first brightness control value.

In one embodiment, the processor (120) may be configured not to change or set the brightness of the display to the first brightness control value based on the acquired surface temperature value being below a reference temperature level.

As such, in one embodiment, the main components of the electronic device have been described through the electronic device (101) of FIGS. 1 and 2. However, in various embodiments, not all of the components illustrated through FIGS. 1 and 2 are essential components, and the electronic device (101) may be implemented with more components than the illustrated components, or may be implemented with fewer components.

FIG. 4 is a drawing showing an example of an operating method in an electronic device according to one embodiment.

Referring to FIG. 4, in operation 401, an electronic device (e.g., the electronic device (101) of FIGS. 1 and 2) according to an embodiment of the present invention, a processor (120) may obtain a surface temperature value of the electronic device by using at least one temperature sensor included in a sensor module (e.g., the sensor module (176) of FIG. 1). The electronic device may obtain an external temperature of the electronic device by using at least one temperature sensor included in the sensor module, and may detect external light (e.g., direct sunlight) by using at least one illuminance sensor to obtain an illuminance value (e.g., a brightness value). Here, the surface temperature value may be obtained through machine learning by learning an actual surface temperature detected in an area of a housing of the electronic device by using at least one temperature sensor. The external temperature value may utilize a difference in temperature difference values between sensors for measuring the internal temperature of the electronic device, and may be estimated by using a mathematical modeling technique, machine learning, or a temperature table stored in a memory based on the temperature difference values. There is no limitation on a method for measuring the surface temperature value and the external temperature. Surface temperature values can be obtained by alternative or complementary use of the internal temperature.

In operation 403, the electronic device according to one embodiment can check whether the surface temperature value is equal to or higher than the reference temperature (Tc). If the surface temperature value is equal to or higher than the reference temperature (operation 403 - Yes), the electronic device can perform operation 405, and if the surface temperature value is not equal to or higher than the reference temperature (operation 403 - No), the electronic device can perform operation 401.

In operation 405, the electronic device according to one embodiment determines that it is necessary to control the brightness of a display (e.g., display module (160) of FIG. 1) to a relatively high brightness (e.g., maximum brightness) due to a temperature rise of the electronic device caused by an external influence, based on the surface temperature value being equal to or higher than a reference temperature (Tc) level, and stores the acquired surface temperature (Ts) value.

In operation 407, the electronic device according to one embodiment may set a relatively large brightness control value (e.g., a maximum brightness control value) as a first brightness control value for changing the brightness of the display to the maximum based on the acquired external temperature value or the acquired illuminance value. The electronic device may acquire a designated brightness control value corresponding to the external temperature value and/or the illuminance value from brightness control information (e.g., the first brightness control information of FIG. 3A, the second brightness control information of FIG. 3B, or the third brightness control information of FIG. 3C), and set the acquired brightness control value as the first brightness control value of the display. Here, the brightness control value included in the brightness control information may be set corresponding to a designated external temperature level and/or a designated illuminance level. The brightness control information may be preset in a table form and stored in a memory (e.g., the memory (130) of FIG. 1).

In operation 409, the electronic device according to one embodiment can change the brightness of the display based on the first brightness control value.

In one embodiment, the electronic device may set the brightness of the display to a designated brightness control value corresponding to an external temperature value and/or illuminance value obtained using basic brightness control information (e.g., second brightness control information) when the brightness of the display is not set to the first brightness control value.

FIG. 5 is a drawing showing an example of an operating method in an electronic device according to one embodiment.

Referring to FIG. 5, in operation 501, an electronic device (e.g., the electronic device (101) of FIGS. 1 and 2, processor (120)) according to an embodiment may obtain a surface temperature value of the electronic device by using at least one temperature sensor included in a sensor module (e.g., the sensor module (176) of FIG. 1). The electronic device may obtain (e.g., estimate or calculate) an external temperature value and detect external light (e.g., direct sunlight) by using at least one illuminance sensor included in the sensor module to obtain an illuminance value. Here, the surface temperature value may be obtained through machine learning by learning an actual surface temperature detected in an area of a housing of the electronic device by using at least one temperature sensor. The external temperature value may be obtained (e.g., estimate or calculate) by using a formula modeling technique, machine learning, or a temperature table stored in a memory based on a temperature difference value between sensors for measuring an internal temperature of the electronic device (101). The surface temperature value may be obtained by using the internal temperature as a substitute or supplementary measure.

In operation 503, the electronic device according to one embodiment can check whether the surface temperature value is equal to or higher than the reference temperature (Tc). If the determination result shows that the surface temperature value is equal to or higher than the reference temperature level (operation 503 - Yes), the electronic device can perform operation 505, and if the surface temperature value is not equal to or higher than the reference temperature level (operation 503 - No), the electronic device can perform operation 501. If the acquired surface temperature value is equal to or lower than the first reference temperature level (e.g., 38 degrees, which is the first reference temperature level of FIGS. 3A to 3C ), the electronic device can maintain the currently set brightness (e.g., brightness automatically set according to the application or usage environment or manually set by the user) without changing the display brightness (e.g., no limitation). If the acquired surface temperature value is equal to or higher than a specific temperature (e.g., 47 degrees, which is the second reference temperature level of FIGS. 3A to 3C ), the electronic device can set the display brightness to a brightness control value (e.g., 150nt) that is equally specified for all illuminance levels without changing the display brightness to the maximum.

In operation 505, an electronic device according to one embodiment may determine that it is necessary to control the brightness of a display (e.g., a display module (160) of FIG. 1) to a relatively high brightness (e.g., maximum brightness) due to a temperature rise of the electronic device caused by an external influence, and may store the acquired surface temperature (Ts) value.

In operation 507, the electronic device according to one embodiment can determine whether the illuminance value exceeds a reference illuminance level. If the illuminance value exceeds the reference illuminance level, the electronic device can perform operation 509, and if the illuminance value is less than or equal to the reference illuminance level, the electronic device can perform operation 511.

In operation 509 (operation 507-Example), the electronic device according to one embodiment may set a relatively large brightness control value (e.g., a maximum brightness control value) as a first brightness control value based on the first brightness control information. The electronic device may obtain a brightness control value (e.g., a set value) included in the first brightness control information in response to the obtained illuminance value, and set the obtained brightness control value as the first brightness control value. For example, if the electronic device determines that the acquired surface temperature value of the electronic device is a first surface temperature level (e.g., a temperature value of 40 degrees or more than 38 degrees and less than or equal to 40 degrees) exceeding a first reference temperature level (e.g., 38 degrees) and the acquired illuminance value is a first illuminance level (e.g., an illuminance value in a range of more than 3000 lux and less than or equal to 10000 lux) greater than the first reference illuminance level (e.g., 3000 lux), as illustrated in FIG. 3A, the electronic device may acquire a brightness control value (e.g., a brightness value of 600 nt) specified in response to the first surface temperature level and the first illuminance level, and set the first brightness control value to the acquired brightness control value (e.g., 600 nt). The illuminance levels and surface temperature levels specified in the first brightness control information can each be pre-specified through experiments, and can be set to other values or ranges than the levels or ranges set in FIG. 3a depending on at least one of the device type, the usage environment (e.g., outdoors, indoors, weather, or usage time), or factors related to heat generation (e.g., usage application). When performing the 509 operation, the external temperature may not be considered or may be determined to be lower than or equal to a reference external temperature level (e.g., 25 degrees).

In operation 511 (operation 507-No), the electronic device according to one embodiment may set the first brightness control value based on the second brightness control information. The electronic device may acquire a brightness control value (e.g., a set value) included in the second brightness control information in response to the acquired illuminance value, and set the first brightness control value with the acquired brightness control value. For example, as illustrated in FIGS. 3A and 3B , if the acquired surface temperature value of the electronic device is a first surface temperature level (e.g., a temperature value exceeding 40 degrees or 38 degrees to 40 degrees or less) exceeding a first reference temperature level (e.g., 38 degrees) and the acquired illuminance value is lower than or equal to a reference illuminance level (e.g., 3000 lux), the electronic device may acquire a brightness control value (e.g., a luminance value of 400 nt) specified in response to the first surface temperature level and the reference illuminance level, and set the first brightness control value with the acquired brightness control value (e.g., 400 nt). The illuminance levels and surface temperature levels specified in the second brightness control information can each be pre-specified through experiments, and can be set to other values or ranges than the levels or ranges set in FIG. 3b depending on at least one of the device type, the usage environment (e.g., outdoors, indoors, weather, or usage time), or factors related to heat generation (e.g., usage application). When performing the 511 operation, the external temperature may not be considered or may be determined to be lower than or equal to a reference external temperature level (e.g., 25 degrees).

In operation 513, the electronic device according to one embodiment can check whether the first brightness control value is less than the current brightness value. If the check result shows that the set brightness control value is less than the current brightness value (operation 513 - Yes), the electronic device can perform operation 515, and if not (operation 513 - No), the electronic device can perform operation 501.

In one embodiment of the invention, an electronic device may change the brightness of a display to a set brightness control value.

FIG. 6 is a drawing showing an example of an operating method in an electronic device according to one embodiment.

Referring to FIG. 6, in operation 601, an electronic device (e.g., the electronic device (101) of FIGS. 1 and 2, processor (120)) according to an embodiment may obtain a surface temperature value of the electronic device by using at least one temperature sensor included in a sensor module (e.g., the sensor module (176) of FIG. 1). The electronic device may obtain (e.g., estimate or calculate) an external temperature value and detect external light (e.g., direct sunlight) by using at least one illuminance sensor included in the sensor module to obtain an illuminance value. Here, the surface temperature value may be obtained through machine learning by learning an actual surface temperature detected in an area of a housing of the electronic device by using at least one temperature sensor. The external temperature value may be obtained (e.g., estimate or calculate) by using a temperature difference value between sensors for measuring an internal temperature of the electronic device (101), a machine learning formula modeling technique, or a temperature table stored in a memory. There is no limitation on the method of obtaining the surface temperature value and the external temperature value. Surface temperature values can be obtained by alternative or complementary use of the internal temperature.

In operation 603, the electronic device according to one embodiment may check whether the surface temperature value is equal to or higher than a reference temperature (Tc) level (e.g., a reference surface temperature). If the surface temperature value is equal to or higher than the reference temperature level (operation 603-Yes), the electronic device may perform operation 605, and if the surface temperature value is not equal to or higher than the reference temperature level (operation 603-No), the electronic device may perform operation 601. If the acquired surface temperature value is equal to or lower than the first reference temperature level (e.g., 38 degrees, which is the first reference temperature level of FIGS. 3A to 3C), the electronic device may maintain the currently set brightness (e.g., brightness automatically set according to an application or usage environment or manually set by a user) without changing the display brightness (e.g., no limitation). The electronic device can set the display brightness to a brightness control value (e.g., 150nt) that is equally designated for all illuminance levels without changing the display brightness to maximum if the acquired surface temperature value is above a specific temperature (e.g., 47 degrees, which is the second reference temperature level of FIGS. 3A to 3C).

In operation 605, an electronic device according to one embodiment may determine that it is necessary to control the brightness of a display (e.g., a display module (160) of FIG. 1) to a relatively high brightness (e.g., maximum brightness) due to a temperature rise of the electronic device caused by an external influence, and may store the acquired surface temperature (Ts) value.

In operation 607, the electronic device according to one embodiment may determine whether the external temperature value exceeds a reference external temperature level. If the determination result shows that the external temperature value exceeds the reference external temperature level, the electronic device may perform operation 609, and otherwise, the electronic device may perform operation 611.

In operation 609 (operation 607-Example), the electronic device according to one embodiment may set a relatively large brightness control value (e.g., a maximum brightness control value) as a first brightness control value based on the first brightness control information. The electronic device may obtain a brightness control value (e.g., a set value) included in the first brightness control information in response to the obtained external temperature value, and set the obtained brightness control value as the first brightness control value. For example, if the electronic device determines that the acquired surface temperature value of the electronic device is a first surface temperature level (e.g., a temperature value in a range from 40 degrees or more than 38 degrees to 40 degrees or less) that exceeds a first reference temperature level (e.g., 38 degrees) and the acquired external temperature value is a first external temperature level (e.g., a temperature value in a range from 30 degrees or more than 25 degrees to 30 degrees or less) that is greater than a reference external temperature level (e.g., 25 degrees), as illustrated in FIG. 3A, the electronic device may acquire a brightness control value (e.g., a brightness value of 600 nt or 800 nt) specified in response to the first surface temperature level and the first external temperature level, and set the first brightness control value to the acquired brightness control value (e.g., 600 nt or 800 nt). The external temperature levels and surface temperature levels specified in the first brightness control information can each be pre-specified through experiments, and can be set to other values or ranges than the levels or ranges set in FIG. 3a depending on at least one of the device type, the usage environment (e.g., outdoors, indoors, weather, or usage time), or the factors related to heat generation (e.g., usage application). When performing the 609 operation, the illuminance value may not be considered or may be determined to be a level exceeding the reference illuminance level (e.g., 3000 lux) (e.g., the first illuminance level or the second illuminance level in FIG. 3a).

In operation 611 (operation 607-No), the electronic device according to one embodiment may set the first brightness control value based on the second brightness control information. The electronic device may acquire a brightness control value (e.g., a set value) included in the second brightness control information in response to the acquired illuminance value, and set the first brightness control value with the acquired brightness control value. For example, as illustrated in FIG. 3B, if the acquired surface temperature value of the electronic device is a first surface temperature level (e.g., a temperature value of 40 degrees or more than 38 degrees but less than or equal to 40 degrees) exceeding a first reference temperature level (e.g., 38 degrees) and the acquired external temperature value is less than or equal to a reference external temperature level (e.g., 25 degrees), the electronic device may acquire a brightness control value (e.g., a luminance value of 400 nt) specified in response to the first surface temperature level and the reference external temperature level, and set the first brightness control value with the acquired brightness control value (e.g., 400 nt). The external temperature levels and surface temperature levels specified in the second brightness control information can each be pre-specified through experiments, and can be set to other values or ranges than the levels or ranges set in FIG. 3b depending on at least one of the device type, the usage environment (e.g., outdoors, indoors, weather, or usage time), or the factors related to heat generation (e.g., usage application). When performing the 611 operation, the illuminance value may not be considered or may be determined to be a level exceeding the reference illuminance level (e.g., 3000 lux) (e.g., the first illuminance level or the second illuminance level in FIG. 3b).

In operation 613, the electronic device according to one embodiment can check whether the first brightness control value is less than the current brightness value. If the check result shows that the set brightness control value is less than the current brightness value, the electronic device can perform operation 615, and if not, can perform operation 601.

In operation 615, the electronic device according to one embodiment can change the brightness of the display with the set first brightness control value.

Although FIG. 5 described above describes an operation of setting a first brightness control value based on a surface temperature value and an illuminance value, and FIG. 6 describes an operation of setting a first brightness control value based on a surface temperature value and an external temperature value, an electronic device according to one embodiment may set the first brightness control value based on all of the surface temperature value, the external temperature value, and the illuminance value. For example, as illustrated in FIG. 3A, if the electronic device determines that the acquired surface temperature value is a first surface temperature level (e.g., a temperature value in a range from 40 degrees or more than 38 degrees to 40 degrees or less) that exceeds a first reference temperature level (e.g., 38 degrees), the acquired external temperature value is a first external temperature level (e.g., a temperature value in a range from 30 degrees or more than 25 degrees to 30 degrees or less) that exceeds a reference external temperature level (e.g., 25 degrees), and the illuminance value is a first illuminance level (e.g., an illuminance value in a range from more than 3000 lux to less than 10000 lux), the electronic device may acquire a brightness control value (e.g., a luminance value of 600 nt) specified in response to the first surface temperature level, the first external temperature level, and the first illuminance level, and set the first brightness control value to the acquired brightness control value (e.g., 600 nt).

According to one embodiment, the electronic device may pre-designate third brightness control information for setting the first brightness control value and store it in the memory (130). The electronic device may set the brightness control values set for each of the surface temperature levels set in response to the first illuminance level (e.g., illuminance value exceeding 3000 lux and below 10000 lux) at a temperature lower than the second reference temperature (e.g., below 47 degrees Celsius) in the third brightness control information to be higher by the set first ratio (e.g., 25% with respect to the reference illuminance level of FIG. 3C ). The electronic device may set the brightness control values set for each of the surface temperature levels set in response to the second illuminance level (e.g., illuminance value exceeding 10000 lux) at a temperature lower than the second reference temperature (e.g., below 47 degrees Celsius) in the third brightness control information to be higher by the set second ratio (e.g., 50% with respect to the reference illuminance level of FIG. 3C ). Here, the third brightness control information may be set to a higher ratio (e.g., a constant ratio specified through an experiment or by a user) than the brightness control values specified for the reference illuminance level (e.g., 3000 lux or less) for each of the surface temperature levels (e.g., 400, 300, 200, 150) or the basic brightness control values (e.g., 400, 300, 200, 150) set in the second brightness control information of FIG. 3b.

According to one embodiment, the electronic device may set the brightness control range to the existing 80% to 30% when heat generation occurs if it does not change to the first brightness control value, and may change the brightness control range to 160% to 30% when heat generation occurs (e.g., change according to tuning) if it changes to the first brightness control value. For example, a brightness control range of 100% may be the first brightness control value when brightness is manually set.

An electronic device according to one embodiment may continuously detect and learn a surface temperature and an external temperature, and may set a first brightness control value (e.g., a maximum brightness control value) according to a user request or automatically to change the display brightness. An electronic device according to one embodiment may set a maximum brightness control value based on an external temperature value and/or an illuminance value according to a specific condition (e.g., execution of an application that generates a lot of heat, a time period specified by a user, or a condition due to a factor related to heat generation of the electronic device other than the above), and may change the brightness of the display according to the set maximum brightness control value.

FIG. 7 is a diagram showing an example of current consumption and temperature measurement according to external temperature and display brightness in an electronic device according to one embodiment.

Referring to FIG. 7, an electronic device according to a temporary example can use experimental tables (701 and 702) obtained through an experiment to check whether the change in current consumption and the change in temperature according to the external temperature change for each brightness value (e.g., brightness code) affect the improvement of surface heat generation. Here, the experimental tables (701 and 702) may be tables that record the change in current consumption and the change in temperature according to the brightness values when the same application (e.g., the first application or the second application) is used in the same scenario while changing the external temperature. Based on the result values of the experimental tables (701 and 702), it can be confirmed that reducing the brightness is no longer effective in improving heat generation when the external temperature increases, and it can be seen that when heat generation is actually increased due to an external factor, even if the internal current consumption of the electronic device is reduced, the effect of the external factor cannot be offset. Accordingly, in an environment where the external temperature is higher than a certain temperature or the temperature of the electronic device may increase due to illuminance values (e.g. direct sunlight), it can be confirmed that general control may only lower visibility, and that there is no significant difference in the heat generation control effect even if it is applied only to the extent of a control device for stability at a higher temperature.

Conventional electronic devices control relatively high brightness (e.g., maximum brightness) only based on the temperature of the electronic device without considering the external environment, so when the temperature of the electronic device rises due to direct external sunlight, the brightness is proposed according to a table determined only for the purpose of heat generation control. Conventional electronic devices control the brightness of the display without considering the external environment, so the brightness is limited by heat generation, which reduces the visibility of the display, and causes inconvenience in the use of the electronic device.

The present document may provide an electronic device and method for controlling the brightness of a display based on external temperature and/or illuminance values, taking into account the surface temperature of the electronic device and external conditions according to one embodiment.
