Description

Intelligent terminal and backlight control system thereof and backlight automatic control method Technical field

The invention relates to a smart terminal lighting control technology, in particular to an intelligent terminal based on the MTK6260 platform, a backlight control system thereof and an automatic backlight control method.

Background technique

At present, most of the major mobile phone manufacturers in the prior art adopt the principle of light sensor, and automatically adjust the brightness of the screen of the mobile phone according to the brightness of the light of the mobile phone, so as to give the best visual effect. For example, in a dark environment, the screen of the phone will automatically dim, otherwise it will be dazzling. And can achieve the effect of power saving. The light sensor is composed of two components, a light projector and a light receiver. The light projector is used to focus the light from the lens, transmit it to the light receiver, and then receive the sensor, convert the light signal into an electrical signal, and transmit it to the mobile phone, thereby allowing The phone performs feedback to complete various controls.

However, prior art brightness control techniques have the following disadvantages:

1) The current implementation of the light-sensing solution, the software is highly dependent, can not let the customer adjust the brightness according to their preferences, there is no interactive interface that allows the customer to set up;

2) The current implementation of the light-sensing scheme, the hardware cost increases, the corresponding light-sensing components need to be added, the operating cost of the mobile phone is increased, and the light-sensing realization has a substantial increase in the power consumption of the mobile phone, and it is necessary to continuously detect the intensity of the surrounding optical signal;

3) It is difficult to implement on the function machine platform. Considering the cost and software achievability, the light perception is rarely increased on the function machine, and the detection and conduction of the signal will lead to an increase in power consumption.

In order to solve the power consumption problem, the Chinese patent (Public No.: CN1399458, Applicant: Yinghuada Co., Ltd.) discloses a method for automatically adjusting the brightness of the backlight of the mobile phone, as shown in Fig. 1, at a suitable position on the surface of a mobile phone. A photosensitive element (such as a photoresistor) is disposed, and the photosensitive element is connected to a control circuit of the mobile phone. When the user activates the backlight of the mobile phone to automatically adjust the brightness, a central processing unit (CPU) of the mobile phone The voltage value at both ends of the photosensitive element is determined, and according to the voltage value, the backlight of the mobile phone is adjusted to have a brightness corresponding to the voltage value, so that the resistance value of the photosensitive element is lowered under the environment of strong light irradiation, so that the resistance value thereof is lowered The voltage at both ends is lowered, and the resistance value in the dark environment will rise, so that the voltage value at both ends rises, making the phone The brightness of the backlight is adjusted to an appropriate high and low brightness, thereby reducing the power consumption of the backlight in a strong light environment.

As shown in FIG. 1 , the method for automatically adjusting the brightness of the backlight of the mobile phone includes: S101, performing backlight adjustment of the mobile phone as manual adjustment; S102, determining that the item for automatically adjusting brightness is enough to be selected, if jumping to S103; S103, reading Taking the voltage value at both ends of the photosensitive element; S104, adjusting the brightness corresponding to the mobile phone with the voltage value.

However, the backlight brightness adjustment method of the patent cannot allow the customer to adjust the brightness according to his preference, and realizes the light-sensing scheme, the hardware cost increases, the corresponding light-sensitive components need to be added, the operating cost of the mobile phone is increased, and the need for continuous detection is required. The intensity of the ambient light signal is strong, and the light perception in this patent has greatly increased the power consumption of mobile phones.

In addition, the Chinese patent (publication number: CN101374165, Applicant: ZTE Corporation) discloses a control device and method for backlighting of a mobile phone component, the control device comprising a photosensitive sampling module, a keyboard photosensitive control module, an LCD photosensitive control module, Keyboard operation control module, LCD operation control module, keyboard driver, LCD driver, keyboard backlight module and LCD backlight module.

As shown in FIG. 2, the control method includes the following steps: S201: The interrupt module causes the keyboard to sense the module according to the interrupt signal triggered by the user. S202. Determine whether the backlight of the component is turned on. If it is already open, skip to S203. Otherwise, the photosensitive sampling module is directly triggered and proceeds to step 204. S203. After the backlight of the waiting component is turned off, the photosensitive sampling module is triggered and proceeds to step S204. S204. The photosensitive sampling module samples the external light intensity of the mobile phone, and converts the sampled value into a voltage value. S205. Determine the current light intensity according to the voltage value. S206. Then, according to the current light intensity and the component backlight control rule, it is determined whether the component backlight needs to be turned on, and if necessary, the component backlight is turned on.

In this solution, separate control of the backlight of the mobile phone keyboard and the backlight of the LCD is realized by the photosensitive device. However, the use of light-sensing components has also led to an increase in the operating cost of the mobile phone, and the light perception has greatly increased the power consumption of the mobile phone, and it is necessary to continuously detect the intensity of the surrounding optical signal.
