Please refer to FIG. 2. FIG. 2 is a schematic flowchart of a backlight adjustment method provided by an embodiment of the present application, which is applied to a mobile terminal. The backlight adjustment method includes:

S201. When the mobile terminal detects that the user is using the mobile terminal, acquire system state information of the mobile terminal;

Wherein, the system status information of the mobile terminal includes but not limited to time information, location information, application program information running in the foreground, horizontal and vertical screen status, posture information, and the like.

Wherein, one usage scene corresponds to one type of backlight response curve, and the corresponding relationship between the two can be set in advance.

S204. The mobile terminal adjusts a backlight module of the mobile terminal according to the backlight response curve.

It can be seen that in the embodiment of the present application, when the mobile terminal first detects that the user is using the mobile terminal, it obtains the system status information of the mobile terminal; secondly, it determines the user's usage scenario according to the system status information; A set of backlight response curves is used to obtain a backlight response curve adapted to a usage scenario. The set of backlight response curves includes a correspondence between the usage scenario and the backlight response curve. Finally, the backlight module of the mobile terminal is adjusted according to the backlight response curve. It can be seen that the mobile terminal can obtain an exclusive backlight response curve adapted to the current use scene based on scene recognition, thereby realizing accurate backlight brightness adjustment according to the backlight response curve for the use scene, and improving the accuracy and intelligence of backlight brightness adjustment.

In a possible example, the mobile terminal adjusts the backlight module of the mobile terminal according to the backlight response curve, including: the mobile terminal acquires the ambient light intensity of the environment where the mobile terminal is located; acquires the usage scene corresponding the high-frequency usage area of the touch display screen of the mobile terminal; and adjust the backlight module of the mobile terminal according to the high-frequency usage area and the ambient light intensity.

Among them, when the head user of the mobile terminal uses the mobile terminal in different usage scenarios, the operating habits of the touch screen display of the mobile terminal can be calculated by analyzing historical touch data. The area corresponding to frequent operations may be the skill release area and the position control area, and the area corresponding to frequent operations in the vertical screen e-book reading scene may be the page turning position, etc.

It can be seen that in this example, the mobile terminal can dynamically adjust the backlight module according to the user's high-frequency usage area corresponding to the current usage scene, so as to improve the intelligence and flexibility of backlight adjustment.

In a possible example, the backlight module includes an LED assembly composed of a plurality of light-emitting diodes (LEDs); the mobile terminal adjusts the backlight module of the mobile terminal according to the high-frequency use area and the ambient light intensity , including: the mobile terminal divides the plurality of LEDs into a first LED set and a second LED set according to the high-frequency usage area, wherein the illumination range of any LED in the first LED set includes the high High-frequency use area, the irradiation range of any LED in the second LED set does not include the high-frequency use area; determine the first driving signal for the first LED set and the second LED set for the second set Two drive signals: drive the LEDs in the first LED set according to the first drive signal, drive the LEDs in the second LED set according to the second drive signal, and the first drive signal is greater than the first drive signal Two driving signals.

It can be seen that in this example, the mobile terminal differentially drives the LEDs in the backlight module based on the user's high-frequency use area, so as to meet the user's operating needs while reducing backlight power consumption as much as possible and improving performance balance.

In a possible example, the usage scene is a car navigation scene, the initial location of the car navigation scene is the parking lot of the user's home, and the target location of the car navigation scene is the user's office parking lot; the backlight response The curve includes correspondences between multiple positions and the brightness of the backlight module, each correspondence is associated with the ambient light intensity of a reference position, and the reference position is a preset in the navigation route associated with the vehicle navigation scene position; the mobile terminal adjusts the backlight module of the mobile terminal according to the backlight response curve, including: after the mobile terminal acquires the ambient light intensity at the preset position, turn off the ambient light sensor; query the backlight response curve, obtaining a corresponding relationship corresponding to the ambient light intensity; obtaining the real-time position of the mobile terminal; determining the target brightness value of the backlight module according to the real-time position and the corresponding relationship; according to the target brightness value to adjust the backlight of the backlight module.

The preset position can be the position where the initial stage of the navigation route is in the open air, so that the weather conditions of the day can be accurately determined, and the navigation time corresponding to the navigation route generally does not exceed the preset time length, so as to avoid the occurrence of weather conditions due to the driving time process. The status of the situation changes. Of course, in this case, the mobile terminal can detect and switch the backlight adjustment strategy in time, such as turning on the light sensor for dynamic adjustment.

It can be seen that in this example, because the car is in a high-speed driving state in the car navigation scene, the traditional strategy of dynamically adjusting the backlight brightness of the mobile terminal through the light sensor is difficult to achieve a good balance in terms of accuracy, real-time and power consumption.
