Abstract

The embodiment of the invention discloses a backlight adjusting method and device. The method comprises the steps of obtaining the current light brightness of ambient light at the current moment; determining a brightness change trend corresponding to the ambient light according to the current light brightness and the ambient light brightness collected at the previous moment; determining a target backlight grade corresponding to the current light brightness according to a preset corresponding relationship between the hysteresis brightness and the grade and the brightness change trend, the preset corresponding relationship between the hysteresis brightness and the grade comprising a preset corresponding relationship between the rising hysteresis brightness and the grade or a preset corresponding relationship between the falling hysteresis brightness and the grade; when ambient light fluctuates within a certain range, the backlight level can be stably output, the flickering phenomenon that the screen flickers suddenly is avoided, the visual perception is improved, and the service life of the display screen is prolonged.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a backlight adjustment method and device. Background technique [0002] With the development of society, the popularity of cars in today's society is getting higher and higher. Among them, the instrument panel is a relatively important part of the car, which can provide the driver with intuitive data to help driving. For example, the current full digital instrument panel is made of crystal material, which emits light through the backlight screen, so that the numbers on the instrument panel And the indicator light is clearly visible, and the driver can know in real time his driving speed, mileage, remaining amount of oil, whether the indicator light is on, and other data. [0003] Among them, due to the complex environment changes in the use scene of the car, the light intensity of the ambient light will change. In order to ensure that the display content on the inst...
