Abstract

The present invention provides a backlight control method and device applied to the turn-on process of the screen of an electronic device. The method comprises the following steps that: after the backlight of the electronic device is initialized based on a screen turn-on command, dynamic backlight luminance is received, wherein the dynamic backlight luminance is stored in the SoC main chip of the electronic device; whether the luminance difference of the current backlight luminance of the electronic device and the dynamic backlight luminance is greater than a preset threshold value is determined; and if the luminance difference of the current backlight luminance of the electronic device and the dynamic backlight luminance is greater the preset threshold value, the backlight luminance of the electronic device is adjusted from the current backlight luminance to the dynamic backlight luminance in a step-by-step manner. With the method adopted, the problem of the instantaneous jump of the backlight luminance during the turn-on process of the screen of the electronic device in the prior art can be solved, and the visual experience of a user can be improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment control, and in particular to a backlight control method and device when an electronic equipment is turned on. Background technique [0002] In the prior art, after the screen-off operation is performed on the electronic device, the backlight control chip of the electronic device is in a power-off state, and then, after the screen-on operation is performed on the electronic device, the SoC main chip of the electronic device will re-control the power control board Supply power to the backlight control chip; after the backlight control chip is powered on, the switch MCU of the electronic device will re-initialize the backlight control chip to set the initial backlight brightness, and the backlight control chip will light the backlight panel according to the initial backlight brightness, usually to In other words, the brightness of the backlight set in the initialization proces...
