Backlight control method and system and mobile terminal

Abstract

The invention is suitable for the technical field of communication, and provides a backlight control method and system and a mobile terminal. The method comprises the following steps: receiving a touch and click instruction to generate a prompt massage which comprises a full-screen operation massage and a touch region operation massage; judging whether the touch and click instruction is a full-screen backlight open instruction according to the selection of the prompt massage by users; controlling all backlight devices to be opened and lightening the full-screen when the touch and click instruction is the full-screen backlight open instruction; calculating the coordinates of touch points of a user on a touch screen and the touch regions of the coordinates when the touch and click instruction is a touch region backlight open instruction, wherein the touch screen comprises at least two preset touch regions; finding out the backlight devices corresponding to the touch regions according to the touch regions of the coordinates; and controlling the backlight devices corresponding with the touch regions to be opened and lightening the touch regions. By the adoption of the method, only the backlight devices corresponding to the touch regions can be lighted, and the consumption of battery power is reduced.

Description

Technical field [0001] The present invention belongs to the field of communication technology, and in particular relates to a backlight control method, system and mobile terminal. Background technique [0002] By turning off the backlight regularly to keep mobile terminals such as mobile phones in a low energy consumption state, and to extend the working time of mobile terminals such as mobile phones, is currently a relatively common energy-saving solution. The specific implementation is as follows: When the user does not control the mobile phone or does not When a call or message is received, the mobile terminal automatically triggers the standby module and turns off the screen backlight; and once the user taps the trigger screen again, the LED lights behind the back panel of the mobile terminal all light up, and the mobile terminal restarts to work. [0003] However, the above-mentioned backlight energy-saving solution does not take into account the user's operating habits and op...
