Abstract
A backlight control method and an electronic device are provided. The backlight control method, comprises: determining an input state of an electronic device; and adjusting a backlight brightness parameter of an input area of the electronic device according to the input state of the electronic device, wherein the backlight brightness parameter of the input area of the electronic device is adjusted from a plurality of backlight luminance values that indicate a plurality of backlight brightness levels of the input area.
Claims18
A backlight control method, comprising:
- determining an input state of an electronic device which comprises an input area configured to input varied user data;
- and
- adjusting a backlight brightness parameter of the input area of the electronic device according to the input state of the electronic device, wherein the backlight brightness parameter of the input area of the electronic device is adjusted from a plurality of backlight luminance values that indicate a plurality of backlight brightness levels of the input area, and adjusting the backlight brightness parameter of the input area of the electronic device according to the input state includes:
- in response to determining the input state is a first input state, adjusting the backlight brightness parameter of the input area to a first backlight luminance value corresponding to the first input state, the input area in the first input state responding to a clicking operation within the input area;
- and
- in response to determining the input state is a second input state, adjusting the backlight brightness parameter of the input area to a second backlight luminance value corresponding to the second input state, the input area in the second input state responding to a handwriting operation within the input area;
- wherein a power consumption of the electronic device in the first input state is different from a power consumption of the electronic device in the second input state.
