Embodiment 1
[0049] Please refer to figure 1 , an embodiment of the present application provides a method for controlling a backlight, including:
[0050] S101: Collect a first brightness value of an environment where an input device including at least one key is located.
[0051] There are various ways to measure the brightness value in the environment. In the embodiment of the present invention, the brightness value of the environment can be determined by collecting infrared rays and ultraviolet rays in the environment. , specifically, the implementation process of collecting the first brightness value of the environment where the input device including at least one key is located may be:
[0052] First, collecting infrared or ultraviolet of an environment where an input device including at least one key is located;
[0053]Then, the intensity of the infrared rays or the ultraviolet rays is converted into an electrical signal intensity, and the first brightness value of the environment...
Embodiment 2
[0084] Please refer to figure 2 , an embodiment of the present application also provides a device for controlling a backlight, including:
[0085] a light collection module 201, configured to collect a first brightness value of an environment where an input device including at least one key is located;
[0086] The first control module 202, connected to the light collection module, is used to determine whether the first brightness value is less than a preset brightness value, and obtain a first determination result, where the first determination result indicates that the first brightness When the value is lower than the preset brightness value, a distance detection instruction is generated;
[0087] A distance detection module 203, connected with the first control module, is used to execute the distance detection instruction, and detect and obtain the actual distance value between an operating body and the input device;
[0088] The second control module 204, connected to the...
