Abstract
A method for controlling light emission of a light sensing keyboard is to save in advance a driving correlation table including a plurality of driving codes in the light sensing keyboard. Each driving code corresponds to a trigger signal and is triggered by the trigger signal to generate a driving signal which defines a light emission mode. When a light detection unit detects ambient light parameters, the trigger signal is generated and the driving code corresponding to the trigger signal is read from the driving correlation table. A control unit generates the driving signal according to the driving code to drive light emission elements to emit light and also control each light emission element to execute the light emission mode corresponding to the driving signal, thereby synchronous or asynchronous colored light alteration can be generated to provide flickering or alternate light alteration effect.
