The touch signal output by the touch sensor is received by the touch sensing controller, and converted into a corresponding touch digital signal and output. Step S12: Acquire a light intensity signal in the external environment, and convert it into a corresponding light intensity digital signal. For example, a light sensor can be used to obtain a light intensity signal in an external environment. At present, the application of light sensors is more common. For example, in some mobile phones or digital cameras, a light sensor is disposed around the camera to obtain the ambient light of the camera.
