It should be noted that when detecting the input of an image signal, the terminal acquires the mapping relationship between the image signal and the white balance digital signal and obtains the first digital signal according to the mapping relationship between the image signal and the white balance digital signal. It can be understood that the mapping relationship is specifically the LUT (display lookup table) of the image signal and the white balance digital signal. Whenever an image signal is input, the input image signal is used as an address to perform a lookup table, and then the Output the white balance digital signal corresponding to the address, and then output the white balance digital signal as the first digital signal.

It should be noted that the type of each pixel in the display panel is obtained, and then the first digital signal is processed according to the type of the pixel to obtain the second digital signal. The pixels in the display panel are mainly the main pixels and the sub-pixels. The terminal first obtains the type identification of the pixel, then determines the type of the pixel according to the type identification, then obtains the corresponding LUT according to the type of the pixel, and then sets the first The digital signal is used as an address of the LUT to perform a lookup table to find the second digital signal corresponding to the address.
