Display panel, light regulation device and light regulation method thereof

A light regulation device for a display panel, the display panel comprising a pinhole light-emitting area, a first sub-pixel light-emitting area, a second sub-pixel light-emitting area, and a third sub-pixel light-emitting area of different colors, wherein a light-emitting color of the pinhole light-emitting area and a light-emitting color of the first sub-pixel light-emitting area are both a first color, the light regulation device comprising a sensor, a processor, and a memory;

• wherein the sensor is configured to obtain brightness and a color coordinate of the pinhole light-emitting area, brightness and a color coordinate of the first sub-pixel light-emitting area in any pixel unit around the pinhole light-emitting area, and color coordinates of the second sub-pixel light-emitting area and the third sub-pixel light-emitting area in the pixel unit;
• and
• the processor is configured to, through execution of program instructions stored in the memory, obtain actual brightness of light of the first color in the pixel unit, based on the brightness and color coordinate of the pinhole light-emitting area, the brightness and color coordinate of the first sub-pixel light-emitting area in the pixel unit, and relative position information of the pinhole light-emitting area and the pixel unit;
• obtain standard brightness of the light of the first color in the pixel unit under a preset gray-scale white balance, based on the color coordinates of the first sub-pixel light-emitting area, the second sub-pixel light-emitting area and the third sub-pixel light-emitting area;
• compare the actual brightness with the standard brightness of the pixel unit, change the brightness of the first sub-pixel light-emitting area based on a magnitude relationship between the actual brightness and the standard brightness, and reacquire the actual brightness of the light of the first color in the pixel unit, until the actual brightness of the light of the first color in the pixel unit is equal to the standard brightness of the light of the first color thereof;
• and obtain target brightness of the first sub-pixel light-emitting area under the preset gray-scale, wherein the target brightness of the first sub-pixel light-emitting area is the brightness of the first sub-pixel light-emitting area when the actual brightness of the light of the first color in the pixel unit is equal to the standard brightness of the light of the first color thereof.
