Abstract
A light regulation method is described that includes: obtaining actual brightness of light of a first color in a pixel unit, based on brightness and color coordinate of a pinhole light-emitting area, brightness and color coordinate of a first sub-pixel light-emitting area in the pixel unit, and relative position information of the pinhole light-emitting area and the pixel unit; obtaining 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, a second sub-pixel light-emitting area and a third sub-pixel light-emitting area; and comparing the actual brightness with the standard brightness of the pixel unit, and changing the brightness of the first sub-pixel light-emitting area 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.
