Title: GRAY-LEVEL COMPENSATION DEVICE AND METHOD FOR COMBINED PIXEL, AND DISPLAY DEVICE
Abstract:
Provided are a gray-level compensation device (400) and method (200) for a combined pixel, and a display device (500). The compensation method (200) for a combined pixel comprises: measuring a gamma curve of a first group of pixels (120) to obtain a first gamma curve (210); measuring a gamma curve of a second group of pixels (130) to obtain a second gamma curve (220), wherein an area of the second group of pixels (130) is different from an area of the first group of pixels (120); obtaining a compensation voltage on the basis of the first gamma curve and the second gamma curve (230); and performing, on the basis of the compensation voltage, compensation on the first group of pixels (120) or the second group of pixels (130) (240).
