Abstract
A gray-scale compensation device and method for combined pixels, and a display device. The compensation method for the combined pixels includes: measuring a gamma curve of the first pixel group to obtain a first gamma curve; measuring a gamma curve of the second pixel group to obtain a second gamma curve, where an area of the first pixel group is different from an area of the second pixel group; obtaining a compensation voltage based on the first gamma curve and the second gamma curve; and compensating the first pixel group or the second pixel group based on the compensation voltage.
