A luminance compensation method. According to the method, a central calibration point is acquired on the sampled image. A plurality of third calibration points is generated on the sampled image based on the central calibration point. The sampled image is divided into a plurality of regions to be corrected. A corrected position of each second calibration point in any one of the regions to be corrected is acquired for an initial position of each third calibration point in the region to be corrected. An affine transformation correction is performed on the sampled image based on the corrected positions of all the second calibration points and reference positions of the first calibration points corresponding to the second calibration points, so that a corrected image is acquired. And luminance data of a reference image is compensated to the sampled image.

Luminance compensation method and apparatus for display panel

Display devices are provided. The display device includes a display panel including subpixels and a drive assembly configured to transmit data signals to the display panel. The drive assembly includes a first storage module, a second storage module, and a fusion module. A first compensation table including first grayscale data corresponding to the subpixels is stored in the first storage module. A second compensation table including second grayscale data corresponding to the first grayscale data is stored in the second storage module. The fusion module is configured to call the first compensation table and the second compensation table, calculate target grayscale data corresponding to the first grayscale data according to the second grayscale data, and compensate the display panel according to a third compensation table merged by the target grayscale data and the first grayscale data.
