Abstract

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.
