DEVICE AND METHOD FOR DRIVING A SELF-LUMINOUS DISPLAY PANEL

Abstract:

A display driver comprises gamma processing circuitry, compensation circuitry, and driver circuitry. The gamma processing circuitry is configured to process the image data to generate gamma processed image data. The compensation circuitry is configured to process the gamma-processed image data, based on a ratio of a number of display elements that emit light to a total number of display elements of a display panel, to generate compensated image data. The driver circuitry is configured to drive the display panel based on the compensated image data.
