Abstract:
The present disclosure relates to systems and methods of accounting for the kickback voltage in an LCD display. For example, a method may include obtaining, via a processor, a difference between a nominal voltage of a common electrode of a display and a measured voltage of the common electrode. The processor may obtain image data associated with an image to be displayed on the display. The processor may adjust the image data of a pixel of the display based on the difference. The processor may output an image signal indicative of the adjusted image data to a pixel electrode of the pixel.
