Abstract:
A system and method for reducing electromagnetic interference of a display device. The display device may have a plurality of gate electrodes and a plurality of common electrodes. Further, the display device includes a processing system that is configured to drive a first gate electrode of a plurality of gate electrodes of the display device with a first gate select signal to select first subpixels for updating during a first period. The processing system further comprises driving a first common electrode proximate the first gate electrode with a reference signal during the first period. Further, the processing system is configured to drive a second common electrode with a first interference reduction signal during the first period to reduce the electromagnetic interference of the display device.
