Abstract
Systems and methods for improving display image quality on electronic displays are provided. One embodiment of an electronic display includes display pixels that share a common electrode. Each of the display pixels includes a first conductive path electrically coupled between a pixel electrode and a data line, in which the first conductive path only enables the data line to charge the pixel electrode; and a second conductive path electrically coupled between the pixel electrode and the data line in parallel with the first conductive path, in which the second conductive path enables the data line to discharge the pixel electrode such that discharge rate of the pixel electrode is approximately equal to charge rate of the pixel electrode. Additionally, the embodiment includes a touch pixel that detects occurrence and position of a touch on a screen of the electronic display using the first common electrode.
