Abstract:
1. A capacitive touch screen comprising: a TFT layer; a plurality of display pixels positioned on the TFT layer; each display pixel comprising a pixel electrode; one or more common electrodes positioned on the TFT layer; each pixel electrode operatively coupled to one of the one or more common electrodes to provide a display function in a display mode of operation; a color filter substrate; the thin film transistor (TFT) layer including a plurality of drive lines, wherein the drive lines are configured to transmit stimulation signals, the stimulation signals used to stimulate the capacitive touch screen for the purpose of detecting touch input events, each drive line configured from the one or more common electrodes in a touch sensing mode of operation; a pixel material disposed between the TFT layer and the color filter substrate; and a plurality of sense lines disposed on a side of the color filter substrate facing the pixel material, wherein the sense lines are configured to receive signals based on the stimulation signals transmitted by the drive lines and wherein the drive lines and the sense lines form a plurality of capacitive sensing nodes.
