DISPLAYS WITH INTEGRATED TOUCH FUNCTIONALITY AND IMPROVED IMAGE PIXEL APERTURE

摘要

A display (10) is provided with integral touch functionality. The display (10) includes a common electrode layer having row electrodes (76; VCOMR) arranged in rows and column electrodes (VCOMC) interposed between the row electrodes of each row. The row electrodes are electrically coupled by conductive paths (74). The row and column electrodes are coupled to touch sensor circuitry (68) that uses the row and column electrodes to detect touch events. Each electrode of the common electrode layer covers a respective portion of an array of pixels (52). Each pixel of the display has a respective aperture (124). The conductive paths that electrically couple row electrodes of the common electrode layer covers or otherwise blocks some light (126) from passing through pixels, resulting in reduced apertures. Dummy structures (104) are provided for other pixels that modify the apertures of the other pixels to match the reduced apertures associated with the conductive paths.
