Abstract

A display has an array of pixels controlled by display driver circuitry. Gate driver circuitry supplies gate line signals to rows of the pixels. The pixels may be liquid crystal display pixels. Each pixel may have a common electrode voltage terminal. The display may have a transparent conductive film that forms a common electrode voltage layer that overlaps that array and that is shorted to the common electrode voltage terminals of the pixels. Metal common electrode voltage lines may run across the transparent conductive film to reduce resistance. Metal common electrode voltage paths that are coupled to the metal common electrode voltage lines may run along the left and right edge of the display. Common electrode voltage compensation circuits may receive feedback from the metal common electrode voltage paths. There may be two or more common electrode voltage compensation circuits for both the left and right edges of the display.
