Abstract
An apparatus having a touch-sensitive screen, a touch-sensor controller and a flexible printed circuit. A plurality of first conductive electrodes and a plurality of second conductive electrodes are substantially aligned with one or more gaps between two or more pixels of a two-dimensional array of pixels such that the electrodes do not cross over at least one of the pixels of the two-dimensional array of pixels. The plurality of first conductive electrodes form vertices within the one or more gaps between two or more pixels of the two-dimensional array of pixels such that the vertices do not obscure in plan view at least one of the pixels of the two-dimensional array of pixels. The touch-sensor controller is configured to detect and process the change in capacitance at one or more touch-sensor nodes to determine the presence and location of a touch-sensor input.
