Abstract: An integrated touchscreen comprises display pixels arranged in a two-dimensional matrix of rows and columns to minimize the reduction in aperture ratio of the display pixels. A matrix of touch element is defined in the display pixels, with a touch unit cell encompassing a group of display pixels. A touch element is comprised of a matrix of touch unit cells. The common electrodes of the display pixels encompassed in the touch element are electrically connected together to form a common electrode for the touch element. The touch unit cell includes conductive lines extending in the row direction and conductive lines extending in the column direction. The touchscreen comprises a controller that can operate in either one of a self-capacitance touch sensing mode and a mutual-capacitance touch sensing mode.
