Abstract

A plane display device has row electrodes and column electrodes, wherein the electrodes in a direction are used as touch control electrodes for sensing touch control, and leading ends which are connected to a touch control signal circuit are formed on both ends of the electrodes in this direction. Different touch control positioning modes are used in the orthogonal direction, respectively. The digital touch control positioning mode is applied in the direction perpendicular to the electrodes, and the positions of the touch control electrodes are determined by comparing the difference of the touch control signals sensed by the different electrodes. The analog touch control positioning mode is applied in the direction parallel to the electrodes, and the positions of touch points on the touch control electrodes are determined by comparing the difference of the touch control signals on the ends of the touch control electrodes. Therefore, the position of touching point on a plane of the touch control screen can be obtained.
