发明名称 Screen Input-Type Image Display System
摘要 A touch sensor (3) comprises a plurality of X-coordinate electrodes, a plurality of Y-coordinate electrodes placed crossing the X-coordinate electrodes with an insulating layer therebetween, a plurality of X-coordinate auxiliary electrodes which are extended from X-coordinate electrodes, and a plurality of Y-coordinate auxiliary electrodes which are extended from Y-coordinate electrodes, the plurality of X and Y-coordinate electrodes being placed in a two-dimensional matrix form on a display surface of a display device (1) for detecting a change of capacitance due to pressing. A detection circuit (4) which detects a change in capacitance of the touch sensor (3), an analog-to-digital converter (5) which converts a detection output of the detection circuit (4) into digital data, a touch panel control circuit (6) which determines a touched coordinate, and a primary control circuit (7) which receives input of touch coordinate data from the touch panel control circuit (6) are provided.
