Abstract
Provided is a capacitance coupling type on-screen input image display device that enables multipoint detection in a short period of time. The on-screen input image display device includes: a detection circuit () for detecting a change in capacitance between the plurality of X coordinate electrodes and the plurality of Y coordinate electrodes of the touch sensor (); a touch panel control circuit () for determining a touched coordinate point; and a main control circuit () for receiving touch coordinate data from the touch panel control circuit (). The main control circuit () judges occurrence of a user's touch and coordinates of the occurrence from the touch coordinate data, and supplies a display signal corresponding to the judged coordinates to the display device () via the display control circuit (), whereby the display signal is reflected on the display.
