摘要:
The screen-input image display device has a touch panel for outputting touched locations of a finger or the like in contact with a display panel screen; and a sensing circuit for sensing coordinates of the touched locations based on the output of the touch panel. The touch panel has a transparent conductor film which is single layer on a transparent substrate, the transparent conductor film being patterned into numerous electrode pads arranged in rows and columns of a two-dimensional matrix, and surface areas of the electrode pads vary depending on the location of the touch areas. Coordinates of the touch locations are sensed based on the proportion of charge signals of the touch locations due to differences in surface areas of the electrode pads.
