RESISTIVE TOUCH PANEL OF MATRIX STRUCTURE HAVING WAVE-SHAPED SENSING CHANNEL AND THE DEVICE OF TOUCH SCREEN THEREOF

摘要

PURPOSE: A resistive touch panel of matrix structure having wave-shaped sensing channel and a device of touch screen thereof are provided to give a plurality of logic resolutions without the increase of the additional sensing channel. CONSTITUTION: A sensing channel(101) has a wave shape of width and constant cycle in the longitudinal direction. A sensing cell has a pinwheel shape in the cross-domain of the sensing channel. The sensing cell senses the physical coordinates value assigned to each sensing cell and more than two neighboring sensing cells. The sensing cell has coordinates through the median computation between the sensed cells in the logic operation.
