Patent ID: 8159473

Claim:
A touch panel, comprising: a resistive pressure-sensing matrix, which comprises M X-axis sensing lines and N Y-axis sensing lines, wherein an i th X-axis sensing line and a j th Y-axis sensing line are short-circuited when a preset range covering an overlapped region between the i th X-axis sensing line and the j th Y-axis sensing line of the resistive pressure-sensing matrix is pressed; a sequence scan driver having N driving terminals respectively coupled to the N Y-axis sensing lines; and M X-axis sensing circuits, wherein: a k th X-axis sensing circuit is coupled to a k th X-axis sensing line; a sensing period of the touch panel is divided into N scanning periods, and a p th driving terminal of the sequence scan driver outputs a scanning voltage in a p th scanning period; a q th X-axis sensing circuit receives the scanning voltage so that a touch coordinate is determined as (q, p) when the preset range covering the overlapped region between a p th Y-axis sensing line and a q th X-axis sensing line is pressed in the p th scanning period; and M, N, i, j, k, p and q are positive integers, i ranges between 1 and M, j ranges between 1 and N, k ranges between 1 and M, q ranges between 1 and M, and p ranges between 1 and N.
