Abstract
A resistive multi-touch device includes a touch panel, a matrix, a scanning circuit, a first multiplexer, a second multiplexer, and a touch controller. The matrix includes m pairs of first electrodes forming m columns and n pairs of second electrodes forming n rows. The scanning circuit detects which column of first electrodes is touched to generate a first selecting signal and which row of second electrodes is touched to generate a second selecting signal according to a predetermined scanning mode. The first multiplexer selects a first signal of the touched first electrode from signals transmitted on the first electrodes according to first selecting signal. The second multiplexer selects a second signal of the touched second electrode from signals transmitted on the second electrodes according to second selecting signal. The touch controller calculates coordinate value of touched point according to first signal and second signal.
