摘要： A resistive input system is disclosed, which includes a resistor matrix. The resistor matrix includes M first traces, N second traces, and M*N resistors. First ends of the resistors of a same column are coupled to one of the M first traces, second ends of the resistors of a same row are coupled to one of the N second traces, M is integers greater than 1, and N is integers greater than and equal to 1. The M*N resistors include variable resistors. A measurement circuit measures variations of a first voltage level of each of the second traces while a power control circuit provides the first voltage to the one of the M first traces and the second voltage to the rest of the M first traces. At least one input point is determined according to the variation of the first voltage level of each of the second traces.

摘要： A method for controlling an input device is provided. The input device has a resistor matrix having M first traces, N second traces and M×N resistors. Each second trace is coupled to a reference resistor and M−1 variable resistors. M and N are integers greater than 1. A first voltage level of each second trace is measured when a first voltage is applied to a first end of the reference resistor and a second voltage is applied to first ends of the M−1 variable resistors via the M first traces. Variations of the first voltage level of each second trace are measured, such that it could be determined whether any touch point of the input device exists according to the variations of the first voltage level of each second trace.
