Abstract
A converter capable of making a five-wire or six-wire resistive touch screen compatible with a four-wire controller comprises an encode-decode circuit composed by at least two multiplexers and a signal amplification analog circuit; wherein the signal amplification analog circuit receives, analogizes and amplifies and inputs the signals transmitted by the four-wire controller to the encode-decode circuit thereby controlling the multiplexers whether to receive or process a non-encoded voltage signal and to output the voltage signal re-encoded by the multiplexers. Therefore, it recomposes, re-encodes and re-decodes the voltage signals (I/O signals) output or input by a five-wire or a six-wire touch screen so as to make the processed voltage signals compatible with the four-wire controller for processing.
