发明名称 TOUCH SENSING DEVICE AND DOUBLE SAMPLING METHOD THEREOF
摘要 A touch sensing device includes a touch screen including Tx lines, Rx lines crossing the Tx lines, and touch sensors formed at crossings of the Tx lines and the Rx lines, a Tx driving circuit for supplying a driving signal to each of the Tx lines N times, where N is a positive integer equal to or greater than 2, and an Rx driving circuit for double sampling signals received through the Rx lines in one period of the driving signal. The Rx driving circuit includes a multiplexer which receives first and second signals and switches on or off a signal transmission path of the first and second signals, and an integrator which samples and integrates the first and second signals received from the multiplexer.
