Abstract

A touch display device includes a controller, a source driver, several multiplexers, and several touch sensors. The source driver is configured to output several data signals. The multiplexers are coupled to the controller and the source driver, and are configured to transmit the plurality of data signals to an active area according to at least one enable period of a multiplexing signal. The touch sensors are coupled to the controller, and are configured to receive a touch signal outputted from the controller. The touch signal includes a touch pulse. A touch pulse starting-time interval and a touch pulse ending-time interval of the touch pulse are located in at least one disable period of the multiplexing signal, and the touch pulse and the at least one enable period partially overlap in time sequence.
