Abstract: A touch display device. A touch display panel includes a source multiplexer switching the transfer of source signals to data lines. In a low power wake-up gesture (LPWG) mode in which a touch input is only sensed in a state in which a display function is off to reduce power consumption, a source multiplexer control signal is provided to set the source multiplexer in an on state, in synchronization with a touch sensing section in which a touch driving signal is provided. This can discharge electric charges generated within the display panel, thereby preventing display defects due to the electric charges.
