A touch display apparatus including a touch display panel and a control circuit is provided. The touch display panel includes a touch display array, a gate driver, and a sleep driving circuit. The gate driver is coupled to the touch display array to sequentially provide a plurality of gate driving signals. The sleep driving circuit is coupled to the touch display array. The control circuit is coupled to the gate driver and the sleep driving circuit. When the touch display apparatus enters a sleep state, the sleep driving circuit is turned on. The control circuit cuts off the gate driver during a display period and transmits a driving pulse to the touch display array through the sleep driving circuit during a touch sensing period.
