Abstract
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.

A touch display apparatus, comprising:
- a touch display panel, comprising:
- a touch display array, having a plurality of touch display pixels and a plurality of gate lines;
- a gate driver, coupled to the gate lines and having a plurality of shift registers, wherein the shift registers provide a plurality of gate driving signals to the gate lines;
- and
- a sleep driving circuit, coupled to the gate lines and receiving a first signal and a gate turn-off signal, wherein the sleep driving circuit is controlled by the gate turn-off signal;
- and
- a control circuit, coupled to the gate driver and the sleep driving circuit,
- wherein the gate turn-off signal is enabled to turn on the sleep driving circuit when the touch display apparatus enters a sleep state, the control circuit cuts off the shift registers during a display period and transmits the first signal to the gate lines during a touch sensing period, and the first signal is a driving pulse.
