Abstract
A touch display and method for controlling the same are provided. The touch display includes a gate driver circuit, a touch sensor and a display panel. The method includes: when the touch sensor detects no touch input signal, the gate driver circuit outputs a plurality of first gate signals to the display panel at a first frequency; and when the touch sensor detects a touch input signal, the gate driver circuit outputs a plurality of second gate signals to the display panel at a second frequency. The second frequency is smaller than the first frequency.

A touch display method for driving a touch display device comprising a gate driver circuit, a timing controller, a touch sensor module, and a display panel, the touch display method comprising:
- the gate driver circuit sequentially outputting a plurality of first gate signals to the display panel at a first frequency when the touch sensor module does not detect a touch input signal;
- and
- the gate driver circuit sequentially outputting a plurality of second gate signals to the display panel at a second frequency when the touch sensor module detects the touch input signal, wherein the second frequency is smaller than the first frequency;
- wherein the step of the gate driver circuit sequentially outputting the plurality of second gate signals to the display panel at the second frequency when the touch sensor module detects the touch input signal further comprises:
- the timing controller sequentially outputs a plurality of delay signals to the gate driver circuit when the touch sensor module detects the touch input signal, so that the gate driver circuit is switched from outputting the plurality of first gate signals at the first frequency to outputting the plurality of second gate signals at the second frequency.
A touch display device, comprising:
- a display panel;
- a touch sensor module integrated on the display panel;
- a gate driver circuit coupled to the display panel, the gate driver circuit configured to sequentially output a plurality of first gate signals to the display panel at a first frequency when the touch sensor module does not detect a touch input signal and configured to sequentially output a plurality of second gate signals to the display panel at a second frequency when the touch sensor module detects the touch input signal,
- wherein the second frequency is smaller than the first frequency;
- and
- a timing controller configured to sequentially output a plurality of delay signals to the gate driver circuit when the touch sensor module detects the touch input signal, so that the gate driver circuit is switched from outputting the plurality of first gate signals at the first frequency to outputting the plurality of second gate signals at the second frequency.
