Abstract
A touch display and an anti-interference method thereof are provided. The touch display has a display panel, a touch panel, a touch chip, and a compensation circuit. A compensation signal line is led out from a common electrode layer of the display panel. A sensing signal line is led out from a touch layer of the touch panel. An input terminal of the compensation circuit is connected to the compensation signal line and the sensing signal line, and a compensated sensing signal is output to the touch chip from the output terminal. An ability of the touch screen to resist noise interference is improved.
