Abstract:
A driving method for a touch screen is disclosed. The touch screen includes a display panel, a touch panel, and a control circuit. Each of a plurality of display cycles includes at least two first time sequences and at least two second time sequences. The method includes, during each of the first time sequences, generating a plurality of scanning control signals for a display scanning line driving circuit, and, in response to the scanning control signals, delivering a plurality of scanning signals to different display scanning lines. The method also includes, during each of the second time sequences, generating a plurality of scanning control signals for the touch scanning line driving circuit, and, in response to the scanning control signals for the touch scanning line driving circuit, sequentially delivering scanning signals to all of the touch scanning lines of the touch panel.
