Method for driving touch-and-display device, driving circuit, and touch-and-display device

A driving method for an OLED touch-and-display device comprises a display panel, wherein the display panel comprises a plurality of rows of pixels and a plurality of gate driving lines (GL) in one-to-one correspondence, and the driving method comprises the following steps:

• generating gate driving signals that are sequentially shifted according to a clock cycle of a clock signal (GCK), based on the clock signal, wherein each of the gate driving signals comprises an active pulse having a pulse width smaller than the clock cycle of the clock signal;
• sequentially applying the gate driving signals to the plurality of gate driving lines;
• for each row of pixels, writing display data in a display driving period for the row of pixels, wherein the display driving period is arranged in a period of the active pulse of a gate driving signal applied to a gate driving line corresponding to the row of pixels;
• and
• setting a touch detection period for touch detection in a gap interval of active pulses of two adjacent gate driving signals respectively corresponding to two adjacent rows of pixels among the plurality of rows of pixels.
