Abstract:
The disclosure provides a method for driving an OLED touch-and-display device, a driving circuit, and an OLED touch-and-display device. The method includes: dividing each display frame into at least one display period and at least one touch detection period which are alternated; during each display period, generating sequentially-shifted gate driving signals and sequentially-shifted light-emission control signals, and sequentially applying the sequentially-shifted gate driving signals to at least a part of gate driving lines, and sequentially applying the sequentially-shifted light-emission control signals to at least a part of light-emission control lines; during each touch detection period, suspending generation of sequentially-shifted gate driving signals without suspending generation of sequentially-shifted light-emission control signals; and during a period when a gate driving signal for each row of pixels is of active level, maintaining a light-emission control signal for the row of pixels at inactive level.
