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: generating gate driving signals that are sequentially shifted based on the first clock signal (GCK); sequentially applying the gate driving signals that are sequentially shifted to the plurality of GLs; writing display data in a display driving period for each row of pixels, to the row of pixels, wherein a time length of the display driving period depends on a corresponding gate driving signal and is smaller than the clock cycle; and for a display driving period for each of at least one row of pixels, setting a touch detection period corresponding to the display driving period or corresponding to the display driving period for previous row of pixels at least partially overlapping with the display driving period in time.

Abstract: The disclosure provides a method for driving an OLED touch-and-display device, a driving circuit, and the 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 them to at least a part of gate driving lines of the plurality and corresponding light-emission control lines; during each touch detection period: suspending the generation of gate driving signals or also suspending the generation of light-emission control signals; adjusting the average display luminance of a plurality of rows of pixels within a predetermined time period, so that the display luminance is uniform, and the gate driving signal for each row of pixels and the light-emission control signal of the light-emission control line maintain a preset timing relationship.
