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.
