    Abstract: The present disclosure provides a voltage driving method and device for a touch display panel, and a touch display panel, which includes a common electrode extending in a first direction and a plurality of columns of touch electrodes extending parallel to each other in a second direction. The voltage driving method includes: applying a first scanning voltage to two outermost columns of touch electrodes during a first period of a first touch cycle including a plurality of periods, the first scanning voltage being equal to a reference voltage; detecting a first output voltage output by the two outermost columns of touch electrodes during the first period; and adjusting, based on the detected first output voltage, the scanning voltage applied to the two outermost columns of touch electrodes during a first period of a second touch cycle immediately after the first touch cycle, to a second scanning voltage.

    Abstract: Provided are a shift register unit, a shift register, a display panel and a driving method thereof. The shift register unit includes: an input circuit electrically coupled to an input terminal, a first voltage terminal and a pull-up node; an output circuit electrically coupled to the pull-up node, a first clock terminal, a first scan control terminal, a first output terminal and a second output terminal; and a scan control circuit electrically coupled to the second output terminal, a second voltage terminal and a second scan control terminal. The input circuit is configured to write a first voltage provided by the first voltage terminal into the pull-up node in response to a start signal inputted to the input terminal. The output circuit is configured to output a first clock signal from the first clock terminal via the first output terminal, when the pull-up node is at the first voltage.
