摘要： 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.

摘要： A switching control device, a control method, and a display device are provided. The switching control device includes: a main control circuit and switch control circuits in one-to-one correspondence with display screens. The main control circuit is configured to output a display control voltage, and output in a time-division manner a display switching instruction in one-to-one correspondence with each of the display screens. For each of the display screens, the display switching instruction includes: a switch control signal, a data signal, a lighting signal, and an extinguishing signal. The main control circuit is configured to output a lighting signal to the corresponding display screens, and to output an extinguishing signal to the corresponding display screens. The switch control circuits are configured to receive a display control voltage and a switch control signal, and supply a display control voltage to the corresponding display screens.

摘要： A power circuit of a display panel and a display panel. The power circuit comprises a sensing circuit and a voltage output circuit. The sensing circuit is configured to provide a sensing signal indicative of a type of an image to be displayed by the display panel. The voltage output circuit is electrically connected to common electrodes of the display panel and configured to receive the sensing signal and change potentials of some of the common electrodes in response to a change in the sensing signal.
