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.

Switching control device and control method thereof, and display device

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.

Power circuit for display panel, display panel and driving method thereof

There is provided a touch display device, which includes a touch display substrate, a drive circuit and at least one switch circuit. The touch display substrate includes plural common electrode blocks including plural first-shaped common electrode blocks and at least one second-shaped common electrode block. The drive circuit includes plural touch terminals and at least one common voltage output terminal, and each common electrode block is connected to one of the touch terminals through a touch line. Each switch circuit is connected to at least one of the at least one second-shaped common electrode block and a portion of the first-shaped common electrode blocks, and configured to cause the common electrode blocks connected to the switch circuit to be disconnected from (or connected to) each other and disconnected from (or connected to) a respective common voltage output terminal connected to the switch circuit.
