    摘要: 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.

    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.
