  • Patent number: 11942020
    Abstract: Disclosed is a driving circuit including an input circuit, a first output circuit, a second output circuit and a pull-down circuit. Control terminals of the first output circuit and the second output circuit are connected with an output terminal of the input circuit and receive a control signal from the input circuit, and output terminals of the first output circuit and the second output circuit are connected with the pull-down circuit and receive a pull-down signal. Thus, two stages of driving signals output by one stage driving circuit is realized. As compared with the existing architecture under which the two stage driving circuit is needed to output two stages of driving signals, one input circuit and one pull-down circuit are removed. This application also discloses a four-stage driving circuit and a display panel. The number of used components is reduced, and the frame of the display product is narrowed.
