Specifically, when the display panel provided by the embodiment of the present invention is a liquid crystal display panel or an electronic paper display panel, the pixel driving circuit may be:

Fig. 5 is a schematic structural diagram of a gate unit according to an embodiment of the present invention, and IN some alternative embodiments, as shown IN fig. 5, the gate unit 7 includes a gate control terminal IN1 and an input terminal IN2, where the gate unit 7 further includes: a first gate switch tube 71, a first pole 711 of the first gate switch tube 71 being electrically connected to the input terminal IN2, a second pole 712 of the first gate switch tube 71 being electrically connected to the first output terminal OUT1, and a gate 713 of the first gate switch tube 71 being electrically connected to the gate control terminal IN 1; a second gate switch 72, wherein the first pole 721 of the second gate switch 72 is electrically connected to the input terminal IN2, the second pole 722 of the second gate switch 72 is electrically connected to the second output terminal OUT2, and the gate 713 of the second gate switch 72 is electrically connected to the gate control terminal IN 1; the first gate switching tube 71 is of a different type from the second gate switching tube 72.
Specifically, with continued reference to fig. 1, fig. 2 and fig. 5, since the types of the first gate switch tube 71 and the second gate switch tube 72 are different, when the control unit 0 transmits the gate signals to the gate of the first gate switch tube 71 and the gate of the second gate switch tube 72 through the gate control terminal IN1 at the same time, one of the first gate switch tube 71 and the second gate switch tube 72 may be IN the on state and the other may be IN the off state. For example, when the control unit 0 transmits the first gate signal to the gate of the first gate switching tube 71 and the gate of the second gate switching tube 72 through the gate control terminal IN1 of the gate unit 7, the first gate signal may turn on the first gate switching tube 71, so that the gate driver control signal outputted from the control unit 0 to the input terminal IN2 of the gate unit 7 can be transmitted to the first scan driving circuit 61 through the first output terminal OUT1, so that the first scan driving circuit 61 performs driving scanning of the auxiliary display area 12, wherein, since the second gate switching tube 72 is turned off by the first gate signal, the gate driver control signal outputted from the control unit 0 to the input terminal of the gate unit 7 cannot be transmitted to the second output terminal OUT2, the gate driver control signal cannot be transmitted to the second scan driving circuit 62, and the second scan driving circuit 62 cannot perform driving scanning on the main display region 11; similarly, when the control unit 0 transmits the second gate signal to the gate of the first gate switching tube 71 and the gate of the second gate switching tube 72 through the gate control terminal IN1 of the gate unit 7, the second gate signal can turn off the first gate switching tube 71 and turn on the second gate switching tube 72, so that the gate driver control signal output by the control unit 0 can only reach the second scan driving circuit 62 and cannot reach the first scan driving circuit 61, and thus the first scan driving circuit 61 cannot drive and scan the auxiliary display area 12, and the second scan driving circuit 62 can drive and scan the main display area 11. The first strobe signal and the second strobe signal may be opposite level signals, and for example, the first strobe signal may be a high level signal, and the second strobe signal may be a low level signal; or; the first strobe signal is a low level signal and the second strobe signal is a high level signal.
