1. A display panel comprising:
a first display part;
a second display part located on at least one side of the first display part;
a plurality of pixel driving circuits electrically connected to the first display part and the second display part;
a plurality of gate driving units, each gate driving unit comprising a first output unit, a second output unit, and an output terminal electrically connected to a corresponding pixel driving circuit of the pixel driving circuits, the first output unit and the second output unit being configured to output a gate signal to a gate of at least one transistor of the pixel driving circuit in response to a voltage of a first node and a voltage of a second node, respectively;
wherein the plurality of gate driving units comprise a plurality of first gate driving units arranged in cascade and electrically connected to the first display part; and
wherein each first gate driving unit includes a constant voltage control unit electrically connected to the first node or the second node, and the constant voltage control unit is configured to transmit a node control voltage to the first node or the second node in response to a switching control voltage, so that the first display part is always in a non-display state within a duration of at least one frame.
