1. A display panel, comprising:

  • a plurality of gate lines;

    a plurality of data lines intersecting with the gate lines;

    a plurality of pixel units defined by the gate lines and data lines, each pixel unit comprising a pixel circuit;

    a plurality of voltage supply wires intersecting with the gate lines, each voltage supply wire electrically connected with the pixel circuit;

    a voltage supply terminal electrically connected to the voltage supply wires;

    a gate driving circuit, wherein the gate driving circuit comprises a plurality of output terminals, and at least one of the plurality of output terminals is electrically connected to at least one of the plurality of gate lines; and

    at least one load compensation unit, between the at least one output terminal and the at least one gate line, and electrically connected with the at least one gate line and the at least one output terminal;

    wherein the display panel comprises a display area and a non-display area surrounding the display area, the plurality of gate lines, the plurality of data lines, and the voltage supply wires are in the display area, and the gate driving circuit, the at least one load compensation unit, and the voltage supply terminal are in the non-display area;

    in a direction from the voltage supply terminal to the voltage supply wires, the farther a load compensation unit is away from the voltage supply terminal, the larger compensation load value of the load compensation unit is; and

    the at least one load compensation unit is configured to adjust charging time of pixels by controlling the gate lines, to make brightness of a plurality of areas of a display screen uniform.
