1. A display panel, comprising:
a display area; and a bezel area surrounding the display area, wherein the display area comprises: a plurality of sub-pixels arranged in an array, and scanning lines connected to rows of the sub-pixels respectively;
the display area comprises: a first display sub-area, and a second display sub-area, wherein the second display sub-area is arranged between the bezel area and the first display sub-area;
distribution density of sub-pixels in the second display sub-area is lower than distribution density of sub-pixels in the first display sub-area;
wherein a sub-pixel row having a greatest quantity of sub-pixels in the display panel is taken as a reference sub-pixel row, the quantity of sub-pixels in the reference sub-pixel row is taken as a reference value, sub-pixel rows each having a quantity of sub-pixels smaller than the reference value are taken as compensation sub-pixel rows, and scanning lines connected to the compensation sub-pixel rows respectively are taken as first scanning lines; and
the display panel is provided with load compensation units corresponding to at least part of the first scanning lines, and the load compensation units are arranged in the second display sub-area;
wherein the display panel further comprises shift register units which are connected to the scanning lines respectively; and wherein shift register units connected to the first scanning lines are arranged only in the second display sub-area; and
wherein each of the load compensation units comprises a compensation capacitor structure and a compensation resistor structure, and the compensation capacitor structure comprises a plurality of capacitors which are connected in parallel.
