The prior art provides a special-shaped display panel, which includes a display area aa and a non-display area na, where the display area aa includes a section of a special-shaped edge y, and the special-shaped edge y is located at a corner of the display panel. A light-emitting circuit is provided in the non-display area na, and the light-emitting circuit supplies a light-emission drive signal to a pixel drive circuit in the pixel p. The light emitting circuit includes a plurality of cascade-connected light emitting cells e, one of which supplies a light emitting drive signal to the pixel drive circuit of one row of pixels p. The non-display area na at the corner is irregular in shape, and the excessive light-emitting units e are integrated in the non-display area na at the corner, which is not favorable for narrowing the frame at the corner.
In addition, the number of pixels p in the pixel row adjacent to the shaped edge y is smaller than that in the conventional pixel row. When the light-emitting driving signals provided by the light-emitting units e are the same, the load of the pixel driving circuit in each pixel row is different due to the different number of pixels p in each pixel row, which causes non-uniform brightness in each pixel row and reduces the display quality.

It is understood that the electrical signal output by the second light emitting unit may refer to fig. 9.
In this embodiment, since the first light-emitting unit EU1A is electrically connected to the 2 pixel rows P0, and the first light-emitting unit EU1B is electrically connected to only 1 pixel row P0, the pulse widths of the clock signals on the first main clock signal line CK1 and the first auxiliary clock signal line XCK1 are set to be wider, so that the interval between the light-emitting signals output by two adjacent first light-emitting units EU1A is longer, and when the refresh of all the 2 pixel rows P0 electrically connected to the first light-emitting unit EU1A is completed, the refresh of the subsequent pixel rows is performed.
