Abstract

The invention discloses a display panel and a display device, and belongs to the technical field of display. The display panel comprises a display area and a peripheral non-display area; the display area comprises gate lines, data lines and a plurality of sub-pixels; the display area comprises a main display area and an auxiliary display area; the number of sub-pixels of each pixel row in the maindisplay area is larger than the number of sub-pixels of each pixel row in the auxiliary display area; the non-display area comprises a light emitting circuit, and the light emitting circuit comprisesa plurality of cascaded light emitting units; the sub-pixels in n pixel rows in the main display area are electrically connected with the same light emitting unit, and the sub-pixels in at least n+1pixel rows of the auxiliary display area are electrically connected with the same light emitting unit, wherein n is a positive integer; each sub-pixel comprises a pixel driving circuit, each pixel driving circuit comprises a light emitting control signal end, and the light emitting control signal end of each sub-pixel is electrically connected with the corresponding light emitting unit. Compared with the prior art, the narrow bezel design of the display panel is facilitated, the brightness uniformity of the main display area and the auxiliary display area is improved, and the display quality is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more particularly, to a display panel and a display device. Background technique [0002] With the development of display technology, the traditional rectangular display panel can no longer meet the diverse usage requirements of users. [0003] Please refer to figure 1 , figure 1 The partial structure at the corner of the special-shaped display panel is illustrated. A special-shaped display panel provided in the prior art includes a display area aa and a non-display area na. 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 arranged in the non-display area na, and the light-emitting circuit provides a light-emitting driving signal for the pixel driving circuit in the pixel p. The light emitting circuit includes a plurality of cascaded light emitting units e, and...
