[0017] An embodiment of the present disclosure provides a display panel, including a plurality of pixel units 100 and a plurality of pixel drive circuits. Each of the pixel units 100 includes a plurality of pixels 1001. At least one of the pixel drive circuits includes two different types of transistors, and at least one of the pixel drive circuits is configured to respond to a light-emitting control signal EM to simultaneously drive two adjacent sub-pixels in the same pixel 1001 or two adjacent sub-pixels in two adjacent pixels 1001. Therefore, a display uniformity is increased, and a display quality of the display panel is improved.

[0018] Specifically, please refer to FIG. 1 and FIG. 2A to FIG. 2G, one of the plurality of pixels 1001 includes a first pixel 101. The first pixel 101 includes a first sub-pixel 1011 and a second sub-pixel 1012 adjacent to the first sub-pixel 1011. At least one of the pixel drive circuits is configured to respond to the light-emitting control signal EM to simultaneously drive the first sub-pixel 1011 and the second sub-pixel 1012. Thus, the display panel employs one pixel drive circuit to control the first sub-pixel 1011 and the second sub-pixel 1012 to emit light simultaneously, which increases the display uniformity and improves the display quality of the display panel.

[0019] Furthermore, the pixel drive circuit is also configured to drive two adjacent sub-pixels in two adjacent pixels 1001. Specifically, please refer to FIG. 2B to FIG. 2G, the plurality of pixels 1001 include a first pixel 101 and a second pixel 102 that are adjacent to each other in a first direction (i.e., a y-direction).
