For example, as shown in FIG. 2 and FIG. 10, the display panel further includes a plurality of pixel units 140 located in the display region 200 of the base substrate 10. The display region 200 includes a first pixel density region 210 and a second pixel density region 220, and the pixel density (Pixels Per Inch, PPI) of the plurality of pixel units 140 located in the first pixel density region 210 is greater than the pixel density of the plurality of pixel units 140 located in the second pixel density region 220, that is, the first pixel density region 210 can be a high pixel density region and the second pixel density region 220 can be a low pixel density region. The transparent display region 221 is located in the second pixel density region 220, that is, the transparent display region 221 is a part of the low pixel density region.

In the case where the camera is located at the non-display side of the display panel, the camera performs imaging by acquiring external light signals passing through the transparent display region. In the embodiment of the disclosure, the PPI of the transparent display region is designed to be lower than the PPI of the first pixel density region, so that the light transmittance of the transparent display region can be increased while taking account of display, so as to realize the photographing function.
