For example, as shown in FIG. 1, 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.

For example, the first pixel density region 210 can also be referred to as a normal pixel region, the second pixel density region 220 can also be referred to as an abnormal pixel region, the light emitting area of pixel units in the second pixel density region 220 can be ? of the light emitting area of pixel units in the first pixel density region 210, and the PPI of pixel units in the second pixel density region 220 can be ? of the PPI of pixel units in the first pixel density region 210.
