a first sub-pixel density distribution area arranged corresponding to the first display area, wherein the first sub-pixel density distribution area comprises a plurality of first sub-pixels and a plurality of first virtual sub-pixels and one of the plurality of first virtual sub-pixels is arranged between two adjacent first sub-pixels,
a second sub-pixel density distribution area arranged corresponding to the second display area, and

a third sub-pixel density distribution area arranged on at least one of the first display area and the second display area and adjacent to a boundary between the first display area and the second display area; wherein a first sub-pixel distribution density corresponding to the first sub-pixel density distribution area is less than a third sub-pixel distribution density corresponding to the third sub-pixel density distribution area, and the third sub-pixel distribution density is less than a second sub-pixel distribution density corresponding to the second sub-pixel density distribution area.

2. The display panel of claim 1 , wherein the second sub-pixel density distribution area comprises a plurality of second sub-pixels, the third sub-pixel density distribution area comprises a plurality of third sub-pixels; in a width direction of the display panel, the third sub-pixel density distribution area is disposed between the first sub-pixel density distribution area and the second sub-pixel density distribution area.

3. The display panel of claim 2 , wherein a column of the third sub-pixels is arranged in a direction perpendicular to the width direction.

4. The display panel of claim 2 , further comprising:
a plurality of second virtual sub-pixels disposed in the third sub-pixel density distribution area; wherein a first pixel arrangement formed by the first sub-pixels and the first virtual sub-pixels is the same as a second pixel arrangement formed by the second sub-pixels;
a third pixel arrangement formed by the third sub-pixels and the second virtual sub-pixels is the same as the second pixel arrangement.

5. The display panel of claim 4 , wherein in the third pixel arrangement, one of the plurality of second virtual sub-pixels is arranged between two adjacent third sub-pixels.

6. The display panel of claim 4 , wherein for the first sub-pixels in adjacent two columns, the first sub-pixels emitting a same color are in different rows; or
for the first sub-pixels in adjacent two rows, the first sub-pixels emitting a same color are in different columns.

7. The display panel of claim 4 , wherein the first sub-pixels in a same row or a same column emit same colors; and/or
the third sub-pixels emit a color different from colors emitted by both the first sub-pixels and the second sub-pixels adjacent to the third sub-pixels.

8. The display panel of claim 2 , further comprising:
a first pixel circuit disposed in the second display area and electrically connected with the first sub-pixels to drive the first sub-pixels to display; and
a second pixel circuit disposed in the second display area and electrically connected with both the second sub-pixels and the third sub-pixels to drive the second sub-pixels and the third sub-pixels to display.

9. The display panel of claim 2 , wherein each of the first sub-pixels comprises a first electrode, a light-emitting structure and a second electrode that are stacked in sequence.

10. The display panel of claim 9 , wherein a projection of the first electrode in a direction perpendicular to the display panel comprises one second graphic unit or two or more second graphic units connected together, and the second graphic unit comprises at least one selected from a group comprising a round shape, an oval shape, a dumb-bell shape, a gourd shape and a rectangle shape.

11. The display panel of claim 9 , wherein the first electrode of the first display area is a light-transmitting electrode.

12. The display panel of claim 9 , wherein the first electrode of the first display area is a reflective electrode.

13. The display panel of claim 9 , wherein the first electrode of the first display area comprises at least one of an indium tin oxide layer, an indium zinc oxide layer, and a magnesium-silver alloy layer.

14. The display panel of claim 9 , wherein a projection of the light-emitting structure in a direction perpendicular to the display panel comprise one first graphic unit or two or more first graphic units spliced together, and the first graphic unit comprises at least one selected from a group comprising a round shape, an oval shape, a dumb-bell shape, a gourd shape and a rectangle shape.

15. A display panel, having a first display area and a second display area, a transmittance of the first display area being greater than a transmittance of the second display area, the display panel comprising:
an array substrate;
a light-emitting layer arranged on the array substrate and comprising a first sub-pixel density distribution area arranged corresponding to the first display area, a second sub-pixel density distribution area arranged corresponding to the second display area, and a third sub-pixel density distribution area arranged on at least one of the first display area and the second display area and adjacent to a boundary between the first display area and the second display area;
wherein a first sub-pixel distribution density corresponding to the first sub-pixel density distribution area is less than a third sub-pixel distribution density corresponding to the third sub-pixel density distribution area, and the third sub-pixel distribution density is less than a second sub-pixel distribution density corresponding to the second sub-pixel density distribution area;
