Abstract

This application provides a display panel and an electronic device. A display region of the display panel is divided into at least two pixel regions. The pixel region includes at least two subpixels. The display region includes a first display region and a second display region. Subpixel density of the first display region is less than that of the second display region. In the first display region, at least some adjacent pixel regions have different structures. By changing structures of at least some pixel regions in the first display region, an arrangement rule of structures in pixel regions in the first display region is changed to some extent, and form a long-period diffraction grating or an aperiodic diffraction grating, so that a diffraction phenomenon caused by light passing through the display panel can be mitigated.

1 - 12 . (canceled)

13 . A display panel comprising:
a display area comprising a first display region and a second display region, the first display region corresponding to a location of a functional element disposed beneath the display area; the first display region comprising a plurality of repetition units arranged in an array, each repetition unit comprising a first pixel region and a second pixel region, wherein a structure of the first pixel region is different from a structure of the second pixel region.

14 . The display panel of claim 13 , wherein the first pixel region comprises a first subpixel for emitting red light, a second subpixel for emitting blue light, and a third subpixel for emitting green light.

15 . The display panel of claim 14 , wherein the second pixel region comprises a fourth subpixel for emitting red light, a fifth subpixel for emitting blue light, and a sixth subpixel for emitting green light.

16 . The display panel of claim 15 , wherein the first pixel region and the second pixel region each comprises four subpixels.

17 . The display panel of claim 16 , wherein an arrangement of subpixels of the first pixel region is different from an arrangement of subpixels of the second pixel region.

18 . The display panel of claim 17 , wherein one subpixel corresponds to one light emitting region, wherein the arrangement of subpixels of the first pixel region being different from the arrangement of subpixels of the second pixel region further comprises at least one of the following:
the light emitting regions have different shapes; the light emitting regions have different area sizes; adjacent light emitting regions have different relative locations; adjacent light emitting regions have different spacing distances; and oblique angles of the light emitting regions relative to a same edge of the display panel are different.

19 . The display panel of claim 14 , wherein shapes of the first subpixel, the second subpixel and the third subpixel are different.

20 . The display panel of claim 13 , wherein a light shielding structure is configured in the display panel by adding a film layer structure to the display panel, the light shielding structure corresponding to a corresponding pixel region.

21 . The display panel of claim 20 , wherein the light shielding structure is configured to change a shape of a transparent region in a non-light-emitting region corresponding to the corresponding pixel region, and change a shape of a diffraction grating formed by the corresponding pixel region.

22 . The display panel of claim 21 , wherein a material for fabricating the light shielding structure comprises a metal.

23 . The display panel of claim 13 , wherein the second display region half-surrounds the first display region.

24 . The display panel of claim 13 , wherein adjacent pixel regions in the second display region have a same structure.

25 . The display panel of claim 13 , wherein a subpixel density of the first display region is less than a subpixel density of the second display region.

26 . The display panel of claim 16 , wherein some of the subpixels in the first pixel region are the same shape, and/or some of the subpixels in the second pixel region are the same shape.

27 . An electronic device comprising;
a display panel and an optical element, wherein the optical element is located under the display panel, wherein a display area of the display panel comprises a first display region and a second display region, the first display region corresponding to a location of the optical element; the first display region comprising a plurality of repetition units arranged in an array, each repetition unit comprising a first pixel region and a second pixel region, wherein a structure of the first pixel region is different from a structure of the second pixel region.

28 . The electronic device of claim 27 , wherein the first pixel region and the second pixel region each comprises four subpixels.

29 . The electronic device of claim 28 , wherein an arrangement of subpixels of the first pixel region is different from an arrangement of subpixels of the second pixel region.

30 . The electronic device of claim 29 , wherein one subpixel corresponds to one light emitting region, and the arrangement of the subpixels of the first pixel region is different from the arrangement of the subpixels of the second pixel region further comprises at least one of the following:
the light emitting regions have different shapes; the light emitting regions have different area sizes; adjacent light emitting regions have different relative locations; adjacent light emitting regions have different spacing distances; and oblique angles of the light emitting regions relative to a same edge of the display panel are different.

31 . The electronic device of claim 27 , wherein a light shielding structure is configured in the display panel by adding a film layer structure to the display panel, the light shielding structure corresponding to a corresponding pixel region.

32 . The electronic device of claim 31 , wherein light shielding structure is configured to change a shape of a transparent region in a non-light-emitting region corresponding to the corresponding pixel region, and change a shape of a diffraction grating formed by the corresponding pixel region.
