Abstract

A display panel and a display apparatus are provided. The display panel comprises a display region including an irregular-shaped display area, and a non-display region adjacent to the display region. The irregular-shaped display area includes a plurality of pixels arranged in an array. Adjacent pixel rows and/or adjacent pixel columns are indented by at least one pixel at a periphery of the irregular-shaped display area. The at least one indented pixel between the adjacent pixel rows and/or the adjacent pixel columns is a misaligned pixel. The irregular-shaped display area includes a transition area, and the transition area at least includes the misaligned pixel. A maximum display brightness of pixels in the transition area is smaller than a maximum display brightness of pixels outside the transition area.

First claim

What is claimed is:

1. A display panel, comprising:
a display region including an irregular-shaped display area; and
a non-display region adjacent to the display region,
wherein:
the irregular-shaped display area includes a plurality of pixels arranged in an array;
adjacent pixel rows and/or adjacent pixel columns are indented by at least one pixel at a periphery of the irregular-shaped display area;
the at least one indented pixel between the adjacent pixel rows and/or the at least one indented pixel between the adjacent pixel columns is a misaligned pixel;
the irregular-shaped display area includes a transition area, and the transition area at least includes a plurality of misaligned pixels that are indented between the adjacent pixel rows and/or the adjacent pixel columns;
a maximum display brightness of a pixel disposed in the transition area is smaller than a maximum display brightness of a pixel disposed outside the transition area;
the transition area includes a first transition sub-area, a second transition sub-area, and a third transition sub-area;
a number of the misaligned pixels in each of a pixel row direction and a pixel column direction in the first transition sub-area is at most two;
a number of the misaligned pixels in each of a pixel row direction and a pixel column direction in the second transition sub-area is at least two;
a number of the misaligned pixels in each of a pixel row direction and a pixel column direction in the third transition sub-area is at least two;
the second transition sub-area and the third transition sub-area include only the misaligned pixels; and
the first transition sub-area includes the misaligned pixels and an adjacent pixel in a same pixel row or a same pixel column as the misaligned pixels.

2. The display panel according to claim 1 , wherein:
in the transition area, the maximum display brightness of the pixels in a same pixel row gradually increases in a direction moving away from the non-display region; and
in the transition area, the maximum display brightness of the pixels in a same pixel column gradually increases in the direction moving away from the non-display region.

3. The display panel according to claim 1 , wherein:
the second transition sub-area at least includes a first pixel row and a second pixel row;
in the second transition sub-area, the number of the misaligned pixels in the first pixel row is smaller than the number of the misaligned pixels in the second pixel row; and
a maximum display brightness difference between two adjacent misaligned pixels in the first pixel row is greater than a maximum display brightness difference between two adjacent misaligned pixels in the second pixel row.

4. The display panel according to claim 3 , wherein:
the maximum display brightness difference between any two adjacent misaligned pixels in the second pixel row is equal.

5. The display panel according to claim 1 , wherein:
the third transition sub-area at least includes a first pixel column and a second pixel column;
in the third transition sub-area, the number of the misaligned pixels in the first pixel column is smaller than the number of the misaligned pixels in the second pixel column; and
a maximum display brightness difference between two adjacent misaligned pixels in the first pixel column is greater than a maximum display brightness difference between two adjacent misaligned pixels in the second pixel column.

6. The display panel according to claim 5 , wherein:
the maximum display brightness difference between any two adjacent misaligned pixels in the second pixel column is equal.

7. The display panel according to claim 1 , wherein:
a portion of a contour edge of the irregular-shaped display area is a straight-line section parallel to neither a pixel row direction nor a pixel column direction; and
in the transition area, any two adjacent pixel rows have an equal number of misaligned pixels and/or any two adjacent pixel columns have an equal number of misaligned pixels.

8. The display panel according to claim 7 , wherein:
in the transition area, any two adjacent pixel rows each has one misaligned pixel, and any two adjacent pixel columns each has one misaligned pixel.

9. The display panel according to claim 8 , wherein:
a maximum display brightness of the misaligned pixels that are arranged along the straight-line section gradually decreases from a center of the straight-line section to both ends of the straight-line section.

10. The display panel according to claim 9 , wherein:
the maximum display brightness of the misaligned pixel at the center of the straight-line section is in a range approximately of 48 A/256 to 149 A/256, where A is the maximum display brightness of the pixel disposed outside the transition area of the irregular-shaped display area.

11. The display panel according to claim 8 , wherein:
a maximum display brightness of the misaligned pixels that are arranged along the straight-line section gradually increases from a center of the straight-line section to both ends of the straight-line section.

12. The display panel according to claim 11 , wherein:
the maximum display brightness of the misaligned pixel at the center of the straight-line section is in a range approximately of 88 A/256 to 166 A/256, where A is the maximum display brightness of the pixel disposed outside the transition area of the irregular-shaped display area.

13. The display panel according to claim 1 , wherein:
a portion of a contour edge of the irregular-shaped display area is an arc section that protrudes towards the non-display region.

14. The display panel according to claim 1 , wherein:
a portion of a contour edge of the irregular-shaped display area is an arc section that recesses towards the display region.

15. A display panel, comprising:
a display region including an irregular-shaped display area; and
a non-display region adjacent to the display region,
wherein:
the irregular-shaped display area includes a plurality of pixels arranged in an array;
adjacent pixel rows and/or adjacent pixel columns are indented by at least one pixel at a periphery of the irregular-shaped display area;
the at least one indented pixel between the adjacent pixel rows and/or the at least one indented pixel between the adjacent pixel columns is a misaligned pixel;
the irregular-shaped display area includes a transition area, and the transition area at least includes a plurality of misaligned pixels that are indented between the adjacent pixel rows and/or the adjacent pixel columns;
a maximum display brightness of a pixel disposed in the transition area is smaller than a maximum display brightness of a pixel disposed outside the transition area;
a portion of a contour edge of the irregular-shaped display area is an arc section that protrudes towards the non-display region;
