Abstract

A display device including a display panel. The display panel includes a display region and a non-display region surrounding the display region. The display region includes a first pixel region, the non-display region includes a second pixel region, and the first pixel region and the second pixel region together form a pixel region. The first pixel region and the second pixel region each includes a plurality of pixels. The display device also includes a cover window disposed on a light-emitting side of the display panel. The cover window includes a viewable region and a light-shielding region surrounding the viewable region, and the light-shielding region is disposed with a light-shielding material. The area of the pixel region is larger than the area of the viewable region, the first pixel region is arranged opposite to the viewable region, and the second pixel region is arranged opposite to the light-shielding region.

First claim

What is claimed is:

1. A display device, comprising:
a display panel, including a display region and a non-display region surrounding the display region, wherein the display panel includes a bendable region and a non-bendable region, the display region includes a first pixel region, the non-display region includes a second pixel region, the first pixel region and the second pixel region together form a pixel region, and the first pixel region and the second pixel region each includes a plurality of pixels; and
a cover window, disposed on a light-emitting side of the display panel, wherein the cover window includes a viewable region and a light-shielding region surrounding the viewable region, and the light-shielding region is disposed with a light-shielding material,
wherein at least a portion of the light-shielding region and at least a portion of the second pixel region are in the bendable region, an area of the pixel region is larger than an area of the viewable region, the first pixel region is arranged opposite to the viewable region, and the second pixel region is arranged opposite to the light-shielding region.

2. The display device according to claim 1 , wherein:
along a first direction, a smallest distance between an edge of the first pixel region and an edge of the light-shielding region is smaller than or equal to a distance between two adjacent pixels, wherein the first direction is in a plane where the plurality of pixels are deposed and perpendicular to an edge of the light-shielding region.

3. The display device according to claim 2 , wherein:
along the first direction, a width of the second pixel region is larger than or equal to approximately 50 μm.

4. The display device according to claim 1 , wherein:
the pixel region has a rectangular or circular shape; and
the viewable region has a rectangular or circular shape.

5. The display device according to claim 1 , wherein:
at least one of the pixel region and the viewable region is arc-shaped at corners between adjacent edges.

6. The display device according to claim 1 , wherein:
the pixel region has a rectangular shape; and
the viewable region is arc-shaped at corners or has a circular shape.

7. The display device according to claim 1 , wherein:
the non-display region extends into the display region from at least one edge of the display region to form a second non-display region, wherein,
the second non-display region divides the display region into a first display region and a second display region, and
the second non-display region and the second display region are located on a same side of the first display region.

8. The display device according to claim 1 , wherein:
the plurality of pixels in the first pixel region are arranged in a same manner as the plurality of pixels in the second pixel region.

9. The display device according to claim 1 , wherein:
the display panel is an organic light-emitting diode (OLED) display panel or a liquid crystal display (LCD) panel.

10. The display device according to claim 1 , wherein:
the plurality of pixels in the second pixel region are in a default black state.

11. A display device, comprising:
a display panel, including a display region and a non-display region surrounding the display region, wherein the display panel includes a bendable region and a non-bendable region, the display region includes a first pixel region, the non-display region includes a second pixel region, the first pixel region and the second pixel region together form a pixel region, and the first pixel region and the second pixel region each includes a plurality of pixels; and
a cover window, disposed on a light-emitting side of the display panel, wherein the cover window includes a viewable region and a light-shielding region surrounding the viewable region, and the light-shielding region is disposed with a light-shielding material,
wherein:
at least a portion of the light-shielding region is in the bendable region, an area of the pixel region is larger than an area of the viewable region, the first pixel region is arranged opposite to the viewable region, and the second pixel region is arranged opposite to the light-shielding region
an interface between the display region and the non-display region coplanar with an interface between the first pixel region and the second pixel region;
the light-shielding region is completely located in the bendable region;
at least a portion of the display region is located in the bendable region; and
at least a portion of the non-display region is in the bendable region.

12. The display device according to claim 11 , wherein:
at least a portion of the second pixel region is in the bendable region.

13. A display device, comprising:
a display panel, including a display region and a non-display region surrounding the display region,
wherein:
the display region includes a first pixel region, the non-display region includes a second pixel region, and the first pixel region and the second pixel region together form a pixel region,
the first pixel region and the second pixel region each includes a plurality of pixels,
the plurality of pixels in the second pixel region are in a default black state, and

wherein the display panel includes a bendable region and a non-bendable region, at least a portion of the light-shielding region and at least a portion of the second pixel region are in the bendable region, and the non-display region is in the bendable region.

14. The display device according to claim 13 , wherein:
the display region includes a third display region and a fourth display region;
the third display region is in the non-bendable region; and
