CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims benefit of the filing dates of Chinese Patent Application No. 201711341677.1 filed on Dec. 14, 2017 and Chinese Patent Application No. 201711313230.3 filed on Dec. 12, 2017, the disclosure of which is hereby incorporated in its entirety by reference.

TECHNICAL FIELD

This disclosure relates to display technology, in particular, to a display panel and a display apparatus.

BACKGROUND

With the development of display screen technology, more and more display screens adopt a design with round corners, that is, four corners of a display screen are arc-shaped.

For a display screen with round corners, sub-pixels are arranged in rows and columns. Thus, the sub-pixels cannot fully fill the round corners of the display screen. As such, sawtooth-shaped notches exist, thereby forming sawteeth at the four corners of the display screen. Taking liquid crystal display (LCD) as an example, the method of solving the sawteeth on the four corners of the display screen of the LCD with the round corners in the related art is described as follows. The openings of the black matrixes which are located at four corners of the display screen are designed to be relatively small. Each sub-pixel corresponds to one opening. The smaller the area of the opening corresponding to the sub-pixel, the smaller the light transmittance of the sub-pixel. As such, the brightness of the four corners of the display screen is low. Therefore, the sawteeth at the four corners of the display screen are weakened.

However, when the above method is adopted to eliminate the sawteeth, the distance among the sub-pixels at the four corners of the display screen increases. As such, the distance among the sub-pixels of colors red (R), green (G), blue (B) in the same pixel is so large that what a user sees is not just one point, but three independent points. Meanwhile, a user can obviously notice dark dots caused by the black matrixes between the sub-pixels. Therefore, the bright dark dots distributed at intervals can be seen on the display screen.

BRIEF SUMMARY

Accordingly, one example of the present disclosure is a display panel. The display panel may include a first light shielding layer in a display region and a second light shielding layer in the display region. The first light shielding layer may include a plurality of first openings, and the second light shielding layer may include a plurality of second openings. The display region may include a middle display region and a periphery display region. An area of each of the plurality of the first openings in the periphery display region may be smaller than an area of each of the plurality of the first openings in the middle display region. The area of each of the plurality of the first openings in the periphery display region may be smaller than an area of each of the plurality of the second openings in the periphery display region. Each of the plurality of the second openings may have the same area.

Areas of the plurality of the first openings in the periphery display region may gradually decrease along a direction from a border of the middle display region and the periphery display region to an outer edge of the periphery display region. The areas of the plurality of the first openings along the direction from the border of the middle display region and the periphery display region to the outer edge of the periphery display region may decrease at a constant ratio or by a constant value.

In one embodiment, the display panel may be divided into a plurality of regions from a border of the middle display region and the periphery display region to an edge of the display panel, areas of the first openings in different regions may be different, and areas of the first openings in the same region may be the same.

The display panel may include an array substrate and a color film substrate, and the first light shielding layer may be on the array substrate, and the second light shielding layer may be on the color film substrate.

An orthographic projection of each of the plurality of the first openings on the second light shielding layer may be located inside one of the plurality of the second openings. In one embodiment, a center of an orthographic projection of each of the plurality of the first openings on the second light shielding layer coincides with a center of the one of the plurality of second openings.

The first light shielding layer may be made of a non-transparent metal. Material of the first light shielding layer may be the same as material of electrodes in the display panel. In one embodiment, the first light shielding layer is made of molybdenum. The second light shielding layer may be a black matrix layer. Each of the second openings in the black matrix layer may be filled with a color film layer. The color film layer may be a red color film layer, a green color film layer, or a blue color film layer. A shape of each of the plurality of the first openings may be the same as a shape of each of the plurality of the second openings. The shape of each of the plurality of the first openings may be rectangular. A thickness of the first light shielding layer may range from approximately 400 Å to approximately 600 Å. The display panel may be a LCD display panel.

Another example of the present disclosure is a display apparatus. The display apparatus may include the display panel according to one embodiment of the present disclosure.
