Detailed Description
Embodiments of the present application will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the application are shown, and in which it is to be understood that the embodiments described are merely illustrative of some, but not all, of the embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
As described in the background art, a display panel includes a display area and a bezel area surrounding the display area. In a conventional display panel, when an image is not displayed in a state of a screen, a color difference exists between a display area and a non-display area. This problem is particularly noticeable in an electronic paper display panel that displays black and white.
The electronic paper display panel of black and white display receives external light through microcapsules in electronic ink in a display area due to its light emitting characteristic, and then reflects the external light to perform display. For example, for an electronic paper display panel that can display a black-and-white image, the microcapsules include a white side and a black side that are charged, and the desired black-and-white image can be acquired by controlling the white side and the black side of the microcapsules to face the display side. The microcapsule displays black and white images, and has the advantages of low power consumption, light weight, easy design of light and thin display panel, free shape design, etc.
However, due to the characteristics of the electronic paper display panel, in a breath-hold state where no image is displayed, it is necessary that the black surfaces of all the microcapsules face the display side, and absorb visible light, so that the entire display area appears black. However, the black color of the microcapsule has a limited amount of absorption of external light, and some light is still reflected, so that the luminance (L value) of the display area is higher than that of the non-display area, and the luminance of the display area is as high as 30 or more. In general, the display area presents a grayish appearance, while the non-display area is generally shielded from light by using black ink, the brightness of the black ink is generally 27-29, and the display area and the non-display area have large color difference, so that the display area and the non-display area have obvious visual difference in appearance. In order to realize that the appearances of the display area and the non-display area in a screen breathing state meet the same condition so as to reduce the color difference between the display area and the non-display area, one implementation mode is to reduce the brightness of the display area, but the brightness of the display area of the electronic paper display panel is not easy to regulate and control and is not easy to reduce and reduce, and the display brightness of the electronic paper display panel is low, so that the display brightness is low, and the display performance is seriously influenced.
In order to solve the above problem, an embodiment of the present application provides a display panel, including:
the display module is provided with a display area and a non-display area surrounding the display area;
the cover plate is provided with a light shielding layer in a region opposite to the non-display region, and the light shielding layer is positioned on one side, facing the display module, of the cover plate;
the micro structure is arranged between the light shielding layer and the cover plate, and the micro structure is used for enabling the display area and the non-display area to meet the same chromaticity condition when the display panel is in a screen state.
According to the display panel, the display area and the non-display area can meet the same chromaticity condition when the display panel is in the breath-hold state through the microstructures on the cover plate, so that the problem of color difference between the display area and the non-display area when the display panel is in the breath-hold state without displaying images is reduced or even eliminated.
It should be noted that, in the embodiment of the present application, the problem of color difference between the display area and the non-display area in the screen saver state is more prominent based on the characteristics of the electronic paper display panel, so that the problem of color difference between the display area and the non-display area in the screen saver state is obviously solved by taking the electronic paper display panel as an example, and the display panel having the problem is not limited to the electronic paper display panel, and may also be other types of display panels such as LCD, OLED, and the like.
In order to make the aforementioned objects, features and advantages of the present application more comprehensible, the present application is described in further detail with reference to the accompanying drawings and the detailed description.

a cover plate 12, wherein a region of the cover plate 12 opposite to the non-display region 111 is provided with a light shielding layer 13, and the light shielding layer 13 is positioned on one side of the cover plate 12 facing the display module 11;
the microstructure 14 is arranged between the light shielding layer 13 and the cover plate 12, and the microstructure 14 is used for enabling the display area 111 and the non-display area 112 to satisfy the same chromaticity condition when the display panel 100 is in a breath-hold state. The display area 111 and the non-display area 112 satisfying the same chromaticity condition include: in a breath-holding state where no image is displayed, the chromaticity and brightness of the display region 111 and the brightness of the non-display region 112 are the same or approximately the same, so that the two regions have the same or similar appearance display effect.

The microstructures 14 have the same shape and the same arrangement density, so as to ensure that different areas in the non-display area 112 satisfy the same chromaticity condition. The microstructures 14 can increase the diffuse reflection effect of the non-display area 112, so as to increase the reflection of the external light, thereby realizing the integrated color of the display area 111 and the non-display area 112.
In the conventional display panel, due to the difference in film layer structures between the display region and the non-display region, the display region 111 and the non-display region 112 have a color difference in a state of a screen without displaying an image, and the display region 111 and the non-display region 112 have a difference in appearance. In the technical solution of the embodiment of the application, the display panel 100 can reduce or even eliminate the color difference between the display area 111 and the non-display area 112 in the state of not displaying the image and reduce the degree of the appearance difference between the two, so that the two have the same or similar appearance display effect, thereby forming an effect of visually integrating the colors in appearance.

The light-transmitting protrusions may increase a diffuse reflection effect of the non-display area 112, thereby increasing reflection of external light, thereby implementing an integrated color of the display area 111 and the non-display area 112.
Optionally, the light-transmitting protrusion may be a cone protrusion, a cylinder protrusion, a sphere protrusion, a prism protrusion, or other three-dimensional geometric protrusion structures, and the specific shape structure of the light-transmitting protrusion is not limited in this embodiment of the application. In order to ensure that different areas in the non-display area 112 satisfy the same adjustment of chromaticity, the transparent protrusions are arranged in the same shape and are uniformly distributed.
