For the OLED display device, it has advantages of self-luminescence, low power consumption, no liquid crystal flowing layer, etc., and thus is widely used in flexible display devices. The structure of the existing flexible OLED display device generally includes a thin film transistor array substrate based on a flexible substrate, a light emitting layer, an encapsulation layer based on a multi-layer thin film, and a circular polarizer. In the film structure, especially for the top-emitting OLED device, the circular polarizer arranged therein can reduce the reflectivity of ambient light, and also can increase the contrast of the display panel and improve the readability of the OLED in outdoor environment. However, when light passes through the circular polarizer, about 58% of the light is lost, thereby reducing the display effect of the display panel.

It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. 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 invention.
In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", and the like, indicate orientations and positional relationships based on those shown in the drawings, and are used only for convenience of description and simplicity of description, and do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention. Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
With the continuous development of display panel manufacturing technology, people have higher and higher requirements on the display performance and the panel quality of the display panel. It is desirable that not only the overall thickness of the display panel be smaller and smaller, but also the display panel have a high display effect at the time of normal display.
As shown in fig. 1, fig. 1 is a schematic diagram of a film structure of a display panel provided in the prior art. Specifically, the display panel includes a substrate 100, an encapsulation layer 101, and a black matrix layer 102. In order to improve the display effect of the display panel, in the prior art, a color film is used to replace a polarizer structure. A specific encapsulation layer 101 is disposed on the substrate 100, and a black matrix layer 102 is disposed on the encapsulation layer 101. Meanwhile, the black matrix layer 102 is provided as a grid structure, and the color filter 104 is provided in the light transmission region 103 formed by the grid structure, when the display panel displays a picture, light is emitted by the light emitting layer provided in the substrate 100 and passes through the color filter 104 in the light transmission region 103 in sequence, so as to realize display effects of different colors.
However, the upper surface of the black matrix layer 102 provided in the prior art is relatively flat, and when external light enters the display panel, the surface of the flat black matrix layer 102 substantially acts as a mirror surface, so that when a user observes from outside the screen, a large degree of reflection occurs, and the display and use effects of the display panel are affected.
The embodiment of the invention provides a color filter and a preparation method of the color filter. The film layer structure in the display panel is improved, so that the display effect and the display quality of the display panel are effectively improved.
Specifically, as shown in fig. 2, fig. 2 is a schematic diagram of a film structure of the optical filter provided in the embodiment of the present invention. The optical filter in the display panel in the embodiment of the present invention includes a black matrix layer 200 and a color filter layer 201. Specifically, the black matrix layer 200 is distributed in a grid shape, and the black matrix layer 200 includes a light shielding region 203 and a light transmitting region 202. The light-shielding region 203 may be distributed at one side of the light-transmitting region 202. In the embodiment of the present invention, when the black matrix layer 200 is disposed, the black matrix layer 200 further includes a microstructure. The microstructures are arranged on the black matrix layer 200, so that light rays are effectively absorbed, and the display effect of the display panel is improved.
In the embodiment of the invention, the color filter layer 201 is correspondingly disposed in the light-transmitting area 202 formed by the black matrix layer 200, so that when light emitted from the light-emitting layer inside the display panel passes through the color filter layer 201, different color display effects can be realized.
In addition, the black matrix layer 200 and the color filter layer 201 are disposed in the same layer, that is, the thickness of the black matrix layer 200 is the same as that of the color filter layer 201, so as to ensure that the color filter of the display panel has a uniform thickness and the display panel has a high display effect. When external light is emitted to the surface of the black matrix layer 200 in the light shielding region 203, diffuse reflection is generated on the surface of the black matrix layer 200, so that light reflected by the surface of the black matrix layer 200 again is reduced, and the display effect and performance of the display panel are effectively improved.
Further, as shown in fig. 3, fig. 3 is a schematic structural diagram of another black matrix layer according to an embodiment of the present invention. In the embodiment of the present invention, when the corresponding black matrix layer 200 in the light shielding region is disposed, the black matrix layer 200 further includes a microstructure 303. The microstructures 303 are correspondingly disposed on the surface of the light-emitting side of the color filter layer.
The microstructure 303 in the embodiment of the present invention may be a convex-concave structure, such as a convex-concave microstructure like a micro-protrusion or a micro-depression. The microstructure 303 provided in the embodiment of the present invention is illustrated by taking a concave hole as an example, and other forms of microstructures have the same action principle as the concave hole in the embodiment of the present invention, and are not described in detail here.
The microstructure 303 includes a plurality of concave holes, and the plurality of concave holes may be connected with each other or not. Since the concave holes are formed on the surface of the black matrix layer 200, a plurality of concave structures are formed between the concave holes and the surface. When external light reaches the concave hole on the surface, the light can be reflected for multiple times in the concave hole, and then the light which is directly reflected from the surface of the black matrix layer 200 and enters the display panel is effectively reduced. Thereby effectively improving the display effect of the display panel.
Specifically, the recess hole in the embodiment of the present invention may include a first recess hole 3031 and a second recess hole 3032. The first recess holes 3031 are provided on the surface of the black matrix layer 200, and the second recess holes 3032 are provided inside the black matrix layer 200, for example, in the upper half area 302 of the black matrix layer 200. Specifically, in the embodiment of the present invention, when the second recessed hole 3032 is provided, the depth of the second recessed hole 3032 is not more than half of the thickness of the black matrix layer 200, so that the film performance of the black matrix layer 200 is effectively ensured.
In the embodiment of the present invention, the first recess 3031 and the second recess 3032 may be communicated. Specifically, a first recess 3031, which is a surface of the black matrix layer 200, may be communicated with a second recess 3032 near the first recess 3031. When light enters the first concave hole 3031, the light is reflected for multiple times in the first concave hole 3031 and is emitted to the second concave hole 3032, so that the light is further prevented from being directly emitted from the surface of the black matrix 200, and the effect of the black matrix layer 200 on the light is effectively improved.
In the embodiment of the invention, a plurality of dark holes 3033 are further included in the upper half area 302 of the black matrix layer 200 at positions far away from the first concave holes 3031, the dark holes 3033 are arranged inside the black matrix layer 200, and the dark holes 3033 can be communicated or not communicated with the first concave holes 3031 or the second concave holes 3032. Meanwhile, the concave hole structure provided in the black matrix layer 200 is not communicated with the lower surface of the black matrix layer 200, that is, the lower surface of the black matrix layer 200 is a flat lower surface, and the microstructure in the embodiment of the present invention is not provided.
Further, as shown in fig. 4, fig. 4 is a schematic propagation diagram of light in the embodiment of the present invention. When external light enters the black matrix layer 200, the microstructure 303 is arranged in the embodiment of the invention, and the microstructure 303 has a rough surface, so that on one hand, the microstructure 303 can increase the absorption of the reflected light, on the other hand, the microstructure 303 can further diffuse the incident light, and the situation of mirror reflection of the light is effectively reduced, thereby effectively improving the display contrast of the display panel under outdoor high light, and further effectively improving the display effect of the display panel.
The first light ray 34, the second light ray 35 and the third light ray 36 are taken as examples for explanation in the embodiment of the invention. The incident position of the first light ray 34 is in the first recess 3031, the incident position of the second light ray 35 is the flat surface of the black matrix layer, and the incident position of the third light ray 36 is in the second recess 3032. As can be seen from the reflected light of each light, the second light 35 is incident on the surface of the black matrix, so that the second light 35 can be directly reflected by the surface of the black matrix and then emitted out of the display panel again.
The incident positions of the first light ray 34 and the third light ray 36 are concave holes, so that the second light ray 34 and the third light ray 36 are further reflected on the inner wall of the concave holes. In the reflection process, the intensity of the light can be gradually reduced, or the light entering the concave hole can not be reflected out, and then the light reflected to the outside of the display panel is effectively reduced. Therefore, the microstructure 303 provided in the embodiment of the present invention effectively improves the effect of the color filter layer on light, and finally improves the display effect of the display panel.
Further, in the embodiment of the present invention, nanoparticles 301 are further disposed in the black matrix layer 200, wherein the nanoparticles 301 are disposed in a lower half area of the black matrix layer, as shown in fig. 3 by the nanoparticles 301. When the nanoparticles 301 are disposed, the nanoparticles 301 may be uniformly dispersed in the black matrix layer 200, or the nanoparticles 301 may be non-uniformly dispersed in the black matrix layer 200, and the specific distribution density may be set according to an actual product, so as to ensure that the black matrix layer has a recent effect.
Meanwhile, when the concave hole structure provided by the embodiment of the invention is arranged, the aperture of each concave hole can be set to be the same diameter, or a plurality of concave holes can be set to be different apertures, and the specific aperture size can be set according to the requirement of an actual product. In addition, the aperture of the concave hole provided by the embodiment of the invention is set between 100nm and 1um, so that each concave hole can effectively ensure that each concave hole has a good re-reflection effect on the entering light.
Further, the material of the nanoparticle 301 provided in the embodiment of the present invention may be polystyrene, and the polystyrene is configured in a spherical or elliptical structure, and the specific shape may be determined according to an actual product and the thickness of the black matrix layer. Also, the recesses in the present embodiment are formed 301 from the nanoparticles. When the concave hole structures are formed, the nano particles close to the surface layer of the black matrix layer are etched through an etching process, and each concave hole structure is formed in the area by the etched nano particles.
Meanwhile, the embodiment of the invention also provides a preparation method of the color filter layer. Specifically, as shown in fig. 5, fig. 5 is a method for manufacturing a color filter layer according to an embodiment of the present invention. When the color filter layer structure is prepared and formed, the method comprises the following steps:
b100: providing a substrate;
b101: preparing a black matrix layer on the substrate, and dispersing nano particles in the black matrix layer;
b102: removing the corresponding nano particles on the surface layer on the light emergent side of the black matrix layer, and forming a microstructure;
b103: and arranging a color filter layer in the light-transmitting area of the black matrix layer.
Specifically, during fabrication, a substrate is provided. As shown in fig. 6, fig. 6 is a schematic view of a film structure corresponding to a process flow of the display panel according to the embodiment of the present invention. In the embodiment of the present invention, the substrate may include a light emitting layer 500 and an encapsulation layer 501. Wherein the encapsulation layer 501 is disposed on the light emitting layer 500, and the light emitting layer 500 is disposed at a position corresponding to the light transmission region 202 of the display panel. So that the light emitted from the light-emitting layer 500 of the display panel can pass through the light-transmitting region 202 for the purpose of light-emitting display.
In the embodiment of the present invention, the black matrix layer 200 is disposed on the encapsulation layer 501. When the black matrix layer 200 is disposed, the black matrix layer 200 is correspondingly disposed in a position corresponding to the light shielding region 203 of the display panel, thereby achieving a light shielding effect of the black matrix layer 200. The black matrix layer 200 provided in the embodiment of the present invention is in a grid-like distribution.
Further, at the same time as the black matrix layer 200 is provided, the nanoparticles 301 are also provided in the black matrix layer 200. The selected nanoparticles 301 may be directly dispersed in the black matrix layer 200, for example, uniformly dispersed in the black matrix layer 200, and after the dispersion is completed, a plurality of nanoparticles 301 may be formed at different positions of the black matrix layer 200.
The nano particles can be selected from spherical polystyrene particles, and the size range of the polystyrene particles is between 100nm and 1um, so that certain influence on the performance of the black matrix layer 200 is avoided. After the nanoparticles 301 are disposed, the black matrix layer 200 is dried and formed into a film, and the following preparation process is continued.
The black matrix layer 200 is etched, and the etching parameters are controlled during the etching process, so that the nanoparticles 301 near the surface layer of the black matrix layer 200 are etched away during the etching process. Thus, since the nanoparticles 301 near the surface layer are etched away, a corresponding small hole is formed at a position corresponding to each nanoparticle 301 after the removal, and the size and shape of the hole are the same as those of the originally arranged nanoparticles 301. After the etching is completed, a plurality of concave holes, such as the microstructure of the first concave hole 3031, are formed on the surface of the black matrix layer 200 or in the vicinity of the surface layer. Specifically, as shown in fig. 7, fig. 7 is a schematic diagram of a film structure corresponding to an etching process of the display panel according to the embodiment of the present invention.
Further, as shown in fig. 8, fig. 8 is a schematic view of a film structure corresponding to another manufacturing process of the display panel according to the embodiment of the present invention. After the black matrix layer 200 is completely disposed, other film layers are continuously disposed in the light-transmitting region 202. In the embodiment of the invention, the color filter layer 801 is disposed in the light-transmitting area 202. Specifically, color filter layers 801 of different colors, such as a red filter layer, a blue filter layer, and a green filter layer, are disposed in the corresponding light-transmitting areas 202. When light emitted in the light emitting layer reaches the color filter layer 801, different colors are realized.
In the embodiment of the present invention, when the color filter layer 801 is disposed, the color filter layer can be prepared by a photolithography process or an inkjet printing process, and meanwhile, when the color filter layer is disposed, the thickness of the color filter layer 801 in different regions is ensured to be consistent with the thickness of the black matrix layer 200.
Furthermore, in the embodiment of the present invention, the black matrix layer 200 and the color filter layer 801 form a filter layer of the display panel, and the filter layer is disposed in the display panel, thereby eliminating the circular polarizer structure in the prior art. In addition, the filter layer provided by the embodiment of the invention is provided with the porous microstructure, so that a uniform rough surface is formed, when light enters the porous structure, the porous structure effectively enhances the absorption of the light, and the light forms diffuse reflection on the porous microstructure, so that the reflectivity of the black matrix layer is further reduced, and the display contrast is improved. Therefore, the filter layer provided by the embodiment of the invention has better effect on light and better display effect of the display panel.
Further, an embodiment of the present invention further provides a display panel, wherein a module of the display panel is provided with a structure of a filter layer provided in the embodiment of the present invention, so that a polarizer film layer is omitted, and the filter layer provided in the embodiment of the present invention is directly used as a substitute, thereby effectively increasing an effect of the display panel on light and contrast of a display image. Thereby effectively improving the display performance of the display panel.
