In particular, the display panel can be used for manufacturing devices having a display function such as mobile phones, computers, televisions, and the like. The display panel may include a substrate, a light emitting function layer 100, and a color resistance layer 200 disposed from bottom to top. It is understood that the orientation is from bottom to top in fig. 1, and other material layers may be directly contacted between the substrate and the light-emitting function layer 100, and between the light-emitting function layer 100 and the color resistance layer 200, and are not limited in this respect.

Each pixel unit 110 may emit light of one color (e.g., one of red, blue, green, or white light), and the plurality of pixel units 110 may include a plurality of pixel units 110 emitting light of different colors, e.g., it may include a plurality of red pixel units emitting red light, a plurality of blue pixel units emitting blue light, and a plurality of green pixel units emitting green light; of course, the plurality of pixel units 110 are not limited to being configured by the pixel units 110 emitting three colors of red, green and blue, but may be configured by a plurality of pixel units 110 emitting other colors.
The color resist layer 200 is disposed over the light emitting function layer 100, the color resist layer 200 may include a first black matrix 210 and a plurality of color resists 220, and the first black matrix 210 and the color resists 220 may be disposed in the same layer.
The first black matrix 210 may be composed of a black material or a light absorbing material of other colors so that the first black matrix 210 may absorb most of light irradiated thereto. The first black matrix 210 may have a plurality of first openings, and the number of the first openings may be the same as the number of the color resistors 220, so that one color resistor 220 may be disposed in one first opening.
The number of the color resistors 220 may be the same as the number of the pixel units 110, each color resistor 220 may be correspondingly disposed above one pixel unit 110, taking one color resistor 220 and the corresponding pixel unit 110 as an example, the orthographic projection of the color resistor 220 on the substrate covers the orthographic projection of the pixel unit 110 on the substrate, and the area of the orthographic projection of the color resistor 220 on the substrate is equal to the area of the orthographic projection of the pixel unit 110 on the substrate, that is, the orthographic projections of the two are coincident.
In addition, the color of the light allowed to pass through each color resistor 220 is the same as the color of the light emitted by the pixel unit 110 corresponding to the color resistor 220. The light emitting function layer 100 includes: red, green, and blue pixel cells (R, G, B in the figure, respectively) are taken as examples; the plurality of color resistors 220 may also include a red color resistor allowing only red light to pass through, a blue color resistor allowing only blue light to pass through, and a green color resistor allowing only green light to pass through; the red color resistor is correspondingly positioned above the red light pixel unit, the green color resistor is correspondingly arranged above the green light pixel unit, and the blue color resistor is correspondingly arranged above the blue light pixel unit, so that the red light emitted by the red light pixel unit can be emitted through the corresponding red color resistor; green light emitted by the green light pixel unit can be emitted through the corresponding green color resistor; the blue light emitted by the blue pixel units can be emitted through the corresponding blue color resistors, that is, the light of different colors emitted by the plurality of pixel units 110 can be emitted through the corresponding color resistors 220.
Meanwhile, an upper surface of the first black matrix 210 facing away from the substrate may be provided with a concave-convex portion. It can be understood that although the first black matrix 210 can absorb most of the light, about 5% of the light is reflected by the surface of the first black matrix 210. The concave-convex portion may be an uneven structure for increasing the surface roughness of the first black matrix 210, and may make the external ambient light reflected by the first black matrix 210 irregularly reflect toward different directions, thereby forming a diffuse reflection phenomenon, further reducing the intensity of the external ambient light reflected by the display panel, improving the display effect of the display panel, and reducing the reflectivity of the external ambient light.
The structure of the concave-convex portion may be various, for example, the concave-convex portion may include a plurality of protrusions arranged in an array. A plurality of protrusions may be formed on the upper surface of the first black matrix 210, so that the first black matrix 210 forms an uneven surface.
When the external ambient light is incident to the display panel, the external ambient light irradiated on the first black matrix 210 may be absorbed, and a portion of the external ambient light irradiated on the color resistor 220 may be filtered, for example, the external ambient light passes through the red color resistor, only the red light may pass through, and other colors, such as blue and green light, may be filtered. Therefore, the light intensity of the external ambient light is weakened after passing through the color resist layer 200, and after the external ambient light is reflected by some metal layers in the light emitting functional layer 100, the reflected external ambient light passes through the color resist layer 200 again, and the light intensity is further reduced, so that the purpose of reducing the reflection of the external ambient light is achieved, the reflectivity of the display panel is reduced, and the display effect of the display panel is improved. In addition, the color resist layer 200 is thinner and more flexible than the circular polarizer in the prior art, which can further improve the flexibility of the display panel and reduce the thickness thereof.

As a preferred embodiment of the concave-convex portion, referring to fig. 2, the concave-convex portion includes a plurality of first scribe grooves 211 (only indicated by lines in the drawing because the width of the first scribe grooves 211 is small) which are arranged in parallel and at equal intervals.
Specifically, the first scribing groove 211 may extend in the lateral direction of fig. 2, and the first scribing groove 211 may form a scribing groove recessed downward by making a scratch on the surface of the first black matrix 210, so that the processing is convenient, and the roughness of the surface of the first black matrix 210 can be improved. The plurality of first grooves 211 are arranged in parallel and at intervals, so that a coverage area of the concave-convex portion is increased, roughness of the surface of the first black matrix 210 is further increased, a diffuse reflection capability of the first black matrix is improved, and intensity of reflected external environment light is reduced.
With reference to fig. 2, in addition to the first scribing groove 211, the concave-convex portion further includes a plurality of second scribing grooves 212 that are parallel to each other and are disposed at equal intervals, and a preset angle is formed between an extending direction of the second scribing grooves 212 and an extending direction of the first scribing groove 211, the preset angle may be within 30 degrees to 150 degrees, the second scribing grooves 212 may form a downward-concave scribing groove by making a scratch on the surface of the first black matrix 210, the processing is convenient, the plurality of second scribing grooves 212 may further increase a coverage area of the concave-convex portion and a roughness of the surface of the first black matrix 210, improve a diffuse reflection capability, and reduce an intensity of the reflected external ambient light.
In this embodiment, the positional relationship between the plurality of first grooves 211 and the plurality of second grooves 212 is not limited, for example, the first black matrix 210 may be divided into two mutually non-intersecting regions, one region is provided with the first grooves 211, and the other region is provided with the second grooves 212.
In another preferred embodiment, each of the second scribing grooves 212 intersects at least one of the first scribing grooves 211, so that the first scribing grooves 211 and the second scribing grooves 212 are alternately formed on the first black matrix 210, further improving the diffuse reflection capability of the first black matrix 210.
It will be appreciated that, in addition to providing the first scribing groove 211 and the second scribing groove 212, the concavo-convex part may be provided with at least one set of other scribing grooves extending in other directions, or the concavo-convex part may be provided with both scribing grooves and projections.
On the basis of the above embodiments, the display panel may further include an encapsulation layer 300, and the encapsulation layer 300 may be disposed outside the color resistance layer 200.
Preferably, an encapsulation layer 300 is disposed between the light emitting function layer 100 and the color resistance layer 200. The encapsulation layer 300 may be an organic film layer, an inorganic film layer, or an organic film layer and an inorganic film layer alternately, and the encapsulation layer 300 may cover the light emitting functional layer, thereby isolating water and oxygen and increasing the life of the light emitting functional layer 100.
Fig. 3 is a cross-sectional view of a display panel according to a second embodiment of the invention. Referring to fig. 3, the light-emitting functional layer 100 further includes a first electrode layer 120, a pixel defining layer 140, and a second electrode layer 130 sequentially stacked on the substrate; the pixel defining layer 140 is formed with a plurality of second openings, each of which has one pixel unit 110 disposed therein; a second black matrix 400 is further disposed between the second electrode layer 130 and the encapsulation layer 300; the orthographic projection of the first black matrix 210 on the substrate covers the orthographic projection of the second black matrix 400 on the substrate.
Specifically, the first electrode layer 120 and the second electrode layer 130 may be respectively connected to two sides of the pixel unit 110, and any two adjacent pixel units 110 are isolated by the pixel defining layer 140, so that when the first electrode layer 120 and the second electrode layer 130 are connected to a power supply, the light emitting material in the pixel unit 110 can emit light. Preferably, the first electrode layer 120 may include a plurality of first electrodes arranged in an array on the substrate; each of the first electrodes may be electrically connected to one pixel unit 110, and the second electrode layer 130 may be an entire layer structure covering the pixel defining layer 140 and the top surface of the pixel unit 110. Further, the first electrode layer 120 may be an anode layer, which may be made of ITO, and the second electrode layer 130 may be a cathode layer, which may be made of a metal material, and thus, the processing is convenient.
A second black matrix 400 is further disposed between the second electrode layer 130 and the encapsulation layer 300; the orthographic projection of the first black matrix 210 on the substrate covers the orthographic projection of the second black matrix 400 on the substrate. That is, the area of the projection of the first black matrix 210 on the substrate is greater than or equal to the area of the projection of the second black matrix 400 on the substrate, and the orthographic projection of the second black matrix 400 is located within the orthographic projection of the first black matrix 210, so that the light emitted by the pixel unit 110 is not affected.
The second black matrix 400 may also be made of a black material or a light absorbing material of another color, which can absorb a portion of the external ambient light reflected by the second electrode layer 130. Due to the filtering effect of the color resistor 220, the ambient light passing through the red color resistor cannot be emitted from the adjacent green color resistor and blue color resistor after being reflected by the second electrode layer 130, but can be emitted from the adjacent red color resistor, and the second black matrix 400 can absorb the reflected light to avoid being emitted from the adjacent same color resistor 220, thereby reducing the reflectivity of the display panel.
Preferably, the orthographic projection of the second black matrix 400 on the substrate coincides with the orthographic projection of the first black matrix 200 on the substrate, that is, the orthographic projection of the first black matrix 210 on the substrate coincides with the orthographic projection of the second black matrix 400 on the substrate, so that the amount of reflected light absorbed by the second black matrix 400 is increased as much as possible without affecting the light emission of the pixel unit 110, and the reflectivity is further reduced.
The embodiment also provides a display device, which comprises a display panel and a touch device arranged on the light-emitting side of the display panel.
Specifically, the display device may be a display device such as a mobile phone and a tablet computer, the touch control device may be a module capable of realizing touch control commonly used in the prior art, and the structure and the function of the display panel are the same as those of the above embodiment, which is specifically referred to the above embodiment, and is not limited specifically herein.
When the external ambient light is incident to the display panel, the external ambient light irradiated on the first black matrix 210 may be absorbed, and a portion of the external ambient light irradiated on the color resistor 220 may be filtered, for example, the external ambient light passes through the red color resistor, only the red light may pass through, and other colors, such as blue and green light, may be filtered. Therefore, the light intensity of the external ambient light is weakened after passing through the color resist layer 200, and after the external ambient light is reflected by some metal layers in the light emitting functional layer 100, the reflected external ambient light passes through the color resist layer 200 again, and the light intensity is further reduced, so that the purpose of reducing the reflection of the external ambient light is achieved, the reflectivity of the display panel is reduced, and the display effect of the display panel is improved. In addition, the color resist layer 200 is thinner and more flexible than the circular polarizer in the prior art, which can further improve the flexibility of the display panel and reduce the thickness thereof. The concave-convex portion may be an uneven structure for increasing the surface roughness of the first black matrix 210, and may make the external ambient light reflected by the first black matrix 210 irregularly reflect toward different directions, thereby forming a diffuse reflection phenomenon, further reducing the intensity of the external ambient light reflected by the display panel, improving the display effect of the display panel, and reducing the reflectivity of the external ambient light.
