Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an embodiment of a display panel of the present application, and fig. 2 is a schematic structural diagram of an embodiment of an orthogonal projection of a second via and a light emitting unit on a substrate in fig. 1. The display panel 10 provided by the present application may be an OLED display panel, a Micro-OLED display panel, or the like. The display panel 10 may include a substrate 100, a pixel defining layer 102, and a light shielding layer 104.
Specifically, the substrate 100 may be a flexible substrate made of polyimide or the like; of course, the substrate 100 may be a hard substrate, and a material thereof may be glass or the like.
The pixel defining layer 102 is disposed on one side of the substrate 100 and includes a plurality of openings (not labeled), each of which has a light emitting unit 101 disposed therein. The light emitting unit 101 may be a red light emitting unit R, a blue light emitting unit B, a green light emitting unit G, or the like.
The light-shielding layer 104 is located on a side of the pixel defining layer 102 away from the substrate 100, and the light-shielding layer 104 may be made of a black insulating material. The light shielding layer 104 is provided with a plurality of first via holes 1040 and a plurality of second via holes 1042; wherein, the orthographic projection of the first via 1040 on the substrate 100 covers the orthographic projection of the light emitting unit 101 at the corresponding position on the substrate 100. For example, the first via hole 1040 is disposed at a position of the light shielding layer 104 corresponding to each light emitting unit 101, so that the light shielding layer 104 does not block the light emitted by the light emitting unit 101. The orthogonal projection of the second via 1042 on the substrate 100 is located within the orthogonal projection of the pixel defining layer 102 on the substrate 100. For example, a plurality of second via holes 1042 may be disposed at positions of the light shielding layer 104 corresponding to optical modules (e.g., an underscreen fingerprint identification module, an underscreen camera module, etc.), and positions of the second via holes 1042 correspond to positions of the pixel definition layer 102, so as to improve light intensity reaching the optical modules; the optical module may be located on a side of the pixel defining layer 102 away from the light shielding layer 104; when the optical module is an underscreen fingerprint identification module, it may be disposed in the same layer as an array layer (not labeled) located between the pixel defining layer 102 and the substrate 100 in the display panel 10; of course, it may also be located on the side of the substrate 100 facing away from the pixel defining layer 102 (i.e., on the outer side of the display panel 10); when the optical module is an under-screen camera module, it may also be located on the side of the substrate 100 facing away from the pixel defining layer 102. The structure of the orthographic projection of at least a part of the second via 1042 on the substrate 100 is different from the structure of the orthographic projection of the adjacent light emitting unit 101 on the substrate 100 (as shown in fig. 2). The above-mentioned structural differences include different shapes, or the same shape but different angles. For example, the orthogonal projection of the second via 1042 on the substrate 100 is circular in shape, and the orthogonal projection of the adjacent light emitting unit 101 on the substrate 100 is rectangular. For another example, the shape of the orthographic projection of the second via 1042 on the substrate 100 is a trapezoid with respect to the orthographic projection of the adjacent light emitting unit 101 on the substrate 100, but one may be considered as an orthotrapezoid and the other may be considered as an inverted trapezoid.
The color block blocks 106 are disposed corresponding to the first vias 1040. The color-resisting block 106 can be located inside the first via hole 1040 at the corresponding position, and the color-resisting block 106 only allows the light with the same color as the light emitted by the light-emitting unit 101 at the corresponding position to pass through. Namely, the color block 106 at the position of the red light-emitting unit R is a red color block which allows only red light to pass through; the color block 106 at the position of the blue light emitting unit B is a blue color block which allows only blue light to pass therethrough; the color block 106 at the position of the green light emitting unit G is a green color block which allows only green light to pass through. In addition, in order to improve the purity of light and ensure the display effect, the orthographic projection of the color resist block 106 on the substrate 100 may coincide with the orthographic projection of the light emitting unit 101 at the corresponding position on the substrate 100.
The external light is usually natural light, the color-resisting blocks 106 at various positions usually allow only one color of the natural light to pass through, and most of the light in the natural light is blocked by the color-resisting blocks 106, so most of the light irradiated to the color-resisting blocks 106 cannot enter the display panel 10; after the external light irradiates the light-shielding layer 104, the light-shielding layer 104 can absorb the external light, and the external light irradiating the light-shielding layer 104 cannot enter the display panel 10. After the external light does not enter the display panel 10, the external light cannot be reflected inside the display panel 10, and therefore, the light shielding layer 104 and the color resistance block 106 are used to replace a circular polarizer, so that the reflectivity of the display panel 10 can be reduced, and since the thicknesses of the light shielding layer 104 and the color resistance block 106 are far smaller than that of the circular polarizer, and the transmittance of the color resistance block 106 is greater than that of the circular polarizer, the thickness and the power consumption of the display panel 10 can be effectively reduced. In addition, in order to improve the light transmittance of the optical module region, the second via hole 1042 is disposed on the light-shielding layer 104 at a position corresponding to the optical module, and the orthogonal projection structure of at least a portion of the second via hole 1042 on the substrate 100 is different from the orthogonal projection structure of the adjacent light-emitting unit 101 on the substrate 100. The structural design of the second via-hole 1042 and the light emitting unit 101 can destroy the spatial frequency of light, and eliminate the condition of generating a part of moire fringes, thereby reducing the probability of generating moire fringes and improving the display effect.
In one embodiment, referring to fig. 2, the orthographic projection of the second vias 1042 on the substrate 100 and the orthographic projection of the adjacent light-emitting units 101 on the substrate 100 form a repeating unit 20, the repeating unit 20 includes at least two groups of the same light-emitting units 101, the number of the light-emitting units 101 in each group of the light-emitting units 101 is at least two, and the light-emitting colors are at least two. Each group of the light emitting cells 101 described above may be referred to as a pixel, and for example, as shown in fig. 2, each group of the light emitting cells 101 may include adjacent red light emitting cells R, green light emitting cells G, and blue light emitting cells B. The repeating unit 20 in fig. 2 includes four sets of the same light emitting unit 101. The design method can make the area of the repeating unit 20 formed by the second via 1042 on the light shielding layer 104 (not shown in fig. 2) and the light emitting unit 101 in the pixel defining layer 102 (not shown in fig. 2) larger, so as to further reduce moire.
Alternatively, in the repeating unit 20, the structure of the orthographic projection of the plurality of second vias 1042 on the substrate 100 includes at least two kinds. The shape of the orthographic projection of the second via 1042 on the substrate 100 includes a circle or a square or a long stripe or an ellipse or a diamond or a trapezoid or an irregular shape. The irregular shape may be an unconventional, unusual shape, such as some irregular curved shapes, broken lines, etc. Different structures are realized by different shapes or the same shape and different angles. For example, as shown in fig. 2, the orthogonal projection structure of the second vias 1042 on the substrate 100 includes two types, which are trapezoids with different angles, one of which may be a regular trapezoid, and the other may be an inverted trapezoid. For another example, as shown in fig. 3, fig. 3 is a schematic structural diagram of another embodiment of an orthographic projection of the second via hole and the light emitting unit on the substrate in fig. 1. In the repeating unit 20a, the structure of the orthographic projection of the plurality of second vias 1042a on the substrate 100a includes three kinds, which are a regular trapezoid, an inverted trapezoid and a circle. At this time, the orthographic projection structure of the plurality of light emitting units 101 in the repeating unit 20 on the substrate 100 may be one, for example, all of which are rectangular, etc., so as to reduce the difficulty of the manufacturing process. In the above design, the light-shielding layer 104 forms at least two second via holes 1042 with different structures by irregularly digging holes, so as to increase the area of the repeating unit 20, and the process is relatively simple.
Further, as shown in fig. 2, in the repeating unit 20, the plurality of light emitting units 101 are arranged in a plurality of rows in the first direction X and the second direction Y, respectively, which may be perpendicular to each other. At least one second via 1042 is correspondingly disposed between two adjacent light emitting units 101 in at least one of the first direction X and the second direction Y. For example, in the first direction X in fig. 2, at least one second via 1042 is correspondingly disposed between two adjacent light emitting units 101; of course, in other embodiments, at least one second via 1042 may be correspondingly disposed between two adjacent light emitting units 101 in the second direction Y. Alternatively, at least one second via 1042 may be disposed between two adjacent light emitting units 101 in the first direction X or the second direction Y. The above-mentioned repeating unit 20 has a simple structural design and a process is easy to implement.
Further, in at least one of the first direction X and the second direction Y, one second via 1042 is correspondingly disposed between two adjacent light emitting units 101, and the second vias 1042 of at least two structures are alternately arranged. This design can increase the area of the repeating unit 20 as much as possible to reduce moire. When the second via holes 1042 in the repeating unit 20 include two structures, which are respectively denoted by A, B, the second via holes 1042 in the repeating unit 20 may be alternately arranged in at least one direction in the manner of ABAB …. When the structures of the second via holes 1042 in the repeating unit 20 include three structures, which are respectively denoted by A, B, C, the second via holes 1042 in the repeating unit 20 may be alternately arranged in an abcabcabc … manner in at least one direction; alternatively, as shown in fig. 3, the second vias 1042a in the repeating unit 20a may also be alternately arranged in at least one direction in the manner of abaacabac …. The specific alternate arrangement rule can be set according to actual requirements. It is expected that as the kinds of the structures of the second via holes 1042 in the repeating unit 20 are more varied, the alternating arrangement is more complicated, and the moire is less obvious as the area of the repeating unit 20 is larger.
Of course, the structural design of the second via 1042 may be other in other ways. For example, as shown in fig. 4, fig. 4 is a schematic structural diagram of another embodiment of an orthographic projection of the second via hole and the light emitting unit in fig. 1 on the substrate. In the repeating unit 20b, the plurality of light emitting units 101b are arranged in a plurality of rows in the first direction X and the second direction Y, respectively; in one of the first direction X and the second direction Y, a second via 1042b is disposed between two adjacent rows of light emitting units 101b, and the second via 1042b at least spans the two rows of light emitting units 101b; the second vias 1042b of at least two structures are alternately arranged in the other one of the first direction X and the second direction Y. The orthographic projection of the second via hole 1042b on the substrate 100b may have at least one of a long stripe shape, a zigzag shape and a wave shape. Taking fig. 4 as an example, in the repeating unit 20b, in the second direction Y, one second via 1042b is disposed between two adjacent rows of the light emitting units 101b, and the second via 1042b can span three rows of the light emitting units 101b; in the first direction X, the second vias 1042b of two structures are alternately arranged. In the above design, since the second via holes 1042b span across the rows of light emitting units 101b, the area of the repeating unit 20b can be further increased to further weaken the moire pattern.
Generally speaking, in order to achieve a full screen effect, the optical module may include an off-screen camera module and an off-screen fingerprint identification module, the light shielding layer 104 includes a first region (not labeled) corresponding to the off-screen camera module and a second region (not labeled) corresponding to the off-screen fingerprint identification module, and the first region and the second region are respectively and correspondingly provided with a plurality of second via holes 1042; the plurality of second via holes 1042 corresponding to the first region have a first minimum orthographic projection among a plurality of orthographic projections formed on the substrate 100, respectively, the plurality of second via holes 1042 corresponding to the second region have a second minimum orthographic projection among a plurality of orthographic projections formed on the substrate 100, respectively, and an area of the first minimum orthographic projection is larger than an area of the second minimum orthographic projection. This design can make the luminousness of the module position department of making a video recording under the screen higher for the function of the module of making a video recording under the screen can be guaranteed. Certainly, in other embodiments, when the camera module does not adopt the under-screen structure design, the film layer of the whole display panel 10 at the position of the camera module is hollowed; at this time, the second via 1042 may be formed only on the light shielding layer 104 at the position of the underscreen fingerprint identification module. Of course, in other embodiments, the second via 1042 may be formed in the region of the light-shielding layer 104 corresponding to the non-optical module.
In addition, in the above embodiments, different structures of the second via 1042 of the light shielding layer 104 are described. Of course, in other embodiments, the orthographic projection structure of all the second via holes 1042 on the substrate 100 on the light shielding layer 104 may also be one, and the orthographic projection structure of the light emitting unit 101 on the substrate 100 may include multiple structures, which may also achieve the purpose of reducing moire fringes.
In addition, in order to block the water vapor and improve the uniformity of the surface of the display panel 10, referring to fig. 1 again, the display panel 10 may further include a planarization layer 108 covering the light-shielding layer 104 and the side of the plurality of color-blocking blocks 106 away from the substrate 100, and filling the second via holes 1042.
In addition, referring to fig. 1 again, the display panel 10 provided in the present application may further include a packaging layer 103 and a touch layer 105; the packaging layer 103 is located on one side of the pixel definition layer 102, which is far away from the substrate 100, and the touch layer 105 is located on one side of the packaging layer 103, which is far away from the substrate 100; the light-shielding layer 104 is located on a side of the touch layer 105 away from the substrate 100.
Referring to fig. 5, fig. 5 is a schematic structural diagram of an embodiment of a display device of the present application, where the display device 30 includes the display panel 300 and the optical module mentioned in any of the above embodiments; the optical module may be located inside the display panel 300 or at one side of the display panel 300. For example, when the optical module is an underscreen fingerprint identification module, it may be disposed on the same layer as the array layer located between the pixel defining layer and the substrate in the display panel 300; of course, it may also be located on the side of the substrate facing away from the pixel defining layer (i.e., on the outside of the display panel 300); when the optical module is an under-screen camera module, it may be located on a side of the substrate away from the pixel defining layer (i.e., on an outer side of the display panel 300).
