[0030] Hereinafter, the technical means in the embodiment of the present invention will be described clearly and completely with reference to the drawings in the embodiment of the present invention, but it is clear that the described embodiment is not all of the embodiments of the present invention, but only a part of the embodiment. Based on the embodiment of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention. In addition, it should be understood that the specific embodiment described herein is for explaining and interpreting the present invention, and is not for limiting the present invention. In the present invention, unless otherwise stated, the directional terms used, such as "upper" and "lower", usually mean the upper and lower in the state in which the device is actually used or in operation, specifically the drawing direction in the attached drawings, while "inner" and "outer" refer to the outline of the device.
[0031] The embodiments of the present invention provide a display panel and a tiling panel, which will be described in detail below. Note that the order of description of the embodiments below does not limit the preferred order of the embodiments.
[0032] In addition, if desired, the tiling panel includes at least two first panels and at least one second panel. The at least two first panels are arranged in a tiling manner, and a slit is provided between two adjacent first panels. The second panel is provided on the two adjacent first panels to shield the slit. The second panel includes a panel body and a lattice layer. The lattice layer is provided on the panel body. The front luminance of the panel body is greater than the front luminance of the first panel.
[0033] 1 to 3, a display panel 100 according to a first embodiment of the present invention includes a panel body 10 and a lattice layer 20. The lattice layer 20 is formed on the panel body 10. The lattice layer 20 includes a plurality of lattices 21. The plurality of lattices 21 are arranged at intervals along a first direction m. The plurality of lattices 21 are further arranged at intervals along a second direction n. The first direction m and the second direction n intersect with each other.
[0034] In the embodiment of the present invention, by forming the lattice layer 20 on the panel body 10, i.e., integrating the lattice layer 20 on the panel body 10, the effect of achieving a thin display panel 100 is achieved, and by arranging a plurality of lattices 21 at intervals along the first direction m and the second direction n, respectively, the side viewing brightness can be reduced.
[0035] If desired, the lattice layer 20 may be formed directly on the panel body 10 using a transfer method or a punching method.
[0036] Since the gratings 21 are spaced apart in both the first direction m and the second direction n, i.e., openings k are provided between adjacent gratings 21, a part of the side light can pass through the openings k, and a part of the side light is blocked by the gratings 21, reducing the side view luminance, but achieving a non-zero side view luminance. In other words, in the case of a wide viewing angle, the visibility of the side view is still there.
[0037] In addition, when the side view luminance at a certain viewing angle is below a threshold, the viewing angle is invisible to the user, that is, the user cannot see the display content of the panel at that viewing angle. Therefore, by reducing the side view luminance of the display panel 100, the effect of reducing the viewing angle can be achieved to a certain extent.
[0038] Optionally, the first direction m is perpendicular to the second direction n. In some embodiments, the first direction m is not perpendicular to the second direction n, for example, the angle between the first direction m and the second direction n may be 45 degrees, 60 degrees, or 120 degrees.
[0039] If desired, the panel body 10 may be an LED panel, such as a micro-LED panel, a sub-millimeter LED panel, a quantum dot LED panel, or an organic light-emitting diode panel, or an OLED panel, or may be a liquid crystal display panel.
[0040] Optionally, the panel body 10 includes a driving substrate 11, a light emitting element 12, a sealing layer 13, a color filter 14 and a planarization layer 15.
[0041] A light emitting element 12 is provided on a driving substrate 11. A sealing layer 13 covers the light emitting element 12. A color filter layer 14 is formed on the sealing layer 13. A planarization layer 15 is formed on the color filter layer 14. A lattice layer 20 is formed on the planarization layer 15.
[0042] Optionally, the light emitting element 12 emits white light, and may be, for example, a white LED light emitting element or a blue LED light emitting element combined with a light conversion film. The color filter layer 14 filters the light emitted from the light emitting element 12 to form red light, green light, and blue light. Optionally, the color filter layer 14 includes a red resist, a green resist, and a blue resist.
[0043] Optionally, the driving substrate 11 includes a substrate and a thin film transistor disposed on the substrate, where the thin film transistor may be a top gate type, a bottom gate type or a dual gate type.
[0044] In some embodiments, the panel body 10 can omit the color filter layer 14. That is, the light-emitting element 12 includes a light-emitting element that emits red light, a light-emitting element that emits green light, and a light-emitting element that emits blue light. Or, the light-emitting element 12 is a light-emitting element that emits monochromatic light, and a light conversion film can be formed on the light-emitting element to emit red, green, or blue light.
[0045] Optionally, the display panel 100 further includes a protective layer 30 covering the grating layer 20 .
[0046] Optionally, see Fig. 3, a plurality of gratings 21 extend along a first direction m. When the length of the gratings 21 in the first direction m is greater than the width in the second direction n and the gratings 21 are applied to a panel, more side light can be blocked in the first direction m, and the side view luminance in the first direction m is smaller than the side view luminance in the second direction n. Since the side view luminance in the first direction m and the second direction n are different, it is possible to facilitate attachment in different directions as required and improve the applicability of the grating layer.
[0047] Optionally, the opening width between two adjacent gratings 21 in a first direction m is defined as a first width. The opening width between two adjacent gratings 21 in a second direction n is defined as a second width. When the first width is smaller than the second width and applied to a panel, less side light is transmitted in the second direction n, further resulting in a greater side view luminance in the first direction m than in the second direction n.
[0048] If desired, the material of the grid 21 may be, for example, an inorganic metal material such as Cr (chromium), Mo (molybdenum), or Mn (manganese); CrO x , MoO x The material may be a black light-opaque material such as a metal oxide material such as MnO2, or a mixed material of a metal and a metal oxide, or a black organic resin material such as black polystyrene or black photoresist.
[0049] If desired, the shape of the grating 21 may be rectangular, trapezoidal or other shape.
[0050] Optionally, the width of the grating 21 is 8 μm or more, for example, 8 μm, 9 μm, or 10 μm. The length of the grating 21 is 35 μm to 75 μm, for example, 35 μm, 45 μm, 55 μm, 65 μm, or 75 μm. The thickness of the grating 21 is 50 μm to 130 μm, for example, 50 μm, 70 μm, 90 μm, 110 μm, or 130 μm.
[0051] If desired, in the lattice layer 20, a plurality of lattices 21 are arranged at equal intervals.
[0052] 4, in another planar structure of the first embodiment, the lattice layer 20 includes a first region q1 located in the middle region and a second region q2 provided on both sides of the first region q1. The arrangement density of the lattices 21 located in the first region q1 is smaller than the arrangement density of the lattices 21 located in the second region q2.
[0053] When the lattice layer 20 of this embodiment is applied to a tiling panel, lattices 21 of different arrangement densities are provided in different regions, so that the front luminance of the first region q1 is greater than the front luminance of the second region q2, thereby providing a smooth transition in the luminance of the entire tiling panel.
[0054] Optionally, in the second direction n, the pitch between the gratings 21 located in the first region q1 is greater than the pitch between the gratings 21 located in the second region q2.
[0055] If desired, the height of the grating 21 located in the first region q1 is smaller than the height of the grating 21 located in the second region q2. This makes the side view luminance located in the first region q1 greater than the side view luminance located in the second region q2. The height direction is perpendicular to the plane mn.
[0056] Optionally, the method for manufacturing the display panel 100 according to the embodiment of the present invention includes steps B1 to B2.
[0057] Step B1: providing a panel body 10.
[0058] Step B2: forming a lattice layer 20 on the panel body 10.
[0059] Step B2 includes steps B21 and B22.
[0060] Step B21: forming a lattice material layer on the panel body 10;
[0061] If desired, the material of the grating material layer may be, for example, an inorganic metal material such as Cr (chromium), Mo (molybdenum), or Mn (manganese); CrO x , MoO x The material may be a black light-opaque material such as a metal oxide material such as MnO2, or a mixed material of a metal and a metal oxide, or a black organic resin material such as black polystyrene or black photoresist.
[0062] Step B22: punching the lattice material layer to form a plurality of lattices 21;
[0063] Optionally, step B22 includes steps B221 to B223.
[0064] In step B221, a first punching die is used to punch out a layer of grating material to form a plurality of gratings 211.
[0065] In step B222, a second punch die is used to punch out the layer of grating material to form a plurality of gratings 212.
[0066] In step B223, the portions of the grating material layer other than the first grating 211 and the second grating 212 are removed.
[0067] The first punching die is provided with first punch holes patterned similarly to the multiple first lattice 211. The second punching die is provided with second punch holes patterned similarly to the multiple second lattice 212.
[0068] In some embodiments, a punching die can be used to punch out the lattice material layer to form a plurality of first lattices 211 and a plurality of second lattices 212. This achieves the effect of saving the punching die.
[0069] The manufacturing method of the display panel 100 according to the embodiment of the present invention includes the following steps: The method further includes step B3 of sequentially laminating a protective layer on the lattice layer 20.
[0070] This completes the manufacturing process of the display panel 100 according to the embodiment of the present invention.
[0071] In some embodiments, the grating layer 20 may be formed on the panel body 10 using a transfer method.
[0072] 5, based on the first embodiment of the present invention, the lattice layer 20 of the display panel 100 of the second embodiment further includes a connector ty. In the first direction m, the connector ty is connected between two adjacent lattices 21. The height of the connector ty is smaller than the height of the lattices 21.
[0073] By connecting low-height connectors ty between the gratings 21, the transfer method makes it easy to release the gratings 21. The connectors ty can also block part of the light at wide viewing angles, further reducing the luminance at wide viewing angles.
[0074] If desired, the connecting body ty is provided in the same layer as the lattice 21 and is integrally molded. The material of the connecting body ty is the same as the material of the lattice 21.
[0075] 6 and 7, based on the first embodiment, the grating 21 of the grating layer 20 in the display panel 100 of this third embodiment includes two types.

[0078] In the display panel 100 of the third embodiment, the first grating 211 and the second grating 212 are provided in combination, thereby further reducing the side view luminance in the first direction m.
[0079] If desired, the first lattice 211 is connected to the second lattice 212. That is, the first lattice 211 is cross-connected to the second lattice 212.
[0080] In the first direction m, a first opening k1 is disposed at a distance between two adjacent first gratings 211. In the second direction n, a second opening k2 is disposed at a distance between two adjacent second gratings 212.
[0081] At least some of the first openings k1 form a first light tunnel g1 along the second direction n. At least some of the second openings k2 form a second light tunnel g2 along the first direction m.
[0082] In the display panel 100 of this third embodiment, a first grating 211 and a second grating 212 are arranged adjacent to each other so as to intersect, thereby forming a plurality of first light tunnels g1 and a plurality of second light tunnels g2 so as to uniformize the side view luminance in the first direction m and the second direction n of the lattice layer 20.
[0083] 8, the difference between the display panel 100 of the fourth embodiment and the display panel 100 of the first embodiment is that the plurality of gratings 21 includes a plurality of first gratings 211 and a plurality of second gratings 212.

Also, the first grating 211 corresponds to the second opening k2, and the second grating 212 corresponds to the first opening k1, improving the uniformity of the light passing through the grating layer 20.

[0097] Optionally, the first opening k1 and the second opening k2 overlap to form a hollow region 1k. The hollow regions 1k are arranged along a third direction h to form a third light tunnel g3. The hollow regions 1k are arranged along a fourth direction j to form a fourth light tunnel g4.
[0098] If desired, the first opening k1 and the second opening k2 have the same size. The first direction m, the second direction n, the third direction h, and the fourth direction j intersect two by two.

[0103] Accordingly, referring to FIG. 11, an embodiment of the present invention further provides a tiling panel comprising at least two first panels p1 and at least one second panel p2.
[0104] At least two first panels p1 are arranged in a tiled manner, and a slit fx is provided between two adjacent first panels p1.
[0105] The second panels p2 are provided on the light exit surfaces of two adjacent first panels p1 and cover the slits fx.
[0106] The second panel p2 is the display panel 100 of any one of the above embodiments.
[0107] The side view luminance of the panel body 10 is greater than the side view luminance of the first panel p1.
[0108] The tiling direction of two adjacent first panels p1 is arranged to intersect with the first direction m. The first panels p1 are arranged to ensure a decrease in the side view luminance of the second panel p2, and it is guaranteed that the side view luminance of the second panel p2 is not 0 in the entire tiling panel 1000.
[0109] Optionally, the tiling direction of the first panel p1 is perpendicular to the first direction m, so that the extension direction of some of the light tunnels coincides with the tiling direction.
[0110] In the second panel p2 of the tiling panel 1000 of the embodiment of the present invention, a lattice layer 20 is formed on the panel body 10, thereby reducing the side view luminance and front view luminance of the second panel p2 and making the side view luminance and front view luminance of the entire tiling panel 1000 consistent with each other.
[0111] In addition, when the side view luminance at a certain viewing angle is below a threshold, the viewing angle is invisible to the user, that is, the user cannot see the display content of the panel at that viewing angle. Therefore, by reducing the side view luminance of the display panel 100, the effect of reducing the viewing angle can be achieved to a certain extent.
[0112] Since the viewing angle of the second panel p2 is larger than that of the first panel p1, the provision of the lattice layer 20 achieves the effect of matching the viewing angles of the first panel p1 and the second panel p2.
[0113] If desired, the first panel p1 may be, but is not limited to, a liquid crystal display panel. A prism sheet may be further provided on the light output side of the first panel p1. The panel body 10 includes a color filter 14 provided on the light emitting element 12.
[0114] By forming the color filter 14 on the second panel p2, the color gamuts of the first panel p1 and the second panel p2 are made to match.
[0115] See FIG. 12, in some embodiments, the second panel p2 may be disposed on the light-incident surfaces of two adjacent first panels p1.
[0116] The light incident surface and the light exit surface are disposed opposite each other, that is, the light exit surface is the front surface of the first panel p1, and the light incident surface is the rear surface of the first panel p1.
[0117] If desired, a second panel p2 is provided in the non-display area of the first panel p1. A portion of the second panel p2 that corresponds to the non-display area is transparent.
[0118] By providing the second panel p2 on the back surface of the first panel p1, a certain amount of light consumption is provided in a film layer in a non-display area of the first panel p1 so as to reduce the light output brightness of the first panel p2, thereby reducing the number of lattices 21 installed in the lattice layer 20 and reducing the difficulty of manufacturing the lattice layer.
[0119] The above provides a detailed description of the display panel and tiling panel according to the embodiments of the present invention. Although the present specification uses specific examples to explain the principles and embodiments of the present invention, the explanation of the above examples is merely for understanding the method of the present invention and its core ideas. Meanwhile, a person skilled in the art may make changes to the specific embodiments and scope of application based on the concept of the present invention. In summary, the contents of this specification should not be construed as limiting the present invention.
