[0002] With the development of flat panel display technology, the stability requirements for display panels have gradually increased. In recent years, organic light emitting diode (OLED) display panels have developed rapidly around the world, and organic light emitting diode display technology has also been increasingly advanced.

[0003] At present, in order to reduce the reflectivity of the organic light-emitting diode display panel under strong light, a polarizer is set on the light-emitting side of the organic light-emitting diode display panel. This anti-reflection method will reduce the light output rate and affect the life of the organic light-emitting diode display panel. In order to improve the light output rate of the organic light-emitting diode display panel, a non-polarizer technology can be used, that is, a color filter layer and a shading pattern are prepared on the cover plate of the organic light-emitting diode to replace the polarizer. Due to the insufficient assembly accuracy of the cover plate, the relative position relationship between the shading pattern on the cover plate and the light-emitting device on the array substrate is offset, and the shading area of ​​the shading pattern is increased, resulting in asymmetric left and right viewing angles of the display panel, affecting the display effect of the display panel.

[0004] Therefore, it is necessary to provide a display panel to improve this defect. Summary of the invention

[0045] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0046] An embodiment of the present application provides a display panel, which includes an array substrate, a light-emitting device layer, a packaging layer, a shading pattern and an opposing substrate, wherein the light-emitting device layer is arranged on one side of the array substrate, the packaging layer is arranged on a side of the light-emitting device layer away from the array substrate, the shading pattern is arranged in the packaging layer or on a side of the packaging layer away from the light-emitting device layer, the opposing substrate is arranged on a side of the shading pattern away from the light-emitting device layer, and the opposing substrate includes a continuously arranged filter portion.

[0047] In an embodiment of the present application, a shading pattern is produced on a side of the packaging layer away from the light-emitting device layer, and the filtering portion is produced only on the opposing substrate. This can avoid the deviation in the assembly accuracy of the opposing substrate from causing the area blocked by the shading pattern to shift, thereby improving the viewing angle of the display panel.

[0048] See also Figure 1 , Figure 1 A structural schematic diagram of the first display panel provided for an embodiment of the present application, the display panel 100 includes an array substrate 1, a light emitting device layer 2, a shading pattern 3 and an opposing substrate 4, the light emitting device layer 2 is arranged on one side of the array substrate 1, the light emitting device layer 2 has a plurality of light emitting devices, the shading pattern 3 is arranged on the side of the light emitting device layer 2 away from the array substrate 1, the opposing substrate 4 is arranged on the side of the shading pattern 3 away from the light emitting device layer 2, the opposing substrate 4 includes a continuously arranged filter portion 410, a plurality of filter portions 410 are continuously arranged to form a color filter layer 41, and no black matrix is ​​arranged in the color filter layer 41.

[0049] In the embodiment of the present application, the shading pattern 3 can also be called a black matrix. The shading pattern 3 and the color filter layer 41 are respectively made on different film layers. The shading pattern 3 is made on the side of the light-emitting device layer 2 away from the array substrate 1, and the color filter layer 41 is made on the opposite substrate 4. Since the shading pattern 3 is made on the side of the light-emitting device layer 2 away from the array substrate 1, when the shading pattern 3 is made, the area blocked by the shading pattern 3 is fixed and will not change. Even if there is a deviation in the alignment accuracy of the opposite substrate 4 and the array substrate 1, the offset of the opposite substrate 4 will not affect the area blocked by the shading pattern 3. The deviation of the area blocked by the shading pattern 3 is related to the process technology for forming the shading pattern 3. Since the process technology accuracy for forming the shading pattern 3 is higher than the alignment accuracy of the opposite substrate 4, the embodiment of the present application can reduce the shading of the light-emitting device by the shading pattern 3, thereby improving the viewing angle of the display panel.

[0050] In some embodiments, the array substrate 1 includes a substrate and a driving circuit layer (not shown in the figure), and the driving circuit layer is arranged on the substrate.

[0051] In some embodiments, the substrate may be a single-layer structure formed by an organic material or an inorganic material, or a multi-layer structure formed by stacking an organic material and an inorganic material. The organic material may be polyimide, and the inorganic material may be selected from at least one of glass, silicon nitride, silicon oxide, and silicon oxynitride.

[0052] In some embodiments, the driving circuit layer can be a multilayer structure composed of a semiconductor layer, a conductive layer, an inorganic insulating layer and an organic insulating layer. The driving circuit layer can be replaced by the film layer structure of the driving circuit layer in the existing display panel, which will not be elaborated here.

[0053] In some embodiments, see Figure 1 The light-emitting device layer 2 includes a stacked anode layer, a pixel definition layer 21, a hole injection layer 22, a hole transport layer 23, a light-emitting layer 24, an electron transport layer 25 and a cathode layer 26. The anode layer, the hole injection layer 22, the hole transport layer 23, the light-emitting layer 24, the electron transport layer 25 and the cathode layer 26 constitute a light-emitting device. The pixel definition layer 21 defines the shape of the light-emitting device. Multiple light-emitting devices can share the hole injection layer 22, the hole transport layer 23, the electron transport layer 25 and the cathode layer 26.

[0054] In some embodiments, see Figure 1The display panel further includes an encapsulation layer 5, which is disposed on a side of the light-emitting device layer 2 away from the array substrate 1, and a shading pattern 3 is disposed on a side of the encapsulation layer 5 away from the light-emitting device layer 2. By disposing the shading pattern 3 on the surface of the encapsulation layer 5 away from the light-emitting device layer 2, and manufacturing the color filter layer 41 on the opposite substrate 4, the assembly accuracy of the display panel can be controlled while ensuring the reflectivity of the display panel, and the process accuracy requirement for the bonding section of the opposite substrate is relatively low, which can avoid the situation where the shading area of ​​the shading pattern is increased due to the low assembly accuracy of the opposite substrate, thereby improving the symmetry and viewing angle of the display panel, thereby improving the display effect of the display panel, and further improving the yield rate of the display panel.

[0055] In some embodiments, see Figure 1 The encapsulation layer 5 is a thin film encapsulation structure, and the encapsulation layer 5 can be a laminated structure formed by stacking multiple inorganic encapsulation layers and at least one organic encapsulation layer.

[0056] In some embodiments, see Figure 1 The encapsulation layer 5 includes a first inorganic encapsulation layer 51, a first organic encapsulation layer 52 and a second inorganic encapsulation layer 53. The first inorganic encapsulation layer 51 is arranged on the side of the light-emitting device layer 2 away from the array substrate 1, the first organic encapsulation layer 52 is arranged on the surface of the first inorganic encapsulation layer 51 away from the light-emitting device layer 2, and the second inorganic encapsulation layer 53 is arranged on the surface of the first organic encapsulation layer 52 away from the first inorganic encapsulation layer 51.

[0057] In some embodiments, the material of the first inorganic encapsulation layer 51 is selected from silicon nitride, silicon oxynitride, silicon oxide, silicon carbide nitride, zinc oxide, or a combination of any one or more of aluminum oxide, and the material of the second inorganic encapsulation layer 53 is selected from silicon nitride, silicon oxynitride, silicon oxide, silicon carbide nitride, zinc oxide, or a combination of any one or more of aluminum oxide. The first inorganic encapsulation layer 51 and the second inorganic encapsulation layer 53 can be made of the same material or different materials, which is not limited here. The first inorganic encapsulation layer 51 and the second inorganic encapsulation layer 53 can be formed by chemical vapor deposition.

[0058] In some embodiments, the material of the first organic encapsulation layer 52 can be selected from any one or more combinations of acrylic acid, epoxy resin, polyimide, or silicone, and the first organic encapsulation layer 52 can be formed by coating or inkjet printing.

[0059] In some embodiments, see Figure 1, the shading pattern 3 is arranged on the surface of the second inorganic encapsulation layer 53 away from the first organic encapsulation layer 52. The material of the shading pattern 3 is black organic photoresist. The process of using the photolithography process to prepare the shading pattern 3 on the second inorganic encapsulation layer 53 is mature, and will not cause damage to the film structure of the second inorganic encapsulation layer 53, so that the viewing angle symmetry and the size of the viewing angle of the display panel can be improved without changing the film structure of the encapsulation layer 5 and ensuring that the encapsulation effect of the encapsulation layer 5 is not affected. In addition, the shading pattern 3 is arranged on the surface of the second inorganic encapsulation layer 53 away from the first organic encapsulation layer 52, and the distance between the shading pattern 3 and the pixel definition layer 21 and the light-emitting layer 24 in the thickness direction of the display panel can also be reduced, so that the shading area of ​​the light-emitting layer 24 by the shading pattern 3 can be further reduced, so that the viewing angle symmetry and the viewing angle of the display panel can be further improved.

[0060] In some embodiments, see Figure 2 , Figure 2 The embodiment of the present application provides a top view of the array substrate in the display panel, wherein the shading pattern 3 includes a plurality of shading portions 31 arranged vertically and horizontally and a plurality of first openings 32 formed by the shading portions 31, and each first opening 32 is aligned with a corresponding light-emitting layer 24 in the light-emitting device layer 2, and the first opening 32 can transmit part of the light emitted by the corresponding light-emitting layer 24.

[0061] In some embodiments, see Figure 2 The light-emitting layer 24 includes a red light-emitting layer 241, a green light-emitting layer 242 and a blue light-emitting layer 243. A plurality of red light-emitting layers 241 are arranged in a column along the second direction Y, a plurality of green light-emitting layers 242 are arranged in a column along the second direction Y, a plurality of blue light-emitting layers 243 are arranged in a column along the second direction Y, and the red light-emitting layers 241, the green light-emitting layers 242 and the blue light-emitting layers 243 are alternately arranged along the first direction X.

[0062] In some embodiments, see Figure 1 and Figure 3 , Figure 3 A schematic diagram of a light shielding pattern and a pixel definition layer in a display panel provided in an embodiment of the present application, wherein the pixel definition layer 21 includes a plurality of pixel definition portions 211 arranged in a vertical and horizontal manner and a plurality of pixel openings 212 formed by enclosing the pixel definition portions 211, and each light emitting layer 24 is disposed in a corresponding pixel opening 212, and the pixel opening 212 is used to define the shape of the light emitting layer 24 in a top view. Each first opening 32 is disposed in alignment with a corresponding pixel opening 212.

[0063] In some embodiments, see Figure 1The pixel definition portion 211 includes a first sub-portion 2111 and a second sub-portion 2112 , and the second sub-portion 2112 is disposed on the first sub-portion 2111 .

[0064] In some embodiments, see Figure 3 , the orthographic projection of the light shielding portion 31 on the pixel definition layer 21 is located inside the pixel definition portion 211. It should be noted that if the orthographic projection of the light shielding portion 31 is located outside the pixel definition portion 211, the light shielding portion 31 will block the light emitting layer 24 in the pixel opening 212 in the thickness direction of the display panel, resulting in asymmetric left-right viewing angles of the display panel. By making the orthographic projection of the light shielding portion 31 on the pixel definition layer 21 located inside the pixel definition portion 211, it is possible to avoid the light shielding portion 31 blocking an excessively large area that affects the symmetry of the left-right viewing angles of the display panel.

[0065] In some embodiments, a width w1 of the light shielding portion 31 is smaller than a width w2 of the pixel defining portion 211 .

[0066] See also Figure 1 The width w1 of the shading portion 31 is smaller than the width w2 of the pixel defining portion 211 , and the edge of the pixel defining portion 211 protrudes from the edge of the shading portion 31 , so as to avoid the shading area of ​​the shading portion 31 being too large to affect the symmetry of the left and right viewing angles of the display panel.

[0067] In some embodiments, the width w1 of the light shielding portion 31 is greater than or equal to 2 microns and less than or equal to 8 microns, and the width w2 of the pixel defining portion 211 is greater than 2 microns and less than or equal to 14 microns. For example, the width w1 of the light shielding portion 31 is 2 microns, and the width w2 of the pixel defining portion 211 is 3 microns; or, the width w1 of the light shielding portion 31 is 5 microns, and the width w2 of the pixel defining portion 211 is 8 microns; or, the width w1 of the light shielding portion 31 is 8 microns, and the width w2 of the pixel defining portion 211 is 14 microns.

[0068] In some embodiments, see Figure 1 , the light shielding portion 31 is aligned with the center of the aligned pixel definition portion 211. It should be noted that the center of the light shielding portion 31 refers to the midpoint of the light shielding portion 31 in the width direction, and the center of the pixel definition portion 211 refers to the midpoint of the pixel definition portion 211 in the width direction, so that the distances between the opposite side edges of the light shielding portion 31 and the opposite side edges of the pixel definition portion 211 can be the same, thereby ensuring the symmetry of the left and right viewing angles of the display panel.

[0069] In some embodiments, see Figure 4 and Figure 5 , Figure 4 A schematic diagram of an opposing substrate provided in an embodiment of the present application, Figure 5This is a bottom view of the opposite substrate provided in an embodiment of the present application. The color filter layer 41 includes a plurality of filter portions 410. The plurality of filter portions 410 are in a strip shape and are alternately and repeatedly arranged along the first direction X.

[0070] In some embodiments, see Figure 4 and Figure 5 The filter portion 410 includes a red filter portion 411, a green filter portion 412 and a blue filter portion 413. The red filter portion 411, the green filter portion 412 and the blue filter portion 413 are all in a long strip structure and extend along the second direction Y. The red filter portion 411, the green filter portion 412 and the blue filter portion 413 are alternately and repeatedly arranged in sequence along the first direction X.

[0071] In some embodiments, the orthographic projection of the edge of the light filtering portion 410 on the light shielding pattern 3 is located within the light shielding portion 31 .

[0072] See also Figures 3 to 5 Taking the red filter portion 411 and the green filter portion 412 as examples, the orthographic projections of the opposite side edges of the red filter portion 411 on the shading pattern 3 are located in the corresponding shading portion 31, and the orthographic projections of the opposite side edges of the green filter portion 412 on the shading pattern 3 are located in the corresponding shading portion 31. In this way, it can be avoided that the light emitted by the light-emitting layer 24 leaks out from the edge of the filter portion 410, causing light leakage or color mixing between adjacent filter portions 410 of different colors.

[0073] In some embodiments, see Figure 1 The opposite substrate 4 further includes a protective layer 42, and the filter portion 410 is disposed on a side of the protective layer 42 close to the light shielding pattern 3. Since the light shielding pattern 3 is not formed on the protective layer 42, the filter portion 410 of the color filter layer 41 is directly manufactured on the protective layer 42, which can not only improve the flatness of the color filter layer 41, but also reduce the process difficulty of the color filter layer 41.

[0074] In some embodiments, see Figure 1 The material of the protective layer 42 is glass, that is, the protective layer 42 can also be called a glass cover.

[0075] In some embodiments, see Figure 1 The opposite substrate 4 further includes a surface film layer 43, and the surface film layer 43 can be selected from any one or a combination of films such as anti-reflection films and anti-fingerprint films.

[0076] In some embodiments, see Figure 1The display panel further includes a filling layer 6, which is disposed between the filter portion 410 and the light shielding pattern 3, and is used to fill the gap between the opposing substrate 4 and the film layer of the array substrate 1 close to the opposing substrate 4. Since the light shielding pattern 3 is not formed on the protective layer 42, the color filter layer 41 is directly formed on the protective layer 42, which can improve the flatness of the surface of the color filter layer 41, and is conducive to better diffusion of the filling layer 6 between the color filter layer 41 and the light shielding pattern 3, thereby improving the uniformity of the distribution of the filling layer 6 in the display panel, and reducing the risk of display abnormalities such as uneven display brightness due to uneven distribution of the filling layer 6.

[0077] In some embodiments, the display panel further includes a sealing layer 7 , and the sealing layer 7 is disposed on the periphery of the light shielding pattern 3 .

[0078] See also Figure 1 The sealing layer 7 is used to bond the counter substrate 4 to the array substrate 1, and seal the light-emitting device layer 2 and the light-shielding pattern 3 and other film layers between the counter substrate 4 and the array substrate 1, so as to improve the sealing effect of the display panel. The sealing layer 7 is arranged on the periphery of the light-emitting device layer 2, the encapsulation layer 5, the light-shielding pattern 3 and the filling layer 6, and the material of the sealing layer 7 is a sealant. In the actual preparation process, the light-shielding pattern 3 can be formed on the encapsulation layer 5 first, and then a circle of sealing layer 7 can be formed on the periphery of the light-emitting device layer 2, the encapsulation layer 5 and the light-shielding pattern 3, and then the filling layer 6 is coated on the light-shielding pattern 3, and finally the counter substrate 4 and the array substrate 1 are bonded.

[0079] In some embodiments, see Figure 6 , Figure 6 A schematic diagram of the structure of a second display panel provided in an embodiment of the present application, which has a structure similar to Figure 1 The structure of the display panel shown is substantially the same, except that the display panel further comprises a planar layer 8 , which is disposed on a surface of the second inorganic encapsulation layer 53 away from the array substrate 1 , and covers the light shielding pattern 3 .

[0080] It should be noted that, since the shading pattern 3 has a plurality of shading portions 31 and a plurality of first openings 32, when a filling glue is applied on the shading pattern 3 to form a filling layer 6, some of the first openings 32 may not be filled with the filling glue, and there is a difference in transmittance between the first openings 32 and other first openings 32 filled with the filling glue, which ultimately causes the display panel to have optical defects such as uneven display brightness, resulting in a reduction in the production yield of the display panel. In this embodiment, a flat layer 8 is added to the surface of the second inorganic encapsulation layer 53 away from the array substrate 1. The material of the flat layer 8 is a transparent organic material. By utilizing the good leveling property of the transparent organic material, the probability of the first opening 32 not being filled can be reduced, and the surface of the flat layer 8 away from the array substrate 1 is a flat surface, so that the uniformity of the distribution of the filling layer 6 can be improved, thereby improving the uniformity of the brightness of the display panel and improving the production yield of the display panel.

[0081] In some embodiments, see Figure 7 , Figure 7 A schematic diagram of the structure of a third display panel provided in an embodiment of the present application, which has a structure similar to Figure 1 The structure of the display panel shown is substantially the same, except that the light shielding pattern 3 is disposed on the surface of the first inorganic encapsulation layer 51 away from the light emitting device layer 2. Figure 1 The embodiment shown in the figure can further reduce the distance between the shading pattern 3 and the pixel definition layer 21 and the light-emitting layer 24 in the thickness direction of the display panel, so that the shading area of ​​the light-emitting layer 24 blocked by the shading pattern 3 can be further reduced, thereby further improving the viewing angle symmetry and viewing angle of the display panel.

[0082] In some embodiments, see Figure 7 The shading pattern 3 is arranged on the surface of the first inorganic encapsulation layer 51 away from the light-emitting device layer 2. The thickness of the shading pattern 3 is less than the thickness of the first organic encapsulation layer 52. The thickness of the first organic encapsulation layer 52 is greater than 4 microns. The first organic encapsulation layer 52 can completely cover the shading pattern 3 and ensure the flatness of the upper surface of the first organic encapsulation layer 52. It will not affect the film-forming effect of the second inorganic encapsulation layer 53, so that the viewing angle symmetry and viewing angle of the display panel can be improved while ensuring that the encapsulation effect of the encapsulation layer 5 is not affected.

[0083] In some embodiments, see Figure 8 , Figure 8 A schematic diagram of the structure of a fourth display panel provided in an embodiment of the present application, which has a structure similar to Figure 1 The structures of the display panels shown are substantially the same, except that the light shielding pattern 3 is disposed on the surface of the first organic encapsulation layer 52 away from the first inorganic encapsulation layer 51. Figure 1The embodiment shown in the figure can further reduce the distance between the shading pattern 3 and the pixel definition layer 21 and the light-emitting layer 24 in the thickness direction of the display panel, so that the shading area of ​​the light-emitting layer 24 blocked by the shading pattern 3 can be further reduced, thereby further improving the viewing angle symmetry and viewing angle of the display panel.

[0084] In some embodiments, see Figure 8 The shading pattern 3 is arranged on the surface of the first organic encapsulation layer 52 away from the first inorganic encapsulation layer 51, and the second inorganic encapsulation layer 53 has step coverage, which can completely cover the shading pattern 3 and the organic encapsulation layer 52, and will not affect the encapsulation effect of the second inorganic encapsulation layer 53 and the organic encapsulation layer 52. Therefore, the viewing angle symmetry and viewing angle of the display panel can be improved while ensuring that the encapsulation effect of the encapsulation layer 5 is not affected.

[0085] In some embodiments, see Fig. 9 , Fig. 9 A schematic diagram of the structure of a fifth display panel provided in an embodiment of the present application, which has a structure similar to Figure 8 The structure of the display panel shown is roughly the same, with the difference that: the encapsulation layer includes a second organic encapsulation layer 54, the shading pattern 3 is arranged on the surface of the first organic encapsulation layer 52 away from the light-emitting device layer 2, the second organic encapsulation layer 54 is arranged on the surface of the first organic encapsulation layer 52 away from the light-emitting device layer 2, and the second organic encapsulation layer 54 covers the shading pattern 3.

[0086] See also Fig. 9 By adding a second organic encapsulation layer 54 on the surface of the first organic encapsulation layer 52 away from the light-emitting device layer 2, the first opening in the light-shielding pattern 3 can be filled and the light-shielding pattern 3 can be covered by utilizing the leveling property of the organic material. The second organic encapsulation layer 54 can provide a flat surface for the subsequent deposition of the second inorganic encapsulation layer 53, ensure the compactness of the second inorganic encapsulation layer 53, and prevent the second inorganic encapsulation layer 53 from being deposited on an uneven surface and generating cracks, thereby improving the viewing angle symmetry and viewing angle of the display panel while ensuring that the encapsulation effect of the encapsulation layer is not affected.

[0087] In some embodiments, the thickness of the second organic encapsulation layer 54 is greater than the thickness of the shading pattern 3, wherein the thickness of the second organic encapsulation layer 54 is greater than or equal to 2 microns and less than or equal to 6 microns, and the thickness of the shading pattern 3 is greater than or equal to 1 micron and less than or equal to 2 microns. This ensures that the second organic encapsulation layer 54 can completely cover the shading pattern 3 and provides the second organic encapsulation layer 54 with a flat surface, thereby improving the viewing angle symmetry and viewing angle of the display panel while ensuring that the encapsulation effect of the encapsulation layer is not affected.

[0088] In some embodiments, the thickness of the first organic encapsulating layer 52 is greater than or equal to 2 micrometers and less than or equal to 6 micrometers.
