Display panel and display device

[0001] This invention claims priority to Chinese Patent Application No. 202411997388.7, filed with the State Intellectual Property Office of China on December 31, 2024, entitled “Display Panel and Display Device”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0003] In today's digital age, information security and privacy protection are receiving increasing attention, leading to the emergence of privacy protection features on display panels, which have become an important characteristic of many electronic devices.

[0004] However, the existing structural design of privacy display panels imposes significant limitations on the aperture ratio design of privacy pixels, making it difficult to improve the aperture ratio of privacy pixels. Summary of the Invention

[0005] This invention provides a display panel and display device for improving the aperture ratio of privacy pixels.

[0006] In a first aspect, embodiments of the present invention provide a display panel, comprising:

[0007] Substrate;

[0008] Pixel layer, including the first pixel;

[0009] An encapsulation layer is located on the side of the pixel layer away from the substrate, and the encapsulation layer is a single-layer film structure;

[0010] Multiple masking structures are provided, each masking structure including a first masking portion and a second masking portion; wherein the first masking portion is located on the side of the encapsulation layer away from the substrate, and a first opening is provided between the first masking portions of adjacent masking structures; the second masking portion is located on the side of the first masking portion away from the substrate, and a second opening is provided between the second masking portions of adjacent masking structures; and in a direction perpendicular to the plane of the substrate, the first pixel, the first opening, and the second opening at least partially overlap.

[0011] Secondly, based on the same inventive concept, embodiments of the present invention also provide a method for manufacturing a display panel, comprising:

[0012] A pixel layer is formed on one side of the substrate, the pixel layer including a first pixel;

[0013] An encapsulation layer is formed on the pixel layer, and the encapsulation layer is a single-layer film structure;

[0014] A shielding structure is formed on the encapsulation layer, the shielding structure including a first shielding portion and a second shielding portion; wherein, the first shielding portion is located on the side of the encapsulation layer away from the substrate, and a first opening is formed between adjacent first shielding portions of the shielding structure; the second shielding portion is located on the side of the first shielding portion away from the substrate, and a second opening is formed between adjacent second shielding portions of the shielding structure; and in a direction perpendicular to the plane of the substrate, the first pixel, the first opening and the second opening at least partially overlap.

[0015] Thirdly, based on the same inventive concept, embodiments of the present invention also provide a display device, including the aforementioned display panel.

[0016] The technical solution provided by the embodiments of the present invention has the following beneficial effects:

[0017] The display panel provided in this embodiment of the invention adopts a single-layer packaging design. The packaging structure in this method consists of a very thin inorganic layer with a very small film thickness. Therefore, when a first blocking portion is disposed on top of this layer, the vertical distance between the first blocking portion and the first pixel can be greatly reduced, making the first blocking portion very close to the first pixel. This allows the first blocking portion to block light emitted from the first pixel at a larger angle. Simultaneously, a second blocking portion is disposed above the first blocking portion. Compared to the first blocking portion, the vertical distance between the second blocking portion and the first pixel is slightly larger. This second blocking portion can block light emitted from the first pixel at a smaller angle.

[0018] By employing the technical solution provided in the embodiments of the present invention, under the condition that the display panel achieves the same privacy angle, the spacing between adjacent first pixels can be reduced, thereby increasing the aperture ratio of the first pixel and effectively extending the lifespan of the first pixel.

[0045] To better understand the technical solution of the present invention, the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] It should be understood that the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0047] The terminology used in the embodiments of this invention is for the purpose of describing particular embodiments only and is not intended to limit the invention. The singular forms “a,” “the,” and “the” as used in the embodiments of this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0048] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0049] Before describing the technical solutions provided by the embodiments of the present invention, the present invention first introduces the structure of the display panel in the related art.

[0050] As shown in Figure 1, which is a schematic diagram of a display panel in the related art, the display panel includes a substrate 101, a privacy pixel 102 located on one side of the substrate 101, an encapsulation layer 103 located on the side of the privacy pixel 102 away from the substrate 101, and a shielding structure 104 located on the side of the encapsulation layer 103 away from the substrate 101.

[0051] The encapsulation layer 103 includes a first inorganic encapsulation layer 1031, an organic encapsulation layer 1032, and a second inorganic encapsulation layer 1033 stacked together. An opening 105 is provided between adjacent shielding structures 104, and the opening 105 overlaps with the privacy pixel 102 in a direction perpendicular to the plane of the substrate 101.

[0052] In this structure, a relatively thick encapsulation layer 103 separates the blocking structure 104 from the privacy pixel 102, and the blocking structure 104 and the privacy pixel 102 are far apart vertically. If the blocking structure 104 is to block the large-angle light emitted by the privacy pixel 102, the adjacent privacy pixels 102 need to be spaced sufficiently, which leads to a decrease in the aperture ratio of the privacy pixel 102 and a significant reduction in the lifespan of the privacy pixel 102.

[0053] For example, the thicknesses of the first inorganic encapsulation layer 1031 and the second inorganic encapsulation layer 1033 are 1 μm, the thickness of the organic encapsulation layer 1032 is 17 μm, and the width m1 of the privacy pixel 102 is 10 μm and the width m2 of the blocking structure 104 is 15 μm along the first direction x, so that light beyond 45° can be blocked and privacy protection for viewing angles above 45° can be achieved.

[0054] Based on this, this embodiment of the invention proposes that the shielding structure 104 can be designed as a double-layer structure. As shown in Figure 2, which is a schematic diagram of a display panel provided in this embodiment of the invention, the shielding structure 104 includes a first shielding portion 1041 and a second shielding portion 1042. The side of the encapsulation layer 103 away from the substrate also includes a light extraction layer 106, which includes a dimming portion 1061 and a dimming layer 1062 covering the dimming portion 1061. The dimming layer 1062 is spaced between the first shielding portion 1041 and the second shielding portion 1042. However, the improvement effect of this structure is still not good, and it is difficult to significantly improve the aperture ratio of the privacy pixel.

[0055] In this regard, the present invention provides a display panel, as shown in FIG3. FIG3 is a schematic diagram of another structure of the display panel provided in the embodiment of the present invention. The display panel includes a substrate 1, a pixel layer 2, an encapsulation layer 3 and a plurality of shielding structures 4.

[0056] Among them, pixel layer 2 includes first pixel 5, which is a privacy pixel.

[0057] The encapsulation layer 3 is located on the side of the pixel layer 2 away from the substrate 1, and the encapsulation layer 3 is a single-layer film structure.

[0058] The shielding structure 4 includes a first shielding portion 6 and a second shielding portion 7. The first shielding portion 6 is located on the side of the encapsulation layer 3 away from the substrate 1, specifically on the surface of the encapsulation layer 3 away from the substrate 1. That is, the first shielding portion 6 is adjacent to the encapsulation layer 3 without any other film layer separating them, and a first opening 8 is formed between adjacent first shielding portions 6 of the shielding structure 4. The second shielding portion 7 is located on the side of the first shielding portion 6 away from the substrate 1, and a second opening 9 is formed between adjacent second shielding portions 7 of the shielding structure 4. In a direction perpendicular to the plane of the substrate 1, the first pixel 5, the first opening 8, and the second opening 9 at least partially overlap.

[0059] Unlike the aforementioned structures, the display panel provided in this embodiment of the invention adopts a single-layer encapsulation design. This encapsulation method uses a very thin inorganic layer with a very small film thickness. Therefore, when the first blocking part 6 is disposed on top of it, the vertical distance between the first blocking part 6 and the first pixel 5 can be greatly reduced, making the first blocking part 6 very close to the first pixel 5. The first blocking part 6 can block light emitted from the first pixel 5 at a larger angle. Simultaneously, a second blocking part 7 is disposed above the first blocking part 6. Compared to the first blocking part 6, the vertical distance between the second blocking part 7 and the first pixel 5 is slightly larger. The second blocking part 7 can block light emitted from the first pixel 5 at a smaller angle.

[0060] Using the technical solution provided by the embodiments of the present invention, as shown in Figure 4, Figure 4 is a size comparison diagram of the first pixel 5 provided by the embodiments of the present invention. Under the condition that the display panel reaches the same privacy angle, the spacing between adjacent first pixels 5 can be reduced, so that the aperture ratio of the first pixel 5 can be greater. For example, along the first direction x, the width m1 of the first pixel 5 can be greater than or equal to the width m2 of the blocking structure 4, thereby effectively extending the lifespan of the first pixel 5.

[0061] In one feasible implementation, the encapsulation layer 3 is an inorganic layer, which may specifically include oxide materials, such as alumina materials.

[0062] In this embodiment of the invention, the encapsulation layer 3 can be formed by atomic layer deposition (ALD) process. The single-layer encapsulation film formed by this process has high density and can effectively block the intrusion of external moisture, oxygen, impurities and other substances, thereby achieving a good encapsulation effect.

[0063] In one feasible implementation, referring to Figure 3, the film thickness h of the encapsulation layer 3 is less than 1 μm. Further, 30 nm ≤ h ≤ 100 nm.

[0064] The encapsulation layer 3 with this thickness is very thin. When the first blocking part 6 is placed on top of it, the vertical distance between the first blocking part 6 and the first pixel 5 can be greatly compressed, so that the first blocking part 6 can block the light emitted by the first pixel 5 at a larger angle. Thus, under the condition that the display panel achieves the same privacy angle, the aperture ratio of the first pixel 5 can be increased to a greater extent.

[0065] In one feasible implementation, as shown in Figures 5 and 6, Figure 5 is a top view of a display panel provided in an embodiment of the present invention, and Figure 6 is another top view of a display panel provided in an embodiment of the present invention. The pixel layer 2 includes a first display unit 10, and the first display unit 10 includes at least two first pixels 5 of the same color arranged along a first direction x.

[0066] Referring to Figure 7, pixel layer 2 also includes a second pixel 11, which is a shared pixel, and the area of ​​the second pixel 11 is larger than the area of ​​the first pixel 5 of the same color.

[0067] On the plane where the substrate 1 is located, the orthographic projection of the first pixel 5 has at least the orthographic projection of the occlusion structure 4 on the opposite side of the first direction x.

[0068] Taking the first direction x as the left and right viewing angle and the display panel implementing left and right privacy protection as an example: The display panel has a privacy protection mode and a sharing mode. In sharing mode, the second pixel 11 emits light, and the first pixel 5 can emit light or not, allowing the user to view the image normally from both the frontal and left / right viewing angles. In privacy protection mode, the first pixel 5 emits light, and the second pixel 11 does not emit light. The light emitted by the first pixel 5 from the left and right viewing angles is blocked by the blocking structures 4 on its left and right sides, thus allowing the user to view the image from the frontal view, but not from the left / right viewing angles, enabling the display panel to achieve privacy protection from both left and right viewing angles.

[0069] The first display unit 10 is a privacy display unit. This structure can be understood as dividing the pixels in the first display unit 10 into at least two smaller privacy pixels (first pixels 5) arranged along the first direction x through pixel segmentation. Thus, each privacy pixel has a blocking structure 4 on both its left and right sides, allowing the light emitted by each privacy pixel from both sides to be blocked to a greater extent by the blocking structures 4, resulting in better privacy protection from both angles. Compared to directly designing the first pixel 5 to have the same area as the second pixel 11, this pixel segmentation design allows the display panel to achieve a better privacy protection effect.

[0070] In one optional specific structure, the first pixel 5 includes a first type of first pixel 5-1, a second type of first pixel 5-2, and a third type of first pixel 5-3. The second pixel 11 includes a first type of second pixel 11-1, a second type of second pixel 11-2, and a third type of second pixel 11-3.

[0071] In this configuration, the first pixel 5-1 of the first type and the second pixel 11-1 of the first type have the same color; the first pixel 5-2 of the second type and the second pixel 11-2 of the second type have the same color; and the first pixel 5-3 of the third type and the second pixel 11-3 of the third type have the same color. For example, the color of the first pixel 5-3 of the third type is blue, and one of the first pixels 5-1 and the second pixel 5-2 of the first type is red and the other is green.

[0072] The first display unit 10 includes a first type of first display unit 10-1, a second type of first display unit 10-2, and a third type of first display unit 10-3. The first type of first display unit 10-1 includes at least two first type first pixels 5-1 arranged along a first direction x; the second type of first display unit 10-2 includes at least two second type first pixels 5-2 arranged along the first direction x; and the third type of first display unit 10-3 includes at least two third type first pixels 5-3 arranged along the first direction x.

[0073] The display panel includes multiple repeating units 60. Each repeating unit 60 includes a first type of first display unit 10-1, a first type of second pixel 11-1, a second type of first display unit 10-2, and a second type of second pixel 11-2 arranged along a second direction y, and includes a third type of first display unit 10-3 and a third type of second pixel 11-3 arranged along the second direction y. The second direction y intersects with the first direction x.

[0074] In one structure, referring to Figure 5, in the repeating unit 60, along the first direction x, the third type first display unit 10-3 overlaps with the first type first display unit 10-1, and two third type first pixels 5-3 and first type first pixels 5-1 that are close to each other in the third type first display unit 10-3 and the first type first display unit 10-1 can share a occlusion structure 4.

[0075] That is, in this structure, the occlusion structure 4 includes a first sub-occlusion structure 81, a second sub-occlusion structure 82, a third sub-occlusion structure 83 and a fourth sub-occlusion structure 84.

[0076] Specifically, in the direction perpendicular to the plane of substrate 1, the orthographic projection of the first sub-blocking structure 81 is located between the orthographic projections of two adjacent first-class first pixels 5-1, the orthographic projection of the second sub-blocking structure 82 is located on opposite sides of the orthographic projection of the second-class first pixel 5-2 in the first direction x, the orthographic projection of the third sub-blocking structure 83 is located between the orthographic projections of two adjacent third-class first pixels 5-3, and the orthographic projection of the fourth sub-blocking structure 84 is located between the orthographic projections of adjacent first-class first pixels 5-1 and third-class first pixels 5-3. The fourth sub-blocking structure 84 is used to block the light emitted by the first-class first pixels 5-1 and the third-class first pixels 5-3.

[0077] When the color of the third type first pixel 5-3 is blue, the size of the third type first pixel 5-3 in the second direction y is usually larger than the size of the first type first pixel 5-1 and the second type first pixel 5-2 in the second direction y.

[0078] To ensure that the fourth sub-occlusion structure 84 and the third sub-occlusion structure 83 can effectively block the light of the third type of first pixel 5-3, along the second direction y, the width of the fourth sub-occlusion structure 84 can be set to be greater than the width of the first sub-occlusion structure 81 and the second sub-occlusion structure 82, and the width of the third sub-occlusion structure 83 can be set to be greater than the width of the first sub-occlusion structure 81 and the second sub-occlusion structure 82.

[0079] Furthermore, along the first direction x, when the third type of first display unit 10-3 only partially overlaps with the first type of first display unit 10-1, the width of the fourth sub-occlusion structure 84 in the second direction y can be set to be greater than the size of the third type of first pixel 5-3 in the second direction y. This ensures that along the first direction x, the first type of first pixel 5-1 can completely overlap with the fourth sub-occlusion structure 84, and the third type of first pixel 5-3 can also completely overlap with the fourth sub-occlusion structure 84. The fourth sub-occlusion structure 84 can effectively block the light from both the first type of first pixel 5-1 and the third type of first pixel 5-3 on its two sides. At this time, the width of the third sub-occlusion structure 83 in the second direction y can be consistent with the width of the fourth sub-occlusion structure 84 in the second direction y.

[0080] For example, along the second direction y, the width of the fourth sub-occlusion structure 84 is 1.5 times or more the width of the first sub-occlusion structure 81.

[0081] Furthermore, referring again to Figure 5, along the first direction x, the third type of first display unit 10-3 and the first type of second pixel 11-1 do not overlap, and the fourth sub-occlusion structure 84 and the first type of second pixel 11-1 do not overlap, so as to prevent the fourth sub-occlusion structure 84 from affecting the normal light output of the first type of second pixel 11-1.

[0082] Furthermore, referring again to Figure 5, along the first direction x, the third type of second pixel 11-3 overlaps with the second type of second pixel 11-2, but does not overlap with the second type of first display unit 10-2. This can prevent the second sub-occlusion structure 82 from affecting the light emission of the third type of second pixel 11-3.

[0083] Alternatively, in another structure, the first pixels 5 of different types may not share the occlusion structure 4. For example, referring to FIG6, along the first direction x, the third type first display unit 10-3 overlaps with the first type first display unit 10-1, but the two third type first pixels 5-3 and the first type first pixels 5-1 that are close to each other in the third type first display unit 10-3 and the first type first display unit 10-1 do not share the occlusion structure 4.

[0084] That is, in this structure, the occlusion structure 4 includes a first sub-occlusion structure 81, a second sub-occlusion structure 82 and a third sub-occlusion structure 83.

[0085] Specifically, in the direction perpendicular to the plane of substrate 1, the orthographic projection of the first sub-shading structure 81 is located on the opposite side of the orthographic projection of the first type of first pixel 5-1 in the first direction x, the orthographic projection of the second sub-shading structure 82 is located on the opposite side of the orthographic projection of the second type of first pixel 5-2 in the first direction x, and the orthographic projection of the third sub-shading structure 83 is located on the opposite side of the orthographic projection of the third type of first pixel 5-3 in the first direction x.

[0086] When the color of the third type first pixel 5-3 is blue, the size of the third type first pixel 5-3 in the second direction y is usually larger than the size of the first type first pixel 5-1 and the second type first pixel 5-2 in the second direction y.

[0087] In order to ensure that the third sub-occlusion structure 83 can effectively block the light of the third type of first pixel 5-3, the width of the third sub-occlusion structure 83 can be set to be greater than the width of the first sub-occlusion structure 81 and the second sub-occlusion structure 82 along the second direction y.

[0088] Furthermore, referring to Figures 6 and 7, Figure 7 is a cross-sectional view of Figure 6 along the A1-A2 direction. Along the first direction x, at least a portion of the second pixel 11 overlaps with the first pixel 5. For example, referring to Figure 6, along the first direction x, the first type of second pixel 11-1 overlaps with the third type of first pixel 5-3, and the third type of second pixel 11-3 overlaps with the second type of first pixel 5-2.

[0089] The occlusion structure 4 includes a first occlusion structure 12. On the plane where the substrate 1 is located, the orthographic projection of the first occlusion structure 12 is located between the orthographic projection of the second pixel 11 and the orthographic projection of the first pixel 5. Furthermore, the distance k1 between the orthographic projection of the first occlusion structure 12 and the orthographic projection of the second pixel 11 is greater than the distance k2 between the orthographic projection of the first occlusion structure 12 and the orthographic projection of the first pixel 5.

[0090] For example, referring to FIG6, the first occlusion structure 12 includes a third sub-occlusion structure 83. On the plane where the substrate 1 is located, the orthographic projection of the third sub-occlusion structure 83 is located between the orthographic projection of the first type second pixel 11-1 and the orthographic projection of the third type first pixel 5-3, and the distance between the orthographic projection of the third sub-occlusion structure 83 and the orthographic projection of the first type second pixel 11-1 is greater than the distance between the orthographic projection of the third sub-occlusion structure 83 and the orthographic projection of the third type first pixel 5-3.

[0091] The occlusion structure 12 includes a second sub-occlusion structure 82. On the plane of the substrate 1, the orthographic projection of the second sub-occlusion structure 82 is located between the orthographic projection of the third type second pixel 11-3 and the orthographic projection of the second type first pixel 5-2, and the distance between the orthographic projection of the second sub-occlusion structure 82 and the orthographic projection of the third type second pixel 11-3 is greater than the distance between the orthographic projection of the second sub-occlusion structure 82 and the orthographic projection of the second type first pixel 5-2.

[0092] Setting the distance between the first occlusion structure 12 and the second pixel 11 to be greater than the distance between the first occlusion structure and the first pixel 5 allows the first occlusion structure 12 to block the oblique angle light emitted by the first pixel 5 without blocking the light emitted by the second pixel 11 on one side, thereby avoiding affecting the display effect in the sharing mode.

[0093] In one feasible implementation, as shown in FIG8, FIG8 is another structural schematic diagram of the display panel provided in the embodiment of the present invention, wherein there is a gap between the first shielding part 6 and the second shielding part 7 along the direction perpendicular to the plane where the substrate 1 is located.

[0094] That is, there are other film layers between the first blocking part 6 and the second blocking part 7. In this way, by designing parameters such as the number and thickness of the film layers between the first blocking part 6 and the second blocking part 7, the longitudinal distance between the second blocking part 7 and the first pixel 5 can be flexibly adjusted, thereby adjusting the minimum light-blocking angle that the blocking structure 4 can have, and improving the flexibility of the privacy angle design of the display panel. Therefore, under the condition that the display panel achieves the same privacy angle, the spacing between adjacent first pixels 5 can be reduced, so that the aperture ratio of the first pixel 5 can be increased.

[0095] In one possible implementation, referring again to FIG8, the display panel further includes a first film layer 13, which is located between the first blocking portion 6 and the second blocking portion 7, and the first film layer 13 includes a touch layer 14 and / or a light extraction layer 15.

[0096] Specifically, the touch layer 14 may include a first electrode layer 16, a first insulating layer 17, a second electrode layer 18, and a second insulating layer 19 stacked along a direction away from the substrate 1. One of the first electrode layer 16 and the second electrode layer 18 includes a touch electrode, and the other includes a touch signal line.

[0097] The light extraction layer 15 may specifically include multiple dimming units 20 and a dimming layer 21 covering the dimming units 20. In a direction perpendicular to the plane of the substrate 1, the first pixel 5 and the second pixel 11 overlap with the dimming units 20. For example, in a direction perpendicular to the plane of the substrate 1, there may be a gap between the edge of the orthographic projection of the first pixel 5 and the edge of the orthographic projection of the dimming unit 20, such a gap may be set to approximately 2.02 μm. The dimming units 20 and the dimming layer 21 have different refractive indices; for example, the refractive index of the dimming unit 20 is greater than that of the dimming layer 21. After the light emitted by the first pixel 5 and the second pixel 11 enters the light extraction layer 15, it is refracted at the interface between the dimming units 20 and the dimming layer 21, thereby converting large-angle light into small-angle light and improving the brightness of the emitted light at a normal viewing angle.

[0098] The display panel also includes an organic spacer layer 22, which is located between the first film layer 13 and the first shielding portion 6.

[0099] In the film structure of a display panel, the thickness of the organic layer is usually much greater than that of the inorganic layer. An organic spacer layer 22 is provided between the first film layer 13 and the first blocking portion 6. On one hand, the organic spacer layer 22, positioned between the touch layer 14 and the pixel layer 2, can reduce mutual interference between touch signals and display signals; and / or, the organic spacer layer 22, positioned between the light extraction layer 15 and the pixel layer 2, keeps the light extraction layer 15 and the pixel layer 2 far apart, allowing more oblique light emitted by the first pixel 5 and the second pixel 11 to enter the interface between the dimming portion 20 and the dimming layer 21, further improving the light extraction rate. On the other hand, the second blocking portion 7, being far apart from the first pixel 5, can block light emitted by the first pixel 5 at smaller angles, improving the privacy protection effect.

[0100] Furthermore, the thickness of the organic spacer layer 22 can be set to be greater than 10 μm so that there is sufficient spacing between the pixel layer 2 and the touch layer 14, the light extraction layer 15, and the second blocking portion 7.

[0101] In one feasible implementation, the dielectric constant of the organic spacer layer 22 is ε1, 2.3≤ε1≤3. The low dielectric constant of this organic spacer layer 22 can further reduce the mutual interference between the touch layer 14 and the pixel layer 2, and ensure touch performance.

[0102] In one feasible implementation, the organic spacer layer 22 comprises an organic photoresist material.

[0103] The organic spacer layer 22 comprises an organic photoresist material, meaning that the organic spacer layer 22 can be formed using an etching process. As shown in Figure 9, which is a schematic diagram of another structure of the display panel provided in this embodiment of the invention, the etched organic spacer layer 22 has a uniform film thickness and superior film flatness. More specifically, the display panel includes a display area AA and a non-display area NAA located on one side of the display area AA. The organic spacer layer 22 includes a first portion 23 located in the non-display area NAA and a second portion 24 located at least in the display area AA, wherein the film thickness of the first portion 23 is equal to the film thickness of the second portion 24.

[0104] Alternatively, in another feasible implementation, the organic spacer layer 22 can also be formed using an inkjet printing process. During inkjet printing, ink droplets in the central region can overlap and spread relatively evenly, while in the edge regions, the deposition distribution of droplets changes, resulting in a smaller film thickness in the edge regions.

[0105] As shown in Figure 10, which is a schematic diagram of another structure of a display panel provided in an embodiment of the present invention, the display panel includes a display area AA and a non-display area NAA located on one side of the display area AA. The organic spacer layer 22 includes a first portion 23 located in the non-display area NAA and a second portion 24 located at least in the display area AA. The film thickness of the first portion 23 is less than the film thickness of the second portion 24. For example, the film thickness of the first portion 23 decreases along the direction from the display area AA to the non-display area NAA.

[0106] The film layer formed by inkjet printing can have a greater film thickness. When inkjet printing forms the organic spacer layer 22, the film thickness of the organic spacer layer 22 can be set within a wider range, which helps to adjust the longitudinal distance between the second blocking part 7 and the first pixel 5 more flexibly, and adjust the light blocking angle of the second blocking part 7.

[0107] Furthermore, referring again to Figure 10, the display panel also includes a barrier dam 25 located in the non-display area NAA and between the organic spacer layer 22 and the outer edge of the display panel.

[0108] During the printing process, after the ink is ejected from the printhead, it tends to spread naturally under the influence of surface tension and other factors. By setting the blocking dam 25, the ink can be prevented from exceeding the set printing area, thus limiting the ink to a specific range and ensuring that the ink is deposited according to the preset pattern or area.

[0109] It should be noted that, unlike printing to form the organic spacer layer 22, when etching to form the organic spacer layer 22, the organic photoresist material has almost no fluidity during the process, so there is no need to set a barrier dam 25 near the outer edge of the display panel.

[0110] In one feasible implementation, referring again to FIG9, the orthographic projection of the organic spacer layer 22 on the plane of the substrate 1 overlaps with the orthographic projection of the encapsulation layer 3. In one process, after the organic spacer layer 22 is formed, the organic spacer layer 22 can be regarded as a mask, and the encapsulation layer 3 in the area outside the area covered by the organic spacer layer 22 can be etched away, so that the edge of the encapsulation layer 3 is flush with the edge of the organic spacer layer 22.

[0111] When the edges of the encapsulation layer 3 and the organic spacer layer 22 are flush, the stress can be more evenly distributed across the entire encapsulation structure when subjected to external forces such as thermal expansion and contraction or mechanical vibration. This reduces stress concentration caused by uneven edges, thereby helping to prevent cracks, peeling, and other damage to the encapsulation layer 3 or the organic spacer layer 22 due to stress concentration, and improving the structural stability of the display panel.

[0112] In one feasible implementation, as shown in FIG11, FIG11 is another structural schematic diagram of the display panel provided in the embodiment of the present invention, along the first direction x, the width of the first blocking part 6 is greater than the width of the second blocking part 7.

[0113] That is, along the first direction x, the width of the first blocking part 6 is a1, and the width of the second blocking part 7 is a2. For example, the width a1 of the first blocking part 6 can be designed to be 14μm, 16μm, etc., and the width a2 of the second blocking part 7 can be designed to be 10μm, etc.

[0114] In the shielding structure 4, the first shielding part 6 is relatively close to the pixel layer 2. The first shielding part 6 is mainly used to block the light emitted by the first pixel 5 at a larger angle. Therefore, the first shielding part 6 largely determines the maximum privacy angle that the display panel can achieve. Furthermore, the width of the first shielding part 6 will significantly affect the range of light angles that the first shielding part 6 can block. Therefore, in this embodiment of the invention, the widths of the first shielding part 6 and the second shielding part 7 can be differentiated, with the first shielding part 6 being set wider. This allows the first shielding part 6 to block light at a larger angle, thereby enabling the display panel to achieve a wider privacy angle range.

[0115] Further, referring to Figure 11, on the plane where the substrate 1 is located, the distance between the edge of the orthographic projection of the first blocking part 6 and the edge of the orthographic projection of the first pixel 5 is x1, x1≥0, so as to avoid the first blocking part 6 from blocking the first pixel 5, and the distance between the edge of the orthographic projection of the second blocking part 7 and the edge of the orthographic projection of the light-emitting layer 26 is x2, x2>x1.

[0116] In one feasible implementation, as shown in FIG12, FIG12 is another structural schematic diagram of the display panel provided in the embodiment of the present invention. The first pixel 5 includes a light-emitting layer 26, and the light-emitting layer 26 includes a first top surface 27 away from the substrate 1.

[0117] The first shielding portion 6 includes a first bottom surface 28 near the substrate 1, and the second shielding portion 7 includes a second bottom surface 29 near the substrate 1.

[0118] The distance between the first top surface 27 and the first bottom surface 28 in the direction perpendicular to the plane of the substrate 1 is d1, and the distance between the first top surface 27 and the second bottom surface 29 in the direction perpendicular to the plane of the substrate 1 is d2.

[0119] In this embodiment of the invention, the first blocking part 6 is located above the encapsulation layer 3. Since the encapsulation layer 3 in this embodiment is a single-layer encapsulation, the longitudinal distance d1 between the first blocking part 6 and the light-emitting layer 26 is small, close to the film thickness of the encapsulation layer 3. Based on this, when setting the longitudinal distance d2 between the second blocking part 7 and the light-emitting layer 26, by setting the minimum value of the ratio between d2 and d1 to 10, it can be ensured that the second blocking part 7 and the light-emitting layer 26 are spaced sufficiently, so that the second blocking part 7 can block the small-angle light emitted by the first pixel 5, ensuring the minimum privacy angle that the display panel can have. Furthermore, setting the maximum value of the ratio between d2 and d1 to 50 can also prevent the second blocking part 7 from being too far away from the light-emitting layer 26, thus affecting the module thickness of the display panel.

[0120] For example, d1 < 1 μm, d2 > 10 μm, for example, 17 μm.

[0121] In one feasible implementation, referring to FIG8, the display panel further includes a light extraction layer 15, which is located between the first blocking portion 6 and the second blocking portion 7.

[0122] The light extraction layer 15 includes multiple dimming units 20 and a dimming layer 21 covering the dimming units 20. In a direction perpendicular to the plane of the substrate 1, the first pixel 5 overlaps with the dimming units 20. Each dimming unit 20 includes a first surface 30 and a second surface 31 facing each other, and a first inclined surface 32 connecting the first surface 30 and the second surface 31. In a direction perpendicular to the plane of the substrate 1, the second blocking portion 7 does not overlap with the first inclined surface 32.

[0123] For example, the distance p1 between the orthographic projection of the second shielding portion 7 on the substrate 1 and the orthographic projection of the first inclined surface 32 on the substrate 1 is about 1.6 μm.

[0124] In the light extraction layer 15, the refractive indices of the dimming unit 20 and the dimming layer 21 are different; for example, the refractive index of the dimming unit 20 is greater than that of the dimming layer 21. After the light emitted by the first pixel 5 and the second pixel 11 enters the light extraction layer 15, it is refracted at the interface between the dimming unit 20 and the dimming layer 21, thereby converting large-angle light into small-angle light and improving the brightness at a normal viewing angle. Therefore, the first inclined surface 32 of the dimming unit 20 is the main surface that acts on the light. When the second blocking part 7 is provided, it is ensured that the second blocking part 7 does not overlap with the first inclined surface 32, thus preventing the second blocking part 7 from affecting the dimming effect of the light extraction layer 15 and ensuring that the display panel has a high light extraction rate.

[0125] In one feasible implementation, as shown in FIG13, FIG13 is another structural schematic diagram of the display panel provided in the embodiment of the present invention. The film thickness of the first shielding part 6 is greater than the film thickness of the second shielding part 7, so that the sidewall of the first shielding part 6 blocks more oblique light and reduces the risk of oblique light passing through the adjacent second opening 9 and exiting the panel.

[0126] Alternatively, in another feasible implementation, as shown in FIG14, FIG14 is a schematic diagram of another structure of the display panel provided in the embodiment of the present invention, the film thickness of the second shielding part 7 is greater than the film thickness of the first shielding part 6.

[0127] In the shielding structure 4, the second shielding part 7 is mainly used to shield the light emitted by the first pixel 5 at a smaller angle. However, the film thickness of the second shielding part 7 significantly affects the range of light angles that it can block. Therefore, in this embodiment of the invention, the film thicknesses of the first shielding part 6 and the second shielding part 7 can be differentiated, making the second shielding part 7 thicker. This allows the sidewalls of the second shielding part 7 to block more light at smaller angles, thereby increasing the privacy viewing angle range of the display panel.

[0128] Furthermore, referring again to Figure 14, the film thickness of the first blocking portion 6 is a1, and the film thickness of the second blocking portion 7 is a2. It can satisfy:

[0129] Setting the minimum value of the ratio between a2 and a1 to 3 ensures that the second blocking part 7 has sufficient thickness to block more light. Setting the maximum value of the ratio between a2 and a1 to 50 prevents the second blocking part 7 from being too thick, which would result in a large module thickness of the display panel and thus avoid affecting the thin and light design of the display panel.

[0130] In one feasible implementation, to ensure that the second shielding part 7 has a large thickness, the film thickness of the second shielding part 7 can be set to be greater than 10 μm, so as to block more light at smaller angles.

[0131] Furthermore, referring to Figure 14, the display panel also includes a first dam 33, which is located around the second shield 7.

[0132] In this embodiment of the invention, the second shielding portion 7 can be formed using an inkjet printing process. In this pixel-level inkjet printing, a first dam 33 can be provided around the printing area to block the diffusion of ink at the edge of the printing area, ensuring that the ink of each pixel can be accurately deposited at a predetermined position, thereby guaranteeing the pixel-level accuracy of the printed image. In addition, the first dam 33 can also restrict and guide the flow of ink during the printing process, making the flow of ink in the printing area more stable and uniform, and avoiding the impact of uneven ink flow on printing consistency.

[0133] In one feasible implementation, as shown in FIG15, FIG15 is a schematic diagram of another structure of the display panel provided in the embodiment of the present invention. The first blocking part 6 and the second blocking part 7 in the blocking structure 4 are integrally formed, and the first blocking part 6 and the second blocking part 7 are connected to each other without any gap between them. Under this structure, the blocking structure 4 can be formed by using only one process to simultaneously form the first blocking part 6 and the second blocking part 7, which simplifies the process.

[0134] When the first blocking part 6 and the second blocking part 7 are integrally formed, in one feasible embodiment, the film thickness of the blocking structure 4 is greater than 10 μm to ensure that the blocking structure 4 has sufficient film thickness to block light over a wider angle range. Under the condition that the display panel achieves the same privacy angle, the spacing between adjacent first pixels 5 can be reduced, resulting in a larger aperture ratio for the first pixels 5.

[0135] In one possible implementation, referring again to FIG15, the display panel further includes a second dam 34, which is located on the side of the pixel layer 2 away from the substrate 1, and the orthographic projection of the second dam 34 is located around the orthographic projection of the shielding structure 4 on the plane where the substrate 1 is located.

[0136] In this embodiment of the invention, the shielding structure 4 can be formed using an inkjet printing process. In this pixel-level inkjet printing, a second dam 34 can be set around the printing area. The second dam 34 can effectively block the diffusion of ink at the edge of the printing area, ensuring that the ink of each pixel can be accurately deposited at a predetermined position, thereby guaranteeing the pixel-level accuracy of the printed image. In addition, the second dam 34 can also play a certain role in restricting and guiding the flow of ink during the printing process, making the flow of ink in the printing area more stable and uniform, and avoiding the impact of uneven ink flow on printing consistency.

[0137] Furthermore, referring again to Figure 15, the second dam 34 is located between the pixel layer 2 and the encapsulation layer 3, that is, the second dam 34 is formed before the encapsulation layer 3 is formed.

[0138] As mentioned above, the encapsulation layer 3 in this embodiment of the invention is a single-layer encapsulation and is very thin. Therefore, when the second dam 34 is located between the pixel layer 2 and the encapsulation layer 3, the encapsulation layer 3 will be uneven and the upper surface of the encapsulation layer 3 will be undulating. This kind of film layer undulation can still restrict the flow of ink and prevent it from spreading, thereby achieving more accurate pixel-level inkjet printing and making the position of the masking structure 4 more precise.

[0139] Furthermore, the upper surface of the encapsulation layer 3 away from the substrate 1 is a non-flat surface. That is, when the second dam 34 is located below the encapsulation layer 3, it will lift up the encapsulation layer 3, making the encapsulation layer 3 uneven. In the area between the second dam 34, the encapsulation layer 3 will be concave, thereby restricting the flow of ink.

[0140] Alternatively, as shown in Figure 16, which is another structural schematic diagram of the display panel provided in an embodiment of the present invention, the second dam 34 is located on the side of the encapsulation layer 3 away from the substrate 1, that is, the second dam 34 is formed after the encapsulation layer 3 is formed.

[0141] The second dam 34 is located above the encapsulation layer 3. During inkjet printing, the second dam 34 directly contacts the ink. The second dam 34 provides more significant obstruction to the ink flow, which can better guarantee the pixel-level accuracy of the printed image and reduce the risk of deviation in the formation position of the obstruction structure 4.

[0142] As shown in Figures 17 and 18, Figure 17 is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention, and Figure 18 is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The pixel layer 2 includes a pixel definition layer 50, which includes an opening for accommodating the light-emitting layer 26. In this embodiment of the present invention, some support pillars 51 may be provided above the pixel definition layer. The support pillars 51 are used to support the mask plate during the process of forming the light-emitting layer 26. In this embodiment of the present invention, the height of the second dam 34 may be greater than the height of the support pillars 51 so that the second dam 34 can effectively block the flow of ink.

[0143] In one feasible implementation, as shown in FIG19, FIG19 is a schematic diagram of another structure of the display panel provided in an embodiment of the present invention. The display panel further includes a light extraction layer 15 and a touch layer 14. Both the light extraction layer 15 and the touch layer 14 are located on the side of the first shielding portion 6 away from the substrate 1. Furthermore, the light extraction layer 15 is located between the first shielding portion 6 and the touch layer 14, thereby further separating the touch layer 14 from the pixel layer 2, thus minimizing signal interference between the touch layer 14 and the pixel layer 2 and ensuring touch performance.

[0144] Based on the same inventive concept, this embodiment of the invention also provides a method for manufacturing a display panel. Referring to Figure 3, and as shown in Figures 20 and 21, Figure 20 is a flowchart of one method for manufacturing a display panel provided by this embodiment, and Figure 21 is a flowchart of another method for manufacturing a display panel provided by this embodiment. This method includes:

[0145] Step S1: A pixel layer 2 is formed on one side of the substrate 1. The pixel layer 2 includes a first pixel 5.

[0146] Step S2: Form an encapsulation layer 3 on the pixel layer 2. The encapsulation layer 3 is a single-layer film structure.

[0147] Step S3: A shielding structure 4 is formed on the encapsulation layer 3. The shielding structure 4 includes a first shielding portion 6 and a second shielding portion 7. The first shielding portion 6 is located on the side of the encapsulation layer 3 away from the substrate 1. A first opening 8 is formed between the first shielding portions 6 of adjacent shielding structures 4. The second shielding portion 7 is located on the side of the first shielding portion 6 away from the substrate 1. A second opening 9 is formed between the second shielding portions 7 of adjacent shielding structures 4. In a direction perpendicular to the plane of the substrate 1, the first pixel 5, the first opening 8, and the second opening 9 at least partially overlap.

[0148] The display panel manufactured using the above method has a single-layer encapsulation design for its encapsulation layer 3.

[0149] The encapsulation structure in this encapsulation method consists of a very thin inorganic layer with a very small film thickness. Therefore, when the first blocking part 6 is placed on top of it, the vertical distance between the first blocking part 6 and the first pixel 5 can be greatly reduced, making the first blocking part 6 very close to the first pixel 5. The first blocking part 6 can block light emitted by the first pixel 5 at a larger angle. At the same time, a second blocking part 7 is also provided above the first blocking part 6. Compared with the first blocking part 6, the vertical distance between the second blocking part 7 and the first pixel 5 is slightly larger. The second blocking part 7 can block light emitted by the first pixel 5 at a smaller angle.

[0150] By adopting the technical solution provided in the embodiments of the present invention, under the condition that the display panel achieves the same privacy angle, the spacing between adjacent first pixels 5 can be reduced, so that the aperture ratio of the first pixel 5 can be increased, thereby effectively extending the lifespan of the first pixel 5.

[0151] In this embodiment of the invention, the encapsulation layer 3 can be formed using the ALD process. The single-layer encapsulation film formed by this process has high density and can effectively block the intrusion of external substances such as water vapor, oxygen, and impurities, thereby achieving a good encapsulation effect.

[0152] In one feasible implementation, referring to FIG8, FIG22 is a flowchart of another method for manufacturing a display panel provided in an embodiment of the present invention. After forming the first blocking portion 6, the manufacturing method further includes: forming a first film layer 13 on the first blocking portion 6, the first film layer 13 including a touch layer 14 and / or a light extraction layer 15. After forming the first film layer 13, a second blocking portion 7 is then formed.

[0153] In the light-shielding structure 4 formed by the above method, a first film layer 13 is spaced between the first blocking part 6 and the second blocking part 7. By designing parameters such as the number and thickness of the film layer 13, the longitudinal distance between the second blocking part 7 and the first pixel 5 can be flexibly adjusted, thereby adjusting the minimum light-shielding angle that the blocking structure 4 can have, and improving the flexibility of the privacy angle design for the display panel. Therefore, under the condition that the display panel achieves the same privacy angle, the spacing between adjacent first pixels 5 can be reduced, so that the aperture ratio of the first pixel 5 can be increased.

[0154] Furthermore, referring again to FIG22, after forming the first shielding portion 6 and before forming the first film layer 13, the fabrication method further includes: forming an organic spacer layer 22.

[0155] In the film structure of a display panel, the thickness of the organic layer is usually much greater than that of the inorganic layer. An organic spacer layer 22 is provided between the first film layer 13 and the first blocking portion 6. On one hand, the organic spacer layer 22, positioned between the touch layer 14 and the pixel layer 2, can reduce mutual interference between touch signals and display signals; and / or, the organic spacer layer 22, positioned between the light extraction layer 15 and the pixel layer 2, keeps the light extraction layer 15 and the pixel layer 2 far apart, allowing more oblique light emitted by the first pixel 5 and the second pixel 11 to enter the interface between the dimming portion 20 and the dimming layer 21, further improving the light extraction rate. On the other hand, the second blocking portion 7, being far apart from the first pixel 5, can block light emitted by the first pixel 5 at smaller angles, improving the privacy protection effect.

[0156] Furthermore, the process of forming the organic spacer layer 22 includes: forming the organic spacer layer 22 using an etching process so that the organic spacer layer 22 has a uniform film thickness and better film flatness.

[0157] For the etched organic spacer layer 22, referring to FIG9, the organic spacer layer 22 includes a first portion 23 located in the non-display area NAA and a second portion 24 located at least in the display area AA, wherein the film thickness of the first portion 23 is equal to the film thickness of the second portion 24.

[0158] Alternatively, the process of forming the organic spacer layer 22 may also include: forming the organic spacer layer 22 using a printing process so that the organic spacer layer 22 can have a larger film thickness, setting the film thickness of the organic spacer layer 22 within a wider range, thereby helping to adjust the longitudinal distance between the second blocking part 7 and the first pixel 5 more flexibly, and adjusting the light-blocking angle of the second blocking part 7.

[0159] For the organic spacer layer 22 formed by printing, during the inkjet printing process, the ink droplets in the central region can overlap and spread relatively uniformly, while in the edge region, the deposition distribution of the droplets changes, resulting in a smaller film thickness in the edge region. That is, referring to Figure 10, the organic spacer layer 22 includes a first portion 23 located in the non-display area NAA and a second portion 24 located at least in the display area AA, wherein the film thickness of the first portion 23 is smaller than the film thickness of the second portion 24. For example, the film thickness of the first portion 23 decreases along the direction from the display area AA to the non-display area NAA.

[0160] In one feasible implementation, as shown in FIG23, FIG23 is another flowchart of a method for manufacturing a display panel provided in an embodiment of the present invention, wherein the second shielding portion 7 is formed by a printing process. Before forming the second shielding portion 7, the manufacturing method further includes: forming a first dam 33, the first dam 33 being located around the printing area of ​​the second shielding portion 7.

[0161] In this embodiment of the invention, the second shielding portion 7 can be formed using an inkjet printing process. In this pixel-level inkjet printing, a first dam 33 can be provided around the printing area to block the diffusion of ink at the edge of the printing area, ensuring that the ink of each pixel can be accurately deposited at a predetermined position, thereby guaranteeing the pixel-level accuracy of the printed image. In addition, the first dam 33 can also restrict and guide the flow of ink during the printing process, making the flow of ink in the printing area more stable and uniform, and avoiding the impact of uneven ink flow on printing consistency.

[0162] In one feasible implementation, referring to FIG21, the process of forming the shielding structure 4 includes: forming an integrally molded first shielding part 6 and second shielding part 7 using a printing process.

[0163] The first shielding part 6 and the second shielding part 7 thus formed are connected to each other and there is no gap between them. The shielding structure 4 can be formed by using only one process to simultaneously form the first shielding part 6 and the second shielding part 7, which simplifies the process.

[0164] Furthermore, as shown in FIG24, FIG24 is another flowchart of the manufacturing method of the display panel provided in the embodiment of the present invention. After forming the pixel layer 2 and before forming the shielding structure 4, the manufacturing method further includes: forming a second dam 34, the second dam 34 being located around the printing area of ​​the shielding structure 4.

[0165] In this embodiment of the invention, the shielding structure 4 can be formed using an inkjet printing process. In this pixel-level inkjet printing, a second dam 34 can be set around the printing area. The second dam 34 can effectively block the diffusion of ink at the edge of the printing area, ensuring that the ink of each pixel can be accurately deposited at a predetermined position, thereby guaranteeing the pixel-level accuracy of the printed image. In addition, the second dam 34 can also play a certain role in restricting and guiding the flow of ink during the printing process, making the flow of ink in the printing area more stable and uniform, and avoiding the impact of uneven ink flow on printing consistency.

[0166] Based on the same inventive concept, this embodiment of the invention also provides a display device, as shown in FIG25. FIG25 is a schematic diagram of a structure of the display device provided in this embodiment of the invention, which includes the aforementioned display panel 100. Of course, the display device shown in FIG25 is merely illustrative, and the display device can be any electronic device with display function, such as a mobile phone, tablet computer, laptop computer, e-reader, or television.
