Description

Technical Field

[0001] This application relates to the field of display technology, and more particularly to a display panel and display device. Background Technology

[0002] Organic light-emitting diode (OLED) devices, as the core of the next generation of display and lighting technologies, have been widely used in smartphones, televisions, wearable devices and other fields due to their advantages such as self-illumination, high contrast, wide viewing angle, and ultra-thin flexibility.

[0003] Currently, some customers of OLED display panels have raised privacy concerns, meaning they want a clear and bright display when viewed from a direct angle, but for others to see the content from other angles. The mainstream solution is to use privacy screen protectors (passive privacy protection). However, privacy screen protectors themselves introduce numerous display problems, such as reduced brightness, changes in color and contrast, etc., affecting the user experience. Therefore, active privacy protection products that can switch between privacy and normal display modes at any time are more attractive to consumers.

[0004] Currently, active privacy products have added multiple light-blocking layers to control the viewing angle range. However, because the film layers on which the light-blocking layers are located may have large differences in different areas of the display panel, the distribution of the light-blocking layers has height differences. This results in inconsistent light-blocking effects of the light-blocking layers in different areas, leading to uneven luminous brightness in different areas. Summary of the Invention

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0030] Please refer to Figure 1 In the display panel provided by the related technology, the light-emitting side of the light-emitting pixel 1 is usually encapsulated by an encapsulation layer, including an organic encapsulation layer 2. Furthermore, in order to realize the privacy function of the display panel, at least one light-shielding layer 3 is usually provided above the organic encapsulation layer 2 to limit the light emission angle of the light-emitting pixel 1, thereby realizing the privacy function of the display panel. However, during the formation of the organic encapsulation layer 2, a film layer morphology with reduced thickness is formed at its edge, resulting in uneven thickness of the organic encapsulation layer 2. This causes a height difference between the light-shielding layer 3 at the middle and edge positions, resulting in inconsistent light-blocking effects of the light-shielding layer 3 at the middle and edge positions on the light-emitting pixel 2, causing uneven brightness during the display process of the display panel.

[0031] Please refer to Figure 2This application provides a display panel, which includes a display area and a non-display area 102 adjacent to the display area 101.

[0032] The display panel also includes a plurality of sub-pixels 10, an organic layer 21, and a first light-shielding layer 41; the plurality of sub-pixels 10 includes a first sub-pixel 11 and a second sub-pixel 12; the organic layer 21 is disposed on the light-emitting side of the plurality of sub-pixels 10, and the organic layer 21 includes a first organic portion 211 and a second organic portion 212. The first organic portion 211 is disposed within the display area 101, and the second organic portion 212 is connected to the first organic portion 211 within the display area 101 and extends into the non-display area 102, and the thickness of the second organic portion 212 is less than the thickness of the first organic portion 211; the first light-shielding layer 41 is disposed on the side of the organic layer 21 away from the plurality of sub-pixels 10, and the first light-shielding layer 41 includes a first light-shielding portion 411, and in a top view, the distance between the first light-shielding portion 411 and the first sub-pixel 11 is less than the distance between the first light-shielding portion 411 and the second sub-pixel 12.

[0033] The display panel also includes a spacer layer 30 disposed between the organic layer 21 and the first light-shielding layer 41. The spacer layer 30 is disposed in the non-display area 102 and extends into the display area 101 and partially overlaps with the second organic part 212 along the thickness direction of the display panel. In the display area 101, the spacer layer 30 partially overlaps with the first light-shielding part 411 along the thickness direction of the display panel.

[0034] In the implementation process, this application embodiment provides a spacer layer 30 that can extend into the display area 101 in the display panel. The spacer layer 30 is located between the second organic part 212 with a smaller thickness and the first light-shielding layer 41 to compensate for the step difference in the thinner part of the organic layer 21, reduce the step difference in the film layer position of the first light-shielding layer 41, improve the uniformity of the light blocking effect of the first light-shielding layer 41, and thus improve the uniformity of the light emission brightness of the display panel.

[0040] The thin-film transistor also includes a source and a drain disposed on the same layer. Both the source and drain are formed on the first interlayer insulating layer. The source is connected to the source region through a source contact hole, and the drain is connected to the drain region through a drain contact hole. The source and drain can be multiple layers or a single layer formed of low-resistance materials such as Al, Ti, Mo, Cu, Ni, or their alloys, or materials with high corrosion resistance.

[0046] Among them, multiple sub-pixels 10 are respectively set in multiple pixel openings, and each sub-pixel 10 is set in the corresponding pixel opening and located on the anode.

[0047] In some embodiments, the display panel further includes a cathode layer, which covers a plurality of sub-pixels 10 and a pixel definition layer; wherein, the anode provides holes to the sub-pixels 10, the cathode layer provides electrons to the sub-pixels 10, and the holes and electrons recombine in the sub-pixels 10 to excite light, thereby realizing the display function of the display panel.

[0048] Furthermore, the encapsulation layer 50 is disposed on the cathode layer, and the encapsulation layer 50 includes a first inorganic encapsulation layer 22, an organic layer 21, and a second inorganic encapsulation layer 23 stacked together; wherein, the first inorganic encapsulation layer 22 and the second inorganic encapsulation layer 23 can be prepared using inorganic materials, such as silicon nitride, silicon oxynitride, aluminum oxide, etc., which can play a role in blocking water and oxygen; while the organic layer 21 can be prepared using organic resin materials, such as acrylic resin, epoxy resin, etc., which can play a role in improving flatness and buffering stress.

[0049] In some embodiments, the display panel further includes a barrier 60 disposed in the non-display area 102, and the barrier 60 is used to block the overflow of the organic layer 21; wherein the first inorganic encapsulation layer 22 and the second inorganic encapsulation layer 23 both extend from the display area 101 to the non-display area 102 and cover the barrier 60, while the organic layer 21 is located on the side of the barrier 60 closer to the display area 101 and is blocked by the barrier 60.

[0052] The touch layer is disposed on the encapsulation layer 50, and the touch layer includes a touch metal layer and a touch insulating layer 53 covering and spacing the touch metal layer; wherein, the touch insulating layer 53 is located on the second inorganic encapsulation layer 23.

[0053] In some embodiments, the display panel further includes a first cover layer 54 disposed on the touch insulating layer 53, a second light-shielding layer 42 disposed on the side of the first cover layer 54 away from the touch insulating layer 53, at least one spacer layer 55 disposed on the side of the first cover layer 54 away from the touch insulating layer 53 and covering the second light-shielding layer 42, and a first light-shielding layer 41 disposed on the side of the at least one spacer layer 55 away from the second light-shielding layer 42.

[0054] In some embodiments, the materials of the first cover layer 54 and the spacer layer 55 may include organic materials, such as organic resin materials; the first cover layer 54 and the spacer layer 55 can improve the flatness of the film layer, adjust the spacing between the second light-shielding layer 42 and the sub-pixel 10, and adjust the spacing between the second light-shielding layer 42 and the first light-shielding layer 41.

[0055] In some embodiments, the first light-shielding layer 41 and the second light-shielding layer 42 can be a black matrix, and the materials of the first light-shielding layer 41 and the second light-shielding layer 42 can also be light-shielding materials. This application embodiment does not make specific limitations.

[0056] It is understood that the first light-shielding layer 41 in this application embodiment can be regarded as the outermost light-shielding layer in the display panel, that is, the light-shielding layer closest to the light-emitting surface. The display panel provided in this application embodiment can also provide more light-shielding layers between the first light-shielding layer 41 and the second light-shielding layer 42, such as at least one of the third light-shielding layer, the fourth light-shielding layer and the fifth light-shielding layer, and at least one spacer layer 55 is provided between adjacent light-shielding layers.

[0057] In some embodiments, such as Figure 2 As shown, at least one spacer layer 55 includes a first spacer layer 551, which is disposed on the side of the first cover layer 54 away from the touch insulating layer 53 and covers the second light-shielding layer 42. The first light-shielding layer 41 is disposed on the side of the first spacer layer 551 away from the second light-shielding layer 42.

[0058] Further, please refer to Figure 2 and Figure 3 The second light-shielding layer 42 includes a second light-shielding portion 422, and in the top view, the second light-shielding portion 422 is disposed adjacent to at least the first sub-pixel 11.

[0059] In some embodiments, in a top view, the second light-shielding portion 422 is disposed adjacent to both the first sub-pixel 11 and the second sub-pixel 12.

[0060] The second light-shielding layer 42 forms multiple second openings 420 above the multiple sub-pixels 10, that is, the second light-shielding layer 42 forms multiple second openings 420 on the light-emitting side of the multiple sub-pixels 10; furthermore, the display panel also includes multiple color resist blocks 421, and the multiple color resist blocks 421 are disposed in the multiple second openings 420, wherein the multiple second openings 420 can be configured in a one-to-one correspondence with the multiple sub-pixels 10, and the multiple color resist blocks 421 are also configured in a one-to-one correspondence with the multiple sub-pixels 10.

[0061] In this embodiment, the color of each color resist block 421 is the same as the light emission color of the corresponding sub-pixel 10. Thus, the multiple color resist blocks 421, together with the second light-shielding layer 42, can play a role in reducing reflection. Therefore, the display panel provided in this application embodiment does not need to be provided with a polarizer, which can reduce the thickness of the display panel and improve the transmittance of the display panel.

[0062] In some embodiments, the plurality of sub-pixels 10 may include a plurality of first sub-pixels 11 and a plurality of second sub-pixels 12, and a plurality of first openings 410 are formed in the first light-shielding layer 41. The plurality of first openings 410 may be configured to correspond to the plurality of second sub-pixels 12, for example, the plurality of first openings 410 may be configured to correspond one-to-one with the plurality of second sub-pixels 12.

[0063] Furthermore, the first opening 410 is located on the side of the second opening 420 that is away from the corresponding first sub-pixel 11.

[0064] It should be noted that the first light-shielding layer 41 includes a first light-shielding part 411, and in the top view, the distance between the first light-shielding part 411 and the first sub-pixel 11 is smaller than the distance between the first light-shielding part 411 and the second sub-pixel 12. Furthermore, the first light-shielding part 411 may surround or partially surround the first sub-pixel 11 to limit the light emission angle range of the first sub-pixel 11. In addition, the first light-shielding part 411 is not disposed on the light emission side of the second sub-pixel 12, that is, the first light-shielding part 411 does not effectively limit the light emission angle range of the second sub-pixel 12.

[0065] In some embodiments, the orthographic projection of the first light-shielding layer 41 onto the pixel definition layer 52 is disposed around the pixel opening where the first sub-pixel 11 is located, that is, disposed around the first sub-pixel 11, and the first opening 410 is surrounded by the first light-shielding portion 411; and the first light-shielding portion 411 is not disposed on the light-emitting side of the second sub-pixel 12. Therefore, the first light-shielding portion 411 can limit the light-emitting angle range of the first sub-pixel 11, so that the light-emitting angle range of the first sub-pixel 11 is smaller than the light-emitting angle range of the second sub-pixel 12, thereby enabling the first sub-pixel 11 to achieve privacy display of the display panel.

[0066] In some embodiments, when a polarizer is provided in the display panel, in a top view, the second light-shielding part 422 is disposed adjacent to the first sub-pixel 11, that is, the distance between the second light-shielding part 422 and the first sub-pixel 11 is smaller than the distance between the second light-shielding part 422 and the second sub-pixel 12; therefore, the first light-shielding part 411 and the second light-shielding part 422 are not provided on the light-emitting side of the second sub-pixel 12, and the orthographic projections of the first light-shielding part 411 and the second light-shielding part 422 on the pixel definition layer 52 both surround the first sub-pixel 12. In the pixel 11 configuration, a first light-shielding layer 41 forms a first opening 410 on the light-emitting side of the first sub-pixel 11, and a second light-shielding layer 42 forms a second opening 420 on the light-emitting side of the first sub-pixel 11, with the second opening 420 located between the first opening 410 and the first sub-pixel 11; wherein, the second light-shielding part 422 can block the large-angle light emission of the first sub-pixel 11, while the first light-shielding part 411 can block the small-angle light emission of the first sub-pixel 11, so as to achieve effective light blocking of the first sub-pixel 11.

[0067] In some embodiments, when the display panel is configured in a privacy mode, the first sub-pixel 11 emits light while the second sub-pixel 12 does not emit light; when the display panel is configured in a non-privacy mode, at least the second sub-pixel 12 emits light. That is, when the display panel is configured in a non-privacy mode, both the first sub-pixel 11 and the second sub-pixel 12 emit light, or the first sub-pixel 11 does not emit light while the second sub-pixel 12 emits light.

[0068] In some embodiments, the orthographic projection of the second opening 420 onto the pixel definition layer 52 covers the pixel opening in the pixel definition layer, that is, covers the corresponding sub-pixel 10; in addition, the edge of the first opening 410 and the edge of the second opening 420 may be flush along the thickness direction of the display panel, or the edge of the first opening 410 may expand outward relative to the edge of the second opening 420 in a direction away from the center of the first opening 410, or the edge of the first opening 410 may contract inward relative to the edge of the second opening 420 in a direction closer to the center of the first opening 410. The embodiments of this application are not specifically limited here.

[0069] In some embodiments, the display panel further includes a second cover layer 56 disposed on the spacer layer 55 and covering the first light-shielding layer 41, and the material of the second cover layer 56 can be an organic material, such as an organic resin material, which can improve the flatness of the film layer.

[0070] It should be noted that there is an organic layer 21 between the first light-shielding layer 41 and the sub-pixel 10, and between the second light-shielding layer 42 and the sub-pixel 10. During the formation process, the organic layer 21 will form a morphology with uneven film thickness. Specifically, the thickness of the organic layer 21 will gradually decrease at the edge, resulting in a large step difference between the organic layer 21 in the middle and the edge. At least there is also a step difference between the film layer of the first light-shielding layer 41 at the edge and the film layer of the first light-shielding layer 41 in the middle, resulting in an inconsistent height of the first light-shielding layer 41 in the middle and the edge. Consequently, the light-blocking effect on the sub-pixel 10 in the middle and the edge is also inconsistent, resulting in inconsistent luminous brightness of the display panel in the middle and the edge, which seriously affects the display effect of the display panel.

[0071] In this embodiment, the display panel further includes a spacer layer 30 disposed between the organic layer 21 and the first light-shielding layer 41. The spacer layer 30 is disposed in the non-display area 102 and extends into the display area 101 and is located on the side of the second organic part 212 away from the plurality of sub-pixels 10. The spacer layer 30 extends into the display area 101 and partially overlaps with the second organic part 212 along the thickness direction of the display panel. In the display area 101, the spacer layer 30 partially overlaps with the first light-shielding part 411 along the thickness direction of the display panel. By providing a spacer layer 30 that can extend into the display area 101 in the display panel, and the spacer layer 30 being located between the thinner second organic part 212 and the first light-shielding layer 41, this embodiment compensates for the step difference in the thinner position of the organic layer 21, reduces the step difference in the film layer position of the first light-shielding layer 41, improves the uniformity of the light blocking effect of the first light-shielding layer 41 on the emitted light, and thus improves the uniformity of the luminous brightness of the display panel.

[0072] It should be noted that the edge of the spacer layer 30 on the side away from the center of the display area 101 can be flush with the edge of the display panel, and the spacer layer 30 extends from the non-display area 102 toward the display area 101, covering the display area 101, and is located at least on the side of the second organic part 212 away from the sub-pixel 10; wherein, the spacer layer 30 is at least in the non-display area 102, and can be continuously covered, that is, the entire surface is provided.

[0073] The orthographic projection of the spacer layer 30 along the thickness direction of the display panel can cover the barrier wall 60 and the wiring area 510.

[0074] In some embodiments, the thickness of the spacer layer 30 is less than the thickness of the first organic part 211. It is understood that the spacer layer 30 can be made by a photomask process, which is more conducive to adjusting the coverage of the spacer layer 30 so as to achieve fine control of the coverage of the spacer layer 30. The organic layer 21 is made by an inkjet printing process, and its thickness is relatively larger.

[0075] Furthermore, there is at least one first height difference between the surface of the first light-shielding layer 41 opposite to the surface of the first organic part 211 and the surface of the first light-shielding layer 41 opposite to the surface of the second organic part 212 along the thickness direction of the display panel; there is at least one second height difference between the surface of the first organic part 211 away from the sub-pixel 10 and the surface of the second organic part 212 away from the sub-pixel 10 along the thickness direction of the display panel, and the average value of the first height difference is less than the average value of the second height difference; that is, after the spacer layer 30 is provided in this embodiment, the step difference generated by the first light-shielding layer 41 in the middle and edge regions of the display area 101 is less than the step difference generated by the organic layer 21 in the middle and edge regions of the display area 101, so as to effectively compensate for the step difference generated by the organic layer 21, improve the uniformity of the light blocking effect of the first light-shielding layer 41, and thus improve the uniformity of the light emission brightness of the display panel.

[0076] In other words, the display panel also includes a substrate, a plurality of sub-pixels 10 are disposed on the substrate, and an organic layer 21 is located on the side of the plurality of sub-pixels away from the substrate; wherein, the absolute value of the difference between the distance between the first light-shielding portion 411 located on the side of the first organic portion 211 away from the sub-pixel 10 and the substrate and the minimum distance between the first light-shielding portion 411 located on the side of the second organic portion 212 away from the sub-pixel 10 and the substrate has a first value; the absolute value of the difference between the distance between the surface of the first organic portion 211 on the side away from the substrate and the substrate and the minimum distance between the surface of the second organic portion 212 on the side away from the substrate and the substrate has a second value, and the first value is less than the second value.

[0077] The distance between the first light-shielding portion 411 located on the side of the first organic portion 211 away from the sub-pixel 10 and the substrate is greater than or equal to the maximum distance between the first light-shielding portion 411 located on the side of the second organic portion 212 away from the sub-pixel 10 and the substrate. In other words, the surface of the first light-shielding portion 411 on the side away from the second organic portion 212 does not extend beyond the surface of the first light-shielding portion 411 on the side away from the first organic portion 211 along the thickness direction of the display panel. This can prevent the spacer layer 30 from causing new step differences at the edge of the display area 101 due to the film layer where the first light-shielding layer 41 is located. It can also prevent the spacer layer 30 from overcompensating the step differences of the organic layer 21 in different areas, which would cause new height differences in the first light-shielding layer 41 in different areas, and thus cause uneven brightness in the display panel, such as dark lines.

[0078] In some embodiments, the surface of the second light-shielding portion 422 on the side away from the second organic portion 212 does not extend beyond the surface of the second light-shielding portion 422 on the side away from the first organic portion 211 along the thickness direction of the display panel; similarly, it can avoid the phenomenon of the spacer layer 30 overcompensating the step difference of the organic layer 21 in different areas, resulting in new height differences in different areas of the second light-shielding layer 42, which in turn leads to uneven brightness of the display panel, such as dark lines.

[0079] Furthermore, in this embodiment of the application, the edge of the spacer layer 30 can be specially designed so that the membrane layer above the spacer layer 30 can transition smoothly, thereby avoiding the appearance of protrusions and grooves in the membrane layer above the spacer layer 30.

[0080] In one specific embodiment of this application, please refer to Figure 2 and Figure 4 Multiple sub-pixels 10 can be divided into multiple pixel units 100, and each pixel unit 100 has at least two sub-pixels 10 with different emission colors; for example, each pixel unit 100 may include a first color sub-pixel 111, a second color sub-pixel 112 and a third color sub-pixel 113, and the emission colors of the first color sub-pixel 111, the second color sub-pixel 112 and the third color sub-pixel 113 are different from each other.

[0081] In some embodiments, the emission color of the first color sub-pixel 111 can be red, the emission color of the second color sub-pixel 112 can be green, and the emission color of the third color sub-pixel 113 can be blue.

[0082] In some embodiments, a plurality of sub-pixels 10 are arranged along a first direction X and a second direction Y, and the first direction X and the second direction Y intersect; correspondingly, a plurality of pixel units 100 are also arranged in an array along the first direction X and the second direction Y.

[0083] It should be noted that the multiple pixel units 100 can be divided into first pixel units and second pixel units. The sub-pixels in the first pixel unit are all first sub-pixels 11, and the sub-pixels in the second pixel unit are all second sub-pixels 12. Therefore, the first pixel unit can be mainly used to achieve privacy display, while the second pixel unit can be used for non-privacy display.

[0084] For example, in a plurality of pixel units 100 arranged along the first direction X, the first pixel unit and the second pixel unit are arranged alternately; in a plurality of pixel units 100 arranged along the second direction Y, the first pixel unit and the second pixel unit may also be arranged alternately.

[0085] In some embodiments, among a plurality of pixel units arranged along the second direction Y, a plurality of first color sub-pixels 111 and a plurality of second color sub-pixels 112 are arranged along the second direction Y to form a first column, a plurality of third color sub-pixels 113 are arranged along the second direction Y to form a second column, and the first column sub-pixels 10 and the second column sub-pixels 10 are arranged alternately along the first direction X.

[0086] In some embodiments, the first direction X and the second direction Y can be perpendicular to each other.

[0087] In this embodiment, such as Figure 4 As shown, in the top view, the boundary of the spacer layer 30 within the display area 101 is a straight line and is located between two adjacent columns of pixel units 100 along the first direction X; this is to avoid the boundary of the spacer layer 30 being located directly above the sub-pixel 10, and the boundary of the spacer layer 30 having a significant impact on the light emission of the sub-pixel 10 due to light refraction at the film interface.

[0088] In another embodiment of this application, please refer to Figure 2 and Figure 5 This implementation method and Figure 4 The difference in the embodiment shown is that the spacer layer 30 has a patterned structure 31 on the side near the center of the display area 101 to form at least one opening 310 on the side of the spacer layer 30 near the center of the display area 101.

[0089] In this embodiment, in the top view, the patterned structure 31 includes a concave-convex edge formed on the side of the spacer layer 30 near the center of the display area 101. Therefore, when the film layer above the spacer layer 30 is formed, for example, the first cover layer 54 and at least one spacer layer 55 are formed, the film layer can smoothly transition at the concave-convex edge of the spacer layer 30, avoiding height abrupt changes at the edge of the spacer layer 30 to form undesirable morphologies such as protrusions or grooves. This is more conducive to improving the flatness of the film layer above the spacer layer 30, for example, improving the flatness of the first cover layer 54 and at least one spacer layer 55. This can further improve the flatness of the film layer where the first light-shielding layer 41 is located, or improve the flatness of the film layer where the first light-shielding layer 41 and the second light-shielding layer 42 are located. At least the light-blocking effect of the first light-shielding layer 41 on the first sub-pixel 11 in different areas is improved, thus improving the brightness uniformity of the display panel.

[0090] Understandably, the concave-convex edge has a recess formed by inward indentation toward the side away from the center of the display area 101, and this recess can be regarded as an opening 310.

[0091] In this embodiment, in the top view, the uneven structure formed by the edge of the spacer layer 30 within the display area 101 can be regarded as a part of the edge of the spacer layer 30 protruding towards the center of the display area 101 to form an uneven structure; and the shape of the protrusion in the top view can be a rectangle, a triangle, an arc, or other polygons, etc.

[0092] In another specific embodiment of this application, please refer to Figure 6 and Figure 7 The spacer layer 30 has a patterned structure 31 on the side near the center of the display area 101 to form at least one opening 310 on the side of the spacer layer 30 near the center of the display area 101.

[0093] Similarly, during the formation of the film layer above the spacer layer 30, such as during the formation of the first cover layer 54 and at least one spacer layer 55, the film layer can smoothly transition at the patterned structure 31 of the spacer layer 30, avoiding height abrupt changes at the edge of the spacer layer 30 to form undesirable morphologies such as protrusions or grooves. This is more conducive to improving the flatness of the film layer above the spacer layer 30, such as improving the flatness of the first cover layer 54 and at least one spacer layer 55. This can further improve the flatness of the film layer where the first light-shielding layer 41 is located, or improve the flatness of the film layer where the first light-shielding layer 41 and the second light-shielding layer 42 are located. At least the light-blocking effect of the first light-shielding layer 41 on the first sub-pixel 11 in different areas is improved, thus improving the brightness uniformity of the display panel.

[0094] In this embodiment, the spacer layer 30 includes a body 32 that extends from the non-display area 102 into the display area 101, while the patterned structure 31 is located on the side of the body 32 near the center of the display area 101; the patterned structure 31 may be spaced apart from the body 32 to form an opening 310.

[0095] In some embodiments, the patterned structure 31 includes at least one strip-shaped sub-part, which does not overlap with the sub-pixel 10 along the thickness direction of the display panel. In this embodiment, the strip-shaped sub-part is formed by patterning the portion of the spacer layer 30 near the center of the display area 101. This reduces the probability of a protrusion when the film layer above the spacer layer 30 covers the location of the spacer layer 30, thereby providing a buffer space for the film layer above the spacer layer 30 during its formation, allowing for a smooth transition during the formation of the film layer above the spacer layer 30. Furthermore, the strip-shaped sub-part does not overlap with the sub-pixel 10, so as to avoid the boundary of the spacer layer 30 being located directly above the sub-pixel 10. The boundary of the spacer layer 30 would have a significant impact on the light emission of the sub-pixel 10 due to light refraction at the film layer interface.

[0096] The patterned structure 31 may include a plurality of first strip-shaped sub-parts 311 formed at the edge of the spacer layer 30 and spaced apart, and the plurality of first strip-shaped sub-parts 311 are arranged along the second direction Y, with adjacent first strip-shaped sub-parts 311 spaced apart, thereby providing a buffer space for the film layer above the spacer layer 30 during the formation process, so that the film layer above the spacer layer 30 can undergo a smooth transition during the formation process.

[0097] In some embodiments, in a top view, the boundary of the body 32 within the display area 101 is a straight line and is located between two adjacent columns of pixel units 100 along the first direction X, and the first strip-shaped sub-part 311 is also located between the first column of sub-pixels 10 and the second column of sub-pixels 10; in order to avoid the boundary of the spacer layer 30 being located directly above the sub-pixels 10, and the boundary of the spacer layer 30 having a significant impact on the light emission of the sub-pixels 10 due to light refraction at the film interface.

[0098] In some embodiments, the patterned structure 31 and the second organic portion 212 at least partially overlap along the thickness direction of the display panel, and the patterned structure 31 and the first organic portion 211 do not overlap along the thickness direction of the display panel; that is, the patterned structure 31 may be located on the side of the second organic portion 212 away from the sub-pixel 10, rather than on the side of the first organic portion 211 away from the sub-pixel 10, so as to avoid the film layer above the first organic portion 211 from protruding due to the arrangement of the patterned structure 31.

[0099] In another embodiment of this application, please refer to Figure 8 This implementation method is the same as Figure 7 The difference in the embodiment shown is that the patterned structure 31 includes at least one second strip-shaped sub-part 312 disposed on the side of the body 32 near the center of the display area 101, and the second strip-shaped sub-part 312 extends along the second direction Y. The second strip-shaped sub-part 312 is spaced apart from the body 32 to form an opening 310.

[0100] Similarly, during the formation of the film layer above the spacer layer 30, such as during the formation of the first cover layer 54 and at least one spacer layer 55, the film layer can smoothly transition at the patterned structure 31 of the spacer layer 30, avoiding height abrupt changes at the edge of the spacer layer 30 to form undesirable morphologies such as protrusions or grooves. This is more conducive to improving the flatness of the film layer above the spacer layer 30, such as improving the flatness of the first cover layer 54 and at least one spacer layer 55. This can further improve the flatness of the film layer where the first light-shielding layer 41 is located, or improve the flatness of the film layer where the first light-shielding layer 41 and the second light-shielding layer 42 are located. At least the light-blocking effect of the first light-shielding layer 41 on the first sub-pixel 11 in different areas is improved, thus improving the brightness uniformity of the display panel.

[0101] In some embodiments, in a top view, the boundary of the body 32 within the display area 101 is a straight line and is located between two adjacent columns of pixel units 100 along the first direction X, and the second strip-shaped sub-part 312 is also located between the first column of sub-pixels 10 and the second column of sub-pixels 10; in order to avoid the boundary of the spacer layer 30 being located directly above the sub-pixels 10, and the boundary of the spacer layer 30 having a significant impact on the light emission of the sub-pixels 10 due to light refraction at the film interface.

[0102] In another embodiment of this application, please refer to Figure 9 This implementation method is the same as Figure 8 The difference in the illustrated embodiment is that the patterned structure 31 includes at least one second strip-shaped sub-part 312 disposed on the side of the body 32 near the center of the display area 101 and at least one connecting sub-part 313 connecting the second strip-shaped sub-part 312 and the body 32, and the second strip-shaped sub-part 312 extends along the second direction Y, and the connecting sub-part 313 extends along the first direction X and connects the second strip-shaped sub-part 312 and the body 32; and the second strip-shaped sub-part 312, the body 32 and the connecting sub-part 313 surround or partially surround each other to form an opening 310.

[0103] Similarly, during the formation of the film layer above the spacer layer 30, such as during the formation of the first cover layer 54 and at least one spacer layer 55, the film layer can smoothly transition at the patterned structure 31 of the spacer layer 30, avoiding height abrupt changes at the edge of the spacer layer 30 to form undesirable morphologies such as protrusions or grooves. This is more conducive to improving the flatness of the film layer above the spacer layer 30, such as improving the flatness of the first cover layer 54 and at least one spacer layer 55. This can further improve the flatness of the film layer where the first light-shielding layer 41 is located, or improve the flatness of the film layer where the first light-shielding layer 41 and the second light-shielding layer 42 are located. At least the light-blocking effect of the first light-shielding layer 41 on the first sub-pixel 11 in different areas is improved, thus improving the brightness uniformity of the display panel.

[0104] In some embodiments, in a top view, the boundary of the body 32 within the display area 101 is a straight line and is located between two adjacent columns of pixel units 100 along the first direction X. The second strip-shaped sub-part 312 is also located between the first column of sub-pixels 10 and the second column of sub-pixels 10, and the connecting sub-part 313 is located between adjacent sub-pixels 10 along the second direction Y. This is to avoid the boundary of the spacer layer 30 being located directly above the sub-pixels 10, and the boundary of the spacer layer 30 having a significant impact on the light emission of the sub-pixels 10 due to light refraction at the film interface.

[0105] In another specific embodiment of this application, please refer to Figure 10In this embodiment, within the display area 101, the thickness of the first cover layer 54 on the side of the second organic part 212 away from the sub-pixel 10 is greater on the side closer to the center of the display area 10 than on the side away from the center of the display area 101; furthermore, within the display area 101, the thickness of the first cover layer 54 on the side of the second organic part 212 away from the sub-pixel 10 gradually decreases along the direction away from the center of the display area 101.

[0106] It is understood that, since a spacer layer 30 is added to the side of the second organic part 212 away from the sub-pixel 10 in this embodiment, the spacer layer 30 will elevate the side of the second organic part 212 away from the sub-pixel 10. To avoid the spacer layer 30 being too abrupt at the edge of the film layer, causing bulges or grooves in the film layer above it, this embodiment sets a gradient in the thickness of the first cover layer 54 located on the side of the second organic part 212 away from the sub-pixel 10, so that the film layer above the spacer layer 30, for example, at least one spacer layer 55, during the formation process, During the process, the film layer can smoothly transition above the second organic part 212, avoiding height abrupt changes at the edge of the spacer layer 30 to form undesirable morphologies such as protrusions or grooves. This is more conducive to improving the flatness of the film layer above the spacer layer 30, such as improving the flatness of at least one spacer layer 55. This can further improve the flatness of the film layer where the first light-shielding layer 41 is located, or improve the flatness of the film layer where the first light-shielding layer 41 and the second light-shielding layer 42 are located. At least the light-blocking effect of the first light-shielding layer 41 on the first sub-pixel 11 in different areas is improved, thus improving the brightness uniformity of the display panel.

[0107] It should be noted that in other embodiments of this application, at least one of the at least one spacer layer 55 can also be set with a thickness gradient in the same way. For example, in the display area 101, the thickness of the spacer layer 55 on the side of the second organic part 212 away from the sub-pixel 10 gradually decreases in the direction away from the center of the display area 101, which can also make the film layer above the second organic part 212 have a smooth transition during the formation process.

[0108] In some embodiments, the thickness of at least a portion of the spacer layer 30 located within the display area 101 is smaller on the side closer to the center of the display area 101 than on the side farther from the center of the display area 101; further, the thickness of at least a portion of the spacer layer 30 located within the display area 101 gradually decreases along the direction closer to the center of the display area 101; similarly, in this embodiment, the thickness of the spacer layer 30 located on the side of the second organic portion 212 farther from the sub-pixel 10 is set in a gradient, so that during the formation of the film layer above the spacer layer 30, such as the first cover layer 54 and / or at least one spacer layer 55, during the formation process, The film layer can smoothly transition above the second organic part 212, avoiding height abrupt changes at the edge of the spacer layer 30 to form undesirable morphologies such as protrusions or grooves. This is more conducive to improving the flatness of the film layer above the spacer layer 30, such as improving the flatness of the first cover layer 54 and / or at least one spacer layer 55. This can further improve the flatness of the film layer where the first light-shielding layer 41 is located, or improve the flatness of the film layer where the first light-shielding layer 41 and the second light-shielding layer 42 are located. At least the light-blocking effect of the first light-shielding layer 41 on the first sub-pixel 11 in different areas is improved, thus improving the brightness uniformity of the display panel.

[0109] It should be noted that in the above embodiments, the thickness of at least one of the first covering layer 54, the spacer layer 55 and the spacer layer 30 is designed to be gradient above the second organic part 212, which can be achieved by photomask, for example by using a semi-transparent mask to differentiate the thickness of the above film layers at different positions.

[0110] In other embodiments of this application, such as Figure 2 As shown, the thickness of the spacer layer 30 located in the display area 101 is greater on the side closer to the center of the display area 101 than on the side farther from the center of the display area 101; furthermore, it gradually decreases in the direction away from the center of the display area 101; since the spacer layer 30 is an organic material, during the formation process, due to the leveling property of the organic material, the thickness of the spacer layer 30 gradually decreases in the direction away from the center of the display area 101, and the thickness of the spacer layer 30 begins to increase again near the baffle wall 60.

[0111] Furthermore, in this embodiment, the spacer layer 30 is located between the organic layer 21 and the first light-shielding layer 41; further still, the spacer layer 30 is disposed between the organic layer 21 and the first cover layer 54, or the spacer layer 30 is disposed between the first cover layer 54 and the first light-shielding layer 41; and the specific location of the spacer layer 30 will be described in detail below.

[0112] In one specific embodiment of this application, please refer to Figure 2The spacer layer 30 is disposed on the side of the touch insulating layer 53 away from the second inorganic encapsulation layer 23. Furthermore, the spacer layer 30 is disposed between the touch insulating layer 53 and the first cover layer 54.

[0113] Therefore, in this embodiment, by placing the spacer layer 30 on the touch insulating layer 53, the step difference formed on the upper surface of the touch insulating layer 53 can be compensated. After the first cover layer 54 is formed on the touch insulating layer 53 and the spacer layer 30, the step difference generated by the surface of the first cover layer 54 away from the touch insulating layer 53 at the center and edge of the display area 101 is smaller than the step difference generated by the surface of the organic layer 21 away from the sub-pixel 10 at the center and edge of the display area 101. In other words, the spacer layer 30 can compensate for the step difference generated by the organic layer 21 in different areas, so that the second light-shielding layer 42 is on a flatter film layer.

[0114] Similarly, the step difference between the surface of the first spacer layer 551 on the side away from the first cover layer 54 at the center and edge of the display area 101 is relative to... Figure 1 As shown in the structure, it can be effectively reduced, so that the first light-shielding layer 41 is also on a flatter film layer, which can help improve the light-blocking uniformity of the first light-shielding part 411 to the first sub-pixel 11 in different areas and improve the brightness uniformity of the display panel.

[0115] More preferably, the surface of the spacer layer 30 away from the multiple sub-pixels 10 does not extend beyond the surface of the first organic part 211 away from the multiple sub-pixels 10 along the thickness direction of the display panel; in order to avoid the spacer layer 30 overcompensating the step difference of the organic layer 21 in different areas, causing the first light-shielding layer 41 to have new height differences in different areas, which in turn causes the display panel to have uneven brightness, such as dark lines.

[0116] In another embodiment of this application, please refer to Figure 6 The spacer layer 30 is disposed on the side of the first cover layer 54 away from the touch insulation layer 53. Furthermore, the spacer layer 30 is disposed between the first cover layer 54 and the first spacer layer 551, and covers the second light-shielding layer 42.

[0117] Therefore, in this embodiment, by placing the spacer layer 30 on the first cover layer 54, the step difference formed on the upper surface of the first cover layer 54 can be compensated. After the first spacer layer 551 is formed on the first cover layer 54 and the spacer layer 30, the step difference generated by the surface of the first spacer layer 551 away from the first cover layer 54 at the center and edge of the display area 101 is smaller than the step difference generated by the surface of the organic layer 21 away from the sub-pixel 10 at the center and edge of the display area 101. In other words, the spacer layer 30 can compensate for the step difference generated by the organic layer 21 in different areas, making the surface of the first spacer layer 551 flatter, and making the first light-shielding layer 41 also on a flatter film layer. This can help improve the light-blocking uniformity of the first light-shielding part 411 on the first sub-pixel 11 in different areas and improve the brightness uniformity of the display panel.

[0118] In another embodiment of this application, please refer to Figure 11 At least one spacer layer 55 includes a first spacer layer 551 and a second spacer layer 552, wherein the first spacer layer 551 is located between the second light-shielding layer 42 and the second spacer layer 552, and the second spacer layer 552 is located between the first spacer layer 551 and the first light-shielding layer 41.

[0119] In this embodiment, the spacer layer 30 is disposed on the side of the first spacer layer 551 away from the first cover layer 54. Furthermore, the spacer layer 30 is disposed between the first spacer layer 551 and the second spacer layer 552.

[0120] It should be noted that, since the spacer layer 55 is made of organic material, the thickness of a single spacer layer 55 is limited due to process constraints. Therefore, when it is necessary to make the distance between the second light-shielding layer 42 and the first light-shielding layer 41 larger, at least two spacer layers 55 can be provided between the second light-shielding layer 42 and the first light-shielding layer 41, namely the first spacer layer 551 and the second spacer layer 552. In addition, if the material of the first spacer layer 551 and the material of the second spacer layer 552 are the same, then there will be no obvious dividing line between the first spacer layer 551 and the second spacer layer 552.

[0121] Therefore, in this embodiment, by placing the spacer layer 30 on the first spacer layer 551, the step difference formed on the upper surface of the first spacer layer 551 can be compensated. When the second spacer layer 552 is formed on the first spacer layer 551 and the spacer layer 30, the step difference generated at the center and edge of the display area 101 by the surface of the second spacer layer 552 away from the first spacer layer 551 is less than the step difference generated at the center and edge of the display area 101 by the surface of the organic layer 21 away from the sub-pixel 10. In other words, the spacer layer 30 can compensate for the step differences generated by the organic layer 21 in different areas, making the surface of the second spacer layer 552 flatter, and reducing the step difference generated at the center and edge of the display area 101 by the surface of the second spacer layer 552 away from the first spacer layer 551. Figure 1 As shown in the structure, it can also be effectively reduced, so that the first light-shielding layer 41 is also on a flatter film layer, which can help improve the light-blocking uniformity of the first light-shielding part 411 to the first sub-pixel 11 in different areas and improve the brightness uniformity of the display panel.

[0122] In summary, this embodiment of the application provides a spacer layer 30 that can extend into the display area 101 in the display panel, and the spacer layer 30 is located between the thinner second organic part 212 and the first light-shielding layer 41. This compensates for the step difference in the thinner part of the organic layer 21, reduces the step difference in the film layer position of the first light-shielding layer 41, improves the uniformity of the light blocking effect of the first light-shielding layer 41, and thus improves the uniformity of the light emission brightness of the display panel.
