[0034] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0036] Figure 1 FIG. 1 is a schematic plan view of a display panel provided by an embodiment of the present disclosure. Figure 2 Shown Figure 1 An AA cross-sectional view of the display panel. It should be noted that: Figure 1 The rectangular display panel 100 is used as an example for illustration, and the actual shape of the display panel is not limited. In some other embodiments of the present disclosure, the display panel may also be a circle, a rounded rectangle, or any other feasible shape. Optionally, the display panel provided in this embodiment may be a display panel using inorganic light-emitting diode display technology, such as a Micro LED display panel, or a Mini LED display panel, etc. This type of display panel has the advantages of high brightness, low power consumption, and easy splicing, and is widely used in display products. Optionally, Figure 2 Take the display panel including the substrate 00, the driving layer 01 arranged on one side of the substrate 00 and the light emitting element LD as an example for explanation, the light emitting element LD is electrically connected to the driving layer 01, and obtains the driving signal required for light emission through the driving layer 01, and optionally, the driving layer 01 is provided with a driving circuit, and the driving circuit can select the circuit in the prior art, which is not specifically limited in the present disclosure. It should be noted that, Figure 2 The film layer structure included in the middle driving layer 01 is only for illustration and does not represent the actual number and size of film layers. The light emitting element LD is, for example, a Micro LED or a Mini LED.

[0037] Please refer to Figure 1 and Figure 2 The present disclosure provides a display panel 100, including a first area Q1 and a second area Q2, wherein the display panel further includes a light shielding layer 10, and a thickness h1 of the light shielding layer 10 located in the first area Q1 is different from a thickness h2 of the light shielding layer 10 located in the second area Q2.

[0038] The first area Q1 and the second area Q2 mentioned in the present disclosure refer to two different areas in the display panel, for example, the display panel is provided with different areas such as the pixel area 31, the redundant pixel area 32, and the wiring area 33. Taking the Micro LED display panel as an example, the light-emitting element LD is usually transferred to one side of the driving layer 01 by mass transfer and electrically connected to the driving layer 01. At this time, the area provided with the light-emitting element LD can be regarded as the pixel area 31 of the display panel. When a bad pixel appears on the display panel, for example, when a certain light-emitting element LD in the pixel area 31 does not emit light, it is necessary to repair the area where the non-luminous light-emitting element LD is located. At this time, a redundant pixel area 32 is usually set in the display panel, and a redundant light-emitting element is introduced in the redundant pixel area 32 to replace the non-luminous light-emitting element LD. In order to drive the light-emitting element LD to emit light, the driving layer 01 of the display panel is provided with a pixel driving circuit corresponding to the light-emitting element LD. In order to provide a signal to the pixel driving circuit, a wiring area 33 is set in the display panel, and the signal is transmitted to the pixel driving circuit through the wiring of the wiring area 33, thereby driving the light-emitting element LD to emit light. For the pixel area 31 and the redundant pixel area 32, the driving layer 01 has a metal part that is electrically connected to the light-emitting element LD, and for the wiring area 33, a metal wiring is provided. If the aforementioned metal parts and metal wirings in the display panel are not blocked by the light-shielding layer 10, the ambient light will cause reflection when irradiating the aforementioned metal parts and metal wirings, greatly reducing the contrast of the display panel and affecting the viewing effect of the user. To this end, the present disclosure can introduce a light-shielding layer 10 in the above-mentioned area where the metal parts and metal wirings are provided, and use the light-shielding layer 10 to cover the metal parts and metal wirings, thereby avoiding or reducing the reflection problem caused by the metal structure and improving the contrast of the display panel.

[0039] The first area Q1 mentioned in this embodiment may be any one of the pixel area 31, the redundant pixel area 32, and the wiring area 33 mentioned above, and the second area Q2 may also be any one of the pixel area 31, the redundant pixel area 32, and the wiring area 33 mentioned above. For the first area Q1 and the second area Q2, there may be differences in the structure itself, such as whether a light-emitting element is provided, whether a pixel driving circuit is provided, the color of the light-emitting element, etc. Based on the possible structural differences between the first area Q1 and the second area Q2, the present disclosure sets the thickness of the light-shielding layer 10 located in the first area Q1 and the thickness of the light-shielding layer 10 located in the second area Q2 to be different, while reducing the reflectivity of the first area Q1 and the second area Q2, it is also beneficial to balance the difference in anti-reflection effect between the first area Q1 and the second area Q2, improve the consistency of the overall anti-reflection effect, and then help improve the consistency of the overall contrast of the display product, improve the display effect, and help improve the viewing experience of the user.

[0040] Please continue to refer to Figure 1 and Figure 2 This embodiment takes the display panel as a transparent display panel as an example to further illustrate the present disclosure. The transparent display panel technology sets a light-transmitting layer 02 in the display area of ​​the display panel, so that the light behind the display panel can penetrate the display panel and be perceived by the human eye in front of the display panel, thereby achieving a transparent display effect. No pixel driving circuit and wiring are set in the light-transmitting area corresponding to the light-transmitting layer 02, so as to meet the light transmission requirements of this area.

[0041] Please refer to Figure 1 and Figure 2 In an optional embodiment of the present disclosure, the display panel further includes a light-transmitting layer 02, the light-transmitting layer 02 includes an opening K, the opening K includes a first opening K1 and a second opening K2, a light-shielding layer 10 is disposed in the first opening K1 and the second opening K2, and the thickness of the light-shielding layer 10 in the first opening K1 and the second opening K2 is different. Optionally, the first opening K1 is located in the aforementioned first zone Q1, and the second opening K2 is located in the aforementioned second zone Q2. It should be noted that, Figure 1 The relative positional relationship among the light-transmitting layer 02 , the first region Q1 , the second region Q2 and the light-shielding layer 10 is only for illustration, and the present disclosure is not limited thereto. The arrangement of the first region Q1 and the second region Q2 is also only for illustration.

[0042] In the process of manufacturing the transparent display panel, after forming the driving circuit, wiring and light-emitting element on one side of the substrate 00, the film layer in the area where the driving circuit, light-emitting element LD and wiring are not set in the display panel will be removed (for example, only the substrate 00 is retained), and a light-transmitting layer 02 will be formed in the corresponding area to improve the transparency of the transparent display panel. After the light-transmitting layer 02 is formed, the original pixel area 31, the redundant pixel area 32 and the wiring area 33 will be confined in the opening formed by the light-transmitting layer 02, wherein the light-transmitting layer 02 forms an opening which can be understood as a cross section perpendicular to the plane where the light-emitting surface of the display panel is located (for example, Figure 2 The morphology presented in the cross section) is that the local shading layer 10 is clamped by the light-transmitting layer 02 on both sides, or in this cross section, it can be presented as a light-shielding layer 10 is provided in the missing or hollowed-out area between the light-transmitting layers 02. Therefore, although the present application has a light-shielding layer 10 located in the opening of the light-transmitting layer 02, it does not mean that the light-shielding layers 10 in different areas are separated or isolated by the light-transmitting layer 02. It also does not mean that the overall area of ​​the light-transmitting layer 02 is larger than the overall area of ​​the light-shielding layer 10. In some embodiments, the size of the opening K can also be understood as the size presented or visible in the above cross section. It should be noted that, Figure 1 and Figure 2 The opening shown is a non-enclosed opening, and the light-transmitting layer 02 is located on both sides of the opening K along the first direction D1, but the present disclosure is not limited thereto, and the relative position of the opening K and the light-transmitting layer 02 can also be embodied in other ways, for example, please refer to Figure 3 , Figure 3 The figure shows a partial top view of the display panel provided by the embodiment of the present disclosure. In the embodiment, the light-transmitting layer 02 is located on both sides of the first region Q1 along the first direction D1 and on both sides along the second direction D2. This situation increases the area of ​​the light-transmitting layer 02 in the display panel, which is beneficial to improving the overall transmittance of the display panel.

[0043] Please continue to refer to Figure 2 When the light shielding layer 10 is subsequently formed, the light shielding layer 10 will be filled in the opening corresponding to the light-transmitting layer 02. In this embodiment, the first opening K1 corresponding to the light-transmitting layer 02 may be located in the first area Q1, and the first area Q1 may be, for example, any one of the pixel area 31, the redundant pixel area 32, and the wiring area 33. The second opening K2 may be located in the second area Q2, and the second area Q2 may be, for example, any one of the pixel area 31, the redundant pixel area 32, and the wiring area 33. Figure 1 The embodiment shown is described by taking the first area Q1 as the pixel area 31 and the second area Q2 as the redundant pixel area 32 as an example. Figure 1 In the description, the redundant pixel area 32 is taken as an example in which no light emitting element LD is provided, but the present disclosure is not limited to this. When the light emitting element LD in the pixel area 31 does not emit light, a light emitting element LD can be provided in the corresponding redundant pixel area 32 to replace the original light emitting element LD that does not emit light. The present disclosure is conducive to avoiding or reducing the metal reflection phenomenon in the first opening K1 and the second opening K2 by providing a light shielding layer 10 in the first opening K1 and the second opening K2. In addition, in the present embodiment, the thickness of the light shielding layer 10 in the first opening K1 is different from the thickness of the light shielding layer 10 in the second opening K2, which is conducive to balancing the difference in reflection effect that may be caused by the structural difference in the first opening K1 and the second opening K2, and improving the consistency of the overall anti-reflection effect, which is conducive to improving the consistency of the overall contrast of the display panel, improving the display effect and the viewing experience of the user.

[0044] Please continue to refer to Figure 2 In an optional embodiment of the present disclosure, at least a portion of the top surface of the light shielding layer 10 does not exceed the opening K where it is located. For example, when the light-transmitting layer 02 includes Figure 2 When the first opening K1 and the second opening K2 are shown, the light-shielding layer 10 located in the first opening K1 does not exceed the first opening K1, and the light-shielding layer 10 located in the second opening K2 does not exceed the second opening K2. That is to say, the orthographic projection of the light-shielding layer 10 on the plane where the substrate 00 is located is located within the orthographic projection range of the corresponding opening K on the plane where the substrate 00 is located, and the light-shielding layer 10 does not overlap with other areas of the light-transmitting layer 02 except the area where the opening K is located. In this way, the light-shielding layer 10 will not block the light-transmitting area of ​​the light-transmitting layer 02, which is beneficial to ensure the light-transmitting area of ​​the display panel and improve the transparency of the display panel.

[0045] Please continue to refer to Figure 2 In an optional embodiment of the present disclosure, among the plurality of first regions Q1, the thickness h1 of the light shielding layer 10 of at least some of the first regions Q1 is smaller than the thickness h2 of the light shielding layer 10 of the second region Q2. At this time, optionally, the first region Q1 is provided with a light emitting element LD, and the second region Q2 is a redundant pixel region 32 or a wiring region 33 where no light emitting element LD is provided.

[0046] In this embodiment, the first region Q1 is provided with a light emitting element LD, and the first region Q1 may be, for example, the pixel region 31 mentioned in the above embodiment, and the corresponding light emitting element LD is a light emitting element of the pixel region 31 transferred to the driving layer 01 side by means of mass transfer. In addition, the first region Q1 may also be a redundant pixel region 32 provided with a light emitting element LD, and the corresponding light emitting element LD is a light emitting element transferred to the redundant pixel region 32 to compensate for the defect of the light emitting element LD that does not emit light in the pixel region 31. For the first region Q1 in which the light-emitting element LD is provided, before being electrically connected to the light-emitting element LD, the driving layer 01 exposes the metal structure that needs to be electrically connected to the light-emitting element LD. After the light-emitting element LD is transferred to the first region Q1, the electrode 22 of the light-emitting element LD is electrically connected to the aforementioned metal structure. When the light-shielding layer 10 is introduced into the first region Q1, the light-shielding layer 10 is used to shield the aforementioned electrode 22 and the metal structure. Since the light-emitting chip 21 of the light-emitting element LD itself can partially shield the electrode 22 and the metal structure, the thickness of the light-shielding layer 10 introduced in the first region Q1 can be set to be smaller, which is smaller than the thickness of the light-shielding layer 10 in the second region Q2. The second area Q2 is not provided with the light emitting element LD. When the second area Q2 is the redundant pixel area 32, the metal structure originally used for electrical connection with the light emitting element LD will be exposed in the second area Q2. When the second area Q2 is the wiring area 33, the metal wiring will be exposed in the second area Q2. Therefore, the metal structure or metal wiring in the second area Q2 is completely shielded by the light shielding layer 10. Therefore, the thickness of the light shielding layer 10 in the second area Q2 can be set to be larger, so that it is greater than the thickness of the light shielding layer 10 in the first area Q1. This is conducive to balancing the shielding effect of the first area Q1 provided with the light emitting element LD and the second area Q2 not provided with the light emitting element LD by the light shielding layer 10, thereby balancing the difference in anti-reflection effect between the first area Q1 and the second area Q2, which is conducive to improving the consistency of the overall anti-reflection effect of the display panel, and then it is conducive to improving the consistency of the overall contrast of the display panel and improving the display effect.

[0047] Please continue to refer to Figure 2In an optional embodiment of the present disclosure, the display panel further includes a light-transmitting layer 02, the light-transmitting layer 02 includes an opening K, the opening K includes a first opening K1 and a second opening K2, the first opening K1 is located in the first area Q1, the second opening K2 is located in the second area Q2, and the projection areas of the first opening K1 and the second opening K2 are the same. In this embodiment, the first area Q1 is provided with a light-emitting element LD, for example, it can be a pixel area 31, and it can also be a redundant pixel area 32 provided with a light-emitting element LD. In this embodiment, the projection areas of the first opening K1 and the second opening K2 are the same, and the light-emitting element LD is not provided in the second area Q2. At this time, the second area Q2 can be regarded as a redundant pixel area 32 without a light-emitting element LD. In the manufacturing process of the display panel, when the light-emitting element LD is not considered, the redundant pixel area 32 and the pixel area 31 have the same structure, for example, the size and shape of the corresponding openings are the same, and the volume of the openings is the same. It should be noted that the same mentioned in this embodiment refers to the same within the allowable error range. In this embodiment, the redundant pixel region 32 and the pixel region 31 are configured to have the same structure, so that the redundant pixel region 32 can be used to reliably repair the light-emitting element LD that does not emit light in the pixel region 31 .

[0048] When the first area Q1 is a pixel area 31 or a redundant pixel area 32 provided with a light emitting element LD, and the second area Q2 is a redundant pixel area 32 not provided with a light emitting element LD, without considering the difference in thickness of the light shielding layer 10 between the first area Q1 and the second area Q2, the difference between the first area Q1 and the second area Q2 is only whether the light emitting element LD is provided, and the volumes of the openings corresponding to the two are the same. In the embodiment of the present disclosure, the thickness of the light shielding layer 10 located in the first area Q1 is set to be less than the thickness of the light shielding layer 10 located in the second area Q2. At this time, optionally, the difference between the thickness h2 of the light shielding layer 10 located in the second area Q2 and the thickness h1 of the light shielding layer 10 located in the first area Q1 is:

[0049] Δh=(H*C*ω) / C–(H*CV)*ω) / (CS), wherein V represents the volume of the light-emitting chip 21 in the light-emitting element LD, S represents the volume of the electrode 22 in the light-emitting element LD, H represents the thickness of the light-transmitting layer 02, C represents the volume of the opening, and ω represents the solid content of the light-shielding layer 10.

[0050] In this embodiment, the thickness difference between the light shielding layer 10 located in the first area Q1 and the light shielding layer 10 located in the second area Q2 refers to the height difference between the top surface of the light shielding layer 10 located in the first area Q1 and the top surface of the light shielding layer 10 located in the second area Q2. The top surface of the light shielding layer 10 mentioned in this embodiment refers to the plane where the highest point of the light shielding layer 10 in the corresponding opening is located. In the manufacturing process of the display panel, after the manufacturing of the light-transmitting layer 02 is completed, the pixel area 31, the redundant pixel area 32, and the wiring area 33 are located in the opening. When manufacturing the light shielding layer 10, the light shielding layer 10 will first cover the entire surface of the transparent layer away from the substrate 00. At this time, the light shielding layer 10 will also be filled into each opening. Finally, the light shielding layer in the transparent area can be removed by photolithography or the like. In the process of removing the light shielding layer 10 in the transparent area, the light shielding layer 10 in the opening will also be affected by the photolithography process, causing the height of the light shielding layer 10 to decrease. When the first region Q1 is the pixel region 31 or the redundant pixel region 32 provided with the light emitting element LD, and the second region Q2 is the redundant pixel region 32 not provided with the light emitting element LD, along the first direction D1, the first opening K1 corresponding to the first region Q1 and the second opening K2 corresponding to the second region Q2 have the same width, and along the first direction D1, the width of the light shielding layer 10 accommodated in the first opening K1 will be equal to the width of the light shielding layer 10 that can be accommodated in the second opening K2. Since the light emitting element LD is provided in the first opening K1 and the light emitting element is not provided in the second opening K2, after the unnecessary light shielding layer 10 is removed by processes such as photolithography, the thickness of the light shielding layer 10 retained in the first opening K1 will be less than the thickness of the light shielding layer 10 retained in the second opening K2, and only one process of removing the light shielding layer 10 is required to achieve that the thickness of the light shielding layer 10 in the first opening K1 is less than the thickness of the light shielding layer 10 in the second opening K2, which not only balances the anti-reflection effects of the first region Q1 and the second region Q2, but also helps to simplify the manufacturing process of the display panel. It should be noted that, in the present embodiment, the first opening K1 corresponding to the first area Q1 and the second opening K2 corresponding to the second area Q2 have the same width along the first direction D1, which means that along a cross section perpendicular to the plane where the display panel is located and parallel to the first direction D1 (for example Figure 2 In other words, what is compared are the sizes of the first opening K1 and the second opening K2 in the above cross-section. It should also be noted that, in the embodiments of the present disclosure, the comparison of the width or thickness of the shading layer 10 is also a comparison of the sizes of the shading layer 10 in the above cross-section.

[0051] Please continue to refer to Figure 1 and Figure 2When the first region Q1 is a pixel region 31 or a redundant pixel region 32 provided with a light-emitting element LD, and the second region Q2 is a redundant pixel region 32 without a light-emitting element LD, a feasible implementation method of the present disclosure is that the thickness of the light-shielding layer 10 located in the first region Q1 is less than the thickness of the light-shielding layer 10 located in the second region Q2. At this time, optionally, the difference between the thickness h2 of the light-shielding layer 10 located in the second region Q2 and the thickness h1 of the light-shielding layer 10 located in the first region Q1 is: Δh=V*ω / C, wherein V represents the volume of the light-emitting element LD chip, ω represents the solid content of the light-shielding layer 10, and C represents the volume of the opening.

[0052] When the volume S of the electrode 22 of the light emitting chip 21 is small and much smaller than the opening volume C, Δh=(H*C*ω) / C–(H*CV)*ω) / (CS) can be simplified to: Δh=(H*C*ω) / C–(H*CV)*ω) / C, and further simplified to Δh=V*ω / C. That is to say, the difference between the thickness of the light shielding layer 10 of the first region Q1 and the thickness of the light shielding layer 10 of the second region Q2 is related to the volume V of the light emitting chip 21 in the light emitting element LD, the solid content ω of the light shielding layer 10, and the volume C of the opening. The first region Q1 is provided with a light emitting element LD, and the light emitting element LD can partially shield the metal structure of the region, and then further shield with the light shielding layer 10 whose thickness is less than the thickness of the light shielding layer 10 of the second region Q2 by V*ω / C, which is conducive to making the light shielding effect of the first region Q1 and the light shielding effect of the second region Q2 close to each other, and the anti-reflection effect close to each other, so as to improve the overall display effect of the display panel.

[0053] Figure 4 Shown Figure 1 Another AA cross-section of the display panel, please refer to Figure 4 In an optional embodiment of the present disclosure, in the first region Q1 , the light shielding layer 10 exposes at least a portion of the side wall of the light emitting element LD.

[0054] Specifically, this embodiment shows a solution in which part of the side wall of at least one light-emitting element LD in the display panel is shielded by the light-shielding layer 10 and part of the side wall is not shielded by the light-shielding layer 10, that is, the light-shielding layer 10 exposes at least part of the side wall of the light-emitting element LD, so that the light emitted by the light-emitting element LD can be emitted from at least part of the side wall exposed by the light-shielding layer 10 in addition to the front of the light-emitting element LD, which is beneficial to increase the overall light output of the light-emitting element LD, thereby helping to improve the light-emitting brightness of the light-emitting element LD. It should be noted that the light-emitting element LD includes a light-emitting chip 21 and an electrode 22 located on one side of the light-emitting chip 21. The side wall of the light-emitting element LD mentioned in this embodiment refers to the side wall of the light-emitting chip 21 in the light-emitting element LD that can emit light.

[0055] Please continue to refer to 1 and Figure 2 In an optional embodiment of the present disclosure, among the plurality of light emitting elements LD, the sidewalls of some of the light emitting elements LD are not covered with the light shielding layer 10. It should be noted that the sidewalls of the light emitting element LD in this embodiment refer to the sidewalls of the light emitting chip 21 in the light emitting element LD.

[0056] Specifically, this embodiment shows a solution in which the side wall of at least one light-emitting element LD in the display panel is not covered with the light-shielding layer 10, that is, the side wall of the light-emitting element LD is exposed outside the light-shielding layer 10 as a whole. When the light-emitting element LD emits light, the light can be emitted from the side wall of the light-emitting element LD, thereby increasing the amount of light of the light-emitting element LD at a large viewing angle, which is beneficial to improving the overall brightness of the light-emitting element LD. For the light-emitting element LD with low luminous efficiency in the display panel, the side wall of the light-emitting element LD can be exposed outside the light-shielding layer 10 in the above manner to improve the luminous brightness of the light-emitting element LD with low luminous efficiency in the display panel and balance the luminous brightness difference of the light-emitting elements LD with different luminous efficiencies in the display panel. It should be noted that which side walls of the light-emitting elements LD in the display panel are exposed outside the light-shielding layer 10 can be set according to actual needs, and the present disclosure does not limit this.

[0057] Please refer to Figure 4 In an optional embodiment of the present disclosure, among the multiple light emitting elements LD, the side walls of some of the light emitting elements LD are covered with a light shielding layer 10.

[0058] In this embodiment, when the side wall of the light emitting element LD is blocked by the light shielding layer 10, the light output of the light emitting element LD at a large viewing angle will be reduced. By setting the light shielding layer 10 on at least part of the side wall of the light emitting element LD, the light output of the light emitting element LD at a large viewing angle can be adjusted, so as to adjust the brightness of the corresponding light emitting element LD at a large viewing angle and adjust the overall brightness of the light emitting element LD. In practical applications, which side walls of the light emitting element LD are blocked by the light shielding layer 10 and the thickness of the light shielding layer 10 set on the side wall of the light emitting element LD can be selected according to actual needs, and the present disclosure is not limited. Figure 4 The embodiment shown is described by taking the case where part of the side wall of at least one light emitting element LD is blocked by the light shielding layer 10 and part of the side wall is not blocked by the light shielding layer 10 as an example. In some other embodiments of the present disclosure, in at least one light emitting element LD, the blocking amount of the side wall by the light shielding layer 10 (i.e., the thickness of the light shielding layer 10) can be adjusted according to actual needs. For example, please refer to Figure 5 , Figure 5 Shown Figure 1 Another AA cross-sectional view of the display panel, compared to Figure 4 , Figure 5The illustrated embodiment increases the shielding amount of the light shielding layer 10 on the side wall of the light emitting chip 21 in the light emitting element LD, and further reduces the lateral light output of the light emitting element LD.

[0059] It should be noted that Figure 2 , Figure 4 and Figure 5 In the embodiment, only the relative positional relationship between one light-emitting element LD and the light-shielding layer 10 in the display panel is shown. In the first case, the light-shielding layer 10 does not cover the side wall of the light-emitting chip 21 in the light-emitting element LD. In the second case, the light-shielding layer 10 covers the side wall of the light-emitting chip 21 in the light-emitting element LD with a smaller area (corresponding to a smaller thickness of the light-shielding layer). In the third case, the light-shielding layer 10 covers the side wall of the light-emitting chip 21 in the light-emitting element LD with a larger area (corresponding to a larger thickness of the light-shielding layer). When a plurality of light-emitting elements LD are provided in the display panel, the positional relationship between different light-emitting elements LD and the light-shielding layer 10 can be embodied in any one of the above three cases, or a combination of any two, or all three cases, and the present disclosure does not specifically limit this.

[0060] Please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 When the first region Q1 is a pixel region 31 or a redundant pixel region 32 provided with a light-emitting element LD, and the second region Q2 is a redundant pixel region 32 not provided with a light-emitting element LD, in an optional embodiment of the present disclosure, a plane where the top surface of the light-shielding layer 10 in the redundant pixel region 32 is located is lower than a plane where the top surface of the light-emitting element LD in the first region Q1 is located.

[0061] In the present embodiment, the first region Q1 is provided with a light-emitting element LD, the second region Q2 is not provided with a light-emitting element LD and the second region Q2 is a redundant pixel region 32. At this time, the thickness of the light-shielding layer 10 located in the second region Q2 is greater than the thickness of the light-shielding layer 10 located in the first region Q1. At the same time, the top surface of the light-shielding layer 10 located in the second region Q2 is lower than the top surface of the light-emitting element LD located in the first region Q1. This helps to avoid the light-shielding layer 10 in the second region Q2 from blocking the light emitted by the light-emitting element LD, thereby ensuring the light brightness of the light-emitting element LD. In addition, when the top surface of the light-shielding layer 10 located in the second zone Q2 is set to be lower than the top surface of the light-emitting element LD located in the first zone Q1, the metal structure is simultaneously shielded by the light-shielding layer 10 and the light-emitting chip 21 of the light-emitting element LD in the first zone Q1, and the metal structure is shielded by the light-shielding layer 10 in the second zone Q2 whose top surface does not exceed the top surface of the light-emitting element LD in the first zone Q1, which is beneficial to make the light-shielding effect of the light-shielding layer 10 in the redundant pixel area 32 closer to the light-shielding effect of the first zone Q1 where the light-emitting element LD is arranged, so it is beneficial to improve the consistency of the light-shielding effect of each area of ​​the display panel and improve the overall display effect of the display panel.

[0062] Figure 6 Shown Figure 3 A BB cross-section of the display panel, please refer to Figure 6 , and combined with Figure 2 , Figure 4 and Figure 5 In an optional embodiment of the present disclosure, the display panel provided by the present disclosure further includes a third zone Q3; the thickness h1 of the light-shielding layer 10 located in the first zone Q1 is less than the thickness h2 of the light-shielding layer 10 located in the second zone Q2, and less than the thickness h3 of the light-shielding layer 10 located in the third zone Q3, and the thickness h3 of the light-shielding layer 10 located in the third zone Q3 is less than or equal to the thickness h2 of the light-shielding layer 10 located in the second zone Q2. The light-transmitting layer 02 includes a third opening K3, and the third opening K3 is located in the third zone Q3. It should be noted that the thickness of the light-shielding layer 10 mentioned in this embodiment refers to the thickness of the light-shielding layer 10 in a cross section along a plane perpendicular to the light-emitting surface of the display panel (for example Figure 2 , Figure 4 , Figure 5 and Figure 6 The comparison of the thickness of the shading layer 10 in different areas is actually a comparison of the thickness of the shading layer 10 in different areas in the above cross section.

[0063] In this embodiment, when the display panel includes the third zone Q3, optionally, the third zone Q3 has a different shape structure from the first zone Q1 and the second zone Q2. The orthographic projections of the first zone Q1 and the second zone Q2 on the light emitting surface of the display panel may be, for example, a square structure, and the orthographic projection of the third zone Q3 on the light emitting surface of the display panel may be a long strip structure. At this time, the thicknesses of the light shading layer 10 in the third zone Q3 and other zones may be set differently. For example, the thickness of the light shading layer 10 in the third zone Q3 may be set to be less than or equal to the thickness of the light shading layer 10 in the second zone Q2, so that the light shading effect of the third zone Q3 is more consistent with the light shading effect of the first zone Q1, which is beneficial to balancing the overall light shading effect of the first zone Q1, the second zone Q2 and the third zone Q3, and is beneficial to improving the contrast consistency of different regions, and further beneficial to improving the overall display effect of the display panel. Optionally, in this embodiment, the first region Q1 is provided with a light emitting element LD, specifically a pixel region 31 or a redundant pixel region 32 provided with a light emitting element LD, the second region Q2 is a redundant pixel region 32 not provided with a light emitting element LD, and the third region Q3 is a wiring region 33. The wiring region 33 is provided with wiring for providing signals to pixel circuits in the pixel region 31 and the redundant pixel region 32, for example, a signal line for providing a scan signal, a data line for providing a data signal, a reset line for providing a reset signal, a power line for providing a power signal, etc. In this embodiment, the metal structure in the first region Q1 is shielded by the light emitting element LD and the light shielding layer 10, and the metal structure in the second region Q2 is shielded by the light shielding layer 10, so that the thickness of the light shielding layer 10 in the first region Q1 can be set to be less than the thickness of the light shielding layer 10 in the second region Q2, so as to achieve a balance between the light shielding effects in the first region Q1 and the second region Q2. The third area Q3, for example, is a long strip structure with wiring, and neither the third area Q3 nor the second area Q2 is provided with a light-emitting element LD. When the thickness of the shading layer 10 of the third area Q3 is set to be less than or equal to the thickness of the shading layer 10 of the second area Q2, it is beneficial to improve the consistency of the shading effect in the third area Q3 and the second area Q2, and further improve the consistency of the overall shading effect of the third area Q3, the second area Q2 and the first area Q1, so as to improve the contrast consistency of different areas of the display panel and improve the overall display effect.

[0064] The above embodiment shows that the top surface of the light shielding layer 10 in the opening K is a planar solution. In actual products, the top surface of the light shielding layer 10 may also be embodied in other forms. For example, please refer to Figure 7 , Figure 7 Shown Figure 1Another AA-direction cross-sectional view of the display panel, which differs from the aforementioned embodiment in that the top surface morphology of the light-shielding layer 10 in the opening is different. When the first region Q1 is a pixel region 31 or a redundant pixel region 32 provided with a light-emitting element LD, and the second region Q2 is a redundant pixel region 32 not provided with a light-emitting element LD, the first opening K1 is located in the first region Q1, and the second opening K2 is located in the second region Q2. Optionally, the top surface morphology of the light-shielding layer 10 in the first opening K1 is different from the top surface morphology of the light-shielding layer 10 in the second opening K2. It should be noted that the top surface morphology of the light-shielding layer 10 mentioned in this embodiment refers to the cross-section of the light-shielding layer 10 along a plane perpendicular to the light-emitting surface of the display panel (for example Figure 7 The comparison of the top surface morphology of the shading layer 10 in different areas actually compares the top surface morphology of the shading layer 10 in different areas in the above cross section.

[0065] In the present embodiment, when a light-emitting element LD is provided in the first region Q1, the light-emitting element LD is located in the middle region corresponding to the first opening K1 or in a position close to the middle region, and when a light-shielding layer 10 is formed in the first opening K1, the light-shielding layer 10 will at least fill in between the lateral direction of the light-emitting element LD and the side wall of the first opening K1. No light-emitting element LD is provided in the second region Q2, and when a light-shielding layer 10 is formed in the second opening K2, the light-shielding layer 10 will fill in the interval defined by the side wall corresponding to the second opening K2. Since there is a difference between the first opening K1 and the second opening K2 as to whether a light-emitting element LD is provided, when the light-shielding layer 10 is introduced into the first opening K1 and the second opening K2 respectively, the top surfaces of the light-shielding layer 10 in the first opening K1 and the second opening K2 will have different morphologies, for example, the cross-sectional structures of the light-shielding layer 10 in the first opening K1 and the second opening K2 are different, so as to prevent the light-shielding layer 10 from being distorted. Figure 7 For example, the cross section is, for example, a direction perpendicular to the plane where the display panel is located. Figure 1The cross section is taken at the position of the AA section line shown, in which the shape of the light shielding layer 10 in the first opening K1 is different from the morphology of the light shielding layer 10 in the second opening K2. Optionally, part of the top surface of the light shielding layer 10 includes a curved surface. This embodiment is described by taking the cross-sectional structure of the light shielding layer 10 in the first opening K1 as two curved surfaces on the top surface, and the cross-sectional structure of the light shielding layer 10 in the second opening K2 as one curved surface on the top surface as an example. When the top surface of the light shielding layer 10 in the first opening K1 and the second opening K2 is set as a curved surface, the light shielding layer 10 in the first opening K1 and the light shielding layer 10 in the second opening K2 have a more consistent reflection effect on light, which is beneficial to improving the consistency of the contrast of different areas in the display panel, and is beneficial to improving the overall display effect of the display panel. In addition, when the top surface of the light-shielding layer 10 in the first opening K1 and the second opening K2 is a curved structure, the light-shielding layer 10 in the first opening K1 and the second opening K2 can be manufactured in the same process, and there is no need to introduce different manufacturing processes for the light-shielding layer 10 in the first opening K1 and the second opening K2 respectively. This is beneficial to simplify the manufacturing process of the display panel and improve the manufacturing efficiency.

[0066] Please continue to refer to Figure 7 In an optional embodiment of the present disclosure, a light-emitting element LD is disposed in the first opening K1. In the first opening K1, a portion of the top surface of the light-shielding layer 10 forms a first curved surface m1. In the second opening K2, the top surface of the light-shielding layer 10 forms a second curved surface m2. The curvature of the first curved surface m1 is different from that of the second curved surface m2.

[0067] Due to the climbing effect of the light shielding layer 10 during the manufacturing process, when the light shielding layer 10 is formed in the first opening K1, the light shielding layer 10 extends onto the side surface of the light emitting element LD and the side wall of the first opening K1 to form a first curved surface m1 which is low in the middle and high on both sides. Figure 7In the cross-sectional view shown, the top surface of the light shielding layer 10 in the first opening K1 is embodied as two first curved surfaces m1, and the two first curved surfaces m1 are respectively located on both sides of the light emitting element LD. Since no light emitting element LD is disposed in the second opening K2, the light shielding layer 10 will slope along the sidewall of the second opening K2, forming a second curved surface m2 that is low in the middle and high on both sides. The first opening K1 is located in the first area Q1, and the first area Q1 is a pixel area 31 or a redundant pixel area 32 provided with a light-emitting element LD. The second opening K2 is located in the second area Q2, and the second area Q2 is a redundant pixel area 32 without a light-emitting element LD. At this time, the shapes and sizes of the first opening K1 and the second opening K2 are consistent or nearly consistent. Since the light-emitting element LD is provided in the first opening K1 and the light-emitting element LD is not provided in the second opening K2, the curvature of the first curved surface m1 formed in the first opening K1 and located between the light-emitting element LD and the side wall of the first opening K1 is different from the curvature of the second curved surface m2 formed between the side walls in the second opening K2. In this way, the structural design of the first opening K1 provided with the light-emitting element LD and the second opening K2 without the light-emitting element LD can be better matched, and the shading requirements at the positions of the first opening K1 and the second opening K2 can be met. Moreover, the first curved surface in the first opening K1 and the second curved surface m2 in the second opening K2 can be formed in the same manufacturing process without introducing an additional manufacturing process, which is conducive to simplifying the overall manufacturing process of the display panel and improving production efficiency.

[0068] Please continue to refer to Figure 1 and Figure 7In an optional embodiment of the present disclosure, the curvature of the first curved surface m1 corresponding to the light shielding layer 10 in the first opening K1 is smaller than the curvature of the second curved surface m2 corresponding to the light shielding layer 10 in the second opening K2. When the first opening K1 is located in the first area Q1 and the second opening K2 is located in the second area Q2, the first area Q1 is the pixel area 31 or the redundant pixel area 32 provided with the light emitting element LD, and the second area Q2 is the redundant pixel area 32 not provided with the light emitting element LD, the light shielding layer 10 in the first opening K1 climbs on the side of the light emitting element LD and the side wall of the first opening K1, forming a first curved surface m1 with high sides and low center, the first curved surface m1 is formed between the light emitting element LD and the side wall of the first opening K1, the size between the side of the light emitting element LD and the side wall of the first opening K1 is smaller than the width of the first opening K1, and thus the curvature of the first curved surface m1 formed is smaller. In the second opening K2, the light shielding layer 10 climbs up the side wall of the second opening K2 to form a second curved surface m2 with high sides and low center. The width of the second opening K2 is greater than the distance between the side of the light emitting element LD in the first opening K1 and the side wall of the first opening K1, so the curvature of the second curved surface m2 is greater than the curvature of the first curved surface m1. Therefore, the setting mode that the curvature of the first curved surface m1 in the first opening K1 is smaller than the curvature of the second curved surface m2 in the second opening K2 better matches the actual structural features in the first opening K1 and the second opening K2, and can meet the light shielding requirements of the light shielding layer 10 for the metal structures in the first opening K1 and the second opening K2. In addition, the mode that the top surfaces of the first light shielding layer 10 and the second light shielding layer 10 are both curved surfaces is also conducive to balancing the light shielding effect of the light shielding layer 10 in the first opening K1 and the second opening K2, and improving the consistency of the contrast of different areas.

[0069] Figure 8 Shown Figure 7 A relative position relationship diagram of the light emitting element LD in the first opening K1 at the lowest point of the first curved surface m1 and the second curved surface m2. It should be noted that, in order to more clearly reflect the structure of the lowest point of the first curved surface m1 and the second curved surface m2, Figure 8 In addition to illustrating the light shielding layer 10 in the first opening K1 and the second opening K2, the top view structure of the lowest point in the first opening K1 and the second opening K2 is also illustrated. Figure 8 The connection line of the lowest point of the first arc surface m1 is two independent straight lines, and the connection line of the lowest point of the second arc surface m2 is also a straight line for illustration, but the present disclosure is not limited to this. Figure 8 In an optional embodiment of the present disclosure, the orthographic projection of the lowest point P1 of the first curved surface m1 on the light-emitting surface of the display panel at least partially surrounds the light-emitting element LD; the orthographic projection of the lowest point P2 of the second curved surface m2 on the light-emitting surface of the display panel is a line.

[0070] In this embodiment, the lowest point of the first arc surface m1 can be regarded as a combination of the lowest points of multiple U-shaped arcs obtained by intercepting the display panel with a plane passing through the center line of the first opening K1 and perpendicular to the light-emitting surface of the display panel as a cross section (there are countless such cross sections). This embodiment is described by taking the line connecting the multiple lowest points of a single first arc surface m1 as a straight line as an example, but is not limited to this. Two first arc surfaces m1 are formed in the first opening K1, and the lowest points of the two first arc surfaces m1 respectively form two straight lines located on both sides of the light-emitting element LD, which is equivalent to the lowest points of the two first arc surfaces m1 being arranged in a manner of partially surrounding the light-emitting element LD in the first opening K1, and not focusing on the area where the light-emitting element LD is located. This arrangement is more conducive to the emission of light from the light-emitting element LD and prevents crosstalk between different light-emitting elements LD. In the second opening K2, the lowest point of the second arc surface m2 can be regarded as a combination of the lowest points of multiple U-shaped arcs obtained by intercepting the display panel with a plane passing through the center line of the second opening K2 and perpendicular to the light-emitting surface of the display panel as a cross section (there are countless such cross sections). In this embodiment, the lowest points of the multiple U-shaped arcs corresponding to the second arc surface m2 are converged into a straight line for illustration, and the top surface of the second arc surface m2 as a whole forms a U-shaped concave structure with a low middle and high sides. The lowest point of the second arc surface m2 in the second opening K2 is located in the middle area of ​​the second opening K2 or close to the center area, while the lowest points of the two first arc surfaces m1 in the first opening K1 are both located on both sides of the middle area of ​​the first opening K1.

[0071] Thus, in this embodiment, the first curved surface m1 formed in the first opening K1 and the lowest point of the first curved surface m1 are both located between the side of the light-emitting element LD and the side wall of the first opening K1, and the second curved surface m2 formed in the second opening K2 and the lowest point of the second curved surface m2 are located in the central area or close to the central area of ​​the second opening K2, which is equivalent to forming a concave structure in the two side areas of the light-emitting element LD in the first zone Q1 and the second zone Q2 where the light-emitting element LD is not set, and the concave structure is used to absorb ambient light in the area around the light-emitting element LD and other areas, which is beneficial to improve the consistency of the shading effect of the first zone Q1 and the second zone Q2, thereby helping to improve the consistency of the contrast of different areas in the display panel and the overall display effect. It should be noted that Figure 8 The illustrated embodiment is described by taking the light-transmitting layer 02 located on both sides of the first area Q1 and the second area Q2 as an example. The first opening K1 and the second opening K2 are openings having two oppositely disposed side walls, and are not closed openings.

[0072] It should also be noted that, in the above embodiment, the first area Q1 is a pixel area 31 or a redundant pixel area 32 provided with a light emitting element LD, the second area Q2 is a redundant pixel area 32 not provided with a light emitting element LD, and the thickness of the light shielding layer 10 in the first area Q1 is less than the thickness of the light shielding layer 10 in the second area Q2. However, the present disclosure is not limited to this. In some other embodiments of the present disclosure, the first area and the second area may also be embodied in other situations. For example, please refer to Fig. 9 and Fig.10 , Fig. 9 FIG. 1 is another schematic plan view of a display panel provided by an embodiment of the present disclosure. Fig.10 Shown Fig. 9 A CC cross-sectional view of a display panel, the display panel includes a plurality of first regions Q11 and a plurality of second regions Q12, optionally, the first region Q11 and the second region Q12 are both provided with light-emitting elements LD, in this case, the first region Q11 can be a pixel region 31 or a redundant pixel region 32 provided with a light-emitting element LD, and the second region Q11 can also be embodied as a pixel region 31 or a redundant pixel region 32 provided with a light-emitting element LD, and this embodiment is described by taking the first region Q11 and the second region Q12 as an example of a pixel region 31 provided with a light-emitting element LD, the first region Q11 includes a first opening K11, and the second region Q12 includes a second opening K12. In this embodiment, the thickness of the light-shielding layer 10 in the first region Q11 and the second region Q12 provided with the light-emitting element LD is designed differently, which is conducive to balancing the difference in the light-emitting brightness of different light-emitting elements LD.

[0073] Please continue to refer to Fig. 9 and Fig.10 In an optional embodiment of the present disclosure, among the multiple first regions Q11, the thickness of the light shielding layer 10 of at least some of the first regions Q11 is greater than the thickness of the light shielding layer 10 of the second region Q12. Optionally, the light emitting colors of the light emitting elements LD arranged in the first region Q11 and the second region Q12 are different. For example, the light emitting efficiency of the light emitting element LD arranged in the first region Q11 is higher than the light emitting efficiency of the light emitting element LD arranged in the second region Q12. At this time, when the thickness of the light shading layer 10 of the first region Q11 is set to the thickness of the light shading layer 10 of the second region Q12, for example, the light shading layer 10 of the first region Q11 can be set to cover at least part of the side wall of the light emitting element LD in the first region Q11, and the light shading layer 10 of the second region Q12 can be set not to cover the side wall of the light emitting element LD in the second region Q12. This is beneficial to reduce the lateral light output of the light emitting element LD with higher light emitting efficiency in the first region Q11, so as to reduce the overall light output of the corresponding light emitting element LD, thereby balancing the large viewing angle light emitting brightness difference between the light emitting element LD with higher light emitting efficiency in the first region Q11 and the light emitting element LD with lower light emitting efficiency in the second region Q12, and further beneficial to improving the uniformity of the light emitting brightness of the first region Q11 and the second region Q12.

[0074] Fig.10 In the illustrated embodiment, only a portion of the sidewalls of the light-emitting element LD in the first region Q11 are covered by the light-shielding layer 10, and the sidewalls of the light-emitting element LD in the second region Q12 are not covered by the light-shielding layer 10. However, the present disclosure is not limited thereto. In some other embodiments of the present disclosure, when the thickness h01 of the light-shielding layer 10 in the first region Q11 is greater than the thickness h02 of the light-shielding layer 10 in the second region Q12, it can also be reflected that at least a portion of the sidewalls of the light-emitting element LD in the first region Q11 and at least the sidewalls of the light-emitting element LD in the second region Q12 are both covered by the light-shielding layer 10. For example, please refer to Fig.11 , Fig.11 Shown Fig. 9 Another CC cross-sectional view of the display panel. Please refer to Fig. 9 , Fig.10 and Fig.11In an optional embodiment of the present disclosure, the display panel includes a plurality of first regions Q11 and a plurality of second regions Q12. When the thickness h01 of the light shielding layer 10 in the first region Q11 is greater than the thickness h02 of the light shielding layer 10 in the second region Q12, and light emitting elements LD are disposed in both the first region Q11 and the second region Q12, the side walls of at least some of the light emitting elements LD among the plurality of light emitting elements LD are in contact with the light shielding layer 10. In the present disclosure, the thickness h01 of the light shielding layer 10 in the first region Q11 is greater than the thickness h02 of the light shielding layer 10 in the second region Q12, which means that the top surface of the light shielding layer 10 in the first region Q11 is higher than the top surface of the light shielding layer 10 in the second region Q12. At this time, at least the light shielding layer 10 in the first region Q11 covers the side walls of the light emitting elements LD in the first region Q11, that is, the light shielding layer 10 is in contact with the side walls of the light emitting elements LD, so that the thickness of the light shielding layer 10 in the first region Q11 is larger. For the second region Q12, its light-shielding layer 10 may not cover the side wall of the light-emitting element LD, that is, the light-shielding layer 10 does not contact the side wall of the light-emitting element LD. At this time, the thickness of the light-shielding layer 10 located in the second region Q12 is less than the thickness of the light-shielding layer 10 located in the first region Q11, so as to reduce the brightness of the light-emitting element LD in the first region Q11 and balance the brightness difference of the light-emitting elements LD with different luminous efficiencies in the first region Q11 and the second region Q12. In addition, in some other embodiments, for the second zone Q12, its light shading layer 10 may also cover the side wall of the light emitting element LD, that is, the light shading layer 10 is in contact with the side wall of the light emitting element LD. At this time, as long as the thickness of the light shading layer 10 in contact with the side wall of the light emitting element LD in the second zone Q12 is less than the thickness of the light shading layer 10 in contact with the side wall of the light emitting element LD in the first zone Q11, the brightness of the light emitting element LD in the first zone Q11 and the second zone Q12 can also be balanced to improve the display brightness uniformity of the first zone Q11 and the second zone Q12 in the display panel.

[0075] Please continue to refer to Figures 9 to 11 In an optional embodiment of the present disclosure, the light-emitting element LD includes a first light-emitting element LD1 located in the first region Q11 and a second light-emitting element LD2 located in the second region Q12, the efficiency of the first light-emitting element LD1 is greater than the efficiency of the second light-emitting element LD2, and the thickness h01 of the light-shielding layer 10 contacting the side wall of the first light-emitting element LD1 is greater than the thickness h02 of the light-shielding layer 10 contacting the side wall of the second light-emitting element LD2.

[0076] Specifically, in the present embodiment, the light emitting colors of the first light emitting element LD1 and the second light emitting element LD2 are different, and the light emitting efficiency of the first light emitting element LD1 is greater than the light emitting efficiency of the second light emitting element LD2. In practical applications, if the light output of the light emitting element LD with high light emitting efficiency accounts for a large proportion, the display panel will have abnormal color display under the white screen display. For example, the light emitting efficiency of the blue light emitting element LD is relatively high. If the light output of the blue light emitting element LD accounts for a large proportion, the display panel will have an abnormal bluish problem under the white screen. Therefore, in the present embodiment, the thickness of the light shading layer 10 of the first region Q11 and the thickness of the light shading layer 10 of the second region Q12 are differentially designed, so that the light shading layer 10 in the first region Q11 contacts the side wall of the first light emitting element LD1 in the first region Q11, and at the same time, the thickness of the light shading layer 10 in contact with the side wall of the first light emitting element LD1 is greater than the thickness of the light shading layer 10 in contact with the side wall of the second light emitting element LD2. This is beneficial to reducing the lateral light output of the first light emitting element LD1 with higher luminous efficiency, so as to reduce the overall brightness of the first light emitting element LD1, balance the difference in luminous brightness between the first light emitting element LD1 with higher luminous efficiency and the second light emitting element LD2 with lower luminous efficiency, thereby helping to improve the overall luminous brightness uniformity of the display panel, and at the same time helping to reduce the phenomenon of abnormal color display under a white screen on the display panel.

[0077] In an optional embodiment of the present disclosure, the first light emitting element LD1 is a blue light emitting element LD, and the second light emitting element LD2 is a red light emitting element LD or a green light emitting element LD. In another optional embodiment of the present disclosure, the first light emitting element LD1 is a green light emitting element LD, and the second light emitting element LD2 is a red light emitting element LD.

[0078] In the above embodiment, only the display panel includes the first light emitting element LD1 and the second light emitting element LD2. In some other embodiments of the present disclosure, the display panel also includes the third light emitting element LD3. Fig.12 , Fig.12 Shown Fig. 9 A DD-direction cross-section of the display panel, please refer to Fig. 9 and Fig.12In this embodiment, the display panel includes a first area Q11, a second area Q12 and a third area Q13, and the first area Q11, the second area Q12 and the third area Q13 are all provided with light-emitting elements LD, which are respectively a first light-emitting element LD1, a second light-emitting element LD2 and a third light-emitting element LD3. The three areas are pixel areas 31 or redundant pixel areas 32 where the light-emitting elements LD are provided. Among the three light-emitting elements LD, the first light-emitting element LD1 has the largest light-emitting efficiency, the second light-emitting element LD2 has the middle light-emitting efficiency, and the third light-emitting element LD3 has the smallest light-emitting efficiency. The thickness of the light-shielding layer 10 located in the first area Q11 is greater than the thickness of the light-shielding layer 10 located in the second area Q12, the thickness of the light-shielding layer 10 located in the second area Q12 is greater than the thickness of the light-shielding layer 10 located in the third area Q13, the light-shielding layer 10 located in the first area Q11 contacts the side wall of the first light-emitting element LD1, and the light-shielding layer 10 located in the second area Q12 contacts the side wall of the first light-emitting element LD1. The shading layer 10 in area Q12 contacts the side wall of the second light-emitting element LD2, and the shading layer 10 in the third area Q13 does not contact the side wall of the third light-emitting element LD3. In this way, the shading layer 10 blocks the most lateral light output of the first light-emitting element LD1, blocks less lateral light output of the second light-emitting element LD2, and does not block the lateral light output of the third light-emitting element LD3. Therefore, it is beneficial to reduce the lateral light output of the first light-emitting element LD1 and the second light-emitting element LD2, and the reduction in lateral light output of the first light-emitting element LD1 is greater than the reduction in lateral light output of the second light-emitting element LD2, and it is beneficial to ensure the lateral light output of the third light-emitting element LD3. In this way, it is beneficial to balance the difference in luminous brightness of the three light-emitting elements LD with different luminous efficiency, improve the overall display brightness uniformity of the display panel, and at the same time help to avoid or reduce the problem of abnormal color display of the display panel under a white screen.

[0079] Fig.13 FIG. 1 is a schematic diagram of a structure of a light emitting element LD provided in an embodiment of the present disclosure, please refer to FIG. Fig.13 In an optional implementation of the present disclosure, please combine Figures 10 to 12 The first region Q11 is provided with a light-emitting element LD, which includes a light-emitting chip 21 and an electrode 22 located on one side of the light-emitting chip 21. The surface of the light-emitting chip 21 facing away from the electrode 22 is a plane. The electrode 22 is located on the side of the light-emitting chip 21 facing the driving layer 01, and is used to form an electrical connection with the driving layer 01.

[0080] In the process of manufacturing the display panel, after the light emitting element LD is bound to one side of the driving tube layer, the film layer in the area where the driving circuit, light emitting element LD and wiring structures are not set in the display panel is removed (for example, only the substrate 00 is retained), and a light-transmitting layer 02 is formed in the corresponding area. For example, please refer to Fig.14 , Fig.14The figure shows a manufacturing process of a display panel. In this process, the light-transmitting layer 02 forms an opening K, and the drive circuit, light-emitting element, wiring and other structures are located in the opening. After this, the light-shielding layer 10 is formed. For example, please refer to Fig.15 , Fig.15 Another manufacturing process diagram of the display panel is shown. In the process of forming the light shielding layer 10, the light shielding layer 10 will completely cover the surface of the light emitting chip 21 away from the electrode 22, the opening formed by the light-transmitting layer 02, and the surface of the light-transmitting layer 02 away from the substrate 00. For further information, please refer to Fig.16 , introduce photolithography and other processes to remove unnecessary light shielding layer 10, for example, at least remove the light shielding layer 10 on the surface of light-transmitting layer 02 and the light shielding layer 10 on the surface of light-emitting chip 21, to form a similar Fig.16 The final structure shown is, Fig.16 Another manufacturing process diagram of the display panel is shown. If the surface of the light-emitting chip 21 away from the electrode 22 is a non-planar structure, for example, there is a concave microstructure on the surface of the light-emitting chip 21, and the light-shielding layer 10 is filled in the concave microstructure, it is not easy to remove this part of the light-shielding layer 10 through the photolithography process, which will affect the forward light output of the light-emitting element LD. Therefore, in this embodiment, when the surface of the light-emitting chip 21 away from the electrode 22 in the light-emitting element LD is set to a planar structure, when it is necessary to remove the light-shielding layer 10 on the surface of the light-emitting chip 21, the removal process is simpler and easier to remove, so it is beneficial to avoid the light-shielding layer 10 remaining on the surface of the light-emitting chip 21, and it is beneficial to ensure the forward light output of the light-emitting chip 21.

[0081] Fig.17 Shown Fig. 9 Another CC cross-sectional view of the display panel. Fig.18 The figure shows the structure of the light emitting element LD. Fig.17 and Fig.18 In an optional embodiment of the present disclosure, a light-emitting element LD is provided in the first region Q11, the light-emitting element LD includes a light-emitting chip 21 and an electrode 22 located on one side of the light-emitting chip 21, the surface of the light-emitting chip 21 away from the electrode 22 includes a patterned microstructure, the light-emitting element LD also includes a color filter layer 23, the color filter layer 23 covers the patterned microstructure, and the surface of the color filter layer 23 away from the light-emitting chip 21 is a plane.

[0082] Before the light-emitting element LD is transferred to the array layer, the light-emitting element LD is a finished product structure. During the manufacturing process of the light-emitting element LD, when a patterned microstructure is set on the surface of the light-emitting chip 21 away from the electrode 22, the light emitted by the light-emitting chip 21 will be refracted by the patterned microstructure, and more light will be emitted toward the front view angle of the light-emitting element LD, which is beneficial to increase the light output of the front view angle of the light-emitting element LD. When a patterned microstructure is set on the surface of the light-emitting chip 21 away from the electrode 22, a color filter layer 23 can be further introduced on the side of the patterned microstructure away from the electrode 22. The color of the color filter layer 23 is the same as the light output color of the light-emitting chip 21, and the surface of the color filter layer 23 away from the light-emitting chip 21 is a plane. At this time, the color filter layer 23, the light-emitting chip 21 and the electrode 22 constitute the light-emitting element LD as a whole. When the light-emitting element LD of this structure is applied to the display panel disclosed in the present invention, when the light-shielding layer 10 is produced and unnecessary light-shielding layer 10 is removed, the light-shielding layer 10 originally located on the flat surface of the color film layer 23 is more easily removed, thereby helping to avoid the light-shielding layer 10 remaining on the light-emitting surface of the light-emitting element LD, thereby helping to increase the light output of the light-emitting element LD at a normal viewing angle and improve the brightness of the light-emitting element LD at a normal viewing angle.

[0083] In an optional embodiment, the light emitting element LD in the display panel of the present disclosure can be embodied as Fig.18 The structure shown in FIG. 1 is used to improve the front viewing angle brightness of each light emitting element LD; of course, in some other optional embodiments, the light emitting element LD in the display panel of the present disclosure can also be embodied as Fig.13 The structure shown in the figure takes into account the brightness of the display panel at a large viewing angle, or some light-emitting elements LD adopt Fig.18 The structure shown in the figure, some light emitting elements LD adopt Fig.13 The structure shown is not specifically limited in the present disclosure.

[0084] Fig.19 Shown Fig. 9 Another CC cross-sectional view of the display panel, please refer to Fig.19 In an optional embodiment of the present disclosure, the light-emitting element LD includes a first light-emitting element LD1 and a second light-emitting element LD2, and the efficiency of the first light-emitting element LD1 is greater than the efficiency of the second light-emitting element LD2; in the first region Q1, the shading layer 10 covers at least a portion of the side walls of the light-emitting chip 21 and the side walls of the color filter layer 23 in the first light-emitting element LD1, and the shading layer 10 does not cover the side walls of the color filter layer 23 in the second light-emitting element LD2.

[0085] In this embodiment, the first light emitting element LD1 and the second light emitting element LD2 are both embodied as Fig.18The structure shown is for illustration purposes. The surface of the light-emitting chip 21 in the first light-emitting element LD1 and the second light-emitting element LD2 facing away from the electrode 22 has a patterned microstructure, the color filter layer 23 is located on the surface of the patterned microstructure facing away from the electrode 22, and the top surface of the color filter layer 23 is a flat surface. The luminous efficiency of the first light-emitting element LD1 is greater than that of the second light-emitting element LD2. In order to balance the difference in luminous brightness between the first light-emitting element LD1 and the second light-emitting element LD2, the light-shielding layer 10 in this embodiment covers the side walls of the light-emitting chip 21 and the side walls of the color filter layer 23 in the first light-emitting element LD1, which is equivalent to blocking the lateral light emission of the light-emitting element LD, thereby reducing the overall brightness of the first light-emitting element LD1. For the second light-emitting element LD2 with lower luminous efficiency, the shading layer 10 does not cover the side walls of the color filter layer 23 of the second light-emitting element LD2. The present embodiment is explained by taking the shading layer 10 only covering part of the side walls of the light-emitting chip 21 in the second light-emitting element LD2 as an example. In this way, the second light-emitting element LD2 still retains the lateral light emission to increase the overall light emission of the second light-emitting element LD2, improve the brightness of the second light-emitting element LD2, balance the difference in luminous brightness between the second light-emitting element LD2 and the third light-emitting element LD3, which is beneficial to improving the overall display brightness uniformity of the display panel.

[0086] In some other embodiments of the present disclosure, for the second light emitting element LD2 with low luminous efficiency, the light shielding layer 10 may also completely expose the side wall of the light emitting chip 21 and the side wall of the color filter layer 23 in the second light emitting element LD2. Fig. 20 , so that the lateral light output of the second light-emitting element LD2 can be further increased to improve the overall brightness of the second light-emitting element LD2, reduce the difference in luminous brightness between the second light-emitting element LD2 and the first light-emitting element LD1, and improve the uniformity of the overall display brightness. Fig. 20 Shown Fig. 9 Another CC cross-sectional view of the display panel.

[0087] It should be noted that the light-emitting element LD includes a light-emitting chip 21 and an electrode 22. The light-emitting electrode 22 is a metal electrode 22. When a shading layer 10 is formed in the opening corresponding to the light-emitting element LD, the shading layer 10 will completely cover the electrode 22 of the light-emitting element LD to prevent the metal electrode 22 from causing reflections and affecting the display effect of the display panel.

[0088] Figure 1 and Figure 3 The top view shown in the figure shows that the pixel area 31 and the redundant pixel area 32 are distributed on both sides of the light-transmitting layer 02 along the first direction D1. The row where the pixel area 31 and the row where the redundant pixel area 32 are located are arranged along the first direction D1, but the present disclosure is not limited to this. For example, please refer to Fig.21 , Fig.21FIG. 1 is another partial top view of the display panel provided by the embodiment of the present disclosure. In the embodiment, the pixel area 31 and the redundant pixel area 32 are arranged along the second direction D2, and the pixel area 31 and the corresponding redundant pixel area 32 are adjacently arranged along the second direction D2. At this time, the distribution of the first area Q1 and the second area Q2 in the embodiment of the present disclosure can also be reflected as follows: Fig. 22 The situation shown, Fig. 22 Shown Fig.21 An EE cross-sectional view of the display panel. Please refer to Fig.21 and Fig. 22 In an optional embodiment of the present disclosure, the first area Q21 is provided with a light-emitting element LD, the first area Q21 includes a pixel area 31 and a redundant pixel area 32, and the second area Q22 is a wiring area 33. The first opening K21 is located in the first area Q21, and the second opening K22 is located in the second area Q22. When the redundant pixel area 32 is arranged on one side of the pixel area 31 along the second direction D2, that is, the pixel area 31 and the redundant pixel area 32 are arranged adjacent to each other, and the distance between the two is closer, which is more conducive to realizing the indiscriminate repair of the non-luminous light-emitting element in the pixel area 31. In the embodiment of the present disclosure, the first area Q1 may include a pixel area 31 and a redundant pixel area 32 at the same time, and the second area Q2 is a routing area 33. At this time, the thickness of the light-shielding layer 10 in the first area Q1 and the second area Q2 are different. Optionally, the thickness h1 of the light-shielding layer 10 in the first area Q1 is less than the thickness h2 of the light-shielding layer 10 in the second area Q2, which can also balance the light-shielding effect of the light-shielding layer 10 in the first area Q1 and the second area Q2, thereby improving the overall contrast consistency of the display panel, thereby facilitating improving the viewing experience of users.

[0089] Fig.23 and Fig.24 The following are schematic diagrams showing the relationship between the light shielding layers in the first zone, the second zone and the third zone of the present disclosure, please refer to Fig.23 In the display panel provided in this embodiment, the first area Q31, the second area Q32 and the third area Q33 are isolated by the light-transmitting layer 02, wherein the first area Q31 is provided with a light-emitting element LD, the second area Q32 is a redundant pixel area where no light-emitting element is provided, and the third area Q33 is a wiring area, and the first area Q31, the second area Q32 and the third area Q33 are all provided with a light-shielding layer 10. Fig.23The cross section in is perpendicular to the plane where the light emitting surface of the display panel is located. In the cross section, optionally, the width of the first area Q31 is equal to the width of the second area Q32, and the width of the second area Q32 is greater than the width of the third area Q33. The thickness h31 of the light shielding layer 10 set in the first area Q31 is less than the thickness h32 of the light shielding layer 10 set in the second area Q32, and the thickness h32 of the light shielding layer 10 set in the second area Q32 is less than the thickness h33 of the light shielding layer 10 set in the third area Q33. That is to say, the thickness of the light shielding layer 10 in the first area Q31, the second area Q32 and the third area Q33 tends to increase. Such a setting is also conducive to balancing the difference in the light shielding effect of the light shielding layer in different areas, improving the contrast consistency of different areas, and then helping to improve the overall display effect of the display panel, so as to improve the viewing experience of the user.
