[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Many specific details are set forth in the following detailed description to provide a comprehensive understanding of this application. However, it will be apparent to those skilled in the art that this application can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this application by illustrating examples. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The features and exemplary embodiments of various aspects of this application will be described in detail below.

[0027] As described in the background section, existing integrated display modules still suffer from some issues related to poor display performance. Because the transmittance of individual skin cells in existing technologies is generally below 30%, the overall transmittance is significantly lower than that of display modules using cover plates and polarizers, resulting in poor display quality.

[0028] In view of this, this application provides a display module and a display device, which improves the transmittance of the display module by setting a microlens structure in the skin structure of the environmentally integrated display module, setting a patterned opening in the light-shielding layer of the skin structure, and setting a reflective layer on the side of the opening, thereby effectively improving the display effect of the display module.

[0029] Figure 1 This is a schematic cross-sectional view of the display module provided in the first embodiment of this application. Figure 1As shown, the display module includes a display panel 10 and a skin 20. The display panel 10 includes a substrate 100 and at least one light-emitting device 110. The light-emitting device 110 is located on one side of the substrate 100, and the skin 20 is located on the display side of the display panel 10. The light-emitting device 110 includes a light-emitting layer 111. The skin 20 includes at least one first microlens 210, and the orthographic projection of the first microlens 210 onto the substrate 100 covers the orthographic projection of the light-emitting layer 111 onto the substrate 100.

[0030] The substrate 100 can be a substrate substrate or an array substrate. An array substrate refers to a substrate structure that includes a substrate substrate and an array of pixel circuits formed on the substrate substrate. The pixel circuits are electrically connected to the light-emitting device 110 and are used to drive the light-emitting device 110 to emit light at a predetermined brightness to realize the display function.

[0031] This embodiment improves the display effect of the integrated environmental display module by setting a microlens structure in the skin structure of the integrated environmental display module, which converges the light emitted by the light-emitting device 110 and refracts some of the light from the large viewing angle direction into light emitted from the small viewing angle direction.

[0032] It is understandable that light rays from a wide viewing angle refer to light rays with a larger angle between the emitted direction and the normal of the display panel, while light rays from a narrow viewing angle refer to light rays with a smaller angle between the emitted direction and the normal of the display panel.

[0033] In one embodiment, continue to refer to Figure 1 As shown, the light-emitting device 110 further includes a first electrode 112 and a second electrode 113. The first electrode 112 is located on the side of the light-emitting layer 111 facing away from the substrate 100. The first electrodes 112 of multiple light-emitting devices 110 are interconnected to form a full-surface electrode. The second electrode 113 is located on the side of the light-emitting layer 111 close to the substrate 100. The second electrodes 113 of different light-emitting devices 110 are independent of each other. Exemplarily, the first electrode 112 is a cathode, and the second electrode 113 is an anode. Exemplarily, the light-emitting device 110 may also include a hole functional layer located between the anode and the light-emitting layer 111, such as at least one of a hole transport layer and a hole injection layer. The light-emitting device 110 may also include an electronic functional layer located between the cathode and the light-emitting layer 111, such as at least one of an electron transport layer and an electron injection layer.

[0034] In one embodiment, continue to refer to Figure 1 As shown, the first microlens 210 protrudes to the side opposite to the substrate 100.

[0035] In one embodiment, continue to refer to Figure 1As shown, the skin also includes a texture layer 220, at least a portion of which is located between adjacent first microlenses 210. For example, the texture layer 220 includes a groove 221, the opening of which is formed on the side of the texture layer 220 near the substrate 100, and the first microlenses 210 are located within the groove 221.

[0036] In one embodiment, the shape of the first microlens 210 is as follows: Figure 1 Besides the shape shown, it can also be an irregular shape, such as an irregular polygon, etc. Those skilled in the art can design it according to actual needs.

[0037] In one embodiment, the first microlens 210 is typically made of an optical-grade polymer material, such as polyimide, polyethylene terephthalate, or polymethyl methacrylate.

[0038] In one embodiment, the texture pattern of the texture layer 220 includes, but is not limited to, wood grain, leather grain, fabric grain, and brushed metal grain.

[0039] In one embodiment, the texture layer 220 is formed by screen printing technology. The texture layer prepared by screen printing technology can play a decorative and concealing role, so that the display module can be integrated with the interior decoration of the venue, the overall style is more harmonious and consistent, and it is more in line with the aesthetic needs of modern users.

[0040] In one embodiment, such as Figure 1 As shown, the outer skin 20 of the display module also includes a first light-shielding layer 230, located on the side of the texture layer 220 near the substrate 100. The first light-shielding layer 230 includes a first light-shielding portion 231, which has a first opening H1. The orthographic projection of the first opening H1 onto the substrate 100 covers the orthographic projection of the light-emitting layer 111 onto the substrate 100. For example, the material of the first light-shielding portion 231 is, for example, black pigment. For example, black pigment includes carbon black, graphite, etc. For example, the first opening H1 and the first microlens 210 correspond one-to-one.

[0041] In one embodiment, the first light-shielding layer 230 further includes a first light-transmitting portion 232, which fills the first opening H1, and at least a portion of the first microlens 210 is located on the side of the first light-transmitting portion 232 facing away from the substrate. Exemplarily, the material of the first light-transmitting portion 232 includes photoresist. In this case, the first light-shielding portion 231 is used to block light emitted from the display panel, and the first light-transmitting portion 232 is used to transmit light through the display panel. Thus, the first light-shielding portion 231 and the first light-transmitting portion 232 cooperate to limit the light emission range of the display panel 10. Exemplarily, the entire first microlens 210 is located on the side of the first light-transmitting portion 232 facing away from the substrate; or, the first microlens 210 extends from the side of the first light-transmitting portion 232 facing away from the substrate to cover a portion of the first light-shielding portion 231.

[0042] This embodiment achieves the goal of reducing the reflection of light by each metal film layer in the display module under strong light environment while ensuring the transmittance of the display module, by setting patterned openings in the first light-shielding layer 230 of the skin 20, and the area of ​​the openings being greater than or equal to the area of ​​the pixel opening where the light-emitting device 110 is located. This effectively alleviates the reflection problem of the display module under strong light.

[0043] In one embodiment, the distance D between the edge line of the orthographic projection of the first opening H1 on the substrate 100 and the edge line of the orthographic projection of the light-emitting layer 111 on the substrate 100 is greater than or equal to 7 micrometers and less than or equal to 17 micrometers. For example, the distance D is 7 micrometers, 12 micrometers, 17 micrometers, etc.

[0044] In one embodiment, the orthographic projection of the first microlens 210 onto the substrate 100 and the orthographic projection of the first opening H1 onto the substrate 100 at least partially overlap.

[0045] In one embodiment, the orthographic projection of the first microlens 210 onto the substrate 100 and the orthographic projection of the first opening H1 onto the substrate 100 completely overlap.

[0046] In one embodiment, the orthographic projection of the first opening H1 onto the substrate 100 is circular. For example, the difference between the diameter of the orthographic projection of the first opening H1 onto the substrate 100 and the diameter of the orthographic projection of the light-emitting device 110 onto the substrate 100 can be 10 micrometers, 15 micrometers, or 20 micrometers, etc.

[0047] In one embodiment, the texture layer 220 is a core film layer that provides an environmental integration effect, used to achieve an environmental integration display effect.

[0048] In one embodiment, the texture pattern of the texture layer 220 includes, but is not limited to, wood grain, leather grain, fabric grain, and brushed metal grain.

[0049] In one embodiment, the texture layer 220 is formed by screen printing technology. The texture layer prepared by screen printing technology can play a decorative and concealing role, so that the display module can be integrated with the interior decoration of the venue, the overall style is more harmonious and consistent, and it is more in line with the aesthetic needs of modern users.

[0050] In one embodiment, the skin 20 further includes a substrate layer 200 located on the side of the first light-shielding layer 230 near the substrate 100, and the substrate layer 200 provides support for the overall structure of the skin 20.

[0051] In one embodiment, the skin 20 further includes a protective layer 240 located on the side of the texture layer 220 away from the substrate 100, for protecting the texture layer 220 from external wear and other damage, thereby reducing the environmental integration effect of the display module.

[0052] In one embodiment, the transmittance of the epidermis 20 is greater than 70%; and / or, the reflectance of the epidermis 20 is greater than or equal to 9% and less than or equal to 12.5%. For example, the transmittance of the epidermis 20 is 70%, 80%, or 90%, and the reflectance of the epidermis 20 is 9%, 10%, 11%, or 12.5%.

[0053] In one embodiment, the skin 20 further includes an adhesive layer 250, an adhesive substrate layer 200, and a display panel 10.

[0054] Figure 2 This is a schematic cross-sectional view of the display module provided in the second embodiment of this application. Figure 2 The display panel shown and Figure 1 The difference in the display panel shown is that, in this embodiment, the display panel 10 further includes an encapsulation structure 160. The encapsulation structure 160 is located on the side of the light-emitting device 110 facing away from the substrate 100.

[0055] In one embodiment, the display panel 10 further includes a second light-shielding layer 170 located on the side of the encapsulation structure 160 near the substrate 100. The second light-shielding layer 170 includes a second light-shielding portion 171 having a second opening H2. Exemplarily, the material of the second light-shielding portion 171 is ink, carbon black, etc.

[0056] In one embodiment, the second light-shielding layer 170 further includes a second light-transmitting portion 172 that fills the second opening H2. For example, the material of the second light-transmitting portion 172 is photoresist.

[0057] Figure 3 This is a schematic cross-sectional view of the display module provided in the third embodiment of this application. Figure 3 The display module and Figure 1The difference in the display module shown is that, in this embodiment, the display panel 10 further includes a second microlens 150 located on the side of the light-emitting device 110 facing away from the substrate 100. The orthogonal projection of the second microlens 150 onto the substrate 100 overlaps with the orthogonal projection of the light-emitting layer 111 onto the substrate 100. By providing a microlens structure in the display panel 10 of the ambient light integrated display module, the light emitted from the light-emitting device 110 is focused, improving the transmittance of the ambient light integrated display module and thus effectively improving the display effect of the display panel.

[0058] In one embodiment, the material of the second microlens 150 is typically an optical-grade polymer material, such as polyimide, polyethylene terephthalate, polymethyl methacrylate, etc.

[0059] In one embodiment, the display panel 10 further includes an encapsulation structure 160. The encapsulation structure 160 is located on the side of the light-emitting device 110 facing away from the substrate 100, and the second microlens 150 is located between the encapsulation structure 160 and the light-emitting device 110. This embodiment, by providing the second microlens 150 on the side of the encapsulation structure 160 closer to the light-emitting device 110, further achieves the convergence of some of the light emitted from the light-emitting device 110, improving the transmittance of the integrated environmental display module, thereby effectively improving the display effect of the display module.

[0060] In one embodiment, the display panel 10 further includes a second light-shielding layer 170 located on the side of the encapsulation structure 160 near the substrate 100. The second light-shielding layer 170 includes a second light-shielding portion 171 having a second opening H2. Exemplarily, the material of the second light-shielding portion 171 is ink, carbon black, etc. The orthographic projection of the second opening H2 onto the substrate 100 and the orthographic projection of the second microlens 150 onto the substrate 100 at least partially overlap.

[0061] For example, the orthogonal projection of the second microlens 150 on the substrate 100 covers the orthogonal projection of the second opening H2 on the substrate 100; or, the orthogonal projection of the second microlens 150 on the substrate 100 and the orthogonal projection of the second opening H2 on the substrate 100 overlap.

[0062] In one embodiment, the orthographic projection of the second opening H2 on the substrate 100 covers the orthographic projection of the light-emitting layer 111 on the substrate 100.

[0063] In one embodiment, the second light-shielding layer 170 further includes a second light-transmitting portion 172 filling the second opening H2, with at least a portion of the second microlens 150 located on the side of the second light-transmitting portion 172 facing away from the substrate. Exemplarily, the material of the second light-transmitting portion 172 is photoresist. Exemplarily, the entire second microlens 150 is located on the side of the second light-transmitting portion 172 facing away from the substrate; or, the second microlens 150 extends from the side of the second light-transmitting portion 172 facing away from the substrate to cover a portion of the second light-transmitting portion 172.

[0064] This embodiment provides patterned openings in the second light-shielding layer 170 of the display panel 10, with the opening area being greater than or equal to the area of ​​the pixel opening where the light-emitting device 110 is located. This achieves the goal of ensuring the transmittance of the display module while shielding each metal film layer between the substrate 100 and the packaging structure 160, reducing the reflection of light by each metal film layer under strong light conditions, thereby effectively mitigating the reflection problem of the display module under strong light.

[0065] In one embodiment, the encapsulation structure 160 is used to encapsulate the light-emitting device 110 to prevent water and oxygen from corroding the light-emitting device 110 in the external environment, thereby extending the service life of the light-emitting device 110. The encapsulation structure 160 may include a first inorganic encapsulation layer, an organic encapsulation layer, and a second inorganic encapsulation layer sequentially stacked on the side of the light-emitting device 110 away from the substrate 100. The first and second inorganic encapsulation layers act as barriers against external water and ions, while the organic encapsulation layer can be fabricated using coating or inkjet printing processes to achieve planarization.

[0066] Figure 4 This is a schematic cross-sectional view of the display module provided in the fourth embodiment of this application. Figure 4 The display module and Figure 1 , Figure 2 and Figure 3 The difference between the display modules shown is that, with Figure 2 Taking the display module shown as an example, in this embodiment, the first electrodes 112 of adjacent light-emitting devices 110 are spaced apart.

[0067] In one embodiment, the orthogonal projection of the first electrode 112 onto the substrate 100 is located within the orthogonal projection range of the first microlens 210 onto the substrate 100.

[0068] In one embodiment, the orthographic projection of the second electrode 113 on the substrate 100 coincides with the orthographic projection of the first microlens 210 on the substrate 100; or, the orthographic projection of the second electrode 113 on the substrate 100 covers the orthographic projection of the first microlens 210 on the substrate 100.

[0069] Figure 5 This is a schematic cross-sectional view of the display module provided in the fifth embodiment of this application. Figure 5The difference between the display module shown and the display module provided in any of the above embodiments is that, in this embodiment, the display panel 10 further includes a pixel definition layer 120, a first reflective layer 130, and an insulating layer 140. The pixel definition layer 120 has pixel openings, and the light-emitting layer 111 is located within the pixel openings. The first reflective layer 130 is located on the sidewall of the pixel opening, and the insulating layer 140 is located between the first reflective layer 130 and the light-emitting layer 111.

[0070] In this embodiment, by setting a first reflective layer 130 inside the pixel opening, the light emitted from the light-emitting device 110 onto the first reflective layer 130 can be reflected, thereby changing the light that was originally absorbed by the pixel definition layer 120 or emitted from a wide viewing angle direction into light from a narrow viewing angle direction, which can further improve the effective utilization rate of light, increase light extraction, and improve the transmittance of the environmental integrated display module.

[0071] In one embodiment, the first reflective layer 130 includes a metal layer. The metal layer can be formed by depositing a metal coating on the surface of the pixel definition layer 120, and the metal material can include silver, aluminum, etc.

[0072] In one embodiment, the insulating layer 140 is made of a transparent material, which increases the transmittance of light therein.

The display panel 10 includes a substrate 100 and a light-emitting device 110 located on one side of the substrate 100. The skin 20 is located on the display side of the display panel 10. The skin 20 includes a first light-shielding layer 230 and a second reflective layer 260. The first light-shielding layer 230 encloses a first opening H1, and the orthographic projection of the first opening H1 on the substrate 100 covers the orthographic projection of the light-emitting layer 110 on the substrate 100. The second reflective layer 260 is located on the sidewall of the first opening H1.

[0074] This embodiment achieves this by providing patterned openings in the first light-shielding layer 230 of the skin 20, thus ensuring the transmittance of the display module while shielding the various metal film layers between the substrate 100 and the packaging structure 160. This reduces the reflection of light by the metal film layers under strong light conditions, effectively mitigating the glare problem of the display module under strong light. Simultaneously, a second reflective layer 260 is provided on the sidewall of the first opening H1, which reflects the light emitted from the light-emitting device 110 onto the second reflective layer 260. This transforms the light originally absorbed by the first light-shielding layer 230 into narrow-angle light, further improving the effective utilization of light, increasing light extraction, and enhancing the transmittance of the environmentally integrated display module.

[0075] In one embodiment, the opening area of ​​the first opening H1 on the side closer to the substrate 100 is smaller than the opening area on the side away from the substrate 100, specifically as follows: Figure 7 and Figure 8 As shown, the first opening H1 is a three-dimensional structure that penetrates the first light-shielding layer 230 in the thickness direction of the substrate 100. In this case, the opening area of ​​the first opening H1 can be the same or different on different cross sections parallel to the substrate 100.

[0076] The display module provided in this embodiment may also include the technical details of the display module provided in any of the above embodiments, which will not be repeated here.

[0077] Figure 7 This is a schematic cross-sectional view of the display module provided in the seventh embodiment of this application, as shown below. Figure 7 As shown, in the direction away from the substrate 100, the opening area of ​​the first opening H1 gradually increases in the direction parallel to the substrate 100. For example, in the direction perpendicular to the substrate 100, the cross-sectional shape of the first opening H1 is an inverted trapezoid. This embodiment adjusts the light extraction angle of the first opening H1 by controlling the sidewall tilt angle, changing the light emitted from a wide viewing angle to a narrow viewing angle, thereby further improving the effective utilization of light, increasing light extraction, and improving the transmittance of the integrated environmental display module.

[0078] In one embodiment, the skin 20 further includes a substrate layer 200 located on the side of the first light-shielding layer 230 near the substrate 100, and the substrate layer 200 provides support for the overall structure of the skin 20.

[0079] In one embodiment, the skin 20 further includes a texture layer 220, which is a core film layer that provides an environmental integration effect for achieving an environmental integration display effect.

[0080] In one embodiment, the texture pattern of the texture layer 220 includes, but is not limited to, wood grain, leather grain, fabric grain, and brushed metal grain.

[0081] In one embodiment, the texture layer 220 is formed by screen printing technology. The texture layer prepared by screen printing technology can play a decorative and concealing role, so that the display module can be integrated with the interior decoration of the venue, the overall style is more harmonious and consistent, and it is more in line with the aesthetic needs of modern users.

[0082] In one embodiment, the skin 20 further includes a protective layer 240 located on the side of the texture layer 220 opposite to the substrate 100.

[0083] The display module provided in this embodiment may also include the technical details of the display module provided in any of the above embodiments, which will not be repeated here.

[0084] Figure 8 This is a schematic cross-sectional view of the display module provided in the eighth embodiment of this application. Figure 8 As shown, the display module includes a display panel 10 and a skin 20. The display panel 10 includes a substrate 100 and a light-emitting device 110 located on one side of the substrate 100. The skin 20 is located on the display side of the display panel 10. The light-emitting device 110 includes a light-emitting layer 111. The skin 20 includes a first light-shielding layer 230, which includes a first light-shielding portion 231 with a first opening H1. The area of ​​the first opening H1 projected onto the substrate 100 covering the side of the light-emitting layer 111 is smaller than the area of ​​the opening on the side facing away from the substrate 100.

[0085] This embodiment achieves the goal of shielding each metal film layer in the display module while ensuring the transmittance of the display module by providing a patterned opening on the first light-shielding layer 230. This reduces the reflection of light by each metal film layer under strong light conditions, thereby effectively mitigating the glare problem of the display module under strong light. In addition, this embodiment sets the opening area on the side of the first opening closer to the substrate 100 to be smaller than the opening area on the side away from the substrate 100. Compared with the vertical sidewall, this can effectively increase light extraction while reducing the reflection of light by the metal film layer, thereby further improving the transmittance of the display module.

[0086] In one embodiment, the display panel 10 further includes an encapsulation structure 160 located on the side of the light-emitting device 110 away from the substrate 100, and a second light-shielding layer 170 located between the encapsulation structure 160 and the light-emitting device 110.
