[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application. The features and exemplary embodiments of various aspects of the present application will be described in detail below.
[0027] As described in the background technology, the environment-integrated display module in the prior art still has some problems with poor display effects. Since the surface monomer transmittance of the prior art is generally lower than 30%, the display transmittance is significantly lower than the transmittance of the display module using the cover plate and polarizer structure, resulting in poor display effects.
[0028] In view of this, the present application provides a display module and a display device, which improves the transmittance of the display module by setting a microlens structure in the epidermis structure of the environmentally integrated display module, setting a graphic opening in the shading layer of the epidermis structure, and setting a reflective layer on the side of the opening, thereby effectively improving the display effect of the display module.

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 on the substrate 100 covers the orthographic projection of the light-emitting layer 111 on the substrate 100.
[0030] The substrate 100 may be a base substrate or an array substrate.

[0032] It can be understood that the light in the direction of large viewing angle refers to the light having a larger angle between the exit direction and the normal of the display panel, and the light in the direction of small viewing angle refers to the light having a smaller angle between the exit direction and the normal of the display panel.

The orthographic projection of the first opening H1 on the substrate 100 covers the orthographic projection of the light-emitting layer 111 on the substrate 100. The second reflective layer 260 is located on the side wall of the first opening H1.
[0074] In this embodiment, a graphic opening is set in the first light shielding layer 230 of the epidermis 20, so as to shield each metal film layer between the substrate 100 and the packaging structure 160 while ensuring the transmittance of the display module, reduce the reflection of light by each metal film layer under strong light environment, and thus effectively alleviate the reflection problem of the display module under strong light. At the same time, a second reflection layer 260 is set on the side wall of the first opening H1, which can reflect the light emitted from the light emitting device 110 to the second reflection layer 260, so that the light originally absorbed by the first light shielding layer 230 is emitted as a small viewing angle light, which can further improve the effective utilization rate of light, increase light extraction, and improve the transmittance of the environment-integrated display module.
[0075] In one embodiment, the opening area of the first opening H1 close to the substrate 100 is smaller than the opening area of the first opening H1 away from the substrate 100. Figure 7 and Figure 8 The first opening H1 is a three-dimensional structure, and the first opening H1 penetrates the first light shielding layer 230 in the thickness direction of the substrate 100. In this case, the opening areas of the first opening H1 on different cross sections parallel to the substrate 100 may be the same or different.
[0076] The display module provided according to 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 A schematic diagram of the cross-sectional structure of a display module provided in the seventh embodiment of the present application is shown in FIG. Figure 7 As shown, in the direction away from the substrate 100, the opening area of the first opening H1 in the direction parallel to the substrate 100 gradually increases. Exemplarily, 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 adjusting the side wall inclination angle of the first opening H1, and changes the light originally emitted from the large viewing angle direction to the light from the small viewing angle direction, which can further improve the effective utilization rate of the light, increase the light extraction, and improve the transmittance of the environment-integrated display module.
[0078] In one embodiment, the epidermis 20 further includes a base material layer 200 , which is located on a side of the first light shielding layer 230 close to the substrate 100 . The base material layer 200 provides support for the structure of the entire epidermis 20 .

[0081] In one embodiment, the texture layer 220 is formed by screen ink printing technology. The texture layer prepared by screen ink printing technology can play a decorative and concealing role, so that the display module is integrated with the interior of the venue, and the overall style is more coordinated and consistent, which 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 a side of the texture layer 220 facing away from the substrate 100 .

The light emitting device 110 includes a light emitting layer 111. The skin 20 includes a first light shielding layer 230, the first light shielding layer 230 includes a first light shielding portion 231, and the first light shielding portion 231 has a first opening H1. The orthographic projection of the first opening H1 on the substrate 100 covers an opening area on one side of the light emitting layer 111 that is smaller than the opening area on the side away from the substrate 100.
[0085] This embodiment provides a graphic opening on the first light shielding layer 230 to shield each metal film layer in the display module while ensuring the transmittance of the display module, thereby reducing the reflection of light by each metal film layer in a strong light environment, thereby effectively alleviating the reflection problem of the display module under strong light. In addition, this embodiment provides a first opening with an opening area on the side close to the substrate 100 smaller than the opening area on the side away from the substrate 100. Compared with the vertical side wall, it 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 a packaging structure 160 located on a side of the light emitting device 110 away from the substrate 100 , and a second light shielding layer 170 located between the packaging structure 160 and the light emitting device 110 .
