[0056] Unless otherwise defined, the technical terms or scientific terms used in the embodiments of this specification shall have the common meanings understood by persons with ordinary skills in the field to which this specification belongs. The words "first", "second" and similar words used in the embodiments of this specification do not indicate any order, quantity or importance, but are only used to avoid confusion of constituent elements.

[0057] Unless the context requires otherwise, throughout the specification, "plurality" means "at least two", and "including" is interpreted as an open, inclusive meaning, that is, "including, but not limited to". In the description of the specification, the terms "one embodiment", "some embodiments", "exemplary embodiments", "examples", "specific examples" or "some examples" are intended to indicate that a particular feature, structure, material or characteristic associated with the embodiment or example is included in at least one embodiment or example of the specification. The schematic representation of the above terms does not necessarily refer to the same embodiment or example.

[0058] The following will be combined with the drawings in the embodiments of this specification to clearly and completely describe the technical solutions in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this specification.

[0059] With the advancement of science and technology, people have higher and higher requirements for display modules, among which thinness and narrow frame are the mainstream trends of display modules. At the same time, with the rapid development of smart travel and smart cockpit technology in recent years, people have higher and higher requirements for the integration of display and environment.

[0060] Therefore, how to achieve the integrated fusion of display and environment of display module has attracted much attention as an important means to improve user satisfaction.

[0061] To this end, the present application provides a solution that can achieve the integrated fusion of the display of the display module and the environment. By setting an optical structure layer, and the light transmittance of the part of the optical structure layer located on the side away from the light-emitting device is different from the light transmittance of the part located between two adjacent light-emitting devices, when the display module is off, the area corresponding to the light-emitting device and the area corresponding to the adjacent light-emitting devices can have texture effects with different degrees of brightness, so that the display module can be better integrated with the surrounding environment, thereby enhancing the user's visual and tactile experience and meeting the user's needs for the integration of display and environment.

[0062] Specifically, as an optional implementation of the contents disclosed in this application, an embodiment of this application provides a display module. Figure 1 This is a structural schematic diagram of a display module provided by an embodiment of the present application. As shown in the figure, the display module may at least include: a substrate 10, a light-emitting device layer 11 and an optical structure layer 12.

[0063] The substrate 10 mainly plays the role of supporting and bearing. Specifically, the substrate 10 may include a rigid substrate such as a glass substrate or a silicon substrate, or may include a flexible substrate such as stainless steel (SUS) or flexible polyimide (PI). That is, the display module in the embodiment of the present application may include a non-bendable rigid display module, or may include a bendable flexible display module.

[0064] The light emitting device layer 11 is located on one side of the substrate 10 and may include a plurality of light emitting devices Q arranged at intervals.

[0065] like Figure 2 As shown, the light emitting device Q may include a first electrode Q1 , a light emitting functional layer Q2 , and a second electrode Q3 which are sequentially stacked in a direction away from the substrate 10 .

[0066] Specifically, the light-emitting functional layer Q2 may include a hole injection layer, a hole transport layer, a light-emitting material layer, an electron transport layer and an electron injection layer stacked in sequence on the side of the first electrode Q1 away from the substrate 10. The second electrode Q3 is located on the side of the electron injection layer away from the substrate.

[0067] Among them, the light-emitting material layer may include a material having electroluminescence (EL) properties (hereinafter referred to as the light-emitting material). The first electrode Q1 may also be called an anode, which is used to provide holes to the light-emitting material layer, and the second electrode Q3 may also be called a cathode, which is used to provide electrons to the light-emitting material layer. The holes provided by the first electrode Q1 and the electrons provided by the second electrode Q3 can excite the light-emitting material of the light-emitting material layer to emit light after the light-emitting material layer is recombined. The hole injection layer and the hole transport layer can be made of a material with high hole mobility, so that the holes generated by the first electrode Q1 can be better transferred to the light-emitting material layer. Similarly, the electron injection layer and the electron transport layer can be made of a material with high electron mobility, so that the electrons generated by the second electrode Q3 can be better transferred to the light-emitting material layer.

[0068] The optical structure layer 12 is located on a side of the light emitting device Q away from the substrate 10 , and is partially filled between two adjacent light emitting devices Q.

[0069] The light transmittance of the portion of the optical structure layer 12 located away from the light emitting device Q is different from the light transmittance of the portion located between two adjacent light emitting devices Q.

[0070] It is important to understand that objects of a single color have different light transmittances, and the depth of color they present under natural light is also different.

[0071] Therefore, when the display module is in the off state, the color depth of the portion of the optical structure layer 12 located on the side away from the light-emitting device Q is different from that of the portion located between two adjacent light-emitting devices Q. That is, on the display interface of the display module, the portion of the corresponding optical structure layer 12 located on the side away from the light-emitting device Q and the portion located between two adjacent light-emitting devices Q will present different light and dark texture effects, which can form a better integration with the environment, thereby meeting the user's demand for the integration of display and environment and enhancing the user's visual and tactile experience.

[0072] In some embodiments, Figure 3 and Figure 4 As shown, the optical structure layer 12 may include an encapsulation layer 121 and a first shielding layer 122 .

[0073] Part of the encapsulation layer 121 is located on the side of the light-emitting device Q away from the substrate 10 , and part of the encapsulation layer 121 is wrapped around the circumference of the plurality of light-emitting devices Q and is sealed and connected to the surface of the substrate 10 close to the light-emitting device Q.

[0074] The encapsulation layer 121 can be used to encapsulate the light emitting device Q, thereby protecting the light emitting device Q and preventing the light emitting device Q from leaking or being damaged, thereby ensuring the display effect of the display module.

[0075] The first shielding layer 122 may include a plurality of shielding portions 12A, which are disposed on a surface of one side of the substrate 10 , and the plurality of shielding portions 12A are respectively located between side walls of two adjacent light emitting devices Q.

[0076] The setting of the first shielding layer 122 can make the light transmittance of the part of the optical structure layer 12 located on the side away from the light-emitting device Q different from the light transmittance of the part located between two adjacent light-emitting devices Q, so that the display module has a texture effect with different light and dark when the screen is off.

[0077] Furthermore, by disposing the shielding portion 12A between the side walls of two adjacent light emitting devices Q, it is also possible to avoid blocking of the outgoing light due to the existence of the shielding portion 12A, thereby ensuring the display effect of the display module.

[0078] Furthermore, the material of the first shielding layer 122 can be black optical glue, that is, the first shielding layer 122 can be a black optical glue layer, and accordingly, the shielding portion 12A is a black optical glue portion. By using black optical glue as the material of the first shielding layer 122, the shielding property of the black optical glue can be utilized to improve the performance of the shielding portion 12A in preventing cross-light interference. At the same time, the light absorption property of the black optical glue can also be utilized to absorb ambient light, thereby improving the contrast of the display module and further improving the display effect of the display module.

[0079] In this embodiment, the shielding portion 12A can not only isolate adjacent light-emitting devices Q, control the light emission direction, and prevent cross-light interference between adjacent light-emitting devices Q, but also absorb ambient light, reduce reflection, and improve contrast, thereby eliminating the need to set up an optical adhesive layer and a polarizer, greatly reducing the thickness of the display module, effectively improving the thinness of the display module, and at the same time, simplifying the preparation process and improving the preparation efficiency.

[0080] In addition, by providing a shielding portion 12A between adjacent light-emitting devices Q, when the display module is not working, there can be a texture effect with different degrees of brightness between the area corresponding to the light-emitting device Q and the area corresponding to the shielding portion 12A, so that the display module can be better integrated with the surrounding environment, thereby enhancing the user's visual and tactile experience and meeting the user's demand for the integration of display and environment.

[0081] In some embodiments, Figure 3As shown, the encapsulation layer 121 may include a plurality of encapsulation parts 12B arranged at intervals. The plurality of encapsulation parts 12B are wrapped around the circumference of the plurality of light-emitting devices Q one by one, and are sealed and connected to the surface of the substrate 10 on one side close to the light-emitting device Q. In this way, the encapsulation parts 12B can be used to realize independent encapsulation of the light-emitting device Q, thereby preventing the light-emitting device Q from lateral leakage, or water vapor invading from the side of the light-emitting device Q to cause damage to the light-emitting device Q, thereby realizing comprehensive protection of the light-emitting device Q, thereby improving the effectiveness of the encapsulation and the safety of the light-emitting device Q.

[0082] The shielding portion 12A may be located between the side walls of two adjacent packaging portions 12B, so that while the packaging portion 12B is used to protect the corresponding light-emitting device Q, the shielding portion 12A is used to prevent cross-talk interference and improve the display effect of the display module.

[0083] Specifically, Figure 3 As shown, the surface of the shielding portion 12A facing away from the substrate 10 can be flush with the surface of the packaging portion 12B facing away from the substrate 10, thereby facilitating the flattening of the film layer of the subsequent packaging layer 121 facing away from the substrate 10 and improving the product yield.

[0084] When used, each packaging part 12B of the packaging layer 121 can be formed by combining a chemical vapor deposition (CVD) method and an etching method. The material of the packaging part 12B can be an inorganic insulating material.

[0085] Of course, the present application is not limited thereto, and in some other implementations, the material of the packaging portion 12B may also be an organic insulating material. Specifically, it may be set according to actual packaging requirements and technical needs.

[0086] In some embodiments, Figure 4 As shown, part of the encapsulation layer 121 may be located on the side of the shielding portion 12A away from the substrate 10, part of the encapsulation layer 121 wraps around the plurality of shielding portions 12A, and is sealed and connected to the surface of the substrate 10 close to the shielding portion 12A.

[0087] In this way, the encapsulation layer 121 can cover each light emitting device Q and each shielding portion 12A at the same time, thereby achieving comprehensive encapsulation of the light emitting device Q and the shielding portion 12A.

[0088] In some embodiments, Figure 5 and Figure 6As shown, the display module may include a display area AA and a frame area BB, wherein the display area AA is used for light-emitting display, and accordingly, the light-emitting device layer 11 and the first shielding layer 122 are both located in the display area AA. The frame area BB is arranged around the display area AA, and only a partial display area AA and the frame area BB are shown in the figure, wherein the frame area BB can be used for setting metal wiring.

[0089] Specifically, the optical structure layer 12 may further include a second shielding layer 123. The second shielding layer 123 is located on one side of the substrate 10 and is disposed in the same layer as the first shielding layer 122. The second shielding layer 123 is located in the frame area BB.

[0090] like Figure 5 and Figure 6 As shown, the display module may further include a circuit layer 15 located on one side of the substrate 10, a light emitting device layer 11 and a first shielding layer 122 are provided on the side of the circuit layer 15 located in the display area AA away from the substrate 10, and a second shielding layer 123 is provided on the side of the circuit layer 15 located in the frame area BB away from the substrate 10. The circuit layer 15 located in the frame area BB has a plurality of metal traces. The second shielding layer 123 is provided in the frame area BB, and the dense metal traces can be shielded by the second shielding layer 123.

[0091] Specifically, the orthographic projection of the second shielding layer 123 on the substrate 10 covers the orthographic projection of the frame area BB on the substrate 10 .

[0092] In the related art, a cover plate coated with ink is usually used to block the metal traces in the frame area or absorb the light reflected by the metal traces. However, there are processing tolerances in the production of the cover plate ink and there are also fitting tolerances in the cover plate bonding, which results in that the cover plate ink cannot be infinitely compressed, that is, the display module frame cannot be infinitely compressed, which greatly affects the reduction of the display module frame.

[0093] In the implementation of the present application, a second shielding layer 123 is provided in the border area BB to shield the metal wiring and absorb the light reflected by the metal wiring. At the same time, the screen frame can be made the module frame, thereby minimizing the frame of the display module and realizing a narrow frame design of the display module.

[0094] During implementation, the surface of the second shielding layer 123 away from the substrate 10 is flush with the surface of the encapsulation layer 121 away from the substrate 10 .

[0095] For example, Figure 5 As shown, the surface of the first shielding layer 122 away from the substrate, the surface of the second shielding layer 123 away from the substrate 10, and the surface of the encapsulation layer 121 away from the substrate are all kept flush. Figure 6As shown, when part of the encapsulation layer 121 is wrapped around the peripheral sides of the plurality of shielding portions 12A, only the surface of the encapsulation layer 121 away from the substrate 10 is flush with the surface of the second shielding layer 123 away from the substrate.

[0096] In this way, it can be ensured that the surface of the optical structure layer 12 away from the substrate 10 is in a planar state, thereby facilitating the planarization of the display module and improving the product yield.

[0097] In some implementations, the second shielding layer 123 may also be made of black optical glue, so that the second shielding layer 123 can better shield the metal wiring and absorb ambient light and reflected light from the metal wiring.

[0098] Since the second shielding layer 123 mainly functions to shield metal wiring, when the first shielding layer 122 and the second shielding layer 123 are both made of black optical adhesive, the light transmittance of the second shielding layer 123 may be different from that of the first shielding layer 122 .

[0099] Specifically, the light transmittance of the second shielding layer 123 is lower than the light transmittance of the first shielding layer 122 .

[0100] The light transmittance of the second shielding layer 123 is set to be lower than the light transmittance of the first shielding layer 122, that is, the black concentration of the second shielding layer 123 is set to be higher than the black concentration of the first shielding layer 122, so that the shielding effect of the second shielding layer 123 is better, and since the frame area BB does not perform luminous display, the shielding of the second shielding layer 123 will not affect the display effect of the display module.

[0101] In some embodiments, Figure 5 and Figure 6 As shown, the optical structure layer 12 may further include a light absorbing layer 124 .

[0102] The light absorbing layer 124 is located on the side of the encapsulation layer 121 away from the substrate 10, and the orthographic projection of the light absorbing layer 124 on the substrate 10 covers the substrate 10. The light absorbing layer 124 can absorb ambient light and reduce reflected light. In addition, the orthographic projection of the light absorbing layer 124 on the substrate 10 covers the orthographic projection of the encapsulation layer 121 on the substrate 10, the orthographic projection of the first shielding layer 122 on the substrate 10, and the orthographic projection of the second shielding layer 123 on the substrate 10. Therefore, the light absorbing layer 124 can play a leveling role and improve the flatness of the surface of the side of the light absorbing layer 124 away from the substrate 10.

[0103] During implementation, the material of the light absorbing layer 124 may also be black optical glue, so as to ensure the light absorbing property of the light absorbing layer 124 and improve the contrast of the display module.

[0104] In addition, the light absorbing layer 124 and the first shielding layer 12 are both made of black optical glue, and the intersection of the light absorbing layer 124 and the shielding portion 12A can be used to deepen the texture effect when the display module is not displayed, thereby further improving the integration of the display module with the surrounding environment.

[0105] At the same time, in order to ensure the light emitting effect of the display module, the light transmittance of the light absorbing layer 124 may be greater than the light transmittance of the first shielding layer 12 .

[0106] Specifically, the black concentration of the light absorbing layer 124 may be smaller than the black concentration of the first shielding layer 12 , thereby reducing the interference of stray light while ensuring the light extraction rate.

[0107] In some embodiments, in order to further focus the light and improve the brightness of the light, Figure 7 , Figure 8 Fig. 9 and Fig.10 As shown, a surface of the light absorbing layer 124 facing away from the substrate 10 may be provided with a plurality of spaced-apart micro lenses.

[0108] Specifically, the surface morphology of the light absorbing layer 124 facing away from the substrate 10 can be set to a microlens shape, so as to utilize the function of the microlens to converge light, so that the light emitted by the light emitting device Q can be converged by the microlens when passing through the light absorbing layer 124, thereby increasing the light in the light emitting direction and improving the brightness.

[0109] During implementation, the material of the micro lens can be the same as that of the light absorbing layer 124 . For example, the material of the micro lens and the light absorbing layer 124 is black optical glue with the same black concentration.

[0110] In practical applications, the microlens can be integrated with the light absorbing layer 124 to simplify the preparation process and improve product preparation efficiency.

[0111] In some embodiments, Figure 7 and Figure 8 As shown, the microlens may include a plano-convex lens S1; a plurality of plano-convex lenses S1 correspond one-to-one to a plurality of light-emitting devices Q; and the orthographic projection of the plano-convex lens S1 on the substrate 10 covers the orthographic projection of the corresponding light-emitting device Q on the substrate 10 .

[0112] The emitted light W of the light emitting device Q passes through the light absorbing layer 124 and can be converged by the plano-convex lens S1, thereby achieving the effect of improving the light extraction efficiency.

[0113] During implementation, the orthographic projection of the plano-convex lens S1 on the substrate 10 coincides with the orthographic projection of the corresponding light emitting device Q on the substrate 10. In this way, the outgoing light W can be converged as much as possible to enhance the display effect of the display module.

[0114] In some other embodiments, such as Fig. 9 and Fig.10 As shown, the microlens may also include a plano-concave lens S2; a plurality of plano-concave lenses S2 correspond one to one to a plurality of shielding portions 12A; and the orthographic projection of the shielding portion 12A on the substrate 10 covers the orthographic projection of the corresponding plano-concave lens S2 on the substrate 10 .

[0115] The emitted light W of the light emitting device Q passes through the light absorbing layer 124 and can be converged by the plano-concave lens S2, thereby achieving the effect of improving the light extraction efficiency.

[0116] Specifically, the orthographic projection of the plano-concave lens S2 on the substrate 10 coincides with the orthographic projection of the corresponding shielding portion 12A on the substrate 10 , so that more large-angle outgoing light rays W can be gathered to enhance the display effect of the display module.

[0117] It should be noted that, in order to ensure the focusing effect of the microlens, when the microlens is a plano-convex lens, the light absorbing layer 124 can be made of a high-refractive material. The high-refractive material can be set according to actual needs, for example, a black optical glue with a high refractive index, etc., which is not specifically limited here. Similarly, when the microlens is a plano-concave lens, the light absorbing layer 124 can be made of a low-refractive index material. The low-refractive index material can be set according to actual needs, for example, a black optical glue with a low refractive index, etc., which is not specifically limited here.

[0118] In some embodiments, the material of at least one of the first shielding layer 122 , the second shielding layer 123 , and the light absorbing layer 124 includes: a photochromic material and / or a thermochromic material.

[0119] Specifically, at least one of the first shielding layer 122 , the second shielding layer 123 and the light absorbing layer 124 may be made of a photochromic material, which may cause the film layer having the material to change color after absorbing ultraviolet light, thereby realizing intelligent color change of the display module.

[0120] Similarly, at least one of the first shielding layer 122, the second shielding layer 123 and the light absorbing layer 124 is made of a thermochromic material, which allows the film layer having the material to absorb heat and change color when the display module generates heat, thereby achieving intelligent color change and dissipating heat for the screen.

[0121] In some embodiments, Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 As shown, the display module may further include a hardening coating 17 ; the hardening coating 17 is located on the side of the light absorbing layer 124 away from the substrate 10 ; the orthographic projection of the hardening coating 17 on the substrate 10 covers the substrate 10 .

[0122] In this way, the hardened coating 17 can be used to replace the cover plate to protect the screen body, improve the surface hardness of the display module, and enhance the wear resistance and damage resistance.

[0123] Moreover, in an embodiment of the present application, an optical structure layer 12 is provided in the display module, and a hardened coating layer 17 is coated on the side of the optical structure layer 12 facing away from the substrate 10. This allows the display module to eliminate the need for a polarizer, an optical adhesive layer, and a cover plate, thereby further reducing the thickness of the display module and making the display module thinner and lighter, while simplifying the preparation process and improving the preparation efficiency.

[0124] Of course, in other embodiments, other film layers may be provided as needed. For example, when touch control is required, a touch function layer may be provided on the side of the packaging layer away from the substrate to realize the touch function of the display panel, etc., which will not be elaborated here.

[0125] As an optional implementation of the content disclosed in this application, the embodiment of this application further provides a display device, which includes: a display module provided in any of the above embodiments. Fig.12 As shown, Fig.12 This is a schematic diagram of the structure of a display device provided in one embodiment of the present application. The display device may be a smart phone, a tablet computer, a digital camera, etc., which will not be described in detail here.

[0126] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0127] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
