[0026] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0028] Flexible organic light-emitting displays are increasingly used in mobile phones due to their light, thin and bendable properties, and are gradually expanding to more electronic devices such as laptops and tablets.

[0029] A schematic diagram of stacking an organic light-emitting display screen in the related art is shown in FIG. Figure 1As shown, from top to bottom, it includes a glass cover 100, an optical double-sided adhesive 200, a polarizer 300, an organic light-emitting display 400, a back panel 500, a grid adhesive 600, a foam protective layer 700, a double-sided adhesive 800, and a copper foil layer 900. However, when integrating such a display into a device, a method is usually adopted in which a pull-out double-sided adhesive 1000 of a specific shape (such as a "mouth" shape or a "double vertical bar" shape) is pasted on the back of the screen, and then attached to the inside of the back shell of the electronic device. In this process, due to the hardness of the pull-out double-sided adhesive 1000, it will transfer stress to the back of the flexible organic light-emitting display when it is subjected to the pressure of the back shell. Considering that the substrate of the flexible organic light-emitting display is mostly polyimide (PI), and the supporting material of the back panel 500 is often cycloolefin polymer (COP), both of which are highly flexible materials, which makes them easy to deform when receiving external stress, thereby appearing as irreversible marks on the front of the screen, such as Figure 2 As shown, the user's visual experience and the overall aesthetics of the product are seriously affected, and such damage is difficult to repair.

[0030] In view of the above-mentioned technical problems, the present application provides a display module, which aims to reduce the visibility of marks caused by deformation on the display surface, so as to optimize the viewing experience and improve user satisfaction.

[0031] like Figure 3 As shown, an embodiment of the present application provides a display module, which may include: a first layer 1, a second layer 2 and a third layer 3 stacked in sequence; the first layer 1 may be a flexible medium, and the first layer 1 is used for luminous imaging; the second layer 2 is used to reduce the amount of first light incident on the second layer 2 through the first layer 1, and reduce the reflectivity of the first light; the third layer 3 is used to reduce the reflectivity of the first light.

[0032] Display modules can be applied to screens of various electronic devices, such as smartphones, tablet computers, and TVs.

[0033] The first light may be the light initially irradiated onto the surface of the first layer 1. The first layer 1, as the base layer that is most directly in contact with the light-emitting part, may be made of a high-performance flexible medium, which is mainly responsible for carrying and transmitting light signals to realize image display. The first layer 1 may be a flexible organic light-emitting display screen, which may maintain sufficient flexibility to adapt to various deformation requirements, such as bending or folding, without negatively affecting the display quality.

[0034] The second layer 2 can be arranged next to the first layer 1, which can reduce the amount of light transmitted from the first layer 1 and effectively reduce the reflectivity of these lights. The second layer 2 can be realized by integrating a proprietary optical film or using a material with light-absorbing properties. For example, a resin layer doped with a special dye or pigment can be selected to directly absorb unnecessary light and reduce its penetration into the third layer 3; or an AR coating, that is, an anti-reflection film or anti-reflection film, can be selected. The principle of AR coating is based on the interference effect of light. Through the reflection and refraction of light at the interface of different media, multi-layer materials are designed (which may include alternating layers of high and low refractive index materials) and then deposited at a specific thickness, so that the reflected light waves interfere with each other and cancel each other out, ultimately achieving a reduction in the total amount of reflected light. AR coatings are widely used in eyeglass lenses, camera lenses, displays, mobile phone screens, sunglasses, etc.

[0035] When the internal structure of the display module, especially the back, is subjected to pressure and produces slight deformation during assembly or use, these deformations may appear as subtle traces on the first layer 1 (display imaging layer) through the light reflection effect, thereby affecting the purity and display effect of the screen. By placing the second layer 2 behind the first layer 1, the amount of light penetrating the first layer 1 is effectively reduced, thereby directly reducing the intensity of light reaching the back of the display module. And the second layer 2 can reduce the reflection and refraction opportunities of the first light between the first layer 1 and the second layer 2 by reducing the reflectivity of the light, and effectively control the propagation path of the first light inside the display module. Therefore, when the back of the display module undergoes slight deformation, the light amount and reflection are reduced by the second layer 2, so that the light that the first light finally reflects to the human eye is significantly reduced. Thereby indirectly reducing the visual traces caused by deformation, even if deformation occurs, its impact on the appearance display becomes imperceptible, thereby maintaining the high quality and purity of the screen display and improving the user's visual experience.

[0036] The third layer 3 is located below the second layer 2, and can further suppress the reflection of the light that has passed through the second layer 2 and has been subjected to a reduced reflectivity. The third layer 3 may include an anti-reflective coating or a microstructure design. For example, a nano-level texture may be formed on the surface of the third layer 3, and these tiny concave-convex structures may be arranged in a specific pattern, such as a pyramid, a cylinder, or other geometric shapes, to change the light path and reduce vertical reflection; or the third layer 3 may be made of a gradient refractive index material, which uses a material with a gradual refractive index design that gradually changes from the surface to the inside, and can continuously change the refraction angle of the light to effectively suppress reflection.

[0037] The third layer 3 can intervene again on the remaining light after penetrating the second layer 2, further reducing the possibility of it being reflected back to the first layer 1. After the first light is initially processed by the second layer 2, it is already weakened when it reaches the third layer 3. The intervention of the third layer 3 further ensures that these lights are effectively scattered to reduce the direct reflection of some lights back to the second layer 2. For the small amount of light that still attempts to be reflected back to the second layer 2 after being scattered by the third layer 3, the second layer 2 further reduces the amount of light reaching the first layer 1 by absorbing and further reducing the reflection function, thereby significantly reducing the amount of light reaching the observer's eyes. By reducing these undesirable light feedbacks, even if deformation exists, it will not appear blurred or have abnormal spots due to the messy light caused by internal reflection, thereby effectively avoiding these deformations from producing obvious visual traces on the display screen, improving the overall display purity and user visual experience.

[0038] The display module provided by the embodiment of the present application performs the first absorption and reflection reduction treatment on the light that has penetrated the first layer 1 through the second layer 2. The proportion of light directly reflected back to the first layer 1 is reduced, and the light processed by the second layer 2 continues to penetrate into the third layer 3. The third layer 3 can effectively disperse the light, further reducing the probability of light reflecting along the original path. Finally, the light processed by the second layer 2 and the third layer 3 significantly reduces the amount of light that still attempts to reflect back to the first layer 1 and reflects back to the viewer, thereby avoiding the visibility of the imprint that may be revealed due to the deformation of the internal structure.

[0039] In some embodiments, the second layer 2 can be constructed as a color layer; wherein the first light after reflection processing by the third layer 3 is the second light, and the color layer is also used to reduce the light amount of the second light.

[0040] The second layer 2 can be designed as a color layer, and can use special optical materials or color filter films, and select low-saturation colors such as dark gray, navy blue, dark brown, etc. The color layer can absorb light of specific wavelengths through its specific pigments, effectively reducing unnecessary color reflections, thereby reducing the intensity and reflectivity of light passing through the first layer 1. After the initial reflection reduction of the color layer, the first light continues to penetrate to the third layer 3, and after another reflection reduction treatment, the second light is obtained. At this time, the amount of light of the second light is significantly reduced compared to the first light. The second light is reflected back to the color layer and intervened by its pigment again, achieving a further reduction in the amount of light. It can be achieved that the light projected to the first layer 1 has extremely low intensity when reflected to the observer's eyes after multiple adjustments, significantly reducing the visibility of screen deformation marks that may be caused by assembly stress.

[0041] The color layer is designed to match the image output of the first layer 1 flexible organic light-emitting display. The filter characteristics of the color layer can accurately correspond to the wavelength of light emitted by the pixels of the flexible organic light-emitting display. By accurately analyzing the spectrum emitted by each sub-pixel (red, green, and blue) of the flexible organic light-emitting display, the filter materials of the color layer are designed to ensure that these materials can allow light of specific wavelengths to pass smoothly while blocking or attenuating unwanted wavelengths, thereby reducing color distortion.

[0042] In some embodiments, Figure 4 As shown, the color layer can be black.

[0043] The color layer can be made of high-purity black material, such as a special optical coating containing carbon black or other highly efficient light absorbers. Since black can absorb all light in the visible spectrum, when used as a color layer, it can minimize the light transmitted through the first layer 1 and its subsequent reflection, and almost no additional color deviation is generated, ensuring efficient light management. This effectively covers the internal structure marks that may be caused by assembly or deformation, maintains the neatness and professionalism of the screen appearance, and improves the overall product aesthetics.

[0044] In some embodiments, the surface of the second layer 2 may have a concavo-convex structure.

[0045] The second layer 2 may be a film layer with a concave-convex structure on the surface. The concave-convex structure on the surface of the second layer 2 may be made by a patterning process at the micrometer or nanometer level. These structures may be randomly distributed or regularly arranged, such as a microlens array, a pyramid structure, or a microhole array. The concave-convex structure can physically scatter light, change the light path, reduce direct reflection, and guide the light to be evenly distributed, increase the chances of light scattering and absorption inside the display module, and thus further reduce the reflectivity. The concave-convex structure can distract the attention of the eyes from the details of the internal structure of the screen to a certain extent, further cover up the minor defects that may be caused by deformation, and enhance the overall aesthetics of the display panel.

[0046] In some embodiments, the second layer 2 may be configured as a color layer having a concave-convex structure on its surface.

[0047] The second layer 2 can be made of a material containing a specific color component, and a micron or nanometer-level concave-convex structure can be formed on its surface. The color layer and the surface concave-convex structure can work together to absorb, scatter and transmit light to achieve the best visual effect. For example, the black layer combined with the microstructure can absorb light more effectively and reduce reflection.

[0048] The second layer 2 not only serves as a color layer to adjust and absorb light of a specific wavelength, but also has a concave-convex structure on its surface, which can more effectively scatter incident light and reduce specular reflection, thereby further enhancing light management and optimizing visual effects.

[0049] In some embodiments, Figure 4 As shown, the third layer 3 may be a moth-eye film structure.

[0050] The moth-eye film structure can be composed of a large number of tiny hexagonal or circular protrusions, each with a diameter of about hundreds of nanometers, which are closely arranged to form a honeycomb-like arrangement. The display module may include a fourth layer 4 for supporting the first layer 1 of the flexible organic light-emitting display screen. The fourth layer 4 may be a backplane COP layer (Cyclo Olefin Polymer). These tiny three-dimensional structures can be made on the surface of the fourth layer 4 facing the first layer 1 by nanoimprinting or roller imprinting.

[0051] Each microstructure of the moth-eye film structure can scatter the incident light, changing the incident angle of the light, making it impossible to form a strong reflection at the interface, but instead spreading it out in a diffuse reflection manner, greatly reducing the reflectivity of the surface.

[0052] When the display module is integrated into the device, considering the space limitation and visual optimization requirements, the first layer 1 to the third layer 3 need to be made thinner and lighter. In the case of thinness, although the second layer 2 can use a black color layer to absorb part of the light, it is still inevitable that a small amount of light will penetrate into the third layer 3. At this time, the moth-eye film structure of the third layer 3 can further reduce the reflection of the penetrating light, ensuring that the intensity of light that finally reaches the observer's eyes is minimized. By reducing the interference of reflected light, the problem of screen deformation marks that may be caused by assembly pressure is effectively alleviated, so that the visual appearance of these marks is greatly suppressed.

[0053] In some embodiments, there may be a plurality of third layers 3 , and the plurality of third layers 3 are stacked in sequence, and the densities of the plurality of third layers 3 are different.

[0054] The different densities of multiple third layers 3 mean that light will encounter different levels of scattering and absorption when penetrating. By using transparent dielectric materials with different refractive indices to form multiple layers of superposition, the reflected light of specific wavelengths cancels each other out through the interference effect of light. For example, the initial looser layer can be responsible for widely scattering most of the incident light, while the subsequent high-density layer can perform more in-depth light regulation, capturing and dispersing those lights that have not been fully processed by the previous layers, thereby building a progressive layer-by-layer reflection reduction mechanism. The third layer 3 of different densities can manage light of different wavelengths more carefully. After progressive scattering and absorption layer by layer, the light finally achieves an excellent reflection reduction effect, significantly reducing the amount of light reflection that finally reaches the observer's eyes.

[0055] In some embodiments, Figure 5 and Figure 6 As shown, the display module may further include: a metal layer 5 , which is arranged on a side of the third layer 3 facing away from the second layer 2 , and is used to support the third layer 3 .

[0056] In the related art, a COP layer used as a backplane is arranged behind the third layer 3 in the display module as the fourth layer 4, but the COP material is prone to deformation due to its flexible characteristics. To address this problem, the display module provided by the present application uses a metal layer as a reinforcement measure to integrate the display module into the electronic device, aiming to reduce the deformation of the COP layer. The metal layer 5 such as aluminum, stainless steel or magnesium alloy is precisely processed into a thin sheet form to ensure that it has sufficient support strength without causing too much burden on the thin and light characteristics of the display module.

[0057] The metal layer 5 can be closely connected to the fourth layer 4 by adhesive, welding or physical clamping to ensure seamless fit between the two, enhance the stability and rigidity of the overall structure, and effectively improve the resistance to unexpected impact and deformation. This significantly reduces the deformation and crease problems that may occur in the fourth layer 4 of the COP backplane during assembly and daily use, thereby maintaining the flatness of the display module and long-term visual effects.

[0058] In some embodiments, the display module may further include: a heat dissipation layer 6 , which is disposed on the side of the metal layer 5 facing the third layer 3 , or on the side facing away from the third layer 3 ; the heat dissipation layer 6 is used to dissipate heat from the metal layer 5 .

[0059] The heat dissipation layer 6 can be located on one side of the metal layer 5 (towards the third layer 3 or away from the third layer 3) to enhance the heat dissipation effect on the metal layer 5. The heat dissipation layer 6 can be made of high thermal conductivity materials, such as graphene, copper foil, heat pipe or phase change material, etc., which have excellent thermal conductivity. The heat dissipation layer 6 can be designed as a film, a multi-layer composite structure or a complex form containing microchannels to meet different heat dissipation requirements and space limitations.

[0060] like Figure 5 As shown, when the heat dissipation layer 6 is installed close to the metal layer 5 and facing the third layer 3, a graphite heat sink 601 can be used. In order to maintain the integrity of the graphite heat sink 601 and prevent dispersion, a PI sheet 602 (polyimide) can be embedded between the graphite heat sink 601 and the stainless steel metal layer 5 as reinforcement. Figure 6 As shown, if the heat dissipation layer 6 is placed at the end of the metal layer 5 away from the third layer 3, the graphite heat sink 601 can be covered with a Mylar protective sheet 603, which also ensures the stability of the graphite heat sink 601 and prevents it from being scattered. By adding the heat dissipation layer 6, even if the metal layer 5 is made of thicker stainless steel, it can still achieve an ideal heat dissipation effect, ensure that the heat energy of the display module is quickly discharged, and maintain the stability of the system operation.

[0061] In some embodiments, Figure 5 and Figure 6 As shown, the display module may further include a buffer layer 7, which may be disposed between the fourth layer 4 (COP backplane) and the metal layer 5, to effectively alleviate the deformation problem of the fourth layer 4. The buffer layer 7 may be a soft material or a gel-like material with high elasticity and low creep properties, such as a foam protective layer in the related art, to enhance the ability to absorb and disperse mechanical stress, and to use adhesives such as grid glue and double-sided adhesives so that the buffer layer 7 can be firmly attached to both sides of the fourth layer 4 and the metal layer 5, ensuring a tight and stable connection between the structures. The buffer layer 7 can significantly reduce the pressure applied to the fourth layer 4 by external forces, effectively suppress the appearance of surface creases caused by deformation, thereby maintaining the flatness and long-term visual effects of the display module.

[0062] The present application also provides a display screen, such as Figures 5 to 7 As shown, it may include: a display module 10, the display module 10 includes: a first layer 1, a second layer 2 and a third layer 3 stacked in sequence; the first layer 1 is a flexible medium, and the first layer 1 is used for luminous imaging; the second layer 2 is used to reduce the amount of first light incident on the second layer 2 through the first layer 1, and reduce the reflectivity of the first light; the third layer 3 is used to reduce the reflectivity of the first light; a display driving component 20, and the display driving component 20 is electrically connected to the first layer 1.

[0063] The core of the display screen is the display module 10. The first layer 1 in the display module 10 can be made of a flexible medium, which is a key layer for display imaging. It is responsible for generating and transmitting light signals to ensure the output of images and has the characteristics of adapting to bending or folding. The second layer 2 is located below the first layer 1 and is used to reduce the brightness of light passing through the first layer 1. It may use translucent or light-absorbing materials to reduce the reflectivity of light. The third layer 3 is located below the second layer 2 and can further reduce the reflectivity of light. Anti-reflective materials or structures (such as moth eye films) can be used to reduce ambient light interference with extremely low reflectivity and enhance the visual experience.

[0064] The display driving component 20 of the display module 10 can integrate a rigid driving circuit board 21, a flexible driving circuit board 22 and a driving chip 23, which are respectively connected to the first layer 1, and can accurately control the generation and instant refresh of the image to ensure smooth display content and quick response.

[0065] The second layer 2 and the third layer 3 can effectively reduce light brightness and reflection, significantly reduce the visibility of display screen deformation marks that may be caused by assembly stress, and improve the stability and visual purity of the overall structure.

[0066] In some embodiments, the display screen may further include a cover plate 30 , which is disposed on a side of the first layer 1 facing away from the second layer 2 through a first adhesive layer 40 .

[0067] The cover plate 30 covers the other side of the first layer 1, that is, the side away from the second layer 2, and is firmly bonded by the first adhesive layer 40. The cover plate 30 can be a transparent hard material, such as glass or reinforced plastic, to provide protection and surface smoothness. The first adhesive layer 40 can be an optical double-sided adhesive to ensure the sealing and firm connection between the cover plate 30 and the first layer 1, while taking into account optical transparency and durability. Among them, a polarizer can be arranged between the first layer 1 and the first adhesive layer 40. The polarizer is an optical film that contains a large number of parallel microstructures inside, which only allows light in a specific direction to pass through, effectively inhibiting the penetration of light at other angles, significantly improving the contrast of the display image, making the colors more vivid and full, especially in high-brightness environments, can reduce the interference of external light on the display effect.

[0068] The present application also provides an electronic device, such as Figure 7As shown, it may include: a display screen, the display screen includes a display module 10, the display module 10 includes: a first layer 1, a second layer 2 and a third layer 3 stacked in sequence; the first layer 1 is a flexible medium, and the first layer 1 is used for luminous imaging; the second layer 2 is used to reduce the amount of first light incident on the second layer 2 through the first layer, and reduce the reflectivity of the first light; the third layer 3 is used to reduce the reflectivity of the first light; a display driving component 20, the display driving component 20 is electrically connected to the first layer 1; and, a shell 50, the shell 50 has a cavity, the display screen is arranged in the cavity, the back plate of the shell 50 is connected to the display screen through a second adhesive layer 60, and the second adhesive layer 60 can apply a supporting force to a part of the display screen.

[0069] The electronic device may be a smart phone, a tablet computer, a television, or other device having the display screen provided by the above embodiments.

[0070] The electronic device may further include a housing 50, which is composed of a frame and a back panel. The frame surrounds the edge of the back panel to form a stable cavity, providing installation space and physical protection for the display screen. The back panel and the display screen may be connected by an easy-to-pull double-sided adhesive tape as the second adhesive layer 60. The second adhesive layer 60 may be designed in a "mouth" shape or a "double vertical bar" shape and pre-attached to the back panel, so that it is easy to separate when the display screen needs to be repaired or replaced without damaging the display screen or the back panel, greatly improving the maintenance convenience and sustainability of the device. The easy-to-pull double-sided adhesive tape may be an easy-to-pull adhesive tape with a grid in the middle, so that when stress is transmitted to the easy-to-pull adhesive tape, it is not easy to be transmitted to the back of the display screen through the easy-to-pull adhesive tape.

[0071] Since the second adhesive layer 60 is only partially connected to the display screen on the back plate, the second adhesive layer 60 may exert a force on the back of the display screen, causing the back material of the display screen to deform, resulting in creases, which affects the visual effect. The electronic device provided by the embodiment of the present application realizes efficient luminous imaging through the display module 10 in its display screen, including the flexible medium layer of the first layer 1, and the second layer 2 and the third layer 3 respectively finely control the brightness and reflectivity of the light, which significantly reduces the visibility of the deformation marks of the display screen that may be caused by assembly stress, and improves the stability and visual purity of the overall structure.

[0072] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
