Description

A display module and electronic device

[0001] This application claims priority to Chinese Patent Application No. 202411016772.4, filed with the State Intellectual Property Office of China on July 26, 2024, entitled "A Display Module and Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of electronic equipment technology, and in particular to a display module and electronic equipment. Background Technology

[0003] Electronic device screens are prone to display problems such as glare and flickering, which affect the display effect and are detrimental to the user's viewing experience.

[0004] Application content

[0005] The purpose of this application is to provide a display module and electronic device to solve the technical problems existing in the prior art, and the processing difficulty is relatively low.

[0006] In a first aspect, embodiments of this application provide a display module, including: a cover plate and a display panel, the cover plate having a first functional layer, the first functional layer including a plurality of first microstructures; the display panel being connected to a side of the cover plate opposite to the first functional layer; wherein, the display panel includes a display body, a second functional layer being disposed between the display body and the cover plate, the second functional layer including a plurality of second microstructures, the radial dimension of the second microstructures being smaller than the radial dimension of the first microstructures.

[0007] When external light shines on the cover plate, the light is diffused on the first functional layer, preventing the user's eyes from receiving glare from specular reflections. Therefore, the first functional layer effectively reduces glare, minimizing the interference of ambient light on the display module's performance and improving the user's viewing experience. The display itself emits light. Since the second functional layer is located between the cover plate and the display itself, the light emitted from the display passes through the second functional layer first and then through the first functional layer before being emitted. The light is first deflected at the second microstructures and then at the first microstructure. Because the second functional layer has multiple microstructures with small radial dimensions, it can diffuse the light. Specifically, under the influence of these multiple microstructures, the light passing through the second functional layer is deflected in multiple directions and dispersed, resulting in reduced light intensity and brightness. Because the brightness of the light decreases, even if different light rays mix and overlap when passing through the first microstructure, they will not form bright flashes. As a result, there will be no uneven brightness in the display of the display module, thus improving the user's viewing experience.

[0008] The first and second functional layers are located on different carriers, meaning that they are not entirely formed on the cover plate. This prevents the processing of the first and second functional layers from interfering with each other, thereby reducing the processing difficulty of the first and second functional layers, ensuring the processing quality of each layer, and improving the stability of the first and second microstructures. This enhances the effectiveness of each layer. Furthermore, the relatively low processing difficulty makes it easier to implement, which is beneficial for the mass production of the display module.

[0009] In one possible implementation, the radial dimension D1 of the first microstructure is 15 μm to 40 μm, and the haze of the first functional layer is 20% to 40%.

[0010] By designing the radial dimensions of the first microstructure and the haze of the first functional layer within a reasonable range, the anti-glare effect of the first functional layer is improved, thereby enhancing the display effect of the display module and improving the user's viewing experience.

[0011] In one possible implementation, the cover plate has a first surface, and the first microstructure is located on the first surface; wherein the first microstructure protrudes toward a side opposite to the display panel, or the first microstructure is recessed toward a side closer to the display panel.

[0012] Specifically, a raised first microstructure can be formed on the first surface using a spraying process, or a recessed first microstructure can be formed on the first surface using an etching process. In actual production, the processing technology for the first functional layer can be selected according to actual usage needs; either spraying or etching can be used, thus improving the flexibility of the first functional layer processing. The recessed first microstructure helps reduce the thickness of the cover plate, meaning the first microstructure does not require additional space in the thickness direction of the display module, making the overall display module thinner and lighter.

[0013] In one possible implementation, the display body includes a plurality of pixel units, each pixel unit including a sub-pixel; along the thickness direction of the display module, the projected area of ​​one of the second microstructures is smaller than the projected area of ​​one of the sub-pixels.

[0014] When the radial dimension of the second microstructure is smaller than the radial dimension of the sub-pixel, the light from the sub-pixel can be fully diffused in the second functional layer, giving the second functional layer an ideal anti-flash point effect.

[0015] In one possible implementation, along the thickness direction of the display module, the projections of a plurality of the second microstructures are located within the projection of the same sub-pixel.

[0016] When multiple projections of second microstructures fall within a sub-pixel, the light emitted from that sub-pixel can be deflected by these microstructures, causing the light to diverge in multiple directions. This disperses a concentrated beam of light into multiple beams, effectively reducing brightness. This design improves the anti-flicker effect of the second functional layer, ensuring that the second functional layer can fully diverge the light emitted from the sub-pixels, thereby reducing the possibility of flickering issues in the display module.

[0017] In one possible implementation, the radial dimension D2 of the second microstructure is 1µm to 10µm, and the haze of the second functional layer is 1% to 15%.

[0018] By designing the radial dimensions of the second microstructure and the haze of the second functional layer within a reasonable range, the second functional layer can effectively diffuse light, thereby improving the anti-flicker effect of the second functional layer and thus enhancing the display effect of the display module and improving the user's viewing experience.

[0019] In one possible implementation, the display module includes a substrate connected between the cover plate and the display panel; the second functional layer is disposed on the surface of the substrate facing the cover plate, or the second functional layer is disposed on the surface of the substrate facing the display panel.

[0020] In this design, the substrate can be considered as the carrier of the second functional layer. The substrate material can be the same as or different from the cover plate. During the production of the display module, the cover plate and the substrate can be processed separately first. Then, the first functional layer can be processed on the cover plate, and the second functional layer can be processed on the substrate. Finally, the cover plate, the cover plate, and the display panel are assembled together. This ensures that the processing of the first functional layer and the processing of the second functional layer do not interfere with each other. This design and processing method is simpler and easier to implement, which is beneficial for the mass production of display modules.

[0021] In one possible implementation, the substrate is a glass plate; the second microstructure protrudes or is recessed relative to the surface of the glass plate.

[0022] The glass plate provides a stable and reliable carrier for the second functional layer, thereby improving its stability and reliability. This, in turn, enhances the display effect of the display module and reduces the likelihood of the aforementioned flashpoint issues. Simultaneously, the glass plate protects the display panel, ensuring its normal operation. Furthermore, due to its high strength, the glass plate increases the overall strength of the display module, thus improving its structural stability and extending its lifespan.

[0023] In one possible implementation, the substrate is a plastic sheet; the second microstructure protrudes or recesses relative to the surface of the plastic sheet.

[0024] The relatively stable structure of the plastic sheet provides a stable and reliable carrier for the second functional layer, which is beneficial for improving the stability and reliability of the second functional layer. This, in turn, enhances the display effect of the display module and reduces the possibility of the aforementioned flashpoint problem. Simultaneously, the plastic sheet is lightweight, reducing the overall weight of the display module. Furthermore, the plastic sheet is easy to process and mold, reducing the production difficulty of the display module and facilitating mass production. In addition, the plastic sheet also protects the display panel, ensuring its normal operation. The second functional layer can be formed on the surface of the plastic sheet using a spray coating process. Alternatively, due to the low hardness of plastic, an imprinting process can be used to form the second functional layer; for example, rollers or similar devices can be used to press the second microstructure onto the surface of the plastic sheet. The imprinting process is relatively simple, reducing the processing difficulty of the second functional layer and facilitating the mass production of the entire display module.

[0025] In one possible implementation, the display panel includes a polarizer connected to the display body on the side near the cover plate; a protective film is disposed on the side of the polarizer facing the cover plate; and a second functional layer is disposed on the protective film.

[0026] The protective film has a second functional layer, which means that the protective film can serve as a carrier for the second functional layer. This design eliminates the need for spraying, etching, or imprinting on the internal structure of the polarizer. In other words, the second functional layer does not affect the internal structure of the polarizer, thus improving the stability and reliability of the polarizer and helping to extend its service life.

[0027] In one possible implementation, the display panel includes a polarizer connected to the display body on the side near the cover plate; the second functional layer is disposed on the polarizer.

[0028] The carrier for the first functional layer can be a cover plate, and the carrier for the second functional layer can be a polarizer in the display panel. In other words, the first and second functional layers are set on different carriers, so that the processing of the first functional layer and the processing of the second functional layer will not affect each other, reducing the processing difficulty of the first and second functional layers and facilitating the mass production of the display module.

[0029] In one possible implementation, the polarizer includes a polarizing layer and a first protective layer located on the side of the polarizing layer near the cover plate; the second functional layer is disposed on the surface of the first protective layer, wherein the second microstructure protrudes or is recessed relative to the surface of the first protective layer.

[0030] The polarizing layer can be a specially treated polyvinyl alcohol layer, primarily functioning to polarize light. This means the polarizing layer uses the polarization characteristics of light to control the light emitted from the display module, enabling the display module to function properly. The first protective layer can be a TAC layer or a PET layer, providing support and protection for the polarizer, thus extending its lifespan. Placing the second functional layer on top of the first protective layer reduces the possibility of it affecting the polarizing layer. This eliminates the need for spraying, etching, or imprinting on the polarizing layer, ensuring its polarization effect and improving the reliability of the polarizer.

[0031] In one possible implementation, the polarizer includes a polarizing layer and a first protective layer located on the side of the polarizing layer near the cover plate; the second functional layer is disposed within the first protective layer, wherein the second microstructure is transparent particles.

[0032] The second microstructure can also be a transparent particle that can deflect light. This transparent particle can be made of plastic or other transparent materials. It can be incorporated into the first protective layer during its manufacturing process; in other words, the transparent particle and the first protective layer are integral. This design eliminates the need for etching, spraying, or other processes on the first protective layer, simplifying the production process of the polarizer and the entire display module, thus facilitating mass production of the display module.

[0033] In one possible implementation, the polarizer includes a polarizing layer and a second protective layer located on the side of the polarizing layer near the display body; the second functional layer is disposed on the surface of the second protective layer, wherein the second microstructure protrudes or is recessed relative to the surface of the second protective layer.

[0034] The principle of setting the second functional layer on the second protective layer is the same as that of setting the second functional layer on the first protective layer as described above, and will not be repeated here.

[0035] In one possible implementation, the polarizer includes a polarizing layer and a second protective layer located on the side of the polarizing layer near the display body; the second functional layer is disposed within the second protective layer, wherein the second microstructure is transparent particles.

[0036] The principle of setting the second functional layer with transparent particles on the second protective layer is the same as that of setting the second functional layer with transparent particles on the first protective layer as described above, and will not be repeated here.

[0037] In one possible implementation, the cover plate and the display panel are connected by an adhesive; the second functional layer is located within the adhesive, wherein the second microstructure is transparent particles.

[0038] The second microstructure can be transparent particles, which can be placed in the colloid between the cover plate and the display panel. In other words, the colloid and the second functional layer become an integral whole. This design eliminates the need for etching, spraying, or other processes on the substrate or polarizer, simplifying the entire display module production process and facilitating mass production of the display module.

[0039] In one possible implementation, the display panel includes a polarizer; the polarizer includes a polarizing layer and a first protective layer located on the side of the polarizing layer near the cover plate; the polarizing layer and the first protective layer are connected by an adhesive; a second functional layer is located within the adhesive, wherein the second microstructure is transparent particles; or, the polarizer includes a polarizing layer and a second protective layer located on the side of the polarizing layer near the display body; the polarizing layer and the first protective layer are connected by an adhesive; the second functional layer is located within the adhesive, wherein the second microstructure is transparent particles.

[0040] The second microstructure can be a transparent particle, which can be disposed in the colloid between the polarizing layer and the first protective layer, or it can be disposed in the colloid between the polarizing layer and the second protective layer. In other words, the second functional layer can be formed within the colloid. Specifically, before using the colloid, the aforementioned transparent particles (i.e., the second microstructure) can be mixed into the colloid, making the colloid and the second functional layer a unified whole. This design eliminates the need for etching, spraying, or other processing of the first or second protective layer, simplifying the production process of the polarizer and the entire display module, and facilitating mass production of the display module.

[0041] In one possible implementation, the display module is a flexible display module, wherein the cover plate includes a first folding area, the first folding area being provided with the first functional layer; the display body includes a second folding area, and the second folding area and the second folding area are provided with the second functional layer.

[0042] Flexible display modules undergo repeated unfolding and folding during use, which can easily cause creases to appear on the first folding area of ​​the cover plate. These creases can affect the display effect of the flexible display module. A first functional layer with anti-glare properties is installed on the first folding area. Therefore, external light is diffused at the crease of the first folding area instead of being specularly reflected, thus visually weakening the crease. In other words, users will not see obvious creases on the display module during use. Simultaneously, a second functional layer exists between the first and second folding areas. This second functional layer has an anti-flicker effect, improving the display effect at the crease of the display module. This allows electronic devices to provide users with a clear and comfortable display screen, enhancing the user experience.

[0043] In one possible implementation, the display module is a curved display module, wherein the cover plate includes a first arc-shaped area, the first arc-shaped area being provided with the first functional layer; the display body includes a second arc-shaped area, and the second arc-shaped area and the second arc-shaped area are provided with the second functional layer.

[0044] By setting a second functional layer between the first and second curved areas, the flickering problem caused by the curved display module can be solved, thereby improving the user experience of curved screen phones. At the same time, by setting a second functional layer between the first and second curved areas, the light emitted from the edge of the display body is diffused before passing through the cover plate, reducing the intensity of the light. This makes it so that users will hardly see obvious green light at the edge of the display module, improving the "green edge" problem and enhancing the user experience.

[0045] Secondly, embodiments of this application provide an electronic device, including: a housing and a display module, wherein the display module is mounted on the housing, and the display module is any of the display modules described above.

[0046] By employing the aforementioned display module, electronic devices can provide users with a clear and comfortable display, thereby improving the user experience. Since the display module possesses the aforementioned technical effects, electronic devices equipped with this display module also possess the aforementioned technical effects, which will not be elaborated upon here.

[0070] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0071] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0072] In the description of this application, unless otherwise expressly specified and limited, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance; unless otherwise specified or explained, the term "multiple" refers to two or more; the terms "connected," "fixed," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, an integral connection, or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0073] In this specification, it should be understood that the directional terms such as "upper" and "lower" used in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should also be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0074] With the continuous development of science and technology, electronic devices such as mobile phones, tablets, and laptops are beginning to pursue screen viewing comfort to enhance the user experience. For example, the cover glass of electronic device screens adopts an anti-glare (AG) design, which involves treating the cover glass surface to give it a certain roughness to reduce the possibility of specular reflection, thereby effectively reducing the interference of external ambient light on the screen, improving the screen display effect, and providing users with a good viewing experience. Such screens can be called soft-light screens.

[0075] As the pixel density (PPI) of screens increases, the aforementioned screens with AG design are prone to flickering issues. This can be understood as uneven color or brightness in the displayed image, which affects the screen's display effect and is detrimental to the user's viewing experience.

[0076] Based on this, this application provides a display module that can be used in electronic devices such as tablet computers, laptops, desktop computers, foldable phones, and candybar phones.

[0077] As shown in Figure 1, which is a schematic diagram of a display module 10 according to an embodiment of this application, the display module 10 includes a cover plate 1 and a display panel 3. The cover plate 1 can be made of a high-strength and high-transparency material, such as glass. The cover plate 1 protects the display panel 3, reducing the possibility of scratches or impacts to the display panel 3, thereby extending the service life of the display panel 3 and ensuring its normal use.

[0078] The cover plate 1 is bonded to the display panel 3. For example, the cover plate 1 can be bonded to the display panel 3 using OCA optical adhesive (not shown in the figure). The display panel 3 can be, but is not limited to, an organic light-emitting diode (OLED) display, an active-matrix organic light-emitting diode (AMOLED) display, a mini organic light-emitting diode (MLED) display, a micro organic light-emitting diode (MOLED) display, etc.

[0079] A first functional layer 2 is disposed on the first surface 1a of the cover plate 1 on the side away from the display panel 3, meaning the first functional layer 2 is located on the outer surface of the cover plate 1. The first functional layer 2 includes multiple first microstructures 21, each of which can protrude towards the side away from the display panel 3, thus giving the cover plate 1 an uneven outer surface. When external light shines on the cover plate 1, the light can be diffusely reflected on the first functional layer 2. That is, the light shining on the first functional layer 2 can be irregularly reflected in various directions through the first microstructures 21, so that the user's eyes will not receive glaring specular reflection light. Therefore, the first functional layer 2 has an anti-glare effect, reducing the possibility of external ambient light interfering with the display effect of the display module 10 and improving the user's viewing experience.

[0080] As shown in Figure 2, which is a schematic diagram of the display module 10 in another embodiment of this application, the area enclosed by the dashed lines represents pixel units 311. The display panel 3 has a plurality of pixel units 311 arranged in an array. Each pixel unit 311 may include three sub-pixels 3111. Specifically, the three sub-pixels 3111a, blue sub-pixel 3111b, and red sub-pixel 3111c are green sub-pixels 3111a, blue sub-pixels 3111b, and red sub-pixels 3111c. Understandably, the green sub-pixel 3111a can emit green light to the outside, the blue sub-pixel 3111b can emit blue light to the outside, and the red sub-pixel 3111c can emit red light to the outside. When the light emitted by each of the sub-pixels 3111 passes through the cover plate 1, it will be deflected on the first microstructure 21. When a first microstructure 21 deflects the light of two or more sub-pixels 3111, the light rays can mix and superimpose with each other within the first microstructure 21, resulting in a certain brightness deviation. From the perspective of the display module 10 as a whole, the displayed image will have uneven brightness, that is, the image of the display module 10 has the aforementioned flickering problem.

[0081] The following example illustrates the occurrence of the flashpoint problem.

[0082] Referring again to Figure 2, the first functional layer 2 has a first microstructure 21a. The position of the first microstructure 21a corresponds to the position of a green sub-pixel 3111a and a blue sub-pixel 3111b, which are adjacent to each other. Specifically, along the thickness direction Z of the display module 10, the projection of the first microstructure 21a can overlap with the projections of the green sub-pixel 3111a and the blue sub-pixel 3111b, respectively.

[0083] The light emitted by the green sub-pixel 3111a and the light emitted by the blue sub-pixel 3111b can both pass through the first microstructure 21a and be emitted to the outside. Both the light from the green sub-pixel 3111a and the blue sub-pixel 3111b are deflected on the first microstructure 21a. The deflected light from the green sub-pixel 3111a and the blue sub-pixel 3111b then superimpose and mix together. The brightness of the mixed light is significantly different from the original light; for example, the intensity of the mixed light increases, meaning the brightness increases. Therefore, bright flashes appear on the first microstructure 21a. When the above situation generally occurs between the multiple sub-pixels 3111 in the display module 10 and the multiple first microstructures 21 in the first functional layer 2, the display module 10 exhibits the aforementioned flashing problem. Users will observe uneven brightness on the display screen of the display module 10, thus perceiving the display screen as blurry and unclear.

[0084] A second functional layer can be set in the display module to solve the flickering problem of the display module mentioned above.

[0085] As shown in Figure 3, which is an exploded view of a display module 10 according to an embodiment of this application, the display module 10 includes a cover plate 1 and a display panel 3, with the cover plate 1 connected to the display panel 3. The cover plate 1 has a first functional layer 2, which includes a plurality of first microstructures 21. The display panel 3 includes a display body 31, and a second functional layer 4 is disposed between the display body 31 and the cover plate 1. The second functional layer 4 includes a plurality of second microstructures 41, and the radial dimension D2 of the second microstructures 41 is smaller than the radial dimension D1 of the first microstructures 21.

[0086] As mentioned above, the first functional layer 2 can play an anti-glare role, reducing the possibility of external ambient light interfering with the display effect of the display module 10 and improving the user's viewing experience.

[0087] The display body 31 can emit light to the outside. Since the second functional layer 4 is located between the cover plate 1 and the display body 31, the light emitted from the display body 31 can first pass through the second functional layer 4 and then through the first functional layer 2 before being emitted to the outside. The light can be deflected first at the second microstructure 41 and then at the first microstructure 21. Because the second functional layer 4 has multiple second microstructures 41 with small radial dimensions, it can diffuse the light. Specifically, under the action of multiple second microstructures 41, the light passing through the second functional layer 4 can be deflected in multiple directions and thus dispersed. The intensity of the dispersed light decreases, and the brightness of the light also decreases. Due to the decrease in brightness, even if different light rays mix and superimpose when passing through the first microstructure 21, no bright flashes will form. For the display screen of the display module 10, there will be no uneven brightness, thereby improving the user's viewing experience.

[0088] In related technologies, the first and second functional layers are all integrated on the cover plate. The first and second functional layers are prone to mutual influence. For example, when the second functional layer is being processed, the raw materials used in the processing can easily be sprayed or corroded onto the first functional layer, thus adversely affecting the first functional layer. At the same time, it can also easily affect the structural stability of the internal microstructure of the first and second functional layers, thereby affecting their performance. In addition, it increases the processing difficulty of the first and second functional layers, thus increasing the production difficulty of the cover plate and the display module as a whole, making it difficult to achieve mass production. Compared with related technologies, in the above embodiment, the first functional layer 2 and the second functional layer 4 are located on different carriers. That is to say, the first functional layer 2 and the second functional layer 4 are not entirely formed on the cover plate 1. This ensures that the processing of the first functional layer 2 and the processing of the second functional layer 4 do not affect each other, thereby reducing the processing difficulty of the first functional layer 2 and the second functional layer 4, ensuring the processing quality of the first functional layer 2 and the second functional layer 4 respectively, improving the stability of the structure of the first microstructure 21 and the second microstructure 41, so as to improve the effect of the first functional layer 2 and the second functional layer 4 respectively. At the same time, the above processing difficulty is low and easy to implement, which is conducive to the mass production of the display module 10.

[0089] As one specific implementation, as shown in FIG4, FIG4 is a schematic diagram of a display module 10 in another embodiment of this application. A substrate 5 is disposed on the cover plate 1 and the display panel 3, and the substrate 5 is connected to the cover plate 1 and the display panel 3 respectively. The second functional layer 4 may be disposed on the surface of the substrate 5 opposite to the cover plate 1.

[0090] The substrate 5 can be regarded as the carrier of the second functional layer 4. The material of the substrate 5 can be the same as that of the cover plate 1, or it can be different from that of the cover plate 1. In the production process of the display module 10, the cover plate 1 and the substrate 5 can be processed separately first. Then, the first functional layer 2 can be processed on the cover plate 1, and the second functional layer 4 can be processed on the substrate 5. Finally, the cover plate 1, the substrate 5 and the display panel 3 are assembled together, so that the processing of the first functional layer 2 and the processing of the second functional layer 4 will not affect each other. Compared with the above-mentioned scheme of integrating the first functional layer 2 and the second functional layer 4 on the cover plate 1, the above design is easier to process and easier to implement, which is conducive to the mass production of the display module 10.

[0091] In other embodiments, the second functional layer 4 may also be disposed on the surface of the substrate 5 facing the display panel 3.

[0092] In some embodiments, the substrate can be a glass plate. As shown in FIG5, FIG5 is a schematic diagram of a glass plate 51 disposed in a display module 10 in an embodiment of the present application. The glass plate 51 can be bonded between the cover plate 1 and the display panel 3 by an adhesive 6, which can be an OCA optical adhesive.

[0093] The second functional layer 4 can be disposed on the surface of the glass plate 51 facing the display panel 3, wherein the second microstructure 41 can protrude toward the display panel 3. Specifically, the second functional layer 4 can be formed on the surface of the glass plate 51 by a spraying process, wherein the material of the second microstructure 41 can also be glass, that is, the spraying material used in the spraying process can be a material containing silicon dioxide.

[0094] During the production of the display module 10, the cover plate 1 and the glass plate 51 can be processed from raw materials first. Then, the first functional layer 2 is processed on the cover plate 1, and the second functional layer 4 is processed on the glass plate 51. Finally, the cover plate 1, the glass plate 51 and the display panel 3 are assembled together.

[0095] The glass plate 51 provides a stable and reliable carrier for the second functional layer 4, thereby improving the stability and reliability of the second functional layer 4, which in turn improves the display effect of the display module 10 and reduces the possibility of the aforementioned flash point problem in the display module 10. At the same time, the glass plate 51 also protects the display panel 3 to ensure its normal operation. In addition, since the glass plate 51 has high strength, its installation can improve the overall strength of the display module 10, that is, improve the stability of the overall structure of the display module 10, thus helping to extend the overall service life of the display module 10.

[0096] Referring again to Figure 5, in the above embodiment, a first functional layer 2 is provided on the cover plate 1. The first functional layer 2 includes a plurality of first microstructures 21, which can protrude in a direction away from the display panel 3. Specifically, the first functional layer 2 can be formed on the surface of the cover plate 1 using a spraying process. The material of the first microstructures 21 can be the same as that of the cover plate 1; for example, the first microstructures 21 and the cover plate 1 can both be made of glass. As mentioned above, external light can be diffusely reflected on the first functional layer 2, that is, the first functional layer 2 plays an anti-glare role, thereby enabling the display module 10 to provide users with a soft display image and improve the user's viewing experience.

[0097] As shown in Figure 6, which is a schematic diagram of a glass plate 51 disposed in a display module 10 in another embodiment of this application, the second microstructure 41 on the glass plate 51 can be recessed towards the cover plate 1. That is, the second microstructure 41 can be a pit formed on the surface of the glass plate 51. Specifically, the second microstructure 41 can be formed on the surface of the glass plate 51 by an etching process, such as chemical etching or laser etching.

[0098] The recessed second microstructure 41 helps reduce the thickness of the glass plate 51. In other words, the second microstructure 41 does not require additional space in the thickness direction Z of the display module 10, thus making the display module 10 thinner and lighter overall. As mentioned above, in some embodiments, the second functional layer 4 can be formed by a spraying process. In actual production, the processing technology of the second functional layer 4 can be selected according to the usage requirements; it can be a spraying process or an etching process, thereby improving the processing flexibility of the second functional layer 4.

[0099] On the cover plate 1, the first microstructure 21 can be recessed towards the display panel 3; that is, the first microstructure 21 can be a pit formed on the surface of the cover plate 1. Specifically, the first microstructure 21 can be formed on the surface of the cover plate 1 using an etching process, such as chemical etching or laser etching.

[0100] The recessed first microstructure 21 helps to reduce the thickness of the cover plate 1, meaning that the first microstructure 21 does not need to occupy additional space in the thickness direction of the display module 10, making the display module 10 thinner and lighter overall. As mentioned above, in some embodiments, the first functional layer 2 can be formed by a spraying process. In actual production, the processing technology of the first functional layer 2 can be selected according to the actual use needs. It can be a spraying process or an etching process, thereby improving the processing flexibility of the first functional layer 2.

[0101] As shown in Figure 7, which is a schematic diagram of a glass plate 51 disposed in a display module 10 in another embodiment of this application, the second functional layer 4 can be disposed on the surface of the glass plate 51 facing the cover plate 1, wherein the second microstructure 41 can protrude in the direction close to the cover plate 1. In another embodiment, the second microstructure 41 can be recessed in the direction away from the cover plate 1, that is, the second microstructure 41 can be a pit on the glass plate 51.

[0102] In some embodiments, the substrate can be a plastic sheet. As shown in FIG8, FIG8 is a schematic diagram of a plastic sheet 52 disposed in a display module 10 in an embodiment of the present application. The plastic sheet 52 can be bonded between the cover plate 1 and the display panel 3 by an adhesive 6, which can be an OCA optical adhesive.

[0103] The plastic sheet 52 can be considered as the carrier of the second functional layer 4. The plastic sheet 52 can be a transparent plate-shaped component, and its specific material can be polyethylene terephthalate (PET), triacetate cellulose (TAC), or cyclo-olefin polymer (COP). The above materials have good light transmittance and high stability and reliability.

[0104] The second functional layer 4 can be disposed on the surface of the plastic plate 52 facing the display panel 3, wherein the second microstructure 41 can protrude toward the display panel 3. Specifically, the second functional layer 4 can be formed on the surface of the plastic plate 52 using a spraying process. Furthermore, since the plastic material has low hardness, an embossing process can also be used to form the second functional layer 4; for example, the second microstructure 41 can be pressed onto the surface of the plastic plate 52 using a roller or similar device. The embossing process is relatively simple, thereby reducing the processing difficulty of the second functional layer 4 and facilitating the mass production of the entire display module 10.

[0105] During the production of the display module 10, the cover plate 1 and the plastic plate 52 can be processed from raw materials first. Then, the first functional layer 2 is processed on the cover plate 1, and the second functional layer 4 is processed on the plastic plate 52. Finally, the cover plate 1, the plastic plate 52 and the display panel 3 are assembled together.

[0106] The plastic plate 52 has a relatively stable structure, thus providing a stable and reliable carrier for the second functional layer 4. This is beneficial for improving the stability and reliability of the second functional layer 4, thereby improving the display effect of the display module 10 and reducing the possibility of the aforementioned flash point problem. At the same time, the plastic plate 52 is lightweight, which helps to reduce the overall weight of the display module 10. Furthermore, the plastic plate 52 is easy to process and mold, reducing the production difficulty of the display module 10 and facilitating mass production. In addition, the plastic plate 52 also protects the display panel 3 to ensure its normal operation.

[0107] In other embodiments, the second functional layer 4 described above may also be disposed on the surface of the plastic plate 52 facing the cover plate 1. The second microstructure 41 may protrude towards the cover plate 1 or be recessed away from the cover plate 1.

[0108] Referring again to Figure 8, in some embodiments, the radial dimension D1 of the first microstructure 21 is 15um to 40um, for example, 15um, 18um, 20um, 22um, 24um, 26um, 30um, 32um, 34um, 36um, 38um or 40um, or other values ​​within the above range.

[0109] Haze is an important parameter of the optical transparency of transparent or translucent materials. The haze of the first functional layer 2 is 20% to 40%, for example, 20%, 22%, 24%, 26%, 28%, 30%, 32%, 34%, 36%, 38%, or 40%, or other values ​​within the above range.

[0110] By designing the radial dimension of the first microstructure 21 and the haze of the first functional layer 2 within a reasonable range, the anti-glare effect of the first functional layer 2 is improved, thereby enhancing the display effect of the display module 10 and improving the user's viewing experience.

[0111] In some embodiments, the radial dimension D2 of the second microstructure 41 is smaller than the radial dimension D1 of the first microstructure 21. The radial dimension D2 of the second microstructure 41 is 1um to 10um, for example, 1um, 2um, 3um, 4um, 5um, 6um, 7um, 8um, 9um or 10um, or other values ​​within the above range.

[0112] The haze of the second functional layer 4 is 1% to 15%, for example, 1%, 3%, 5%, 7%, 9%, 10%, 12% or 15%, or other values ​​within the above range.

[0113] By designing the radial dimension of the second microstructure 41 and the haze of the second functional layer 4 within a reasonable range, the second functional layer can effectively diffuse light, thereby improving the anti-flicker effect of the second functional layer 4 and thus improving the display effect of the display module 10, thereby enhancing the user's viewing experience.

[0114] As shown in Figure 9, which is a partial schematic diagram of the display module 10 in one embodiment of this application, the pixel unit 311 is located in the aforementioned display body 31. The radial dimension D2 of a second microstructure 41 can be smaller than the radial dimension D3 of a sub-pixel 3111. Along the thickness direction of the display module 10, the projected area of ​​a second microstructure 41 is smaller than the projected area of ​​a sub-pixel 3111. Here, the projected area of ​​the sub-pixel 3111 can be understood as the projected area of ​​the light-emitting region of the sub-pixel 3111. When the radial dimension of the second microstructure 41 is smaller than the radial dimension of the sub-pixel 3111, the light from the sub-pixel 3111 can be sufficiently diffused in the second functional layer 4, giving the second functional layer 4 an ideal anti-flicker effect.

[0115] Furthermore, the projections of multiple second microstructures 41 can fall within the projection of the same sub-pixel 3111.

[0116] For example, the projections of the second microstructures 41a, 41b, 41c, and 41d can fall within the range of a green sub-pixel 3111a. In other words, when the green sub-pixel 3111a emits light, the light rays can pass through the second microstructures 41a, 41b, 41c, and 41d, and undergo corresponding deflections. The deflected light rays can then diverge irregularly in multiple directions. In other words, each of the aforementioned second microstructures 41 disperses the relatively concentrated light rays emitted by the green sub-pixel 3111a.

[0117] The projections of the second microstructures 41e, 41f, 41g, and 41h can fall within the range of a blue sub-pixel 3111b. Similarly, when the blue sub-pixel 3111b emits light, the light rays can pass through the second microstructures 41e, 41f, 41g, and 41h, and undergo corresponding deflection. Likewise, the light rays from the blue sub-pixel 3111b will be sufficiently diverged after passing through the second microstructure 41.

[0118] The intensity of the diffused light decreases, and the brightness weakens. Even if the light from the green sub-pixel 3111a and the blue sub-pixel 3111b are deflected and mixed at the first microstructure 21, the resulting light will be relatively low in brightness and will hardly form any bright spots. Understandably, the light emitted by other sub-pixels 3111 in the display module 10 will also be diffused by the second microstructure 41 in the second functional layer 4 after passing through it, ensuring that there is almost no uneven brightness in the display screen of the display module 10, thereby improving the user's viewing experience.

[0119] As can be seen from the above, when a sub-pixel 3111 is projected onto multiple second microstructures 41, the light emitted by the sub-pixel 3111 can be deflected by the multiple second microstructures 41, allowing the light to diverge in multiple directions, that is, dispersing a concentrated beam of light into multiple beams, thereby effectively reducing the brightness of the light. This design improves the anti-flicker effect of the second functional layer 4, ensuring that the second functional layer 4 can fully diverge the light emitted by the sub-pixel 3111, thereby reducing the possibility of flickering problems in the display module 10.

[0120] The following describes a specific embodiment of a single sub-pixel 3111 and its corresponding second microstructure 41.

[0121] As shown in Figure 10, which is a schematic diagram of the projection of a sub-pixel and a second microstructure in one embodiment of this application, the solid line in the figure represents the outer contour of the projection of the light-emitting area of ​​a single sub-pixel 3111, and the dashed line represents the outer contour of the projection of the second microstructure 41 on the sub-pixel 3111. It should be noted that the projection of the second microstructure 41 can be circular; in other embodiments, the projection of the second microstructure 41 can be triangular, rectangular, or some irregular shape. The display module 10 can be applied to a 290 PPI electronic device 100. Correspondingly, the size D3 of a sub-pixel 3111 in the display module 10 can be approximately 30 μm, and the size D2 of a single second microstructure 41 can be 5 μm. Along the thickness direction of the display module 10, at least one 4x4 array of second microstructures 41 is projected into the projection of the sub-pixel 3111. That is, the light emitted by the sub-pixel 3111 can be deflected by at least 16 second microstructures 41. Each second microstructure 41 can deflect the light in a different direction. Therefore, when the light from the sub-pixel 3111 passes through the second microstructures 41, it will diverge in multiple directions, thereby reducing the brightness of the light.

[0122] Understandably, when the size of the second microstructure 41 increases, the number of second microstructures 41 corresponding to a single subpixel 3111 will increase; when the size of the second microstructure 41 decreases, the number of second microstructures 41 corresponding to a single subpixel 3111 will decrease. The specific number can be adjusted according to the actual use of the display module 10. For example, a single subpixel 3111 can correspond to 4 second microstructures 41, 9 second microstructures 41, 25 second microstructures 41, or 36 second microstructures 41. These will not be listed here.

[0123] As mentioned above, the carrier of the second functional layer can be a glass plate or a plastic plate disposed between the cover plate and the display panel. In the embodiments of this application, the polarizer of the display module can also be used as the carrier of the second functional layer. The structure of the polarizer with the second functional layer will be further described below with reference to the accompanying drawings.

[0124] As shown in Figure 11, which is an exploded view of the display module 10 in another embodiment of this application, the display panel 3 includes a polarizer 32 and a display body 31. The polarizer 32 is located on the side of the display body 31 near the cover plate 1 and is connected to the cover plate 1 and the display body 31 respectively. Specifically, the cover plate 1 can be connected to the polarizer 32 and the display body 31 by OCA optical adhesive (not shown in the figure). The second functional layer 4 can be disposed on the surface of the polarizer 32 facing the cover plate 1, wherein the second microstructure 41 can protrude in the direction close to the cover plate 1.

[0125] As shown in Figure 12, which is an exploded view of the display module 10 in another embodiment of this application, the second functional layer 4 can also be disposed on the surface of the polarizer 32 away from the cover plate 1, wherein the second microstructure 41 can protrude in the direction away from the cover plate 1.

[0126] In the above embodiments, the second microstructure 41 can also be a pit.

[0127] Before assembling the polarizer 32 with the display body 31, a second functional layer 4 can be formed on the surface of the polarizer 32 by spraying, etching or embossing. After the polarizer 32 and the display body 31 are assembled into the display panel 3, they are then assembled with the cover plate 1 to form the display module 10.

[0128] In related technologies, the first functional layer 2 and the second functional layer 4 are all integrated on the polarizer 32. This makes it easy for the first functional layer 2 and the second functional layer 4 to interfere with each other, similar to the case where the first functional layer 2 and the second functional layer 4 are all integrated on the cover plate 1, and will not be repeated here. In the above embodiment, the carrier of the first functional layer 2 is the cover plate 1, and the carrier of the second functional layer 4 is the polarizer 32 in the display panel 3. That is to say, the first functional layer 2 and the second functional layer 4 are respectively set on different carriers, so that the processing of the first functional layer 2 and the processing of the second functional layer 4 will not interfere with each other, reducing the processing difficulty of the first functional layer 2 and the second functional layer 4, and facilitating the mass production of the display module 10.

[0129] In one specific implementation, the second functional layer can be disposed on the protective layer of the polarizer. As shown in Figure 13, which is a schematic diagram of the polarizer 32 in one embodiment of this application, the polarizer 32 may include a polarizing layer 321 and a first protective layer 322 connected to the polarizing layer 321. The first protective layer 322 may be located on the side of the polarizer 32 closer to the cover plate 1 (as shown in Figure 11). The polarizing layer 321 may be a specially treated polyvinyl alcohol (PVA) layer, which mainly functions to polarize light. That is, the polarizing layer 321 can utilize the polarization characteristics of light to control the light emitted from the display body, thereby realizing the normal display function of the display module 10. The first protective layer 322 may be a TAC layer or a PET layer, which provides support and protection for the polarizer 32, thereby helping to extend the service life of the entire polarizer 32.

[0130] The second functional layer 4 can be disposed on the first protective layer 322. Specifically, along the thickness direction Z of the polarizer 32, the second functional layer 4 can be disposed on either the upper or lower surface of the first protective layer 322. The second microstructure 41 can be a protrusion or a pit on the surface of the first protective layer 322. Disposing of the second functional layer 4 on the first protective layer 322 reduces the possibility of the second functional layer 4 affecting the polarizer 321. This eliminates the need for spraying, etching, or imprinting on the polarizer 321, thus preserving its polarization effect and improving the reliability of the polarizer 32.

[0131] As shown in Figure 14, which is a schematic diagram of a polarizer 32 in another embodiment of this application, the polarizer 32 may include a polarizing layer 321 and a second protective layer 323 connected to the polarizing layer 321. The second protective layer 323 may be located on the side of the polarizer 32 closer to the display body 31 (as shown in Figure 11). The second protective layer 323 may be a TAC layer or a PET layer. The second protective layer 323 plays a supporting and protective role in the polarizer 32, thereby helping to extend the service life of the entire polarizer 32.

[0132] The second functional layer 4 can be disposed on the second protective layer 323. Specifically, along the thickness direction Z of the polarizer 32, the second functional layer 4 can be disposed on either the upper or lower surface of the second protective layer 323. The second microstructure 41 can be a protrusion or a pit on the surface of the second protective layer 323. The principle of disposing the second functional layer 4 on the second protective layer 323 is the same as that of disposing the second functional layer on the first protective layer described above, and will not be repeated here.

[0133] The second microstructure mentioned above can be a protrusion or a pit, which can be formed on a corresponding carrier through processes such as spraying, etching, or imprinting. In the embodiments of this application, the second microstructure can also be a transparent particle that can deflect light; its material can be plastic or other transparent materials. The second functional layer with transparent particles will be further described below with reference to the accompanying drawings.

[0134] As mentioned above, the polarizer has a protective layer, which can be a TAC or PET plastic film layer. The second functional layer can be located inside the protective layer, that is, the aforementioned transparent particles (i.e., the second microstructure) can fill the interior of the protective layer.

[0135] As a specific embodiment, as shown in Figure 15, which is a schematic diagram of the polarizer 32 in another embodiment of this application, the second functional layer 4 can be formed inside the first protective layer 322 on one side of the polarizer 321. The second microstructure 41 can be a transparent particle, which can be added to the first protective layer 322 during its manufacturing process; that is, the transparent particle and the first protective layer 322 are integral. This design eliminates the need for etching, spraying, or other processes on the first protective layer 322, simplifying the manufacturing process of the polarizer 32 and the entire display module 10, and facilitating mass production of the display module 10.

[0136] In another embodiment, the aforementioned transparent particles can be disposed within the second protective layer, that is, the second functional layer can also be formed inside the second protective layer.

[0137] As shown in Figure 16, which is a schematic diagram of the polarizer 32 in another embodiment of this application, the polarizing layer 321 can be bonded to the first protective layer 322 via the colloid 6, which can be OCA optical adhesive. The second microstructure 41 can be a transparent particle, which can be disposed in the colloid 6 between the polarizing layer 321 and the first protective layer 322. That is, the second functional layer 4 can be formed in the colloid 6. Specifically, before using the colloid 6, the aforementioned transparent particles (i.e., the second microstructure 41) can be mixed into the colloid 6, making the colloid 6 and the second functional layer 4 a whole. The above design eliminates the need for etching, spraying, and other processes on the first protective layer 322, simplifying the production process of the polarizer 32 and the entire display module 10, and facilitating the mass production of the display module 10.

[0138] In other embodiments, the polarizing layer can also be bonded to the second protective layer via an colloid, and transparent particles can be added to the colloid between the polarizing layer and the second protective layer, thereby making the colloid and the second functional layer a whole.

[0139] As shown in Figure 17, which is a schematic diagram of the polarizer 32 and the protective film 33 in one embodiment of this application, a protective film 33 may be provided on the surface of the polarizer 32. Specifically, the protective film 33 may be adhered to the surface of the polarizer 32. The protective film 33 can protect the polarizer 32, reduce the possibility of scratches or damage to the surface of the polarizer 32, and extend the overall service life of the polarizer 32.

[0140] The protective film 33 is provided with a second functional layer 4, meaning that the protective film 33 can serve as a carrier for the second functional layer 4. Specifically, the protective film 33 can be a PET film or a TAC film. The second microstructure 41 can be transparent particles (the second microstructure shown in Figure 17 is a transparent particle) or protrusions or pits formed on the surface of the protective film 33. This design eliminates the need for spraying, etching, or imprinting on the internal structure of the polarizer 32. In other words, the second functional layer 4 does not affect the internal structure of the polarizer 32, improving the stability and reliability of the polarizer 32 and extending its service life.

[0141] As shown in Figure 18, which is a schematic diagram of the display module 10 in another embodiment of this application, the cover plate 1 can be connected to the display panel 3 via the colloid 6. The second microstructure 41 can be the aforementioned transparent particles, which can be disposed in the colloid 6 between the cover plate 1 and the display panel 3, that is, the colloid 6 and the second functional layer 4 form a whole. The above design eliminates the need for etching, spraying, or other processing on the substrate 5 or the polarizer 32, simplifying the entire production process of the display module 10 and facilitating the mass production of the display module 10.

[0142] This application provides an electronic device. As shown in FIG19, FIG19 is a schematic diagram of an electronic device 100 in one embodiment of this application. The electronic device 100 includes a housing 20 and a display module 10. The display module 10 is installed inside the housing 20. The display module 10 can be the display module 10 described in the above embodiments, so that the electronic device 100 can provide users with a clear and comfortable display screen, thereby improving the user experience of the electronic device 100.

[0143] Referring again to Figure 19, in some embodiments, the electronic device 100 can be a curved screen mobile phone, that is, the display module 10 can be a curved display module 10, that is, the display module 10 can have a certain curvature.

[0144] As shown in Figure 20, which is an exploded view of a curved display module 10 according to an embodiment of this application, the edges of the cover plate 1 and the display panel 3 in the curved display module 10 may have a certain curvature. Specifically, the edge of the cover plate 1 may have a first arc-shaped area 11, on which a first functional layer 2 is disposed. The edge of the display body 31 may have a second arc-shaped area 312, and a portion of the second functional layer 4 is located between the first arc-shaped area 11 and the second arc-shaped area 312. That is, a second functional layer 4 is located between the first arc-shaped area 11 and the second arc-shaped area 312. Specifically, the edge of the glass plate or plastic plate that serves as the carrier of the second functional layer 4 may also have a certain curvature, and its shape may correspond to the first arc-shaped area 11 and the second arc-shaped area 312.

[0145] As mentioned above, the first functional layer 2 serves to prevent glare, but it can cause flickering issues. For curved-screen phones, the pixel units within the second arc-shaped area 312 of the display body 31 deform as the area bends, resulting in a larger area of ​​flickering caused by light refraction through the second arc-shaped area 312. In other words, the flickering problem is more pronounced on curved-screen phones. By setting a second functional layer 4 between the first arc-shaped area 11 and the second arc-shaped area 312, the flickering problem on curved-screen phones can be solved, thereby improving the user experience. The principle behind this has been explained above and will not be repeated here.

[0146] Meanwhile, curved screen phones also suffer from a "green edge" problem, where users can see a green light emanating from the edges of the curved screen (i.e., the curved area of ​​the screen) from a certain angle. This is caused by optical color difference in the light emitted from the second curved area 312 of the display body 31 on the first curved area 11 of the cover plate 1. By setting a second functional layer 4 between the first curved area 11 and the second curved area 312, the light emitted from the edge of the display body 31 is diffused before passing through the cover plate 1, reducing the intensity of the light. After the light undergoes the aforementioned deviation on the cover plate, users will hardly see any obvious green light at the edge of the phone, thus improving the "green edge" problem and enhancing the user experience.

[0147] As shown in Figure 21, which is a schematic diagram of an electronic device 100 in another embodiment of this application, the dashed lines represent creases on the display module 10. The electronic device 100 can be a foldable mobile phone, that is, the display module 10 can be a flexible display module 10.

[0148] As shown in Figure 22, which is an exploded view of a flexible display module 10 in one embodiment of this application, the flexible display module 10 is in a folded state. In the flexible display module 10, both the cover plate 1 and the display panel 3 have a certain degree of flexibility, allowing the flexible display module 10 to be unfolded and folded as a whole. The cover plate 1 includes a first folding area 12, and the display body includes a second folding area 313. When the flexible display module 10 is in a folded state, both the first folding area 12 and the second folding area 313 are in an approximately "U"-shaped folded state.

[0149] A first functional layer 2 is provided on the first folding area 12. A portion of the second functional layer 4 is located between the first folding area 12 and the second folding area 313, that is, there is a second functional layer 4 between the first folding area 12 and the second folding area 313. Specifically, the glass plate or plastic plate that serves as the carrier of the second functional layer 4 also has a certain degree of flexibility, and it can be unfolded and folded together with the cover plate 1 and the display panel 3.

[0150] Referring to Figures 21 and 22, the electronic device 100 undergoes repeated unfolding and folding during use, which can easily cause creases to appear on the first folding area 12 of the cover plate 1. These creases can affect the display effect of the flexible display module 10. As mentioned above, a first functional layer 2 with anti-glare effect is provided on the first folding area 12. Therefore, external light will diffusely reflect at the crease of the first folding area 12 instead of specularly reflecting, thus visually weakening the crease. In other words, users will not see obvious creases on the display module 10 during use. At the same time, a second functional layer 4 is provided between the first folding area 12 and the second folding area 313.
