[0012] The second protective layer is disposed on the side of the functional layer away from the first protective layer, and the strength of the second protective layer is greater than that of the first protective layer.

[0016] In some embodiments, the display module has a bending area; the bending shape of the area corresponding to the bending area on the protective layer matches the bending shape of the bending area, and the bending shape of the area corresponding to the bending area on the base layer matches the bending shape of the bending area.

[0017] In some embodiments, the display module is a flexible liquid crystal display screen; along the light emission direction of the display module, the display module includes a lower polarizer, an array substrate, a liquid crystal layer, a counter substrate, and an upper polarizer stacked sequentially.

[0018] The display panel also includes a touch layer, which is positioned between the display module and the protective layer.

[0019] In some embodiments, along the light emission direction of the display module, the functional layer includes a polarizing layer, a brightness enhancement layer, a diffusion layer, a buffer layer, and an antistatic layer stacked sequentially.

[0020] In some embodiments, the polarization direction of the polarizing layer is the same as the polarization direction of the upper polarizer of the display module;

[0021] The polarizing layer includes a polarizing layer and a protective layer.

[0030] The beneficial effects of this application: Unlike the prior art, this application provides a display panel and a display device. The display panel includes a display module and a protective layer. The protective layer is disposed on the light-emitting side of the display module and includes a first protective layer, a functional layer, and a second protective layer. This application improves the protection of the display module by making the inner first protective layer include a layered protective base and an adhesive layer, allowing the adhesive layer to hold together fragments and prevent them from flying when the protective base breaks. Simultaneously, by making the strength of the outer second protective layer greater than that of the first protective layer, the impact resistance of the second protective layer is improved, and when combined with the first protective layer, the protection capability for the display module is effectively enhanced. Furthermore, by providing a functional layer between the first and second protective layers, and ensuring that the function includes at least a buffer layer, the external force transmitted to the second protective layer can be buffered, reducing the risk of the first protective layer breaking and the display module being damaged. Thus, through the above three-layer protective layer structure, the shatterproof capability of the display panel can be effectively improved. Attached Figure Description

[0051] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0052] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a display panel provided in one embodiment of this application.

[0053] In this embodiment, a display panel 10 is provided, the display panel 10 including:

[0054] Display module 13;

[0055] A protective layer 12 is disposed on the light-emitting side of the display module 13 to protect the display module 13;

[0056] The protective layer 12 includes:

[0057] The first protective layer 121 is disposed on the light-emitting side of the display module 13, and includes a protective base layer 1211 and an adhesive layer 1212 stacked together. The adhesive layer 1212 is used to bond the fragments of the protective base layer 1211 after it is broken.

[0058] The functional layer 123 is disposed on the side of the first protective layer 121 away from the display module 13, and includes at least a buffer layer 1234;

[0059] The second protective layer 122 is disposed on the side of the functional layer 123 away from the first protective layer 121, and the strength of the second protective layer 122 is greater than the strength of the first protective layer 121.

[0060] The first protective layer 121 is disposed on the light-emitting side of the display module 13, providing basic protection for the entire display panel 10. The first protective layer 121 includes a protective base layer 1211 and an adhesive layer 1212 stacked together. The adhesive layer 1212 can bond fragments when the protective base layer 1211 is broken, thereby preventing fragments from flying and causing danger, and providing protection for the display module 13.

[0061] The second protective layer 122 is disposed on the side of the functional layer 123 away from the first protective layer 121. Compared with the first protective layer 121, its strength is greater than that of the first protective layer 121, thereby resisting external impact and further protecting the display module 13 and improving the impact resistance of the display panel 10.

[0062] The functional layer 123 is disposed on the side of the first protective layer 121 away from the display module 13, and includes at least a buffer layer 1234. Specifically, the buffer layer 1234 can be a polyurethane layer, so that the buffer layer 1234 can effectively relieve the impact force from the outside, thereby protecting the structure of the display module 13 and keeping it stable.

[0063] Specifically, in this embodiment, by setting the protective layer 12 on the light-emitting side of the display module 13, and making the protective layer 12 include the first protective layer 121, the functional layer 123 and the second protective layer 122 in sequence, the multi-layer protective layer 12 has a significant improvement in functional integration and protection capability compared with the traditional single structure or simple stacked protective layer 12.

[0064] In a specific embodiment, the protective base layer 1211 is a glass layer, the adhesive layer 1212 is a polyvinyl butyral layer, and the second protective layer 122 is a chemically strengthened glass layer.

[0065] The glass layer can be made of one or more of polyimide (PI) or acrylic (PMMA) glass, and the adhesive layer 1212 can be made of polyvinyl butyral (PVB). In a specific manufacturing process, polyvinyl butyral can be coated on the side of the protective base layer 1211 away from the display module 13 to form the adhesive layer 1212 on the protective base layer 1211. This allows the adhesive layer 1212 to bond the fragments together when the glass layer breaks, preventing the fragments from flying and causing danger.

[0066] The second protective layer 122 is a chemically strengthened glass layer. Specifically, the chemically strengthened glass can enhance its strength and impact resistance through an ion exchange process, thereby improving the strength and impact resistance of the second protective layer 122.

[0067] In this embodiment, the double-layer protective structure formed by the combination of the first protective layer 121 and the second protective layer 122 can not only prevent the protective layer 12 from breaking and causing danger by flying fragments, but also effectively resist external impact forces, effectively protect the structure of the display module 13 from external damage, greatly improve the shatterproof capability of the display panel 10, and thus protect the precision display structure inside the display panel 10 in all aspects.

[0068] Please see Figure 2 , Figure 2 This is a schematic diagram of the structure of a functional layer provided in an embodiment of this application. In this embodiment, along the light emission direction of the display module 13, the functional layer 123 includes a brightness enhancement layer 1232, a diffusion layer 1233, a buffer layer 1234, and an antistatic layer 1235 stacked sequentially.

[0069] Among them, the brightening layer 1232, the diffusion layer 1233, the buffer layer 1234 and the antistatic layer 1235 are stacked sequentially on the light-emitting side of the display module 13.

[0070] Among them, the brightening layer 1232 can be a polyethylene terephthalate film layer, which has high transparency and good optical properties, and can effectively improve the utilization rate of light and increase the screen brightness.

[0071] The diffusion layer 1233 can be a polystyrene film layer, which can evenly disperse the concentrated light, making the screen display more uniform, and can eliminate bright spots and dark areas, thus improving the overall visual effect.

[0072] Among them, the buffer layer 1234 can be a polyurethane layer, which has good elasticity and shock absorption properties, and can effectively buffer external impact forces and protect the internal display structure.

[0073] Among them, the antistatic layer 1235 can be a thin film layer that adsorbs quaternary ammonium salt surfactant molecules. This film layer can conduct away static electricity in time, avoid the interference of static electricity on the display effect, and at the same time prevent static electricity from attracting dust and keeping the screen clean.

[0074] Specifically, by placing the antistatic layer 1235 at the outermost layer position, static electricity can be promptly dissipated, and dust can be effectively prevented from being attracted by static electricity, thus keeping the screen clean. By placing the buffer layer 1234 below the antistatic layer 1235, the distance between the buffer layer 1234 and the second protective layer 122 is closer, thereby ensuring the buffer layer 1234's buffering effect against external impacts and protecting the underlying optical film layers. By placing the brightness enhancement layer 1232 closer to the display module 13, the emitted light from the display module 13 can reach the brightness enhancement layer 1232 first, thereby improving the brightness enhancement effect of the brightness enhancement layer 1232. By placing the diffusion layer 1233 above the brightness enhancement layer, the emitted light is brightened before diffusion, which not only makes the emitted light more uniform but also ensures the brightness enhancement effect of the emitted light.

[0075] In this embodiment, the brightness enhancement layer 1232, diffusion layer 1233, buffer layer 1234 and antistatic layer 1235 of the above-mentioned functional layer 123 are sequentially stacked on the light-emitting side of the display module 13. The layers work together to optimize the display effect and comprehensively improve the visual experience and screen stability. Compared with the design of the functional layer 123 being randomly arranged or lacking some functional film layers, the functional layer 123 provided in this embodiment greatly improves the overall performance of the display panel 10.

[0076] Please see Figure 3 , Figure 3 This is a schematic diagram of the structure of the display panel provided in the second embodiment of this application. In this embodiment, the display module 13 is a flexible display screen; the display panel 10 also includes a base layer 11, which is disposed on the backlight side of the display module 13 and is used to support and protect the display module 13; the base layer 11 is made of aluminum plate, aluminum alloy plate or titanium alloy plate.

[0077] The display module 13 is a flexible display screen, which can be a liquid crystal display (LCD), an organic light-emitting diode (OLED) display screen, a light-emitting diode (LED) display screen, a micro-LED display screen, an e-ink screen, or other flexible display screens capable of display functions. Because the display module 13 is a flexible display screen, its structure is unstable and it is prone to deformation during display operations, leading to image distortion.

[0078] To address the aforementioned technical issues, in this embodiment, the display panel 10 is further provided with a base layer 11. The base layer 11 is disposed on the backlight side of the display module 13. Specifically, the base layer 11 can be a lightweight metal plate with a certain strength, such as an aluminum plate, an aluminum alloy plate, or a titanium alloy plate. This gives the base layer 11 high strength and lightweight characteristics, which not only provides stable support for the display module 13 and ensures the stability of the overall structure of the display module 13, but also further protects the flexible display body and effectively ensures that the display is not affected by deformation. Moreover, it does not add too much weight, which is beneficial to the lightweight design of electronic devices.

[0079] Please see Figure 4 , Figure 4 This is a schematic diagram of the structure of the display panel provided in the third embodiment of this application. In this embodiment, the display module 13 has a bending area 136; the bending shape of the area on the protective layer 12 corresponding to the bending area 136 matches the bending shape of the bending area 136, and the bending shape of the area on the base layer 11 corresponding to the bending area 136 matches the bending shape of the bending area 136.

[0080] Specifically, the display module 13 is a flexible display screen body. The display module 13 bends outward at the edge of the screen body to form a specific bending area 136, thereby making the display module 13 a curved screen body. The bending area 136 is the key part to realize the flexible bending function of the display module 13.

[0081] Furthermore, corresponding to the aforementioned bending area 136 of the display module 13, the protective layer 12 also has a corresponding bending area at its edge, and this bending area matches the bending shape of the bending area 136 of the display module 13, thereby enabling the protective layer 12 to completely adhere to the display module 13, ensuring both the protective effect and the display effect of the display module 13. That is, the protective layer 12 is disposed on the light-emitting side of the display module 13, and the portion of it corresponding to the bending area 136 of the display module 13 has a shape consistent with the bending shape of the bending area 136 of the display module 13, thereby enabling the protective layer 12 and the display module 13 to adhere to each other. In some specific embodiments, when the bending shape of the bending area 136 of the display module 13 is a specific arc, the bending area 136 of the protective layer 12 will also bend with the same arc to tightly adhere to the bending area 136 of the display module 13.

[0082] Similarly, in this embodiment, the bending area of ​​the base layer 11 matches the bending shape of the bending area 136 of the display module 13. That is, the base layer 11 is disposed on the backlight side of the display module 13, and the portion of it corresponding to the bending area 136 of the display module 13 has the same bending shape as the bending area 136 of the display module 13, thereby making the base layer 11 and the display module 13 fit together. In some specific embodiments, when the bending shape of the bending area 136 of the display module 13 is a specific arc, the bending area 136 of the base layer 11 will also bend with the same arc to tightly fit the bending area 136 of the display module 13.

[0083] Please see Figure 5 , Figure 5 This is a schematic diagram of the structure of the display panel provided in the fourth embodiment of this application. In this embodiment, the display module 13 is a flexible liquid crystal display screen; along the light emission direction of the display module 13, the display module 13 includes a lower polarizer 131, an array substrate 132, a liquid crystal layer 133, a counter substrate 134, and an upper polarizer 135 stacked in sequence.

[0084] The lower polarizer 131 is used to filter the light provided by the backlight assembly, filtering the unpolarized light from the backlight source into linearly polarized light.

[0085] An array substrate 132 and a counter substrate 134 are disposed opposite to each other, and a liquid crystal layer 133 is disposed between the array substrate 132 and the counter substrate 134. An electric field at the pixel level is formed between the array substrate 132 and the counter substrate 134 to control the deflection angle of the liquid crystal located in the electric field, so that the linearly polarized light passing through the lower polarizer 131 is partially emitted after being deflected by the liquid crystal to display the corresponding grayscale.

[0086] An upper polarizer is disposed on the side of the substrate 134 away from the liquid crystal layer 133 to control the emission of light passing through the liquid crystal layer 133, thereby displaying the corresponding grayscale or black. The polarization direction of the upper polarizer 135 matches the polarization direction of the lower polarizer 131, and can be specifically set according to the type of liquid crystal display. For example, if the liquid crystal display is a vertical alignment (VA) type, then the polarization direction of the upper polarizer 135 is perpendicular to the polarization direction of the lower polarizer 131.

[0087] Please see Figure 6 , Figure 6 This is a schematic diagram of the structure of a functional layer provided in another embodiment of this application. In this embodiment, along the light emission direction of the display module 13, the functional layer 123 includes a polarizing layer 1231, a brightness enhancement layer 1232, a diffusion layer 1233, a buffer layer 1234, and an antistatic layer 1235 stacked sequentially.

[0088] The polarizing layer 1231 can be used to further filter the emitted light from the display module 13. The polarization direction of the polarizing layer 1231 is the same as that of the upper polarizer 135. By controlling the polarization direction of the emitted light from the display module 13, it is ensured that the light can correctly present the image and reduce the reflection of ambient light, thereby reducing screen glare and improving visibility under strong light.

[0089] The materials, structures, and functions of the brightening layer 1232, the diffusion layer 1233, the buffer layer 1234, and the antistatic layer 1235 are the same as or similar to those of the brightening layer 1232, the diffusion layer 1233, the buffer layer 1234, and the antistatic layer 1235 involved in the above embodiments, and can achieve the same technical effects. For details, please refer to the relevant introduction above.

[0090] Please see Figure 7 , Figure 7 This is a schematic diagram of the structure of a polarizing layer provided in an embodiment of this application. In this embodiment, the polarization direction of the polarizing layer 1231 is the same as the polarization direction of the upper polarizer 135 of the display module 13; the polarizing layer 1231 includes a polarizing layer 12311 and a protective layer 12312. The polarizing layer 12311 is disposed on the side of the first protective layer 121 away from the display module 13, and the protective layer 12312 is disposed on the side of the polarizing layer 12311 away from the first protective layer 121, for protecting the polarizing layer 12311.

[0091] The polarization direction of the polarization layer 1231 is the same as that of the upper polarizer 135 of the display module 13, thereby further filtering the emitted light of the display module 13 to enhance the control of the polarization direction of the light, thereby improving the contrast and color reproduction of the display module 13 and improving the clarity and fidelity of the displayed image.

[0092] The polarizing layer 1231 includes a polarizing layer 12311 and a protective layer 12312. The polarizing layer 12311 is disposed on the side of the first protective layer 121 away from the display module 13, and its material can be polyvinyl alcohol (PVA), enabling the polarizing layer 12311 to selectively absorb light and achieve the polarization function. The protective layer 12312 is disposed on the side of the polarizing layer 12311 away from the first protective layer 121, and its material can be cellulose triacetate (TAC), effectively protecting the polarizing layer 12311 while optimizing optical performance.

[0093] In this embodiment, the polarizing layer 1231 includes a polarizing layer 12311 and a protective layer 12312. The polarizing layer 12311, as the core layer of the polarizing layer 1231, requires its molecular orientation to be consistent with the upper polarizer 135 of the display module 13 to achieve effective filtering and polarization control of the incident light. The protective layer 12312, while providing effective protection and support, adopts a single-layer triacetate cellulose (TAC) structure design, reducing the overall film thickness and aligning with the trend towards thinner and lighter electronic devices. Furthermore, by adjusting the thickness and optical parameters of the protective layer 12312, the first protective layer 121, the buffer layer 1234, and the protective layer 12312 can jointly provide physical protection for the polarizing layer 12311, thereby reducing damage to the polarizing layer 12311 caused by environmental factors (such as moisture and ultraviolet radiation). Further, the single-layer protective layer 12312 design of the polarizing layer 1231 can also avoid light scattering or phase delay problems that may be introduced by multi-layer structures, thereby reducing the impact on polarization efficiency.

[0094] Please see Figure 8 , Figure 8 This is a schematic diagram of the structure of the display panel provided in the fifth embodiment of this application. In this embodiment, the display panel 10 further includes a touch layer 14, which is disposed between the display module 13 and the protective layer 12.

[0095] Specifically, the touch layer 14 is disposed between the display module 13 and the protective layer 12 to realize the touch function of the display panel 10. The touch layer 14 is a key component for realizing "human-computer interaction" in the display panel 10. With the development of flexible technology and foldable devices, the touch layer 14 can also take into account flexibility and thinness to meet the needs of more scenarios.

[0096] Please see Figure 9 , Figure 9 This is a schematic diagram of the structure of the display device provided in the first embodiment of this application. In this embodiment, a display device is provided, including:

[0097] Display panel 10;

[0098] The driver circuit board 20 is electrically connected to the display module 13 of the display panel 10 and is used to drive the display module 13 to display the corresponding image.

[0099] The display panel 10 includes a base layer 11, a display module 13, and a protective layer 12 stacked sequentially. The base layer 11 is disposed on the backlight side of the display module 13, the protective layer 12 is disposed on the light-emitting side of the display module 13, and the display module 13 is disposed between the base layer 11 and the protective layer 12. The specific structure and function of the base layer 11, the display module 13, and the protective layer 12 are the same as or similar to those of the base layer 11, the display module 13, and the protective layer 12 involved in the above embodiments, and can achieve the same technical effects. For details, please refer to the relevant description above.

[0100] The driving circuit board 20 can be electrically connected to the display panel 10 via a flexible printed circuit board (FPC) or a chip-on-film (COF) film. The driving circuit board 20 can be disposed on the backlight side of the display panel 10. The flexible connecting portion of the FPC or COF is bent along the side wall of the display panel 10 toward the display module 13 to achieve electrical connection with the display module 13, thereby driving the display module 13 to display the corresponding image, while avoiding occupying display area space.

[0101] Please see Figure 10 , Figure 10 This is a schematic diagram of the structure of the display device provided in the second embodiment of this application. In this embodiment, the display module 13 is a flexible liquid crystal display screen; the display panel 10 also includes a base layer 11, which is disposed on the backlight side of the display module 13 and is used to support and protect the display module 13;

[0102] The display device also includes a backlight assembly 30, which includes a light strip 31 and a light guide plate 32. The light guide plate 32 is disposed between the base layer 11 and the display module 13, and the light guide plate 32 and the display module 13 have the same shape. The light strip 31 is disposed on one side of the side wall of the light guide plate 32.

[0103] The base layer 11 is used to support and protect the flexible liquid crystal display screen. It has the characteristics of high strength and light weight, which not only provides a stable support for the display module 13 and ensures the stability of the overall structure of the display module 13, but also further protects the flexible display screen and effectively ensures that the display is not affected by deformation. Moreover, it does not add too much weight, which is conducive to the thin and light design of electronic devices.

[0104] The driving circuit board 20 can be disposed on the side of the base layer 11 away from the display panel 10. The driving circuit board 20 can be electrically connected to the display panel 10 via a flexible printed circuit board (FPC) or a chip-on-film (COF) film. Specifically, the flexible connection portion of the FPC or COF bends along the sidewall of the base layer toward the display module 13 of the display panel 10 to achieve electrical connection with the display module 13, thereby driving the display module 13 to display the corresponding image. At the same time, it can avoid occupying display area space, and the rigid support of the base layer 11 protects the circuit at the bend and reduces stress damage.

[0105] Specifically, the backlight assembly 30 includes a light strip 31 and a light guide plate 32. The light guide plate 32 is disposed between the base layer 11 and the display module 13. The material of the light guide plate 32 can be polymethyl methacrylate (PMMA, acrylic), polycarbonate (PC), or polystyrene (PS). The shape and size of the light guide plate 32 are the same as those of the display module 13 to improve the backlight zoning accuracy and brightness uniformity.

[0106] Furthermore, in this embodiment, the backlight assembly 30 has a side-lit structure, with the light strip 31 disposed on one side of the sidewall of the light guide plate 32. The light strip 31 can be a micro light-emitting diode (Micro LED) or a regular light-emitting diode (LED) as a point light source. Its light is guided to the light guide plate 32, thereby converting it into a surface light source to provide light to the display panel 10. In this embodiment, by placing the backlight assembly 30 between the base layer 11 and the display module 13, the light source of the backlight assembly 30 can be directly provided to the display module 13 without being obstructed by the base layer 11.

[0107] Please see Figure 11 , Figure 11 This is a schematic diagram of the display device provided in the third embodiment of this application. In this embodiment, there are multiple light strips 31, which are disposed between the light guide plate 32 and the base layer 11.

[0108] In this embodiment, the backlight assembly 30 has a direct-lit structure, with multiple LED strips 31 disposed between the light guide plate 32 and the base layer 11. This allows the light from the LED strips 31 to be guided to the light guide plate 32 and converted into a surface light source to provide light to the display module 13. The material and structure of the light guide plate 32 are the same as or similar to those of the light guide plate 32 described in the previous embodiment, and can achieve the same technical effect. For details, please refer to the relevant description above. In this embodiment, by disposing the backlight assembly 30 between the base layer 11 and the display module 13, the light source of the backlight assembly 30 can be directly provided to the display module 13 without being obstructed by the base layer 11.

[0109] Please see Figure 12 , Figure 12 This is a schematic diagram of the structure of the display device provided in the fourth embodiment of this application. In this embodiment, there are multiple light strips 31, which are disposed on the side of the base layer 11 away from the display module 13; the base layer 11 is provided with multiple hollow portions 111 so that the light from the light strips 31 can pass through the base layer 11.

[0110] In this embodiment, the backlight assembly 30 still has a direct-lit structure. The difference is that, in this embodiment, the light strip 31 is disposed on the side of the base layer 11 away from the display module 13. The base layer 11 has multiple cutouts 111, allowing the light from the light strip 31 to pass directly through the base layer 11 and reach the light guide plate 32. The material and structure of the light guide plate 32 are the same as or similar to those of the light guide plate 32 described in the previous embodiment, and achieve the same technical effects; please refer to the relevant description above for details.

[0111] In this embodiment, by providing multiple perforations 111 on the base layer 11, the light from the lamp strip 31 can directly pass through the base layer 11 and reach the light guide plate 32. This allows the base layer 11 to both transmit light and act as a reflective layer, reducing light loss. Specifically, the light-emitting elements on the lamp strip 31 can be correspondingly arranged with the perforations 111, meaning the orthogonal projection of the light-emitting element onto the base layer 11 is located at the perforation 111. This allows more light from the light-emitting element to pass through the base layer 11, improving light utilization.

[0112] In some specific embodiments, the display device can be any product or component with display functionality, such as a mobile phone, tablet computer, television, monitor, laptop computer, digital photo frame, or navigator. The display device can be used to display images. This disclosure does not limit the type of display device.

[0113] The above are merely embodiments of this application and do not limit the scope of patent protection of this application. Any equivalent structural or procedural changes made using the content of this application’s specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection of this application.
