Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0025] With the popularization of electronic devices, as a core component of human-computer interaction, display screens are widely used in consumer electronic products such as smartphones, tablets, laptops, and smartwatches. A display screen generally includes a display panel and a protective glass, and the protective glass covers the surface of the display panel to provide protection for the display panel. In the related art, the impact resistance and drop resistance of the protective glass are poor, and it is easy to crack or break when subjected to external impact or drop.

[0026] To solve the above problems, referring to Figure 1 and Figure 2 , an embodiment of the present application provides a display screen 2, which includes a display panel 21, a protective glass 22, and an energy-absorbing colloid layer 23. The protective glass 22 covers the surface where the display output area of the display panel 21 is located; the energy-absorbing colloid layer 23 covers the protective glass 22 and is used to absorb the energy of external impact to protect the protective glass 22.

[0027] In the embodiment of the present application, the display panel 21 is the core component of the display screen 2 and is responsible for displaying images and content. The display output area of the display panel 21 refers to the effective area on the display panel 21 that is actually used to display images, videos, or texts. That is, the area on the display panel 21 composed of a pixel array, and these pixels can be driven to emit light (or modulate light) to form visible images or content.

[0028] In the embodiment of the present application, the protective glass 22 covers the surface where the display output area of the display panel 21 is located to protect the display panel 21 and provide additional functional support. The structural form of the protective glass 22 has various possibilities. If it is applied to a mobile phone, a tablet computer, a laptop computer, etc., where the display screen must be fixed to the electronic device and cannot be deformed anymore, the protective glass 22 can be aluminosilicate glass. If it is applied to a folding mobile phone, a folding laptop, etc., where the display screen must be fixed to the electronic device and can still be deformed based on the deformation of the electronic device, the protective glass can be ultra-thin glass (UTG), or flexible glass. The embodiment of the present application does not limit this.

[0029] In the embodiment of the present application, the energy-absorbing colloid layer 23 covers the protective glass 22 to absorb the impact energy when the protective glass 22 is subjected to external impact. Here, the structural form of the energy-absorbing colloid layer 23 has various possibilities. For example, the energy-absorbing colloid layer 23 can be a single-layer structure formed by a single material layer; or the energy-absorbing colloid layer 23 can also be a multi-layer structure composed of multiple different materials. The embodiment of the present application does not limit this.

[0030] In the technical solution provided by the embodiment of the present application, the display screen 2 includes a display panel 21, a protective glass 22, and an energy-absorbing colloid layer 23. Among them, the display output area of the display panel 21 is used to display images, videos, or texts. The protective glass 22 covers the surface where the display output area is located to protect the display panel 21 and provide additional functional support. The energy-absorbing colloid layer 23 covers the protective glass 22. In this way, when the display screen 2 is impacted or dropped by an external force, on the one hand, the energy-absorbing colloid layer 23 can absorb the impact energy through its own elastic deformation, reducing the energy transmitted to the protective glass 22, thereby avoiding the breakage or fragmentation of the protective glass 22 caused by energy concentration. At the same time, the elastic characteristics of the energy-absorbing colloid layer 23 can also buffer the impact force and reduce the instantaneous impact strength on the protective glass 22. On the other hand, when the display screen 2 is impacted by an external force, the energy-absorbing colloid layer 23 and the protective glass 22 can deform cooperatively to evenly disperse the local impact force to a larger area, avoiding stress concentration at a certain point on the protective glass 22, thereby reducing the probability of the protective glass 22 breaking due to excessive local stress.

[0031] In the embodiment of the present application, the energy-absorbing colloid layer 23 and the protective glass 22 may be non-detachably connected. For example, the energy-absorbing colloid layer 23 may be directly formed on the protective glass 22 through an injection molding process; or, the energy-absorbing colloid layer 23 may be permanently bonded to the protective glass 22 through a hot pressing process. The embodiment of the present application does not limit this. When the energy-absorbing colloid layer 23 and the protective glass 22 are non-detachably connected, the energy-absorbing colloid layer 23 and the protective glass 22 can form an integrated structure, improving the overall strength and structural stability.

[0032] In a possible embodiment of the present application, the energy-absorbing colloid layer 23 and the protective glass 22 are detachably connected so that the energy-absorbing colloid layer 23 can be separated from the protective glass 22 after the energy-absorbing colloid layer 23 absorbs energy. Here, the energy-absorbing colloid layer 23 may generate microcracks inside after absorbing energy, and these microcracks will reduce the energy absorption performance and transparency of the energy-absorbing colloid layer 23. The energy-absorbing colloid layer 23 and the protective glass 22 are detachably connected. In this way, after the energy-absorbing colloid layer 23 absorbs energy, the energy-absorbing colloid layer 23 can be separated from the protective glass 22, and the energy-absorbing colloid layer 23 can be replaced separately to ensure that the energy-absorbing colloid layer 23 is always in the best state, thereby extending the service life of the display screen 2. In addition, replacing the energy-absorbing colloid layer 23 separately instead of replacing the entire display screen 2 can reduce the maintenance cost of the display screen 2.

[0033] In the embodiment of the present application, when the energy-absorbing colloid layer 23 and the protective glass 22 are detachably connected, there are various possible connection forms between the energy-absorbing colloid layer 23 and the protective glass 22. For example, referring to Figure 2, the energy-absorbing colloid layer 23 and the protective glass 22 can be connected by an adhesive 24, and a high water contact angle coating 223 is provided on at least one of the energy-absorbing colloid layer 23 and the protective glass 22 on the side facing the adhesive 24 to reduce the adhesion between the energy-absorbing colloid layer 23 and the protective glass 22 and avoid damaging the protective glass 22 when the energy-absorbing colloid layer 23 and the protective glass 22 are separated. It should be noted that the adhesive 24 here can be an optically clear adhesive (OCA), which can reduce the loss of light propagation in the adhesive 24, thereby improving the display effect of the display screen 2.

[0034] In the embodiments of the present application, the structural form of the energy-absorbing colloid layer 23 has various possibilities. For example, the energy-absorbing colloid layer 23 can be composed of a single silica gel layer. Refer to Figure 2 and Figure 3 , in a possible embodiment of the present application, along the thickness direction of the energy-absorbing colloid layer 23, the energy-absorbing colloid layer 23 includes a first layer 231, an energy-absorbing layer 232, and a second layer 233 that are sequentially stacked. In this way, the energy-absorbing colloid layer 23 can form a multi-layer structure, and each layer in the multi-layer structure can use the same or different materials to absorb impact energy layer by layer, so as to disperse the energy to multiple levels, avoid energy concentration, and improve the overall energy absorption efficiency. For example, the first layer 231 can be made of a high-elasticity material for absorbing the initial impact; the energy-absorbing layer 232 can be made of a high-damping material for dissipating energy; the second layer 233 can be made of a high-bonding material for enhancing the bonding with the protective glass 22. In addition, each layer in the multi-layer structure can also be optimized according to the frequency and intensity of the impact force. For example, the outer layer in the multi-layer structure should be able to handle high-frequency impacts, and the inner layer in the multi-layer structure should be able to handle low-frequency vibrations, so that the energy-absorbing colloid layer 23 can handle various types of impacts.

[0035] In the embodiments of the present application, there are various possibilities for the material selection of the first layer 231, and the embodiments of the present application do not limit this. For example, the first layer 231 can be a transparent polyimide (Colorless Polyimide, CPI) layer. Since the transparent polyimide has excellent flexibility and can withstand multiple bends without breaking, the first layer 231 can adapt to complex device shapes to provide uniform energy absorption and protection effects for the protective glass 22. Alternatively, the first layer 231 can also be a polyethylene terephthalate (Polyethylene Terephthalate, PET) layer. Since the polyethylene terephthalate has the characteristics of low cost and high transparency, in this way, the production cost of the first layer 231 can be reduced, and at the same time, the loss of light propagation in the first layer 231 can be reduced, thereby improving the display effect of the display screen 2.

[0036] In the embodiments of the present application, there are various possibilities for the material selection of the second layer 233, and the embodiments of the present application do not limit this. For example, the second layer 233 can be a transparent polyimide layer or a polyethylene terephthalate layer. Here, the material of the second layer 233 can be the same as or different from the material of the first layer 231, and the embodiments of the present application do not limit this either.

[0037] In the embodiments of the present application, when the second layer 233 is located on the side of the energy absorption layer 232 facing the protective glass 22, the hardness of the second layer 233 can be greater than that of the first layer 231. In this way, on the one hand, the second layer 233 can provide a solid support for the energy absorption layer 232, enabling it to undergo elastic deformation more effectively when subjected to impact, thereby absorbing more impact energy; on the other hand, the second layer 233 can effectively absorb and attenuate vibration energy, reducing the vibration transmitted to the protective glass 22 and the display panel 21.

[0038] In the embodiments of the present application, there are various possibilities for the material selection of the energy absorption layer 232. For example, the material of the energy absorption layer 232 can be polyurethane (PU), silicone, or epoxy resin. The embodiments of the present application do not limit this.

[0039] In the embodiments of the present application, there are various possibilities for the thickness design of the first layer 231, the second layer 233, and the energy absorption layer 232. For example, the thickness ranges of the first layer 231 and the second layer 233 can be 25 - 100 μm, and the thickness range of the energy absorption layer 232 can be 50 - 200 μm.

[0040] Referring to Figure 3 , in a possible embodiment of the present application, the interface layer of the first layer 231 for contacting the energy absorption layer 232 has a first microstructure 2311 to increase the connection force between the first layer 231 and the energy absorption layer 232; the interface layer of the second layer 233 for contacting the energy absorption layer 232 has a second microstructure 2331 to increase the connection force between the second layer 233 and the energy absorption layer 232. Here, the first layer 231 has the first microstructure 2311 for increasing the connection force between the first layer 231 and the energy absorption layer 232, and the second layer 233 has the second microstructure 2331 for increasing the connection force between the second layer 233 and the energy absorption layer 232. On the one hand, it can enable the energy absorption colloid layer 23 to more effectively transfer and disperse impact energy between its layers, improving the energy absorption efficiency of the energy absorption colloid layer 23; on the other hand, it can significantly improve the overall strength of the energy absorption colloid layer 23, making it less likely to deform or break when subjected to impact.

[0041] In the embodiments of the present application, the structural form of the first microstructure 2311 has various possibilities. For example, the first microstructure 2311 can be an adhesive, and the connection force between the first layer 231 and the energy-absorbing layer 232 is increased through the adhesive; alternatively, the first microstructure 2311 can be an activation layer. Here, the activation layer is formed by treating the surface of the first layer 231 with chemical reagents (such as acids, bases, oxidants) to introduce polar groups (such as hydroxyl groups, carboxyl groups, amino groups, etc.). The introduction of polar groups can increase the polarity of the corresponding side surface of the first layer 231, thereby increasing the connection force between the first layer 231 and the energy-absorbing layer 232. The activation layer can also increase the roughness of the corresponding side surface of the first layer 231, thereby increasing the contact points between the first layer 231 and the energy-absorbing layer 232, and further increasing the connection force between the first layer 231 and the energy-absorbing layer 232.

[0042] In the embodiments of the present application, the structural form of the second microstructure 2331 has various possibilities. For example, the second microstructure 2331 can be an adhesive or an activation layer, and the embodiments of the present application do not limit this. Here, the structural form of the second microstructure 2331 can be the same as that of the first microstructure 2311. In this way, the refractive index of the first microstructure 2311 and the refractive index of the second microstructure 2331 can be the same or similar, thereby reducing the scattering during the propagation of light between the first microstructure 2311 and the second microstructure 2331, which helps to improve the display quality of the display screen 2. Here, the refractive index refers to the ratio of the speed of light in a vacuum to the speed of light in a medium, and the refractive index determines the propagation direction and speed change of light in the medium. Alternatively, the structural form of the second microstructure 2331 can also be different from that of the first microstructure 2311. In this way, the first layer 231 and the second layer 233 increase the connection force with the energy-absorbing layer 232 in different ways, so that the first microstructure 2311 and the second microstructure 2331 can be designed for different types of impacts. For example, the first microstructure 2311 can use a high-elasticity material to absorb the initial impact, and the second microstructure 2331 can use a high-damping material to further dissipate the impact energy, so as to improve the energy-absorbing efficiency of the energy-absorbing colloid layer 23.

[0043] In a possible embodiment of the present application, the first microstructure 2311 is a first coating, the second microstructure 2331 is a second coating, and the first coating and the second coating are hydrophilic coatings. In this way, on the one hand, the hydrophilic coating can reduce the water contact angle on the corresponding sides of the first layer 231 and the second layer 233 to increase the surface energy on the corresponding sides of the first layer 231 and the second layer 233, thereby increasing the physical contact area between the first layer 231, the second layer 233 and the energy-absorbing layer 232, and thus enhancing the physical adsorption effect; on the other hand, the hydrophilic coating has high transparency and low haze, which can reduce the loss of light propagation in the first microstructure 2311 and the second microstructure 2331, thereby improving the display effect of the display screen 2.

[0044] In the embodiments of the present application, the refractive index of at least one of the first coating and the second coating is the same as that of the energy absorption layer 232. Here, the refractive index refers to the ratio of the speed of light in a vacuum to the speed of light in a medium. The refractive index determines the propagation direction and speed change of light in the medium. The refractive index of at least one of the first coating and the second coating being the same as that of the energy absorption layer 232 can reduce the scattering of light at the interface between the corresponding coating and the energy absorption layer 232, reduce the loss of light during propagation, and improve the display effect of the display screen 2.

[0045] In the embodiments of the present application, the refractive index of one of the first coating and the second coating is the same as that of the energy absorption layer 232. Alternatively, the refractive indices of both the first coating and the second coating can be the same as that of the energy absorption layer 232. In this way, the transparency of the energy absorption colloid layer 23 can be maximally improved, ensuring the high-definition effect of the display screen 2.

[0046] In the embodiments of the present application, the energy absorption layer 232 includes target fillers so that the light transmittance of the energy absorption colloid layer 23 and the light transmittance of the protective glass 22 meet target conditions. Here, the light transmittance refers to the ability of light to pass through a material. The higher the light transmittance, the smaller the blockage of light by the material, and the clearer the display effect.

[0047] In the embodiments of the present application, the target conditions may refer to the light transmittance of the energy absorption colloid layer 23 being equal to the light transmittance of the protective glass 22. Here, the equal light transmittance of the energy absorption colloid layer 23 and the protective glass 22 can minimize the propagation loss of light at the interface between the two, and at the same time can also avoid the reflection and scattering of light at the interface between the two, which is beneficial to improving the display clarity of the display screen 2. Alternatively, the target conditions may also refer to the light transmittance of the energy absorption colloid layer 23 being less than the light transmittance of the protective glass 22. The energy absorption colloid layer 23 with a lower light transmittance can usually be designed to be thicker, thereby increasing the energy absorption capacity of the energy absorption colloid layer 23, enabling the energy absorption colloid layer 23 to better absorb and disperse impact energy, and improving the impact resistance. In addition, the thicker energy absorption colloid layer 23 can enhance its own anti-bending performance and reduce the probability of bending deformation when subjected to external impact. Or, the target conditions may also refer to the light transmittance of the energy absorption colloid layer 23 being greater than the light transmittance of the protective glass 22. The energy absorption colloid layer 23 with a higher light transmittance can reduce the loss of light during propagation in the energy absorption colloid layer 23, thereby improving the display effect of the display screen 2.

[0048] In the embodiments of the present application, the material of the target fillers has various possibilities. For example, the target fillers can be nanoscale fillers such as polymethyl methacrylate, nano-silica, etc.; or the target fillers can also be plasticizers such as phthalates, polyethylene glycol, optical-grade epoxy resins, etc. The embodiments of the present application do not limit this.

[0049] In the embodiments of the present application, the display panel 21 may be a rigid display panel 21 or a flexible display panel 21, and the embodiments of the present application do not limit this. Refer to Figure 2 , in a possible embodiment of the present application, the display panel 21 has a deformable ability. The protective glass 22 includes at least two first parts 221 and a second part 222 located between the two first parts 221. The thickness of the first part 221 is greater than the thickness of the second part 222, so that the deformable ability of the second part 222 is greater than that of the first part 221. Here, the display panel 21 having a deformable ability can make the form of the display surface of the electronic device no longer limited to a plane, and can enable the display surface of the electronic device to achieve various designs such as a curved surface, folding, and curling, improving the flexibility of the design of the electronic device. The protective glass 22 includes at least two first parts 221 and a second part 222 located between the two first parts 221. The thickness of the first part 221 is greater than the thickness of the second part 222, so that the deformable ability of the second part 222 is greater than that of the first part 221. In this way, in the application of the display screen 2, the first part 221 of the protective glass 22 can be arranged corresponding to the non-deformable area or the area with a weak deformable ability of the display panel 21, and the second part 222 of the protective glass 22 can be arranged corresponding to the area with a strong deformable ability of the display panel 21. The display panel 21 usually completes deformation through the area with a strong deformable ability. At this time, the second part 222 of the protective glass 22 can follow the deformation area of the display panel 21 to complete deformation, so that the protective glass 22 is always attached to the surface of the display panel 21, thereby improving the protection effect of the protective glass 22 on the display panel 21. In addition, the protective glass 22 makes the deformable ability of the second part 222 greater than that of the first part 221 through an unequal thickness design. In this way, the protective glass 22 can maintain a relatively thick thickness in the non-deformable area, thereby improving the overall structural strength of the protective glass 22.

[0050] Refer to Figure 2, in the embodiments of the present application, there is a filling 25 between the second part 222 and the display panel 21, and the refractive index of the filling 25 is the same as or close to that of the protective glass 22. Since the thickness of the first part 221 is greater than that of the second part 222, when the protective glass 22 covers the display panel 21, there may be a gap between the second part 222 and the display panel 21. The setting of the filling 25 can, on the one hand, prevent an air gap from being formed between the second part 222 and the display panel 21, thereby avoiding light scattering when passing through the air layer and improving the display effect of the display screen 2; on the other hand, the filling 25 can closely combine the second part 222 with the display panel 21 and improve the impact resistance at the second part 222. The refractive index of the filling 25 is the same as or close to that of the protective glass 22, so that light scattering during the propagation between the filling 25 and the protective glass 22 can be reduced, which helps to improve the display quality of the display screen 2.

[0051] In the embodiments of the present application, the material of the filling 25 can be the same as that of the energy-absorbing layer 232. In this way, on the one hand, the elastic moduli of the two can be matched, so that the two can cooperate to absorb impact energy and improve the protection effect on the protective glass 22; on the other hand, the refractive index of the filling 25 can be the same as or close to that of the energy-absorbing layer 232, thereby reducing light scattering during the propagation between the filling 25 and the energy-absorbing layer 232, which helps to improve the display quality of the display screen 2.

[0052] On this basis, referring to Figure 1 and Figure 2 , the embodiments of the present application further provide an electronic device, which includes a housing 1 and a display screen 2. The display screen 2 is disposed in the housing 1, and the display screen 2 has a target display area 26 that constitutes the target surface of the housing. The display screen 2 includes a display panel 21, a protective glass 22, and an energy-absorbing colloid layer 23. The protective glass 22 covers the surface where the display output area of the display panel 21 is located, and the energy-absorbing colloid layer 23 covers the protective glass 22 and is used to absorb the energy of external impacts to protect the protective glass 22.

[0053] It should be noted that the electronic device mentioned in the embodiments of the present application can be a notebook computer, a foldable mobile phone, or a game console. The embodiments of the present application do not limit this. In one implementable manner provided by the embodiments of the present application, the electronic device is a foldable mobile phone.
