Description

Screens and electronic devices

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on June 14, 2023, with application number 202310708888.3 and application name “Screen and Electronic Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the technical field of display devices, and in particular to a screen and an electronic device. Background Art

[0003] Electronic devices (such as laptops and mobile phones) can include a screen and a front-facing camera. The screen is used to display images, and the front-facing camera is used to capture the scene in front of the screen. In order to achieve a larger screen-to-body ratio, more and more electronic devices place the front-facing camera below the screen, forming an under-screen camera structure.

[0004] Currently, there are generally two solutions for under-screen camera structures: the first solution is to keep the screen structure intact, with part of the screen forming a light-transmitting area, and the front camera placed below the light-transmitting area. In this solution, because the light-transmitting area of ​​the screen retains all the layers of the screen and is relatively thick, the light transmittance of the light-transmitting area is low, resulting in dark shooting effects and poor image quality from the front camera. The second solution is to dig a light hole in the screen and place the front camera below the light hole. In this solution, although the front camera collects light in front of the screen through the light hole and can obtain better image quality, the provision of the light hole will lead to a decrease in the structural strength of the screen. In particular, for bendable flexible screens, the structural strength of the screen at and around the light hole is significantly reduced, and the screen is easily damaged when pressed or impacted by external force, resulting in poor screen reliability.

[0005] Therefore, how to obtain a high-transmittance area on the screen with high reliability has become an urgent problem that needs to be solved.

[0006] Summary of the Invention

[0007] Embodiments of the present application provide a screen and an electronic device. The screen has an area with high light transmittance and high reliability.

[0008] In a first aspect, embodiments of the present application provide a screen that can be used in an electronic device, the electronic device including an optical device located on the non-display side of the screen. The screen includes a display screen and a reinforcement plate. The display screen includes a first screen portion and a second screen portion, the second screen portion surrounding or semi-surrounding the first screen portion. The second screen portion is connected to the first screen portion. The first and second screen portions can be integrally formed structural components.

[0009] The first screen portion includes a first outer surface and a first inner surface disposed opposite to each other, and the second screen portion includes a second outer surface and a second inner surface disposed opposite to each other, wherein the first outer surface is flush with the second outer surface, and the first inner surface is recessed relative to the second inner surface to form a groove. The thickness of the first screen portion is less than that of the second screen portion.

[0010] The second portion of the display screen is used to display images. The second portion of the display screen can have a conventional display structure, which corresponds to a fully laminated structure of the display screen. The first portion of the display screen can have fewer layers and a smaller thickness by reducing some layers and retaining some layers relative to the second portion.

[0011] The reinforcing plate is located on the side of the first inner surface facing away from the first outer surface and is stacked with the first screen portion. The reinforcing plate is at least partially located within the groove and fixedly connected to the display screen. At least a portion of the first screen portion allows the passage of external light, and at least a portion of the reinforcing plate allows the passage of external light. External light can pass through the first screen portion and the reinforcing plate and enter the non-display side space of the screen.

[0012] The area of ​​the first screen portion that allows external light to pass through is referred to as the light-transmitting area of ​​the first screen portion. The area of ​​the reinforcing plate that allows external light to pass through is referred to as the light-transmitting area of ​​the reinforcing plate. In some implementations, the light-transmitting area of ​​the reinforcing plate is positioned directly opposite the light-transmitting area of ​​the first screen portion, with an overlapping area along the thickness of the screen. External light sequentially passes through the light-transmitting area of ​​the first screen portion and the light-transmitting area of ​​the reinforcing plate to enter the non-display side space of the screen.

[0013] In the embodiment of the present application, the light-transmitting area of ​​the screen is arranged to correspond to the light-transmitting area of ​​the first screen portion and the light-transmitting area of ​​the reinforcing plate to obtain a higher light transmittance. Since the reinforcing plate is stacked with the first screen portion, the reinforcing plate can enhance the structural strength of the first screen portion, thereby improving the structural strength of the display screen at the groove. When the screen is subjected to external pressure, extrusion or impact, the risk of deformation or damage is small, and the screen has higher reliability. In addition, since the reinforcing plate is at least partially located in the groove, the gap between the reinforcing plate and the first screen portion is small. When the first screen portion is squeezed or pressed, the deformation space in the thickness direction of the screen is small, so that the reinforcing plate has a better reinforcing effect on the first screen portion.

[0014] Among them, in the thickness direction of the screen, the light-transmitting area of ​​the first screen part completely covers the light-transmitting area of ​​the screen, and the light-transmitting area of ​​the reinforcement plate completely covers the light-transmitting area of ​​the screen, so that the light-transmitting area of ​​the screen as a whole has a higher light transmittance, and the optical path environment is consistent or similar, so that the lighting quality of the optical device located below the light-transmitting area of ​​the screen is better.

[0015] In some embodiments, the first screen portion of the display screen may have one or more layers, and most or all of the layers of the first screen portion may be layers with a higher light transmittance. In this case, the higher light transmittance of the first screen portion results in a higher light transmittance in the light-transmitting area of ​​the screen, thereby facilitating improved lighting quality for optical devices of the electronic device. Exemplarily, the light transmittance of all or most of the layers of the first screen portion may be greater than or equal to 20%, such as 45%, 68%, 80%, 85%, 91%, 93%, 98%, and the like.

[0016] In some possible implementations, the display screen includes a first stack and a second stack, with the first stack located in the first screen portion and the second screen portion, and the second stack located in the second screen portion. The first stack has a higher light transmittance than the second stack. That is, the first screen portion retains the first stack with a higher light transmittance relative to the second screen portion, while reducing the second stack with a lower light transmittance. For example, the light transmittance of the first stack is greater than 20%, while the light transmittance of the second stack is less than 20%.

[0017] In this embodiment, the first screen portion reduces low-transmittance layers while retaining high-transmittance layers, thereby improving overall transmittance. The first layer is one of the layers retained by the first screen portion, and the second layer is one of the layers reduced from the first screen portion relative to the second screen portion. This embodiment of the application does not limit the number of layers reduced from the first screen portion relative to the second screen portion to being entirely low-transmittance layers; it may also include some high-transmittance layers. It also does not limit the number of layers in the first screen portion to being entirely high-transmittance layers; it also allows the first screen portion to include low-transmittance layers for other functions.

[0018] In some possible implementations, the reinforcing plate has a higher light transmittance than the second stack. For example, the light transmittance of the region of the reinforcing plate that allows ambient light to pass through is higher than the light transmittance of the second stack. In this embodiment, the light transmittance of the reinforcing plate is higher than the light transmittance of the stacked layer reduced by the first screen portion, resulting in a higher overall light transmittance of the stacked structure of the first screen portion and the reinforcing plate than the light transmittance of the second screen portion. The light-transmitting region within this stacked structure has a higher light transmittance, which helps improve the lighting quality of the optical device.

[0019] In some embodiments, the reinforcing plate is a flat plate. It includes a first plate surface, a second plate surface, and a peripheral side surface. The first plate surface and the second plate surface are disposed opposite and parallel to each other, and the peripheral side surface circumferentially connects the first and second plate surfaces. The first plate surface of the reinforcing plate faces the first screen portion, while the second plate surface faces away from the first screen portion. In this embodiment, the reinforcing plate has a simple structure, is easy to manufacture, and is relatively low in cost.

[0020] Exemplarily, the reinforcing plate is parallel to the first screen portion. Specifically, the first and second surfaces of the reinforcing plate are both parallel to the first outer surface of the first screen portion. In this case, external light is less distorted as it passes through the first screen portion and the reinforcing plate, allowing the optical device to capture high-quality external light through the light-transmitting area of ​​the screen. For example, if the optical device is a camera module, the camera module can capture higher-quality images.

[0021] Exemplarily, the main structure of the reinforcement plate is a plate body. The plate body of the reinforcement plate can be made of a material with high light transmittance and high structural strength. The light transmittance of the plate body of the reinforcement plate can be adjusted according to the lighting requirements of the optical device. Exemplarily, the light transmittance of the plate body of the reinforcement plate is greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc. In some examples, the light transmittance of the plate body of the reinforcement plate can be greater than or equal to 80%, which is beneficial for external light to pass through the light-transmitting area of ​​the screen to increase the amount of light received by the camera module, so that the imaging quality of the camera module is higher and the risk of stray light and ghosting is reduced.

[0022] Exemplarily, the plate body of the reinforcing plate can be made of polymer material or optical glass. For example, the material of the plate body of the reinforcing plate can be transparent plastic, such as polyethylene terephthalate material, polycarbonate material, transparent polyimide material, cycloolefin polymer material, triacetate cellulose material, etc., or the material of the plate body of the reinforcing plate can be ultra-thin glass.

[0023] In some possible implementations, in the plane direction of the screen, the opening area of ​​the groove is a first area, the portion of the reinforcement plate located in the groove has a second area, and the ratio of the second area to the first area is greater than or equal to 80%.

[0024] In this embodiment, because the ratio of the area of ​​the reinforcement plate located within the groove to the area of ​​the groove opening is greater than or equal to 80%, the area of ​​the reinforcement plate located within the groove is larger, thereby better supporting the first screen portion and improving the reliability of the screen. Furthermore, the larger area of ​​the reinforcement plate helps ensure that all external light entering the non-display space of the screen through the light-transmitting area of ​​the screen can pass through the reinforcement plate, maintaining a consistent or similar optical path environment. This reduces the risk of image distortion in the optical device and improves the lighting quality of the optical device.

[0025] In some possible implementations, the screen further includes an adhesive member, which is located between the reinforcement plate and the first inner surface and fixedly connects the reinforcement plate and the first inner surface, and the adhesive member allows external light to pass through. In this case, the adhesive member is fixedly connected to the first plate surface of the reinforcement plate. The reinforcement plate is fixed to the first inner surface of the first screen portion in a stacked manner. The reinforcement plate can directly reinforce the first screen portion, and the reinforcement effect is good. In addition, the reinforcement plate and the first screen portion are compactly arranged, which is also conducive to controlling the thickness of the light-transmitting area of ​​the screen. When the position of the optical device is the bottleneck of the overall thickness of the electronic device, the overall thickness of the electronic device can be effectively controlled, which is conducive to achieving thinness of the electronic device.

[0026] The adhesive can be made of a material with high light transmittance. For example, the light transmittance of the adhesive can be greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc. In some examples, the light transmittance of the adhesive is greater than or equal to 80%. For example, the adhesive can be transparent optical adhesive or pressure-sensitive adhesive.

[0027] In some possible implementations, the surface of the second screen portion facing the groove is a side wall of the groove, and a gap is formed between the peripheral side surface of the reinforcement plate and the side wall of the groove.

[0028] In this embodiment, the gap between the peripheral side surface of the reinforcement plate and the side wall of the groove is an assembly gap. By providing the assembly gap, the risk of damage to the display screen caused by the reinforcement plate can be reduced, thereby protecting the display screen.

[0029] In some possible implementations, the display screen includes a light-shielding layer, which is annular. The light-shielding layer is at least partially located in the first screen portion. In the thickness direction of the screen, the light-shielding layer covers the gap and the periphery of the reinforcing plate, while exposing the center of the reinforcing plate. The light-shielding layer can be made of a light-absorbing material or a light-blocking material. For example, the light-shielding layer can be an ink layer.

[0030] In this embodiment, the light-shielding layer shields the gap between the reinforcing plate and the sidewalls of the groove, as well as the periphery of the reinforcing plate, thereby improving the appearance of the screen. The light-shielding layer also absorbs stray light, reducing the amount of stray light that enters the light path of the optical device, thereby improving the lighting quality of the optical device. The stray light may include, but is not limited to, light emitted by the display screen or light emitted by components such as the flash within the electronic device.

[0031] In some possible implementations, the reinforcement plate includes a plate body and a light-blocking layer. The light-blocking layer is fixed to the surface of the plate body facing away from the first screen portion. The light transmittance of the plate body is greater than or equal to 20%. The light-blocking layer can be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer can be an ink layer, which can be formed by directly applying ink to the surface of the plate body. Alternatively, the light-blocking layer can be a black film, which can be fixed to the surface of the plate body by bonding or other methods.

[0032] The light blocking layer is annular, the inner diameter of the light blocking layer is smaller than the inner diameter of the light shielding layer, the outer diameter of the light blocking layer is larger than the inner diameter of the light shielding layer, and the inner ring space of the light blocking layer faces the inner ring space of the light shielding layer.

[0033] In this embodiment, since the surface of the reinforcement plate facing away from the first screen portion is close to the non-display side of the screen, it is also close to the optical device located on the non-display side of the screen. Therefore, the distance between the light blocking layer located on the surface of the plate body facing away from the first screen portion and the optical device is small. Based on the field of view characteristics of the optical device for collecting light, the inner diameter of the light blocking layer can be set to a smaller size, and then the outer diameter of the light blocking layer can be smaller, the outer diameter of the reinforcement plate can be smaller, and the opening size of the groove of the display screen can be smaller, which is beneficial to reducing the area of ​​the non-display area of ​​the screen and increasing the screen-to-body ratio of the screen.

[0034] The light-shielding layer can block the gap between the reinforcing plate and the side wall of the groove, thereby blocking the light-blocking structure step difference such as the ink step difference at the edge of the reinforcing plate, thereby improving the appearance of the screen.

[0035] In some possible implementations, the reinforcement plate includes a plate body and a light-blocking layer, with the light-blocking layer covering the peripheral side surfaces of the plate body. The light-blocking layer can be made of a light-absorbing or light-blocking material to block the light path. For example, the light-blocking layer can be an ink layer, which can be formed by directly applying ink to the peripheral side surfaces of the plate body. Alternatively, the light-blocking layer can be a black film, which can be fixed to the peripheral side surfaces of the plate body by adhesive bonding or other means.

[0036] In this embodiment, the light-blocking layer of the reinforcement plate is positioned facing the sidewalls of the groove. The light-blocking layer absorbs or blocks the propagation of stray light, thereby reducing the amount of stray light entering the light path of the optical device, lowering the risk of crosstalk, and improving the light quality of the optical device. The stray light may be, but is not limited to, light emitted by a display screen or components such as a flash within an electronic device.

[0037] In some possible implementations, the sum of the thickness of the reinforcing plate and the thickness of the adhesive along the thickness direction of the screen is equal to the depth of the groove. In this case, the second surface of the reinforcing plate is flush with the second inner surface of the second screen portion. The reinforcing plate does not increase the thickness of the screen, thereby contributing to a thinner electronic device. Furthermore, it can also make the inner surface of the screen smooth, which helps to reduce the difficulty of screen assembly and simplify the screen assembly structure.

[0038] In some possible implementations, the sum of the thickness of the reinforcing plate and the thickness of the adhesive in the thickness direction of the screen is less than the depth of the groove. In this case, the second surface of the reinforcing plate is recessed relative to the second inner surface of the second screen portion. The provision of the reinforcing plate does not increase the thickness of the screen, thereby facilitating a thinner electronic device.

[0039] In some possible implementations, the reinforcement plate includes a first plate and a second plate, with the second plate being fixed to the middle portion of the first plate. The first plate is a portion of the plate, and the second plate is another portion of the plate. The first and second plates may be stacked. The first and second plates may be integrally formed components. The light transmittance of the first and second plates is greater than or equal to 20%.

[0040] The second plate is at least partially located in the groove, the first plate is located outside the groove, and the periphery of the first plate is fixedly connected to the second screen portion. For example, the periphery of the first plate can be bonded to the second screen portion via an adhesive layer.

[0041] In this embodiment, the light-transmitting area of ​​the screen can be arranged corresponding to the first screen portion, the middle portion of the first plate, and the middle portion of the second plate. The light-transmitting area has a high light transmittance, so as to facilitate lighting for the optical devices located on the non-display side of the screen. Because the first and second plates are stacked with the first screen portion, and the second plate is at least partially located within the groove, the reinforcement plate can increase the structural strength of the first screen portion and its surroundings, thereby improving the structural reliability of the screen. In addition, because the reinforcement plate is fixedly connected to the second screen portion and the second screen portion is thicker, the second screen portion can provide a more reliable fixing structure and support force, making the assembly structure of the reinforcement plate and the display screen more stable and reliable.

[0042] In some examples, the light transmittance of the reinforcement plate can be greater than or equal to 80%, thereby facilitating the passage of external light through the light-transmitting area of ​​the screen, thereby increasing the amount of light received by the camera module, improving imaging quality, and reducing the risk of stray light and ghosting. The first and second plates can be made of polymer materials or optical glass.

[0043] In some possible implementations, the surface of the second screen portion facing the recess serves as the recess's sidewall, and a gap is formed between the peripheral side surface of the second plate and the recess's sidewall. In this embodiment, the gap between the peripheral side surface of the second plate and the recess's sidewall serves as an assembly gap. Providing this assembly gap reduces the risk of damage to the display screen from the reinforcement plate, thereby protecting the display screen.

[0044] The reinforcement plate further includes a light-blocking layer, which is annular in shape. The light-blocking layer is fixed to the periphery of the surface of the first plate body facing away from the second plate body. In the thickness direction of the screen, the light-blocking layer covers the gap and the periphery of the second plate body. The light-blocking layer can be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer can be an ink layer, which can be formed by directly applying ink to the second plate surface. Alternatively, the light-blocking layer can be a black film, which can be fixed to the second plate surface by bonding or other means.

[0045] In this embodiment, the light-blocking layer shields the gap between the reinforcing plate and the sidewalls of the groove, as well as the periphery of the second plate, thereby improving the appearance of the screen. Furthermore, the light-blocking layer absorbs stray light, reducing the amount of stray light that enters the light path of the optical device, thereby improving the light quality of the optical device. The stray light may be, but is not limited to, light emitted by the display screen or light emitted by components such as a flash within the electronic device.

[0046] In addition, the light-blocking layer is fixed to the periphery of the surface of the first plate body facing away from the second plate body. The light-blocking layer is close to the non-display side of the screen, and therefore is also close to the optical device located on the non-display side of the screen. Therefore, the distance between the light-blocking layer and the optical device is small. Based on the field of view characteristics of the optical device for collecting light, the inner diameter of the light-blocking layer can be set to a smaller size, and then the outer diameter of the light-blocking layer can be smaller, the outer diameter of the reinforcement plate can be smaller, and the opening size of the groove of the display screen can be smaller, which is beneficial to increase the screen-to-body ratio of the screen.

[0047] In some possible implementations, the reinforcing plate further includes a light-blocking layer, which covers at least the area of ​​the peripheral side surface of the second plate body located within the groove. For example, the light-blocking layer may cover the peripheral side surface of the second plate body. The light-blocking layer may be made of a light-absorbing or light-blocking material to block the light path. For example, the light-blocking layer may be an ink layer, which may be formed by directly applying ink to the peripheral side surface of the second plate body. Alternatively, the light-blocking layer may be a black film, which may be secured to the peripheral side surface of the second plate body by adhesive bonding or other means.

[0048] In this embodiment, the light-blocking layer of the reinforcement plate is positioned facing the sidewalls of the groove. The light-blocking layer absorbs or blocks the propagation of stray light, thereby reducing the amount of stray light entering the light path of the optical device, lowering the risk of crosstalk, and improving the light quality of the optical device. The stray light may be, but is not limited to, light emitted by a display screen or components such as a flash within an electronic device.

[0049] In some possible implementations, the reinforcing plate may include a light-transmitting portion and a light-shielding portion, wherein the light-transmitting portion has a higher light transmittance than the light-shielding portion. The light-transmitting portion is configured to allow external light to pass through, while the light-shielding portion is configured to block external light. The light-shielding portion is disposed around the light-transmitting portion and is fixed to a peripheral side surface of the light-transmitting portion.

[0050] The light-shielding portion may have a light transmittance of less than 20%, and the light-transmitting portion may have a light transmittance greater than or equal to 20%. The light-shielding portion and the light-transmitting portion may be integrally formed components, for example, by two-color injection molding or other processes.

[0051] In some embodiments, the light shielding portion can also absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device and improving the lighting quality of the optical device.

[0052] In a second aspect, embodiments of the present application further provide an electronic device comprising a housing, an optical device, and any of the aforementioned screens. The screen is mounted within the housing, and the optical device is mounted within the housing and positioned on the non-display side of the screen, the optical device being configured to collect external light that passes through the first screen portion and the reinforcement plate.

[0053] In this embodiment, the screen's light-transmitting area has high light transmittance, resulting in high-quality imaging from the camera module. The screen's reinforcement plate increases the structural strength of the first screen portion, minimizing the risk of deformation or damage when subjected to external pressure or impact. This also reduces the risk of damage to optical components, thereby improving the reliability of the electronic device.

[0054] In some possible implementations, the electronic device further includes a support member, which is abutted between the reinforcing plate and the housing.

[0055] In this embodiment, since the support member is in contact between the reinforcing plate and the shell, the shell can indirectly support the reinforcing plate through the support member, and then support the first screen portion, so that the risk of deformation or damage of the first screen portion when subjected to external pressure or impact is further reduced, and the screen and electronic device have higher reliability.

[0056] The support member can be made of an elastic material to provide support and cushioning functions. For example, the support member can be made of foam, glue, tape, etc. In this case, the support member can also absorb assembly tolerances between the screen and the housing during the assembly process of the electronic device, thereby improving the yield of the electronic device. The thickness of the support member can be in the range of 0.1mm to 0.2mm.

[0057] In some possible implementations, the support member is disposed around the collection surface of the optical device. For example, the support member may be roughly annular. In this embodiment, since the support member is disposed around the incident surface of the optical device, the provision of the support member does not affect the lighting of the optical device. Furthermore, the support area of ​​the support member for the reinforcement plate is annular, and the support area is relatively evenly distributed around the periphery of the reinforcement plate, making it less likely for the reinforcement plate to tilt or warp. This ensures the consistency of the light path of the light-transmitting area of ​​the screen while reinforcing the first screen portion.

[0058] In some possible implementations, a support member surrounds the optical device's collection surface and seals the reinforcement plate to the housing. In this case, the support member seals the gap between the housing and the reinforcement plate, thereby sealing the gap between the optical device and the reinforcement plate. This reduces the risk of dust entering the optical device's incident surface, achieving dust protection.

[0059] In some possible implementations, the support member abuts between the second screen portion and the housing. In this case, the housing can indirectly support the second screen portion through the support member, further reducing the risk of deformation or damage to the screen when subjected to external pressure or impact, thereby improving the reliability of the screen and electronic device.

[0085] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings.

[0086] In the description of the embodiments of the present application, unless otherwise expressly specified and limited, "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent three situations: A exists alone, A and B exist at the same time, and B exists alone. The terms "first" and "second" are used for descriptive purposes only and cannot be understood as implying or suggesting the relative importance or the number of implicitly specified technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. "Multiple" refers to two or more than two.

[0087] The terms "installation" and "connection" should be understood broadly. For example, "connection" can be detachable or non-detachable, and can be direct or indirect through an intermediary. An "integrally formed structural component" refers to a component in which one portion is immediately connected to the rest of the component during the formation process, without requiring further processing (such as bonding, welding, or clamping) to connect to the other portions.

[0088] The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "inner", "outer", etc., are only references to the directions in the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0089] An embodiment of the present application provides a screen and an electronic device including the screen. The screen includes a display screen and a reinforcement plate. The display screen includes a first screen portion and a second screen portion, and the second screen portion surrounds or semi-surrounds the first screen portion. The thickness of the first screen portion is smaller than that of the second screen portion, and the inner side of the first screen portion is recessed relative to the second screen portion to form a groove. The reinforcement plate is stacked with the first screen portion of the display screen, and the reinforcement plate is at least partially located in the groove. At least a portion of the first screen portion allows external light to pass through, and at least a portion of the reinforcement plate allows external light to pass through. External light can pass through the first screen portion and the reinforcement plate and enter the non-display side space of the screen.

[0090] In this embodiment of the present application, the screen's light-transmitting area corresponds to the first screen portion of the display screen and the portion of the reinforcement plate that allows ambient light to pass through, exhibiting high light transmittance. Furthermore, the reinforcement plate enhances the structural strength of the display screen at the recessed portion, thereby improving the screen's reliability. Therefore, the screen of this embodiment of the present application, while having a light-transmitting area with high light transmittance, can achieve high reliability.

[0091] Among them, electronic devices can be mobile phones, laptops, tablets, wearable devices and other electronic products with display functions, and wearable devices can be smart watches, smart bracelets, smart glasses, etc.

[0092] FIG1 is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of the present application when it is in a fully open state, FIG2 is a schematic diagram of the structure of the electronic device 100 shown in FIG1 when it is in a partially open state, and FIG3 is a schematic diagram of the structure of the electronic device 100 shown in FIG1 when it is in a closed state. The electronic device 100 in the embodiment of the present application is described by taking a foldable mobile phone as an example. Of course, other types of electronic devices can also adopt similar structures, which will not be described in detail below. It should be noted that FIG1 and the related drawings below only schematically illustrate some components included in the electronic device 100, and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG1 and the drawings below.

[0093] In some embodiments, as shown in Figures 1 to 3, the electronic device 100 may include a screen 10 and a housing 20. Exemplarily, the housing 20 may include a first housing portion 201, a second housing portion 202, and a hinge (not shown in the figure), which connects the first housing portion 201 and the second housing portion 202. Through the movement of the hinge, the first housing portion 201 and the second housing portion 202 can be relatively unfolded to a fully open state or relatively folded to a closed state, and can also be relatively unfolded or relatively folded to a partially open state. Among them, the first housing portion 201 may include a first middle frame, and the second housing portion 202 may include a second middle frame. In some examples, the first housing portion 201 may further include a first back cover, which may be fixedly connected to the side of the first middle frame facing away from the screen 10; the second housing portion 202 may further include a second back cover, which may be fixedly connected to the side of the second middle frame facing away from the screen 10.

[0094] Exemplarily, the screen 10 is mounted on the housing 20. The screen 10 has a display function, or the screen 10 can integrate a display function and a touch sensing function. The display function of the screen 10 is used to display text, images, videos, etc. The touch sensing function of the screen 10 is used to detect the user's touch action to achieve information interaction between man and machine. The screen 10 has a display side and a non-display side arranged opposite to each other, and the display side of the screen 10 is the side from which the screen 10 emits light to achieve display. In this embodiment, the display side of the screen 10 faces the outside of the electronic device 100, and the non-display side of the screen 10 faces the inside of the electronic device 100.

[0095] The screen 10 may be a flexible, bendable screen that deforms with the housing 20. For example, the screen 10 may include a first portion 101, a second portion 102, and a third portion 103, with the third portion 103 connected between the first portion 101 and the second portion 102. Specifically, the first portion 101, the third portion 103, and the second portion 102 are arranged sequentially. The first portion 101 may be fixed to the first housing 201, and the second portion 102 may be fixed to the second housing 202. During relative expansion or folding of the first and second housings 201, 202, the first housing 201 drives the first portion 101 to move, and the second housing 202 drives the second portion 102 to move. The third portion 103 deforms under the influence of the first portion 101, the second portion 102, and the housing 20.

[0096] As shown in FIG1 , the first shell portion 201 and the second shell portion 202 can be unfolded relative to each other to a fully open state. The housing 20 and the electronic device 100 are both in the fully open state, and the screen 10 unfolds along with the housing 20. For example, when the housing 20 is in the fully open state, the angle between the first shell portion 201 and the second shell portion 202 is 100°, 120°, 150°, 165°, 180°, etc. The embodiment of the present application is described using the angle between the first shell portion 201 and the second shell portion 202 being 180° as an example. At this time, the screen 10 is in a flattened state, and the first portion 101, the third portion 103, and the second portion 102 of the screen 10 are located in the same plane.

[0097] As shown in Figure 3, the first shell portion 201 and the second shell portion 202 can be folded relative to each other into a closed position, so that both the housing 20 and the electronic device 100 are in a closed position, and the screen 10 folds along with the housing 20. For example, when the housing 20 is in the closed position, the screen 10 can be located between the first shell portion 201 and the second shell portion 202, that is, the screen 10 can be enclosed by the housing 20. In Figure 3, the screen 10 is not shown because it is obscured by the housing 20. It will be understood that when the first shell portion 201 and the second shell portion 202 are in the closed position, the angle between the first shell portion 201 and the second shell portion 202 can be approximately 0°. When the screen 10 is in the closed position, the first portion 101 and the second portion 102 of the screen 10 are arranged opposite each other, and the two portions can partially abut each other, fully abut each other, or there is a small gap between them. The third portion 103 is in a fully bent position.

[0098] As shown in Figure 2, the first shell portion 201 and the second shell portion 202 can also be relatively unfolded or folded to a partially open state, so that both the housing 20 and the electronic device 100 are in a partially open state. The partially open state can be any state between the fully open state and the closed state, and the screen 10 will also change accordingly. When the screen 10 is in the partially open state, the first portion 101 and the second portion 102 of the screen 10 form an angle, and the third portion 103 of the screen 10 is partially bent.

[0099] In this embodiment, the screen 10 can be unfolded or folded along with the housing 20. When the electronic device 100 is fully opened, the screen 10 is flattened and can display full-screen content, providing the electronic device 100 with a larger display area and improving the user's viewing and operating experience. When the electronic device 100 is closed, the electronic device 100 has a small planar size, making it easier for the user to carry and store. When the electronic device 100 is partially opened, a portion of the screen 10 is bent to meet the user's viewing needs at different viewing angles.

[0100] In some embodiments, as shown in Figures 1 and 2, the electronic device 100 may further include an optical device 30, which is mounted on the housing 20. The optical device 30 may be located on the non-display side of the screen 10, and is used to collect external light passing through the screen 10. In an embodiment of the present application, by arranging the optical device 30 below the screen 10, an under-screen lighting structure is formed, so that the screen 10 can have a larger display area to obtain a higher screen-to-body ratio. The external light refers to the light outside the electronic device 100. For example, the external light may include light propagating outside the electronic device 100. In some embodiments, the external light may also include light emitted by the electronic device 100 and reflected or refracted by a structure or environment outside the electronic device 100.

[0101] Exemplarily, the optical device 30 may be a camera module. The screen 10 is provided with a light-transmitting area 10a that allows external light to pass through, and the light-transmitting area 10a may be located in the first portion 101 of the screen 10. In some examples, the camera module may be mounted on the first shell portion 201, and the camera module is located on the non-display side of the first portion 101 of the screen 10, and is arranged opposite the light-transmitting area 10a of the screen 10. The camera module is used to collect external light passing through the light-transmitting area 10a of the screen 10 to achieve imaging. Among them, the end of the first shell portion 201 away from the second shell portion 202 is the top of the first shell portion 201, and the camera module can be installed in the middle position or at two corners of the top of the first shell portion 201. The light-transmitting area 10a of the screen 10 changes with the position of the camera module.

[0102] In some other embodiments, the optical device 30 may also be an ambient light sensor, a proximity light sensor, or an optical fingerprint sensor. When the optical device 30 is an optical fingerprint sensor, the fingerprint sensor may also be mounted on the second shell portion 202 of the housing 20, and the light-transmitting area 10a of the screen 10 may be located in the second portion 102 of the screen 10. The embodiments of the present application do not strictly limit the specific type of the optical device 30 or the specific location of the light-transmitting area 10a. In some other embodiments, the optical device 30 may also be an active light-emitting device such as a laser or an infrared remote control lamp (e.g., an infrared light-emitting diode lamp).

[0103] In the embodiment of the present application, the optical effect (e.g., transmittance, haze, etc.) of the light-transmitting area 10a of the screen 10 affects the lighting quality of the optical device 30, and thus affects the functional realization of the optical device 30. For example, when the optical device 30 is a camera module, high lighting quality means high imaging quality. When the optical device 30 is a detection module such as an ambient light sensor, a proximity light sensor, or an optical fingerprint sensor, high lighting quality means high detection accuracy. Transmittance is the percentage of the luminous flux passing through a transparent or translucent body to its incident luminous flux. Haze is the percentage of the transmitted light intensity that deviates from the incident light by more than 2.5° to the total transmitted light intensity. A greater haze means a decrease in the gloss and transparency of the film, especially the imaging quality. Generally, the higher the transmittance, the lower the haze. Therefore, in the embodiment of the present application, the light-transmitting area 10a of the screen 10 is configured to have a structure with a higher light transmittance to improve the lighting quality of the optical device 30 and facilitate the functional realization of the optical device 30.

[0104] In some embodiments, the electronic device 100 may further include multiple components (not shown in the figure), which are mainly housed inside the first shell 201 and the second shell 202, and some components may also be at least partially installed on the rotating shaft. This embodiment of the present application does not strictly limit this. The multiple components of the electronic device 100 may include but are not limited to a processor, an internal processor, an external storage interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera module, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, a subscriber identification module (SIM) card interface, one or more rigid circuit boards or flexible circuit boards, etc. Among them, the electronic device 100 may have more or fewer components than described above, may combine two or more components, or may have different component configurations. The embodiment of the present application does not specifically limit the number, type, position, etc. of the modules of the electronic device 100.

[0105] The following describes an example of the implementation structure of the screen 10 of the electronic device 100 in some embodiments.

[0106] FIG4 is a schematic diagram of the structure of the screen 10 of the electronic device 100 shown in FIG1 in some embodiments, FIG5 is a schematic diagram of the cross-sectional structure of the screen 10 shown in FIG4 taken along AA, and FIG6 is an enlarged schematic diagram of the structure at B of the screen 10 shown in FIG4 . The viewing angle of the screen 10 in FIG4 is the viewing angle from the non-display side of the screen 10 to the screen 10. For the convenience of explanation, the position of the screen 10 and its components close to the display side of the screen 10 is defined as "outside" and the position close to the non-display side of the screen 10 is defined as "inside" in the following text. It should be noted that FIG4 and the related figures below only schematically illustrate some components included in the screen 10, and the actual shape, actual size, actual position and actual structure of these components are not limited by FIG4 and the figures below.

[0107] In some embodiments, as shown in Figures 4 and 5, screen 10 includes a display screen 1 and a reinforcement plate 2. Display screen 1 can be a bendable, flexible display screen. For example, display screen 1 can be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (OLED) display screen, a micro organic light-emitting diode (micro OLED) display screen, a micro organic light-emitting diode (micro OLED) display screen, or a quantum dot light-emitting diode (QLED) display screen.

[0108] In some embodiments, as shown in Figures 5 and 6, the display screen 1 may include a first screen portion 11 and a second screen portion 12, wherein the second screen portion 12 surrounds the first screen portion 11 and is connected to the first screen portion 11. The first screen portion 11 and the second screen portion 12 may be integrally formed structural members. The first screen portion 11 includes a first outer surface 111 and a first inner surface 112 disposed opposite each other, while the second screen portion 12 includes a second outer surface 121 and a second inner surface 122 disposed opposite each other. The first outer surface 111 and the second outer surface 121 face the display side of the screen 10, while the first inner surface 112 and the second inner surface 122 face the non-display side of the screen. The first outer surface 111 and the second outer surface 121 are flush, resulting in a smooth display surface and a uniform appearance for the screen 10. The first inner surface 112 is recessed relative to the second inner surface 122, forming a groove 13. The thickness of the first screen portion 11 is less than that of the second screen portion 12, and the groove 13 is formed on the inner side of the first screen portion 11. The opening of the groove 13 faces the non-display side of the screen 10 .

[0109] The second screen portion 12 of the display screen 1 is used to display images. The second screen portion 12 of the display screen 1 has a conventional display structure, which corresponds to the fully laminated structure of the display screen 1. The first screen portion 11 of the display screen 1 can reduce some of the laminated layers and retain some of the laminated layers relative to the second screen portion 12 to achieve a smaller number of laminated layers and a smaller thickness. At least a portion of the first screen portion 11 allows external light to pass through. The area of ​​the first screen portion 11 that allows external light to pass through is the light-transmitting area of ​​the first screen portion 11. In the embodiments of the present application, "at least a portion of the area" includes both a portion and the entire area. When the screen 10 is not assembled in the electronic device 100, for the screen 10, external light refers to light outside the screen 10. Compared to the light-transmitting area of ​​the fully laminated structure of the screen in traditional under-screen camera structures, the first screen portion 11 of this embodiment has a smaller thickness and fewer laminated layers, so the light-transmitting area of ​​the first screen portion 11 has a higher transmittance.

[0110] Illustratively, the reinforcing plate 2 is located on the side of the first inner surface 112 facing away from the first outer surface 111. The reinforcing plate 2 is stacked with the first screen portion 11 and fixedly connected to the display screen 1. In this case, the reinforcing plate 2 is stacked and fixed to the inner side of the first screen portion 11. The reinforcing plate 2 is at least partially located within the groove 13. For example, in the embodiment shown in Figure 5, the reinforcing plate 2 may be entirely located within the groove 13; in other embodiments, the reinforcing plate 2 may also be partially located within the groove 13.

[0111] At least a portion of the reinforcing plate 2 allows the passage of external light. This area of ​​the reinforcing plate 2 that allows the passage of external light is referred to as the light-transmitting area of ​​the reinforcing plate 2. External light can pass through the first screen portion 11 and the reinforcing plate 2 and enter the non-display space on the screen 10. For example, the light-transmitting area of ​​the reinforcing plate 2 is positioned opposite the light-transmitting area of ​​the first screen portion 11. In the thickness direction Z of the screen 10, there is an overlapping area between the two. External light then passes through the light-transmitting areas of the first screen portion 11 and the reinforcing plate 2, respectively, and enters the non-display space on the screen 10.

[0112] In the embodiment of the present application, the light-transmitting area 10a of the screen 10 is arranged to correspond to the light-transmitting area of ​​the first screen portion 11 and the light-transmitting area of ​​the reinforcing plate 2 to obtain a higher light transmittance. Since the reinforcing plate 2 is stacked with the first screen portion 11, the reinforcing plate 2 can enhance the structural strength of the first screen portion 11, thereby improving the structural strength of the display screen 1 at the groove 13. When the screen 10 is subjected to external pressure, extrusion or impact, the risk of deformation or damage is small, and the screen 10 has higher reliability. In addition, since the reinforcing plate 2 is at least partially located in the groove 13, the gap between the reinforcing plate 2 and the first screen portion 11 is small. When the first screen portion 11 is squeezed or pressed, the deformation space in the thickness direction Z of the screen 10 is small, so that the reinforcing plate 2 has a better reinforcing effect on the first screen portion 11.

[0113] Among them, in the thickness direction Z of the screen 10, the light-transmitting area of ​​the first screen portion 11 completely covers the light-transmitting area 10a of the screen 10, and the light-transmitting area of ​​the reinforcement plate 2 completely covers the light-transmitting area 10a of the screen 10, so that the light-transmitting area 10a of the screen 10 as a whole has a higher light transmittance, and the optical path environment is consistent or similar, so that the lighting quality of the optical device 30 located below the light-transmitting area 10a of the screen 10 is better.

[0114] In some embodiments, the first screen portion 11 of the display screen 1 may have one or more layers, and most or all of the layers of the first screen portion 11 may be layers with a relatively high light transmittance. In this case, the high light transmittance of the first screen portion 11 results in a high light transmittance in the light-transmitting area 10a of the screen 10, which is beneficial for improving the lighting quality of the optical device 30. Exemplarily, the light transmittance of all or most of the layers of the first screen portion 11 may be greater than or equal to 20%, such as 45%, 68%, 80%, 85%, 91%, 93%, 98%, etc. The minimum value of the light transmittance of the layers of the first screen portion 11 varies according to the lighting requirements of the optical device 30.

[0115] In some embodiments, the display screen 1 may include a first stack (not shown) and a second stack (not shown). The first stack is located between the first screen portion 11 and the second screen portion 12, while the second stack is located in the second screen portion 12. The first stack has a higher light transmittance than the second stack. That is, the first screen portion 11 retains the first stack with a higher light transmittance relative to the second screen portion 12, while reducing the second stack with a lower light transmittance. For example, the light transmittance of the first stack is greater than 20%, while the light transmittance of the second stack is less than 20%.

[0116] In this embodiment, the first screen portion 11 reduces the number of layers with low transmittance and retains the number of layers with high transmittance, thereby improving the overall transmittance. The first layer is one of the layers retained by the first screen portion 11, and the second layer is one of the layers reduced by the first screen portion 11 relative to the second screen portion 12. The embodiment of the present application does not limit the number of layers reduced by the first screen portion 11 relative to the second screen portion 12 to be all layers with low transmittance, but may also include some layers with high transmittance. It is also not limited to the number of layers in the first screen portion 11 being all layers with high transmittance, and the first screen portion 11 is also allowed to include layers with low transmittance for achieving other functions (such as the light-shielding layer used for shading later).

[0117] The display screen 1 may be formed by mechanically removing a portion of the laminated layers in a local area to form the first screen portion 11. The display screen 1 may also be formed by reducing the number of laminated layers formed in a local area during the manufacturing process. This embodiment of the present application is not strictly limited to this.

[0118] In some embodiments, the light transmittance of the reinforcing plate 2 is higher than that of the second laminate. For example, the area of ​​the reinforcing plate 2 that allows ambient light to pass through has a higher light transmittance than the second laminate. In this embodiment, the light transmittance of the reinforcing plate 2 is higher than the light transmittance of the laminate reduced by the first screen portion 11. This results in the overall light transmittance of the stacked structure of the first screen portion 11 and the reinforcing plate 2 being higher than that of the second screen portion 12. The light-transmitting area 10a located in this stacked structure has a higher light transmittance, which helps improve the lighting quality of the optical device 30.

[0119] In some embodiments, as shown in FIG5 , the reinforcing plate 2 has a flat plate structure. The reinforcing plate 2 includes a first plate surface 211, a second plate surface 212, and a peripheral side surface 213. The first plate surface 211 and the second plate surface 212 are disposed opposite and parallel to each other, and the peripheral side surface 213 circumferentially connects the first plate surface 211 and the second plate surface 212. The first plate surface 211 of the reinforcing plate 2 faces the first screen portion 11, while the second plate surface 212 faces away from the first screen portion 11. In this embodiment, the reinforcing plate 2 has a simple structure, is easy to process, and has low cost.

[0120] Exemplarily, the reinforcing plate 2 is parallel to the first screen portion 11. Specifically, the first plate surface 211 and the second plate surface 212 of the reinforcing plate 2 are both parallel to the first outer surface 111 of the first screen portion 11. In this case, external light is less distorted as it passes through the first screen portion 11 and the reinforcing plate 2. This allows the optical device 30 to collect high-quality external light through the light-transmitting area 10a of the screen 10. For example, when the optical device 30 is a camera module, the camera module can capture high-quality images.

[0121] Exemplarily, the main structure of the reinforcement plate 2 is a plate body 21. The plate body 21 of the reinforcement plate 2 can be made of a material with high light transmittance and high structural strength. The light transmittance of the plate body 21 of the reinforcement plate 2 can be adjusted according to the lighting requirements of the optical device 30. Exemplarily, the light transmittance of the plate body 21 of the reinforcement plate 2 is greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc. In some examples, the light transmittance of the plate body 21 of the reinforcement plate 2 can be greater than or equal to 80%, which is beneficial for external light to pass through the light-transmitting area 10a of the screen 10, so as to increase the amount of light received by the camera module, so that the imaging quality of the camera module is higher, and the risk of stray light and ghosting is reduced.

[0122] Exemplarily, the plate body 21 of the reinforcing plate 2 can be made of a polymer material or optical glass. For example, the material of the plate body 21 of the reinforcing plate 2 can be a transparent plastic, such as polyethylene terephthalate (PET) material, polycarbonate (PC) material, transparent polyimide (CPI) material, cyclo olefin polymer (COP) material, triacetyl cellulose (TAC) material, etc., or the material of the plate body 21 of the reinforcing plate 2 can be ultra thin glass (UTG).

[0123] In some embodiments, as shown in FIG5 , the screen 10 further includes an adhesive 3, which is located between the reinforcement plate 2 and the first inner surface 112 and fixedly connects the reinforcement plate 2 and the first inner surface 112. At this time, the adhesive 3 is fixedly connected to the first board surface 211 of the reinforcement plate 2. The reinforcement plate 2 is fixed to the first inner surface 112 of the first screen portion 11 in a stacked manner. The reinforcement plate 2 can directly reinforce the first screen portion 11, and the reinforcement effect is good. In addition, the reinforcement plate 2 and the first screen portion 11 are compactly arranged, which is also conducive to controlling the thickness of the light-transmitting area 10a of the screen 10. When the position of the optical device 30 is the bottleneck of the overall thickness of the electronic device 100, the overall thickness of the electronic device 100 can be effectively controlled, which is conducive to achieving a thinner electronic device 100.

[0124] Adhesive 3 allows external light to pass through. Adhesive 3 can be made of a material with high light transmittance. For example, the light transmittance of adhesive 3 can be greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc. In some examples, the light transmittance of adhesive 3 is greater than or equal to 80%. Exemplarily, the adhesive can be an optically clear adhesive (OCA) or a pressure-sensitive adhesive.

[0125] For example, as shown in FIG5 , in the thickness direction Z of the screen 10, the sum of the thickness of the reinforcing plate 2 and the thickness of the adhesive 3 is equal to the depth of the groove 13 . At this point, the second plate surface 212 of the reinforcing plate 2 is flush with the second inner surface 122 of the second screen portion 12 . The provision of the reinforcing plate 2 does not increase the thickness of the screen 10 , thereby contributing to a thinner electronic device 100 . Furthermore, it also smoothes the inner surface of the screen 10 , simplifying assembly and simplifying the assembly structure of the screen 10 .

[0126] In some embodiments, as shown in Figures 5 and 6 , the surface of the second screen portion 12 facing the groove 13 is the sidewall 131 of the groove 13, and a gap 132 is formed between the peripheral side surface 213 of the reinforcing plate 2 and the sidewall 131 of the groove 13. In this embodiment, the gap 132 between the peripheral side surface 213 of the reinforcing plate 2 and the sidewall 131 of the groove 13 serves as an assembly gap. This assembly gap reduces the risk of damage to the display screen 1 from the reinforcing plate 2, thereby protecting the display screen 1.

[0127] Figure 7 is a schematic diagram of a portion of the structure of screen 10 shown in Figure 1 in alternative embodiments. The viewing angle of screen 10 in Figure 7 is when looking at screen 10 from the non-display side. Screen 10 in the embodiment of Figure 7 can include most of the technical features of screen 10 in the previous embodiment. The following mainly describes the differences between the two embodiments, and the common features are not repeated here.

[0128] In the embodiment of the present application, the shape of the reinforcing plate 2 can have a variety of implementation structures, and the shape of the reinforcing plate 2 can be adapted to the shape of the groove 13 as much as possible to achieve full support for the first screen portion 11. For example, as shown in Figure 6, the groove 13 is a circular groove, and the reinforcing plate 2 is a circular flat plate. Alternatively, as shown in Figure 7, the groove 13 is a circular groove, and the reinforcing plate 2 is a polygonal flat plate, such as an octagonal flat plate. In some other embodiments, the number of sides of the reinforcing plate 2 can also be six sides, four sides, twelve sides, etc. In some other embodiments, the reinforcing plate 2 can also be a flat plate structure of other shapes, and the embodiment of the present application does not strictly limit the shape of the reinforcing plate 2. In some other embodiments, the groove 13 can also have other shapes, such as polygons, etc., and the embodiment of the present application does not strictly limit the shape of the groove 13.

[0129] In some embodiments, in the planar direction of the screen 10, the opening area of ​​the groove 13 has a first area, the portion of the reinforcing plate 2 located within the groove 13 has a second area, and the ratio of the second area to the first area is greater than or equal to 80%. For example, the ratio of the second area to the first area can be 82%, 84%, 85.6%, 88%, 90%, 92%, 95%, etc. The planar direction of the screen 10 is perpendicular to the thickness direction Z of the screen 10.

[0130] In this embodiment, because the ratio of the area of ​​the portion of reinforcing plate 2 located within groove 13 to the opening area of ​​groove 13 is greater than or equal to 80%, the larger area of ​​reinforcing plate 2 located within groove 13 provides better support for first screen portion 11 and improves the reliability of screen 10. Furthermore, the larger area of ​​reinforcing plate 2 helps ensure that all external light entering the non-display side space of screen 10 through light-transmitting area 10a of screen 10 is able to pass through reinforcing plate 2, maintaining a consistent or similar optical path environment. This reduces the risk of distortion in images captured by optical device 30 and improves the lighting quality of optical device 30.

[0131] It is understandable that the ratio of the second area to the first area is as large as possible while ensuring sufficient assembly clearance between the peripheral side surface 213 of the reinforcement plate 2 and the groove wall of the groove 13 to provide a better supporting environment and optical path environment.

[0132] In some embodiments, the width of the gap 132 between the circumferential side surface 213 of the reinforcing plate 2 and the sidewall 131 of the groove 13 can be constant or variable along the circumference of the reinforcing plate 2. For example, as shown in FIG6 , the sidewall 131 of the groove 13 is a cylindrical surface, the circumferential side surface 213 of the reinforcing plate 2 is a cylindrical surface, the centerlines of the two coincide, and the width of the gap 132 is constant along the circumference of the reinforcing plate 2. Alternatively, the sidewall 131 of the groove 13 can be a cylindrical surface, the circumferential side surface 213 of the reinforcing plate 2 is also a cylindrical surface, the centerlines of the two are offset, and the width of the gap 132 varies along the circumference of the reinforcing plate 2. Alternatively, as shown in FIG7 , the sidewall 131 of the groove 13 can be a cylindrical surface, the circumferential side surface 213 of the reinforcing plate 2 is a polygonal cylindrical surface, the centerlines of the two coincide, and the width of the gap 132 varies along the circumference of the reinforcing plate 2. The embodiment of the present application does not strictly limit the specific value and design rules of the width of the gap 132 between the peripheral side surface 213 of the reinforcement plate 2 and the side wall 131 of the groove 13.

[0133] In some embodiments, as shown in Figures 5 and 6 , the reinforcing plate 2 further includes a light-blocking layer 22, which covers the peripheral side surface 213 of the plate body 21. The light-blocking layer 22 can be made of a light-absorbing or light-blocking material to block the light path. For example, the light-blocking layer 22 can be an ink layer, which can be formed by directly applying ink to the peripheral side surface 213 of the plate body 21. Alternatively, the light-blocking layer 22 can be a black film, which can be fixed to the peripheral side surface 213 of the plate body 21 by adhesive bonding or other means.

[0134] In this embodiment, the light-blocking layer 22 of the reinforcing plate 2 is disposed facing the sidewall 131 of the groove 13. The light-blocking layer 22 can absorb stray light or block the propagation of stray light, thereby reducing stray light entering the lighting path of the optical device 30, reducing the risk of crosstalk, and improving the lighting quality of the optical device 30. The stray light can be, but is not limited to, light emitted by the display screen 1 or light emitted by components such as a flash within the electronic device 100.

[0135] In some embodiments, as shown in Figures 5 and 6, the display screen 1 may include a light-shielding layer 14, which is annular. The light-shielding layer 14 is at least partially located in the first screen portion 11. In other words, the light-shielding layer 14 is at least a portion of the structure of the first screen portion 11. In the thickness direction Z of the screen 10, the light-shielding layer 14 covers the gap 132 and the periphery of the reinforcing plate 2, while exposing the central portion of the reinforcing plate 2. The light-shielding layer 14 can be made of a light-absorbing material or a light-blocking material. For example, the light-shielding layer 14 can be an ink layer. The periphery of the reinforcing plate 2 and the central portion of the reinforcing plate 2 are two regions of the reinforcing plate 2. The periphery of the reinforcing plate 2 is arranged around the central portion of the reinforcing plate 2, and the two regions have a relative positional relationship. However, the embodiments of the present application do not strictly limit the boundary position between the two regions. For example, in the radial direction of the reinforcing plate 2, the width of the periphery of the reinforcing plate 2 can be greater than, equal to, or less than the width of the central portion of the reinforcing plate 2. The radial direction of the reinforcing plate 2 is parallel to the plate surface of the reinforcing plate 2 and passes through the center line of the reinforcing plate 2 ; the center line of the reinforcing plate 2 is perpendicular to the plate surface of the reinforcing plate 2 .

[0136] In this embodiment, the light shielding layer 14 shields the gap 132 between the reinforcing plate 2 and the sidewall 131 of the groove 13, as well as the periphery of the reinforcing plate 2, thereby improving the appearance of the screen 10. The light shielding layer 14 also absorbs stray light, reducing the stray light that enters the lighting path of the optical device 30, thereby improving the lighting quality of the optical device 30. The stray light may be, but is not limited to, light emitted by the display screen 1 or light emitted by components such as a flash within the electronic device 100.

[0137] Exemplarily, the light-shielding layer 14 may be in the shape of a circular ring. The light-shielding layer 14 includes an inner ring surface and an outer ring surface that are relatively arranged, and both the inner ring surface and the outer ring surface are circular. In some other embodiments, the light-shielding layer 14 may also be other ring structures, such as an elliptical ring shape, a square ring shape, etc. In some other embodiments, the light-shielding layer 14 may also be an irregular ring shape. Exemplarily, the shape of the inner ring surface of the light-shielding ring may be different from the shape of the outer ring surface, for example, the shape of the inner ring surface is circular, and the shape of the outer ring surface is square. Alternatively, the shape of the inner ring surface of the light-shielding ring is the same as the shape of the outer ring surface, but the centers of the two are staggered. The embodiment of the present application does not strictly limit the specific shape of the light-shielding layer 14.

[0138] For example, the distance between the inner annular surface and the outer annular surface of the light shielding layer 14 may be between 0.05 mm and 0.3 mm, for example, 0.1 mm, 0.12 mm, 0.15 mm, 0.2 mm, etc.

[0139] FIG8 is a partial schematic diagram of the internal structure of screen 10 of electronic device 100 shown in FIG1 in another embodiment. Screen 10 in the embodiment of FIG8 may include most of the technical features of screen 10 in the previous embodiment. The following mainly describes the differences between the two embodiments, and the common parts are not repeated.

[0140] In some embodiments, as shown in FIG5 , the light-shielding layer 14 may be completely located in the first screen portion 11. In this case, the first screen portion 11 includes the light-shielding layer 14. In other embodiments, as shown in FIG8 , the light-shielding layer 14 may be partially located in the first screen portion 11 and partially located in the second screen portion 12. In other words, the light-shielding layer 14 may extend from the first screen portion 11 to the second screen portion 12. The shape of the portion of the light-shielding layer 14 located in the second screen portion 12 may be regular or irregular, and this is not strictly limited in the embodiments of the present application. The light-shielding layer 14 may be formed during the preparation process of the display screen 1.

[0141] In the embodiment of the present application, the shape and position of the light shielding layer 14 affect the display effect of the screen 10 .

[0142] Fig. 9 is a schematic diagram of a portion of the structure of the screen 10 shown in Fig. 4 at another angle. The viewing angle of the screen 10 shown in Fig. 9 is a viewing angle from the display side of the screen to the screen 10.

[0143] In some embodiments, as shown in Figures 5 and 9 , the screen 10 further includes a light-shielding area 10b and a display area 10c. The light-shielding area 10b surrounds the light-transmitting area 10a, and the display area 10c surrounds the light-shielding area 10b. For ease of illustration in Figure 9 , the display area 10c is indicated by angled fill lines, the light-shielding area 10b by grid fill lines, and the light-transmitting area 10a has no fill lines. The display area 10c of the screen 10 corresponds to the second screen portion 12 of the display screen 1 and is used to display images. The light-shielding area 10b, located between the display area 10c and the light-transmitting area 10a, can block external light. The light-shielding area 10b corresponds to the light-shielding layer 14 of the display screen 1. In some examples, the edge portion of the second screen portion 12 of the display screen 1 near the groove 13 may not be used for displaying images, but may be used to block external light. In this case, the light-shielding area 10b also corresponds to this portion of the structure. In some embodiments, the light-shielding area 10b can also be used to block light within the electronic device 100.

[0144] In this embodiment, since the light shielding layer 14 is annular, the light-transmitting area 10a is circular and the light shielding area 10b is annular. Since the light shielding layer 14 is completely located in the first screen portion 11, the light shielding area 10b is correspondingly located in the first screen portion 11.

[0145] Fig. 10 is a schematic diagram of a portion of the structure of the screen 10 shown in Fig. 8 at another angle. The viewing angle of the screen 10 shown in Fig. 10 is a viewing angle from the display side of the screen to the screen 10.

[0146] In other embodiments, as shown in Figures 8 and 10, the light-shielding layer 14 is partially located in the first screen portion 11 and partially located in the second screen portion 12. The position of the light-shielding area 10b changes with the light-shielding layer 14, and the light-shielding area 10b is partially located in the first screen portion 11 and partially located in the second screen portion 12. Exemplarily, the inner annular surface and the outer annular surface of the light-shielding layer 14 can both be circular, and the centers of the two circles are staggered. In this case, the light-shielding layer 14 is an irregular ring, the light-shielding area 10b corresponds to the irregular ring area, the light-transmitting area 10a is circular, and the non-display area surrounded by the display area 10c (that is, the area formed by the light-transmitting area 10a and the light-shielding area 10b) is circular.

[0147] In the embodiment of the present application, the first screen portion 11 of the display screen 1 may have various implementation structures, for example:

[0148] In some examples, the first screen portion 11 retains the outermost layer (cover layer) of the screen 10 compared to the second screen portion 12, that is, the layer of the screen 10 closest to the user side. The first screen portion 11 also includes a shading layer 14, which is stacked on the inner surface of the outermost layer. The first screen portion 11 reduces the remaining layers compared to the second screen portion 12.

[0149] FIG11 is a schematic structural diagram of the display screen 1 shown in FIG5 in some examples.

[0150] In some examples, as shown in FIG11 , the display screen 1 includes a display panel 151, a protective cover plate 152, a light shielding layer 14, and an adhesive layer 153. The display panel 151 is provided with a light hole 1511. The protective cover plate 152 is stacked on the light-emitting side of the display panel 151, covering the light hole 1511. The light shielding layer 14 is fixed to the surface of the protective cover plate 152 facing the light hole 1511. The adhesive layer 153 is located between the display panel 151 and the protective cover plate 152, and bonds the display panel 151 and the protective cover plate 152 together.

[0151] In this example, the portion of the protective cover 152 corresponding to the light aperture 1511 and the light-shielding layer 14 form the first screen portion 11, while the remaining portion of the protective cover 152, the adhesive layer 153, and the display panel 151 form the second screen portion 12. The protective cover 152 may include one or more laminated layers, and the display panel 151 may include multiple laminated layers. One of the laminated layers of the protective cover 152 corresponds to the first laminated layer described above, and one of the laminated layers of the display panel 151 corresponds to the second laminated layer described above. The adhesive layer 153 may be made of transparent optical adhesive.

[0152] FIG12 is a schematic structural diagram of the display screen 1 shown in FIG5 in other examples.

[0153] In some examples, as shown in FIG12 , the display screen 1 includes a display panel 151, a protective cover plate 152, a light shielding layer 14, and an adhesive layer 153. The protective cover plate 152 is stacked on the light-emitting side of the display panel 151. The adhesive layer 153 is located between the display panel 151 and the protective cover plate 152, and bonds the display panel 151 and the protective cover plate 152 together. The display panel 151 includes a first portion 151a with a smaller thickness and a second portion 151b with a larger thickness. A groove 13 is formed on the side of the first portion 151a facing away from the protective cover plate 152. The light shielding layer 14 is fixed to the surface of the first portion 151a facing away from the protective cover plate 152.

[0154] In this example, the portion of the protective cover 152 corresponding to the groove 13, the portion of the adhesive layer 153 corresponding to the groove 13, the first portion 151a of the display panel 151, and the light shielding layer 14 form the first screen portion 11, and the remaining portion of the protective cover 152, the remaining portion of the adhesive layer 153, and the second portion 151b of the display panel 151 form the second screen portion 12. The protective cover 152 may include one or more laminates, and the display panel 151 may include multiple laminates. One of the laminates of the protective cover 152 or the first portion 151a of the display panel 151 corresponds to the first laminate described above, and one of the laminates of the second portion 151b of the display panel 151 corresponds to the second laminate described above. The adhesive layer 153 may be made of transparent optical adhesive.

[0155] FIG13 is a schematic diagram of the internal structure of the second portion 151 b of the display panel 151 of the display screen 1 shown in FIG12 .

[0156] In some embodiments, as shown in FIG13 , the display panel 151 may be an organic light-emitting diode panel. The second portion 151 b of the display panel 151 may include a substrate 161 (basal plate, BP), a thin film transistor (TFT) 162, a pixel definition layer 163 (pixel define layer, PDL), a pixel unit layer 164, an encapsulation layer 165, a touch panel 166 (touch panel, TP), a protective layer 167 (overcoating, OC), a connecting layer 168 and a polarizer 169 (polarizer, POL). In this embodiment, the polarizer 169 is a layer of the display panel 151 close to the user. FIG4 only schematically shows two thin film transistors 162. The number of thin film transistors 162 in the second portion 151 b of the display panel 151 is not specifically limited.

[0157] For example, substrate 161 is used to provide a supporting base for the layers thereon (e.g., thin film transistor 162). The material of substrate 161 can be polyimide (PI), polyethylene terephthalate (PET), paper, metal, ultra-thin glass, etc.

[0158] As shown in FIG13 , the thin film transistor 162 includes a buffer layer 1621 (buffer), an active layer 1622, a gate insulator 1623 (GI), an interlayer dielectric 1611 (ILD), a gate 1624 (gate), a source 1612 (S), a drain 1613 (D), a planarization layer 1614 (PLN), a first trace 1615, and a second trace 1616. For example, the interlayer dielectric 1611 includes a first interlayer dielectric 1625 and a second interlayer dielectric 1626. The source 1612 includes a first source electrode 1627 and a second source electrode 1629. The planarization layer 1614 includes a first planarization layer 1628 and a second planarization layer 1620.

[0159] Exemplarily, a buffer layer 1621 is disposed on a substrate 161. An active layer 1622 is disposed on a surface of the buffer layer 1621 away from the substrate 161. A gate insulating layer 1623 is disposed on a surface of the buffer layer 1621 away from the substrate 161 and covers the active layer 1622. A gate 1624 and a first trace 1615 are both disposed on a surface of the gate insulating layer 1623 away from the buffer layer 1621, with the gate 1624 spaced apart from the first trace 1615. A first interlayer insulating layer 1625 is disposed on a surface of the gate insulating layer 1623 away from the buffer layer 1621 and covers the gate 1624 and the first trace 1615. A second trace 1616 is disposed on a surface of the first interlayer insulating layer 1625 away from the gate insulating layer 1623. A second interlayer insulating layer 1626 is disposed on a surface of the first interlayer insulating layer 1625 away from the gate insulating layer 1623 and covers the second trace 1616.

[0160] Illustratively, portions of the first source electrode 1627 and the first drain electrode 1613 are disposed on a surface of the second interlayer insulating layer 1626 away from the first interlayer insulating layer 1625, while the remaining portions pass through the second interlayer insulating layer 1626, the first interlayer insulating layer 1625, and the gate insulating layer 1623 to connect to the active layer 1622. A first planarizing layer 1628 is disposed on a surface of the second interlayer insulating layer 1626 away from the first interlayer insulating layer 1625 and covers portions of the first source electrode 1627 and the first drain electrode 1613. A portion of the second source electrode 1629 is disposed on a surface of the first planarizing layer 1628 away from the second interlayer insulating layer 1626, while the remaining portion passes through the first planarizing layer 1628 to connect to the first source electrode 1627. A second planarizing layer 1620 is disposed on the first planarizing layer 1628 and covers a portion of the second source electrode 1629.

[0161] The above is one embodiment of the thin-film transistor 162 provided in this application. In other embodiments, the thin-film transistor 162 may be provided with only the first source electrode 1627, the first drain electrode 1613, and the first planarization layer 1628. This embodiment of the application does not limit the specific layer structure of the thin-film transistor 162. In addition, the positions of the first source electrode 1627 and the first drain electrode 1613 may also be swapped.

[0162] As shown in Figure 13, the pixel definition layer 163 can be provided on the surface of the second planar layer 1620 of the thin-film transistor 162, away from the first planar layer 1628. The pixel unit layer 164 can be used to implement a display function and is also called a light-emitting device layer. The pixel unit layer 164 may include an anode 1641 (anode), an emission layer 1642 (EL layer), and a cathode 1643 (cathode) stacked in sequence. A portion of the anode 1641 can be provided on the surface of the second planar layer 1620 away from the first planar layer 1628, while another portion can pass through the second planar layer 1620 to connect to the second source electrode 1629. The emission layer 1642 can be provided on the surface of the anode 1641 away from the second planar layer 1620. The cathode 1643 can be provided on the surface of the emission layer 1642 away from the anode 1641.

[0163] It is understood that the cathode 1643 can be prepared using a full-surface evaporation method, so the cathode 1643 is a continuous layer structure in the second portion 151b. The material of the cathode 1643 can be a magnesium-silver alloy or other silver-containing alloys.

[0164] For example, the material of the light-emitting layer 1642 may be an organic material, including organic small molecule light-emitting materials, complex light-emitting materials, and high molecular polymers.

[0165] As shown in FIG13 , the encapsulation layer 165 includes a first encapsulation layer 1651, a second encapsulation layer 1652, and a flexible interlayer 1653. The first encapsulation layer 1651 is located on the surface of the cathode 1643 away from the light-emitting layer 1642. The flexible interlayer 1653 is located between the first encapsulation layer 1651 and the second encapsulation layer 1652.

[0166] It is understood that since the light-emitting layer 1642 is made of an organic material, it is easily oxidized when exposed to moisture and oxygen, causing the light-emitting layer 1642 to fail. In this case, the encapsulation layer 165 can encapsulate the pixel unit layer 164, that is, protect the pixel unit layer 164, thereby preventing moisture and oxygen in the air from affecting the life of the light-emitting layer 1642.

[0167] It is understood that the flexible interlayer 1653 can be used to buffer water and oxygen for the thin film transistor 162, pixel unit layer 164 and other structures below the encapsulation layer 165, thereby reducing encapsulation failure caused by foreign matter. The first encapsulation layer 1651 and the second encapsulation layer 165 can also seal the flexible interlayer 1653.

[0168] For example, the first encapsulation layer 1651 and the second encapsulation layer 1652 may be SiO2 layers or Si3N4 layers fabricated by chemical vapor deposition (CVD), and the flexible interlayer 1653 may be an acrylate or cured polyester polymer organic layer formed by ink jet printing (IJP) technology.

[0169] Illustratively, the touch panel 166 is located on the surface of the encapsulation layer 165 away from the substrate 161. The protective layer 167 is disposed on the surface of the touch panel 166 away from the pixel unit layer 164. The connecting layer 168 is disposed between the protective layer 167 and the polarizer 169. The connecting layer can be made of a pressure-sensitive adhesive (PSA).

[0170] In the second portion 151b of the display panel 151, one or more of the buffer layer 1621, the gate insulating layer 1623, the interlayer insulating layer 1611, the planar layer 1614, the encapsulation layer 165, the touch panel 166, the protective layer 167, the connecting layer 168, and the polarizer 169 can be made of a material with high light transmittance. The one or more layers with high light transmittance in the second portion 151b of the display panel 151 can be simultaneously laid out in the first portion 151a of the display panel 151 to form a part of the first screen portion 11 of the display screen 1. For example, the first portion 151a of the display panel 151 can include the encapsulation layer 165, the touch panel 166, the protective layer 167, the connecting layer 168, and the polarizer 169, but minus other layers. The embodiment of the present application does not strictly limit the specific layers of the first portion 151a of the display panel 151.

[0171] In other embodiments, the stacking structure of the second portion 151b of the display panel 151 may also have a different implementation structure. For example, the touch panel 166 may not be included, and the related stacking structures of the first portion 151a of the display panel 151 may be adaptively changed.

[0172] It can be understood that the above-mentioned exemplary structures of the display screen 1 are all described based on the example that the light-shielding layer 14 is completely located in the first screen portion 11. When the light-shielding layer 14 is partially located in the first screen portion 11 and partially located in the second screen portion 12, the relevant structures can be adaptively adjusted, which will not be elaborated here.

[0173] The following continues to describe the implementation structure of the screen 10 provided in the embodiment of the present application in other embodiments.

[0174] The primary difference between the screen 10 in the following embodiments and the screen 10 in the previous embodiments lies in the structural changes of the reinforcement plate 2 and / or the structural changes of the connection between the reinforcement plate 2 and the display screen 1. The following description will primarily focus on the modified aspects of the solution, while identical or similar aspects will not be reiterated. For example, unless otherwise noted, the structure of the display screen 1 in the following embodiments can refer to the relevant description of the previous embodiments. The unchanged structural portions of the reinforcement plate 2 and the unchanged connection between the reinforcement plate 2 and the display screen 1 in the following embodiments can also refer to the relevant description of the previous embodiments.

[0175] FIG14 is a partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 shown in FIG1 in another embodiment. The screen 10 of the embodiment of FIG14 may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two embodiments, and the common parts are not repeated.

[0176] In some embodiments, as shown in FIG14 , the reinforcement plate 2 may further include a light-blocking layer 23, which is fixed to the surface of the plate body 21 of the reinforcement plate 2 facing away from the first screen portion 11. The light-blocking layer 23 may be annular, with an inner diameter of the light-blocking layer 23 being smaller than an inner diameter of the light-shielding layer 14, an outer diameter of the light-blocking layer 23 being larger than an inner diameter of the light-shielding layer 14, and an inner space of the light-blocking layer 23 facing an inner space of the light-shielding layer 14. The light-blocking layer 23 may be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer 23 may be an ink layer, which may be formed by directly applying ink to the surface of the plate body 21. Alternatively, the light-blocking layer 23 may be a black film, which may be fixed to the surface of the plate body 21 by bonding or the like.

[0177] In the embodiment of Figure 14, the light-transmitting area 10a and the light-shielding area 10b of the screen 10 change with the positions of the light-blocking layer 23 and the light-shielding layer 14. The light-transmitting area 10a of the screen 10 corresponds to the area where the inner space of the ring of the light-blocking layer 23 is located, and the light-shielding area 10b corresponds to the area where the light-blocking layer 23 and the light-shielding layer 14 are located.

[0178] In this embodiment, since the surface of the plate body 21 of the reinforcement plate 2 facing away from the first screen portion 11 is close to the non-display side of the screen 10, it is also close to the optical device 30 (not shown in the figure) located on the non-display side of the screen 10. Therefore, the distance between the light blocking layer 23 located on the surface of the plate body 21 facing away from the first screen portion 11 and the optical device 30 is small. Based on the field of view characteristics of the optical device 30 for collecting light, the inner diameter of the light blocking layer 23 can be set to a smaller size, and then the outer diameter of the light blocking layer 23 can be smaller, the outer diameter of the reinforcement plate 2 can be smaller, and the opening size of the groove 13 of the display screen 1 can be smaller, which is beneficial to reducing the area of ​​the non-display area of ​​the screen 10 (that is, the total area including the light-transmitting area 10a and the light-shielding area 10b), and is beneficial to increasing the screen-to-body ratio of the screen 10.

[0179] The light shielding layer 14 can shield the gap 132 between the reinforcing plate 2 and the sidewall 131 of the groove 13 , thereby shielding the light-blocking structure step such as the ink step at the edge of the reinforcing plate 2 , thereby improving the appearance of the screen 10 .

[0180] FIG15 is a partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 shown in FIG1 in another embodiment. The screen 10 of the embodiment of FIG15 may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two embodiments, and the common parts are not repeated.

[0181] In some embodiments, as shown in FIG15 , the sum of the thickness of the reinforcing plate 2 and the thickness of the adhesive 3 in the thickness direction Z of the screen 10 is less than the depth of the groove 13 . In this case, the second plate surface 212 of the reinforcing plate 2 is recessed relative to the second inner surface 122 of the second screen portion 12 . The provision of the reinforcing plate 2 does not increase the thickness of the screen 10 , thereby contributing to a thinner electronic device 100 .

[0182] Figure 16 is a partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 shown in Figure 1 in alternative embodiments. Figure 17 is a schematic diagram of the structure of the reinforcing plate 2 of the screen 10 shown in Figure 16 . Figure 18 is a schematic diagram of the structure of the reinforcing plate 2 shown in Figure 17 from another angle. The screen 10 of the embodiment of Figure 16 can include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two embodiments, and the common features are not repeated here.

[0183] In some embodiments, as shown in Figures 16 to 18 , the reinforcement plate 2 includes a plate body 21, which includes a first plate body 21a and a second plate body 21b. The first plate body 21a is a portion of the plate body 21, and the second plate body 21b is another portion of the plate body 21. The first plate body 21a and the second plate body 21b can be stacked. The first plate body 21a and the second plate body 21b can be integrally formed structural members. In other embodiments, the first plate body 21a and the second plate body 21b can also be connected to each other via a translucent adhesive layer.

[0184] Exemplarily, the first plate body 21a includes a central portion and a peripheral edge. The peripheral edge of the first plate body 21a and the central portion of the first plate body 21a constitute two parts of the first plate body 21a. The peripheral edge of the first plate body 21a surrounds the central portion of the first plate body 21a, and the two parts are in a relative positional relationship. However, the embodiment of the present application does not strictly limit the position of the boundary between the two parts. For example, in the radial direction of the first plate body 21a, the width of the peripheral edge of the first plate body 21a can be greater than, equal to, or less than the width of the central portion of the first plate body 21a.

[0185] The second plate 21b is fixed to the middle of the first plate 21a. The outer diameter of the first plate 21a is larger than the outer diameter of the second plate 21b. The first plate 21a can be in the shape of a circular flat plate, and the second plate 21b can also be in the shape of a circular flat plate. In some other embodiments, the first plate 21a and the second plate 21b can also have other shapes, which are not strictly limited in the embodiments of the present application. For example, the transmittance of the first plate 21a and the second plate 21b is greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc.

[0186] The reinforcing plate 2 is partially located within the groove 13 and partially located outside the groove 13. For example, the second plate 21b is at least partially located within the groove 13 of the display screen 1, while the first plate 21a is located outside the groove 13. The periphery of the first plate 21a is fixedly connected to the second screen portion 12 of the display screen 1. For example, the periphery of the first plate 21a can be bonded to the second screen portion 12 via the adhesive layer 4.

[0187] Exemplarily, the first plate body 21a may include a first plate surface 211a, and the first plate surface 211a includes a middle portion and a periphery. The periphery of the first plate surface 211a and the middle portion of the first plate surface 211a are two regions of the first plate surface 211a. The periphery of the first plate surface 211a is arranged around the middle portion of the first plate surface 211a, and the two have a relative positional relationship. However, the embodiment of the present application does not strictly limit the boundary position between the two. The second plate body 21b is fixed to the middle portion of the first plate surface 211a. The periphery of the first plate surface 211a is fixedly connected to the second screen portion 12 of the display screen 1.

[0188] In this embodiment, the light-transmitting area 10a of the screen 10 can be arranged corresponding to the first screen portion 11, the middle portion of the first plate 21a, and the middle portion of the second plate 21b. The light-transmitting area 10a has a high light transmittance, so that the optical device 30 (not shown in the figure) located on the non-display side of the screen 10 can be illuminated. Since the first plate 21a and the second plate 21b are stacked with the first screen portion 11, and the second plate 21b is at least partially located in the groove 13, the reinforcement plate 2 can increase the structural strength of the first screen portion 11 and its surroundings, thereby improving the structural reliability of the screen 10. In addition, since the reinforcement plate 2 is fixedly connected to the second screen portion 12 and the thickness of the second screen portion 12 is relatively large, the second screen portion 12 can provide a more reliable fixing structure and supporting force, making the assembly structure of the reinforcement plate 2 and the display screen 1 more stable and reliable.

[0189] In some examples, the light transmittance of the plate 21 of the reinforcement plate 2 can be greater than or equal to 80%, thereby facilitating the passage of external light through the light-transmitting area 10a of the screen 10. Thus, when the optical device 30 employs a camera module, the light transmittance of the plate 21 can be configured to increase the amount of light received by the camera module, thereby enhancing the imaging quality of the camera module and reducing the risk of stray light and ghosting. The materials for the first plate 21a and the second plate 21b can be polymer materials or optical glass. For details, please refer to the previous embodiments and will not be repeated here.

[0190] In some embodiments, as shown in FIG16 , a gap 132 is formed between the peripheral side surface 213b of the second plate body 21b of the reinforcing plate 2 and the sidewall 131 of the groove 13. In this embodiment, the gap 132 between the peripheral side surface 213b of the second plate body 21b and the sidewall 131 of the groove 13 serves as an assembly gap. This assembly gap reduces the risk of damage to the display screen 1 from the reinforcing plate 2, thereby protecting the display screen 1.

[0191] In some embodiments, as shown in Figures 16 and 17, the reinforcement plate 2 also includes a light-blocking layer 23, which is annular. The light-blocking layer 23 is fixed to the periphery of the surface of the first plate body 21a facing away from the second plate body 21b. Exemplarily, the first plate body 21a also includes a second plate surface 212a, which is arranged to face away from the first plate surface 211a. The light-blocking layer 23 is fixed to the periphery of the second plate surface 212a, exposing the middle part of the second plate surface 212a. Among them, the periphery of the second plate surface 212a and the middle part of the second plate surface 212a are two parts of the second plate surface 212a, and the periphery of the second plate surface 212a is arranged around the middle part of the second plate surface 212a. There is a relative positional relationship between the two, but the embodiment of the present application does not strictly limit the boundary position between the two. For example, in the radial direction of the second plate surface 212a, the width of the periphery of the second plate surface 212a may be greater than, equal to, or less than the width of the middle portion of the second plate surface 212a.

[0192] Illustratively, in the thickness direction Z of the screen 10, the light-blocking layer 23 covers the gap 132 and the periphery of the second plate 21b. The light-blocking layer 23 can be made of a light-absorbing or light-blocking material to block the light path. For example, the light-blocking layer 23 can be an ink layer, which can be formed by directly applying ink to the second plate surface 212a. Alternatively, the light-blocking layer 23 can be a black film, which can be fixed to the second plate surface 212a by bonding or other means.

[0193] In this embodiment, the light-blocking layer 23 shields the gap 132 between the reinforcing plate 2 and the sidewall 131 of the groove 13, as well as the periphery of the second plate 21b, thereby improving the appearance of the screen 10. Furthermore, the light-blocking layer 23 can also absorb stray light, reducing the stray light that enters the lighting path of the optical device 30, thereby improving the lighting quality of the optical device 30. The stray light may be, but is not limited to, light emitted by the display screen 1, or light emitted by components such as a flash within the electronic device 100.

[0194] In addition, since the second plate surface 212a of the first plate body 21a is close to the non-display side of the screen 10, it is also close to the optical device 30 located on the non-display side of the screen 10. Therefore, the distance between the light blocking layer 23 located on the second plate surface 212a and the optical device 30 is small. Based on the field of view characteristics of the optical device 30 for collecting light, the inner diameter of the light blocking layer 23 can be set to a smaller size, and then the outer diameter of the light blocking layer 23 can be smaller, the outer diameter of the reinforcement plate 2 can be smaller, and the opening size of the groove 13 of the display screen 1 can be smaller, which is beneficial to increase the screen-to-body ratio of the screen 10.

[0195] Compared to the embodiment shown in FIG5 , which includes a light-shielding layer 14 on display screen 1, this embodiment does not require a light-shielding layer. This simplifies the manufacturing process and reduces the cost of display screen 1. Aside from the absence of light-shielding layer 14, the remaining structures of display screen 1 can be found in the description of the previous embodiments and will not be elaborated upon here. Furthermore, the display area (not shown) of display screen 1 is arranged based on the second screen portion 12, while the light-shielding area (not shown) is the region between the display area and the light-transmitting area 10a.

[0196] In some embodiments, as shown in Figures 16 to 18, the reinforcement plate 2 further includes a light-blocking layer 22, which covers at least the area of ​​the peripheral side surface 213b of the second plate body 21b located within the groove 13. For example, the light-blocking layer 22 can cover the peripheral side surface 213b of the second plate body 21b. The light-blocking layer 22 can be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer 22 can be an ink layer, which can be formed by directly applying ink to the peripheral side surface 213b of the second plate body 21b. Alternatively, the light-blocking layer 22 can be a black film, which can be fixed to the peripheral side surface 213b of the second plate body 21b by bonding or other means.

[0197] In this embodiment, the light-blocking layer 22 of the reinforcing plate 2 is disposed facing the sidewall 131 of the groove 13. The light-blocking layer 22 can absorb stray light or block the propagation of stray light, thereby reducing stray light entering the lighting path of the optical device 30, reducing the risk of crosstalk, and improving the lighting quality of the optical device 30. The stray light can be, but is not limited to, light emitted by the display screen 1 or light emitted by components such as a flash within the electronic device 100.

[0198] Figure 19 is a partial schematic diagram of the internal structure of screen 10 of electronic device 100 shown in Figure 1 in alternative embodiments, and Figure 20 is a schematic diagram of the structure of reinforcement plate 2 shown in Figure 19 from another angle. Screen 10 in the embodiment of Figure 19 can include most of the technical features of screen 10 in the previous embodiment. The following mainly describes the differences between the two, and the common features are not repeated here.

[0199] In some embodiments, as shown in Figures 19 and 20, the reinforcing plate 2 may include a light-transmitting portion 24 and a light-shielding portion 25, wherein the light-transmitting portion 24 has a higher light transmittance than the light-shielding portion 25. The light-transmitting portion 24 is used to allow external light to pass through, while the light-shielding portion 25 is used to block external light. The light-shielding portion 25 is arranged around the light-transmitting portion 24 and is fixed to the peripheral side surface 241 of the light-transmitting portion 24. Exemplarily, the light-transmitting portion 24 may be in the shape of an inverted truncated cone. For example, the light-transmitting portion 24 includes a first surface 242 and a second surface 243 disposed opposite to each other, and the peripheral side surface 241 of the light-transmitting portion 24 connects the first surface 242 and the second surface 243. The first surface 242 faces the first screen portion 11, and the second surface 243 faces away from the first screen portion 11. The area of ​​the first surface 242 is larger than that of the second surface 243. In some other embodiments, the light-transmitting portion 24 may also be cylindrical, which is not strictly limited in the embodiments of the present application.

[0200] The light transmittance of the light shielding portion 25 may be less than 20%, and the light transmittance of the light transmissive portion 24 may be greater than or equal to 20%. The light shielding portion 25 and the light transmissive portion 24 may be integrally formed components, for example, by two-color injection molding or other processes.

[0201] The reinforcing plate 2 is partially located within the groove 13 of the display screen 1 and partially located outside the groove 13. The light shielding portion 25 of the reinforcing plate 2 has a peripheral side surface 251 facing the side wall 131 of the groove 13. A gap 132 is formed between the peripheral side surface 251 of the light shielding portion 25 and the side wall 131 of the groove 13. In the thickness direction Z of the screen 10, the light shielding portion 25 covers the gap 132. The portion of the light shielding portion 25 located outside the groove 13 is fixedly connected to the second screen portion 12 of the display screen 1. For example, the flange portion of the light shielding portion 25 can be bonded to the second screen portion 12 via the adhesive layer 4.

[0202] In this embodiment, the light-transmitting area 10a of the screen 10 is arranged corresponding to the first screen portion 11 and the light-transmitting portion 24 of the reinforcement plate 2, and has a high light transmittance. The optical device 30 (not shown in the figure) located on the non-display side of the screen 10 can collect external light through the light-transmitting area 10a. The reinforcement plate 2 can increase the structural strength of the first screen portion 11 and its surroundings, making the screen 10 more reliable. In addition, the relative position of the light-shielding portion 25 and the light-transmitting portion 24 of the reinforcement plate 2 can be set according to the field of view characteristics of the optical device 30 for collecting light, so that it has a smaller volume while meeting the lighting needs of the optical device 30, which is conducive to reducing the opening size of the groove 13 of the display screen 1, and is conducive to increasing the screen-to-body ratio of the screen 10.

[0203] In some embodiments, the light shielding portion 25 can absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device 30 and improving the lighting quality of the optical device 30 .

[0204] In other embodiments of the present application, when the depth of the groove 13 of the display screen 1 is relatively small, the reinforcing plate 2 may not be located within the groove 13, but may be located entirely outside the groove 13, with the periphery of the reinforcing plate 2 fixedly connected to the second screen portion 12, and the middle portion of the reinforcing plate 2 covering the groove 13. In this case, when the first screen portion 11 is subjected to external pressure or impact, the reinforcing plate 2 can also provide support for the first screen portion 11, reducing the risk of damage to the first screen portion 11 and the risk of damage to the optical device 30 through the first screen portion 11.

[0205] The following is an example of how to implement the assembly structure of the screen 10, the housing 20, and the optical device 30 of the electronic device 100:

[0206] Fig. 21 is a schematic diagram of a cross-sectional structure of the electronic device 100 shown in Fig. 1 taken along CC in some embodiments. The screen 10 in Fig. 21 is illustrated by taking the screen 10 of the embodiment of Fig. 5 as an example.

[0207] In some embodiments, as shown in Figures 5 and 21 , the optical device 30 of the electronic device 100 is mounted on the housing 20 and located on the non-display side of the screen 10. For example, the optical device 30 may be located on the side of the reinforcing plate 2 of the screen 10 facing away from the first screen portion 11. The optical device 30 is used to collect external light that passes through the first screen portion 11 and the reinforcing plate 2. For example, the optical device 30 may be a camera module that collects external light that passes through the light-transmitting area 10a of the screen 10 to enable capture.

[0208] In this embodiment, the light-transmitting area 10a of the screen 10 has a high light transmittance, resulting in high imaging quality for the camera module. The reinforcing plate 2 of the screen 10 increases the structural strength of the first screen portion 11, minimizing the risk of deformation or damage to the first screen portion 11 when subjected to external pressure or impact. This also reduces the risk of damage to the optical device 30, thereby improving the reliability of the electronic device 100.

[0209] In some embodiments, as shown in FIG21 , the electronic device 100 may further include a support member 40, the support member 40 being in contact between the reinforcing plate 2 and the housing 20. The external light enters the optical device 30 through the incident surface 301 of the optical device 30.

[0210] In this embodiment, since the support member 40 abuts between the reinforcement plate 2 and the shell 20, the shell 20 can indirectly support the reinforcement plate 2 through the support member 40, and then support the first screen portion 11, so that the risk of deformation or damage of the first screen portion 11 when subjected to external pressure or impact is further reduced, and the screen 10 and the electronic device 100 obtain higher reliability.

[0211] The support member 40 can be made of an elastic material to provide support and cushioning functions. For example, the support member 40 can be made of foam, glue, tape, or other materials. During the assembly process of the electronic device 100, the support member 40 can also absorb assembly tolerances between the screen 10 and the housing 20, thereby improving the yield of the electronic device 100. The thickness of the support member 40 can be in the range of 0.1 mm to 0.2 mm.

[0212] The support member 40 can be arranged around the incident surface 301 of the optical device 30. The support member 40 can be roughly annular. In this embodiment, since the support member 40 is arranged around the incident surface 301 of the optical device 30, the arrangement of the support member 40 will not affect the lighting of the optical device 30. In addition, the support area of ​​the support member 40 for the reinforcement plate 2 is annular, and the support area is relatively evenly arranged around the periphery of the reinforcement plate 2, making it less likely for the reinforcement plate 2 to tilt, warp, or other problems. This ensures that the consistency of the light path of the light-transmitting area 10a of the screen 10 can be ensured while reinforcing the first screen portion 11.

[0213] For example, the support member 40 seals the reinforcing plate 2 and the housing 20. The support member 40 can seal the gap between the housing 20 and the reinforcing plate 2, thereby sealing the gap between the optical device 30 and the reinforcing plate 2, thereby reducing the risk of dust falling onto the incident surface 301 of the optical device 30 and achieving dust protection.

[0214] For example, the support member 40 may also abut between the second screen portion 12 and the housing 20. In this case, the housing 20 may indirectly support the second screen portion 12 through the support member 40, thereby further reducing the risk of deformation or damage to the screen 10 when subjected to external pressure or impact, thereby increasing the reliability of the screen 10 and the electronic device 100.

[0215] For example, the support member 40 may include two parts, one of which abuts between the reinforcing plate 2 and the housing 20, and the other abuts between the second screen portion 12 and the housing 20. These two parts may be connected to each other or independent of each other. In other embodiments, the support member 40 may not include the part abutting between the reinforcing plate 2 and the housing 20. In this case, the part abutting between the second screen portion 12 and the housing 20 may be disposed around the incident surface 301 of the optical device 30 and sealably connect the second screen portion 12 and the housing 20 to protect the optical device 30 from dust.

[0216] In the aforementioned embodiment, the support member 40 is a continuous structural member. In other embodiments, the support member 40 may also include multiple independent parts, which are arranged at intervals around the incident surface 301 of the optical device 30. The specific structure and specific arrangement position of the support member 40 are not strictly limited in the embodiments of the present application.

[0217] When the second plate surface 212 of the reinforcing plate 2 is flush with the second inner surface 122 of the second screen portion 12 , the assembly structure of the screen 10 , the support member 40 and the housing 20 is easier to achieve, with high assembly precision and low difficulty.

[0218] In other embodiments, the support member 40 may be made of a light-absorbing or light-blocking material. In the thickness direction Z of the screen 10, the support member 40 covers the gap 132 between the reinforcing plate 2 and the sidewall 131 of the groove 13, as well as the periphery of the reinforcing plate 2. In this case, the display screen 1 may not be provided with the light-shielding layer 14.

[0219] Figure 22 is a schematic diagram of the cross-sectional structure of the electronic device 100 shown in Figure 1 taken along line CC in some other embodiments. The electronic device 100 of the embodiment of Figure 22 can include most of the technical features of the electronic device 100 of the previous embodiment. The following mainly describes the differences between the two, and the common parts are not repeated. The screen 10 in Figure 22 is illustrated using the screen 10 of the embodiment of Figure 15 as an example.

[0220] In some embodiments, the second surface 212 of the reinforcing plate 2 is recessed relative to the second inner surface 122 of the second screen portion 12, thereby reducing the distance between the optical device 30 and the first screen portion 11. When the optical device 30 is a bottleneck in the overall thickness of the electronic device 100, the reduced distance between the optical device 30 and the first screen portion 11 effectively controls the overall thickness of the electronic device 100, facilitating a thinner electronic device 100.

[0221] Exemplarily, the support member 40 includes a first portion 401 and a second portion 402. The first portion 401 abuts between the reinforcement plate 2 and the housing 20, and the second portion 402 abuts between the second screen portion 12 and the housing 20. The first portion 401 surrounds the incident surface 301 of the optical device 30 and seals the reinforcement plate 2 and the housing 20; and / or, the second portion 402 surrounds the incident surface 301 of the optical device 30 and seals the second screen portion 12 and the housing 20. The first portion 401 may be at least partially located within the groove 13 of the display screen 1, and the second portion 402 may be located outside the groove 13. Other designs of the support member 40 can refer to the previous embodiments and are not described here.

[0222] Figure 23 is a schematic diagram of the cross-sectional structure of the electronic device 100 shown in Figure 1 taken along line CC in alternative embodiments. The electronic device 100 of the embodiment of Figure 23 may include most of the technical features of the electronic device 100 of the previous embodiment. The following text will primarily describe the differences between the two, and will not repeat the common features. The screen 10 in Figure 23 is illustrated using the screen 10 of the embodiment of Figure 16 as an example.

[0223] In some embodiments, the support member 40 is disposed between the reinforcing plate 2 and the housing 20. The support member 40 may be disposed around the incident surface 301 of the optical device 30. The support member 40 may seal the reinforcing plate 2 and the housing 20.

[0224] In this embodiment, since the reinforcing plate 2 is directly connected to the second screen portion 12 of the display screen 1 and the support member 40 is supported on the periphery of the reinforcing plate 2, when the first screen portion 11 or the second screen portion 12 of the display screen 1 is subjected to force or impact, the reinforcing plate 2, the support member 40 and the shell 20 can all provide stable and reliable support, thereby improving the reliability of the screen 10.

[0225] In the thickness direction Z of the screen 10 , the second screen portion 12 , the reinforcing plate 2 and the support member 40 may have an overlapping area, so that the support structure of the housing 20 for the screen 10 is more reliable.

[0226] In other embodiments, the housing 20 has a higher precision, and there may be no gap, or a very small gap, between the housing 20 and the reinforcing plate 2. There may also be no gap, or a very small gap, between the housing 20 and the portion of the second screen portion 12 near the groove 13. In this case, the electronic device 100 may not include the aforementioned support member 40, and the housing 20 may simply support the reinforcing plate 2 and the second screen portion 12.

[0227] Figure 24 is a schematic diagram of the cross-sectional structure of the electronic device 100 shown in Figure 1 taken along line CC in another embodiment, and Figure 25 is a schematic diagram of the structure of the screen 10 shown in Figure 24 from another angle. The electronic device 100 of the embodiment of Figure 24 can include most of the technical features of the electronic device 100 of the previous embodiment. The following mainly describes the differences between the two, and the common parts are not repeated.

[0228] In some embodiments, as shown in Figures 24 and 25 , the second screen portion 12 of the display screen 1 can semi-enclose the first screen portion 11. In this case, the first screen portion 11 and the groove 13 of the display screen 1 are located at the edge of the display screen 1, with one side of the groove 13 open. In this case, the shape of the reinforcement plate 2 can be adaptively modified based on the shape of the groove 13. A light-blocking layer 23 can be provided on the surface of the reinforcement plate 2 facing the optical device 30. For other structural designs of the reinforcement plate 2, refer to the embodiments shown in Figures 14, 15, or 16.

[0229] In this embodiment, since the light-blocking layer 23 is arranged on the surface of the reinforcement plate 2 facing the optical device 30, the distance between the light-blocking layer 23 and the optical device 30 is small, the inner diameter of the light-blocking layer 23 can be set to a smaller size, and then the outer diameter of the light-blocking layer 23 can be smaller, the outer diameter of the reinforcement plate 2 can be smaller, and the opening size of the groove 13 of the display screen 1 can be smaller, which is beneficial to increase the screen-to-body ratio of the screen 10, and is also beneficial to reduce the width of the overall frame of the electronic device 100, thereby improving the aesthetics of the entire machine.

[0230] The support member 40 can be positioned between the reinforcement plate 2 and the housing 20. The support member 40 can be positioned around the incident surface 301 of the optical device 30.
