Description

Technical Field

[0001] This application relates to the field of display device technology, and more particularly to a screen and electronic device. Background Technology

[0002] Electronic devices (such as laptops and mobile phones) may include a screen and a front-facing camera. The screen is used to display images, and the front-facing camera is used to capture images of the scene in front of the screen. In order to achieve a larger screen-to-body ratio, more and more electronic devices are placing the front-facing camera under the screen, forming an under-display camera structure.

[0003] Currently, under-display camera structures generally employ two approaches: The first approach involves a complete screen structure with a portion forming a light-transmitting area, beneath which the front-facing camera is placed. In this approach, because the light-transmitting area retains all screen layers and is relatively thick, its light transmittance is low, resulting in dark images and poor image quality from the front-facing camera. The second approach involves creating a light-transmitting hole in the screen, with the front-facing camera placed below it. While this approach allows the front-facing camera to capture light from the front of the screen through the hole, achieving better image quality, the hole reduces the screen's structural strength. This is especially true for flexible screens, where the structural strength at and around the light-transmitting hole is significantly reduced, making the screen more susceptible to damage from external pressure or impact, resulting in poor screen reliability.

[0004] Therefore, how to obtain areas with high light transmittance and high reliability in a screen has become an urgent problem to be solved. Summary of the Invention

[0005] This application provides a screen and an electronic device. The screen has an area with high light transmittance and high reliability.

[0006] In a first aspect, embodiments of this application provide a screen that can be applied in an electronic device, the electronic device including optical components located on the non-display side of the screen. The screen includes a display screen and a reinforcing plate. The display screen includes a first screen portion and a second screen portion, the second screen portion surrounding or partially surrounding the first screen portion. The second screen portion is connected to the first screen portion. The first screen portion and the second screen portion can be integrally formed structural components.

[0007] The first screen portion includes a first outer surface and a first inner surface arranged opposite to each other, and the second screen portion includes a second outer surface and a second inner surface arranged opposite to each other. The first outer surface and the second outer surface are flush, 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 the thickness of the second screen portion.

[0008] The second screen of the display is used to display images. The second screen can have a conventional display structure, corresponding to a full-layered display structure. Compared to the second screen, the first screen can have fewer layers and a smaller thickness by reducing some layers and retaining others.

[0009] 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 a groove and is fixedly connected to the display screen. At least a portion of the first screen portion and at least a portion of the reinforcing plate allow external light to pass through. External light can pass through the first screen portion and the reinforcing plate and enter the non-display side space of the screen.

[0010] The area of ​​the first screen that allows external light to pass through is called the light-transmitting area of ​​the first screen. The area of ​​the reinforcing plate that allows external light to pass through is called the light-transmitting area of ​​the reinforcing plate. In some implementations, the light-transmitting area of ​​the reinforcing plate and the light-transmitting area of ​​the first screen are positioned opposite each other, and there is an overlapping area between them in the thickness direction of the screen. External light passes through the light-transmitting areas of the first screen and the light-transmitting areas of the reinforcing plate in sequence and enters the non-display side space of the screen.

[0011] In this embodiment, the light-transmitting area of ​​the screen is configured to correspond to the light-transmitting area of ​​the first screen portion and the light-transmitting area of ​​the reinforcing plate, thereby achieving high light transmittance. Since the reinforcing plate is stacked with the first screen portion, it enhances the structural strength of the first screen portion, thus improving the structural strength of the display screen at the recess. This reduces the risk of deformation or damage to the screen when subjected to external pressure, compression, or impact, resulting in higher screen reliability. Furthermore, because the reinforcing plate is at least partially located within the recess, the gap between the reinforcing plate and the first screen portion is small. This reduces the deformation space in the thickness direction of the screen when the first screen portion is compressed or pressed, further enhancing the reinforcing effect of the reinforcing plate on the first screen portion.

[0012] In the thickness direction of the screen, the light-transmitting area of ​​the first screen completely covers the light-transmitting area of ​​the screen, and the light-transmitting area of ​​the reinforcing plate completely covers the light-transmitting area of ​​the screen, so that the overall light-transmitting area of ​​the screen has a high light transmittance and the light path environment is consistent or similar, so that the light-receiving quality of the optical devices located below the light-transmitting area of ​​the screen is better.

[0013] In some embodiments, the first screen portion of the display screen may have one or more layers, and most or all of the layers in the first screen portion may be layers with high light transmittance. In this case, the high light transmittance of the first screen portion results in high light transmittance in the light-transmitting area of ​​the screen, thereby improving the light-gathering quality of the optical components of the electronic device. For example, the light transmittance of all or most of the layers in the first screen portion may be greater than or equal to 20%, such as 45%, 68%, 80%, 85%, 91%, 93%, 98%, etc.

[0014] 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 light transmittance of the first stack is higher than that of the second stack. That is, the first screen portion retains the first stack with higher light transmittance relative to the second screen portion, while reducing the second stack with lower light transmittance. For example, the light transmittance of the first stack is higher than 20%, and the light transmittance of the second stack is lower than 20%.

[0015] In this embodiment, the first screen portion improves overall transmittance by reducing low-transmittance layers and retaining high-transmittance layers. The first layer is one of the layers retained in the first screen portion, and the second layer is one of the layers reduced in the first screen portion relative to the second screen portion. This embodiment does not limit the layers reduced in the first screen portion relative to the second screen portion to be all low-transmittance layers; it may include some high-transmittance layers. Nor does it limit the layers in the first screen portion to be all high-transmittance layers; it also allows the first screen portion to include low-transmittance layers used to achieve other functions.

[0016] In some possible implementations, the light transmittance of the reinforcing plate is higher than that of the second stack. For example, the light transmittance of the area of ​​the reinforcing plate that allows external light to pass through is higher than that of the second stack. In this embodiment, the light transmittance of the reinforcing plate is higher than the light transmittance of the stack reduced by the first screen portion, so that the overall light transmittance of the stack structure of the first screen portion and the reinforcing plate is higher than that of the second screen portion. The light-transmitting area located in this stack structure has high light transmittance, which is beneficial to improving the light-gathering quality of the optical device.

[0017] In some embodiments, the reinforcing plate has a flat plate structure. The reinforcing plate includes a first plate surface, a second plate surface, and a peripheral side surface. The first plate surface and the second plate surface are arranged opposite to each other and parallel to each other, and the peripheral side surface surrounds and connects the first plate surface and the second plate surface. Specifically, the first plate surface of the reinforcing plate faces the first screen portion, and 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 has a low cost.

[0018] For example, the reinforcing plate is parallel to the first screen portion. Specifically, both the first and second surfaces of the reinforcing plate are parallel to the first outer surface of the first screen portion. In this case, the distortion of external light as it passes through the first screen portion and the reinforcing plate is small, allowing the optical device to collect high-quality external light through the light-transmitting area of ​​the screen. For example, when the optical device is a camera module, the camera module captures better images.

[0019] For example, the main structure of the reinforcing plate is a plate body. The plate body of the reinforcing plate can be made of a material with high light transmittance and high structural strength. The light transmittance of the reinforcing plate body can be adjusted according to the light-gathering requirements of the optical devices. For example, the light transmittance of the reinforcing plate body 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 reinforcing plate body can be greater than or equal to 80%, which facilitates the passage of external light through the light-transmitting area of ​​the screen, thereby increasing the amount of light received by the camera module, resulting in higher image quality and reducing the risk of stray light and ghosting.

[0020] For example, the body of the reinforcing plate can be made of polymer materials or optical glass. For instance, the material of the reinforcing plate can be transparent plastic, such as polyethylene terephthalate, polycarbonate, transparent polyimide, cyclic olefin polymer, cellulose triacetate, etc., or the material of the reinforcing plate can be ultra-thin glass.

[0021] In some possible implementations, the opening area of ​​the groove in the plane of the screen is a first area, and the portion of the reinforcing plate located in the groove has a second area, the ratio of the second area to the first area being greater than or equal to 80%.

[0022] In this embodiment, since the ratio of the area of ​​the portion of the reinforcing plate located within the groove to the opening area of ​​the groove is greater than or equal to 80%, the area of ​​the portion of the reinforcing plate located within the groove is relatively large. This allows for better support of the first screen portion, improving the screen's reliability. Furthermore, the large area of ​​the reinforcing plate ensures that all external light entering the non-display side space of the screen through the light-transmitting area can pass through the reinforcing plate, resulting in a consistent or similar optical path environment. This reduces the risk of image distortion in the optical devices and improves the light-gathering quality of the optical devices.

[0023] In some possible implementations, the screen also includes an adhesive component located between the reinforcing plate and the first inner surface, and fixedly connecting the reinforcing plate and the first inner surface. The adhesive component allows external light to pass through. In this case, the adhesive component is fixedly connected to the first surface of the reinforcing plate. The reinforcing plates are stacked and fixed to the first inner surface of the first screen portion. The reinforcing plates can directly reinforce the first screen portion, resulting in good reinforcement. Furthermore, the compact arrangement of the reinforcing plates and the first screen portion is beneficial for controlling the thickness of the light-transmitting area of ​​the screen. When the position of the optical components is the bottleneck of the overall thickness of the electronic device, it can effectively control the overall thickness of the electronic device, which is conducive to achieving the thinning of the electronic device.

[0024] 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 a transparent optical adhesive or a pressure-sensitive adhesive.

[0025] In some possible implementations, the surface of the second screen facing the groove is the sidewall of the groove, and a gap is formed between the peripheral side of the reinforcing plate and the sidewall of the groove.

[0026] In this embodiment, the gap between the peripheral side of the reinforcing plate and the side wall of the groove is the assembly gap. By providing this assembly gap, the risk of damage to the display screen by the reinforcing plate can be reduced, thereby protecting the display screen.

[0027] In some possible implementations, the display screen includes a light-shielding layer in a ring shape. The light-shielding layer is at least partially located in the first screen portion, covering the gap and the periphery of the reinforcing plate in the thickness direction of the screen, and 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, it can be an ink layer.

[0028] In this embodiment, by using a light-shielding layer to block the gap between the reinforcing plate and the sidewall of the groove, as well as the periphery of the reinforcing plate, the appearance of the screen can be improved. Furthermore, the light-shielding layer can absorb stray light, reducing stray light in the light-collecting path of the optical device, thereby improving the light-collecting quality of the optical device. The stray light can be, but is not limited to, light emitted from the display screen, or light emitted from components such as flashlights inside the electronic device.

[0029] In some possible implementations, the reinforcing plate includes a plate body and a light-blocking layer. The light-blocking layer is fixed to the plate body's surface facing away from the first screen. The light transmittance of the plate body is greater than or equal to 20%. The light-blocking layer can be made of light-absorbing or light-blocking materials to block the light path. For example, the light-blocking layer can be an ink layer, which can be formed by directly coating ink onto the plate body's surface. Alternatively, the light-blocking layer can be a black film, which can be fixed to the plate body's surface by adhesive or other methods.

[0030] The light-blocking layer is ring-shaped, with its inner diameter smaller than that of the light-shielding layer and its outer diameter larger than that of the light-blocking layer. The inner space of the light-blocking layer is directly opposite the inner space of the light-shielding layer.

[0031] In this embodiment, since the surface of the reinforcing plate facing away from the first screen 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 on the surface of the plate facing away from the first screen and the optical device is small. Based on the field-of-view characteristics of the light-receiving optical device, the inner diameter of the light-blocking layer can be set to a smaller size. Consequently, the outer diameter of the light-blocking layer can be smaller, the outer diameter of the reinforcing plate can be smaller, and the opening size of the recess of the display screen can be smaller. This helps to reduce the area of ​​the non-display area of ​​the screen and increases the screen-to-body ratio.

[0032] The light-shielding layer can block the gap between the reinforcing plate and the side wall of the groove, thereby blocking the light-blocking structural differences such as ink step differences at the edge of the reinforcing plate, thus improving the appearance of the screen.

[0033] In some possible implementations, the reinforcing plate includes a plate body and a light-blocking layer, with the light-blocking layer covering the peripheral surfaces of the plate body. The light-blocking layer can be made of light-absorbing or light-blocking materials to block the light path. For example, the light-blocking layer can be an ink layer, which can be formed by directly coating ink onto the peripheral surfaces of the plate body. Alternatively, the light-blocking layer can be a black film, which can be fixed to the peripheral surfaces of the plate body by adhesive or other methods.

[0034] In this embodiment, the light-blocking layer of the reinforcing plate is disposed facing the sidewall of the groove. The light-blocking layer can absorb stray light or block the propagation of stray light, thereby reducing stray light in the light-collecting path of the optical device, reducing the risk of crosstalk, and improving the light-collecting quality of the optical device. The stray light can be, but is not limited to, light emitted from the display screen or light emitted from components such as flash lamps inside electronic devices.

[0035] 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 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, and the setting of the reinforcing plate does not increase the thickness of the screen, thus facilitating the thinning of electronic devices; furthermore, it also makes the inner surface of the screen flat, which helps to reduce the assembly difficulty of the screen and simplify the assembly structure of the screen.

[0036] In some possible implementations, the sum of the thickness of the reinforcing plate and the thickness of the adhesive is less than the depth of the groove in the thickness direction of the screen. In this case, the second surface of the reinforcing plate is recessed relative to the second inner surface of the second screen portion, and the setting of the reinforcing plate does not increase the thickness of the screen, thus facilitating the thinning of electronic devices.

[0037] In some possible implementations, the reinforcing plate includes a first plate and a second plate, with the second plate fixed to the middle of the first plate. The first plate is part of the main plate, and the second plate is another part; the first and second plates can be stacked. The first and second plates can be integrally formed structural components. Both the first and second plates have a light transmittance greater than or equal to 20%.

[0038] In this design, the second plate is at least partially located within 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 using an adhesive layer.

[0039] In this embodiment, the light-transmitting area of ​​the screen can be positioned corresponding to the middle of the first screen portion, the first plate, and the second plate. This light-transmitting area has high light transmittance, facilitating light collection by optical devices located on the non-display side of the screen. Since the first and second plates are stacked with the first screen portion, and the second plate is at least partially located within the recess, the reinforcing plate increases the structural strength of the first screen portion and its surroundings, thereby improving the structural reliability of the screen. Furthermore, because the reinforcing plate is fixedly connected to the second screen portion, and the second screen portion is thicker, it provides a more reliable fixing structure and support, making the assembly structure of the reinforcing plate and the display screen more stable and reliable.

[0040] In some examples, the light transmittance of the reinforcing plate can be greater than or equal to 80%, which facilitates the passage of external light through the light-transmitting area of ​​the screen, thereby increasing the amount of light received by the camera module, resulting in higher image quality and reducing the risk of stray light and ghosting. The materials of the first and second plates can be polymer materials or optical glass.

[0041] In some possible implementations, the surface of the second screen facing the groove is the sidewall of the groove, and a gap is formed between the peripheral side surface of the second plate and the sidewall of the groove. In this embodiment, the gap between the peripheral side surface of the second plate and the sidewall of the groove is an assembly gap. By providing this assembly gap, the risk of damage to the display screen by the reinforcing plate can be reduced, thereby protecting the display screen.

[0042] The reinforcing plate also 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 facing away from the second plate, and in the thickness direction of the screen, it covers the gap and the periphery of the second plate. The light-blocking layer can be made of light-absorbing or light-blocking materials to block the light path. For example, the light-blocking layer can be an ink layer, which can be formed by directly coating ink onto the surface of the second plate. Alternatively, the light-blocking layer can be a black film, which can be fixed to the surface of the second plate by adhesive or other methods.

[0043] In this embodiment, by using a light-blocking layer to block the gap between the reinforcing plate and the sidewall of the groove, as well as the periphery of the second plate, the appearance of the screen can be improved. Furthermore, the light-blocking layer can absorb stray light, reducing stray light in the light-collecting path of the optical device, thereby improving the light-collecting quality of the optical device. The stray light can be, but is not limited to, light emitted from the display screen, or light emitted from components such as flashlights inside the electronic device.

[0044] In addition, the light-blocking layer is fixed to the periphery of the surface of the first plate facing away from the second plate. The light-blocking layer is close to the non-display side of the screen, and therefore also close to the optical device located on the non-display side of the screen. As a result, the distance between the light-blocking layer and the optical device is small. Based on the field-of-view characteristics of the light-receiving optical device, the inner diameter of the light-blocking layer can be set to a smaller size. Consequently, the outer diameter of the light-blocking layer can be smaller, the outer diameter of the reinforcing plate can be smaller, and the opening size of the recess of the display screen can be smaller, which is beneficial to increasing the screen ratio.

[0045] In some possible implementations, the reinforcing plate also includes a light-blocking layer that at least covers the area located within the groove on the peripheral side of the second plate. For example, the light-blocking layer can cover the peripheral side of the second plate. 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 coating ink onto the peripheral side of the second plate. Alternatively, the light-blocking layer can be a black film, which can be fixed to the peripheral side of the second plate by means of adhesive or other methods.

[0046] In this embodiment, the light-blocking layer of the reinforcing plate is disposed facing the sidewall of the groove. The light-blocking layer can absorb stray light or block the propagation of stray light, thereby reducing stray light in the light-collecting path of the optical device, reducing the risk of crosstalk, and improving the light-collecting quality of the optical device. The stray light can be, but is not limited to, light emitted from the display screen or light emitted from components such as flash lamps inside electronic devices.

[0047] In some possible implementations, the reinforcing plate may include a light-transmitting portion and a light-blocking portion, with the light-transmitting portion having a higher light transmittance than the light-blocking portion. The light-transmitting portion allows external light to pass through, while the light-blocking portion blocks external light. The light-blocking portion is arranged around the light-transmitting portion and fixed to the peripheral side of the light-transmitting portion.

[0048] The light transmittance of the light-shielding part can be less than 20%, while the light transmittance of the light-transmitting part can be greater than or equal to 20%. The light-shielding part and the light-transmitting part can be integrally molded structural components, for example, through processes such as two-color injection molding.

[0049] In some embodiments, the light-shielding part can also absorb stray light or block the propagation of stray light, thereby reducing stray light in the light-collecting path of the optical device and improving the light-collecting quality of the optical device.

[0050] Secondly, embodiments of this application also provide an electronic device, including a housing, an optical component, and a screen as described above. The screen is mounted on the housing, and the optical component is mounted on the housing and located on the non-display side of the screen. The optical component is used to collect ambient light passing through the first screen portion and the reinforcing plate.

[0051] In this embodiment, the light-transmitting area of ​​the screen has high light transmittance, resulting in high image quality for the camera module. The reinforcing plate of the screen increases the structural strength of the first screen portion, reducing the risk of deformation or damage when the first screen portion is subjected to external pressure or impact. This also reduces the risk of damage to optical components and improves the reliability of the electronic device.

[0052] In some possible implementations, the electronic device also includes a support member that abuts against the reinforcing plate and the housing.

[0053] In this embodiment, since the support member abuts between the reinforcing plate and the housing, the housing can indirectly support the reinforcing plate through the support member, thereby supporting the first screen. This further reduces the risk of deformation or damage to the first screen when subjected to external pressure or impact, and the screen and electronic equipment achieve higher reliability.

[0054] The support component can be made of a flexible material to provide support and cushioning. For example, it can be made of foam, adhesive, or tape. In this case, the support component can also absorb assembly tolerances between the screen and the housing during the assembly process of the electronic device, thereby improving the yield rate. The thickness of the support component can be in the range of 0.1mm to 0.2mm.

[0055] In some possible implementations, the support member is arranged around the light-collecting surface of the optical device. For example, the support member can be roughly ring-shaped. In this embodiment, since the support member is arranged around the incident surface of the optical device, the arrangement of the support member will not affect the light collection of the optical device. Furthermore, the support member supports the reinforcing plate in a ring shape, and the support area is evenly distributed around the periphery of the reinforcing plate, making it less prone to tilting or warping of the reinforcing plate. This ensures the consistency of the light path in the light-transmitting area of ​​the screen while reinforcing the first screen.

[0056] In some possible implementations, a support member is positioned around the receiving surface of the optics, and the support member seals the connection between the reinforcing plate and the housing. In this case, the support member can seal the gap between the housing and the reinforcing plate, thereby sealing the gap between the optics and the reinforcing plate, reducing the risk of dust falling into the incident surface of the optics, and achieving dust prevention.

[0057] In some possible implementations, the support member abuts between the second screen and the housing. In this case, the housing can indirectly support the second screen through the support member, thereby further reducing the risk of deformation or damage to the screen when subjected to external pressure or impact, resulting in higher reliability of the screen and electronic device.

[0087] This application provides a screen and an electronic device including the screen. The screen includes a display screen and a reinforcing plate. The display screen includes a first screen portion and a second screen portion, with the second screen portion surrounding or partially surrounding the first screen portion. The thickness of the first screen portion is less 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 reinforcing plate is stacked on top of the first screen portion of the display screen, with at least a portion of the reinforcing plate located in the groove. At least a portion of the first screen portion and at least a portion of the reinforcing plate allow external light to pass through, and external light can pass through the first screen portion and the reinforcing plate to enter the non-display side space of the screen.

[0088] In this embodiment, the light-transmitting area of ​​the screen is positioned corresponding to the first screen portion of the display and the portion of the reinforcing plate that allows external light to pass through, thus exhibiting high light transmittance. Furthermore, the reinforcing plate enhances the structural strength of the display at the recessed area, thereby improving the screen's reliability. Therefore, the screen in this embodiment can achieve high reliability while possessing a light-transmitting area with high light transmittance.

[0089] Among them, electronic devices can be electronic products with display functions such as mobile phones, laptops, tablets, and wearable devices. Wearable devices can be smartwatches, smart bracelets, smart glasses, etc.

[0090] Figure 1 This is a schematic diagram of the structure of an electronic device 100 in a fully open state according to an embodiment of this application. Figure 2 yes Figure 1 The diagram shows the structure of the electronic device 100 in a partially open state. Figure 3 yes Figure 1 The diagram shows the structure of the electronic device 100 in its closed state. The electronic device 100 in this embodiment is illustrated using a foldable mobile phone as an example; however, other types of electronic devices can also employ similar structures, which will not be elaborated upon further below. It should be noted that... Figure 1 The accompanying drawings below only schematically illustrate some components included in the electronic device 100; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 As well as the limitations of the accompanying figures below.

[0091] In some embodiments, such as Figures 1 to 3As shown, 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), the hinge connecting 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. 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 also 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 also include a second back cover, which may be fixedly connected to the side of the second middle frame facing away from the screen 10.

[0092] For example, screen 10 is mounted on housing 20. Screen 10 has a display function, or screen 10 may integrate display and touch sensing functions. The display function of screen 10 is used to display text, images, videos, etc. The touch sensing function of screen 10 is used to detect user touch actions to achieve human-computer interaction. Screen 10 has a display side and a non-display side arranged opposite each other; the display side of screen 10 is the side that emits light to achieve display. In this embodiment, the display side of screen 10 faces the outside of electronic device 100, and the non-display side of screen 10 faces the inside of electronic device 100.

[0093] The screen 10 can be a flexible screen that can be bent to deform with the housing 20. For example, the screen 10 may include a first part 101, a second part 102, and a third part 103, with the third part 103 connected between the first part 101 and the second part 102, that is, the first part 101, the third part 103, and the second part 102 are arranged in sequence. The first part 101 can be fixed to the first housing 201, and the second part 102 can be fixed to the second housing 202. During the relative unfolding or folding of the first housing 201 and the second housing 202, the first housing 201 drives the first part 101 to move, the second housing 202 drives the second part 102 to move, and the third part 103 deforms under the action of the first part 101, the second part 102, and the housing 20.

[0094] like Figure 1As shown, the first shell portion 201 and the second shell portion 202 can be unfolded to a fully open state, with both the shell 20 and the electronic device 100 in a fully open state, and the screen 10 unfolding along with the shell 20. For example, when the shell 20 is in the fully open state, the included angle between the first shell portion 201 and the second shell portion 202 is 100°, 120°, 150°, 165°, 180°, etc. In this embodiment, the included angle between the first shell portion 201 and the second shell portion 202 is 180° as an example. At this time, the screen 10 is in a flattened state, and the first part 101, the third part 103, and the second part 102 of the screen 10 are located on the same plane.

[0095] like Figure 3 As shown, the first shell portion 201 and the second shell portion 202 can be folded relative to each other to a closed state, so that both the shell 20 and the electronic device 100 are in a closed state, and the screen 10 folds along with the shell 20. For example, when the shell 20 is in a closed state, 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 wrapped by the shell 20. Figure 3 Since screen 10 is obscured by housing 20, it is not shown. It is understood that when the first housing portion 201 and the second housing portion 202 are in the closed state, the included angle between them can be approximately 0°. When screen 10 is in the closed state, the first portion 101 and the second portion 102 of screen 10 are positioned opposite each other, and they can partially abut against each other, completely abut against each other, or have a small gap between them; the third portion 103 is in a fully bent state.

[0096] like Figure 2 As shown, the first housing portion 201 and the second housing portion 202 can also be unfolded or folded relative to each other 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 a fully open state and a 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 in a partially bent state.

[0097] In this embodiment, the screen 10 can be unfolded or folded along with the housing 20. When the electronic device 100 is fully open, the screen 10 is flat and can display in full screen, giving the electronic device 100 a larger display area to improve the user's viewing and operating experience. When the electronic device 100 is closed, its planar dimensions are small, making it easy for users to carry and store. When the electronic device 100 is partially open, a portion of the screen 10 is bent, which can meet the user's viewing needs from different angles.

[0098] In some embodiments, such as Figure 1 and Figure 2 As shown, the electronic device 100 may further include an optical element 30, which is mounted on the housing 20. The optical element 30 may be located on the non-display side of the screen 10 and is used to collect ambient light passing through the screen 10. In this embodiment, by placing the optical element 30 below the screen 10, an under-screen light-collecting structure is formed, enabling the screen 10 to have a larger display area and thus a higher screen-to-body ratio. Ambient light refers to light outside the electronic device 100. For example, ambient light may include light propagating outside the electronic device 100. In some embodiments, ambient light may also include light emitted by the electronic device 100 and reflected or refracted by structures or the environment outside the electronic device 100.

[0099] For example, the optical device 30 can be a camera module. The screen 10 has a light-transmitting area 10a that allows external light to pass through, and the light-transmitting area 10a can be located in the first portion 101 of the screen 10. In some examples, the camera module can be mounted on the first housing 201, located on the non-display side of the first portion 101 of the screen 10, and positioned directly 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. The end of the first housing 201 away from the second housing 202 is the top of the first housing 201, and the camera module can be mounted at the middle or two corners of the top of the first housing 201, with the light-transmitting area 10a of the screen 10 changing with the position of the camera module.

[0100] In 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 housing 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. This application does not strictly limit the specific type of the optical device 30 or the specific location of the light-transmitting area 10a. In 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 LED lamp).

[0101] In this embodiment, the optical effects (e.g., transmittance, haze, etc.) of the light-transmitting area 10a of the screen 10 affect the light-gathering quality of the optical device 30, thereby affecting the functional realization of the optical device 30. For example, when the optical device 30 is a camera module, high light-gathering quality results in high image quality. When the optical device 30 is a detection module such as an ambient light sensor, proximity sensor, or optical fingerprint sensor, high light-gathering quality results in high detection accuracy. Transmittance is the percentage of light flux passing through a transparent or semi-transparent body relative to the incident light flux. Haze is the percentage of transmitted light intensity at an angle greater than 2.5° from the incident light to the total transmitted light intensity; higher haze indicates a decrease in film gloss and transparency, especially image quality. Generally, higher transmittance results in lower haze. Therefore, in this embodiment, the light-transmitting area 10a of the screen 10 is configured with a structure having higher transmittance to improve the light-gathering quality of the optical device 30 and facilitate its functional realization.

[0102] In some embodiments, the electronic device 100 may further include multiple components (not shown in the figures), which are mainly housed inside the first housing 201 and the second housing 202. Some components may also be at least partially mounted on the hinge. This application does not impose strict limitations on this aspect. 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. 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. This application does not specifically limit the number, type, or location of the modules of the electronic device 100.

[0103] The following describes the implementation structure of the screen 10 of the electronic device 100 in some embodiments.

[0104] Figure 4 yes Figure 1 The diagram shows the structure of the screen 10 of the electronic device 100 in some embodiments. Figure 5 yes Figure 4 The diagram shows a cross-sectional view of screen 10 cut along point AA. Figure 6 yes Figure 4 An enlarged schematic diagram of the structure at point B on screen 10. Wherein, Figure 4The viewing angle of screen 10 is the angle viewed from the non-display side of screen 10. For ease of explanation, the orientation of screen 10 and its components closer to the display side of screen 10 will be defined as "outer," and the orientation closer to the non-display side of screen 10 will be defined as "inner." It should be noted that... Figure 4 The accompanying drawings below only schematically illustrate some of the components included in screen 10; the actual shape, size, position, and structure of these components are not subject to change. Figure 4 As well as the limitations of the accompanying figures below.

[0105] In some embodiments, such as Figure 4 and Figure 5 As shown, screen 10 includes a display screen 1 and a reinforcing plate 2. The display screen 1 can be a flexible, bendable display screen. For example, the 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 (MOLED) display screen, a micro light-emitting diode (MLED) display screen, or a quantum dot light-emitting diode (QLED) display screen, etc.

[0106] In some embodiments, such as Figure 5 and Figure 6As shown, the display screen 1 may include a first screen portion 11 and a second screen portion 12, with the second screen portion 12 surrounding and connected to the first screen portion 11. The first screen portion 11 and the second screen portion 12 may be integrally formed structural components. The first screen portion 11 includes a first outer surface 111 and a first inner surface 112 arranged opposite to each other, and the second screen portion 12 includes a second outer surface 121 and a second inner surface 122 arranged opposite to 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 flat display surface and good appearance consistency for the screen 10. The first inner surface 112 is recessed relative to the second inner surface 122, forming a groove 13. In this case, the thickness of the first screen portion 11 is less than the thickness of the second screen portion 12, and the aforementioned groove 13 is formed on the inner side of the first screen portion 11. The opening of the recess 13 faces the non-display side of the screen 10.

[0107] 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 full-layer structure of the display screen 1. Compared to the second screen portion 12, the first screen portion 11 of the display screen 1 can achieve fewer layers and a smaller thickness by reducing some layers and retaining others. At least a portion of the first screen portion 11 allows external light to pass through; this area is called the light-transmitting area of ​​the first screen portion 11. In this embodiment, "at least a portion" includes both a partial area and the entire area. When the screen 10 is not assembled into the electronic device 100, external light refers to light outside the screen 10. Compared to the traditional under-display camera structure where the screen has a full-layer structure, the first screen portion 11 in this embodiment has a smaller thickness and fewer layers, therefore the light-transmitting area of ​​the first screen portion 11 has a higher light transmittance.

[0108] For example, the reinforcing plate 2 is located on the side of the first inner surface 112 facing away from the first outer surface 111, and the reinforcing plate 2 is stacked and fixedly connected to the display screen 1 with the first screen portion 11. 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... Figure 5 In the embodiment shown, 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.

[0109] At least a portion of the reinforcing plate 2 allows external light to pass through; this area is called the light-transmitting area of ​​the reinforcing plate 2. External light can pass through the first screen portion 11 and the reinforcing plate 2 to enter the non-display side space of the screen 10. For example, the light-transmitting area of ​​the reinforcing plate 2 is positioned opposite to the light-transmitting area of ​​the first screen portion 11, and they overlap in the thickness direction Z of the screen 10. External light passes sequentially through the light-transmitting areas of the first screen portion 11 and the reinforcing plate 2 to enter the non-display side space of the screen 10.

[0110] In this embodiment, the light-transmitting area 10a of the screen 10 is configured to correspond to the light-transmitting area of ​​the first screen portion 11 and the light-transmitting area of ​​the reinforcing plate 2, thereby achieving a higher light transmittance. Since the reinforcing plate 2 is stacked with the first screen portion 11, the reinforcing plate 2 enhances the structural strength of the first screen portion 11, thereby improving the structural strength of the display screen 1 at the groove 13. The screen 10 is less likely to deform or be damaged when subjected to external pressure, compression, or impact, resulting in higher reliability. Furthermore, since the reinforcing plate 2 is at least partially located within 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 compressed or pressed, the deformation space in the thickness direction Z of the screen 10 is small, resulting in a better reinforcing effect of the reinforcing plate 2 on the first screen portion 11.

[0111] 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 reinforcing 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 high light transmittance and the light path environment is consistent or similar, so that the optical device 30 located below the light-transmitting area 10a of the screen 10 has better light-gathering quality.

[0112] 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 high light transmittance. In this case, the high light transmittance of the first screen portion 11 results in high light transmittance of the light-transmitting area 10a of the screen 10, thereby improving the light-gathering quality of the optical device 30. For example, 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 light transmittance of the layers of the first screen portion 11 varies depending on the light-gathering requirements of the optical device 30.

[0113] In some embodiments, the display screen 1 may include a first stack (not shown) and a second stack (not shown), with the first stack located in the first screen portion 11 and the second screen portion 12, and the second stack located in the second screen portion 12. The light transmittance of the first stack is higher than that of the second stack. That is, the first screen portion 11 retains the first stack with higher light transmittance relative to the second screen portion 12, while reducing the second stack with lower light transmittance. For example, the light transmittance of the first stack is higher than 20%, and the light transmittance of the second stack is lower than 20%.

[0114] In this embodiment, the first screen portion 11 improves overall transmittance by reducing low-transmittance layers and retaining high-transmittance layers. The first layer is one of the layers retained in the first screen portion 11, and the second layer is one of the layers reduced in the first screen portion 11 relative to the second screen portion 12. This embodiment does not limit the layers reduced in the first screen portion 11 relative to the second screen portion 12 to be all low-transmittance layers; it may include some high-transmittance layers. Nor does it limit the layers in the first screen portion 11 to be all high-transmittance layers; it also allows the first screen portion 11 to include low-transmittance layers used to achieve other functions (such as light-shielding layers used for light blocking, as described below).

[0115] The first screen portion 11 can be formed by removing part of the stacked layers in a local area through mechanical processing; alternatively, the first screen portion 11 can be formed by reducing the number of stacked layers in a local area during the manufacturing process. This application does not impose strict limitations on these methods.

[0116] In some embodiments, the light transmittance of the reinforcing plate 2 is higher than that of the second stack. For example, the area of ​​the reinforcing plate 2 that allows external light to pass through is higher than the light transmittance of the second stack. In this embodiment, the light transmittance of the reinforcing plate 2 is higher than the light transmittance of the stack reduced by the first screen portion 11, so that the overall light transmittance of the stacked structure of the first screen portion 11 and the reinforcing plate 2 is higher than the light transmittance of the second screen portion 12. The light-transmitting area 10a located in this stacked structure has a high light transmittance, which is beneficial to improving the light-gathering quality of the optical device 30.

[0117] In some embodiments, such as Figure 5 As shown, 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 arranged opposite to each other and parallel to each other. The peripheral side surface 213 surrounds and 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, and 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 manufacture, and has a low cost.

[0118] For example, the reinforcing plate 2 is parallel to the first screen portion 11. Specifically, the first surface 211 and the second surface 212 of the reinforcing plate 2 are both parallel to the first outer surface 111 of the first screen portion 11. At this time, the distortion of external light is small when passing through the first screen portion 11 and the reinforcing plate 2, so that the optical device 30 can 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 has better image quality.

[0119] For example, the main structure of the reinforcing plate 2 is a plate body 21. The plate body 21 of the reinforcing 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 reinforcing plate 2 can be adjusted according to the light-gathering requirements of the optical device 30. For example, the light transmittance of the plate body 21 of the reinforcing 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 reinforcing 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, increasing the amount of light received by the camera module, resulting in higher image quality of the camera module and reducing the risk of stray light and ghosting.

[0120] For example, the plate body 21 of the reinforcing plate 2 can be made of polymer materials or optical glass. For instance, the material of the plate body 21 of the reinforcing plate 2 can be transparent plastic, such as polyethylene terephthalate (PET), polycarbonate (PC), colorless polyimide (CPI), cycloolefin polymer (COP), triacetyl cellulose (TAC), etc. Alternatively, the material of the plate body 21 of the reinforcing plate 2 can be ultra-thin glass (UTG).

[0121] In some embodiments, such as Figure 5As shown, the screen 10 also includes an adhesive 3, which is located between the reinforcing plate 2 and the first inner surface 112, and is fixedly connected to the reinforcing plate 2 and the first inner surface 112. At this time, the adhesive 3 is fixedly connected to the first plate surface 211 of the reinforcing plate 2. The reinforcing plate 2 is fixedly attached to the first inner surface 112 of the first screen portion 11 in a stacked manner. The reinforcing plate 2 can directly reinforce the first screen portion 11, with good reinforcement effect. Moreover, the compact arrangement of the reinforcing plate 2 and the first screen portion 11 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 realizing the thinning of the electronic device 100.

[0122] The adhesive component 3 allows external light to pass through. The adhesive component 3 can be made of a material with high light transmittance. For example, the light transmittance of the adhesive component 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 the adhesive component 3 is greater than or equal to 80%. Exemplarily, the adhesive can be an optically clear adhesive (OCA) or a pressure-sensitive adhesive.

[0123] For example, such as Figure 5 As shown, 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 time, 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 setting of the reinforcing plate 2 does not increase the thickness of the screen 10, which is conducive to the thinning of the electronic device 100. In addition, it can also make the inner surface of the screen 10 flat, which helps to reduce the assembly difficulty of the screen 10 and simplify the assembly structure of the screen 10.

[0124] In some embodiments, such as Figure 5 and Figure 6 As shown, 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 is an assembly gap. By providing this assembly gap, the risk of damage to the display screen 1 by the reinforcing plate 2 can be reduced, thereby protecting the display screen 1.

[0125] Figure 7 yes Figure 1 The diagram shows a partial structural representation of screen 10 in some other embodiments. Figure 7 The viewing angle of screen 10 is the angle from the non-display side of screen 10 looking at screen 10. Figure 7The screen 10 of the embodiment may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two, and the parts that are the same will not be repeated.

[0126] In this embodiment, the shape of the reinforcing plate 2 can be implemented in various ways. The shape of the reinforcing plate 2 can be adapted as closely as possible to the shape of the groove 13 to achieve sufficient support for the first screen portion 11. For example, as Figure 6 As shown, groove 13 is a circular groove, and reinforcing plate 2 is a circular flat plate. Alternatively, as... Figure 7 As shown, 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 reinforcing plate 2 may also have six sides, four sides, twelve sides, etc. In some other embodiments, the reinforcing plate 2 may also be a flat plate structure of other shapes; the shape of the reinforcing plate 2 is not strictly limited in this application embodiment. In some other embodiments, the groove 13 may also have other shapes, such as polygons; the shape of the groove 13 is not strictly limited in this application embodiment.

[0127] In some embodiments, in the planar direction of the screen 10, the opening area of ​​the groove 13 is a first area, and the portion of the reinforcing plate 2 located within the groove 13 has a second area, the ratio of the second area to the first area being 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.

[0128] In this embodiment, since the ratio of the area of ​​the portion of the reinforcing plate 2 located within the groove 13 to the opening area of ​​the groove 13 is greater than or equal to 80%, the area of ​​the portion of the reinforcing plate 2 located within the groove 13 is relatively large. This allows for better support of the first screen portion 11, improving the reliability of the screen 10. Furthermore, the large area of ​​the reinforcing plate 2 helps ensure that when external light enters the non-display side space of the screen 10 through the light-transmitting area 10a, it can all pass through the reinforcing plate 2, resulting in a consistent or similar optical path environment. This reduces the risk of image distortion in the optical device 30 and improves the light-gathering quality of the optical device 30.

[0129] Understandably, the ratio of the second area to the first area should be as large as possible, provided that there is sufficient assembly clearance between the peripheral side 213 of the reinforcing plate 2 and the groove wall of the groove 13, in order to provide a better support environment and optical path environment.

[0130] 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 in the circumferential direction. For example, as Figure 6As shown, the sidewall 131 of the groove 13 is a cylindrical surface, and the peripheral side surface 213 of the reinforcing plate 2 is a cylindrical surface. Their centerlines coincide, and the width of the gap 132 remains constant in the circumferential direction of the reinforcing plate 2. Alternatively, the sidewall 131 of the groove 13 can also be a cylindrical surface, and the peripheral side surface 213 of the reinforcing plate 2 can also be a cylindrical surface, but their centerlines are offset, and the width of the gap 132 changes in the circumferential direction of the reinforcing plate 2. Or, as... Figure 7 As shown, the sidewall 131 of the groove 13 can be a cylindrical surface, and the peripheral 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 changes in the circumferential direction of the reinforcing plate 2. In this embodiment, the specific value and design rules of the width of the gap 132 between the peripheral side surface 213 of the reinforcing plate 2 and the sidewall 131 of the groove 13 are not strictly limited.

[0131] In some embodiments, such as Figure 5 and Figure 6 As shown, the reinforcing plate 2 also 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 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 coating ink onto 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 or other means.

[0132] 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 light-collecting path of the optical device 30, reducing the risk of crosstalk, and improving the light-collecting quality of the optical device 30. The stray light can be, but is not limited to, the light emitted by the display screen 1, or the light emitted by components such as the flash lamp inside the electronic device 100.

[0133] In some embodiments, such as Figure 5 and Figure 6As shown, 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 part 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, and exposes the middle part of the reinforcing plate 2. The light-shielding layer 14 may be made of a light-absorbing material or a light-blocking material; for example, the light-shielding layer 14 may be an ink layer. The periphery and the middle part of the reinforcing plate 2 are two regions of the reinforcing plate 2. The periphery of the reinforcing plate 2 is disposed around the middle part of the reinforcing plate 2, and there is a relative positional relationship between the two. However, the boundary position between the two is not strictly limited in this embodiment. For example, in the radial direction of the reinforcing plate 2, the width of the periphery of the reinforcing plate 2 may be greater than, equal to, or less than the width of the middle part of the reinforcing plate 2. Among them, the radial direction of the reinforcing plate 2 is parallel to the 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 surface of the reinforcing plate 2.

[0134] In this embodiment, by using the light-shielding layer 14 to block 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, the appearance of the screen 10 can be improved. Furthermore, the light-shielding layer 14 can absorb stray light, reducing stray light in the light-collecting path of the optical device 30, thereby improving the light-collecting 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 the flash lamp inside the electronic device 100.

[0135] For example, the light-shielding layer 14 can be annular. The light-shielding layer 14 includes an inner annular surface and an outer annular surface disposed opposite each other, both of which are circular. In other embodiments, the light-shielding layer 14 can also be other annular structures, such as an elliptical annular shape, a square annular shape, etc. In other embodiments, the light-shielding layer 14 can also be an irregularly shaped annular shape. For example, the shape of the inner annular surface of the light-shielding ring can be different from the shape of the outer annular surface; for example, the inner annular surface can be circular, and the outer annular surface can be square. Alternatively, the shape of the inner annular surface of the light-shielding ring can be the same as the shape of the outer annular surface, but their centers are offset. The specific shape of the light-shielding layer 14 is not strictly limited in the embodiments of this application.

[0136] For example, the distance between the inner and outer ring surfaces of the light-shielding layer 14 can be between 0.05 mm and 0.3 mm, such as 0.1 mm, 0.12 mm, 0.15 mm, 0.2 mm, etc.

[0137] Figure 8 yes Figure 1 A partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 shown in some other embodiments. Figure 8The screen 10 of the embodiment may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two, and the parts that are the same will not be repeated.

[0138] In some embodiments, such as Figure 5 As shown, the light-shielding layer 14 can be completely located within the first screen portion 11. In this case, the first screen portion 11 includes the light-shielding layer 14. In other embodiments, such as Figure 8 As shown, the light-shielding layer 14 can 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 can 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 can be regular or irregular, and this embodiment does not strictly limit this. The light-shielding layer 14 can be formed during the manufacturing process of the display screen 1.

[0139] In this embodiment, the shape and position of the light-shielding layer 14 affect the display effect of the screen 10.

[0140] Figure 9 yes Figure 4 The diagram shows a partial structural view of screen 10 from another angle. Figure 9 The viewing angle of screen 10 shown is the view from the display side of the screen looking at screen 10.

[0141] In some embodiments, such as Figure 5 and Figure 9 As shown, the screen 10 also includes a light-shielding area 10b and a display area 10c. The light-shielding area 10b is arranged around the light-transmitting area 10a, and the display area 10c is arranged around the light-shielding area 10b. Figure 9 For ease of illustration, the display area 10c is shown with a slanted filled line, the light-shielding area 10b is shown with a grid filled line, and the light-transmitting area 10a has no filled line. 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 recess 13 may not be used to display images but instead 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 inside the electronic device 100.

[0142] 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.

[0143] Figure 10 yes Figure 8The diagram shows a partial structural view of screen 10 from another angle. Figure 10 The viewing angle of screen 10 shown is the view from the display side of the screen looking at screen 10.

[0144] In other embodiments, such as Figure 8 and Figure 10 As shown, the light-shielding layer 14 is partially located in the first screen portion 11 and partially in the second screen portion 12. The position of the light-shielding area 10b varies with the light-shielding layer 14, with part of the light-shielding area 10b located in the first screen portion 11 and part in the second screen portion 12. For example, both the inner and outer annular surfaces of the light-shielding layer 14 can be circular, with their centers staggered. In this case, the light-shielding layer 14 is an irregularly shaped ring, the light-shielding area 10b corresponds to the irregularly shaped ring area, the light-transmitting area 10a is circular, and the non-display area (i.e., the area formed by the light-transmitting area 10a and the light-shielding area 10b) surrounded by the display area 10c is circular.

[0145] In this embodiment, the first screen portion 11 of the display screen 1 can have various implementation structures, for example:

[0146] In some examples, the first screen portion 11 retains the outermost 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 light-shielding layer 14, which is stacked on the inner surface of the outermost cover layer. The first screen portion 11 reduces the number of other layers compared to the second screen portion 12.

[0147] Figure 11 yes Figure 5 The diagram shown is a structural schematic of display screen 1 in some examples.

[0148] In some examples, such as Figure 11 As shown, 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 has a light-transmitting hole 1511. The protective cover plate 152 is stacked on the light-emitting side of the display panel 151, covering the light-transmitting hole 1511. The light-shielding layer 14 is fixed to the surface of the protective cover plate 152 facing the light-transmitting 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.

[0149] In this example, the portion of the protective cover 152 corresponding to the light-transmitting hole 1511 and the light-shielding layer 14 form a first screen portion 11, while the remaining portions of the protective cover 152, the adhesive layer 153, and the display panel 151 form a second screen portion 12. The protective cover 152 may include one or more layers, and the display panel 151 may include multiple layers. One layer of the protective cover 152 corresponds to the first layer mentioned above, and one layer of the display panel 151 corresponds to the second layer mentioned above. The adhesive layer 153 may be a transparent optical adhesive.

[0150] Figure 12 yes Figure 5 The diagram shown is a structural schematic of display screen 1 in some other examples.

[0151] In some examples, such as Figure 12 As shown, 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, and 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. 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, and the light-shielding layer 14 is fixed to the surface of the first portion 151a facing away from the protective cover plate 152.

[0152] In this example, the portion of the protective cover 152 corresponding to the recess 13, the portion of the adhesive layer 153 corresponding to the recess 13, the first portion 151a of the display panel 151, and the light-shielding layer 14 form the first screen portion 11. Other portions of the protective cover 152, other portions 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 layers, and the display panel 151 includes multiple layers. One layer of the protective cover 152 or the first portion 151a of the display panel 151 corresponds to the aforementioned first layer, and one layer of the second portion 151b of the display panel 151 corresponds to the aforementioned second layer. The adhesive layer 153 may be a transparent optical adhesive.

[0153] Figure 13 yes Figure 12 A schematic diagram of the internal structure of the second part 151b of the display panel 151 of the display screen 1 shown.

[0154] In some embodiments, such as Figure 13As shown, the display panel 151 can be an organic light-emitting diode (OLED) panel. The second portion 151b of the display panel 151 may include a substrate 161 (BP), a thin-film transistor (TFT) 162, a pixel define layer 163 (PDL), a pixel unit layer 164, an encapsulation layer 165, a touch panel 166 (TP), an overcoating layer 167 (OC), a connection layer 168, and a polarizer 169 (POL). In this embodiment, the polarizer 169 is the layer of the display panel 151 closest to the user. Figure 4 Two thin-film transistors 162 are shown only schematically. The number of thin-film transistors 162 in the second portion 151b of the display panel 151 is not specifically limited.

[0155] For example, substrate 161 serves as a carrier substrate for the layers above it (e.g., thin-film transistor 162). The material of substrate 161 may be polyimide (PI), polyethylene terephthalate (PET), paper, metal, ultrathin glass, etc.

[0156] like Figure 13 As shown, the thin-film transistor 162 includes a buffer layer 1621, an active layer 1622, a gate insulator (GI) 1623, an inner layer dielectric (ILD) 1611, a gate 1624, a source 1612 (S), a drain 1613 (D), a planarization layer 1614 (PLN), a first trace 1615, and a second trace 1616. Exemplarily, the interlayer dielectric 1611 includes a first interlayer dielectric 1625 and a second interlayer dielectric 1626. The source 1612 includes a first source 1627 and a second source 1629. The planarization layer 1614 includes a first planarization layer 1628 and a second planarization layer 1620.

[0157] Exemplarily, a buffer layer 1621 is disposed on a substrate 161. An active layer 1622 is disposed on the surface of the buffer layer 1621 away from the substrate 161. A gate insulating layer 1623 is disposed on the 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 the surface of the gate insulating layer 1623 away from the buffer layer 1621, and the gate 1624 and the first trace 1615 are spaced apart. A first interlayer insulating layer 1625 is disposed on the 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 the surface of the first interlayer insulating layer 1625 away from the gate insulating layer 1623. A second interlayer insulating layer 1626 is disposed on the surface of the first interlayer insulating layer 1625 away from the gate insulating layer 1623 and covers the second trace 1616.

[0158] For example, a portion of the first source 1627 and the first drain 1613 are disposed on the surface of the second interlayer insulating layer 1626 away from the first interlayer insulating layer 1625, and another portion passes 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 planarization layer 1628 is disposed on the surface of the second interlayer insulating layer 1626 away from the first interlayer insulating layer 1625 and covers a portion of the first source 1627 and a portion of the first drain 1613. A portion of the second source 1629 is disposed on the surface of the first planarization layer 1628 away from the second interlayer insulating layer 1626, and another portion passes through the first planarization layer 1628 to connect to the first source 1627. A second planarization layer 1620 is disposed on the first planarization layer 1628 and covers a portion of the second source 1629.

[0159] The above is one embodiment of the thin-film transistor 162 provided in this application. In other embodiments, the thin-film transistor 162 may only have a first source 1627, a first drain 1613, and a first planarization layer 1628. This application does not limit the specific layer structure of the thin-film transistor 162. Furthermore, the positions of the first source 1627 and the first drain 1613 can be interchanged.

[0160] like Figure 13As shown, the pixel definition layer 163 can be disposed on the surface of the second planarization layer 1620 of the thin-film transistor 162, away from the first planarization layer 1628. The pixel unit layer 164 can be used to implement display functions; the pixel unit layer 164 is also called the light-emitting device layer. The pixel unit layer 164 may include an anode 1641, a light-emitting layer 1642 (EL), and a cathode 1643, which are stacked sequentially. A portion of the anode 1641 can be disposed on the surface of the second planarization layer 1620 away from the first planarization layer 1628, and another portion can pass through the second planarization layer 1620 to connect to the second source 1629. The light-emitting layer 1642 can be disposed on the surface of the anode 1641 away from the second planarization layer 1620. The cathode 1643 can be disposed on the surface of the light-emitting layer 1642 away from the anode 1641.

[0161] Understandably, the cathode 1643 can be fabricated using a full-surface vapor deposition method; therefore, the cathode 1643 has a continuous, full-layer structure in the second part 151b. The material of the cathode 1643 can be a magnesium-silver alloy or other silver-containing alloys.

[0162] For example, the material of the light-emitting layer 1642 can be an organic material, including organic small molecule light-emitting materials, coordination light-emitting materials, and polymers.

[0163] like Figure 13 As shown, 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.

[0164] Understandably, since the material of the light-emitting layer 1642 is organic, organic materials are 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 lifespan of the light-emitting layer 1642.

[0165] Understandably, the flexible interlayer 1653 can act as a water and oxygen buffer for structures such as the thin-film transistor 162 and pixel unit layer 164 beneath the encapsulation layer 165, reducing encapsulation failures caused by foreign matter. The first encapsulation layer 1651 and the second encapsulation layer 165 can also seal the flexible interlayer 1653.

[0166] For example, the first encapsulation layer 1651 and the second encapsulation layer 1652 can be SiO2 layers or Si3N4 layers fabricated by chemical vapor deposition (CVD). The flexible interlayer 1653 can be an acrylate or cured polyester polymer organic layer formed by inkjet printing (IJP) technology.

[0167] Exemplarily, the touch panel 166 is located on the surface of the encapsulation layer 165 away from the substrate 161. A protective layer 167 is disposed on the surface of the touch panel 166 away from the pixel unit layer 164. A connecting layer 168 is disposed between the protective layer 167 and the polarizer 169. The material of the connecting layer can be pressure-sensitive adhesive (PSA).

[0168] In the second portion 151b of the display panel 151, one or more of the buffer layer 1621, gate insulating layer 1623, interlayer insulating layer 1611, planarization layer 1614, encapsulation layer 165, touch panel 166, protective layer 167, connection layer 168, and polarizer 169 may be made of a material with high light transmittance. One or more layers with high light transmittance in the second portion 151b of the display panel 151 may be simultaneously deposited 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 may include the encapsulation layer 165, touch panel 166, protective layer 167, connection layer 168, and polarizer 169, minus other layers. This application embodiment does not strictly limit the specific layers of the first portion 151a of the display panel 151.

[0169] In some other embodiments, the stacked structure of the second portion 151b of the display panel 151 may also have different implementation structures. For example, the touch panel 166 may not be included, and the relevant stacked structure of the first portion 151a of the display panel 151 may be adapted.

[0170] It is understandable that the above-mentioned example structures of display screen 1 are all described with the light-shielding layer 14 completely located in the first screen portion 11 as an example. 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 adjusted accordingly, which will not be elaborated here.

[0171] The following continues to describe the implementation structure of the screen 10 provided in the embodiments of this application in other embodiments.

[0172] The main difference between screen 10 in the following embodiments and screen 10 in the previous embodiments lies in the change of some structures of the reinforcing plate 2 and / or the change of some connection structures between the reinforcing plate 2 and the display screen 1. The following mainly describes the changed aspects, while identical or similar content will not be repeated. For example, unless otherwise stated, the structure of the display screen 1 in the following embodiments can be referred to the relevant descriptions in the previous embodiments, and the unchanged parts of the reinforcing plate 2 structure and the unchanged parts of the connection structure between the reinforcing plate 2 and the display screen 1 in the following embodiments can also be referred to the relevant descriptions in the previous embodiments.

[0173] Figure 14 yes Figure 1 A partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 shown in some other embodiments. Figure 14 The screen 10 of the embodiment may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two, and the parts that are the same will not be repeated.

[0174] In some embodiments, such as Figure 14 As shown, the reinforcing plate 2 may further include a light-blocking layer 23, which is fixed to the surface of the reinforcing plate 21 facing away from the first screen portion 11. The light-blocking layer 23 may be annular, with its inner diameter smaller than that of the light-shielding layer 14 and its outer diameter larger than that of the light-shielding layer 14. The inner space of the light-blocking layer 23 is directly opposite the inner space of the light-shielding layer 14. The light-blocking layer 23 may be made of light-absorbing or light-blocking materials to block the light path. For example, the light-blocking layer 23 may be an ink layer, which can be formed by directly coating ink onto the surface of the plate 21. Alternatively, the light-blocking layer 23 may be a black film, which can be fixed to the surface of the plate 21 by adhesive or other means.

[0175] exist Figure 14 In this embodiment, the light-transmitting area 10a and the light-shielding area 10b of the screen 10 change with the position 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 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.

[0176] In this embodiment, since the plate 21 of the reinforcing plate 2 is close to the non-display side of the screen 10 on the plate surface facing away from the first screen 11, 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 on the plate surface facing away from the first screen 11 and the optical device 30 is small. Based on the field-of-view characteristics of the light-receiving optical device 30, the inner diameter of the light-blocking layer 23 can be set to a smaller size. Consequently, the outer diameter of the light-blocking layer 23 can be smaller, the outer diameter of the reinforcing plate 2 can be smaller, and the opening size of the groove 13 of the display screen 1 can be smaller. This helps to reduce 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-blocking area 10b), and helps to increase the screen ratio of the screen 10.

[0177] The light-shielding layer 14 can block the gap 132 between the reinforcing plate 2 and the side wall 131 of the groove 13, thereby blocking the light-blocking structural differences such as the ink difference at the edge of the reinforcing plate 2, thus improving the appearance of the screen 10.

[0178] Figure 15 yes Figure 1 A partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 shown in some other embodiments. Figure 15 The screen 10 of the embodiment may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two, and the parts that are the same will not be repeated.

[0179] In some embodiments, such as Figure 15 As shown, 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 less than the depth of the groove 13. At this time, 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 setting of the reinforcing plate 2 will not increase the thickness of the screen 10, thereby facilitating the thinning of the electronic device 100.

[0180] Figure 16 yes Figure 1 The diagram shows a partial schematic of the internal structure of the screen 10 of the electronic device 100 in some other embodiments. Figure 17 yes Figure 16 The diagram shows the structure of the reinforcing plate 2 on screen 10. Figure 18 yes Figure 17 The structural schematic diagram of the reinforcing plate 2 shown at another angle. Figure 16 The screen 10 of the embodiment may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two, and the parts that are the same will not be repeated.

[0181] In some embodiments, such as Figures 16 to 18As shown, the reinforcing 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 part of the plate body 21, and the second plate body 21b is another part 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 components. In some other embodiments, the first plate body 21a and the second plate body 21b can also be connected to each other through a light-transmitting adhesive layer.

[0182] For example, the first plate 21a includes a center and a periphery. The periphery and the center of the first plate 21a are two parts of the first plate 21a. The periphery of the first plate 21a is disposed around the center of the first plate 21a, and there is a relative positional relationship between the two. However, the boundary position between the two is not strictly limited in the embodiments of this application. For example, in the radial direction of the first plate 21a, the width of the periphery of the first plate 21a can be greater than, equal to, or less than the width of the center of the first plate 21a.

[0183] 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 a circular flat plate, and the second plate 21b can also be a circular flat plate. In other embodiments, the first plate 21a and the second plate 21b can have other shapes, which are not strictly limited in this application. For example, the light transmittance of both 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.

[0184] The reinforcing plate 2 is partially located inside the groove 13 and partially located outside the groove 13. For example, the second plate 21b is at least partially located inside 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 using an adhesive layer 4.

[0185] For example, the first plate 21a may include a first plate surface 211a, which includes a center and a periphery. The periphery and the center of the first plate surface 211a constitute two regions of the first plate surface 211a. The periphery of the first plate surface 211a surrounds the center, and there is a relative positional relationship between them; however, the boundary between them is not strictly defined in this embodiment. The second plate 21b is fixed to the center 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.

[0186] In this embodiment, the light-transmitting area 10a of the screen 10 can be disposed corresponding to the middle of the first screen portion 11, the middle of the first plate 21a, and the middle 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 collect light. 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 reinforcing 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 reinforcing plate 2 is fixedly connected to the second screen portion 12, and the second screen portion 12 has a large thickness, the second screen portion 12 can provide a more reliable fixing structure and support force, making the assembly structure of the reinforcing plate 2 and the display screen 1 more stable and reliable.

[0187] In some examples, the light transmittance of the reinforcing plate 2, plate 21, can be greater than or equal to 80%, which facilitates the passage of external light through the light-transmitting area 10a of the screen 10. Thus, when the optical device 30 uses a camera module, the light transmittance setting of plate 21 helps to increase the amount of light received by the camera module, resulting in higher image quality and reducing the risk of stray light and ghosting. The materials of the first plate 21a and the second plate 21b can be polymer materials or optical glass; specific details can be found in the previous embodiments and will not be repeated here.

[0188] In some embodiments, such as Figure 16 As shown, a gap 132 is formed between the peripheral side surface 213b of the second plate body 21b of the reinforcing plate 2 and the side wall 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 side wall 131 of the groove 13 is an assembly gap. By providing this assembly gap, the risk of damage to the display screen 1 by the reinforcing plate 2 can be reduced, thereby protecting the display screen 1.

[0189] In some embodiments, such as Figure 16 and Figure 17As shown, the reinforcing 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 21a facing away from the second plate 21b. For example, the first plate 21a also includes a second plate surface 212a, which is disposed facing 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 portion of the second plate surface 212a. The periphery of the second plate surface 212a and the middle portion of the second plate surface 212a constitute two regions of the second plate surface 212a. The periphery of the second plate surface 212a surrounds the middle portion of the second plate surface 212a, and there is a relative positional relationship between them. However, the boundary position between the two is not strictly limited in this embodiment. For example, in the radial direction of the second plate surface 212a, the width of the periphery of the second plate surface 212a can be greater than, equal to, or less than the width of the middle portion of the second plate surface 212a.

[0190] For example, 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 material or a 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 coating ink onto 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 adhesive or other means.

[0191] In this embodiment, by using the light-blocking layer 23 to block 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, the appearance of the screen 10 can be improved. Furthermore, the light-blocking layer 23 can absorb stray light, reducing stray light in the light-collecting path of the optical device 30, thereby improving the light-collecting 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 the flash lamp inside the electronic device 100.

[0192] Furthermore, since the second plate surface 212a of the first plate 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 on the second plate surface 212a and the optical device 30 is small. Based on the field-of-view characteristics of the light-receiving optical device 30, the inner diameter of the light-blocking layer 23 can be set to a smaller size. Consequently, the outer diameter of the light-blocking layer 23 can be smaller, the outer diameter of the reinforcing 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 increasing the screen ratio of the screen 10.

[0193] Compared to Figure 5In this embodiment, the display screen 1 is provided with a light-shielding layer 14. In this embodiment, the display screen 1 may not have a light-shielding layer, which simplifies the manufacturing process of the display screen 1 and reduces its cost. Except for the absence of the light-shielding layer 14, the other structures of the display screen 1 can be referred to the relevant descriptions in the previous embodiments, and will not be repeated here. In addition, the display area (not shown in the figure) of the display screen 1 is set according to the second screen portion 12, and the light-shielding area (not shown in the figure) is the area between the display area and the light-transmitting area 10a.

[0194] In some embodiments, such as Figures 16 to 18 As shown, the reinforcing plate 2 also includes a light-blocking layer 22, which at least covers the area located within the groove 13 of the peripheral side surface 213b of the second plate body 21b. 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 coating ink onto 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 means of adhesive bonding or other methods.

[0195] 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 light-collecting path of the optical device 30, reducing the risk of crosstalk, and improving the light-collecting quality of the optical device 30. The stray light can be, but is not limited to, the light emitted by the display screen 1, or the light emitted by components such as the flash lamp inside the electronic device 100.

[0196] Figure 19 yes Figure 1 The diagram shows a partial schematic of the internal structure of the screen 10 of the electronic device 100 in some other embodiments. Figure 20 yes Figure 19 The structural schematic diagram of the reinforcing plate 2 shown at another angle. Figure 19 The screen 10 of the embodiment may include most of the technical features of the screen 10 of the previous embodiment. The following mainly describes the differences between the two, and the parts that are the same will not be repeated.

[0197] In some embodiments, such as Figure 19 and Figure 20As shown, the reinforcing plate 2 may include a light-transmitting portion 24 and a light-shielding portion 25, wherein the light transmittance of the light-transmitting portion 24 is higher than that of the light-shielding portion 25. The light-transmitting portion 24 is used to allow external light to pass through, and the light-shielding portion 25 is used to block external light. The light-shielding portion 25 is disposed around the light-transmitting portion 24 and 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 frustum. 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 this application embodiment.

[0198] The light transmittance of the light-shielding part 25 can be less than 20%, and the light transmittance of the light-transmitting part 24 can be greater than or equal to 20%. The light-shielding part 25 and the light-transmitting part 24 can be integrally molded structural components, for example, through processes such as two-color injection molding.

[0199] The reinforcing plate 2 is partially located within the recess 13 of the display screen 1 and partially located outside the recess 13. The light-shielding portion 25 of the reinforcing plate 2 has a peripheral surface 251 facing the sidewall 131 of the recess 13, and a gap 132 is formed between the peripheral surface 251 of the light-shielding portion 25 and the sidewall 131 of the recess 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 recess 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 using an adhesive layer 4.

[0200] In this embodiment, the light-transmitting area 10a of the screen 10 is provided corresponding to the light-transmitting portion 24 of the first screen portion 11 and the reinforcing 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 reinforcing 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 reinforcing plate 2 can be set according to the field-of-view characteristics of the light-collecting of the optical device 30, so that while meeting the light-collecting needs of the optical device 30, it has a smaller volume, which is beneficial to reducing the opening size of the recess 13 of the display screen 1 and increasing the screen-to-body ratio of the screen 10.

[0201] In some embodiments, the light-shielding part 25 can absorb stray light or block the propagation of stray light, thereby reducing stray light in the light-collecting path of the optical device 30 and improving the light-collecting quality of the optical device 30.

[0202] In some other embodiments of this application, when the depth of the recess 13 of the display screen 1 is relatively small, the reinforcing plate 2 may not be located inside the recess 13, but rather entirely outside the recess 13. The periphery of the reinforcing plate 2 is fixedly connected to the second screen portion 12, and the middle portion of the reinforcing plate 2 covers the recess 13. In this case, when the first screen portion 11 is subjected to external pressure or impact, the reinforcing plate 2 can also support the first screen portion 11, reducing the risk of damage to the first screen portion 11 and also reducing the risk of damage to the optical device 30 via the first screen portion 11.

[0203] The following section provides an example illustrating how the assembly structure of the screen 10, housing 20, and optical components 30 of the electronic device 100 is implemented:

[0204] Figure 21 yes Figure 1 The illustrated electronic device 100 is shown as a cross-sectional structural diagram with sections cut along the CC direction in some embodiments. Figure 21 The screen 10 in Figure 5 The screen 10 in the embodiment is used as an example for illustration.

[0205] In some embodiments, such as Figure 5 and Figure 21 As shown, the optical component 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 component 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 component 30 is used to collect ambient light passing through the first screen portion 11 and the reinforcing plate 2. For example, the optical component 30 may be a camera module that collects ambient light passing through the light-transmitting area 10a of the screen 10 to achieve image capture.

[0206] In this embodiment, the light-transmitting area 10a of the screen 10 has a high light transmittance, thus resulting in high imaging quality of the camera module. The reinforcing plate 2 of the screen 10 increases the structural strength of the first screen portion 11, reducing the risk of deformation or damage when the first screen portion 11 is subjected to external pressure or impact, and also reducing the risk of damage to the optical components 30, thereby improving the reliability of the electronic device 100.

[0207] In some embodiments, such as Figure 21 As shown, the electronic device 100 may further include a support member 40, which abuts against the reinforcing plate 2 and the housing 20. External light enters the optical device 30 via the incident surface 301.

[0208] In this embodiment, since the support member 40 abuts between the reinforcing plate 2 and the housing 20, the housing 20 can indirectly support the reinforcing plate 2 through the support member 40, thereby supporting the first screen 11. This further reduces the risk of deformation or damage to the first screen 11 when subjected to external pressure or impact, and the screen 10 and electronic device 100 achieve higher reliability.

[0209] The support member 40 can be made of an elastic material to provide support and cushioning. For example, the support member 40 can be made of foam, glue, tape, or other similar materials. In this case, the support member 40 can also absorb assembly tolerances between the screen 10 and the housing 20 during the assembly process of the electronic device 100, 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.

[0210] The support member 40 can be arranged around the incident surface 301 of the optical device 30. The support member 40 can be approximately ring-shaped. 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 light-receiving of the optical device 30. Furthermore, the support member 40 is ring-shaped for the support area of ​​the reinforcing plate 2, and the support area is evenly distributed around the periphery of the reinforcing plate 2, making it less prone to tilting or warping of the reinforcing plate 2. This ensures the consistency of the light path of the light-transmitting area 10a of the screen 10 while reinforcing the first screen portion 11.

[0211] For example, the support member 40 seals the connection between the reinforcing plate 2 and the housing 20. In this case, 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, so as to reduce the risk of dust falling into the incident surface 301 of the optical device 30 and achieve dust prevention.

[0212] For example, the support member 40 can also abut between the second screen portion 12 and the housing 20. In this case, the housing 20 can 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, making the screen 10 and the electronic device 100 more reliable.

[0213] For example, the support member 40 may include two parts, one part abutting between the reinforcing plate 2 and the housing 20, and the other part abutting 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 some 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 arranged around the incident surface 301 of the optical device 30 and sealingly connect the second screen portion 12 and the housing 20 to achieve dust protection for the optical device 30.

[0214] In the foregoing embodiments, 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 around the incident surface 301 of the optical device 30 at intervals. The embodiments of this application do not strictly limit the specific structure or specific arrangement of the support member 40.

[0215] When the second plate surface 212 of the reinforcing plate 2 is flush with the second inner surface 122 of the second screen part 12, the assembly structure of the screen 10, the support member 40 and the shell 20 is easier to realize, with high assembly accuracy and low difficulty.

[0216] In some other embodiments, the support member 40 may be made of a light-absorbing or light-blocking material, and in the thickness direction Z of the screen 10, the support member 40 covers the gap 132 between the reinforcing plate 2 and the side wall 131 of the groove 13, as well as the periphery of the reinforcing plate 2. In this case, the display screen 1 may not have a light-shielding layer 14.

[0217] Figure 22 yes Figure 1 The illustrated electronic device 100 is shown as a cross-sectional view of the device cut along the CC direction in some other embodiments. Figure 22 The electronic device 100 of the embodiments may include most of the technical features of the electronic device 100 of the preceding embodiments. The following mainly describes the differences between the two, and the parts that are the same will not be repeated. Figure 22 The screen 10 in Figure 15 The screen 10 in the embodiment is used as an example for illustration.

[0218] 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, reducing the distance between the optical device 30 and the first screen portion 11. 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 due to the small distance between the optical device 30 and the first screen portion 11, which is beneficial to achieving a thinner electronic device 100.

[0219] For example, the support member 40 includes a first portion 401 and a second portion 402. The first portion 401 abuts between the reinforcing 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 reinforcing 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 recess 13 of the display screen 1, and the second portion 402 may be located outside the recess 13. Other designs of the support member 40 can be found in the previous embodiments and will not be described in detail here.

[0220] Figure 23 yes Figure 1 The illustrated electronic device 100 is shown as a cross-sectional view of the device cut along the CC direction in some other embodiments. Figure 23 The electronic device 100 of the embodiments may include most of the technical features of the electronic device 100 of the preceding embodiments. The following mainly describes the differences between the two, and the parts that are the same will not be repeated. Figure 23 The screen 10 in Figure 16 The screen 10 in the embodiment is used as an example for illustration.

[0221] In some embodiments, the support member 40 abuts 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 provide a sealing connection between the reinforcing plate 2 and the housing 20.

[0222] 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 housing 20 can all provide stable and reliable support, thereby improving the reliability of the screen 10.

[0223] 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.

[0224] In some other embodiments, the housing 20 has high precision, and there may be no gap or a very small gap between the housing 20 and the reinforcing plate 2, and there may also be no gap or a very small gap between the housing 20 and the portion of the second screen 12 near the groove 13. In this case, the electronic device 100 may not need to provide the aforementioned support member 40, and the housing 20 can provide support for the reinforcing plate 2 and the second screen 12.

[0225] Figure 24 yes Figure 1The illustrated electronic device 100 is shown as a cross-sectional view taken along the CC direction in some other embodiments. Figure 25 yes Figure 24 The diagram shows the structure of screen 10 from another angle. Figure 24 The electronic device 100 of the embodiment may include most of the technical features of the electronic device 100 of the preceding embodiment. The following mainly describes the differences between the two, and the parts that are the same will not be repeated.

[0226] In some embodiments, such as Figure 24 and Figure 25 As shown, the second screen portion 12 of the display screen 1 can partially surround the first screen portion 11. At this time, the first screen portion 11 of the display screen 1 and the recess 13 are located at the edge of the display screen 1, with one side of the recess 13 open. The shape of the reinforcing plate 2 can be adaptively changed according to the shape of the recess 13. A light-blocking layer 23 can be provided on the surface of the reinforcing plate 2 facing the optical device 30. Other structural designs of the reinforcing plate 2 can be referenced. Figure 14 , Figure 15 or Figure 16 Example.

[0227] In this embodiment, since the light-blocking layer 23 is disposed on the plate surface of the reinforcing 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, which in turn allows for a smaller outer diameter of the light-blocking layer 23, a smaller outer diameter of the reinforcing plate 2, and a smaller opening size of the groove 13 of the display screen 1. This is beneficial for increasing the screen-to-body ratio of the screen 10 and for reducing the width of the overall bezel of the electronic device 100, thereby improving the overall aesthetics of the device.

[0228] The support member 40 can abut against the reinforcing plate 2 and the housing 20. The support member 40 can be arranged around the incident surface 301 of the optical device 30. The support member 40 can seal the connection between the reinforcing plate 2 and the housing 20. The support member 40 can also be grounded between the second screen portion 12 of the display screen 1 and the housing 20.

[0229] Understandably, in Figures 4 to 20 In the screen 10 of the embodiments, the scheme in which the second screen portion 12 of the display screen 1 surrounds the first screen portion 11 can be changed to the scheme in which the second screen portion 12 of the display screen 1 partially surrounds the first screen portion 11. The structure of the reinforcing plate 2 and the cooperation structure between the reinforcing plate 2 and the display screen 1 remain unchanged or are adapted to form other embodiments of this application, which will not be described in detail here.

[0230] The screen 10 in the foregoing embodiments of this application can be applied to foldable electronic devices or non-foldable electronic devices, such as candybar devices or sliding devices. The screen 10 can change shape during the use of the electronic device or remain in a fixed shape; this application does not strictly limit this.

The product may still include other parts not shown in the figures. Furthermore, the actual shape, actual position, actual size and proportion, actual structure, actual quantity, etc. of the product's components or structures are not limited by the figures.

[0232] The above embodiments are used to illustrate the technical solutions of this application, and not to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.

[0233] Where there is no conflict, the embodiments and features of the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.
