Description

Technical Field

[0001] The embodiments of the present application relate to the technical field of display devices, and in particular, to a screen and an electronic device. Background Art

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

[0003] At present, there are generally two solutions for the under-screen camera structure: the first solution is that the screen structure is complete, part of the screen area forms a light-transmitting area, and the front camera is placed below the light-transmitting area. In this solution, since the light-transmitting area of ​​the screen retains all the layers of the screen and has a large thickness, the transmittance of the light-transmitting area is low, resulting in a dark shooting effect of the front camera and poor image quality. The second solution is to dig a light hole in the screen and place the front camera below the light hole. In this solution, although the front camera collects light in front of the screen through the light hole and can obtain better imaging quality, the setting of the light hole will cause the structural strength of the screen to decrease, especially for a bendable flexible screen. The structural strength of the screen at the light hole and the surrounding position is significantly reduced, and the screen is easily damaged when pressed or impacted by external force, and the reliability of the screen is poor.

[0004] Therefore, how to obtain a high light transmittance area on the screen with high reliability has become an urgent problem to be solved. Summary of the invention

[0005] The embodiments of the present application provide a screen and an electronic device. The screen has a region with high light transmittance and has high reliability.

[0006] In a first aspect, an embodiment of the present application provides a screen that can be applied to an electronic device, wherein the electronic device includes an optical device located on the non-display side of the screen. The screen includes a display screen and a reinforcement plate. The display screen includes a first screen portion and a second screen portion, and the second screen portion surrounds or semi-surrounds 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 parts.

[0007] The first screen portion includes a first outer surface and a first inner surface disposed opposite to each other, the second screen portion includes a second outer surface and a second inner surface disposed opposite to each other, the first outer surface is flush with the second outer surface, and the first inner surface is recessed relative to the second inner surface to form a groove. The thickness of the first screen portion is less than the thickness of the second screen portion.

[0008] The second screen portion of the display screen is used to display images. The second screen portion of the display screen may have a conventional display structure, which corresponds to a full-layer structure of the display screen. The first screen portion of the display screen may have fewer layers and a smaller thickness by reducing some layers and retaining some layers relative to the second screen portion.

[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 in the groove and fixedly connected to the display screen. At least a portion of the first screen portion allows external light to pass through, and at least a portion of the reinforcing plate allows 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 portion that allows external light to pass through is the light-transmitting area of ​​the first screen portion. The area of ​​the reinforcing plate that allows external light to pass through is the light-transmitting area of ​​the reinforcing plate. In some implementations, the light-transmitting area of ​​the reinforcing plate is arranged opposite to the light-transmitting area of ​​the first screen portion, and there is an overlapping area between the two in the thickness direction of the screen, and the external light passes through the light-transmitting area of ​​the first screen portion and the light-transmitting area of ​​the reinforcing plate in turn to enter the non-display side space of the screen.

[0011] In the implementation mode of the present application, the light-transmitting area of ​​the screen is arranged to correspond to the light-transmitting area of ​​the first screen portion and the light-transmitting area of ​​the reinforcement plate to obtain a higher light transmittance. Since the reinforcement plate is stacked with the first screen portion, the reinforcement plate can enhance the structural strength of the first screen portion, thereby improving the structural strength of the display screen at the groove. When the screen is subjected to external pressure, extrusion or impact, the risk of deformation or damage is relatively small, and the screen has a higher reliability. In addition, since the reinforcement plate is at least partially located in the groove, the gap between the reinforcement plate and the first screen portion is small. When the first screen portion is squeezed or pressed, the deformation space in the thickness direction of the screen is small, so that the reinforcement plate has a better reinforcement effect on the first screen portion.

[0012] Among them, in the thickness direction of the screen, the light-transmitting area of ​​the first screen part completely covers the light-transmitting area of ​​the screen, and the light-transmitting area of ​​the reinforcement plate completely covers the light-transmitting area of ​​the screen, so that the light-transmitting area of ​​the screen as a whole has a higher light transmittance, and the optical path environment is consistent or similar, so that the lighting quality of the optical device located below the light-transmitting area of ​​the screen is better.

[0013] In some embodiments, the number of stacked layers of the first screen portion of the display screen may be one or more, and most or all of the stacked layers of the first screen portion may be stacked layers with higher light transmittance. In this case, the light transmittance of the first screen portion is relatively high, so that the light transmittance of the light-transmitting area of ​​the screen is relatively high, which is beneficial to improving the lighting quality of the optical device of the electronic device. Exemplarily, the light transmittance of all or most of the stacked layers of 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, the first stack is located in the first screen portion and the second screen portion, the second stack is located in the second screen portion, and the light transmittance of the first stack is higher than the light transmittance of the second stack. That is, the first screen portion retains the first stack with a higher light transmittance relative to the second screen portion, and reduces the second stack with a 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 reduces the stacking layers with low transmittance and retains the stacking layers with high transmittance, which is beneficial to improving the overall transmittance. The first stacking layer is one of the stacking layers retained by the first screen portion, and the second stacking layer is one of the stacking layers reduced by the first screen portion relative to the second screen portion. The embodiment of the present application does not limit the stacking layers reduced by the first screen portion relative to the second screen portion to all stacking layers with low transmittance, but may also include some stacking layers with high transmittance. It is also not limited to all stacking layers of the first screen portion to be stacking layers with high transmittance, and the first screen portion is also allowed to include stacking layers with low transmittance for realizing other functions.

[0016] In some possible implementations, the light transmittance of the reinforcing plate is higher than the light transmittance 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 the light transmittance of the second stack. In this embodiment, the light transmittance of the reinforcing plate is higher than the light transmittance of the stack reduced by the first screen portion, so that the overall light transmittance of the stacked structure of the first screen portion and the reinforcing plate is higher than the light transmittance of the second screen portion, and the light-transmitting area located at the stacked structure has a higher light transmittance, which is conducive to improving the lighting quality of the optical device.

[0017] In some embodiments, the reinforcing plate is 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. The first plate surface of the reinforcing plate is arranged facing the first screen portion, and the second plate surface is arranged facing away from the first screen portion. In this embodiment, the reinforcing plate has a simple structure, is easy to process, and has a low cost.

[0018] Exemplarily, the reinforcing plate is parallel to the first screen portion. Specifically, the first plate surface and the second plate surface of the reinforcing plate are both parallel to the first outer surface of the first screen portion. At this time, the distortion of external light in the process of passing through the first screen portion and the reinforcing plate is small, so that the optical device can 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 has better shooting quality.

[0019] Exemplarily, the main structure of the reinforcement plate is a plate body. Among them, the plate body of the reinforcement plate can be made of a material with high light transmittance and high structural strength. Among them, the light transmittance of the plate body of the reinforcement plate can be adjusted according to the lighting requirements of the optical device. Exemplarily, the light transmittance of the plate body of the reinforcement plate is greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc. In some examples, the light transmittance of the plate body of the reinforcement plate can be greater than or equal to 80%, which is beneficial for external light to pass through the light-transmitting area of ​​the screen to increase the amount of light received by the camera module, so that the imaging quality of the camera module is higher and the risk of stray light and ghosting is reduced.

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

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

[0022] In this embodiment, since the ratio of the area of ​​the portion of the reinforcing plate located in 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 in the groove is larger, thereby being able to better support the first screen portion and improve the reliability of the screen. In addition, since the area of ​​the reinforcing plate is larger, it is beneficial to ensure that when external light enters the non-display side space of the screen through the light-transmitting area of ​​the screen, it can pass through the reinforcing plate, and the light path environment is consistent or similar, thereby being able to reduce the risk of distortion of the image collected by the optical device and improve the lighting quality of the optical device.

[0023] In some possible implementations, the screen also includes an adhesive, which is located between the reinforcement plate and the first inner surface and fixedly connects the reinforcement plate and the first inner surface, and the adhesive allows external light to pass through. At this time, the adhesive is fixedly connected to the first board surface of the reinforcement plate. The reinforcement plate is fixed to the first inner surface of the first screen portion in a stacked manner, and the reinforcement plate can directly reinforce the first screen portion, with a good reinforcement effect. In addition, the reinforcement plate and the first screen portion are compactly arranged, which is also conducive to controlling the thickness of the light-transmitting area of ​​the screen. When the position of the optical device is the bottleneck of the overall thickness of the electronic device, the overall thickness of the electronic device can be effectively controlled, which is conducive to achieving the thinness of the electronic device.

[0024] The adhesive may be made of a material with a high light transmittance. For example, the light transmittance of the adhesive may 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 may be made of a transparent optical adhesive or a pressure-sensitive adhesive.

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

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

[0027] In some possible implementations, the display screen includes a light shielding layer, which is annular. The light shielding layer is at least partially located in the first screen portion, and in the thickness direction of the screen, the light shielding layer covers the gap and the periphery of the reinforcement plate, and exposes the middle of the reinforcement plate. The light shielding layer can be made of a light absorbing material or a light blocking material, for example, the light shielding layer can be an ink layer.

[0028] In this embodiment, the light shielding layer shields the gap between the reinforcing plate and the side wall of the groove, as well as the periphery of the reinforcing plate, so as to improve the appearance of the screen, and the light shielding layer can also absorb stray light, reduce the stray light in the lighting path of the optical device, and improve the lighting quality of the optical device. The stray light can be, but is not limited to, light emitted by a display screen, or light emitted by components such as a flash inside an electronic device.

[0029] In some possible implementations, the reinforcement plate includes a plate body and a light-blocking layer. The light-blocking layer is fixed on the plate surface of the plate body facing away from the first screen portion. The light transmittance of the plate body is greater than or equal to 20%. The light-blocking layer can be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer can be an ink layer, and the ink layer can be formed by directly applying ink to the plate surface of the plate body. Alternatively, the light-blocking layer can be a black film, and the black film can be fixed to the plate surface of the plate body by bonding or the like.

[0030] The light blocking layer is annular, the inner diameter of the light blocking layer is smaller than the inner diameter of the light shielding layer, the outer diameter of the light blocking layer is larger than the inner diameter of the light shielding layer, and the inner space of the light blocking layer faces the inner space of the light shielding layer.

[0031] In this embodiment, since the surface of the reinforcement plate facing away from the first screen portion is close to the non-display side of the screen, it is also close to the optical device located on the non-display side of the screen. Therefore, the distance between the light blocking layer on the surface of the plate body facing away from the first screen portion and the optical device is small. Based on the field of view characteristics of the optical device for collecting light, the inner diameter of the light blocking layer can be set to a smaller size, and then the outer diameter of the light blocking layer can be smaller, the outer diameter of the reinforcement plate can be smaller, and the opening size of the groove of the display screen can be smaller, which is beneficial to reducing the area of ​​the non-display area of ​​the screen and increasing the screen-to-body ratio of the screen.

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

[0033] In some possible implementations, the reinforcing plate includes a plate body and a light-blocking layer, and the light-blocking layer covers the peripheral side of the plate body. The light-blocking layer may be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer may be an ink layer, and the ink layer may be formed by directly applying ink to the peripheral side of the plate body. Alternatively, the light-blocking layer may be a black film, and the black film may be fixed to the peripheral side of the plate body by bonding or other methods.

[0034] In this embodiment, the light-blocking layer of the reinforcement plate is arranged facing the side wall of the groove, and the light-blocking layer can absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device, reducing the risk of cross-lighting, and improving the lighting quality of the optical device. The stray light can be, but is not limited to, the light emitted by the display screen, or the light emitted by components such as the flash inside the electronic device.

[0035] In some possible implementations, in the thickness direction of the screen, the sum of the thickness of the reinforcing plate and the thickness of the adhesive is equal to the depth of the groove. In this case, the second plate surface of the reinforcing plate is flush with the second inner surface of the second screen portion, and the provision of the reinforcing plate does not increase the thickness of the screen, thereby facilitating the thinning of the electronic device; and it can also make the inner surface of the screen flat, which is conducive to reducing the difficulty of assembling the screen and simplifying the assembly structure of the screen.

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

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

[0038] The second plate is at least partially located in the groove, the first plate is located outside the groove, and the periphery of the first plate is fixedly connected to the second screen. For example, the periphery of the first plate can be bonded to the second screen via an adhesive layer.

[0039] In this embodiment, the light-transmitting area of ​​the screen can be arranged corresponding to the first screen portion, the middle portion of the first plate body, and the middle portion of the second plate body, and the light-transmitting area has a high light transmittance, so as to facilitate lighting for the optical device located on the non-display side of the screen. Since the first plate body and the second plate body are stacked with the first screen portion, and the second plate body is at least partially located in the groove, the reinforcement plate can increase the structural strength of the first screen portion and its surroundings, thereby improving the structural reliability of the screen. In addition, since the reinforcement plate is fixedly connected to the second screen portion and the thickness of the second screen portion is relatively large, the second screen portion can provide a more reliable fixing structure and supporting force, so that the assembly structure of the reinforcement plate and the display screen is more stable and reliable.

[0040] In some examples, the light transmittance of the reinforcing plate can be greater than or equal to 80%, which is conducive to external light passing through the light-transmitting area of ​​the screen to increase the amount of light received by the camera module, so that the imaging quality of the camera module is higher and the risk of stray light and ghosting is reduced. The materials of the first plate and the second plate can be polymer materials or optical glass.

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

[0042] The reinforcing plate further includes a light-blocking layer, which is in a ring shape. The light-blocking layer is fixed to the periphery of the surface of the first plate body facing away from the second plate body, and in the thickness direction of the screen, the light-blocking layer covers the gap and the periphery of the second plate body. The light-blocking layer can be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer can be an ink layer, and the ink layer can be formed by directly applying ink to the second plate surface. Alternatively, the light-blocking layer can be a black film, and the black film can be fixed to the second plate surface by bonding or the like.

[0043] In this embodiment, the light-blocking layer shields the gap between the reinforcing plate and the side wall of the groove, as well as the periphery of the second plate body, so as to improve the appearance of the screen, and the light-blocking layer can also absorb stray light, reduce the stray light in the lighting path of the optical device, and improve the lighting quality of the optical device. The stray light can be, but is not limited to, light emitted by a display screen, or light emitted by components such as a flash inside an electronic device.

[0044] In addition, the light blocking layer is fixed to the periphery of the surface of the first plate body facing away from the second plate body. The light blocking layer is close to the non-display side of the screen, and therefore is also close to the optical device located on the non-display side of the screen. Therefore, the distance between the light blocking layer and the optical device is small. Based on the field of view characteristics of the optical device for collecting light, the inner diameter of the light blocking layer can be set to a smaller size, and then the outer diameter of the light blocking layer can be smaller, the outer diameter of the reinforcement plate can be smaller, and the opening size of the groove of the display screen can be smaller, which is beneficial to increase the screen-to-body ratio of the screen.

[0045] In some possible implementations, the reinforcing plate further includes a light-blocking layer, which at least covers the area of ​​the peripheral side surface of the second plate body located in the groove. For example, the light-blocking layer may cover the peripheral side surface of the second plate body. The light-blocking layer may be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer may be an ink layer, which may be formed by directly applying ink to the peripheral side surface of the second plate body. Alternatively, the light-blocking layer may be a black film, which may be fixed to the peripheral side surface of the second plate body by bonding or the like.

[0046] In this embodiment, the light-blocking layer of the reinforcement plate is arranged facing the side wall of the groove, and the light-blocking layer can absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device, reducing the risk of cross-lighting, and improving the lighting quality of the optical device. The stray light can be, but is not limited to, the light emitted by the display screen, or the light emitted by components such as the flash inside the electronic device.

[0047] In some possible implementations, the reinforcing plate may include a light-transmitting portion and a light-shielding portion, wherein the light transmittance of the light-transmitting portion is higher than the light transmittance of the light-shielding portion. The light-transmitting portion is used to allow external light to pass through, and the light-shielding portion is used to block external light. The light-shielding portion is arranged around the light-transmitting portion and is fixed to the peripheral side surface of the light-transmitting portion.

[0048] The light transmittance of the light shielding part can be less than 20%, and 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 formed structural parts, for example, they can be formed by a process such as two-color injection molding.

[0049] In some implementations, the light shielding portion may also absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device, so as to improve the lighting quality of the optical device.

[0050] In a second aspect, the present application also provides an electronic device, comprising a housing, an optical device, and any of the above screens. The screen is mounted on the housing, the optical device is mounted on the housing and is located on the non-display side of the screen, and the optical device is used to collect external light passing through the first screen portion and the reinforcement plate.

[0051] In this embodiment, the light-transmitting area of ​​the screen has a high light transmittance, so the imaging quality of the camera module is high. The reinforcing plate of the screen increases the structural strength of the first screen portion, and the risk of deformation or damage to the first screen portion when it is pressed or impacted by the outside is small, which can also reduce the risk of damage to the optical device and improve the reliability of the electronic device.

[0052] In some possible implementations, the electronic device further includes a support member, and the support member is abutted between the reinforcing plate and the housing.

[0053] In this embodiment, since the support member is abutted between the reinforcement plate and the shell, the shell can indirectly support the reinforcement plate through the support member, and then support the first screen part, so that the risk of deformation or damage of the first screen part when subjected to external pressure or impact is further reduced, and the screen and electronic device have higher reliability.

[0054] The support member may be made of elastic material to have supporting and buffering functions. For example, the support member may be made of foam, glue, tape and other materials. At this time, the support member can also absorb the assembly tolerance between the screen and the housing during the assembly process of the electronic device, thereby improving the yield of the electronic device. The thickness of the support member may be in the range of 0.1 mm to 0.2 mm.

[0055] In some possible implementations, the support member is disposed around the collection surface of the optical device. For example, the support member may be roughly annular. In this embodiment, since the support member is disposed around the incident surface of the optical device, the arrangement of the support member will not affect the lighting of the optical device, and the support area of ​​the support member for the reinforcement plate is annular, and the support area is relatively evenly arranged around the periphery of the reinforcement plate, so that the reinforcement plate is not prone to tilting, warping, etc., thereby ensuring the consistency of the light path of the light-transmitting area of ​​the screen while reinforcing the first screen portion.

[0056] In some possible implementations, the support member is disposed around the collection surface of the optical device, and the support member seals and connects the reinforcing plate to 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 optical device and the reinforcing plate, so as to reduce the risk of dust falling into the incident surface of the optical device, thereby achieving dust prevention.

[0057] In some possible implementations, the support member is in contact between the second screen portion and the housing. In this case, the housing can indirectly support the second screen portion through the support member, thereby further reducing the risk of deformation or damage of the screen when subjected to external pressure or impact, making the screen and the electronic device more reliable.

Thus, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features. "Multiple" refers to two or more than two.

[0085] "Installation" and "connection" should be understood in a broad sense. For example, "connection" can be a detachable connection or an inseparable connection; it can be a direct connection or an indirect connection through an intermediate medium. Among them, "integrally formed structural parts" means that during the process of forming one part of a structural part, the part is connected to other parts of the structural part, and does not need to be connected to other parts through further processing (such as bonding, welding, clamping, etc.).

[0086] The directional terms mentioned in the embodiments of the present application, such as "upper", "lower", "inner", "outer", etc., are only references to the directions of the drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present application, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the embodiments of the present application.

[0087] An embodiment of the present application provides a screen and an electronic device including the screen. The screen includes a display screen and a reinforcement plate. The display screen includes a first screen portion and a second screen portion, and the second screen portion surrounds or semi-surrounds the first screen portion. The thickness of the first screen portion is smaller than that of the second screen portion, and the inner side of the first screen portion is recessed relative to the second screen portion to form a groove. The reinforcement plate is stacked with the first screen portion of the display screen, and the reinforcement plate is at least partially located in the groove. At least a portion of the first screen portion allows external light to pass through, and at least a portion of the reinforcement plate allows external light to pass through, and external light can pass through the first screen portion and the reinforcement plate and enter the non-display side space of the screen.

[0088] In the embodiment of the present application, the light-transmitting area of ​​the screen corresponds to the first screen portion of the display screen and the portion of the reinforcement plate that allows external light to pass through, and has a high light transmittance. In addition, the reinforcement plate can enhance the structural strength of the display screen at the groove, thereby improving the reliability of the screen. Therefore, the screen of the embodiment of the present application can have a high reliability while having a light-transmitting area with a high light transmittance.

[0089] Among them, electronic devices can be mobile phones, laptops, tablet computers, wearable devices and other electronic products with display functions, and wearable devices can be smart watches, smart bracelets, smart glasses and the like.

[0090] Figure 1 is a structural diagram of an electronic device 100 provided in an embodiment of the present application when it is in a fully opened state. Figure 2 yes Figure 1 The schematic diagram of the structure of the electronic device 100 is shown in a partially opened state. Figure 3 yes Figure 1 The electronic device 100 is a schematic diagram of a structure when it is in a closed state. The electronic device 100 of the embodiment of the present application is described by taking a foldable mobile phone as an example. Of course, other types of electronic devices may also adopt a similar structure, which will not be described in detail below. It should be noted that: Figure 1 The following figures and the related drawings only schematically illustrate some components of the electronic device 100, and the actual shapes, sizes, positions and structures of these components are not subject to the present invention. Figure 1 and the accompanying drawings 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 201, a second housing 202, and a shaft (not shown in the figure), and the shaft connects the first housing 201 and the second housing 202. Through the movement of the shaft, the first housing 201 and the second housing 202 can be relatively unfolded to a fully open state or relatively folded to a closed state, and can also be relatively unfolded or relatively folded to a partially open state. Among them, the first housing 201 may include a first middle frame, and the second housing 202 may include a second middle frame. In some examples, the first housing 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 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] Exemplarily, the screen 10 is mounted on the housing 20. The screen 10 has a display function, or the screen 10 can integrate a display function and a touch sensing function. The display function of the screen 10 is used to display text, images, videos, etc. The touch sensing function of the screen 10 is used to detect the user's touch action to achieve information interaction between man and machine. The screen 10 has a display side and a non-display side that are arranged opposite to each other, and the display side of the screen 10 is the side from which the screen 10 emits light to achieve display. In this embodiment, the display side of the screen 10 faces the outside of the electronic device 100, and the non-display side of the screen 10 faces the inside of the electronic device 100.

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

[0094] like Figure 1As shown, the first shell portion 201 and the second shell portion 202 can be relatively unfolded to a fully opened state, the housing 20 and the electronic device 100 are both in a fully opened state, and the screen 10 is unfolded along with the housing 20. Exemplarily, when the housing 20 is in a fully opened state, the angle between the first shell portion 201 and the second shell portion 202 is 100°, 120°, 150°, 165°, 180°, etc., and the embodiment of the present application is described by taking the angle between the first shell portion 201 and the second shell portion 202 as 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 in 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 the housing 20 and the electronic device 100 are both in a closed state, and the screen 10 is folded along with the housing 20. Exemplarily, when the housing 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 housing 20. Figure 3 In the figure, the screen 10 is not shown because it is blocked by the housing 20. It is understandable that when the first housing 201 and the second housing 202 are in a closed state, the angle between the first housing 201 and the second housing 202 can be approximately 0°. When the screen 10 is in a closed state, the first part 101 and the second part 102 of the screen 10 are arranged opposite to each other, and the two parts can partially abut against each other, completely abut against each other, or there is a small gap, and the third part 103 is in a completely bent state.

[0096] like Figure 2 As shown, the first shell portion 201 and the second shell portion 202 can also be relatively unfolded or relatively folded to a partially open state, so that the housing 20 and the electronic device 100 are both in a partially open state. The partially open state can be any state between the fully open state and the closed state, and the screen 10 will also change accordingly. When the screen 10 is in the partially open state, an angle is formed between the first portion 101 and the second portion 102 of the screen 10, 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 with the housing 20. When the electronic device 100 is in a fully open state, the screen 10 is in a flattened state, and the screen 10 can be displayed in full screen, so that the electronic device 100 has a larger display area to improve the user's viewing experience and operating experience. When the electronic device 100 is in a closed state, the plane size of the electronic device 100 is small, which is convenient for the user to carry and store. When the electronic device 100 is in a partially open state, part of the screen 10 is bent to meet the user's viewing needs for different viewing angles.

[0098] In some embodiments, such as Figure 1 and Figure 2 As shown, the electronic device 100 may further include an optical device 30, which is mounted on the housing 20. The optical device 30 may be located on the non-display side of the screen 10, and is used to collect external light passing through the screen 10. In an embodiment of the present application, by arranging the optical device 30 below the screen 10, an under-screen lighting structure is formed, so that the screen 10 can have a larger display area to obtain a higher screen-to-body ratio. Among them, external light refers to light outside the electronic device 100. For example, the external light may include light propagating outside the electronic device 100. In some embodiments, the external light may also include light emitted by the electronic device 100 and formed after being reflected or refracted by a structure or environment outside the electronic device 100.

[0099] Exemplarily, the optical device 30 may be a camera module. The screen 10 is provided with a light-transmitting area 10a that allows external light to pass through, and the light-transmitting area 10a may be located at the first portion 101 of the screen 10. In some examples, the camera module may be mounted on the first shell portion 201, the camera module is located on the non-display side of the first portion 101 of the screen 10, and is arranged opposite the light-transmitting area 10a of the screen 10. The camera module is used to collect external light passing through the light-transmitting area 10a of the screen 10 to achieve imaging. Among them, the end of the first shell portion 201 away from the second shell portion 202 is the top of the first shell portion 201, and the camera module can be installed at the middle position or two corners of the top of the first shell portion 201, and the light-transmitting area 10a of the screen 10 changes with the position of the camera module.

[0100] In some other embodiments, the optical device 30 may also be an ambient light sensor, a proximity light sensor, or an optical fingerprint sensor. Wherein, when the optical device 30 is an optical fingerprint sensor, the fingerprint sensor may also be installed in the second shell portion 202 of the housing 20, and the light-transmitting area 10a of the screen 10 may be located in the second portion 102 of the screen 10. The specific type of the optical device 30 and the specific location of the light-transmitting area 10a are not strictly limited in the embodiments of the present application. In some other embodiments, the optical device 30 may also be an active light-emitting device such as a laser, an infrared remote control lamp (such as an infrared light-emitting diode lamp), etc.

[0101] In the embodiment of the present application, the optical effect (such as transmittance, haze, etc.) of the light-transmitting area 10a of the screen 10 affects the lighting quality of the optical device 30, and then affects the functional realization of the optical device 30. For example, when the optical device 30 is a camera module, the higher the lighting quality, the higher the imaging quality. When the optical device 30 is a detection module such as an ambient light sensor, a proximity light sensor or an optical fingerprint sensor, the higher the lighting quality, the higher the detection accuracy. Among them, the transmittance is the percentage of the luminous flux passing through a transparent or translucent body to its incident luminous flux. Haze is the percentage of the transmitted light intensity that deviates from the incident light by more than 2.5° to the total transmitted light intensity. The greater the haze, the lower the gloss and transparency of the film, especially the imaging degree. Generally, the higher the transmittance, the smaller the haze. Therefore, in the embodiment of the present application, the light-transmitting area 10a of the screen 10 is set to a structure with a higher light transmittance, so that the lighting quality of the optical device 30 is better, which is convenient for the functional realization of the optical device 30.

[0102] In some embodiments, the electronic device 100 may further include multiple components (not shown in the figure), and the multiple components are mainly housed inside the first shell 201 and the second shell 202, and some components may also be at least partially installed on the shaft, which is not strictly limited in the embodiment of the present application. 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, an earphone interface, a sensor module, a subscriber identification module (SIM) card interface, one or more rigid circuit boards or flexible circuit boards, etc. Among them, the electronic device 100 may have more or fewer components than described above, may combine two or more components, or may have different component configurations. The embodiment of the present application does not specifically limit the number, type, position, etc. of the modules of the electronic device 100.

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

[0104] Figure 4 yes Figure 1 The structure diagram of the screen 10 of the electronic device 100 in some embodiments is shown. Figure 5 yes Figure 4 The screen 10 is shown as a schematic diagram of a cross-sectional structure cut along AA. Figure 6 yes Figure 4 The enlarged schematic diagram of the structure at B of the screen 10 is shown. Figure 4The viewing angle of the screen 10 is the viewing angle from the non-display side of the screen 10 to the screen 10. For the convenience of explanation, the screen 10 and its components near the display side of the screen 10 are defined as "outside", and the non-display side of the screen 10 is defined as "inside". It should be noted that Figure 4 The following figures and the related drawings only schematically show some components of the screen 10, and the actual shapes, sizes, positions and structures of these components are not subject to Figure 4 and the accompanying drawings below.

[0105] In some embodiments, such as Figure 4 and Figure 5 As shown, the screen 10 includes a display screen 1 and a reinforcement plate 2. The display screen 1 may be a bendable flexible display screen. For example, the display screen 1 may be an organic light-emitting diode (OLED) display screen, an active-matrix organic light-emitting diode or an active-matrix organic light-emitting diode (AMOLED) display screen, a mini organic light-emitting diode (MIL-E) display screen, a micro light-emitting diode (MIL-E) display screen, a micro organic light-emitting diode (MIL-E) display screen, or a quantum dot light-emitting diode (QLED) display screen.

[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, the second screen portion 12 surrounds the first screen portion 11, and the second screen portion 12 is connected to the first screen portion 11. The first screen portion 11 and the second screen portion 12 may be integrally formed structural parts. The first screen portion 11 includes a first outer surface 111 and a first inner surface 112 disposed opposite to each other, and the second screen portion 12 includes a second outer surface 121 and a second inner surface 122 disposed opposite to each other. The first outer surface 111 and the second outer surface 121 face the display side of the screen 10, and the first inner surface 112 and the second inner surface 122 face the non-display side of the screen. The first outer surface 111 is flush with the second outer surface 121, so that the display surface of the screen 10 is flat and has a better appearance consistency. The first inner surface 112 is recessed relative to the second inner surface 122 to form a groove 13. At this time, the thickness of the first screen portion 11 is less than the thickness of the second screen portion 12, and the above-mentioned groove 13 is formed on the inner side of the first screen portion 11. The opening of the groove 13 faces the non-display side of the screen 10 .

[0107] Among them, 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, and the conventional display structure corresponds to the full-laminated structure of the display screen 1. The first screen portion 11 of the display screen 1 can reduce part of the lamination and retain part of the lamination relative to the second screen portion 12 to obtain a smaller number of laminations and a smaller thickness. Among them, at least part of the area of ​​the first screen portion 11 allows external light to pass through, and the area of ​​the first screen portion 11 that allows external light to pass through is the light-transmitting area of ​​the first screen portion 11. In the embodiment of the present application, "at least part of the area" includes two cases: part of the area and the whole area. When the screen 10 is not assembled in the electronic device 100, for the screen 10, the external light refers to the light outside the screen 10. Compared with the light-transmitting area of ​​the screen with a full-laminated structure in the traditional under-screen camera structure, the first screen portion 11 of this embodiment has a smaller thickness and a smaller number of laminations, so the light-transmitting area of ​​the first screen portion 11 has a higher light transmittance.

[0108] Exemplarily, 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 with the first screen portion 11 and fixedly connected to the display screen 1. At this time, the reinforcing plate 2 is stacked and fixed to the inner side of the first screen portion 11. Among them, the reinforcing plate 2 is at least partially located in the groove 13. For example, Figure 5 In the illustrated embodiment, the reinforcing plate 2 may be entirely located in the groove 13 ; in some other embodiments, the reinforcing plate 2 may also be partially located in the groove 13 .

[0109] Among them, at least part of the area of ​​the reinforcing plate 2 allows external light to pass through, and the area of ​​the reinforcing plate 2 that allows external light to pass through is the light-transmitting area of ​​the reinforcing plate 2. External light can pass through the first screen portion 11 and the reinforcing plate 2 and enter the non-display side space of the screen 10. For example, the light-transmitting area of ​​the reinforcing plate 2 is arranged opposite to the light-transmitting area of ​​the first screen portion 11, and there is an overlapping area between the two in the thickness direction Z of the screen 10, and the external light passes through the light-transmitting area of ​​the first screen portion 11 and the light-transmitting area of ​​the reinforcing plate 2 in sequence and enters the non-display side space of the screen 10.

[0110] In the embodiment of the present application, the light-transmitting area 10a of the screen 10 is arranged to correspond to the light-transmitting area of ​​the first screen portion 11 and the light-transmitting area of ​​the reinforcing plate 2, so as to obtain a higher light transmittance. Since the reinforcing plate 2 is stacked with the first screen portion 11, the reinforcing plate 2 can enhance the structural strength of the first screen portion 11, thereby improving the structural strength of the display screen 1 at the groove 13. When the screen 10 is subjected to external pressure, extrusion or impact, the risk of deformation or damage is small, and the screen 10 has a higher reliability. In addition, since the reinforcing plate 2 is at least partially located in the groove 13, the gap between the reinforcing plate 2 and the first screen portion 11 is small. When the first screen portion 11 is squeezed or pressed, the deformation space in the thickness direction Z of the screen 10 is small, so that the reinforcing effect of the reinforcing plate 2 on the first screen portion 11 is better.

[0111] Among them, in the thickness direction Z of the screen 10, the light-transmitting area of ​​the first screen portion 11 completely covers the light-transmitting area 10a of the screen 10, and the light-transmitting area of ​​the reinforcement plate 2 completely covers the light-transmitting area 10a of the screen 10, so that the light-transmitting area 10a of the screen 10 has a higher light transmittance as a whole, and the optical path environment is consistent or similar, so that the lighting quality of the optical device 30 located below the light-transmitting area 10a of the screen 10 is better.

[0112] In some embodiments, the number of stacked layers of the first screen portion 11 of the display screen 1 may be one or more, and most or all of the stacked layers of the first screen portion 11 may be stacked layers with a higher light transmittance. At this time, the light transmittance of the first screen portion 11 is relatively high, so that the light transmittance of the light-transmitting area 10a of the screen 10 is relatively high, which is beneficial to improving the lighting quality of the optical device 30. Exemplarily, the light transmittance of all or most of the stacked 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. Among them, the minimum value of the light transmittance of the stacked layers of the first screen portion 11 changes according to the lighting requirements of the optical device 30.

[0113] In some embodiments, the display screen 1 may include a first stack (not shown in the figure) and a second stack (not shown in the figure), the first stack is located in the first screen portion 11 and the second screen portion 12, and the second stack is located in the second screen portion 12. The light transmittance of the first stack is higher than the light transmittance of the second stack. That is, the first screen portion 11 retains the first stack with a higher light transmittance relative to the second screen portion 12, and reduces the second stack with a 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 is beneficial to improve the overall transmittance by reducing the stacking layers with low transmittance and retaining the stacking layers with high transmittance. The first stacking layer is one of the stacking layers retained by the first screen portion 11, and the second stacking layer is one of the stacking layers reduced by the first screen portion 11 relative to the second screen portion 12. The embodiment of the present application does not limit the stacking layers reduced by the first screen portion 11 relative to the second screen portion 12 to all stacking layers with low transmittance, but may also include some stacking layers with high transmittance. It is also not limited to all stacking layers of the first screen portion 11 to be stacking layers with high transmittance, and the first screen portion 11 is also allowed to include stacking layers with low transmittance for realizing other functions (such as the shading layer used for shading in the following text).

[0115] The display screen 1 can form the first screen portion 11 by removing part of the laminated layers in a local area through mechanical processing; the display screen 1 can also form the first screen portion 11 by reducing the number of laminated layers formed in a local area during the manufacturing process. This embodiment of the application does not strictly limit this.

[0116] In some embodiments, the light transmittance of the reinforcing plate 2 is higher than the light transmittance 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, and the light-transmitting area 10a located at the stacked structure has a higher light transmittance, which is beneficial to improving the lighting quality of the optical device 30.

[0117] In some embodiments, such as Figure 5 As shown, the reinforcing plate 2 is 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, and the peripheral side surface 213 surrounds and connects the first plate surface 211 and the second plate surface 212. Among them, the first plate surface 211 of the reinforcing plate 2 is arranged facing the first screen portion 11, and the second plate surface 212 is arranged facing away from the first screen portion 11. In this embodiment, the reinforcing plate 2 has a simple structure, is easy to process, and has a low cost.

[0118] Exemplarily, the reinforcing plate 2 is parallel to the first screen portion 11. Specifically, the first plate surface 211 and the second plate surface 212 of the reinforcing plate 2 are both parallel to the first outer surface 111 of the first screen portion 11. At this time, the distortion of the external light in the process of passing through the first screen portion 11 and the reinforcing plate 2 is small, 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 shooting quality.

[0119] Exemplarily, the main structure of the reinforcement plate 2 is a plate body 21. Among them, the plate body 21 of the reinforcement plate 2 can be made of a material with high light transmittance and high structural strength. Among them, the light transmittance of the plate body 21 of the reinforcement plate 2 can be adjusted according to the lighting requirements of the optical device 30. Exemplarily, the light transmittance of the plate body 21 of the reinforcement plate 2 is greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc. In some examples, the light transmittance of the plate body 21 of the reinforcement plate 2 can be greater than or equal to 80%, which is beneficial for external light to pass through the light-transmitting area 10a of the screen 10, so as to increase the amount of light received by the camera module, so that the imaging quality of the camera module is higher, and the risk of stray light and ghosting is reduced.

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

[0121] In some embodiments, such as Figure 5As shown, the screen 10 also includes an adhesive 3, which is located between the reinforcement plate 2 and the first inner surface 112, and fixedly connects the reinforcement plate 2 and the first inner surface 112. At this time, the adhesive 3 is fixedly connected to the first board surface 211 of the reinforcement plate 2. The reinforcement plate 2 is fixed to the first inner surface 112 of the first screen portion 11 in a stacked manner. The reinforcement plate 2 can directly reinforce the first screen portion 11, and the reinforcement effect is good. In addition, the reinforcement plate 2 and the first screen portion 11 are compactly arranged, which is also conducive to controlling the thickness of the light-transmitting area 10a of the screen 10. When the position of the optical device 30 is the bottleneck of the overall thickness of the electronic device 100, the overall thickness of the electronic device 100 can be effectively controlled, which is conducive to achieving the thinning of the electronic device 100.

[0122] The adhesive 3 allows external light to pass through. The adhesive 3 can be made of a material with a high light transmittance. For example, the light transmittance of the adhesive 3 can be greater than or equal to 20%, such as 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc. In some examples, the light transmittance of the adhesive 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, 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 provision 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; and it can also make the inner surface of the screen 10 flat, which is conducive to reducing the difficulty of assembling the screen 10 and simplifying 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 side wall 131 of the groove 13, and a gap 132 is formed between the peripheral side surface 213 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 213 of the reinforcing plate 2 and the side wall 131 of the groove 13 is an assembly gap. By providing the assembly gap, the risk of damage to the display screen 1 by the reinforcing plate 2 can be reduced, so as to protect the display screen 1.

[0125] Figure 7 yes Figure 1 The screen 10 shown is a partial structural schematic diagram in some other embodiments. Figure 7 The viewing angle of the screen 10 is the viewing angle from the non-display side of the screen 10 to the 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 difference between the two, and the same parts of the two will not be repeated.

[0126] In the embodiment of the present application, the shape of the reinforcing plate 2 can be realized in a variety of structures, and the shape of the reinforcing plate 2 can be adapted to the shape of the groove 13 as much as possible to fully support the first screen portion 11. Figure 6 As shown, the groove 13 is a circular groove, and the reinforcing plate 2 is a circular flat plate. Figure 7 As shown, the groove 13 is a circular groove, and the reinforcing plate 2 is a polygonal flat plate, for example, an octagonal flat plate. In some other embodiments, the number of sides of the reinforcing plate 2 may also be 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, and the embodiment of the present application does not strictly limit the shape of the reinforcing plate 2. In some other embodiments, the groove 13 may also have other shapes, such as a polygon, etc., and the embodiment of the present application does not strictly limit the shape of the groove 13.

[0127] In some embodiments, in the plane direction of the screen 10, the opening area of ​​the groove 13 is a first area, the portion of the reinforcing plate 2 located in the groove 13 has a second area, and the ratio of the second area to the first area is greater than or equal to 80%. For example, the ratio of the second area to the first area may be 82%, 84%, 85.6%, 88%, 90%, 92%, 95%, etc. The plane 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 in 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 in the groove 13 is relatively large, thereby being able to better support the first screen portion 11 and improve the reliability of the screen 10. In addition, since the area of ​​the reinforcing plate 2 is relatively large, it is beneficial to ensure that when external light enters the non-display side space of the screen 10 through the light-transmitting area 10a of the screen 10, it can pass through the reinforcing plate 2, and the light path environment is consistent or similar, thereby being able to reduce the risk of distortion of the image collected by the optical device 30 and improve the lighting quality of the optical device 30.

[0129] It is understandable that the ratio of the second area to the first area is as large as possible, while ensuring that there is sufficient assembly clearance between the peripheral side surface 213 of the reinforcement plate 2 and the groove wall of the groove 13, so as to provide a better supporting environment and optical path environment.

[0130] In some embodiments, in the circumferential direction of the reinforcing plate 2, the width of the gap 132 between the circumferential side surface 213 of the reinforcing plate 2 and the side wall 131 of the groove 13 may be constant or variable. Figure 6As shown, the side wall 131 of the groove 13 is a cylindrical surface, the peripheral side surface 213 of the reinforcing plate 2 is a cylindrical surface, the center lines of the two coincide, and the width of the gap 132 does not change in the circumferential direction of the reinforcing plate 2. Alternatively, the side wall 131 of the groove 13 can be a cylindrical surface, the peripheral side surface 213 of the reinforcing plate 2 is also a cylindrical surface, the center lines of the two are staggered, and the width of the gap 132 changes in the circumferential direction of the reinforcing plate 2. Alternatively, as Figure 7 As shown, the side wall 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 center lines of the two coincide, and the width of the gap 132 changes in the circumferential direction of the reinforcing plate 2. The embodiment of the present application does not strictly limit the specific value and design rule of the width of the gap 132 between the peripheral side surface 213 of the reinforcing plate 2 and the side wall 131 of the groove 13.

[0131] In some embodiments, such as Figure 5 and Figure 6 As shown, the reinforcing plate 2 further includes a light-blocking layer 22, which covers the peripheral side surface 213 of the plate body 21. The light-blocking layer 22 can be made of a light-absorbing material or a light-blocking material to block the light path. For example, the light-blocking layer 22 can be an ink layer, which can be formed by directly applying ink to the peripheral side surface 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 bonding or other methods.

[0132] In this embodiment, the light blocking layer 22 of the reinforcing plate 2 is disposed facing the side wall 131 of the groove 13, and the light blocking layer 22 can absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device 30, reducing the risk of cross-lighting, and improving the lighting quality of the optical device 30. The stray light may be, but is not limited to, light emitted by the display screen 1, or light emitted by components such as a flash 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, and the light shielding layer 14 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. Among them, the light shielding layer 14 can be made of light absorbing material or light blocking material, for example, the light shielding layer 14 can be an ink layer. Among them, the periphery of the reinforcing plate 2 and the middle part of the reinforcing plate 2 are two parts of the reinforcing plate 2, and the periphery of the reinforcing plate 2 is arranged around the middle part of the reinforcing plate 2. There is a relative position relationship between the two, but the embodiment of the present application does not strictly limit the boundary position between the two. For example, in the radial direction of the reinforcing plate 2, the width of the periphery of the reinforcing plate 2 can be greater than, equal to or less than the width of the middle part of the reinforcing plate 2. The radial direction of the reinforcing plate 2 is parallel to the plate surface of the reinforcing plate 2 and passes through the center line of the reinforcing plate 2 ; the center line of the reinforcing plate 2 is perpendicular to the plate surface of the reinforcing plate 2 .

[0134] In this embodiment, the light shielding layer 14 shields 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, so as to improve the appearance of the screen 10, and the light shielding layer 14 can also absorb stray light, reduce the stray light in the lighting path of the optical device 30, and improve the lighting 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 a flash inside the electronic device 100.

[0135] Exemplarily, the shading layer 14 may be in the shape of a circular ring. The shading layer 14 includes an inner ring surface and an outer ring surface that are relatively arranged, and both the inner ring surface and the outer ring surface are circular. In some other embodiments, the shading layer 14 may also be other annular structures, such as an elliptical ring shape, a square ring shape, etc. In some other embodiments, the shading layer 14 may also be a special-shaped ring. Exemplarily, the shape of the inner ring surface of the shading ring may be different from the shape of the outer ring surface, for example, the shape of the inner ring surface is circular, and the shape of the outer ring surface is square. Alternatively, the shape of the inner ring surface of the shading ring is the same as the shape of the outer ring surface, but the centers of the two are staggered. The specific shape of the shading layer 14 is not strictly limited in the embodiment of the present application.

[0136] Exemplarily, the distance between the inner annular surface and the outer annular surface of the light shielding layer 14 may be between 0.05 mm and 0.3 mm, for example, 0.1 mm, 0.12 mm, 0.15 mm, 0.2 mm, etc.

[0137] Figure 8 yes Figure 1 A partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 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 difference between the two, and the same parts of the two will not be repeated.

[0138] In some embodiments, such as Figure 5 As shown in FIG. 1 , the light shielding layer 14 may be completely located in the first screen portion 11. In this case, the first screen portion 11 includes the light shielding layer 14. In other embodiments, such as Figure 8 As shown, the light shielding layer 14 may be partially located in the first screen portion 11 and partially located in the second screen portion 12. In other words, the light shielding layer 14 may extend from the first screen portion 11 to the second screen portion 12. The shape of the portion of the light shielding layer 14 located in the second screen portion 12 may be regular or irregular, and this embodiment of the present application does not strictly limit this. The light shielding layer 14 may be formed during the preparation process of the display screen 1.

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

[0140] Fig. 9 yes Figure 4 The screen 10 is shown in a schematic diagram of a part of the structure at another angle. Fig. 9 The viewing angle of the screen 10 shown is the viewing angle from the display side of the screen to the screen 10 .

[0141] In some embodiments, such as Figure 5 and Fig. 9 As shown, the screen 10 further includes a shading area 10b and a display area 10c. The shading area 10b is arranged around the light-transmitting area 10a, and the display area 10c is arranged around the shading area 10b. Fig. 9 For the sake of convenience in illustration, the display area 10c is indicated by an inclined filling line, the shading area 10b is indicated by a grid filling line, and the light-transmitting area 10a has no filling line. Among them, the display area 10c of the screen 10 corresponds to the second screen portion 12 of the display screen 1, which is used to display images. The shading area 10b located between the display area 10c and the light-transmitting area 10a can block external light. The shading area 10b is set corresponding to the shading layer 14 of the display screen 1. In some examples, the edge portion of the second screen portion 12 of the display screen 1 close to the groove 13 may not be used to display images, but to block external light, and the shading area 10b also corresponds to this part of the structure. In some embodiments, the shading 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] Fig.10 yes Figure 8The screen 10 is shown in a schematic diagram of a part of the structure at another angle. Fig.10 The viewing angle of the screen 10 shown is the viewing angle from the display side of the screen to the screen 10 .

[0144] In other embodiments, Figure 8 and Fig.10 As shown, the light shielding layer 14 is partially located in the first screen portion 11 and partially located in the second screen portion 12, and the position of the light shielding area 10b changes with the light shielding layer 14, and the light shielding area 10b is partially located in the first screen portion 11 and partially located in the second screen portion 12. Exemplarily, the inner annular surface and the outer annular surface of the light shielding layer 14 can both be circular, and the centers of the two circles are staggered. In this case, the light shielding layer 14 is an irregular ring, the light shielding area 10b corresponds to the irregular ring area, the light-transmitting area 10a is circular, and the non-display area surrounded by the display area 10c (that is, the area formed by the light-transmitting area 10a and the light-shielding area 10b) is circular.

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

[0146] In some examples, the first screen portion 11 retains the outermost layer (cover layer) of the screen 10 compared to the second screen portion 12, that is, the layer of the screen 10 closest to the user side, and the first screen portion 11 also includes a shading layer 14, which is stacked on the inner surface of the outermost layer. The first screen portion 11 reduces the remaining layers compared to the second screen portion 12.

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

[0148] Some examples include Fig.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 is provided with a light through hole 1511. The protective cover plate 152 is stacked on the light-emitting side of the display panel 151, the protective cover plate 152 covers the light through hole 1511, and the light shielding layer 14 is fixed to the surface of the protective cover plate 152 facing the light through 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 plate 152 corresponding to the light hole 1511 and the light shielding layer 14 form the first screen portion 11, and the other portion of the protective cover plate 152, the adhesive layer 153 and the display panel 151 form the second screen portion 12. The protective cover plate 152 may include one or more laminates, and the display panel 151 includes multiple laminates. One of the laminates of the protective cover plate 152 corresponds to the first laminate mentioned above, and one of the laminates of the display panel 151 corresponds to the second laminate mentioned above. The adhesive layer 153 may be made of transparent optical glue.

[0150] Fig.12 yes Figure 5 Shown are schematic structural diagrams of the display screen 1 in other examples.

[0151] Some examples include Fig.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 adheres 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 a side of the first portion 151a facing away from the protective cover plate 152, and the light shielding layer 14 is fixed to a surface of a side 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 groove 13, the portion of the adhesive layer 153 corresponding to the groove 13, the first portion 151a of the display panel 151 and the light shielding layer 14 form the first screen portion 11, and the other portions of the protective cover 152, the 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 laminates, and the display panel 151 includes multiple laminates. One of the laminates of the first portion 151a of the protective cover 152 or the display panel 151 corresponds to the first laminate described above, and one of the laminates of the second portion 151b of the display panel 151 corresponds to the second laminate described above. The adhesive layer 153 may be made of transparent optical glue.

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

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

[0155] Exemplarily, the substrate 161 is used to provide a supporting base for the layers thereon (such as the thin film transistor 162). The material of the substrate 161 can be polyimide (PI), polyethylene terephthalate (PET), paper, metal, ultra-thin glass, etc.

[0156] like Fig.13 As shown, the thin film transistor 162 includes a buffer layer 1621 (buffer), an active layer 1622, a gate insulator 1623 (gate insulator, GI), an interlayer dielectric 1611 (inner layer dielectric, ILD), a gate 1624 (gate), a source 1612 (source, S), a drain 1613 (drain, D), a planarization layer 1614 (planarization, PLN), a first wiring 1615 and a second wiring 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, the buffer layer 1621 is disposed on the substrate 161. The active layer 1622 is disposed on the surface of the buffer layer 1621 away from the substrate 161. The 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. The gate 1624 and the first wiring 1615 are both disposed on the surface of the gate insulating layer 1623 away from the buffer layer 1621, and the gate 1624 is spaced from the first wiring 1615. The 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 wiring 1615. The second wiring 1616 is disposed on the surface of the first interlayer insulating layer 1625 away from the gate insulating layer 1623. The 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 wiring 1616.

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

[0159] The above is an implementation of the thin film transistor 162 provided by the present application. In other implementations, the thin film transistor 162 may also be provided with only the first source 1627, the first drain 1613 and the first planar layer 1628. The embodiment of the present application does not limit the specific layer structure of the thin film transistor 162. In addition, the positions of the first source 1627 and the first drain 1613 may also be swapped.

[0160] like Fig.13As shown, the pixel definition layer 163 can be arranged on the surface of the second flat layer 1620 of the thin film transistor 162 away from the first flat layer 1628. The pixel unit layer 164 can be used to realize the display function, and the pixel unit layer 164 is also called the light-emitting device layer. The pixel unit layer 164 may include an anode 1641 (anode), a light-emitting layer 1642 (emission layer, EL), and a cathode 1643 (cathode) stacked in sequence. Among them. A part of the anode 1641 can be arranged on the surface of the second flat layer 1620 away from the first flat layer 1628, and another part can pass through the second flat layer 1620 to connect the second source 1629. The light-emitting layer 1642 can be arranged on the surface of the anode 1641 away from the second flat layer 1620. The cathode 1643 can be arranged on the surface of the light-emitting layer 1642 away from the anode 1641.

[0161] It is understood that the cathode 1643 can be prepared by full-surface evaporation, so the cathode 1643 is a continuous structure in the second portion 151b. The material of the cathode 1643 can be magnesium-silver alloy or other silver-containing alloys.

[0162] For example, the material of the light-emitting layer 1642 may be an organic material, including an organic small molecule light-emitting material, a complex light-emitting material, a high molecular polymer, and the like.

[0163] like Fig.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] It is understandable that since the material of the light-emitting layer 1642 is an organic material, the organic material is easily oxidized when it comes into contact with water vapor and oxygen, resulting in failure of the light-emitting layer 1642. At this time, the encapsulation layer 165 can encapsulate the pixel unit layer 164, that is, protect the pixel unit layer 164, thereby preventing components such as water vapor and oxygen in the air from affecting the life of the light-emitting layer 1642.

[0165] It is understandable that the flexible interlayer 1653 can be used to buffer water and oxygen for the thin film transistor 162, pixel unit layer 164 and other structures below the encapsulation layer 165, thereby reducing encapsulation failure caused by foreign matter. The first encapsulation layer 1651 and the second encapsulation layer 165 can also seal the flexible interlayer 1653.

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

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

[0168] In the second part 151b of the display panel 151, one or more of the buffer layer 1621, the gate insulating layer 1623, the interlayer insulating layer 1611, the flat layer 1614, the encapsulation layer 165, the touch panel 166, the protective layer 167, the connecting layer 168, and the polarizer 169 may be made of materials with high light transmittance. One or more stacked layers with high light transmittance in the second part 151b of the display panel 151 may be simultaneously laid in the first part 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 part 151a of the display panel 151 may include the encapsulation layer 165, the touch panel 166, the protective layer 167, the connecting layer 168, and the polarizer 169, but minus other stacked layers. The embodiment of the present application does not strictly limit the specific stacked layers of the first part 151a of the display panel 151.

[0169] In some other embodiments, the stacked layers 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 related stacked layers of the first portion 151a of the display panel 151 may be adaptively changed.

[0170] It is understandable that the above-mentioned several example structures of the display screen 1 are all described by taking the case where the shading layer 14 is completely located in the first screen portion 11 as an example. When the shading layer 14 is partially located in the first screen portion 11 and partially located in the second screen portion 12, the relevant structures can be adaptively adjusted, which will not be elaborated here.

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

[0172] Among them, the main difference between the screen 10 in the following embodiment and the screen 10 in the previous embodiment is that part of the structure of the reinforcing plate 2 is changed, and / or part of the connection structure between the reinforcing plate 2 and the display screen 1 is changed. The following mainly describes the changed scheme content, and the same or similar content is not repeated. For example, unless otherwise specified, the structure of the display screen 1 in the following embodiment can refer to the relevant description of the previous embodiment, and the part of the structure of the reinforcing plate 2 that has not changed and the part of the connection structure between the reinforcing plate 2 and the display screen 1 that has not changed in the following embodiment can also refer to the relevant description of the previous embodiment.

[0173] Fig.14 yes Figure 1 A partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 in some other embodiments. Fig.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 difference between the two, and the same parts of the two will not be repeated.

[0174] In some embodiments, such as Fig.14 As shown, the reinforcement plate 2 may further include a light-blocking layer 23, which is fixed on the surface of the plate body 21 of the reinforcement plate 2 facing away from the first screen portion 11. The light-blocking layer 23 may be annular, the inner diameter of the light-blocking layer 23 is smaller than the inner diameter of the light-shielding layer 14, the outer diameter of the light-blocking layer 23 is larger than the inner diameter of the light-shielding layer 14, and the inner space of the ring of the light-blocking layer 23 is opposite to the inner space of the ring of the light-shielding layer 14. The light-blocking layer 23 may be made of light-absorbing material or light-blocking material to block the light path. For example, the light-blocking layer 23 may be an ink layer, which may be formed by directly applying ink to the surface of the plate body 21. Alternatively, the light-blocking layer 23 may be a black film, which may be fixed to the surface of the plate body 21 by bonding or the like.

[0175] exist Fig.14 In the embodiment, the light-transmitting area 10a and the light-shielding area 10b of the screen 10 change with the positions of the light-blocking layer 23 and the light-shielding layer 14. The light-transmitting area 10a of the screen 10 corresponds to the area where the inner space of the ring of the light-blocking layer 23 is located, and the light-shielding area 10b corresponds to the area where the light-blocking layer 23 and the light-shielding layer 14 are located.

[0176] In the present embodiment, since the plate surface of the plate body 21 of the reinforcement plate 2 facing away from the first screen portion 11 is close to the non-display side of the screen 10, it is also close to the optical device 30 (not shown in the figure) located on the non-display side of the screen 10. Therefore, the distance between the light blocking layer 23 located on the plate surface of the plate body 21 facing away from the first screen portion 11 and the optical device 30 is relatively small. Based on the field of view characteristics of the optical device 30 for collecting light, the inner diameter of the light blocking layer 23 can be set to a smaller size, and then the outer diameter of the light blocking layer 23 can be smaller, the outer diameter of the reinforcement plate 2 can be smaller, and the opening size of the groove 13 of the display screen 1 can be smaller, which is beneficial to 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-shielding area 10b), and is beneficial to increase the screen-to-body ratio of the screen 10.

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

Fig.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 difference between the two, and the same parts of the two will not be repeated.

[0179] In some embodiments, such as Fig.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, and the provision of the reinforcing plate 2 does not increase the thickness of the screen 10, thereby facilitating the thinning of the electronic device 100.

[0180] Fig.16 yes Figure 1 A partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 in some other embodiments, Fig.17 yes Fig.16 The structural diagram of the reinforcing plate 2 of the screen 10 is shown. Fig.18 yes Fig.17 The structure diagram of the reinforcement plate 2 shown is shown in another angle. Fig.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 difference between the two, and the same parts of the two will not be repeated.

[0181] In some embodiments, such as Figures 16 to 18As shown, the reinforcing plate 2 includes a plate body 21, and the plate body 21 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 parts. 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] Exemplarily, the first plate body 21a includes a middle portion and a periphery, the periphery of the first plate body 21a and the middle portion of the first plate body 21a are two parts of the first plate body 21a, the periphery of the first plate body 21a is arranged around the middle portion of the first plate body 21a, and there is a relative positional relationship between the two, but the embodiment of the present application does not strictly limit the boundary position between the two. For example, in the radial direction of the first plate body 21a, the width of the periphery of the first plate body 21a can be greater than, equal to, or less than the width of the middle portion of the first plate body 21a.

[0183] Wherein, the second plate body 21b is fixed to the middle part of the first plate body 21a. The outer diameter of the first plate body 21a is greater than the outer diameter of the second plate body 21b. Wherein, the first plate body 21a can be in the shape of a circular flat plate, and the second plate body 21b can also be in the shape of a circular flat plate. In some other embodiments, the first plate body 21a and the second plate body 21b can also have other shapes, which are not strictly limited in the embodiments of the present application. Exemplarily, the light transmittance of the first plate body 21a and the second plate body 21b is greater than or equal to 20%, for example, 40%, 65%, 83%, 85%, 91%, 93%, 96%, etc.

[0184] The reinforcing plate 2 is partially located in the groove 13 and partially located outside the groove 13. Exemplarily, the second plate 21b is at least partially located in the groove 13 of the display screen 1, and 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 through the adhesive layer 4.

[0185] Exemplarily, the first plate body 21a may include a first plate surface 211a, and the first plate surface 211a includes a middle portion and a periphery. The periphery of the first plate surface 211a and the middle portion of the first plate surface 211a are two regions of the first plate surface 211a, and the periphery of the first plate surface 211a is arranged around the middle portion of the first plate surface 211a. The two have a relative positional relationship, but the embodiment of the present application does not strictly limit the boundary position between the two. The second plate body 21b is fixed to the middle portion of the first plate surface 211a. The periphery of the first plate surface 211a is fixedly connected to the second screen portion 12 of the display screen 1.

[0186] In this embodiment, the light-transmitting area 10a of the screen 10 can be arranged corresponding to the first screen portion 11, the middle of the first plate 21a and the middle of the second plate 21b, and the light-transmitting area 10a has a high light transmittance, so as to facilitate the optical device 30 (not shown in the figure) located on the non-display side of the screen 10 to achieve lighting. 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, so that the structural reliability of the screen 10 is improved. In addition, since the reinforcing plate 2 is fixedly connected to the second screen portion 12 and the thickness of the second screen portion 12 is relatively large, the second screen portion 12 can provide a more reliable fixing structure and supporting force, so that the assembly structure of the reinforcing plate 2 and the display screen 1 is more stable and reliable.

[0187] In some examples, the light transmittance of the plate body 21 of the reinforcement plate 2 can be greater than or equal to 80%, so as to facilitate external light to pass through the light-transmitting area 10a of the screen 10. In this way, when the optical device 30 adopts a camera module, the light transmittance setting of the plate body 21 is conducive to increasing the amount of light received by the camera module, so that the imaging quality of the camera module is higher and the risk of stray light and ghosting is reduced. Among them, the materials of the first plate body 21a and the second plate body 21b can be polymer materials or optical glass. For details, please refer to the previous embodiment and will not be repeated here.

[0188] In some embodiments, such as Fig.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 the assembly gap, the risk of damage to the display screen 1 by the reinforcing plate 2 can be reduced, so as to protect the display screen 1.

[0189] In some embodiments, such as Fig.16 and Fig.17As shown, the reinforcing plate 2 also includes a light-blocking layer 23, and the light-blocking layer 23 is annular. The light-blocking layer 23 is fixed to the periphery of the surface of the first plate body 21a facing away from the second plate body 21b. Exemplarily, the first plate body 21a also includes a second plate surface 212a, and the second plate surface 212a is arranged 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 part of the second plate surface 212a. Among them, the periphery of the second plate surface 212a and the middle part of the second plate surface 212a are two parts of the second plate surface 212a, and the periphery of the second plate surface 212a is arranged around the middle part of the second plate surface 212a, and there is a relative position relationship between the two, but the embodiment of the present application does not strictly limit the boundary position between the two. For example, in the radial direction of the second plate surface 212a, the width of the periphery of the second plate surface 212a can be greater than, equal to or less than the width of the middle part of the second plate surface 212a.

[0190] Exemplarily, 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 body 21b. The light blocking layer 23 may be made of a light absorbing material or a light blocking material to block the light path. For example, the light blocking layer 23 may be an ink layer, which may be formed by directly applying ink to the second plate surface 212a. Alternatively, the light blocking layer 23 may be a black film, which may be fixed to the second plate surface 212a by bonding or the like.

[0191] In this embodiment, the light blocking layer 23 shields the gap 132 between the reinforcing plate 2 and the side wall 131 of the groove 13, and the periphery of the second plate 21b, so as to improve the appearance of the screen 10, and the light blocking layer 23 can also absorb stray light, reduce the stray light in the lighting path of the optical device 30, so as to improve the lighting 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 a flash inside the electronic device 100.

[0192] In addition, since the second plate surface 212a of the first plate body 21a is close to the non-display side of the screen 10, it is also close to the optical device 30 located on the non-display side of the screen 10. Therefore, the distance between the light blocking layer 23 located on the second plate surface 212a and the optical device 30 is small. Based on the field of view characteristics of the optical device 30 for collecting light, the inner diameter of the light blocking layer 23 can be set to a smaller size, and then the outer diameter of the light blocking layer 23 can be smaller, the outer diameter of the reinforcement plate 2 can be smaller, and the opening size of the groove 13 of the display screen 1 can be smaller, which is beneficial to increase the screen-to-body ratio of the screen 10.

[0193] Compared to Figure 5In the embodiment, the display screen 1 is provided with a light shielding layer 14. In this embodiment, the display screen 1 may not be provided with a light shielding layer, which simplifies the manufacturing process of the display screen 1 and reduces the cost of the display screen 1. Except for not providing the light shielding layer 14, other structures of the display screen 1 can refer to the relevant description of the previous embodiment, and will not be repeated here. In addition, the display area (not shown in the figure) of the display screen 1 is provided 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 reinforcement plate 2 also includes a light-blocking layer 22, and the light-blocking layer 22 covers at least the area of ​​the peripheral side surface 213b of the second plate body 21b located in the groove 13. For example, the light-blocking layer 22 can cover the peripheral side surface 213b of the second plate body 21b. Among them, 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, and the ink layer can be formed by directly applying ink to the peripheral side surface 213b of the second plate body 21b. Alternatively, the light-blocking layer 22 can be a black film, and the black film can be fixed to the peripheral side surface 213b of the second plate body 21b by bonding or the like.

[0195] In this embodiment, the light blocking layer 22 of the reinforcing plate 2 is disposed facing the side wall 131 of the groove 13, and the light blocking layer 22 can absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device 30, reducing the risk of cross-lighting, and improving the lighting quality of the optical device 30. The stray light may be, but is not limited to, light emitted by the display screen 1, or light emitted by components such as a flash inside the electronic device 100.

[0196] Fig.19 yes Figure 1 A partial schematic diagram of the internal structure of the screen 10 of the electronic device 100 in some other embodiments, Fig. 20 yes Fig.19 The structure diagram of the reinforcement plate 2 shown is shown in another angle. Fig.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 difference between the two, and the same parts of the two will not be repeated.

[0197] In some embodiments, such as Fig.19 and Fig. 20As shown, the reinforcing plate 2 may include a light-transmitting portion 24 and a light-shielding portion 25, and the light transmittance of the light-transmitting portion 24 is higher than the light transmittance 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 arranged around the light-transmitting portion 24 and is fixed to the peripheral side surface 241 of the light-transmitting portion 24. Exemplarily, the light-transmitting portion 24 may be in the shape of an inverted truncated cone, for example, the light-transmitting portion 24 includes a first surface 242 and a second surface 243 arranged 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, and the area of ​​the first surface 242 is larger than the second surface 243. In some other embodiments, the light-transmitting portion 24 may also be cylindrical, and the embodiments of the present application are not strictly limited to this.

[0198] The light transmittance of the shading portion 25 may be less than 20%, and the light transmittance of the transparent portion 24 may be greater than or equal to 20%. The shading portion 25 and the transparent portion 24 may be integrally formed structural parts, for example, by two-color injection molding or other processes.

[0199] Part of the reinforcing plate 2 is located in the groove 13 of the display screen 1, and part of it is located outside the groove 13. The light shielding portion 25 of the reinforcing plate 2 has a peripheral side surface 251 facing the side wall 131 of the groove 13, and a gap 132 is formed between the peripheral side surface 251 of the light shielding portion 25 and the side wall 131 of the groove 13. In the thickness direction Z of the screen 10, the light shielding portion 25 covers the above gap 132. The part of the light shielding portion 25 located outside the groove 13 is fixedly connected to the second screen portion 12 of the display screen 1. For example, the flange part of the light shielding portion 25 can be bonded to the second screen portion 12 through the adhesive layer 4.

[0200] In this embodiment, the light-transmitting area 10a of the screen 10 is arranged corresponding to the first screen portion 11 and the light-transmitting portion 24 of the reinforcement plate 2, and has a high light transmittance. The optical device 30 (not shown in the figure) located on the non-display side of the screen 10 can collect external light through the light-transmitting area 10a. The reinforcement plate 2 can increase the structural strength of the first screen portion 11 and its surroundings, making the screen 10 more reliable. In addition, the relative position of the light-shielding portion 25 and the light-transmitting portion 24 of the reinforcement plate 2 can be set according to the field of view characteristics of the optical device 30 for collecting light, so that it has a smaller volume while meeting the lighting needs of the optical device 30, which is conducive to reducing the opening size of the groove 13 of the display screen 1, and is conducive to increasing the screen-to-body ratio of the screen 10.

[0201] In some embodiments, the light shielding portion 25 can absorb stray light or block the propagation of stray light, thereby reducing the stray light entering the lighting path of the optical device 30 to improve the lighting quality of the optical device 30 .

[0202] In other embodiments of the present application, when the depth of the groove 13 of the display screen 1 is relatively small, the reinforcing plate 2 may not be located in the groove 13, but may be located entirely outside the groove 13, with the periphery of the reinforcing plate 2 fixedly connected to the second screen portion 12, and the middle of the reinforcing plate 2 covering the groove 13. In this case, when the first screen portion 11 is subjected to external pressure or impact, the reinforcing plate 2 may also support the first screen portion 11, thereby 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 is an example of an implementation method of the assembly structure of the screen 10, the housing 20 and the optical device 30 of the electronic device 100:

[0204] Fig.21 yes Figure 1 The cross-sectional structure diagram of the electronic device 100 cut along CC in some embodiments is shown. Fig.21 The screen 10 Figure 5 The screen 10 of the embodiment is taken as an example for illustration.

[0205] In some embodiments, such as Figure 5 and Fig.21 As shown, the optical device 30 of the electronic device 100 is installed in the housing 20 and is located on the non-display side of the screen 10. For example, the optical device 30 can be located on the side of the reinforcing plate 2 of the screen 10 that is away from the first screen portion 11. The optical device 30 is used to collect external light passing through the first screen portion 11 and the reinforcing plate 2. For example, the optical device 30 can be a camera module, and the camera module collects external light passing through the light-transmitting area 10a of the screen 10 to achieve shooting.

[0206] In this embodiment, the light-transmitting area 10a of the screen 10 has a high light transmittance, so the imaging quality of the camera module is high. The reinforcing plate 2 of the screen 10 increases the structural strength of the first screen portion 11. When the first screen portion 11 is pressed or impacted from the outside, the risk of deformation or damage is small, and the risk of damage to the optical device 30 is also reduced, thereby improving the reliability of the electronic device 100.

[0207] In some embodiments, such as Fig.21 As shown, the electronic device 100 may further include a support member 40, and the support member 40 is abutted between the reinforcing plate 2 and the housing 20. The external light enters the optical device 30 through the incident surface 301 of the optical device 30.

[0208] In this embodiment, since the support member 40 is abutted between the reinforcement plate 2 and the shell 20, the shell 20 can indirectly support the reinforcement plate 2 through the support member 40, and then support the first screen portion 11, so that the risk of deformation or damage of the first screen portion 11 when subjected to external pressure or impact is further reduced, and the screen 10 and the electronic device 100 obtain higher reliability.

[0209] The support member 40 may be made of an elastic material to provide support and buffer functions. For example, the support member 40 may be made of foam, glue, tape, and other materials. In this case, the support member 40 may also absorb the assembly tolerance 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 may be in the range of 0.1 mm (millimeter) to 0.2 mm.

[0210] The support member 40 may be arranged around the incident surface 301 of the optical device 30. The support member 40 may be roughly annular. In this embodiment, since the support member 40 is arranged around the incident surface 301 of the optical device 30, the arrangement of the support member 40 will not affect the lighting of the optical device 30, and the support area of ​​the support member 40 for the reinforcement plate 2 is annular, and the support area is relatively evenly arranged on the periphery of the reinforcement plate 2, so that the reinforcement plate 2 is not prone to tilting, warping, etc., so that the consistency of the light path of the light-transmitting area 10a of the screen 10 can be ensured while reinforcing the first screen portion 11.

[0211] Exemplarily, the support member 40 seals and connects the reinforcing plate 2 and the housing 20. At this time, 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, thereby achieving dust prevention.

[0212] Exemplarily, the support member 40 may also abut between the second screen portion 12 and the housing 20. In this case, the housing 20 may indirectly support the second screen portion 12 through the support member 40, thereby further reducing the risk of deformation or damage of the screen 10 when subjected to external pressure or impact, thereby making the screen 10 and the electronic device 100 more reliable.

[0213] For example, the support member 40 may include two parts, one of which abuts between the reinforcing plate 2 and the shell 20, and the other abuts between the second screen portion 12 and the shell 20. The two parts may be connected to each other or may be 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 shell 20. In this case, the part abutting between the second screen portion 12 and the shell 20 may be arranged around the incident surface 301 of the optical device 30, and the second screen portion 12 and the shell 20 are sealed to achieve dustproofing of the optical device 30.

[0214] In the aforementioned embodiment, the support member 40 is a continuous structural member. In some other embodiments, the support member 40 may also include a plurality of independent parts, which are arranged at intervals around the incident surface 301 of the optical device 30. The specific structure and specific arrangement position of the support member 40 are not strictly limited in the embodiment of the present application.

[0215] When the second plate surface 212 of the reinforcing plate 2 is flush with the second inner surface 122 of the second screen portion 12 , the assembly structure of the screen 10 , the support member 40 and the shell 20 is easier to achieve, 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 and the periphery of the reinforcing plate 2. In this case, the display screen 1 may not be provided with the light shielding layer 14.

[0217] Fig. 22 yes Figure 1 The illustrated schematic diagram is a cross-sectional structure diagram of the electronic device 100 taken along CC in some other embodiments. Fig. 22 The electronic device 100 of the embodiment may include most of the technical features of the electronic device 100 of the previous embodiment. The following mainly describes the differences between the two, and the same parts of the two are not repeated. Fig. 22 The screen 10 Fig.15 The screen 10 of the embodiment is taken as an example for illustration.

[0218] In some embodiments, 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, and the distance between the optical device 30 and the first screen portion 11 is reduced. When the position of the optical device 30 is the bottleneck of the overall thickness of the electronic device 100, since the distance between the optical device 30 and the first screen portion 11 is small, the overall thickness of the electronic device 100 can be effectively controlled, which is conducive to achieving a thinner electronic device 100.

[0219] Exemplarily, the support member 40 includes a first portion 401 and a second portion 402, wherein 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 in the groove 13 of the display screen 1, and the second portion 402 is located outside the groove 13. Other designs of the support member 40 may refer to the above embodiments and will not be described in detail here.

[0220] Fig.23 yes Figure 1 The illustrated schematic diagram is a cross-sectional structure diagram of the electronic device 100 taken along CC in some other embodiments. Fig.23 The electronic device 100 of the embodiment may include most of the technical features of the electronic device 100 of the previous embodiment. The following mainly describes the differences between the two, and the same parts of the two are not repeated. Fig.23 The screen 10 Fig.16 The screen 10 of the embodiment is taken as an example for illustration.

[0221] In some embodiments, the support member 40 is abutted between the reinforcing plate 2 and the housing 20. The support member 40 may be disposed around the incident surface 301 of the optical device 30. The support member 40 may seal and connect the reinforcing plate 2 and the housing 20.

[0222] In this embodiment, since the reinforcement 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 reinforcement 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 reinforcement plate 2, the support member 40 and the shell 20 can all provide stable and reliable support, thereby improving the reliability of the screen 10.

[0223] In the thickness direction Z of the screen 10 , there may be an overlapping area between the second screen portion 12 , the reinforcing plate 2 and the supporting member 40 , so that the supporting structure of the housing 20 for the screen 10 is more reliable.

[0224] In some other embodiments, the housing 20 has a higher precision, and there may be no gap or a very small gap between the housing 20 and the reinforcing plate 2, and there may be no gap or a very small gap between the housing 20 and the portion of the second screen portion 12 close to the groove 13. In this case, the electronic device 100 may not be provided with the above-mentioned support member 40, and the housing 20 may play a supporting role for the reinforcing plate 2 and the second screen portion 12.

Fig.25 yes Fig.24 The structure of the screen 10 shown is a schematic diagram at another angle. Fig.24 The electronic device 100 of the embodiment may include most of the technical features of the electronic device 100 of the previous embodiment. The following mainly describes the difference between the two, and the same parts of the two are not repeated.

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

[0227] In this embodiment, since the light blocking layer 23 is arranged on the plate surface of the reinforcement plate 2 facing the optical device 30, the distance between the light blocking layer 23 and the optical device 30 is small, the inner diameter of the light blocking layer 23 can be set to a smaller size, and then the outer diameter of the light blocking layer 23 can be smaller, the outer diameter of the reinforcement plate 2 can be smaller, and the opening size of the groove 13 of the display screen 1 can be smaller, which is beneficial to increase the screen-to-body ratio of the screen 10, and is also beneficial to reduce the width of the overall frame of the electronic device 100, thereby improving the aesthetics of the entire machine.

[0228] The support member 40 may be abutted between the reinforcing plate 2 and the housing 20. The support member 40 may be disposed around the incident surface 301 of the optical device 30. The support member 40 may seal and connect the reinforcing plate 2 and the housing 20. The support member 40 may also be grounded between the second screen portion 12 of the display screen 1 and the housing 20.

[0229] It is understandable that in Figures 4 to 20 In the screen 10 of the embodiment, the scheme in which the second screen portion 12 of the display screen 1 surrounds the first screen portion 11 can be changed to a scheme in which the second screen portion 12 of the display screen 1 semi-surrounds the first screen portion 11, and the structure of the reinforcement plate 2 and the matching structure between the reinforcement plate 2 and the display screen 1 remain unchanged or are adaptively changed to form other embodiment schemes of the present application, which are not described in detail here.

[0230] The screen 10 in the aforementioned embodiment of the present application can be applied to a foldable electronic device or a non-foldable electronic device, such as a straight device or a slidable device. The screen 10 can change shape during the use of the electronic device or can be in a fixed shape, which is not strictly limited in the embodiments of the present application.
