Description

Technical Field

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

[0002] Currently, users have higher and higher requirements for the configurations of electronic devices. For example, electronic devices should have a large screen-to-body ratio and integrate optical devices such as a front camera or an infrared sensor. In the related art, an electronic device includes a housing, a display screen, and an optical device. The display screen is mounted on the housing and forms a receiving space for the optical device with the housing. The display screen has a light-transmitting area opposite to the optical device. The light-transmitting area is used for the light received by the optical device to pass through, so as to realize functions such as photographing and improve the screen-to-body ratio of the electronic device. However, the light transmittance of the light-transmitting area to light is low, resulting in poor optical effects of the optical device. Summary of the Utility Model

[0003] The embodiments of the present application provide a display screen and an electronic device, which can improve the light transmittance of the area of the display screen opposite to the optical device, and improve the optical effects of the optical device.

[0004] In the first aspect of the present application, a display screen is provided. The display screen includes a cover plate, an optical adhesive layer, a display panel, a back film layer, a substrate, and a first through hole. Among them, the cover plate, the optical adhesive layer, the display panel, the back film layer, and the substrate are arranged along the thickness direction of the display screen, and the first through hole penetrates the back film layer and the substrate along the thickness direction of the display screen. The first through hole is used to be opposite to the optical device along the thickness direction of the display screen, and the optical device receives light through the first through hole.

[0005] By providing the first through hole penetrating the substrate and the back film layer, the light transmittance of the area of the display screen opposite to the optical device can be improved, the light received by the optical device can be increased, and the optical effects of the optical device can be improved. In addition, the orthographic projection of the display panel on the reference plane is a complete planar structure, that is, no through hole penetrating the display panel is provided, which improves the reliability of the area of the display screen opposite to the optical device and reduces the risk of generating black spots in this area.

[0006] In a possible implementation manner, the display screen has a light-transmitting area, and the light-transmitting area is opposite to the first through hole along the thickness direction of the display screen. The optical device receives the light passing through the light-transmitting area through the first through hole.

[0007] In this way, the light transmittance of the light passing through the light-transmitting area at the first through hole is increased, the light received by the optical device is increased, and the optical effects of the optical device are improved.

[0008] In a possible implementation, the display panel includes a first part and a second part. The thickness of the first part in the thickness direction of the display screen is less than that of the second part in the thickness direction of the display screen. The first part is opposite to the first through hole along the thickness direction of the display screen.

[0009] The fact that the thickness of the first part is less than that of the second part means that the structures of the display panel in the first part and the second part are different. The difference between the first part and the second part is that a part of the layer structure is removed from the first part, for example, a part or all of the layer structure formed by inorganic materials is removed, so that the light transmittance of the first part increases, increasing the light received by the first through hole, thereby further improving the light transmittance of the area of the display screen opposite to the optical device, and further improving the optical effect of the optical device.

[0010] In a possible implementation, the first part includes an organic layer, or the first part includes an organic layer and an inorganic layer. The second part includes an organic layer and an inorganic layer. It can be seen from this that part or all of the inorganic layer is removed from the first part, so that the light transmittance of the first part increases, thereby improving the light transmittance of the area of the display screen opposite to the optical device. In addition, the first part has at least an organic layer, so that no through hole is provided in the entire display panel, which can reduce the risk of black spots generated in the area of the display screen opposite to the optical device.

[0011] In a possible implementation, the display panel includes a display area and a peripheral area. The display area is used to display images. The peripheral area includes a first area and a second area. The first part forms the first area, a part of the second part forms the second area, and another part of the second part forms the display area. With such a setting, the integrity of the display area of the display panel can be ensured, and the page display will not be affected.

[0012] In a possible implementation, the display screen further includes a polarizer. The polarizer is disposed between the optical adhesive layer and the display panel. The orthographic projection of the first through hole on the reference plane is located inside the orthographic projection of the polarizer on the reference plane. The reference plane is the plane where the length direction and the width direction of the display screen are located.

[0013] In this way, by disposing the polarizer inside the display screen, the reflected light can be eliminated, and the display effect of the display screen can be further improved.

[0014] In a possible implementation, the display screen further includes a polarizer and a second through hole. The polarizer is disposed between the optical adhesive layer and the display panel. The second through hole penetrates the polarizer along the thickness direction of the display screen. The second through hole is opposite to the first through hole along the thickness direction of the display screen. The optical device receives the light passing through the second through hole through the first through hole.

[0015] In this way, by disposing a polarizer inside the display screen, the reflected light can be eliminated, and the display effect of the display screen can be further improved. Additionally, by providing a second through hole penetrating the polarizer, the light transmittance of the area of the display screen opposite to the optical device can be further increased, which helps to further improve the optical effect of the optical device.

[0016] In a possible implementation manner, the optical adhesive layer is connected to the display panel.

[0017] In this way, by removing the entire polarizer, the light transmittance of the area of the display screen opposite to the optical device can be further increased, which helps to further improve the optical effect of the optical device.

[0018] In a possible implementation manner, the display screen further includes an opaque first ink layer, the first ink layer is located between the cover plate and the optical adhesive layer and is respectively connected to the cover plate and the optical adhesive layer, and at least part of the first ink layer does not overlap with the orthographic projection of the first through hole on the reference plane.

[0019] In this way, by providing the first ink layer that avoids at least part of the first through hole, while ensuring that the first through hole receives light, the devices in the border area of the display screen can be blocked, improving the aesthetics of the display screen.

[0020] In a possible implementation manner, the display screen further includes a light-transmissive second ink layer, the second ink layer is located between the cover plate and the optical adhesive layer and is disposed in the same layer as the first ink layer, and the second ink layer is opposite to the first through hole along the thickness direction of the display screen.

[0021] In this way, the second ink layer can block the exposed optical device, which helps to further improve the aesthetics of the display screen. In addition, the second ink layer can allow light to pass through, enabling the optical device to receive light.

[0022] In a possible implementation manner, the display screen further includes a surface layer, and the surface layer is disposed on the side of the cover plate facing away from the optical adhesive layer along the thickness direction of the display screen.

[0023] In this way, by providing a surface layer on the surface of the cover plate, the anti-extrusion and impact resistance of the area of the display screen opposite to the optical device can be further improved.

[0024] In a possible implementation manner, the display screen further includes a display area and a border area, and the orthographic projection of the first through hole on the reference plane is located inside the orthographic projection of the border area on the reference plane, and the reference plane is the plane where the length direction and the width direction of the display screen are located. In this way, the display area of the display screen can be increased without affecting the page display.

[0025] The second aspect of the present application provides an electronic device, which includes an optical device and a display screen as described in any one of the first aspect. Among them, the optical device is arranged on the non-display side of the display screen and is opposite to the first through hole of the display screen along the thickness direction of the display screen.

[0053] In the traditional technology, while achieving a high screen - to - body ratio, the electronic device reduces the light received by the optical device, resulting in a poor optical effect of the optical device. Therefore, how to improve the optical effect of the optical device while achieving a high screen - to - body ratio has become an urgent problem to be solved.

[0054] In view of this, the embodiments of the present application provide a display screen 110 and an electronic device 100, which can improve the light transmittance of the area on the display screen 110 opposite to the optical device 120, increase the light received by the optical device 120, and improve the optical effect of the optical device 120.

[0055] Among them, the electronic device 100 can be a mobile phone, a tablet computer, a laptop computer, an ultra - mobile personal computer (UMPC), a handheld computer, a walkie - talkie, a netbook, a point - of - sales (POS) machine, a personal digital assistant (PDA), a wearable device, a virtual reality device, a television, and other devices equipped with the display screen 110.

[0056] In the embodiments of the present application, taking the electronic device 100 as a mobile phone as an example for illustration, for example Figure 1 as shown, Figure 1 is a schematic structural diagram of the first electronic device provided by the embodiments of the present application.

[0057] Figure 2 For Figure 1 the explosion schematic diagram of the electronic device shown.

[0058] Refer to Figure 2 As shown, the electronic device 100 includes a display screen 110, a middle frame 130, a rear shell 140, and an optical device 120. Among them, the display screen 110 is mounted on the middle frame 130, the middle frame 130 is connected to the rear shell 140, and the middle frame 130, the rear shell 140, and the display screen 110 form a cavity for accommodating devices such as the optical device 120, the battery 160, and the main board 170. Along the thickness direction Z of the display screen 110, the display screen 110 has a display side for displaying images and a non-display side opposite to the display side. When the display screen 110 is connected to the rear shell 140 through the middle frame 130, the rear shell 140 is located on the non-display side of the display screen 110.

[0059] The display screen 110 can be a flexible display screen or a rigid display screen. Among them, the flexible display screen can be an OLED flexible display screen or a quantum dot light emitting diode (QLED) flexible display screen. In the embodiments of the present application, the display screen 110 is taken as an example of an OLED flexible display screen for illustration, and the setting methods of other forms of the display screen 110 are similar.

[0060] Continue to refer to Figure 1 As shown, the display screen 110 includes a display area AA and a border area NA. Among them, the display area AA is the area of the display screen 110 for performing picture display. The border area NA surrounds the display area AA, that is, the border area NA can be understood as the edge area surrounding the display area AA.

[0061] Refer to Figure 1 As shown, the border area NA can include a light-transmitting area 11 and a peripheral area 12, and the orthographic projections of the light-transmitting area 11 and the peripheral area 12 on the reference plane do not overlap. The reference plane is the plane where the length direction X and the width direction Y of the display screen 110 are located. For example Figure 1 As shown, the orthographic projection of the light-transmitting area 11 on the reference plane is circular and is located inside the orthographic projection of the peripheral area 12 on the reference plane and does not overlap with the orthographic projection of the peripheral area 12 on the reference plane, so that the peripheral area 12 surrounds the light-transmitting area 11. It should be noted that the shape of the orthographic projection of the light-transmitting area 11 on the reference plane can also be other shapes besides being circular.

[0062] Among them, the light-transmitting area 11 can also be called an optical hole area or a light-transmitting area, etc., and the peripheral area 12 can also be called a non-optical hole area or an opaque area, etc. In addition, the light-transmitting area 11 can be determined according to the field of view angle F0V of the optical device 120 (such as Figure 3 shown).

[0063] It should be noted that, in addition to being located inside the border area NA, in some embodiments, the light-transmitting area 11 may also be located inside the display area AA. At this time, the display area AA may include the light-transmitting area 11 and the pixel area. The orthographic projections of the light-transmitting area 11 and the pixel area on the reference plane do not overlap. The optical device 120 is disposed opposite to the light-transmitting area 11 along the thickness direction Z of the display screen 110, and the pixel area is used to display an image.

[0064] The optical device 120 is disposed inside the electronic device 100 and on the non-display side of the display screen 110. The optical device 120 is opposite to the light-transmitting area 11 along the thickness direction of the display screen 110. The optical device 120 emits light to the outside of the electronic device 100 or receives light from the outside of the electronic device 100 through the light-transmitting area 11.

[0065] Each optical device 120 corresponds to one light-transmitting area 11. Wherein, when the number of optical devices 120 is multiple, the number of light-transmitting areas 11 is also multiple. At this time, the multiple light-transmitting areas 11 and the multiple optical devices 120 are in one-to-one correspondence, and each light-transmitting area 11 is opposite to the corresponding optical device 120 along the thickness direction Z of the display screen 110.

[0066] The number of optical devices 120 may be one or more. In addition, the optical device 120 may be a camera, a color temperature sensor, an ambient light sensor, an indicator light, an infrared lamp, or an infrared camera, etc.

[0067] The structure of the display screen 100 provided in the embodiments of the present application will be described in detail below with reference to specific embodiments.

[0068] Embodiment 1

[0069] Figure 3 For Figure 1 a schematic cross-sectional view of the electronic device shown.

[0070] See Figure 3 As shown, the electronic device includes a display screen 110, an optical device 120, a flexible member 180, and a structural member 190. Among them, the optical device 120 is connected to the structural member 190 and is spaced apart from the display screen 110. The optical device 120 is opposite to the light-transmitting area 11. The flexible member 180 is disposed between the display screen 110 and the structural member 190 and abuts against the structural member 190 and the display screen 110 respectively. The flexible member 180 is used to prevent the structural member 190 from damaging the display screen 110. The flexible member 180 is made of a flexible material. For example, it can be made of foam. At this time, the flexible member 180 can also be called a foam member.

[0071] The structural member 90 has a receiving portion for receiving the optical device 120, reducing the thickness of the optical device 120 and the structural member 190. The structural member 190 is used to connect with the middle frame 130 to fix the optical device 120. The specific structure of the structural member 190 is not limited here. For example, the structural member 190 can be a plate-like structure, and the receiving portion is a groove.

[0072] Continuing to refer to Figure 3 As shown, the display screen 110 may include a cover plate 10, an optical adhesive layer 20, a display panel 30, a back film layer 40, and a substrate 50. Among them, the cover plate 10, the optical adhesive layer 20, the display panel 30, the back film layer 40, and the substrate 50 are arranged along the thickness direction Z of the display screen 110. That is to say, the cover plate 10, the optical adhesive layer 20, the display panel 30, the back film layer 40, and the substrate 50 are stacked along the thickness direction Z of the display screen 110.

[0073] Refer to Figure 3 As shown, the orthographic projection of the display panel 30 on the reference plane is a complete planar structure. That is to say, there is no through hole penetrating the display panel 30, which improves the reliability of the area of the display screen 100 opposite to the optical device 120 and reduces the risk of black spots in this area.

[0074] To improve the optical effect of the optical device 120, refer to Figure 3 As shown, the display screen 110 may further include a first through hole 101. The first through hole 101 penetrates the back film layer 40 and the substrate 50 along the thickness direction Z of the display screen 110. At this time, a part of the first through hole 101 is disposed in the back film layer 40 and another part is disposed in the substrate 50. The optical device 120 is opposite to the first through hole 101 along the thickness direction of the display screen 110, and the optical device 120 receives light through the first through hole 101. The light transmittance at the first through hole 101 is high, so that the light received by the optical device 120 increases, thereby improving the light transmittance of the area of the display screen 100 opposite to the optical device 120 and achieving the purpose of improving the optical effect of the optical device 120.

[0075] Among them, the specific shape of the first through hole 101 is not limited here. Exemplarily, the first through hole 101 can be a circular through hole.

[0076] Exemplarily, refer to Figure 3As shown, the orthographic projection of the first through hole 101 on the reference plane may be located inside the orthographic projection of the optical device 120 on the reference plane. However, in some embodiments, a part of the orthographic projection of the first through hole 101 on the reference plane may also be located inside the orthographic projection of the optical device 120 on the reference plane, and another part may be located outside the orthographic projection of the optical device 120 on the reference plane. Therefore, the first through hole 101 and the optical device 120 may partially overlap or completely overlap in the thickness direction of the display screen 100.

[0077] See Figure 3 As shown, the light-transmitting region 11 is opposite to the first through hole 101 in the thickness direction of the display screen 110. It can be seen that the light transmitted through the light-transmitting region 11 can be received by the optical device 120 through the first through hole 101. That is to say, the optical device 120 receives the light passing through the light-transmitting region 11 through the first through hole 101.

[0078] In one implementation, see Figure 3 As shown, the orthographic projection of the first through hole 101 on the reference plane is located inside the orthographic projection of the light-transmitting region 11 on the reference plane. That is to say, the first through hole 101 is located inside the light-transmitting region 11. In another implementation, a part of the orthographic projection of the first through hole 101 on the reference plane is located inside the orthographic projection of the light-transmitting region 11 on the reference plane, and another part of the orthographic projection of the first through hole 101 on the reference plane is located outside the orthographic projection of the light-transmitting region 11 on the reference plane. That is to say, a part of the first through hole 101 is located inside the light-transmitting region 11. Therefore, the first through hole 101 may be partially or completely located inside the light-transmitting region 11.

[0079] Figure 4 The figure is a schematic diagram of a display panel 30 provided by an embodiment of the present application from a top-down perspective. Figure 5 is Figure 4 a cross-sectional schematic diagram in the A-A direction in

[0080] In order to further improve the optical effect of the optical device 120, in some possible implementation manners, see Figure 5 As shown, the display panel 30 may further include a first part 31 and a second part 32. Among them, the thickness of the first part 31 in the thickness direction Z of the display screen 110 is less than the thickness of the second part 32 in the thickness direction Z of the display screen 110. As Figure 3 shown, the first part 31 is opposite to the first through hole 101 in the thickness direction Z of the display screen 110, so that the first part 31 and the light-transmitting region 11 are opposite in the thickness direction of the display screen 110.

[0081] The thickness of the first part 31 is less than that of the second part 32, which means that the display panel 30 has different structures in the first part 31 and the second part 32. For example, in the first part 31 of the display panel 30, the layer structure formed by inorganic materials is removed, while in the second part 32 of the display panel 30, the layer structure formed by inorganic materials is retained. Therefore, by removing part or all of the layer structure formed by inorganic materials in the first part 31 and increasing the light transmittance of the first part 31 to light, the light transmittance of the light-transmitting region 11 to light can be further improved.

[0082] At least part of the orthographic projection of the first part 31 on the reference plane is located inside the orthographic projection of the first through hole 101 on the reference plane, ensuring that the light passing through the first part 31 enters the first through hole 101, and the optical device 120 receives the light passing through the first part 31 through the first through hole 101.

[0083] In one embodiment, a part of the orthographic projection of the first part 31 on the reference plane may be located inside the orthographic projection of the first through hole 101 on the reference plane, and another part may be located outside the orthographic projection of the first through hole 101 on the reference plane. For example, the orthographic projections of the first part 31 and the first through hole 101 on the reference plane may both be circular, and the diameter of the circle corresponding to the first part 31 is greater than the diameter of the circle corresponding to the first through hole 101, so that the first part 31 covers the first through hole 101. In another embodiment, the orthographic projection of the first part 31 on the reference plane may also be located inside the orthographic projection of the first through hole 101 on the reference plane. For example, the orthographic projections of the first part 31 and the second through hole 101 on the reference plane may both be circular, and the diameter of the circle corresponding to the first part 31 may be equal to or less than the diameter of the circle corresponding to the first through hole 101, so that the first part 31 covers part of the first through hole 101.

[0084] In one embodiment, referring to Figure 3 As shown, the orthographic projection of the first part 31 on the reference plane is located inside the orthographic projection of the light-transmitting region 11 on the reference plane, that is to say, the first part 31 is located inside the light-transmitting region 11. In another embodiment, a part of the orthographic projection of the first part 31 on the reference plane is located inside the orthographic projection of the light-transmitting region 11 on the reference plane, and another part of the orthographic projection of the first part 31 on the reference plane is located outside the orthographic projection of the light-transmitting region 11 on the reference plane, that is to say, a part of the first part 31 is located inside the light-transmitting region 11. Therefore, the first part 31 may be partially or entirely located inside the light-transmitting region 11.

[0085] Referring to Figure 4As shown, the display panel 30 may include a display area 33 and a border area 34. Among them, the display area 33 forms a display region AA and is used to display images. The border area 34 can be understood as the area of the display panel 30 other than the display area 33, and the border area 34 is located inside the frame area NA.

[0086] Continue to refer to Figure 4 As shown, the border area 34 may include a first area 341 formed by a first portion 31 and a second area 342 formed by a part of a second portion 32. Among them, the orthographic projections of the first area 341 and the second area 342 on the reference plane do not overlap. The first area 341 is opposite to the first through hole 101 along the thickness direction Z of the display screen 110, and the second area 342 is opposite to the peripheral area 12 along the thickness direction of the display screen 110.

[0087] Exemplarily, the display panel 30 may include an inorganic layer (not shown in the figure), an organic layer (not shown in the figure), and metal traces (not shown in the figure). The inorganic layer refers to a layer structure formed by inorganic materials, and the number of inorganic layers may be multiple, and the multiple inorganic layers are arranged along the thickness direction Z of the display screen 110. Of course, in some embodiments, the number of inorganic layers may also be one. The organic layer refers to a layer structure formed by organic materials, and the organic layer may be a multi-layer structure, that is, the number of organic layers may be multiple, and the multiple organic layers are arranged along the thickness direction Z of the display screen 110. Of course, in some embodiments, the number of organic layers may also be one.

[0088] Regarding the arrangement of the organic layer and the inorganic layer, there is no limitation here. For example, a part of the inorganic layer and a part of the organic layer are alternately arranged along the thickness direction Z of the display screen 110.

[0089] The number of metal traces may be one or more. In addition, there is no limitation on how to arrange the metal traces. For example, the metal traces may be disposed on the inorganic layer and / or the organic layer, or the metal traces may also be located between the inorganic layer and the organic layer.

[0090] In one implementation, the first portion 31 may include an organic layer, that is, there are no inorganic layers and metal traces inside the first portion 31. In another implementation, the first portion 31 may also include an organic layer and an inorganic layer. At this time, the first portion 31 includes a part of the inorganic layer in the display panel 30. It can be seen that the first portion 31 can remove some or all of the inorganic layers.

[0091] Since the first portion 31 removes some or all of the inorganic layers, the thickness of the first portion 31 in the thickness direction Z of the display screen 110 is reduced, and the light transmittance of the first portion 31 is increased, thereby increasing the light received by the optical device 120.

[0092] The second part 32 includes an inorganic layer, an organic layer, and metal traces. That is to say, the second part 32 is composed of three parts: an inorganic layer, an organic layer, and metal traces.

[0093] In one implementation, the organic layers in the first part 31 and the second part 32 can be an integral structure. In another implementation, when the first part 31 has an inorganic layer and an organic layer, the inorganic layer of the first part 31 and a part of the inorganic layer of the second part 32 are an integral structure.

[0094] In some possible implementation manners, referring to Figure 3 as shown, the display screen 110 may further include a polarizer 60. The polarizer 60 is disposed between the optical adhesive layer 20 and the display panel 30. The polarizer 60 is respectively connected to the optical adhesive layer 20 and the display panel 30. The positive projections of the light-transmitting region 11, the first through hole 101, and the first part 31 on the reference plane are all located inside the positive projection of the polarizer 60 on the reference plane. That is to say, the polarizer 60 covers the first through hole 101 and the first part 31 along the thickness direction Z of the display screen 110, or a part of the polarizer 60 is located inside the light-transmitting region 11. In this way, by disposing the polarizer 60 inside the display screen 110, the reflected light can be eliminated, and further, the display effect of the display screen 110 can be improved.

[0095] In some possible implementation manners, continue to refer to Figure 3 as shown, the display screen 110 may further include an opaque first ink layer 70. The first ink layer 70 is located between the cover plate 10 and the optical adhesive layer 20 and is respectively connected to the cover plate 10 and the optical adhesive layer 20. The first ink layer 70 is located inside the border area NA. At least a part of the first ink layer 70 does not overlap with the positive projection of the first through hole 101 on the reference plane. For example, the first ink layer 70 does not overlap with the positive projection of the first through hole 101 on the reference plane.

[0096] The first ink layer 70 is located inside the peripheral area 12. The first ink layer 70 avoids the light-transmitting region 11, allowing light to pass through while blocking the devices inside the peripheral area 12 and under the cover plate 10, improving the aesthetics of the display screen 110.

[0097] It should be noted that the optical adhesive layer 20 contacts the cover plate 10 through the area where the first ink layer 70 avoids the first through hole 101.

[0098] In some possible implementation manners, continue to refer to Figure 3As shown, the display screen 110 may further include a surface layer 90. The surface layer 90 is disposed on the side of the cover plate 10 facing away from the optical adhesive layer 20 along the thickness direction Z of the display screen 110. The surface layer 90 covers the first through hole 101 and the first portion 31 along the thickness direction Z of the display screen 110, so that the orthographic projection of the light-transmitting region 11 on the reference plane is located inside the orthographic projection of the surface layer 90 on the reference plane.

[0099] In this way, by providing the surface layer 90 on the surface of the cover plate 10, the anti-extrusion and impact resistance of the area on the display screen 110 opposite to the first through hole 101 can be further improved, and the anti-extrusion and impact resistance of this area can be enhanced.

[0100] It should be noted that the display screen 100 provided in this embodiment may or may not adopt the display panel 30 composed of the first portion 31 and the second portion 32, and the first portion 31 removes part or all of the inorganic layer. Similarly, the display screen 100 may also remove the surface layer 90 and / or the polarizer 60. Further, the display screen 100 may further include a second through hole 102 penetrating the polarizer 60.

[0101] Embodiment 2

[0102] Figure 6 This is a schematic cross-sectional view of the second electronic device provided in the embodiment of the present application.

[0103] Figure 6 Different from Figure 3 that, the display screen 110 may further include a light-transmitting second ink layer 80. The second ink layer 80 is located inside the light-transmitting region 11, between the cover plate 10 and the optical adhesive layer 20, and the second ink layer 80 is provided in the same layer as the first ink layer 70. The second ink layer 80 can block the optical device 120 exposed through the first through hole 101, which helps to further improve the aesthetics of the display screen 110. At the same time, the second ink layer 80 has light-transmitting characteristics, which can meet the usage requirements of the optical device 120.

[0104] It should be noted that the surface layer 90 of the display screen 100 in this embodiment can also be removed. In addition, the display screen 100 may or may not adopt the display panel 30 composed of the first portion 31 and the second portion 32, and the first portion removes part or all of the inorganic layer. In addition, the polarizer 60 of the display screen 100 can also be removed, or the display screen 100 can be provided with a polarizer 60 having a first through hole 102.

[0105] Embodiment 3

[0106] Figure 7 This is a schematic cross-sectional view of the third electronic device provided in the embodiment of the present application.

[0107] Figure 7 Different fromFigure 6 The difference is that the surface layer 90 is removed from the display screen 110, which can reduce the frame width of the electronic device 100.

[0108] Specifically, when the display screen 110 has the surface layer 90, as Figure 6 shown, K1 = L + M + D, where K1 is the distance between the boundary line of the display area AA and the frame 150, L is the distance between the boundary line of the display area AA and the boundary line of the light-transmitting area 11, M is the distance between the edge of the surface layer 90 and the boundary line of the light-transmitting area 11, and D is the distance between the surface layer 90 and the frame 150 of the electronic device 100. Among them, in some embodiments, the frame 150 can also be referred to as the small A shell.

[0109] However, when the surface layer 90 is removed from the display screen 110, as Figure 7 shown, K2 = L + B, where K2 is the distance between the boundary line of the display area AA and the frame 150, L is the distance between the boundary line of the display area AA and the boundary line of the light-transmitting area 11, and B is the distance between the edge of the light-transmitting area 11 and the frame 150 of the electronic device 100.

[0110] Since M + D > B, K2 is less than K1. Therefore, after removing the surface layer 90, the frame width of the electronic device 100 can be reduced.

[0111] It should be noted that the second ink layer 80 and / or the polarizer 60 can also be removed from the display screen 100 of this embodiment. Alternatively, the polarizer 60 with the second through hole 102 can be used for the display screen 100. In addition, the display screen 100 can also use or not use the display panel 30 composed of the first part 31 and the second part 32, and part or all of the inorganic layer is removed from the first part 31.

[0112] Embodiment 4

[0113] Figure 8 This is a schematic cross-sectional view of the fourth electronic device provided by the embodiments of the present application.

[0114] Figure 8 Different from Figure 7 that, the display screen 110 can further include a second through hole 102. The second through hole 102 penetrates the polarizer 60 along the thickness direction Z of the display screen 110. The second through hole 102 is opposite to the first through hole 101 along the thickness direction Z of the display screen 110, and the second through hole 102 is opposite to the optical device 120. The optical device 120 receives the light passing through the second through hole 102 through the first through hole 101. In this way, the light transmittance of the light-transmitting area 11 to light can be further improved, which helps to further improve the optical effect of the optical device 120.

[0115] The orthographic projection of the second through-hole 102 on the reference plane may be located inside the orthographic projection of the light-transmitting region 11 on the reference plane. For example, the orthographic projection of the second through-hole 102 on the reference plane may be circular, the orthographic projection of the light-transmitting region 11 on the reference plane may be circular, and the diameter of the circle corresponding to the second through-hole 102 is smaller than that of the circle corresponding to the light-transmitting region 11. Alternatively, a part of the orthographic projection of the second through-hole 102 on the reference plane may be located inside the orthographic projection of the light-transmitting region 11 on the reference plane. For example, the orthographic projection of the second through-hole 102 on the reference plane may be circular, the orthographic projection of the light-transmitting region 11 on the reference plane may be circular, and the diameter of the circle corresponding to the second through-hole 102 is larger than that of the circle corresponding to the light-transmitting region 11.

[0116] Wherein, the specific shape of the second through-hole 102 is not limited herein. Exemplarily, the second through-hole 102 may be a circular through-hole.

[0117] Exemplarily, referring to Figure 8 As shown, the inner diameter of the first through-hole 101 is the same as that of the second through-hole 102, and the axis of the first through-hole 101 coincides with the axis of the second through-hole 102. Alternatively, in some embodiments, the inner diameter of the first through-hole 101 may also be smaller than that of the second through-hole 102. In this case, the axis of the first through-hole 101 and the axis of the second through-hole 102 may coincide or be arranged at intervals. In other embodiments, the inner diameter of the first through-hole 101 may also be larger than that of the second through-hole 102. In this case, the axis of the first through-hole 101 and the axis of the second through-hole 102 may coincide or be arranged at intervals.

[0118] In some embodiments, the display screen 110 may further include a filling member (not shown in the figure). The filling member is disposed inside the second through-hole 102 and is made of a transparent material. By absorbing the height difference between the cover plate 10 and the optical adhesive layer 20 through the filling member, the reliability of the light-transmitting region 11 can be further improved.

[0119] It should be noted that the second ink layer 80 of the display screen 100 provided in this embodiment may also be removed. In addition, the display screen 100 may or may not adopt the display panel 30 composed of the first part 31 and the second part 32, and part or all of the inorganic layer is removed from the first part 31. In addition, the display screen 100 may further be provided with a surface layer 90 on the surface of the cover plate 10 away from the display panel 30.

[0120] Embodiment Five

[0121] Figure 9 It is a schematic cross-sectional view of the fifth electronic device provided by the embodiment of the present application.

[0122] Figure 9 With Figure 7The difference is that the polarizer 60 is removed from the display screen 110. At this time, the optical adhesive layer 20 is connected to the display panel 30. In this way, by removing the entire polarizer 60, the light transmittance of the area on the display screen 110 opposite to the first through hole 101 can be further improved, and the optical effect of the optical device 120 can be further improved.

[0123] It should be noted that the second ink layer 80 can also be removed from the display screen 100 provided in this embodiment. In addition, the display panel 30 composed of the first part 31 and the second part 32 can be used or not used for the display screen 100, and part or all of the inorganic layer is removed from the first part 31. In addition, the display screen 100 can also be provided with a surface layer 90 on the surface of the cover plate 10 away from the display panel 30.

[0124] In summary, there are the following several solutions to improve the light transmittance of the light-transmitting area 11:

[0125] The first solution is to set the first through hole 101. The second solution is to set the first through hole 101 and use the display panel 30 composed of the first part 31 and the second part 32 with different thicknesses. At this time, part or all of the inorganic layer is removed from the first part 31. The third solution is to remove the surface layer 90. The fourth solution is to remove the polarizer 60. The fifth solution is to remove the polarizer 60 in the light-transmitting area 11, that is, to set the second through hole 102 penetrating the polarizer 60. The sixth solution is to remove the second ink layer 80.

[0126] In order to improve the optical effect of the optical device 120, the display screen 110 provided in this application can select the first solution, or the display screen 100 can also add at least one of the second solution to the sixth solution on the basis of adopting the first solution.

[0127] In addition, when the surface layer 90 is removed, not only can the light transmittance of the light-transmitting area 11 be improved, but also the frame width of the electronic device 100 can be reduced. Of course, when the surface layer 90 exists, the anti-extrusion and impact resistance of the light-transmitting area 11 can be improved.
