Abstract
Description
Technical Field
[0001] This application relates to the field of electronic product technology, and in particular to a display screen assembly and electronic device. Background Technology
[0002] With the development of electronic products, electronic devices have become increasingly popular. The stacking structure of displays is quite unique, using flexible polyethylene terephthalate (PET) and ultra-thin glass (UTG) materials for the surface-stacked films. For example, foldable screen devices constantly unfold and fold, requiring a more flexible stacking structure. Because a black ink layer exists between the PET layer and the optically clear adhesive (OCA) layer, a step difference is created. This results in a significant indentation of the flexible PET at the front-facing camera's aperture. This indentation forms an equivalent negative lens, introducing additional optical power to the camera and severely affecting the peroxide value (PV) of the front-facing camera's aperture, leading to poor image quality. Summary of the Invention
[0003] This application provides a display assembly and an electronic device to solve the problem of poor photo quality from a camera.
[0004] In a first aspect, embodiments of this application provide a display assembly for use in an electronic device. The electronic device includes a front-facing camera and comprises a protective film, a first optical adhesive layer, a glass sheet, a polarizer, a second optical adhesive layer, and a panel screen, which are sequentially stacked.
[0005] The glass sheet, polarizer, second optical adhesive layer, and panel screen are provided with camera holes corresponding to the positions of the front-facing camera;
[0006] The protective film has a black ink layer on the surface facing the first optical adhesive layer. The black ink layer has a light-transmitting hole at the position corresponding to the camera hole. The protective film has a light-transmitting hole at the position corresponding to the light-transmitting hole. The protective film has a first charged body at the position corresponding to the light-transmitting hole.
[0007] A second charged body is provided on the glass plate at the position corresponding to the light-transmitting hole. The second charged body is insulated from the first charged body, and the first charged body and the second charged body have the same charge.
[0008] Secondly, embodiments of this application also provide an electronic device, including: a front-facing camera and the display assembly described in the first aspect.
[0009] In this embodiment, a first charged body is disposed at the position corresponding to the light-transmitting hole on the protective film; a second charged body is disposed on the glass sheet at the position corresponding to the light-transmitting hole. The second charged body is insulated from the first charged body, and the first and second charged bodies have the same charge. Thus, when the protective film is concave, the distance between the protective film and the glass sheet surface decreases, increasing the repulsive force between the first and second charged bodies, thereby preventing concavity and solving the problem of concavity deformation of the protective film at the camera aperture of the front-facing camera, improving the PV value of the front-facing camera aperture. Therefore, this embodiment improves the camera's image capture effect.

[0020] See Figure 1 and Figure 2 This application provides a display assembly for use in an electronic device, which includes a front-facing camera. As shown in the figure, the display assembly includes a protective film 10, a first optical adhesive layer 11, a glass sheet 12, a polarizer 13, a second optical adhesive layer 14, and a panel screen 15, which are sequentially stacked.
[0021] The glass sheet 12, polarizer 13, second optical adhesive layer 14 and panel screen 15 are provided with camera holes 16 corresponding to the positions of the front-facing camera;
[0022] The protective film 10 has a black ink layer 101 on the surface facing the first optical adhesive layer 11. The black ink layer 101 has a light-transmitting hole 1011 at the position corresponding to the camera hole 16. The protective film 10 has a first charged body 102 at the position corresponding to the light-transmitting hole 1011.
[0023] A second charged body 121 is provided on the glass plate 12 at the position corresponding to the camera hole 16. The second charged body 121 is insulated from the first charged body 102, and the first charged body 102 and the second charged body 121 have the same charge.
[0024] In this embodiment, since the first charged body 102 and the second charged body 121 have the same charge, the first charged body 102 and the second charged body 121 generate a repulsive force.
[0025] Optionally, the protective film can be a PET film, and the glass sheet 12 can be ultra-thin glass.
[0026] It should be noted that, typically, a solid optical adhesive 17 and a steel plate 18 are also provided on the side of the panel screen 15 away from the glass sheet 12. The solid optical adhesive 17 is located between the steel plate 18 and the panel screen 15, and the panel screen 15 is supported by the steel plate 18.
[0027] In this embodiment, a first charged body 102 is provided on the protective film 10 at the position corresponding to the light-transmitting hole 1011; a second charged body 121 is provided on the glass sheet 12 at the position corresponding to the light-transmitting hole 1011. The second charged body 121 is insulated from the first charged body 102, and the first charged body 102 and the second charged body 121 have the same charge. Thus, when the protective film 10 is concave, the distance between the protective film 10 and the surface of the glass sheet 12 decreases, and the repulsive force between the first charged body 102 and the second charged body 121 increases, thereby preventing the concavity from occurring. This solves the problem of concavity deformation of the protective film 10 at the camera hole 16 of the front-facing camera, improving the PV value of the camera hole. Therefore, in this embodiment, the camera's image capture effect is improved.
[0028] Optionally, in some embodiments, the protective film 10 has a protrusion 103 extending into the light-transmitting hole 1011 at the position corresponding to the light-transmitting hole 1011. The protrusion 103 is bonded to the first optical adhesive layer 11, and the first charged body 102 is disposed on the side of the protrusion 103 facing the glass sheet 12.
[0029] In this embodiment, the protective film 10 and the first optical adhesive layer 11 can be patterned. The protective film 10 is thickened at the camera hole 16 of the front camera, forming the aforementioned protrusion 103. This improves the rigidity of the protective film at the light-transmitting hole 1011 of the black ink layer 101, thereby reducing the degree of concavity of the protective film at the camera hole 16 of the front camera, and thus improving the PV value of the camera hole of the front camera.
[0030] Optionally, the protrusion 103 matches the light-transmitting hole 1011, and the shape of the light-transmitting hole 1011 can be set according to actual conditions. For example, in some embodiments, the light-transmitting hole 1011 is circular. Optionally, the protrusion 103 may be partially or entirely located within the light-transmitting hole 1011, and the shape of the protrusion 103 corresponds to the shape of the light-transmitting hole 1011. For example, in some embodiments, the protrusion 103 is cylindrical.
[0031] Optionally, in some embodiments, the protrusion 103 protrudes axially from the light-transmitting hole 1011 at a height equal to the axial depth of the light-transmitting hole 1011.
[0032] In this embodiment, since the height of the protrusion 103 protruding axially from the light-transmitting hole 1011 is the same as the depth of the light-transmitting hole 1011 in the axial direction, the black ink layer 101 facing the glass sheet 12 has a planar structure. This eliminates the need for the OCA to fill the ink gap at the location of the light-transmitting hole 1011.
[0033] It should be noted that the height of the protrusion 103 protruding axially from the light-transmitting hole 1011 can be set according to actual needs. For example, in some embodiments, the height of the protrusion 103 protruding axially from the light-transmitting hole 1011 ranges from 14μm to 16μm. Optionally, the height of the portion of the protective film 10 without the protrusion 103 can be approximately 65μm.
[0034] It should be understood that the height of the aforementioned protective film 10 can be understood as the thickness of the protective film 10.
[0035] Optionally, in some embodiments, the dimensions of the cross-section of the protrusion 103 in the radial direction of the light-transmitting hole 1011 are the same as the dimensions of the radial cross-section of the light-transmitting hole 1011.
[0036] In this embodiment, the protrusion 103 is completely consistent with the light-transmitting hole 1011. The protrusion 103 is used to fill the light-transmitting hole 1011. At this time, the OCA layer is made into a pit pattern to match the shape of the protective film. Therefore, the problem of using OCA to fill the ink step difference is solved.
[0037] Optionally, in some embodiments, the second charged body 121 is disposed on the side of the glass sheet 12 facing the first optical adhesive layer 11.
[0038] In this embodiment, since the second charged body 121 is disposed on the side of the glass sheet 12 facing the first optical adhesive layer 11, the second charged body 121 and the first charged body 102 have a small gap, and thus, when the protective film 10 has a depression, the second charged body 121 and the first charged body 102 can generate a large repulsive force.
[0039] Optionally, in some embodiments, the second charged body 121 described above may also be disposed in other locations, such as on the side of the glass sheet 12 facing away from the protective film 10.
[0040] Optionally, the first charged body 102 and the second charged body 121 can be understood as positively charged protons or negatively charged electrons, which do not require electricity and are thus point charges. As long as there is no contact between substances with opposite charges, the charge will not be neutralized.
[0041] Optionally, in some embodiments, the charge of the first charged body 102 is the same as the charge of the second charged body 121.
[0042] like Figure 3 As shown, the forces acting on the first charged body 102 and the second charged body 121 are analyzed. The first charged body 102 and the second charged body 121 are in equilibrium under the four forces F1, F2, F3 and F4, and their charges are equal. This ensures that each position of the first charged body 102 is in a state of force equilibrium. If the PET has a dent, the repulsive force F4 between the first charged body 102 and the second charged body 121 will increase as the distance decreases (the smaller the distance, the greater the repulsive force), thereby preventing the dent from forming and improving the shooting effect.
[0043] like Figure 2 As shown, the X-axis includes two forces, F5 and F6. F5 is the squeezing force of the right black ink layer on the first charged body 102 or the second charged body 121, and F6 is the squeezing force of the left black ink layer on the first charged body 102 or the second charged body 121.
[0044] The Y-axis includes four forces: F1, F2, F3, and F4, where F1 = F3 and F2 = F4. F1 is the supporting force on the first charged body 102 or the second charged body 121, F2 is the weight of the first charged body 102 or the second charged body 121, and F3 and F4 are both Coulomb forces, where F3 = F4 = k*(Q1Q2 / R). 2 ), where k represents the electrostatic constant, Q1 represents the charge of the first charged body 102, Q2 represents the charge of the second charged body 121, and Q1 = Q2, and R is the distance between the first charged body 102 or the second charged body 121.
[0045] Optionally, in some embodiments, the first optical adhesive layer 11 can be formed by coating an insulating optical adhesive.
[0046] In this embodiment, since the first optical adhesive layer 11 is formed by using insulating optical adhesive, the first charged body 102 and the second charged body 121 are in a relatively insulating environment, without the need for external insulation protection. The first charged body 102 and the second charged body 121 will not react with objects in direct contact, are in a stable state, and will not have their charge neutralized by other charged substances.
[0047] Optionally, in some embodiments, the first charged body 102 is coated on a first region of the surface of the protrusion 103, and the second charged body 121 is coated on a second region of the surface of the glass sheet, the first region and the second region are disposed opposite to each other, and the size of the first region is the same as the size of the second region.
[0048] Optionally, in some embodiments, the black ink layer 101 is a black ring-shaped ink.
[0049] like Figure 2 As shown, the black ink layer 101 has a light-transmitting hole 1011 in the middle, which is a circular hole and is directly opposite the camera hole.
[0050] This application also provides an electronic device, which includes a front-facing camera and a display screen assembly.
