[0018] It is to be understood that the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the present disclosure. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The accompanying drawings, which are incorporated in and constitute a part of this specification, illustrate embodiments consistent with the present disclosure and, together with the description, serve to explain the principles of the present disclosure.

[0027] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0028] Figure 1 This is a schematic diagram of a display screen assembly structure in the prior art. Figure 1 As shown, in some related technologies, a mobile terminal may include a cover plate 10 , a display module 20 and a camera module 30 .

[0029] The display module 20 is provided with an opening 21, and the camera module 30 extends into the opening 21. In order to prevent the camera module 30 from damaging the display module 20 due to impact during use, a certain distance needs to be set between the camera module 30 and the opening 21, which makes it difficult to further reduce the opening 21.

[0030] In order to reduce the opening 21, it is possible to consider setting the camera module 30 below the display module 20, that is, not extending the camera module 30 into the opening 21 of the display module 20. However, in actual production settings, the cover plate 100 of the terminal device is also provided with an ink screen 11, and the existence of the ink screen 11 will block the first visual field area 31 of the camera module 30. Although such a setting can prevent the camera module 30 from damaging the display module 20, it is not conducive to reducing the opening 21 of the display module 20.

[0031] In order to solve the above problems, an embodiment of the present disclosure provides a display screen assembly for terminal devices such as mobile phones and tablets. The terminal device may include a camera module 300 arranged under the display screen assembly.

[0032] Figure 2a FIG. 1 is a schematic diagram showing the structure of a display screen assembly according to an exemplary embodiment. Figure 2a As shown, the display screen assembly includes a cover plate 100 and a display module 200 disposed under the cover plate 100 .

[0033] The cover plate 100 may be a transparent glass cover plate for protecting the display module 200 , and includes a first surface 101 and a second surface 102 which are arranged opposite to each other. The second surface 102 is the lower surface of the cover plate 100 , which is located on one side inside the terminal device and arranged opposite to the display module 200 .

[0034] The cover plate 100 is provided with a diverging device 110, which is a device for diverging light in the process of external light being transmitted to the camera module 300 inside the terminal device. The diverging device 110 is arranged as a concave lens structure, and utilizes the effect of the concave lens structure to diverge light, thereby expanding the field of view area of ​​the camera module 300, that is, the first field of view area 301 of the camera module 300 can be expanded to the second field of view area 302 through the concave lens structure, thereby achieving the first field of view area 301 of the camera module 300 inside the terminal device to a certain extent while ensuring the shooting function and viewing angle of the terminal device, so the size of the opening area can be reduced.

[0035] In the disclosed embodiment, the diverging device 110 is disposed on the lower surface of the cover plate 100, that is, the second surface 102 of the cover plate 100, opposite to the display module 200. It should be noted that in other possible embodiments, the diverging device may also be disposed on the first surface 101 of the cover plate 100, as long as the purpose of expanding the first visual field area 301 can be achieved.

[0036] In the present disclosure, the diverging device 110 may be a concave lens sheet, and the concave lens sheet may be disposed on the second surface 102 of the cover plate 100. In a specific implementation, the second surface 102 of the cover plate 100 is a plane, and the concave lens sheet may be disposed on the plane. In some possible embodiments, a groove capable of accommodating the concave lens sheet may be opened on the second surface 102, and the concave lens sheet may be disposed at the groove of the second surface 102. The concave lens sheet may be a plano-concave lens structure or a bi-concave lens structure, which is determined in actual use according to the range of the second field of view area 302 to be achieved.

[0037] Based on the above technical features, the concave lens sheet can be a plano-concave lens structure, and the side of the concave lens sheet connected to the cover plate 100 is a plane, that is, the concave surface of the concave lens sheet is opposite to the display module 200 .

[0038] It should be noted that, in the present disclosure, the diverging device 110 may be a component disposed on the cover plate 100, that is, the diverging device 110 is connected to the cover plate 100 as an independent component, for example, a concave lens sheet may be disposed on the cover plate 100. The diverging device 110 may also be a part of the cover plate 100, that is, a concave lens structure is directly formed on the cover plate 100 as the diverging device 110.

[0039] For example, Figure 2a As shown, the second surface 102 of the cover plate 100 of the embodiment of the present disclosure is provided with a pit, and the portion provided with the pit is a concave lens structure, which plays the role of the diverging device 110, and can expand the first visual field area 301 to the expanded visual field area 302. By providing the pit on the second surface 102 of the cover plate 100 to achieve the role of the concave lens structure, such a setting does not require the addition of related components on the cover plate 100, which is not only conducive to controlling the thickness of the mobile device, but also conducive to maintaining a stable connection relationship between the cover plate 100 and the display module 200.

[0040] Figure 2b FIG. 1 is a schematic diagram showing the structure of a display screen assembly according to another exemplary embodiment. Figure 2b In other possible embodiments, a pit may be provided on the first surface 101 of the cover plate 100, that is, the upper surface, so as to form a concave lens structure, which can ensure that the second surface inside is flat and easy to fit.

[0041] Figure 2c is a schematic diagram of the structure of a display screen assembly according to another exemplary embodiment. Figure 3 FIG. 1 is a schematic diagram showing the structure of a display screen assembly according to another exemplary embodiment. Figure 2c , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a double concave lens structure can also be provided on the cover plate 100, that is, pits are provided on the first surface 101 and the second surface 102 of the cover plate 100 to meet a larger divergence angle. While ensuring the angle of the second field of view area 302, the first field of view area 301 can be further reduced, thereby further reducing the size of the opening.

[0042] like Figure 2a As shown, the display module 200 is disposed below the cover plate 100. An opening 201 is disposed on the display module 200 at a position opposite to the diffusion device 110.

[0043] Generally, the display module 200 may include an optical adhesive layer 202, a polarizer 203, an OLED (organic light emitting diode) flexible screen 204, and a back layer 205 from top to bottom. The OLED (organic light emitting diode) flexible screen 204 may be an AMOLED (active matrix organic light emitting diode panel) flexible screen. The display module 200 using the AMOLED flexible screen is thinner and lighter, and is increasingly valued in the application of terminal devices. However, due to the limitations of the flexible AMOLED packaging technology, the impact resistance of the edge of the opening on the display screen is very poor. If the distance between the camera and the opening is too small, the camera will hit the display screen and cause the display screen to fail. If the distance is set too large, the opening of the display screen cannot be reduced, reducing the competitiveness of the product. The setting disclosed in the present invention does not need to set the camera in the opening of the display module, which not only avoids the impact of the camera on the display screen, but also can achieve the purpose of reducing the opening on the display module.

[0044] In the present disclosure, the width of the opening 201 on the display module 200 is consistent with the width of the concave lens structure of the diverging device 110, so that the size of the opening 201 of the display module 200 can be minimized, the display range of the terminal device can be further increased, and the competitiveness of the product can be improved.

[0045] On the basis of the above technical features, the opening 201 of the display module 200 can be set to be cylindrical, and the diverging device 110 is disc-shaped, then the diameter of the opening 201 of the display module 200 is consistent with the diameter of the diverging device 110. Setting the opening 201 to be cylindrical is more conducive to meeting the shooting function requirements of the terminal device, and setting the diverging device 110 to be disc-shaped can maximize the expansion of the first field of view area 301.

[0046] The width of the opening 201 on the display module 200 is set to be consistent with the width of the concave lens structure of the diverging device 110, and the diameter of the opening 201 on the display module 200 is set to be consistent with the diameter of the diverging device 110, that is, the projection of the diverging device 110 perpendicular to the display module 200 can just cover the opening 201 of the display module 200 and can just accommodate the first field of view area 301. Such a setting can set the opening 201 on the display module 200 to the minimum on the basis of ensuring that the first field of view area 301 can meet the shooting requirements of the terminal device, that is, expand the display range of the terminal device.

[0047] In the above embodiment, the camera module 300 of the terminal device is disposed below the display module 200 and is disposed opposite to the opening 201 of the display module 200 .

[0048] In the present disclosure, the camera module 300 is disposed below the display module 200 , thereby avoiding possible collisions during use of the terminal device, thereby preventing the camera module 300 from damaging the display module 200 .

[0049] In the present disclosure, the width of the projection of the first field of view 301 of the camera module 300 on the second surface 102 of the cover plate 100 is the same as the width of the concave lens structure of the diverging device 110. That is, the first field of view 301 of the camera module 300 can be fully diverged and expanded by the concave lens structure of the diverging device 110, and such a setting can expand the first field of view 301 to the greatest extent.

[0050] In the present disclosure, the positions of the cover plate 100, the diverging device 110, the opening 201 of the display module 200 and the camera module 300 are arranged so that external light can enter the camera module 300 through the cover plate 100, the diverging device 110, the opening 201 of the display module 200 in sequence, thereby completing the camera function of the terminal device.

[0051] Through any of the above embodiments, the divergence device 110 of the cover plate 100 is set to expand the first field of view area 301 of the display screen assembly 300 to the second field of view area 302. Under the condition of ensuring the camera function required by the terminal device, the display screen assembly 300 is set below the display module 200 instead of extending into the opening 201 of the display module 200, thereby achieving the purpose of reducing the opening 201 of the display module 200, so that the display range of the terminal device is further increased, the competitiveness of the product is improved, and the field of view of the camera module 300 is larger, achieving a better shooting effect. At the same time, because the camera module 300 is set below the display module 200 instead of extending into the opening 201 of the display module 200, the damage that the camera module 300 may cause to the display module 200 during the use of the terminal device is avoided, and the quality of the terminal device is guaranteed.

[0052] Figure 2c FIG. 1 is a schematic diagram showing the structure of a display screen assembly according to another exemplary embodiment. Figure 2c As shown, in some embodiments, a convex lens sheet 210 can be further provided at the opening 201. The convex lens sheet 210 has a focusing effect. By utilizing the focusing effect of the convex lens sheet 210, the light entering from the diverging device 110 can be gathered, so that the light path is more concentrated, and the space required for the incoming light to propagate to the camera module 300 is reduced, thereby achieving the effect of further reducing the first field of view area 301 and thus reducing the opening area.

[0053] Figure 4 is a schematic diagram of the structure of a display screen assembly according to another exemplary embodiment. Figure 5FIG. 1 is a schematic diagram showing the structure of a display screen assembly according to another exemplary embodiment. Figure 3 , Figure 4 and Figure 5 As shown, a light collecting device 206 may be provided on the display module 200 at a position corresponding to the diverging device 110, so that external light can sequentially pass through the diverging device 110 and the light collecting device 206 to enter the camera module 300 for imaging. The light collecting device 206 may be provided as a convex lens structure.

[0054] When external light passes through the display module 200, the outermost light may be affected and produce a certain degree of blurred image and cause a loss of field of view. The focusing device 206 can be used to focus the external light, that is, the light passing through the divergent device 110 can be completely focused by the focusing device 206 to the inside of the camera module 300 for imaging, which will neither produce a blurred image nor cause a loss of field of view.

[0055] In the present disclosure, the polarizer 203 in the display module 200 is a light-opaque device layer, but there are still light-opaque device layers such as the optical adhesive layer 202, the back layer 205, and the encapsulation layer 207 in the display module 200. Therefore, only the light-opaque device layer can be opened, for example, a through hole can be opened in the area of ​​the polarizer layer 203 corresponding to the diverging device 110; for the OLED flexible screen 204, due to the luminescent material, there is a certain influence on the propagation of light, and a through hole can also be opened in the area of ​​the OLED flexible screen 204 corresponding to the diverging device 110, so that light can pass through the display module 200.

[0056] In the present disclosure, light-transmitting device layers such as the optical adhesive layer 202, the back layer 205, and the encapsulation layer 207 can be set as complete device layers, that is, no through holes are set on the light-transmitting device layers such as the optical adhesive layer 202, the back layer 205, and the encapsulation layer 207. Such a setting not only does not affect the passage of light, but also further increases the strength of the display module 200 due to the integrity of the optical adhesive layer 202, the back layer 205, the encapsulation layer 207, etc.

[0057] In the present disclosure, the backlight layer 205 is disposed as the bottom layer of the display module 200 , and the encapsulation layer 207 is disposed on the upper side of the backlight layer 205 .

[0058] In one embodiment, if Figure 3As shown, a first protrusion 208 protruding downward can be formed on the lower surface of the backlight layer 205 to form a focusing device 206. Specifically, by polishing the backlight glass on the backlight layer 205, a first protrusion 208 with a focusing function of a plano-convex lens structure is formed, which can focus the light passing through the diverging device 110. The backlight glass can be made of LTPS (low temperature polycrystalline silicon material), and such a setting can increase the light transmittance of the backlight layer 205 and improve the camera function of the terminal device.

[0059] In one embodiment, if Figure 4 As shown, a second protrusion 209 protruding upward can be formed on the upper surface of the encapsulation layer 207 to form a focusing device 206. Specifically, by processing the encapsulation layer 207, a second protrusion 209 with a plano-convex lens structure is formed to focus the light passing through the diverging device 110. The encapsulation layer 207 can be rigid or flexible. When the encapsulation layer 207 is rigid, it can be made of glass material, and when the encapsulation layer 207 is flexible, it can be made of polyimide material.

[0060] In one embodiment, if Figure 5 As shown, a first protrusion 208 can be formed on the lower surface of the backlight layer 205, and a second protrusion 209 can be formed on the upper surface of the packaging layer 207, that is, a double convex lens structure can be formed. Such a setting can further enhance the focusing effect of the focusing device 206 and further expand the field of view of the camera module 300.

[0061] Based on the same inventive concept, the present disclosure also provides a terminal device, including all the technical features of any of the aforementioned embodiments.

[0062] The terminal device disclosed herein may be a mobile phone, a tablet or other terminal device.

[0063] The terminal device provided by the present disclosure can expand the field of view of the camera module by setting the divergent device, thereby being able to reduce the field of view of the camera module while maintaining the shooting range required by the terminal device, so that the camera module can be set below the display module without having to extend the camera module into the opening, so that the opening of the display module can be smaller, the display range can be larger, and the field of view of the camera module can be larger, achieving a better shooting effect. At the same time, because the camera module no longer extends into the opening of the display module, the display module is prevented from being damaged by the impact of the camera module during use, and the quality is better.

[0064] The foregoing description of the implementation of the present disclosure has been given for the purpose of illustration and description. The foregoing description is not exhaustive nor is it intended to limit the present disclosure to the exact form disclosed, and various variations and modifications may exist in accordance with the above teachings or may be obtained from the practice of the present disclosure.
