Description

Technical Field

[0001] The present invention relates to display technology, and particularly to a display device. Background Art

[0002] With the development of the portable electronic device (such as mobile phone, tablet computer, e-book, and navigation device) industry, the camera under panel (CUP) technology has gradually become a development trend due to the better visual experience and the interference-free all-round display it brings.

[0003] In the existing CUP display device, the display panel in the display area corresponding to the camera (abbreviation: camera area) is a small transparent screen. When not taking pictures, the camera area can normally display the screen content; when taking pictures, the camera area becomes a transparent film.

[0004] In such a CUP display device, the camera is attached to the display panel through an optical adhesive. During the attachment process, the optical adhesive will fill the gap between the lens and the housing of the camera to flatten the side of the lens facing the display panel for convenient attachment. However, due to the characteristics of the existing optical adhesive, the existing light incident surface of the camera lens is an arc-shaped or uneven curved surface structure, and the optical adhesive cannot completely fill the tiny gap formed between the lens and the housing, resulting in a non-planar structure of the optical adhesive in the area of the light incident surface of the lens, and voids or bubbles will be formed between the optical adhesive and the light incident surface of the lens, affecting the imaging quality of the lens and the shooting effect of the camera under the screen.

[0039] Embodiment 1

[0040] Figure 1 is a schematic structural diagram of the display device provided by Embodiment 1 of the present invention, Figure 2 is a top view schematic diagram of the camera provided by Embodiment 1 of the present invention, Figure 3 is a schematic structural diagram of the camera provided by Embodiment 1 of the present invention; Figure 4 is Figure 3 the enlarged schematic diagram of part A in Figures 1-4As shown in the figure, Embodiment 1 of the present invention discloses a display device 10, including: a display panel 11; and a camera 30 adhered to one side of the display panel 11 through an optical adhesive 20. The camera 30 includes: a housing 32; a lens 31 fixedly accommodated in the housing 32; and a spacer 40 fixed to the side of the housing 32 facing the display panel 11 and completely covering the light incident surface of the lens 31. The first surface of the spacer 40 is adhered to one side of the display panel 11 through the optical adhesive 20, and the first surface is a flat surface. By providing a spacer 40 that covers the light incident area of the lens 31 of the camera 30 between the optical adhesive 20 and the camera 30, the display device 10 provided by the present invention avoids the problem of the degradation of the optical effect of the camera 30 caused by the direct covering of the lens 31 by the optical adhesive 20 on the display panel 11 during the adhesion process between the display panel 11 and the camera 30.

[0041] In this embodiment, the type of the display panel is, for example, an OLED display panel. The display panel 11 includes, for example: an array substrate and various film layer structures provided on the array substrate. The array substrate can be a flexible substrate or a rigid substrate, and its material includes one or more of glass, plastic, silicon dioxide, polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, polyimide, or polyurethane. Each film layer structure includes, for example: a pixel driving circuit layer, a light emitting layer, and a packaging layer. The pixel driving circuit layer, the light emitting layer, and the packaging layer are, for example, provided on one side of the array substrate; this side is, for example, the light emitting side of the display panel.

[0042] The display panel 11 includes, for example, a first display area and a second display area. The first display area of the display panel is, for example, a conventional display area, and the conventional display area includes, for example, a display function. The second display area of the display panel is, for example, a transmissive display area, and the transmissive display area includes, for example, a transmissive function and a display function. A camera 30 is provided on one side of the display panel 11, and this side is, for example, the backlight side of the display panel 11, and the camera 30 is provided corresponding to the second display area. When the display function is executed in the first display area, a plurality of pixel units located in the first display area emit light under the drive of a pixel driving circuit on the array substrate; when the display function is executed in the second display area, a plurality of pixel units located in the second display area emit light under the drive of a pixel driving circuit on the array substrate, and the camera 30 on one side of the transmissive display area is blocked by the transmissive display area and cannot be observed by a user or a terminal located on the side of the transmissive display area far from the camera 30. Furthermore, when both the second display area and the first display area execute the display function, the camera 30 on one side of the second display area can be hidden, and the display panel can achieve a full-screen display, that is, a true full-screen display; when the display function is executed in the first display area, a plurality of pixel units located in the first display area emit light under the drive of a pixel driving circuit on the array substrate, and when the transmissive function is executed in the second display area, the plurality of pixel units located in the second display area do not emit light, and the transmissive display area is in a transmissive state. The camera 30 on one side of the transmissive display area can receive ambient light incident on the second display area from the outside, thereby achieving normal light sensing, that is, the display panel has both a display function and a light sensing function while executing the display function.

[0043] In this embodiment, the camera 30 includes: a housing 32 and at least one lens 31 fixedly received in the housing 32. When the number of the lenses 31 is one, the camera 30 is a single camera module, and when the number of the lenses 31 is multiple, the camera 30 is a multi-camera module. In this embodiment, the specific composition of each lens 31 and the surface state of the light incident surface are not limited. Each lens 31 may be formed by laminating a plurality of optical lenses, and the surface state of the light incident surface of the lens 31 may be an arc or a curved surface including a plurality of concave and convex surfaces. In addition, the surface state of the light incident surface of the lens 31 may also be a plane. Since the side of the housing 32 facing the display panel 11 protrudes from the lens 31, when the light incident surface of the lens 31 is small, due to the characteristics of the optical glue (for example, high viscosity), when the display panel 11 is bonded to the camera 30 through the optical glue 20, there may still be a situation where the optical glue 20 in the area corresponding to the light incident surface of the lens 31 cannot fill the gap space formed by the housing 32 and the lens 31.

[0044] In this embodiment, the display device 10 further includes a spacer 40. The spacer 40 is fixed to the side of the housing 32 facing the display panel 11 and completely covers the light incident surface of the lens 31. The first surface of the spacer 40 is adhered to one side of the display panel 11 through the optical adhesive 20, and the first surface is a flat surface. Since the spacer 40 is disposed between the optical adhesive 20 and the camera 30, and the spacer 40 covers the light incident surface of the lens 31, and the first surface of the spacer 40 adhered to the optical adhesive 20 is a flat surface, when the display panel 11 is adhered to the camera 30 through the optical adhesive 20, the spacer 40 can make the optical adhesive 20 above the light incident surface of the corresponding lens 31 evenly coated, ensuring that the light incident from the outside to the lens 31 will not be affected by the optical adhesive 20, and at the same time avoiding the formation of bubbles or gaps between the optical adhesive 20 and the light incident surface of the lens 31, ensuring the imaging quality of the lens 31 and the shooting effect of the camera 30.

[0045] In this embodiment, the spacer 40 further includes a second surface disposed opposite to the first surface, and the second surface is parallel to the first surface. That is, the spacer 40 is a plate-like structure with a uniform thickness, so as to ensure that the light incident on the lens 31 will not be affected by the setting of the spacer 40, and ensure the optical effect of the camera 30.

[0046] In this embodiment, the spacer 40 is, for example, disposed parallel and opposite to the display panel 11. Since the spacer 40 is parallel to the display panel 11, the optical adhesive 20 can be disposed between the spacer 40 and the display panel 11 with a uniform thickness, ensuring that the light incident on the lens 31 will not be affected by the setting of the optical adhesive 20, and ensuring the optical effect of the camera 30.

[0047] In this embodiment, the spacer 40 is spaced from the lens 31. Specifically, the outer edge of the spacer 40 protrudes from the lens 31. At least one fixing groove 321 is provided on the surface of the housing 32 facing the display panel 11, and a first adhesive is provided in the fixing groove 321. The outer edge of the spacer 40 is fixedly connected to the housing 32 through the first adhesive, so that the spacer 40 can be stably disposed above the lens 31. The number of the fixing grooves 321 in this embodiment is not limited. When there is one fixing groove 321, it is, for example, an annular fixing groove as shown in the attached drawings of the specification of the present invention; when the number of the fixing grooves 321 is multiple, they are, for example, multiple groove structures spaced from each other on the surface of the housing 32 facing the display panel 11. The setting position of the fixing groove 321 in this embodiment is not limited, and it can be, for example, set as shown in the attached drawings of the specification of the present invention. Figure 2 As shown; when the number of the fixing grooves 321 is multiple, they are, for example, multiple groove structures spaced from each other on the surface of the housing 32 facing the display panel 11. The setting position of the fixing groove 321 in this embodiment is not limited, and it can be, for example, set as shown in the attached drawings of the specification of the present invention. Figure 2On the surface of the housing 32 facing the display panel 11 and at the adjacent position of the lens 31, or at the spaced position between the housing 32 facing the display panel 11 and the lens 31, as long as the setting of the fixing groove 321 and the first adhesive located in the fixing groove 321 does not affect the optical effect of the lens 31. In this embodiment, the material of the first adhesive is not limited, and it is, for example, a glue that is liquid at room temperature.

[0048] Furthermore, a positioning member 322 protruding towards the display panel 11 is also provided on the surface of the housing 32 facing the display panel 11. The positioning member 322 on the housing 32 abuts against the side edge of the outer edge of the spacer 40 to position and fix the spacer 40. Specifically, the positioning member 322 is fixed on the surface of the housing 32 facing the display panel 11 and is integrally formed with the housing 32. In other embodiments of the present invention, the positioning member 322 can also be detachably connected to the housing 32.

[0049] In this embodiment, the material of the spacer 40 is, for example, one or more of glass, plastic, silicon dioxide, polyethylene, polypropylene, polystyrene, polylactic acid, polyethylene terephthalate, polyimide, or polyurethane. Preferably, the spacer 40 has a certain rigidity to support the optical glue 20 located on the first surface of the spacer 40 during the process of bonding the display panel 11 and the camera 30 with the optical glue 20.

[0050] In this embodiment, the display device 10 further includes a functional film layer provided on the display panel 11. The functional film layer is provided on the side of the display panel 11 facing the camera 30, that is, the backlight side of the display panel 11. The functional film layer includes a back plate 12 and a heat dissipation layer 13. The back plate 12 is, for example, made of PET material, and the heat dissipation layer 13 is, for example, made of a high thermal conductivity metal material or an inorganic non-metallic material. Specifically, the back plate 12 is provided between the array substrate and the heat dissipation layer 13. Openings are provided on both the back plate 12 and the heat dissipation layer 13, so that the functional film layer forms a groove in the area corresponding to the second display area. The optical glue 20, the spacer 40, and the camera 30 are sequentially stacked on the backlight side of the display panel 11, and the spacer 40 and the optical glue 20 are both accommodated in the groove. In this embodiment, by providing a groove on the functional film layer on the backlight side of the display panel 11 and arranging the optical glue 20 and the spacer 40 in the groove, the problem that the thickness of the display device 10 increases due to the arrangement of the optical glue 20 and the spacer 40 is avoided. Moreover, the groove structure can reduce the number of film layers above the camera 30, improve the light transmittance of the second display area of the display panel 11 and the amount of incident light onto the lens 31 of the camera 30, and enhance the shooting effect of the camera 30.

[0051] Referring to Figure 1 , in this embodiment, the opening on the backplane 12 is the first opening, the opening on the heat dissipation layer 13 is the second opening, the groove includes the first opening formed by the backplane 12 at the position corresponding to the second display area and the second opening formed by the heat dissipation layer 13 at the position corresponding to the second display area. The size of the first opening is equal to the size of the second opening, that is, the cross-sectional area of the first opening is equal to the cross-sectional area of the second opening. The cross-sectional shape of the groove corresponds to the cross-sectional shape of the camera 30 or the spacer 40, the cross-sectional area of the groove is greater than or equal to the area of the optical adhesive 20, and the area of the optical adhesive 20 is greater than or equal to the area of the spacer 40.

[0052] Preferably, as Figure 1 shown, the size of the setting area of the optical adhesive 20 is, for example, greater than the size of the spacer 40. Since the size of the spacer 40 is greater than the size of the lens 31 and less than or equal to the size of the housing 32, the specific connection method is as follows. The optical adhesive 20 includes a first area at the central position and a second area at the periphery of the first area. The first area is adapted to the size of the spacer 40, and the optical adhesive 20 in the first area is directly bonded to the spacer 40. The optical adhesive 20 in the second area is directly bonded to the housing 32 and / or the positioning member 322 on the housing. Preferably, the projection of the second area on the surface of the housing 32 at least covers the positioning member 322 on the housing 32. The height of the positioning member 322 protruding from the surface of the housing 32 opposite to the display panel 11 is equal to the thickness of the spacer 40, so as to minimize the thickness of the display device while ensuring the positioning and fixing effect of the positioning member 322 on the spacer 40. Further, the positioning member 322 surrounds the periphery of the spacer 40 and jointly forms a closed accommodation space with the housing 32 and the optical adhesive 20. The volume of the accommodation space is adapted to the spacer 40, so that even when the adhesion effect between the spacer 40 and the first adhesive in the fixing groove 321 is poor, the spacer 40 can still be well fixed and sealed. In other embodiments of the present invention, since the volume of the accommodation space is adapted to the spacer 40, the fixing groove 321 and the first adhesive located in the fixing groove 321 can be omitted to save process steps and reduce process difficulty. Or, the fixing groove 321 may not be provided on the housing 32, and the first adhesive may be provided in the gap area between the positioning member 322 and the spacer 40, which can also achieve a good fixing and sealing effect on the spacer 40.

[0053] In other embodiments of the present application, the size of the setting area of the optical adhesive 20 may also be equal to the size of the spacer 40. In this case, the size of the spacer 40, the size of the optical adhesive 20, and the cross-sectional area of the groove are all equal. Thus, while achieving a good under-screen camera effect, the display device 10 avoids generating gaps between the backplane 12 and the heat dissipation layer 13 and the optical adhesive 20 and the spacer 40 due to the setting of the groove, thereby affecting the sealing effect of the display panel 11 and improving the waterproof and oxygen invasion effect of the display panel.

[0054] In this embodiment, a part of the camera 30 is recessed in the groove, and a part of it protrudes outside the groove area. Specifically, the housing 32 of the camera 30 is partially received in the groove, and the outer diameter of the housing is smaller than the cross-sectional area of the groove. However, in other embodiments of the present application, since the area of the camera 30 protruding from the groove is not limited by the size of the groove, the cross-sectional area of a part of the housing 32 of the camera 30 protruding from the groove can also be larger than the cross-sectional area of the groove, so that the volume of the camera 30 can be set larger, reducing the process difficulty.

[0055] In this embodiment, a second adhesive 80 is, for example, further provided around the housing 32. The second adhesive 80 is, for example, a UV adhesive. The UV adhesive, also known as a photosensitive adhesive or an ultraviolet light-curing adhesive, is a type of adhesive that can only be cured by ultraviolet light irradiation and has the characteristics of fast curing speed and strong bonding force. The housing 32 is fixedly connected to the display panel 11 through the second adhesive 80 to ensure stable bonding between the camera 30 and the display panel 11. The housing 32 is fixedly connected to the heat dissipation layer 13 of the display panel 11 through the second adhesive 80 to improve the heat dissipation effect of the camera 30 while ensuring stable bonding between the camera 30 and the display panel 11. Preferably, at least part of the second adhesive 80 is provided in the middle area between the heat dissipation layer 13 and the housing 32 located in the groove, thereby shortening the heat conduction path between the housing 32 and the heat dissipation layer and accelerating the heat dissipation speed of the housing 32.

[0056] In this embodiment, the camera further includes, for example, a filter disposed on the light incident side away from the lens 31, an image sensor, and a focusing motor disposed between the lens 31 and the housing 32. The filter may be disposed adjacent to the lens 31, and the image sensor is disposed on a side of the filter away from the lens 31. The filter is, for example, an infrared filter (IR-CUT dual filter). When the infrared sensing points outside the lens detect changes in the intensity of light, the built-in IR-CUT automatic switching filter can automatically switch accordingly according to the intensity of external light, so that the best imaging effect can be obtained whether the image is in the daytime or at night. The image sensor uses the photoelectric conversion function of optoelectronic devices to convert the optical image on the photosensitive surface into an electrical signal proportional to the optical image. In this embodiment, the type of the image sensor may be a CCD (Charge Coupled Device) sensor, a CMOS (Complementary Metal Oxide Semiconductor) sensor, or a CIS (Contant Image Sensor) sensor. It should be noted that in other embodiments of the present invention, the camera 30 may also be, for example, other cameras including lenses other than cameras, and the present invention is not limited thereto.

[0057] In this embodiment, the display device 10 further includes, for example, a polarizer 50 and a cover plate 60 sequentially stacked on the display panel 11. The polarizer 50 and the cover plate 60 are fixedly connected by an optical adhesive 21 disposed between the polarizer 50 and the cover plate 60.

[0058] In this embodiment, the OLED display panel is taken as an example for the display panel 11. However, in other embodiments of the present application, the type of the display panel may also be, for example, a Mini-LED display panel, a Micro-LED display panel, or a combination of the above display panel types.

Figure 6 is Figure 5 the enlarged schematic diagram at B in Figure 5 and Figure 6As shown in the figure, Embodiment 2 of the present invention discloses a display device 10, including: a display panel 11; and a camera 30 attached to one side of the display panel 11 through an optical adhesive 20. The camera 30 includes: a housing 32; a lens 31 fixedly received in the housing 32; and a spacer 40 fixed to the side of the housing 32 facing the display panel 11 and completely covering the light incident surface of the lens 31. The first surface of the spacer 40 is attached to one side of the display panel 11 through the optical adhesive 20, and the first surface is a flat surface. The display device provided by the present invention avoids the problem of the decline in the optical effect of the camera 30 caused by the optical adhesive 20 on the display panel 11 directly covering the lens during the process of attaching the display panel 11 to the camera 30 by providing a spacer 40 that covers the light incident area of the lens 31 of the camera 30 between the optical adhesive 20 and the camera 30.

[0061] The structure of the display device disclosed in this embodiment is similar to that of Embodiment 1. For the same parts, they will not be described in detail in this embodiment.

[0062] The difference is that at least one engaging member 41 is provided on the spacer 40. The engaging member 41 is, for example, provided on the side edge of the spacer 40 away from the display panel 11. At least one engaging groove 323 is provided on the surface of the housing 32 facing the display panel 11. The engaging groove 323 is adapted to the size of the engaging member 41 and corresponds to it in number one by one. The spacer 40 and the housing 32 are fixedly connected through the engaging member 41 and the engaging groove 323, so that the spacer 40 can be stably arranged above the lens 31. The engaging connection method between the spacer 40 and the housing 32 provided in the embodiment of the present invention can achieve a good fixing effect while ensuring the thinnest possible display device 10. And since no additional first adhesive is required, it has the advantage of simplifying the process steps. The number of the engaging grooves 323 is not limited in this embodiment. When there is one engaging groove 323, it is, for example, an annular fixing groove provided on the surface of the housing 32 facing the display panel 11. When the number of the engaging grooves 323 is multiple, they are, for example, multiple groove structures arranged at intervals on the surface of the housing 32 facing the display panel 11. The setting position of the engaging groove 323 is not limited in this embodiment. It can be, for example, set at the adjacent position of the surface of the housing 32 facing the display panel 11 and the lens 31, or at the spaced position of the surface of the housing 32 facing the display panel 11 and the lens 31, as long as the setting of the engaging groove 323 and the engaging member 41 located in the engaging groove 323 does not affect the optical effect of the lens 31.

[0063] It should be noted that in other embodiments of the present invention, there can be many other implementation manners for the multiple engaging members 41 on the spacer 40 and the multiple engaging grooves 323 on the housing 32. For example, a positioning member 322 protruding toward the display panel 11 is further provided on the surface of the housing 32 facing the display panel 11, and the side edge of the outer edge of the spacer 40 abuts against the positioning member of the housing 32 to position and fix the spacer 40. At least one engaging member protrudes from the side edge of the outer edge of the spacer 40, and engaging grooves corresponding to the number and size of the engaging members are provided in the positioning member 322 on the housing 32. The engaging member is fixedly connected to the engaging groove so that the spacer 40 can be stably disposed above the lens 31. The present invention does not list them one by one here.

[0064] Embodiment III

[0065] Figure 7 is a schematic structural diagram of the display device provided in Embodiment III of the present invention. As Figure 7 shown, Embodiment III of the present invention discloses a display device 10, including: a display panel 11; and a camera 30 attached to one side of the display panel 11 through an optical adhesive 20. The camera 30 includes: a housing 32; a lens 31 fixedly received in the housing 32; and a spacer 40 fixed to the side of the housing 32 facing the display panel 11 and completely covering the light incident surface of the lens 31. The first surface of the spacer 40 is attached to one side of the display panel 11 through the optical adhesive 20, and the first surface is a flat surface. The display device 10 provided by the present invention avoids the problem of the degradation of the optical effect of the camera 30 caused by the optical adhesive 20 on the display panel 11 directly covering the lens during the process of attaching the display panel 11 to the camera 30 by providing a spacer 40 covering the light incident area of the lens 31 of the camera 30 between the optical adhesive 20 and the camera 30.

[0066] The structure of the display device 10 disclosed in this embodiment is similar to that in Embodiment I and Embodiment II. For the same parts, they will not be described again in this embodiment.

[0067] In contrast, in this embodiment, the opening on the backplane 12 is the first opening, the opening on the heat dissipation layer 13 is the second opening, the groove includes the first opening formed by the backplane 12 at the position corresponding to the second display area and the second opening formed by the heat dissipation layer 13 at the position corresponding to the second display area, the size of the first opening is smaller than the size of the second opening, that is, a stepped structure is formed at the position of the backplane 12 and the heat dissipation layer 13 corresponding to the second display area of the display panel 11. The thickness of the optical glue 20 is equal to the thickness of the backplane 12, the housing 32 protrudes from the first opening of the backplane 12, and part of the housing 32 is received in the second opening of the groove, and at least part of the second adhesive 80 is disposed on the intermediate area between the heat dissipation layer 13 and the housing 32 located in the groove. Due to the stepped structure formed by the backplane 12 and the heat dissipation layer 13, the peripheral size of the camera 30 housing can be set larger, reducing the manufacturing cost of the camera 30. Moreover, since part of the housing 32 is recessed in the second opening, the camera 30 can be closer to the heat dissipation layer 13, thereby shortening the heat conduction path and improving the heat conduction efficiency.

[0068] The above has introduced in detail a display panel and a display device provided by an embodiment of the present invention. Specific examples are used herein to elaborate on the principle and implementation manner of the present invention. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those skilled in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
