However, it will be apparent to those skilled in the art that the present application can be practiced in other embodiments that depart from these specific details.

[0045] It is also to be understood that the terminology "and / or" when used in this specification and in the following claims, refers to at least one of the items, or any combination of the items, and includes all possible combinations when used in the description of items.

[0046] As used in this specification and in the claims, the term "if" can be construed to mean "when" or "once" or "in response to a determination" or "in response to the occurrence of an event" that is to be taken in the context of this specification. Similarly, the phrase "if it is determined" or "if [a described condition or event] is detected" can be construed to mean "once it is determined" or "in response to a determination" or "once [the described condition or event] is detected" or "in response to the detection that [a described condition or event]".

[0047] In addition, in the description of the application and in the claims, the terms "first", "second", "third", etc. are used merely as labels for the purpose of distinguishing between different features, and are not intended to indicate or imply relative importance of the respective features.

[0048] Reference within the specification of this application to "one embodiment" or "some embodiments" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the application. The appearances of the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," or other similar phrases in the specification of this application are not necessarily all referring to the same embodiment, but are instead meant to connote "one or more but not all of the embodiments" unless otherwise indicated. The terms "including," "comprising," "having," and variations thereof are meant to encompass the items listed thereafter but do not exclude additional, unrecited items.

[0049] It can be considered that from the early black and white world to the color world, the display device has undergone a long and arduous journey, and the types of display devices are more and more detailed, which can be divided into cathode ray tube displays, plasma displays, liquid crystal displays, etc. For example, in recent years, the demand for high brightness, high definition, large screen, high efficiency and low power display devices has increased more and more, and OLED displays have been widely concerned. OLED display is a display that uses organic light-emitting diodes as a display screen. Since it is self-luminous and does not use backlight, it has a lighter and thinner appearance design, a wider visual viewing angle, a faster response speed, and lower power consumption.

[0050] In order to ensure the display effect of the display device, the display panel of the display device is usually fixed on the back plate by using double-sided adhesive tape or easy-to-pull adhesive tape to realize the flatness and stability of the display device.

[0051] However, in actual application, when disassembling the display device for inspection or maintenance, the separation work of the display panel and the surface of the back plate needs to be carried out first, but the existing scheme for fixing the back plate and the display panel has many problems. For example, the tensile strength of the 150-micron-thick easy-to-pull adhesive tape is not more than 25 N / 10 mm; the adhesion is poor, and the adhesion is not more than 40 N / 25 mm; and there is a high risk of residual glue, which is easy to crack or break, so that it is inconvenient to disassemble the display panel, and the display panel is easy to be damaged.

[0052] Based on this, the embodiments of the application provide a display device, Figure 1 is a structural block diagram of a display device provided by an embodiment of the application, as Figure 1 shown, comprising:

[0053] The display panel 1 is used to display images.

[0054] The back plate 2 is placed parallel to the display panel 1 and is used to support the display panel 1, wherein at least part of the area of the back plate 2 is arranged as a light-transmitting area.

[0055] The display panel is pasted on the back plate by the adhesive agent arranged on the first surface of the light-transmitting region, wherein the first surface is the surface parallel to the display panel 1 and close to one side of the display panel 1, and the adhesive agent 3 is configured as an adhesive agent with reduced viscosity in the state of responding to ultraviolet light.

[0056] Specifically, the adhesive agent 3 is arranged on the first surface of the light-transmitting region, and is used for pasting the display panel 1 on the back plate 2, wherein the first surface is the surface parallel to the display panel 1 and close to one side of the display panel 1. Of course, the adhesive agent 3 can also be coated on the display panel at a position corresponding to the light-transmitting region, so as to realize pasting the display panel on the back plate by the adhesive agent arranged on the light-transmitting region.

[0057] In the embodiment, the display panel 1 can refer to the panel used for displaying images in the display device; the back plate 2 can be the plate behind the display panel 1, responsible for supporting the internal circuit and components, and can be placed parallel to the display panel 1 of the display device, used for supporting the display panel 1, for example, the plane where the back plate 2 is located can be parallel to the plane where the display panel 1 is located, without common intersection, or the distance between the back plate 2 and the display panel 1 can be controlled within a certain range.

[0058] The structure of the back plate 2 can be configured according to actual needs, wherein at least part of the area of the back plate 2 can be arranged as a light-transmitting region, and the specific material and size of the light-transmitting region are not limited, for example, the entire area of the back plate 2 can be arranged as a light-transmitting region, or the back plate 2 can be partially hollowed out to form a light-transmitting region, and the light-transmitting region can be directly in a hollow state or be provided with a corresponding transparent component, and the specific conditions of the light-transmitting region are not further described herein.

[0059] The embodiment can be provided with the adhesive agent 3 on the first surface of the light-transmitting region, so as to paste the display panel 1 on the back plate 2, and the first surface can refer to the surface parallel to the display panel 1 and close to one side of the display panel 1 in the light-transmitting region.

[0060] As an example, the adhesive agent 3 in the embodiment of the present application can be understood as an adhesive agent with reduced viscosity in the state of responding to ultraviolet light, for example, the adhesive agent 3 can be understood as an adhesive agent with viscosity reduced under ultraviolet light and easy to remove, and the viscosity under other light except ultraviolet light is greater than that under ultraviolet light.

[0061] Due to the use of the adhesive agent 3, the viscosity between the display panel and the back plate can be reduced by irradiation of ultraviolet light during subsequent disassembly of the display panel, so that the disassembly of the display panel is quickly and safely completed. The adhesive agent 3 can cover the entire area of the first surface, or can cover part of the area of the first surface, as long as it can ensure that the display panel 1 is pasted on the back plate 2.

[0062] In a possible embodiment of the present application, the backboard 2 can be provided with multiple light-transmitting regions.

[0063] For example, the adhesive 3 can be made of a UV type pressure-sensitive adhesive, which can include the following raw materials by weight: 100 parts of acrylate pressure-sensitive adhesive, 50-70 parts of UV prepolymer, 1-3 parts of curing agent, 8-10 parts of photoinitiator, 40-60 parts of solvent, and 0.1-3 parts of leveling agent. The molecular weight of the acrylate pressure-sensitive adhesive can be 380,000-680,000, the glass transition temperature can be -40℃ to -20℃, and the molecular weight distribution can be 1.01-2.3.

[0064] The UV prepolymer can be one or more of polyurethane (meth) acrylate, polyester (meth) acrylate, and polyether (meth) acrylate; the curing agent can be one or more of polyisocyanate curing agent, epoxy curing agent, and organic peroxide curing agent; and the photoinitiator can be one or more of free radical type photoinitiator or cationic type photoinitiator.

[0065] The present embodiment does not limit the process of specifically setting the adhesive 3. For example, the UV type pressure-sensitive adhesive can be coated on the first surface of the light-transmitting region, and the thickness of the adhesive coating can be 5μm-20μm. After drying the UV type pressure-sensitive adhesive, a release film can be covered, and then the curing is performed at a temperature of 50℃-70℃ for 2-3 days.

[0066] In a possible implementation of the present application, the adhesive 3 and the display panel 1 further have a buffer layer. The buffer layer can have a certain deformation ability, which is used to buffer the connection between the display panel 1 and the backboard 2, prevent the display panel 1 from being damaged during installation or disassembly, and further ensure the firmness of the display panel 1. The material of the buffer layer can be sponge or the like. Alternatively, the transparent component installed in the light-transmitting region in the present embodiment can also have a certain deformation ability, which directly achieves the same effect of the buffer layer and simplifies the structure of the backboard. The present embodiment does not limit this.

[0067] Further, after the adhesive 3 is set on the first surface of the light-transmitting region, the display panel 1 can be directly fixed on the backboard 2 by using the adhesive 3, or a buffer layer can be set between the display panel 1 and the adhesive 3. The two sides of the buffer layer can be respectively covered with the adhesive 3, or other adhesives can be set on the two sides of the buffer layer, or other adhesives can be set on the side of the buffer layer far from the adhesive 3, so as to paste the display panel 1 on the side of the buffer layer covered with the adhesive 3, thereby achieving the fixation of the display panel 1 on the backboard 2.

[0068] By using the above technical solutions of the embodiment, the display panel is pasted on the back plate by using the adhesive, the adhesive is configured as an adhesive with reduced viscosity in the state of sensing ultraviolet light, and when the display panel of the display device needs to be disassembled, the viscosity between the display panel and the back plate can be reduced by using light irradiation, the disassembly of the display panel is facilitated, the damage to the display panel is reduced, the technical effect of simplifying the disassembly operation is achieved, and the efficiency and safety of the display panel disassembly are improved.

[0069] In some embodiments, the display device of the embodiment of the application further comprises:

[0070] The light-shielding medium covers at least the second surface of the light-transmitting region and is used to shield light from the outside that enters the adhesive through the second surface. The second surface is a surface that is parallel to the display panel and away from the display panel.

[0071] The light-shielding medium can be arranged on the second surface of the light-transmitting region and can be used to shield light from the outside that enters the adhesive through the second surface. The material and size of the light-shielding medium are not limited here. For example, the light-shielding medium can include a light-shielding adhesive tape or other light-shielding medium.

[0072] Therefore, different operations can be performed on the light-shielding medium according to the needs of the display device. For example, when the display device is working, the light-shielding medium arranged on the second surface of the light-transmitting region can be used to shield light from the outside that enters the adhesive through the second surface, so as to protect the viscosity of the adhesive and ensure the firmness of the display panel. When the display device needs to be disassembled, the light-shielding medium arranged on the second surface can be removed, such as tearing off the light-shielding adhesive tape arranged on the second surface, and the second surface of the light-transmitting region can be continuously irradiated by ultraviolet light from the outside of the light-transmitting region, so that light can pass through the light-transmitting region and enter the adhesive. The adhesive can reduce its viscosity in the state of sensing ultraviolet light, so that the display panel can be disassembled in the case of reduced viscosity between the display panel and the back plate. On this basis, by arranging the light-shielding medium, the firmness of the display panel can be ensured when the display device is working, and the disassembly of the display panel can be facilitated when the display panel of the display device needs to be disassembled, so as to reduce the damage to the display panel and achieve the technical effect of simplifying the disassembly operation.

[0073] In some embodiments, the back plate is composed of a back plate body and a light-transmitting region, the transparent component is arranged in the light-transmitting region, and the back plate body is a part of the back plate other than the light-transmitting region.

[0074] The backplate body can be considered as the main structure of the backplate 2 and can carry other components as a substrate. The backplate body can be made of metal or other materials other than metal. The light-transmitting area can be understood as an area formed by partially hollowing out the backplate 2 and installing a transparent component in the hollowed-out area. The size and shape of the light-transmitting area are not limited and can be determined according to the actual situation of the backplate 2 and the display panel 1 or can be different based on the material of the transparent component. The transparent component is a component made of transparent material, and the specific material and thickness are not limited and can be configured differently according to different needs.

[0075] Correspondingly, when part of the area of the backplate is arranged as a light-transmitting area, the adhesive 3 of the present embodiment can be arranged on the first surface of the transparent component, and the arrangement can be such that the adhesive 3 covers the entire area of the first surface. On this basis, by arranging the backplate as a backplate body and a device with a light-transmitting area in which the transparent component is installed, the adhesive 3 is arranged on the transparent component, which can reduce the cost of the display device while ensuring the firmness of the display panel, and at the same time, the technical effect of simplifying the disassembly operation is achieved.

[0076] In some embodiments, the backplate has at least one light-transmitting area, and the display device provided by the present embodiment further comprises:

[0077] The backshell and the logic component, wherein one light-transmitting area and the logic component are arranged in the backshell, and the logic component is connected to the display panel.

[0078] The logic component can be an important component for controlling the operation of the display device, and can include components such as a controller and a driving circuit. The controller is mainly responsible for receiving signals from external devices, decoding and processing these signals, and sending the processed signals to the driving circuit to control the image display of the display device. The controller can include a microprocessor, a video memory, and an interface circuit. The driving circuit is mainly responsible for converting the input signals into appropriate electrical signals for display and controlling parameters such as brightness, contrast, and refresh rate of the display panel. The driving circuit can include a scanning circuit and a timing control circuit. The backshell can be used to protect the logic component and ensure the stability and durability of the display device.

[0079] As an example, the back panel can have one or more light-transmitting areas. In specific configurations, one of these areas, along with the logic components, can be housed within the back cover. The logic components can be mounted or attached to the surface of the back panel body. The size and position of the logic components can be configured according to actual needs; for example, the logic components can be placed on the surface of the back panel body away from the display panel. Furthermore, the logic components can communicate with the display panel via various network connection methods, such as data transmission via Ethernet or fiber optic connections, or communication via Wi-Fi or Bluetooth. Based on this, protection for the logic components can be achieved depending on the back panel structure.

[0080] Figure 2 This is a structural block diagram of another display device provided in an embodiment of this application, such as... Figure 2 As shown, the specific type of the display panel 1 can be an OLED display panel. The back panel can include a back panel body 4 and a light-transmitting area on which transparent components 5 are installed. There can be three transparent areas. The first surface of the transparent component 5 installed in each transparent area can be provided with a UV release layer (i.e., adhesive 3), and the display panel 1 is pasted onto the back panel through a buffer layer 6. The second surface of the transparent component 5 installed in each transparent area is provided with a light-shielding tape 7 (i.e., light-shielding medium).

[0081] The logic component 81 and the rear shell 9 protecting the logic component 81 can be disposed on the rear surface of the back panel body 4, that is, one of the light-transmitting areas and the logic component 81 can be disposed inside the rear shell 9. The logic component 81 can have a communication connection with the display panel 1 through a connecting line, and the connecting line can pass through the partial wire hole between the back panel body 4 and the transparent component 5.

[0082] In some embodiments, the back panel has at least one light-transmitting area, and the display device provided in this application embodiment further includes:

[0083] A logic component is disposed inside a transparent component mounted in at least one light-transmitting area, wherein the transparent component mounted in one of the light-transmitting areas is connected to the display panel.

[0084] As another example, the number of light-transmitting regions on the backboard can be one or more, and in the process of specific configuration, the logic component can be arranged inside the transparent component installed with at least one light-transmitting region, such as the circuit on the surface of the logic component can be made in one of the transparent components, and then the display panel and the one transparent component are connected to realize the communication connection between the logic component and the display panel, or the specific content of the logic component can be dispersed in multiple transparent components, and the communication connection between the logic component and the display panel is realized through the connection between the display panel and the multiple transparent components. On this basis, by canceling the setting of the back cover, the thickness of the display device is reduced, so that the display device is more portable and beautiful.

[0085] Figure 3 is a structural block diagram of another display device provided by an embodiment of the present application, as shown in Figure 3 When the number of light-transmitting regions on the backboard is three, the logic component 82 can be made in the transparent component of one of the light-transmitting regions, and then the transparent component and the display panel are connected to realize the communication connection between the logic component and the display panel.

[0086] In some embodiments, the material of the transparent component is a high polymer material, and the backboard is obtained by secondary injection molding of the backboard body and the transparent component.

[0087] For example, the high polymer material can include thermoplastic plastic PS, organic glass acrylic PMMA and other materials, the thickness of the transparent component can be greater than the thickness of the backboard body, the cross section of the transparent component can be H-shaped, and then the whole backboard can be obtained by secondary injection molding of the backboard body and the transparent component. On this basis, the strict inlaying of the transparent component and the backboard body can be ensured to a certain extent, the quality of the backboard is improved, the bonding area of the display panel and the backboard is increased, and the firmness of the display panel bonding is further ensured.

[0088] Figure 4 is a structural block diagram of another display device provided by an embodiment of the present application, as shown in Figure 4 The cross section of the transparent component 10 can be configured as H-shaped, and the whole structure of the backboard can be formed by inlaying into the backboard body 4.

[0089] In some embodiments, the material of the transparent component is glass, and the display device of the embodiment of the present application further comprises:

[0090] The ring frame is used for fixing the transparent component, wherein the thickness of the transparent component is equal to the thickness of the backboard body, and the material of the ring frame is a high polymer material.

[0091] In the specific embodiment, the transparent component can adopt a glass material with high hardness and transparency, the thickness of the transparent component is equal to the thickness of the backboard body, and accordingly, when the transparent component is installed, a ring frame with a high polymer material can be used to wrap the edge of the transparent component to fix and protect the transparent component, such as the ring frame can be located around the transparent component or only wrap the top corner of the transparent component. On this basis, the strength and transparency of the transparent component can be improved on the basis of ensuring the strict inlaying of the transparent component and the backboard body, and the structure of the backboard is enriched.

[0092] The backboard can be obtained by performing secondary injection molding on the light-transmitting component, the ring frame, and the backboard body. For example, the specific molding process can be to first perform molding operation on the backboard body and the ring frame, and then perform secondary molding on the glass, or the mold with a support pin for fixing the glass at the opening of the backboard body can be used to directly perform injection molding to obtain the backboard.

[0093] Figure 5 is a structural block diagram of another display device provided by an embodiment of the present application, as shown in Figure 5 The transparent component 11 can be a glass strip, the thickness of the glass strip is equal to the thickness of the backboard body, the accuracy of the transparent component can be ensured, and the installation of the transparent component is facilitated; the transparent component 11 is surrounded by two ring frames 12 to install the transparent component 11 in the backboard body 4.

[0094] In some embodiments, the material of the transparent component is a high polymer material or glass, and the transparent component is fixed in the light-transmitting area by double-sided adhesive.

[0095] In the specific embodiment, the transparent component can be pasted on the light-transmitting area of the backboard, such as the transparent component can be fixed on the light-transmitting area by double-sided adhesive, the thickness of the transparent component can be greater than the thickness of the backboard body, and the cross section of the transparent component can be inverted T-shaped. On this basis, the double-sided adhesive inside can facilitate the fixation of the transparent component, and by setting the cross section of the transparent component to be inverted T-shaped, the firmness of the transparent component can be ensured to a certain extent, the strict inlaying of the transparent component is realized, and the quality of the backboard is further improved.

[0097] In some embodiments, the backboard body is provided with a groove, and the transparent component is inlaid in the groove, and the thickness of the transparent component is less than or equal to the depth of the groove.

[0098] In the specific embodiment, the backboard body can be provided with a groove in advance, and the transparent component is inlaid in the set groove to form the light transmission region. The number and depth of the groove can be determined by relevant personnel according to the experience value. The length and width of the inlaid transparent component can be consistent with the groove. The depth of the transparent component can be configured according to the requirement. For example, the thickness of the transparent component can be equal to the depth of the groove, that is, the transparent component can completely fit the groove, so as to ensure that the backboard has good sealing performance. The thickness of the transparent component can also be less than the depth of the groove, so that when the adhesive is set, the adhesive can be partially set in the groove and partially set above the groove, so as to reduce the unintended debonding of the adhesive and ensure the safety of the display panel.

In the figure, the thickness of the transparent component is less than the depth of the groove. Figure 7

[0100] In some embodiments, the entire area of the backboard is arranged as a light transmission region, the material of the backboard is a light transmission material, and the display device provided by the embodiment of the present application further includes:

[0101] The rubber frame is arranged around the backboard and is used for fixing and protecting the backboard.

[0102] In the specific embodiment, the entire area of the backboard can be arranged as a light transmission region, that is, the entire structure of the backboard has a light transmission function, and the material of the backboard is a light transmission material. The light transmission material can be a new type of composite material capable of transmitting visible light, infrared light and ultraviolet light, such as an inorganic light transmission material, a polymer light transmission material and a light transmission composite material. The rubber frame can be considered as a binding strip of the backboard and has a certain flexibility and durability. The rubber frame can be arranged around the backboard and is used for fixing and protecting the backboard to prevent the edge of the backboard from being abraded and broken. The specific material of the rubber frame can include rubber, silicone rubber and polyurethane. Further, the logic component can be directly configured on the surface or in the interior of the backboard, and the specific position can be configured according to the actual situation.

[0103] In some embodiments, the display device provided by the embodiment of the present application further includes:

[0104] The back shell and the logic component are arranged in the back shell, and the logic component is connected with the display panel.

[0105] ​As an example, when the entire back panel is designed to be translucent, the logic components can be configured in a portion of the back panel, such as by attaching them to a portion of the back panel's surface. To protect the logic components, the logic components and a surrounding area can be housed within the back cover, allowing the logic components to communicate with the display panel via various network connection methods. Based on this, protection for the logic components can be achieved depending on the back panel structure.

[0106] In some embodiments, the display device provided in this application further includes:

[0107] The logic components are located inside the back panel, which is connected to the display panel.

[0108] As another example, when the entire back panel is designed to be translucent, the logic components can be directly housed within the back panel, allowing them to connect to the display panel and establish communication between them. Furthermore, depending on the back panel structure, the thickness of the display device can be reduced by eliminating the need for a rear shell, resulting in a lighter and more aesthetically pleasing device.

[0109] Optionally, in this embodiment, the back panel can be made of glass, and the plastic frame can be used to fix the glass to protect it from damage.

[0110] Correspondingly, the adhesive can be applied to a first surface of the backplate, parallel to and close to the display panel. The coverage area of ​​the adhesive is sufficient to ensure that the display panel 1 can be adhered to the backplate. Alternatively, the adhesive can be applied to multiple areas of the first surface to ensure the display panel is firmly attached. Furthermore, by making the entire backplate a light-transmitting material, the structure of the display device can be simplified while facilitating installation and removal, and the application of adhesive is also made easier.

[0111] Figure 8 This is a structural block diagram of another display device provided in an embodiment of this application, such as... Figure 8 As shown, the back panel 16 can be made entirely of glass, and is wrapped and fixed by a frame 17. Multiple local areas can be selected on the first surface of the back panel 16 as areas covered by adhesive, and light-blocking tape can be applied to the opposite side of the first surface.

[0112] The following description, using an organic light-emitting diode (OLED) display as an example, illustrates the fabrication and disassembly of the display device:

[0113] The fabrication process of an organic light-emitting diode (OLED) display may include: firstly fabricating the backplate of the OLED display, such as using the backplate as a moving mold to form the transparent area in a secondary molding process; or first forming the glass-edge plastic strip in a secondary molding process, and then using the glass-edge plastic strip to fix the glass to the backplate body; or using a glass-based backplate as an insert, combined with a secondary molding frame as the overall backplate; or using double-sided adhesive tape to fix the transparent components to the backplate body.

[0114] Then, light-shielding tape can be applied to the opposite surface of the backplate with the transparent bonding area; UV-resistant double-sided adhesive can be applied to the OLED side of the transparent area; next, the OLED display panel can be assembled, that is, the display panel can be attached to the backplate. Finally, the logic components and back cover can be assembled to complete the overall fabrication of the OLED display.

[0115] Furthermore, when it is necessary to disassemble the OLED display, the light-shielding tape on the second surface of the back panel can be peeled off, and UV light can be irradiated onto the second surface to cause the adhesive layer to detach, thereby allowing the OLED display panel to be removed and the OLED display to be disassembled and repaired.

[0116] As can be seen from the above description, the back panel of the display device provided in this embodiment has a light-transmitting area. By providing an adhesive on the first surface of the light-transmitting area, the display panel and the back panel can be glued together, thereby fixing the display panel and the back panel and solving the problems of insufficient adhesion and easy breakage in the existing easy-pull tape solution.

[0117] Meanwhile, a light-shielding tape is provided on the second surface of the light-transmitting area. When it is necessary to disassemble the display device, especially when disassembling the display panel, the light-shielding tape can be removed and ultraviolet light can be irradiated locally onto the second surface of the light-transmitting area. This can achieve rapid debonding of the adhesive layer, facilitate the disassembly of the display panel, prevent or reduce damage to the display panel, and improve the efficiency and safety of the display panel disassembly.
