However, it should be clear to those skilled in the art that the present application may also be implemented in other embodiments without these specific details.

[0045] It should also be understood that the term “and / or” used in the specification and appended claims refers to any and all possible combinations of one or more of the associated listed items, and includes these combinations.

[0046] As used in the specification and appended claims of this application, the term "if" can be interpreted as "when" or "uponce" or "in response to determining" or "in response to detecting", depending on the context. Similarly, the phrase "if it is determined" or "if [described condition or event] is detected" can be interpreted as meaning "uponce it is determined" or "in response to determining" or "uponce [described condition or event] is detected" or "in response to detecting [described condition or event]", depending on the context.

[0047] In addition, in the description of the present application specification and the appended claims, the terms "first", "second", "third", etc. are only used to distinguish the descriptions and cannot be understood as indicating or implying relative importance.

[0048] References to "one embodiment" or "some embodiments" etc. described in the specification of this application mean that one or more embodiments of the present application include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0049] It can be considered that the display device has gone through a long and arduous journey from the early black and white world to the color world, and the types of display devices have become more and more detailed, and 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 attracted widespread attention. OLED displays are displays that use organic light-emitting diodes as display screens. Due to their own self-luminescence without backlight, OLED displays have the characteristics of lighter and thinner appearance design, wider visual angle, faster response speed, and lower power consumption.

[0050] In order to ensure the display effect of the display device, a double-sided adhesive tape or an easy-to-pull adhesive tape is usually used to fix the display panel of the display device on the back plate to achieve the flatness and stability of the display device.

[0051] However, in actual applications, when the display device needs to be disassembled for inspection or maintenance, it is first necessary to separate the display panel from the back panel surface. However, there are many problems with the existing solutions for fixing the back panel and the display panel. Taking a 150-micron thick easy-to-pull tape as an example, the tensile strength does not exceed 25N / 10mm; the adhesion is poor, not exceeding 40N / 25mm; and there is a high risk of residual glue, and the tape itself is prone to cracking or breaking, which makes it inconvenient to disassemble the display panel and is prone to damage.

[0052] Based on this, an embodiment of the present application provides a display device, Figure 1 is a structural block diagram of a display device provided by an embodiment of the present application, such as Figure 1 As shown, including:

[0053] Display panel 1, used for displaying images;

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

[0055] The display panel is adhered to the back plate by an adhesive arranged on the first surface of the light-transmitting area, wherein the first surface is a surface parallel to the display panel 1 and close to one side of the display panel 1, and the adhesive 3 is configured as an adhesive that reduces viscosity when sensing ultraviolet light.

[0056] Specifically, the adhesive 3 is arranged on the first surface of the light-transmitting area, and is used to adhere the display panel 1 to the back plate 2, wherein the first surface is a surface parallel to the display panel 1 and close to one side of the display panel 1. Of course, the adhesive 3 can also be applied to the position corresponding to the light-transmitting area on the display panel, so as to achieve adhering the display panel to the back plate through the adhesive arranged in the light-transmitting area.

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

[0058] The structure of the back panel 2 can be configured according to actual needs, wherein at least part of the area of ​​the back panel 2 can be arranged as a light-transmitting area. The specific material and size of the light-transmitting area are not limited. For example, the entire area of ​​the back panel 2 can be arranged as a light-transmitting area, or part of the back panel 2 can be hollowed out to form a light-transmitting area. The light-transmitting area can be directly hollowed out or installed with corresponding transparent components. The specific situation of the light-transmitting area is not further elaborated here.

[0059] In this embodiment, an adhesive 3 may be provided on the first surface of the light-transmitting region to adhere the display panel 1 to the back plate 2 . The first surface may refer to a surface in the light-transmitting region that is parallel to the display panel 1 and close to one side of the display panel 1 .

[0060] As an example, the adhesive 3 in the embodiment of the present application can be understood as an adhesive whose viscosity decreases when it senses ultraviolet light. For example, the adhesive 3 can be understood as an adhesive whose viscosity decreases under ultraviolet light and is easy to remove, while its viscosity under light other than ultraviolet light is greater than its viscosity under ultraviolet light.

[0061] Due to the use of the adhesive 3, when the display panel is subsequently disassembled, the viscosity between the display panel and the back plate can be reduced by irradiating with ultraviolet light, thereby completing the disassembly of the display panel quickly and safely. The adhesive 3 can cover the entire area of ​​the first surface, or can cover a partial area of ​​the first surface, as long as it can ensure that the display panel 1 is adhered to the back plate 2.

[0062] In a possible embodiment of the present application, a plurality of light-transmitting areas may be provided on the back plate 2 .

[0063] Exemplarily, the adhesive 3 can be made of UV pressure-sensitive debonding glue, which can include the following raw materials in parts 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°C to -20°C, and the molecular weight distribution can be 1.01-2.3.

[0064] Among them, 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; the photoinitiator can be one or more of free radical photoinitiator or cationic photoinitiator.

[0065] This embodiment does not limit the specific setting process of the adhesive 3. For example, a UV-type pressure-sensitive viscosity-reducing glue can be coated on the first surface of the light-transmitting area, and the thickness of the glue coating can be 5μm-20μm; after drying the UV-type pressure-sensitive viscosity-reducing glue, a release film can be applied, and then matured for 2-3 days at a temperature of 50℃-70℃.

[0066] In a possible implementation of the present application, there is also a buffer layer between the adhesive 3 and the display panel 1. The buffer layer may have a certain deformation ability, which is used to buffer the connection between the display panel 1 and the back panel 2, to prevent the display panel 1 from being damaged during installation or removal, and to further ensure the firmness of the display panel 1; the material of the buffer layer may be sponge, etc. Alternatively, the transparent component installed in the light-transmitting area of ​​this embodiment may also have a certain deformation ability, directly achieving the same effect as the buffer layer, while simplifying the structure of the back panel, which is not limited in this embodiment.

[0067] Furthermore, after the adhesive 3 is set on the first surface of the light-transmitting area, the display panel 1 can be directly fixed on the back panel 2 using the adhesive 3, or a buffer layer can be set between the display panel 1 and the adhesive 3, and both sides of the buffer layer can be covered with the adhesive 3 respectively, or other adhesives can be set on both sides of the buffer layer, or other adhesives can be set on the side of the buffer layer away from the adhesive 3, so that the display panel 1 is adhered to the side of the buffer layer covered with the adhesive 3, thereby fixing the display panel 1 on the back panel 2.

[0068] By utilizing the above-mentioned technical solution of this embodiment, the display panel is adhered to the back plate by using an adhesive, wherein the adhesive is configured as an adhesive that reduces viscosity when sensing ultraviolet light. When the display panel of the display device needs to be disassembled, light irradiation can be used to reduce the viscosity between the display panel and the back plate, thereby facilitating the disassembly of the display panel and reducing damage to the display panel, thereby achieving the technical effect of simplifying the disassembly operation and improving the efficiency and safety of the display panel disassembly.

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

[0070] The light-shielding medium at least covers the second surface of the light-transmitting area and is used to block the light entering the adhesive through the outside of the second surface. The second surface is parallel to the display panel and away from the display panel.

[0071] Among them, the shading medium can be set on the second surface of the light-transmitting area, and can be used to block the light that enters the adhesive through the outside of the second surface. The material and size of the shading medium are not limited here. For example, the shading medium can include shading tape, or other media that can block light.

[0072] Therefore, different operations can be performed on the shading medium according to the needs of the display device. For example, when the display device is working, by setting a shading medium on the second surface of the light-transmitting area, the shading medium can be used to block the light entering the adhesive from outside the light-transmitting area, thereby protecting the viscosity of the adhesive from being reduced and ensuring the firmness of the display panel. When the display device needs to be disassembled, the shading medium set on the second surface can be removed, such as tearing off the shading tape set on the second surface, and by continuously irradiating the second surface of the light-transmitting area with ultraviolet light from outside the light-transmitting area, the light can pass through the light-transmitting area to the adhesive. When the adhesive senses the ultraviolet light, its own viscosity can be reduced. Therefore, when the viscosity between the display panel and the back panel is reduced, the display panel can be disassembled. On this basis, by setting a shading medium, it is possible to ensure the firmness of the display panel when the display device is working, and when the display panel of the display device needs to be disassembled, it is possible to facilitate the disassembly of the display panel, reduce damage to the display panel, and achieve the technical effect of simplifying the disassembly operation.

[0073] In some embodiments, the backplane is composed of a backplane body and a light-transmitting area, a transparent component is installed in the light-transmitting area, and the backplane body is the part of the backplane excluding the light-transmitting area.

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

[0075] Accordingly, when a part of the backplane is arranged as a light-transmitting area, the adhesive 3 of this embodiment can be arranged on the first surface of the transparent component, and the arrangement method can cover the entire area of ​​the first surface with the adhesive 3. On this basis, by arranging the backplane as a backplane body and a device with a light-transmitting area of ​​a transparent component 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 achieve the technical effect of simplifying the disassembly operation.

[0076] In some embodiments, the back panel has at least one light-transmitting area, and the display device provided by the embodiment of the present application further includes:

[0077] A rear cover and a logic component, wherein a light-transmitting area and a logic component are arranged in the rear cover, and the logic component is connected to the display panel.

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

[0079] As an example, the number of light-transmitting areas on the back panel can be one or more. During the specific configuration process, one of the light-transmitting areas and the logic component can be set in the back shell. The logic component can be set or pasted on the surface of the back panel body. The size and position of the specific logic component can be configured according to actual needs. For example, the logic component can be set on the surface of the back panel body away from the display panel. Furthermore, the logic component can have a communication connection with the display panel through various network connection methods, such as data transmission through Ethernet connection or optical fiber connection, or communication through Wi-Fi or Bluetooth connection, etc. On this basis, the protection of the logic component can be achieved according to the different back panel structures.

[0080] Figure 2 is a structural block diagram of another display device provided by an embodiment of the present 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 with a transparent component 5 installed, the number of transparent areas can be three, the first surface of the transparent component 5 installed in each transparent area can be provided with a UV debonding layer (i.e., adhesive 3), and the display panel 1 is adhered to the back panel through a buffer layer 6, and the second surface of the transparent component 5 installed in each transparent area is provided with a shading tape 7 (i.e., shading medium).

[0081] The logic component 81 and the rear shell 9 protecting the logic component 81 can be arranged 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 arranged in the rear shell 9, and 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 local 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 by the embodiment of the present application further includes:

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

[0084] As another example, the number of light-transmitting areas on the back panel can be one or more. In the specific configuration process, the logic component can be set inside the transparent component installed in at least one light-transmitting area. For example, the circuit on the surface of the logic component can be made in one of the transparent components, and then the display panel and one of the transparent components are connected to realize the communication connection between the logic component and the display panel. Alternatively, 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 multiple transparent components. On this basis, by eliminating the setting of the back shell, the thickness of the display device is reduced, making the display device more lightweight and beautiful.

[0085] Figure 3 is a structural block diagram of another display device provided by an embodiment of the present application, such as Figure 3 As shown, when the number of light-transmitting areas on the backplane is 3, the logic component 82 can be made in a transparent component in one of the light-transmitting areas, and then connected to the display panel through the transparent component to achieve communication connection between the logic component and the display panel.

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

[0087] Among them, polymer materials may include thermoplastic plastics PS, organic glass acrylic PMMA and other materials, the thickness of the transparent component may be greater than the thickness of the backplane body, and the cross section of the transparent component may be an I-shaped, and then the whole backplane can be obtained directly by secondary injection molding the backplane body and the transparent component. On this basis, it is possible to ensure strict inlaying of the transparent component and the backplane body to a certain extent, improve the quality of the backplane, increase the bonding area between the display panel and the backplane, and further ensure the firmness of the bonding of the display panel.

[0088] Figure 4 is a structural block diagram of another display device provided by an embodiment of the present application, such as Figure 4 As shown, the cross section of the transparent component 10 can be configured as an I-shape, and can be embedded into the back panel body 4 to form the overall structure of the back panel.

[0089] In some embodiments, the transparent component is made of glass. The display device of the embodiment of the present application further includes:

[0090] The ring frame is used to fix the transparent component, wherein the thickness of the transparent component is equal to the thickness of the back plate body, and the material of the ring frame is a polymer material.

[0091] In a specific implementation, the transparent component can be made of glass material with high hardness and transparency, and the thickness of the transparent component is equal to the thickness of the back panel body. Accordingly, when installing the transparent component, a ring frame made of polymer material can be used to wrap the edge of the transparent component to fix and protect the transparent component. For example, 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 while ensuring the strict inlay of the transparent component and the back panel body, thereby enriching the structure of the back panel.

[0092] The back panel can be obtained by secondary injection molding of the light-transmitting component, the ring frame and the back panel body. For example, the specific molding process can be to first mold the back panel body and the ring frame, and then put the glass in for secondary molding, or it can be to use a mold with a support pin to fix the glass at the opening of the back panel body, and directly perform injection molding to obtain the back panel.

[0093] Figure 5 is a structural block diagram of another display device provided by an embodiment of the present application, such as Figure 5 As shown, the transparent component 11 can be a glass strip, the thickness of the glass strip is equal to the thickness of the back panel body, which can ensure the accuracy of the transparent component and facilitate the installation of the transparent component; two ring frames 12 are arranged around the transparent component 11 to enable the transparent component 11 to be installed in the back panel body 4.

[0094] In some embodiments, the transparent component is made of polymer material or glass, and the transparent component is fixed to the light-transmitting area by double-sided tape.

[0095] In a specific embodiment, the transparent component can be pasted on the light-transmitting area of ​​the back panel, such as by fixing the transparent component on the light-transmitting area through double-sided tape. At the same time, the thickness of the transparent component can be greater than the thickness of the back panel body, and the cross-section of the transparent component can be an inverted T-shape. On this basis, the fixation of the transparent component can be facilitated by posting double-sided tape internally, and by setting the cross-section of the transparent component to be an inverted T-shape, the firmness of the transparent component can be guaranteed to a certain extent, the strict inlay of the transparent component can be achieved, and the quality of the back panel is further improved.

[0096] Figure 6 is a structural block diagram of another display device provided by an embodiment of the present application, such as Figure 6 As shown, the back panel body can be a metal body with a partial window. Double-sided tape 14 can be used on the outside of the window to fix the transparent component 13 in the light-transmitting area; the thickness of the transparent component 13 can be greater than the thickness of the back panel body 4, and the cross-section of the transparent component 13 can be an inverted T shape.

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

[0098] In a specific embodiment, the back panel body can be pre-set with a groove, and the transparent component is embedded in the set groove to form a light-transmitting area; the number and depth of the grooves can be determined by relevant personnel based on empirical values, the length and width of the embedded transparent component can be consistent with the groove, and the depth of the transparent component can be configured according to needs. For example, the thickness of the transparent component can be equal to the depth of the groove, that is, the transparent component can fit completely with the groove, thereby ensuring that the back panel has good sealing; 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, thereby reducing the situation of unexpected debonding of the adhesive and ensuring the safety of the display panel.

[0099] Figure 7 is a partial structural block diagram of another display device provided by an embodiment of the present application, such as Figure 7 As shown, the back plate body 4 may be provided with a groove, so that the transparent component 15 may be embedded in the groove. In the figure, the thickness of the transparent component is smaller than the depth of the groove.

[0100] In some embodiments, the entire area of ​​the back plate is arranged as a light-transmitting area, and the material of the back plate is a light-transmitting material. The display device of the embodiment of the present application further includes:

[0101] The rubber frame is arranged around the back panel to fix and protect the back panel.

[0102] In a specific embodiment, all areas of the backplane can be arranged as light-transmitting areas, that is, the overall structure of the backplane has a light-transmitting function, and the material of the backplane is a light-transmitting material, wherein the light-transmitting material can be a new composite material that can transmit visible light, infrared light and ultraviolet light, such as inorganic light-transmitting materials, polymer light-transmitting materials and light-transmitting composite materials; the rubber frame can be considered as the edge strip of the backplane, which has a certain degree of flexibility and durability, and can be set around the backplane to fix and protect the backplane to prevent the edge of the backplane from being worn and broken; the specific material of the rubber frame can include rubber, silicone rubber and polyurethane. Furthermore, the logic component can be directly configured on the surface or inside of the backplane, and the specific position can be configured according to actual conditions.

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

[0104] The rear shell and the logic component, a part of the back plate and the logic component are arranged in the rear shell, and the logic component is connected to the display panel.

[0105] As an example, when the entire area of ​​the backplane is arranged as a light-transmitting area, the logic component can be configured in a partial area of ​​the backplane, such as being pasted on a partial surface of the backplane body. In order to protect the logic component, the logic component and a partial area around the logic component can be set in the back shell, and the logic component and the display panel can be connected to each other through various network connection methods. On this basis, the protection of the logic component can be achieved according to the different backplane structures.

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

[0107] The logic component is arranged inside the backplane, and the backplane is connected to the display panel.

[0108] As another example, when the entire area of ​​the backplane is arranged as a light-transmitting area, the logic component can be directly configured inside the backplane, thereby connecting to the display panel through the backplane to achieve communication connection between the logic component and the display panel. On this basis, according to different backplane structures, by eliminating the setting of the rear shell, the thickness of the display device can be reduced, making the display device more lightweight and beautiful.

[0109] Optionally, in this embodiment, the material of the back plate may be glass, and the plastic frame may be used to fix the glass to protect the glass from damage.

[0110] Accordingly, the adhesive can be arranged on the first surface of the back plate parallel to the display panel and close to one side of the display panel, and the coverage area of ​​the adhesive can ensure that the display panel 1 is adhered to the back plate, such as the adhesive can be laid on multiple areas of the first surface respectively, which can ensure the firmness of the display panel. On this basis, by setting the entire area of ​​the back plate as a light-transmitting material, the structure of the display device can be simplified while facilitating the installation and disassembly of the display device, and at the same time, it is more convenient to cover the adhesive.

[0111] Figure 8 is a structural block diagram of another display device provided by an embodiment of the present application, such as Figure 8 As shown, the back plate 16 can be made of glass as a whole, and the glass back plate is wrapped and fixed by the adhesive frame 17. Among them, multiple local areas can be selected on the first surface of the back plate 16 as the covering area of ​​the adhesive, and a light shielding tape can be attached to the opposite side of the first surface.

[0112] The following is an exemplary description of the preparation and disassembly of the display device, taking the display device as an organic light emitting diode display as an example:

[0113] The preparation process of the organic light-emitting diode display may include: first preparing the back panel of the organic light-emitting diode display, such as using the back panel as a movable mold to perform secondary molding to prepare a transparent area; or first performing secondary molding to prepare a glass edge plastic strip, and then fixing the glass and the back panel body through the glass edge plastic strip; or using the glass-based back panel as an insert, and combining it with a secondary molding rubber frame as an integral back panel; or using double-sided tape to fix the transparent component to the back panel body.

[0114] Then, a light-shielding tape can be applied to the opposite surface of the backplane with the transparent application area; a UV debonding composite double-sided tape can be applied to the transparent OLED side; secondly, the OLED display panel can be assembled, that is, the display panel can be attached to the backplane. Finally, the logic components and the back cover can be assembled to complete the overall preparation of the OLED display.

[0115] Furthermore, when the OLED display needs to be disassembled, the light-shielding tape on the second surface of the back panel can be torn off, and UV can be irradiated to the second surface to debond the adhesive layer, so that the OLED display panel can be removed, and the OLED display can be disassembled and repaired.

[0116] From the above description, it can be found that the back panel in a display device provided in this embodiment has a light-transmitting area. By setting an adhesive on the first surface of the light-transmitting area, the display panel and the back panel can be adhered together, thereby achieving fixation of the display panel and the back panel, and solving the problems of insufficient adhesion and easy breaking in the existing easy-to-pull tape solution.

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