Description

Technical Field

[0001] The utility model relates to the technical field of display, and in particular to a display device, an electronic device and a car. Background Art

[0002] With the continuous development of the national economy, people's demand for electronic equipment is increasing, and the demand for display devices is also getting higher and higher. Display devices usually include panel components and mounting shells. In recent years, in the production process of display devices, some use VHB tape to bond and fix the panel components to the mounting shell. This method can directly bond the VHB tape, which is convenient to operate and does not require waiting for too long after bonding. The assembly efficiency is high, but due to the poor environmental tolerance of VHB tape, the high or low temperature adhesion is not strong enough, causing the panel component and the mounting shell to be basically separated. Some use silicone structural adhesive to bond and fix the panel component to the mounting shell. It has excellent environmental tolerance and a wide temperature tolerance range. It can even achieve a high adhesion at -50°C and 200°C. However, this silicone structural adhesive needs to be cured during the production process, and some even need to stand for 4-5 hours before it can be completely cured. Obviously, it prolongs the production process of the entire display device and is not conducive to mass production. Therefore, it is necessary to develop a new manufacturing method for the instrument panel. Utility Model Content

[0003] Based on the above situation, the main purpose of the present invention is to provide a display device, an electronic device and a car, so as to shorten the production time of the display device and improve the production efficiency.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0005] A first aspect of the utility model provides a display device, comprising a panel assembly and a mounting shell; the panel assembly comprises a glass cover plate and a display screen, the display screen is attached to the inner side of the glass cover plate, exposing the edge area of ​​the glass cover plate;

[0006] The mounting shell has a first bonding area and a second bonding area on the inner side of the edge portion thereof, and the first bonding area and the second bonding area are respectively distributed along the circumference of the mounting shell; the first bonding area is provided with a VHB tape, and the second bonding area is provided with a silicone structural adhesive strip;

[0007] The panel assembly is installed on the installation shell, the glass cover is located on the outside, the glass cover is pressed and bonded to the installation shell in the first bonding area through the VHB tape, and is pressed and bonded to the installation shell in the second bonding area through the silicone structural adhesive strip.

[0008] Preferably, the first bonding area is located outside the second bonding area.

[0009] Preferably, in the first bonding area, the VHB tape is arranged in multiple sections at intervals.

[0010] Preferably, a plurality of mounting grooves are arranged at intervals along the circumference of the mounting shell in the first bonding area, and the VHB tape is adhered to each of the mounting grooves.

[0011] Preferably, at least one second bonding area is provided along the circumference of the shell, and in each of the second bonding areas, the silicone structural adhesive strip is continuously provided along the circumference of the shell.

[0012] Preferably, two display screens are arranged side by side and at intervals along the length direction of the glass cover plate, and a middle area of ​​the glass cover plate is exposed between the two display screens;

[0013] The inner side surface of the mounting shell also has a third bonding area, and the third bonding area is arranged corresponding to the middle area. The third bonding area is provided with a silicone structural adhesive strip. When the panel assembly is installed on the mounting shell, the glass cover plate is also pressed and bonded to the mounting shell in the third bonding area through the silicone structural adhesive strip.

[0014] Preferably, glue grooves are provided in both the second bonding area and the third bonding area, and the silicone structural adhesive strip is located in the glue grooves.

[0015] Preferably, a plurality of the glue grooves are arranged side by side in the third bonding area along the length direction, and the glue grooves located in the second bonding area are connected to at least one glue groove located in the third bonding area.

[0016] A second aspect of the present invention provides an electronic device, comprising the display device as described in any one of the above items.

[0017] A third aspect of the present invention provides a car, comprising the electronic device as described above.

[0018] In the display device of the utility model, the panel assembly and the mounting shell are simultaneously adhered by VHB tape and silicone structural adhesive strip. In the manufacturing process of the display device, after the panel assembly and the mounting shell are adhered by VHB tape and silicone structural adhesive strip, since the ambient temperature during the manufacturing process is neither too high nor too low, the adhesion of the VHB tape is sufficient, and therefore there is no need to deliberately increase the waiting time for the silicone structural adhesive to cure, that is, the next step of the process can be carried out, thereby shortening the manufacturing time of the display device, improving production efficiency, and ensuring the reliability of the installation of the panel assembly and the mounting shell; and in the later testing and use process, even if the ambient temperature is high or low, since the curing time of the silicone structural adhesive strip is generally 4 to 5 hours, the silicone structural adhesive strip has already been cured within such a long time, and its bonding force has strong tolerance to the environment, and can still ensure the bonding force between the panel assembly and the mounting shell, and ensure the reliability of the connection between the two. It can be seen that the utility model improves the tolerance of the bonding force between the panel assembly and the mounting shell to the ambient temperature through the use of VHB tape and silicone structural adhesive strips, reduces the repair problem of the display device due to debonding, and improves the production efficiency and yield rate of the entire display device. At the same time, since the silicone structural adhesive strip has a large tolerance for the assembly gap between the panel assembly and the mounting shell, the combination of VHB tape and silicone structural adhesive can make the force uniform throughout the display assembly, thereby reducing the occurrence of MURA phenomenon for display devices, especially large-sized display devices.

[0019] Other beneficial effects of the utility model will be explained through the introduction of specific technical features and technical solutions in the specific implementation manner. Through the introduction of these technical features and technical solutions, those skilled in the art should be able to understand the beneficial technical effects brought about by the technical features and technical solutions.

[0029] The present invention is described below based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid confusing the essence of the present invention, known methods, processes, procedures, and components are not described in detail.

[0030] In addition, persons of ordinary skill in the art will appreciate that the drawings provided herein are for illustration purposes and are not necessarily drawn to scale.

[0031] Unless the context clearly requires otherwise, throughout the specification and claims, the words "include", "comprising" and similar words should be interpreted in an inclusive sense rather than an exclusive or exhaustive sense; that is, in the sense of "including but not limited to".

[0032] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0033] The utility model provides a method for manufacturing a fully laminated screen assembly, which can be applied to the manufacture of panel assemblies on various electronic devices, such as electronic devices such as automobile instruments, automobile central control, intelligent display terminals or mobile terminals, which have panel assemblies, including fully laminated assemblies, and fully laminated screen assemblies 100 include fully laminated first panels 110 and second panels 120, and the first panels 110 and the second panels 120 are laminated by optical adhesive, that is, an optical adhesive layer is provided between the first panel 110 and the second panel 120. Among them, the above-mentioned first panel 110 and the second panel 120 can be selected from any one of a segment code screen, a color screen, a touch screen and a glass cover plate, that is, the first panel 110 and the second panel 120 in the fully laminated screen assembly of the present application can be fully laminated between a segment code screen and a color screen, or fully laminated between a segment code screen and a touch screen, fully laminated between a segment code screen and a glass cover plate, fully laminated between a color screen and a glass cover plate, or fully laminated between a touch screen and a glass cover plate. It should be noted that some panel assemblies include a segment code screen, a color screen and a glass cover plate at the same time, some panel assemblies include a segment code screen, a touch screen and a glass cover plate at the same time, or some panel assemblies include a color screen, a touch screen and a glass cover plate at the same time, or some panel assemblies include a segment code screen, a color screen, a touch screen and a glass cover plate at the same time. No matter which type of panel assembly it is, the method of the present application can be used to first fully bond two of the panels that need to be fully bonded to form a fully bonded assembly, and then the manufacturing method of the present application can be used to fully bond this fully bonded assembly with another panel that needs to be fully bonded. It’s just that in the latter manufacturing method, one of the first panel and the second panel is actually not a simple panel, but a fully bonded assembly formed in the previous full bonding.

[0034] The utility model provides a display device, which can be applied to a variety of electronic devices, such as large-sized display screens, or smaller-sized automobile instrument panels and automobile central control devices. Figure 1-Figure 3 As shown, the display device includes a panel assembly 10 and a mounting shell 20. The panel assembly 10 includes a glass cover plate 11 and a display screen 12. The display screen 12 is attached to the inner side of the glass cover plate 11, exposing the edge area of ​​the glass cover plate. The mounting shell 20 has a first bonding area and a second bonding area on the inner side of its edge portion, and the first bonding area and the second bonding area are respectively distributed along the circumference of the mounting shell 20. The first bonding area is provided with a VHB tape 30, and the second bonding area is provided with a silicone structural adhesive strip 40. The panel assembly 10 is installed on the mounting shell 20, and the glass cover plate 11 is located on the outside, that is, the display screen 12 is located between the glass cover plate 11 and the mounting shell 20. The glass cover plate 11 is pressed and bonded to the mounting shell 20 by the VHB tape 30 in the first bonding area, and pressed and bonded to the mounting shell 20 by the silicone structural adhesive strip 40 in the second bonding area.

[0035] In the display device of the above embodiment, the panel assembly 10 and the mounting shell 20 are simultaneously adhered by the VHB tape 30 and the silicone structural adhesive strip 40. During the manufacturing process of the display device, after the panel assembly 10 and the mounting shell 20 are adhered by the VHB tape 30 and the silicone structural adhesive strip 40, since the ambient temperature during the manufacturing process is neither too high nor too low, the adhesion of the VHB tape is sufficient, and therefore, there is no need to deliberately increase the waiting time for the silicone structural adhesive 40 to cure, that is, the next step can be carried out, thereby shortening the manufacturing time of the display device, improving production efficiency, and ensuring the reliability of the installation of the panel assembly 10 and the mounting shell 20; and in the later testing and use process, even if the ambient temperature is high or low, since the curing time of the silicone structural adhesive strip is generally 4 to 5 hours, the silicone structural adhesive strip has already cured within such a long time, and its adhesive force has a strong tolerance to the environment, therefore, even if the adhesive force of the VHB tape decreases at this time, it can still ensure the adhesive force of the panel assembly 10 and the mounting shell 20, and ensure the reliability of the connection between the two. It can be seen that the utility model improves the tolerance of the bonding force between the panel assembly 10 and the mounting shell 20 to the ambient temperature through the use of the VHB tape 30 and the silicone structural adhesive strip 40, reduces the rework problem of the display device due to debonding, and improves the production efficiency and yield rate of the entire display device. At the same time, through this structure, since the silicone structural adhesive strip has a large tolerance for the assembly gap between the panel assembly 10 and the mounting shell 20, the combination of the VHB tape and the silicone structural adhesive strip 40 can make the force uniform at all parts of the display assembly 10, so that for the display device, especially a large-sized display device, the occurrence of the MURA phenomenon can also be reduced.

[0036] It should be noted that the display screen 12 may be a structure including only a display panel, or a combination of a display panel and a touch panel. The glass cover plate 12 may be a structure including only a glass plate, or a combination of an explosion-proof film and a glass plate. The glass cover plate 11 and the display screen 12 may be bonded by full bonding, or by using a frame glue, or by other bonding methods of the glass cover plate 11 and the display screen 12 in the prior art.

[0037] Among them, the first bonding area and the second bonding area can be respectively provided with a plurality of first bonding areas and a plurality of second bonding areas are arranged at intervals along the circumference of the mounting shell 20. In this way, the VHB tape 30 and the silicone structural strip 40 are arranged at intervals along the circumference of the mounting shell 20, that is, the VHB tape 30 and the silicone structural strip 40 are on the circumferential circle of the mounting shell 20, and they together form a circumference.

[0038] In a preferred embodiment, the first bonding area is located outside the second bonding area, that is, at the edge of the mounting shell, the first bonding area is closer to the outer edge of the mounting shell 20 than the second bonding area, the VHB tape 30 is outside, and the silicone structural adhesive strip 40 is inside. With this structure, during the manufacturing process of the display device, before the silicone structural adhesive strip 40 is cured, the connection reliability of the panel assembly 10 and the mounting shell 20 at the edge can be better guaranteed, thereby ensuring the connection reliability of the entire panel assembly 10 and the mounting shell 20.

[0039] In an embodiment where the first bonding area is located outside the second bonding area, the VHB tape 30 can be continuously arranged along the first bonding area. In a preferred manner, in the first bonding area, the VHB tape 30 is arranged in multiple sections at intervals. In this way, on the one hand, it can avoid the VHB tape 30 from generating wrinkles at the corners of the mounting shell 20, which affects the stress of the panel assembly 10. On the other hand, through this interval arrangement, the VHB tape 30 can have sufficient deformation space during the process of pressing the panel assembly 10 and the mounting shell 20, so that the stress of the panel assembly 10 can be more uniform after installation, which not only improves the installation reliability of the panel assembly 10 and the mounting shell 20, but also can better reduce the probability of the MURA phenomenon.

[0040] Furthermore, in order to prevent the VHB tape 30 from uncontrollably shifting due to weakened adhesion when the temperature is too high or too low, in a preferred embodiment of the utility model, a plurality of mounting grooves (not shown in the figure) are arranged at intervals along the circumference of the mounting shell 20 in the first bonding area, and the VHB tape 30 is adhered to each mounting groove, that is, the number of the VHB tape 30 is the same as the number of the mounting grooves, and the VHB tape 30 is adhered to each mounting groove one by one. Of course, one mounting groove may also be arranged, such as an annular mounting groove along the circumference of the mounting shell 20, and a plurality of VHB tapes are arranged at intervals in the annular mounting groove.

[0041] At the edge portion of the mounting shell, along the circumference of the shell 20, at least one second bonding area may be provided, that is, only one second bonding area may be provided, that is, the second bonding area may be provided along the circumference of the mounting shell 20 for a circle, or two or more second bonding areas may be provided, that is, two or more second bonding areas are provided at intervals along the circumference of the mounting shell 20, and multiple second bonding areas as a whole surround the circumference of the mounting shell 20 for a circle. Of course, the second bonding areas are on the same circle of the mounting shell 20, no matter it is one or more, the second bonding areas may be provided on multiple circles.

[0042] In a preferred embodiment, no matter which of the above methods is used to set the second bonding area, the silicone structural adhesive strips 40 are continuously arranged along the circumference of the housing 20 in each second bonding area, that is, a silicone structural adhesive strip is arranged in each second bonding area. This structure can better increase the connection reliability between the panel assembly 10 and the mounting housing 20 after the silicone structural adhesive strip is cured.

[0043] In order to increase the controllability of the silicone structural adhesive strip 40 before curing, and thus increase the connection reliability between the panel assembly 10 and the mounting shell 20 after curing, in some preferred embodiments of the present invention, the inner side of the mounting shell 20 is provided with an adhesive groove, such as Figure 2 As shown, a glue groove is provided in the second bonding area. When two or more glue grooves are provided in the second bonding area at intervals along the circumference of the mounting shell 20, a glue groove is provided in each second bonding area; when one glue groove is continuously provided in the second bonding area along the circumference of the mounting shell 20, one glue groove on the second bonding area is also provided along the circumference of the mounting shell 20, that is, the glue groove is an annular groove.

[0044] In the present invention, the display screen 12 may be provided with only one, such as Figure 2 As shown, in this embodiment, the display screen 12 is in the middle area of ​​the glass cover plate 11 , exposing the edge area of ​​the glass cover plate 11 . In this embodiment, the VHB tape 30 and the silicone structural adhesive 40 are only arranged on the edge portion of the mounting shell 20 .

[0045] In some embodiments, the display screen 12 is provided with a plurality of, for example, two, that is, the display screens are arranged side by side and spaced apart along the length direction of the glass cover plate 11, such as Figure 3 As shown, the two display screens 12 are both attached to the glass cover plate 11, and the middle area of ​​the glass cover plate 11 is exposed between the two display screens 12. This method can increase the convenience of use for users. Among them, the display screen 12 is usually a flat structure, and the two display screens 12 can be in the same plane, or the two display screens 12 can be arranged at an angle, such as an obtuse angle. When the two display screens 12 are arranged at an angle, the mounting shell 20 also includes a first mounting portion and a second mounting portion, and the first mounting portion and the second mounting portion are bent at an angle. When the panel assembly 10 is installed in the mounting shell 20, the two display screens 12 correspond to the first mounting portion and the second mounting portion respectively, and the exposed middle area of ​​the glass cover plate 11 is opposite to the bent portion of the mounting shell 20.

[0046] In this embodiment, the inner side of the mounting shell 20 also has a third bonding area, and the third bonding area is arranged corresponding to the middle area, that is, the third bonding area is opposite to the exposed middle area of ​​the glass cover plate 11, and the third bonding area is provided with a silicone structural adhesive strip 40. When the panel assembly 10 is installed on the mounting shell 20, the glass cover plate 11 is also pressed and bonded to the mounting shell 20 in the third bonding area through the silicone structural adhesive strip 40. By adding the third bonding area, the panel assembly 10 and the mounting shell 20 are not only bonded at the edge part, but also the bonding force is increased in the middle part of the mounting shell 20, so that the connection reliability between the panel assembly 10 and the mounting shell 20 can be further improved, especially when the size of the display assembly 10 is relatively large, this effect is more prominent, and the probability of the occurrence of the MURA phenomenon can be further reduced. When the two display screens 12 are arranged at an angle, the third bonding area is located at the bent portion of the mounting shell 20, where it is adhered to the panel assembly 10 through the silicone structural adhesive strip 40. Since the silicone structural adhesive strip 40 has a relatively high tolerance, even if the gap between the exposed middle area of ​​the glass cover plate 11 and the bent portion (i.e., the middle portion) of the mounting shell 20 is uneven, excellent bonding strength between the middle area and the bent portion can be achieved, thereby reducing the manufacturing accuracy of the mounting shell 20 and reducing the production cost.

[0047] In the third bonding area, a plurality of silicone structural adhesive strips 40 may be provided, and the plurality of silicone structural adhesive strips 40 are arranged side by side along the length direction of the mounting shell 40, such as Figure 3 As shown, the silicone structural strip 40 located in the second bonding area can be connected to the silicone structural strip 40 located in the third bonding area, which not only improves the convenience of coating the silicone structural strip 40 during the assembly process of the display device, but also can form the bonding force of the edge part and the bonding force of the middle part into a whole, thereby better improving the reliability of the connection between the panel assembly 10 and the mounting shell 20.

[0048] Further, the multiple silicone structural adhesive strips 40 in the third bonding area can be divided into a first group close to the first mounting portion and a second group close to the second mounting portion, and the multiple silicone structural adhesive strips 40 in each group are connected to each other end to end, and the silicone structural adhesive strip 40 farthest from the first mounting portion in the first group is connected to the silicone structural adhesive strip 40 located at the edge portion and arranged circumferentially along the first mounting portion, and the silicone structural adhesive strip 40 farthest from the second mounting portion in the second group is connected to the silicone structural adhesive strip 40 located at the edge portion and arranged circumferentially along the second mounting portion. With this structure, the operability of the gluing process can be further increased, thereby improving the operating efficiency.

[0049] A glue groove may also be provided in the third bonding area. The glue groove in the third bonding area may be provided according to the setting position of the silicone structural adhesive strip 40, that is, when there are multiple silicone structural adhesive strips 40, there are also multiple glue grooves, and each glue groove is bonded with a silicone structural adhesive strip 40; in some embodiments where the silicone structural adhesive strips 40 are connected end to end, the glue grooves for accommodating these silicone structural adhesive strips 40 are connected end to end; in the embodiment where the silicone structural adhesive strip 40 in the second bonding area is connected to at least one silicone structural adhesive strip 40 in the third bonding area, the glue groove in the second bonding area is also connected to at least one glue groove in the third bonding area. In this way, the controllability of the silicone structural adhesive strip 40 before solidification can be increased through the connected glue grooves, and the silicone structural adhesive strips 40 in the interconnected glue grooves can be better called a whole, so as to avoid excessive dispersion of the pressure flow of the silicone structural adhesive strip 40 during the pressing process of the panel assembly 10 and the mounting shell 20, thereby reducing the reliability of the connection between the panel assembly 10 and the mounting shell 20.

[0050] Of course, a VHB tape 20 may also be provided in the third bonding area.

[0051] In addition, the utility model also provides an electronic device, including the display device described in any of the above embodiments, and the electronic device can be a car dashboard, a car central control, an intelligent display terminal or a mobile terminal.

[0052] The utility model also provides a car, which comprises the electronic device described in any one of the above embodiments.

[0053] Those skilled in the art will appreciate that, without conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0054] It should be understood that the above-mentioned embodiments are merely illustrative and not restrictive. Without departing from the basic principles of the present invention, various obvious or equivalent modifications or substitutions that can be made by technicians in this field to the above details will be included in the scope of the claims of the present invention.
