Description

Technical Field

[0001] This utility model relates to the field of display packaging technology, and in particular to a display packaging structure and electronic device. Background Technology

[0002] Currently, with the development of technology, the displays in electronic devices such as laptops, tablets, mobile phones, and telephones are mostly fixed by adhesives. Common methods include fixing with tape or glue, which is placed between the screen and the casing. In tape bonding, the tape covers the frame, resulting in a larger bezel of the display screen, affecting the overall aesthetics. When disassembling with existing glue bonding, the current technology usually involves forcefully disassembling the display screen, which often leads to breakage and damage.

[0003] Therefore, it is necessary to propose an improvement to overcome the shortcomings of the existing technology. Utility Model Content

[0004] The purpose of this utility model is to solve the problems in the prior art by providing a display screen packaging structure and electronic device, which solves the problems of large bezels, poor aesthetics, and difficulty in disassembly after the display screen is packaged.

[0005] The technical solution of this utility model is:

[0006] A display screen packaging structure includes a display screen assembly, an adhesive layer, and a back cover. The adhesive layer is disposed between the display screen assembly and the back cover. The back cover has an adhesive pre-drilling hole, and an adhesive pre-drilling section is provided in the adhesive pre-drilling hole. The adhesive pre-drilling section is connected to the adhesive layer. The inlet of the adhesive pre-drilling hole is located on the corresponding dispensing area of ​​the back cover below the adhesive layer. The outlet of the adhesive pre-drilling hole and the inlet of the adhesive pre-drilling hole are not on the same plane.

[0007] The easy-open adhesive is initially in the form of glue. During the display encapsulation process, the easy-open adhesive is applied to the adhesive area on the back cover. The display assembly is then placed on the easy-open adhesive on the back cover, completing the encapsulation process. After curing, the easy-open adhesive forms a removable and deformable layer. During the application process, the easy-open adhesive enters through the inlet of the pre-drilled hole and flows towards the outlet side. After curing, the easy-open adhesive in the pre-drilled hole forms a pre-drilled section. This section is used for later maintenance and disassembly of the display. Pulling out the pre-drilled section removes the adhesive layer along with the pre-drilled section, severing the bond between the display and the back cover. The inlet and outlet of the pre-drilled hole are located on different planes, which improves upon the disadvantage of the outlet being on the front of the display bonding surface, reduces the width of the display obstruction frame, ensures a smaller bezel width for the display, and improves the overall aesthetics of the display.

[0008] As a preferred technical solution, the pre-drilled hole for the easy-open adhesive is a through-hole structure, with the inlet and outlet of the through-hole located at the upper and lower ends of the back cover, respectively.

[0009] The inlet of the through hole is located on the upper surface of the back cover, and the outlet of the through hole is located on the lower surface of the back cover. This not only reduces the width of the screen obstruction frame, but also reduces the number of openings on the visible surface of the screen, further improving the aesthetics of the visible surface of the screen and greatly enhancing the user experience.

[0010] As a preferred technical solution, the through hole is provided with a first reserved section for easy-pull adhesive, and the first reserved section for easy-pull adhesive is connected to the easy-pull adhesive layer.

[0011] When applying adhesive with easy-pull glue, the glue flows downward through the through hole to form the first pre-reserved section. During monitor maintenance, the easy-pull glue layer is pulled out along with the first pre-reserved section, thus disassembling the display screen from the back cover.

[0012] As a preferred technical solution, the pre-drilled hole for the easy-pull adhesive is a stepped hole structure, with the inlet end of the stepped hole located at the upper end of the back cover and the outlet end of the stepped hole located on the side of the back cover.

[0013] The stepped hole inlet is located on the upper surface of the back cover, and the stepped hole outlet is located on the side of the back cover. This reduces the width of the display screen obstruction frame and the number of openings on the front of the display screen, increases the aesthetics of the front of the display screen, improves the user experience, and increases the convenience of disassembling the display screen.

[0014] As a preferred technical solution, the stepped hole is provided with a second pre-reserved section for easy-pull adhesive, which is connected to the easy-pull adhesive layer.

[0015] The stepped hole outlet is located on the side of the back cover. During the disassembly of the display screen, especially large displays, the display screen can be placed on a flat surface for disassembly. The second pre-reserved section of the easy-pull adhesive can be pulled out from the side, which increases the convenience of the disassembly personnel. Placing the display screen flat reduces the probability of damage to the display screen.

[0016] As a preferred technical solution, the pre-drilled hole for the easy-pull adhesive is a groove-shaped structure, with the groove located on the dispensing plane at the upper end of the back cover, and one side of the groove extending to the side of the back cover.

[0017] The groove is located on the easy-pull adhesive dispensing area on the upper surface of the back cover, and the side opening of the groove is located on the side of the back cover. After the display screen is packaged, the shielding frame covers the groove, and the groove opening is located on the side of the back cover, which ensures a smaller width of the shielding frame.

[0018] As a preferred technical solution, the groove is provided with a third pre-reserved section for easy-pull adhesive, which is connected to the easy-pull adhesive layer.

[0019] During the disassembly of the display screen, the recessed shielding frame is removed first, and then the third reserved section of the easy-pull adhesive is pulled out from the recess, which facilitates the disassembly work and improves disassembly efficiency.

[0020] As a preferred technical solution, the back cover is provided with a packaging platform, the easy-pull adhesive layer is disposed on the packaging platform, and the display screen assembly is bonded to the easy-pull adhesive layer.

[0021] The above technical solution facilitates the dispensing of adhesive tape by setting up an encapsulation platform, thereby increasing the efficiency of display screen encapsulation.

[0022] An electronic device includes the aforementioned display screen packaging structure.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] This utility model discloses a display screen packaging structure comprising a display screen assembly, an adhesive layer, and a back cover. The back cover has an adhesive pre-drilling hole. By placing the inlet and outlet of the adhesive pre-drilling hole on different planes, and providing an adhesive pre-drilling section within the hole, which is connected to the adhesive layer, this invention improves upon the problem in existing technologies where the adhesive pre-drilling section is located on the front of the display screen, resulting in a large width of the display screen obstruction frame. This significantly reduces the width of the front obstruction frame, increases the overall aesthetics of the display, and improves the ease of disassembly. Attached Figure Description

Detailed Implementation

[0034] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0035] Example 1:

[0036] like Figure 1-3 The diagram shown is a schematic diagram of the display screen packaging structure according to the first embodiment of this utility model.

[0037] The display screen encapsulation structure of this embodiment includes a display screen assembly 1, an easy-open adhesive layer 2, and a first back cover 31. The easy-open adhesive layer 2 is disposed between the display screen assembly 1 and the first back cover 31 for bonding and sealing the display screen assembly 1 and the first back cover 31. The first back cover 31 is provided with an encapsulation platform 4. When bonding the display screen assembly 1, easy-open adhesive is applied to the encapsulation platform 4, and then the display screen assembly 1 is placed on the easy-open adhesive on the encapsulation platform 4. After the easy-open adhesive cures, it forms the easy-open adhesive layer 2.

[0038] The encapsulation platform 4 has a through hole 311. The inlet of the through hole 311 is located on the bonding surface at the upper end of the encapsulation platform 4, and the outlet of the through hole 311 is located on the lower end surface of the first back cover 31. When applying adhesive, the adhesive enters the through hole 311. After the adhesive in the through hole 311 is cured, it forms the first reserved section 21 of the adhesive. The first reserved section 21 of the adhesive is connected to the adhesive layer 2 as an integral structure. When the display screen is disassembled for maintenance, the first reserved section 21 of the adhesive is pulled out from the outlet of the through hole 311 on the lower end surface of the first back cover 31. The adhesive layer 2 is pulled out along with the first reserved section 21 of the adhesive. After the adhesive layer 2 is pulled out to a certain length, the partial bonding relationship between the display assembly 1 and the first back cover 31 is released. Then, the adhesive layer 2 is pulled out from the separation point between the display assembly 1 and the first back cover 31 on the front side, which speeds up the extraction of the adhesive layer 2.

[0039] Example 2:

[0040] like Figure 4 and Figure 5 The diagram shown is a schematic diagram of the display screen packaging structure according to the second embodiment of this utility model.

[0041] The structure of the display assembly 1 and the easy-pull adhesive layer 2 in this embodiment is the same as that in Embodiment 1. The difference lies in the second back cover 32, which has a stepped hole 321. The opening of the stepped hole 321 is located on the encapsulation platform 4, and the outlet of the stepped hole 321 is located on the side of the second back cover 32. When applying easy-pull adhesive, the easy-pull adhesive enters through the stepped hole 321. After the easy-pull adhesive in the stepped hole 321 is cured, it forms the second reserved section 22 of easy-pull adhesive. The second reserved section 22 of easy-pull adhesive is connected to the easy-pull adhesive layer 2 as an integral structure. When the display is disassembled for maintenance, the second reserved section 22 of easy-pull adhesive is pulled out from the outlet of the stepped hole 321. The easy-pull adhesive layer 2 is pulled out along with the second reserved section 22 of easy-pull adhesive for the separation of the display assembly 1 and the second back cover 32.

[0042] Example 3:

[0043] like Figure 6-8 The diagram shown is a schematic diagram of the display screen packaging structure according to the third embodiment of this utility model.

[0044] The structure of the display assembly 1 and the easy-pull adhesive layer 2 in this embodiment is the same as that in Embodiment 1. The difference lies in the third back cover 33. A groove 331 is provided on the dispensing area of ​​the upper surface of the third back cover 33. One side of the groove 331 extends to the side of the third back cover 33. When the easy-pull adhesive is dispensed, the easy-pull adhesive enters into the groove 331. After the easy-pull adhesive in the groove 331 is cured, it forms the third reserved section 23 of the easy-pull adhesive. The third reserved section 23 of the easy-pull adhesive is connected to the easy-pull adhesive layer 2 as a whole. After the display is encapsulated, a shielding frame is installed on the upper end of the groove 331 for shielding. When the display assembly 1 is disassembled, the shielding frame is removed, and the third reserved section 23 of the easy-pull adhesive is pulled out. The easy-pull adhesive layer 2 is pulled out along with the third reserved section 23 of the easy-pull adhesive, realizing the disassembly of the display assembly 1 and the third back cover 33. The disassembly speed is fast and the operation is convenient.

[0045] In this utility model, the shape of the pre-drilled hole for the easy-open adhesive is not limited to a circle, an ellipse, a square, a rectangle or other irregular shapes. All of them are structures designed to ensure that the inlet and outlet of the pre-drilled hole for the easy-open adhesive are not on the same plane, and are all within the protection scope of this utility model.

[0046] The shape of the back cover 3 is not limited to irregular structures such as cubes, cuboids, cylinders, and trapezoidal truncated pyramids, all of which are within the protection scope of this utility model.
