Description

Technical Field

[0001] The utility model relates to the technical field of electronic product protection films, in particular to a protection film group for LCDs. Background Art

[0002] LCD modules are common electronic components. Since they are covered with polarizers on the top and bottom, protective films need to be attached to the polarizers when shipping to prevent the products from being scratched or dirty. Finally, manufacturers need to stack multiple LCD modules together and seal them for shipment in batches. The protective film in the prior art generally has an easy-to-tear handle, and the handle can be pulled to tear off the protective film during terminal production. However, the setting of the handle is not conducive to the shipment of LCD modules. Space needs to be reserved during plastic packaging, but the number of display screens that can be loaded in the same size of packaging blister is reduced, increasing the packaging cost. If space is not reserved during plastic packaging, the handle is easily squeezed, causing the protective film to warp, resulting in defective products.

[0003] For example, Chinese utility model patent CN208667575U proposes a protective film with an easy-tear handle, including a protective film, an easy-tear handle is provided at one corner of the protective film, the easy-tear handle is placed at the outer edge of the protective film, and the easy-tear handle and the protective film are integrally formed by punching; a folding indentation strip is pressed and formed between the easy-tear handle and the protective film, and the folding indentation strip coincides with the edge of one corner of the protective film and the edge of the easy-tear handle. The protective film proposed in this patent can be easily pulled up because the protective film and the easy-tear handle are integrally formed, but the applicant found when implementing this technical solution that when it is used for LCD module protective film, when multiple LCD modules need to be plastic-sealed for shipment, the handle position is easily squeezed and deformed, causing the protective film to warp, resulting in rework and affecting efficiency.

[0008] Furthermore, the distance between the side edge of the filling seal and the bonding edge of the glass substrate and the lower glass substrate is 0.5-1 mm.

[0009] Furthermore, the protective film group includes a first protective film and a second protective film, the first protective film covers the outer surface of the upper polarizer, and the second protective film covers the outer surface of the lower polarizer.

[0010] Furthermore, the protective film group also includes a first mucosa paper and a second mucosa paper, wherein the first mucosa paper partially covers the first protective film, the second mucosa paper partially covers the second mucosa paper, and the first mucosa paper and the second mucosa paper are symmetrically arranged in upper and lower positions.

[0011] Furthermore, it is characterized in that the hand-held structure is a first hand-held area and a second hand-held area.

[0012] Furthermore, the first adhesive film paper is provided with a first adhesive area and a first hand-holding area, and the boundary line between the first adhesive area and the first hand-holding area coincides with the side line of the first protective film.

[0013] Furthermore, the second adhesive film paper is provided with a second adhesive area and a second hand-holding area, and the boundary line between the second adhesive area and the second hand-holding area coincides with the side line of the second protective film.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0038] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0039] Example 1

[0040] Please refer to Figure 1-6 The utility model provides an LCD protection film group, which includes an LCD module and a protection film group. The protection film group is arranged on the surface of the LCD module to prevent the LCD module from being scratched or dirty during the process operation. Furthermore, the LCD module is provided with a binding position 13, and the binding position 13 is connected to the FPC or PCB board to form a conductive circuit.

[0041] Further, such as Figure 1 and 2 As shown, the LCD module includes an upper glass substrate 1, an upper polarizer 2, a lower glass substrate 5 and a lower polarizer 6. The upper glass substrate 1 and the lower glass substrate 5 are arranged in contact with each other, the upper polarizer 2 is placed on the upper glass substrate 1, and the lower polarizer 6 is placed under the lower glass substrate 2. Specifically, viewed from the side, the LCD module is composed of an upper polarizer 2, an upper glass substrate 1, a lower glass substrate 5 and a lower polarizer 6 in sequence.

[0042] Further, such as Figure 2 and 3 As shown, the length of the upper glass substrate 1 is greater than that of the lower glass substrate 5, the upper glass substrate 1 and the lower glass substrate 5 are attached to each other along the upper edge line, a driving IC 10 and a binding position 13 are provided at the bottom of the upper glass substrate 1, and liquid crystal materials are also provided inside the upper glass substrate 1 and the lower glass substrate 5. After the binding position 13 is connected to an external FPC or PCB board, the sorting state of the liquid crystal material is controlled by the driving IC to realize the display function of the LCD module.

[0043] Furthermore, if Figure 1 As shown, a filling seal 9 is further provided between the upper glass substrate 1 and the lower glass substrate 5. The filling seal 9 is provided on the left side or the right side adjacent to the bottom of the upper glass substrate 1. The filling seal 9 is extended along the bonding edge line of the upper glass substrate 1 and the lower glass substrate 5. Specifically, the filling seal 9 protrudes 0.5 to 1 mm along the bonding edge line of the upper glass substrate 1 and the lower glass substrate 5.

[0044] During installation, the upper glass substrate 1 and the lower glass substrate 5 that have completed circuit wiring and passed the inspection are aligned on the upper and left and right sides, laminated and hot-pressed, and then placed in a crystal filling machine to form a crystal filling port on the side adjacent to the driver IC of the upper glass substrate 1 to fill the liquid crystal. After the liquid crystal is filled, UV glue is applied to the crystal filling port and then cured by a UV lamp to form a filling seal 9; then the upper polarizer 2 is laminated on the upper glass substrate 1, and the lower polarizer 6 is laminated on the lower glass substrate 5 to complete the assembly of the LCD module.

[0045] The protective film group is symmetrically arranged on the upper and lower sides of the LCD module, and the protective film group is provided with a hand-held structure extending horizontally to the side. The hand-held structure is arranged on the same side as the filling seal 9, and the side lines of the hand-held structure and the filling seal 9 are flush.

[0046] Specifically, the protective film group is arranged on the outer surfaces of the upper polarizer 2 and the lower polarizer 6. Specifically, the protective film group includes a first protective film 3 and a second protective film 7. The first protective film 3 covers the outer surface of the upper polarizer 2, and the second protective film 7 covers the outer surface of the lower polarizer 6. The shape and size of the first protective film 3 are the same as those of the upper polarizer 2, and the shape and size of the second protective film 7 are the same as those of the lower polarizer 6.

[0047] Furthermore, the first protective film 3 has a weak adhesiveness on one side facing the upper polarizer 2, and a smooth and non-adhesiveness on the side facing away from the upper polarizer 2; the second protective film 7 has a weak adhesiveness on one side facing the lower polarizer 6, and a smooth and non-adhesiveness on the side facing away from the lower polarizer 6. Thus, the first protective film 3 and the second protective film 7 are respectively adhered to the surfaces of the upper polarizer 2 and the lower polarizer 6 to prevent the LCD module from being dirty and scratched during operation.

[0048] Furthermore, the protective film group also includes a first mucosa paper 4 and a second mucosa paper 8, wherein the first mucosa paper 4 partially covers the first protective film 3, the second mucosa paper 8 partially covers the second mucosa paper 8, and the first mucosa paper 4 and the second mucosa paper 8 are symmetrically arranged in upper and lower positions.

[0049] Further, such as Figure 4As shown, the first adhesive film paper 4 is provided with a first adhesive area 11 and a first hand-holding area 12, and the first adhesive area 11 and the first hand-holding area 12 are connected, and the boundary line between the first adhesive area 11 and the first hand-holding area 12 coincides with the side line of the first protective film 3, and the first adhesive area 11 is rectangular and is attached to the first protective film 3 along the top edge thereof, and the first hand-holding area 12 is formed by extending horizontally outward along the side line of the first protective film 3.

[0050] Similarly, if Figure 5 and 6 As shown, the second adhesive film paper 8 is provided with a second adhesive area 14 and a second hand-holding area 15, and the second adhesive area 14 and the second hand-holding area 15 are connected, and the boundary line between the second adhesive area 14 and the second hand-holding area 15 coincides with the side line of the second protective film 7, and the second adhesive area 14 is rectangular and is attached to the second protective film 7 along the top edge thereof, and the second hand-holding area 15 is formed by extending horizontally outward along the side line of the second protective film 7.

[0051] Among them, the adhesive surfaces of the first adhesive area 11 and the second adhesive area 14 are both highly adhesive. Through the structural setting of the first adhesive film paper 4 and the second adhesive film paper 8, the first protective film 3 and the second protective film 7 can be easily torn off by pulling the first hand-holding area 12 and the second hand-holding area 15 upwards. Therefore, the first hand-holding area 12 and the second hand-holding area 15 together constitute a hand-holding structure.

[0052] The first hand-holding area 12 and the second hand-holding area 15 are arranged on the same side as the filling and sealing opening 9 .

[0053] Furthermore, the side edges of the first hand-holding area 12 and the second hand-holding area 15 extend outward and protrude by 0.5 to 1 mm from the bonding edges of the upper glass substrate 1 and the lower glass substrate 5 .

[0054] Furthermore, the side lines of the first hand-held area 12 and the second hand-held area 15 are flush with the side lines of the filling seal 9. The bottom edges of the first hand-held area 12 and the second hand-held area 15 are flush with the bottom edges of the filling seal 9, and the top edges of the first hand-held area 12 and the second hand-held area 15 are flush with the top edges of the first protective film 3 and the second protective film 7, respectively. By arranging that the first hand-held area 12 and the second hand-held area 15 partially overlap with the filling seal 9 and the side lines are flush, the position of the hand-held structure and the filling seal 9 are integrated by utilizing the air-avoiding position that originally needs to be reserved for the filling seal 9 during packaging blister. There is no need to reserve a reserved position for the hand-held structure during packaging blister, and the hand-held structure will not warp after packaging blister. The same size of blister can be loaded with more display screens, reducing packaging costs.

[0055] During installation, take the assembled LCD module, place the first protective film 3 opposite to the upper polarizer 2 and adhere to the upper polarizer 2, and place the second protective film 7 opposite to the lower polarizer 6 and adhere to the lower polarizer 6; the first adhesive film paper 4 and the second adhesive film paper 8 are arranged in corresponding upper and lower positions, and the first hand-holding area 12 and the second hand-holding area 15 are arranged on the same side as the filling seal 9. Taking the filling seal 9 as an example, which is arranged on the left side of the LCD module, the top edge of the first adhesive film paper 4 is opposite to the top edge of the first protective film 3, and the boundary line of the first adhesive area 11 and the first hand-holding area 12 is opposite to the first protective film 3. The left side line of the film 3 is relatively fitted. At this time, according to the size design, the side line of the first hand-held area 12 is flush with the side line of the filling seal 9, and the bottom of the first hand-held area 12 is flush with the bottom of the filling seal 9; correspondingly, the top edge of the second adhesive film paper 8 is opposite to the top edge of the second protective film 7, and the boundary lines of the second adhesive area 14 and the second hand-held area 15 are relatively fitted with the side line of the second protective film 7. At this time, according to the size design, the side line of the second hand-held area 15 is flush with the side line of the filling seal 9, and the bottom of the second hand-held area 15 is flush with the bottom of the filling seal 9. Thus, the assembly is completed to form a sandwich structure of the first hand-held area 12, the filling seal 9 and the second hand-held area 15. This structure reduces the setting of the empty position of the packaging blister and reduces the packaging cost.
