Description

Technical Field

[0001] This utility model relates to the field of display module packaging, and in particular to an edge-wrapping adhesive structure for display modules. Background Technology

[0002] The edge-sealing adhesive for display modules is a key material used to fix and protect the edges of the display screen, and can prevent light leakage or reflection. It is commonly used in the encapsulation of display modules such as LCD and OLED.

[0003] Currently, most display module edge-wrapping adhesive structures are arranged according to the required shape of the Mylar adhesive, with a release liner underneath. When arranging the adhesive, a gap of 1-2mm needs to be reserved between adjacent Mylar adhesive pieces. The release liner requires a large area, resulting in high costs. During operation, individual pieces of Mylar adhesive are torn off by hand or tweezers, aligned with the edges and left and right positions of the display module, and then folded and wrapped. Because the Mylar adhesive is thin, soft, and lacks support, it is easy to deform and wrinkle when torn off, making the application difficult and resulting in low yield and low production efficiency. Utility Model Content

[0004] To address the shortcomings or defects of the existing technology, this utility model provides an edge-wrapping adhesive structure for display modules, which can reduce costs, prevent hands or tweezers from contacting the adhesive surface during application, make it easier to apply Mylar adhesive to the front of the display module, and provide release film support at the bottom of the Mylar adhesive when applying it to the front of the display module, making it less prone to deformation, wrinkles, and lifting, thereby increasing the production efficiency and yield of display modules.

[0005] The technical solution is as follows: A display module edge-binding adhesive structure includes a bottom release film assembly sheet, which is composed of several release films. A Mylar adhesive is adhered to two adjacent release films. The length of the bottom release film assembly sheet is greater than the length of the several Mylar adhesives. The several Mylar adhesives are arranged side by side, and the edges of two adjacent Mylar adhesives are in close contact. Each of the several Mylar adhesives is provided with a front attachment portion and a back attachment portion.

[0006] Preferably, the bottom release film assembly is made of rigid PET material.

[0007] Preferably, the position where the front attachment portion contacts the back attachment portion is 0.2 mm away from the two adjacent release film seams.

[0008] Preferably, the Mylar adhesive has a thickness of 0.03 mm and is made of a light-shielding material.

[0009] Preferably, the two ends of the Mylar adhesive are 5 mm apart from the two ends of the bottom release film assembly sheet.

[0010] Preferably, the width of the front attachment portion is the width required to be attached to the front of the display module, and the width of the back attachment portion is the sum of the widths required to be attached to the sides and back of the display module.

[0011] The beneficial effects of this utility model are as follows: The worker peels off the first release film, separating it from the first Mylar adhesive. The separated portion of the Mylar adhesive is aligned with the front of the display module to be attached. After attaching the front, it is pressed. Then, the second release film is peeled off downwards, separating the first Mylar adhesive from the bottom release film assembly. The worker then picks up the display module with the first Mylar adhesive attached and bends and presses it against the worktable, ensuring the back attachment is tightly against the sides and back of the display module. The peeled-off second release film separates the second Mylar adhesive from the second release film. Thus, by setting the Mylar adhesive to continuous, gapless layout, the area of ​​the release film is saved, resulting in lower costs. Furthermore, when attaching the front of the display module, the release film supports the bottom of the Mylar adhesive, preventing the worker's hands or tweezers from contacting the adhesive surface, reducing deformation, wrinkles, and lifting. This leads to higher production efficiency and a higher yield rate for the display modules. Attached Figure Description

[0017] The following description is only a preferred embodiment of the present invention and does not limit the scope of protection of the present invention.

[0018] Example 1 An edge-wrapping adhesive structure for a display module, such as Figures 1-4As shown, it includes a bottom release film assembly sheet 1, which is composed of a plurality of release films 11. A Mylar adhesive 2 is adhered to two adjacent release films 1. The length of the bottom release film assembly sheet 1 is greater than the length of the plurality of Mylar adhesives 2. The plurality of Mylar adhesives 2 are arranged side by side, and the edges of two adjacent Mylar adhesives 2 are in close contact. Each of the plurality of Mylar adhesives 2 is provided with a front attachment portion 21 and a back attachment portion 22.

[0019] The bottom release film assembly 1 is made of rigid PET material.

[0020] The position where the front attachment portion 21 contacts the back attachment portion 22 is 0.2 mm away from the seam of the two adjacent release films 11.

[0021] The thickness of the Mylar adhesive 2 is 0.03mm, and the Mylar adhesive 2 is made of a light-shielding material.

[0022] The two ends of the Mylar adhesive 2 are 5 mm apart from the two ends of the bottom release film assembly 1.

[0023] The width of the front attachment portion 21 is the width required to be attached to the front of the display module, and the width of the back attachment portion 22 is the sum of the widths required to be attached to the sides and back of the display module.

[0024] In use, the display module requiring edge binding is placed on the worktable. The worker peels off the first release film 11, separating it from the first Mylar adhesive 2. The part of the first Mylar adhesive 2 that is separated from the first release film 11 is aligned with the front of the display module to be attached. After attaching the front side, it is pressed. Then, the second release film 11 is peeled off downwards, separating the first Mylar adhesive 2 from the bottom release film assembly 1. The worker then picks up the display module with the first Mylar adhesive 2 attached and bends and presses the first Mylar adhesive 2 against the worktable to ensure proper backing. Part 22 is closely attached to the sides and back of the display module. The second release film 11 is peeled off so that the second Mylar adhesive 2 is just separated from the second release film 11. Then, the same operation is performed on the other three sides of the display module. In this way, by setting the Mylar adhesive 2 to be continuously arranged without gaps, the area of ​​the release film 11 can be saved, thereby reducing the cost. Moreover, when attaching the front of the display module, the Mylar adhesive 2 is supported by the release film 11 at the bottom, so that the worker's hand or tweezers will not come into contact with the adhesive surface during attachment, making it less prone to deformation, wrinkles and lifting, thereby increasing the production efficiency and yield of the display module.
