Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a double-sided adhesive release film structure of a display module. Background Art

[0002] Liquid crystal display devices are widely used in various information, communication and consumer electronic products. In vehicles, the application of liquid crystal display modules is also common. Liquid crystal display modules are mainly composed of a liquid crystal display screen and a backlight module.

[0003] When the display module in the prior art is connected to the client shell, RTV glue and double-sided adhesive are used for pasting and fixing, and there is contact between the RTV glue and the double-sided adhesive. Since the viscosity of RTV glue is relatively high, it is necessary to stop dispensing glue when avoiding the double-sided adhesive, and tear off the release film on the double-sided adhesive before applying RTV glue. When the RTV glue is applied and stops at the double-sided adhesive, the needle will pull the glue, causing the RTV glue to be drawn onto the double-sided adhesive, thereby affecting the viscosity of the double-sided adhesive. If the release film of the double-sided adhesive is torn off after applying RTV glue, the release film will take away some RTV glue, resulting in a lack of glue, making the connection between the display module and the client shell unstable.

The RTV glue 30 has multiple sections, and the multiple sections of the RTV glue 30 are distributed along the outer circumferential direction of the display module body 10. The multiple sections of the RTV glue 30 are located between the display module body 10 and the client shell 20, and are used for bonding and fixing between the display module body 10 and the client shell 20. The dispensing thickness of the RTV glue 30 is 0.8 mm.

[0026] Reference Figure 1 A double-sided adhesive 40 for bonding and fixing is also provided between the display module body 10 and the client shell 20. The double-sided adhesive 40 has multiple sections, and the multiple sections of double-sided adhesive 40 are distributed along the outer circumferential direction of the display module body 10. A section of double-sided adhesive 40 is provided between two adjacent sections of RTV adhesive 30, and the multiple sections of double-sided adhesive 40 are respectively provided between two adjacent sections of RTV adhesive 30.

Multiple sections of the RTV glue 30 and multiple sections of the double-sided adhesive 40 are disposed between the display module body 10 and the client shell 20 to ensure the connectivity between the two.

[0028] Reference Figure 2 and Figure 3Two release films are arranged on the double-sided adhesive tape 40, and the two release films are respectively a first release film 50 and a second release film 60. The double-sided adhesive tape 40 is arranged in a rectangular shape, and the size of the first release film 50 is larger than the size of the double-sided adhesive tape 40. The first release film 50 is arranged in a U-shaped shape, and the length of the first release film 50 is adapted to the length of the double-sided adhesive tape 40. The three adjacent outer edges of the first release film 50 are respectively flush with the three adjacent outer edges of the double-sided adhesive tape 40.

[0029] Further, refer to Figure 2 The two sides of the first release film 50 respectively cover the two side edges of the double-sided adhesive 40 by 1-2 mm.

[0030] Reference Figure 2 and Figure 3 , the second release film 60 is located inside the first release film 50, the second release film 60 is arranged in a rectangular shape, the second release film 60 covers the area except the coverage of the first release film 50, the second release film 60 covers the middle area of ​​the double-sided adhesive 40, and the first release film 50 and the second release film 60 jointly cover the entire area of ​​the double-sided adhesive 40. Before dispensing the RTV glue 30, the first release film 50 is torn off to expose 1-2 mm of the outer edge of the double-sided adhesive 40, and then the RTV glue 30 is dispensed.
