Display touch film fixing structure and method

Abstract

The application discloses a display touch film fixing structure and method, which comprises a touch module film and a liquid crystal module. The periphery of the touch module film is provided with a plurality of upwardly folded extension fins. The back edge of the liquid crystal module is respectively provided with a detachable fixing support corresponding to each extension fin. The side of the fixing support towards the center of the liquid crystal module is provided with a through hole. The top of the fixing support is pasted with a pre-fixed double-sided adhesive tape. The extension fins are pulled straight and tight after passing through the through hole of the fixing support. The extension fins are pre-fixed with the pre-fixed double-sided adhesive tape, and then are fixed by UV glue solidification connection between the extension fins and the fixing support. The extension fins of the touch module film are fixed by the fixing support, and the through hole on the fixing support can effectively pull the extension fins of the touch module film tight. Meanwhile, the extension fins of the touch module film are fixed by UV glue, which is stronger than the double-sided adhesive tape in adhesive force, and the fixing is more reliable and stable.

Description

Technical Field

[0001] This invention relates to the field of touch display technology, and in particular to a display touch film fixing structure and method. Background Technology

[0002] With the rapid development of technology, touch displays have become widely used in various fields, and their specifications are largely similar. In addition to price and specifications, appearance is also one of the key factors for consumers. Narrow bezel design has become the mainstream design pursued by major brands. However, the reduction of the bezel will also reduce the space for the touch cover and the panel to fit together, and increase the risk of the touch screen falling off.

[0003] Large touchscreens typically have a glass cover, and the narrow bezel design requires a certain amount of adhesive area to secure the cover and support its weight. Current designs address this by folding the touch module film along the panel's shape and attaching it to the back of the LCD module with double-sided tape, or by attaching the film itself with adhesive to the back of the LCD module, or by attaching it to the side of the mid-frame. These technologies involve directly attaching the touch extension film to the LCD module or mid-frame. However, this method is inconvenient for later repairs and results in material loss during the repair process. Furthermore, assembly personnel cannot tighten the film in a fixed position, preventing the extension film from effectively covering the LCD module. This can lead to a larger gap between the cover and the mid-frame, resulting in visible assembly gaps and even cover detachment. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention aims to provide a display touch film fixing structure and method, so that the fixing strength between the touch module and the panel is not limited by the space of the narrow bezel, and can effectively increase the adhesive area and facilitate disassembly and rework.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A display touch film fixing structure includes a touch module film and a liquid crystal module. The touch module film covers the display surface of the liquid crystal module, and the periphery of the touch module film is provided with multiple upwardly folded extension fins. A detachable fixing bracket is fixed to the back edge of the liquid crystal module corresponding to each extension fin. The fixing bracket has a through hole on its side facing the center of the liquid crystal module. Pre-fixing double-sided adhesive is pasted on the top of the fixing bracket. The extension fins pass through the through holes on the fixing bracket and are pulled straight and tightened upward. The extension fins are pre-fixed to the pre-fixing double-sided adhesive and then fixed by UV adhesive between the extension fins and the fixing bracket.

[0006] Furthermore, the mounting bracket is fixed to the back edge of the LCD module by screws.

[0007] Furthermore, the top of the fixing bracket has a dispensing groove, and UV adhesive is placed in the dispensing groove.

[0008] Furthermore, the extended fins are provided with two or more holes spaced apart at the positions corresponding to the glue dispensing grooves.

[0009] The fixing method using the above-mentioned display touch film fixing structure includes the following steps: 1) Assemble the LCD module and the touch module film, with each extended fin of the touch module film folded upwards; 2) Fix each bracket to the corresponding extended fin on the back edge of the LCD module, and attach pre-fixed double-sided tape to the top surface of each bracket. 3) Apply UV adhesive to the dispensing groove at the top of each fixed bracket; 4) Pass each extension fin through the hole on the corresponding fixing bracket and pull the free end of the extension fin outward at 90°. At the same time, attach the extension fin to the corresponding fixing bracket with double-sided adhesive tape. 5) Irradiate the UV adhesive on each mounting bracket with UV light until the UV adhesive cures (irradiation time is 10-15 seconds); 6) Cut off the excess portion at the free end of the extended fins.

[0010] The present invention adopts the above technical solution and has the following beneficial technical effects: 1. A fixing bracket is used to fix the extended fins of the touch module film. The fixing bracket has perforations, which can effectively tighten the extended fins of the touch module film. 2. The extended fins of the touch module film are fixed with UV adhesive, which has stronger adhesion and more reliable and stable fixation than double-sided tape; 3. This architecture allows the LCD module and touch module to be removed simply by unscrewing the screws, without any wear and tear issues. Attached Figure Description

Detailed Implementation

[0012] like Figure 1-8 As shown, the present invention discloses a display touch film fixing structure, including a touch module film 1 and a liquid crystal module 2. The touch module film 1 covers the display surface of the liquid crystal module 2, and the periphery of the touch module film 1 is provided with a plurality of upwardly folded extension fins 11. A detachable fixing bracket 3 is fixed on the back edge of the liquid crystal module 2 corresponding to each extension fin 11. The fixing bracket 3 has a through hole on the side facing the center of the liquid crystal module 2. A pre-fixing double-sided adhesive 4 is pasted on the top of the fixing bracket 3. After the extension fins 11 pass through the through holes on the fixing bracket 3, they are pulled straight and tightened upward. The extension fins 11 and the pre-fixing double-sided adhesive 4 are pre-fixed first, and then the UV adhesive 6 between the extension fins 11 and the fixing bracket 3 is cured and fixed.

[0013] Furthermore, the mounting bracket 3 is fixed to the back edge of the LCD module 2 by screws.

[0014] Furthermore, the top of the fixing bracket 3 has a dispensing groove, and UV adhesive 6 is placed in the dispensing groove.

[0015] The extended fins 11 of this invention are fixed to the fixing bracket 3 with UV adhesive 6, and the adhesion force can reach 4-8 kg or more. Figure 2 As shown, if two or more holes 111 are designed at intervals at the position of the adhesive groove corresponding to the extended fin 11, when combined with the fixed bracket 3, the UV adhesive will overflow from the holes 111. After being irradiated with UV adhesive 6 and cured, a snap-fit ​​structure will be formed, which can enhance the bonding strength by more than double.

[0016] The fixing method of the present invention includes the following steps: 1) Assemble the liquid crystal module 2 and the touch module film 1, and fold each of the extended fins 11 of the touch module film 1 upwards; 2) Fix each fixed bracket 3 to the back edge of each extended fin 11 respectively, and attach pre-fixed double-sided tape 4 to the top surface of each fixed bracket 3. 3) Apply UV glue 6 to the glue groove at the top of each fixed bracket 3; 4) Pass each extension fin 11 through the hole on the corresponding fixing bracket 3 and pull the free end of the extension fin 11 outward at 90°. At the same time, attach the extension fin 11 to the corresponding fixing bracket 3 with the pre-fixed double-sided tape 4. 5) Irradiate the UV adhesive 6 on each fixing bracket 3 with UV light until the UV adhesive 6 cures (irradiation time is 10-15 seconds); 6) Cut off the excess portion at the free end of the extended fin 11.
