Description

Technical Field

[0001] The utility model relates to the technical field of display modules, in particular to a narrow-bezel integrated touch module structure. Background Art

[0002] With the popularization of full-screen mobile phones, the requirement for the screen bezel is getting narrower and narrower, and the width of the light-shielding glue around the backlight is also correspondingly reduced, which makes it impossible to fix the display screen well. The current solution is to apply hot melt glue at the side to fix the display screen and the backlight with the glue, and at the same time, it also plays a role in light shielding. Patent application number 202221409978.X discloses a narrow-bezel integrated touch module structure using hot melt glue, which includes a touch module body and a mobile phone middle frame. The touch module body is arranged in the mobile phone middle frame. The touch module body includes a backlight and a LENS. The mobile phone middle frame includes a top edge and a side edge. A lower polarizer, a lower glass sheet, an upper glass sheet, and an upper polarizer are sequentially arranged between the backlight and the LENS. A first hot melt glue is filled between the side walls of the backlight, the lower polarizer, the lower glass sheet, the upper glass sheet, and the upper polarizer close to the top edge and the side wall of the top edge. Another example is patent application number CN202221708011.1, which discloses a narrow-bezel integrated touch module structure, which includes a LENS assembly. The LENS assembly includes a flat part, and a bent part is arranged on the side of the flat part. A touch display assembly is arranged at the bottom of the flat part. A second sealant is arranged between the side of the touch display assembly and the flat part. A middle frame assembly is arranged between the bent part and the bottom of the touch display assembly. Applying hot melt glue at the side, due to the flow characteristics of the glue, it is difficult to control the thickness of the glue after curing. If the glue amount is too thick, it will interfere with the installation of the end customer's machine, and the glue will also flow onto the iron frame on the back of the backlight, affecting subsequent disassembly and repair. Therefore, the utility model discloses a narrow-bezel integrated touch module structure to solve the above problems. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] As described in the background art, with the popularization of full-screen mobile phones, the requirements for the screen frame are getting narrower and narrower, and the width of the light-shielding glue around the backlight is also correspondingly reduced, making it impossible to fix the display screen well. The current solution is to apply hot melt glue at the side to fix the display screen and the backlight with the glue, and at the same time, it also plays a role in light shielding. When applying hot melt glue at the side, due to the fluidity characteristics of the glue, it is difficult to control the thickness of the glue after curing. If the glue amount is too thick, there will be interference when the end customer installs the machine, and the glue will also flow onto the iron frame on the back of the backlight, affecting subsequent disassembly and repair.

[0025] To solve this technical problem, the present utility model provides a narrow border integrated touch control module structure, which is applied to the field of display modules.

[0026] Specifically, please refer to Figures 1-3 , the narrow border integrated touch control module structure specifically includes a cover plate 1, a display module 2, a backlight module 3, an iron frame 4 and a glue holder 5. The iron frame 4 and the glue holder 5 are of an integral structure. The display module 2 is arranged on the back side of the cover plate 1. The backlight module 3 is arranged in the glue holder 5, and a light-shielding layer 6 is arranged between the backlight module 3 and the display module 2. An extension 7 is arranged on the outer side of the glue holder 5. A groove structure 8 is formed between the extension 7 and the cover plate 1. The groove structure 8 is filled with hot melt glue 10. The extension 7 is used to limit the hot melt glue 10, and the outer side wall of the hot melt glue 10 does not exceed the outer side wall of the iron frame 4.

[0027] The narrow border integrated touch control module structure provided by the present utility model forms an extension 7 by extending outward on the outer side of the glue holder 5. A groove structure 8 is formed between the extension 7 and the cover plate 1. The groove structure 8 serves as a glue application area, and the extension 7 can serve as a glue application limit point for the hot melt glue 10, facilitating the control of the glue application amount of the hot melt glue 10, preventing the glue amount from being excessive and exceeding the outer side of the iron frame 4, avoiding interference during terminal installation, and there will be no residual glue left on the iron frame 4, facilitating subsequent disassembly and repair. It is also easy to identify from the appearance whether the glue amount is excessive, facilitating the timely selection of modules with excessive glue amounts for rework.

[0028] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings.

[0029] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the present utility model can be combined with each other.

[0030] It should be noted that similar reference numerals and letters indicate similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0031] Please refer to Figures 1-3 , which provides a narrow bezel integrated touch module structure, which includes a cover plate 1, a display module 2, a backlight module 3, an iron frame 4 and a rubber frame 5. The iron frame 4 and the rubber frame 5 are of an integral structure. The display module 2 is arranged on the back side of the cover plate 1. The backlight module 3 is arranged in the rubber frame 5, and a light-shielding layer 6 is arranged between the backlight module 3 and the display module 2. The light-shielding layer 6 is a double-sided light-shielding adhesive tape, specifically a black adhesive layer. The light-shielding layer 6 is adhesively fixed on the rubber frame 5. An extension part 7 is arranged on the outer side of the rubber frame 5. A groove structure 8 is formed between the extension part 7 and the cover plate 1. And the side of the iron frame 4 is bent upward, and the bent part 9 is flush with the inner wall of the groove structure 8 of the extension part 7. The groove structure 8 is filled with hot melt adhesive 10. The hot melt adhesive 10 is black hot melt adhesive, which plays a side light-shielding effect. The upper part of the hot melt adhesive 10 is adhesively bonded to the cover plate 1, and the inner side wall is adhesively bonded to the side of the display module 2. At the same time, the lower part of the double-sided light-shielding adhesive tape is adhesively bonded to the rubber frame 5, and at the same time, the connection part between the iron frame 4 and the rubber frame 5 can be sealed. The extension part 7 is used to limit the hot melt adhesive 10, and the outer side wall of the hot melt adhesive 10 does not exceed the outer side wall of the iron frame 4, so as to avoid excessive dispensing of the hot melt adhesive 10, and also to avoid the adhesion of the hot melt adhesive 10 to the side wall of the iron frame 4, preventing the glue from flowing to the side of the iron frame. If the amount of glue is higher than the surface of the iron frame 4, it means that the amount of glue is excessive. If it is higher than the surface of the iron frame 4, it is also easy to be recognized visually and can be picked out for rework in time to avoid reaching the end customer and affecting the installation and use.

[0032] The cover plate 1 is a glass plate. The cover plate 1 is divided into a display area 101 and a non-display area 102. A layer of black ink 11 is screen-printed on the back side of the cover plate 1 in the non-display area 102, which plays a light-shielding role.

[0033] The narrow bezel integrated touch module structure provided in Embodiment 1 is further optimized. Specifically, as Figure 1 shown, the display module 2 includes a polarizer 201, an upper glass sheet 202, a lower glass sheet 203 and a polarizer 204 which are sequentially stacked. The polarizer 201 is adhesively fixed to the back side of the cover plate 1 through an optical adhesive 205. The optical adhesive 205 is a transparent adhesive. The sides of the polarizer 201, the upper glass sheet 202, the lower glass sheet 203, the polarizer 204 and the light-shielding layer 6 are flush, and are on the same side as the outer side surface of the iron frame 4. The sides of the display module 2 and the light-shielding layer 6 are located at the bottom of the groove structure 8. The hot melt adhesive 10 seals the sides of each layer of the display module 2.

[0034] The narrow-bezel integrated touch module structure provided in Embodiment 2 is further optimized. Specifically, as Figure 1 shown, the backlight module 3 includes a light guide plate 301, a diffusion film 302, a lower brightness enhancement film 303, and an upper brightness enhancement film 304 stacked in sequence from bottom to top. The light-shielding layer 6 is attached to the upper brightness enhancement film 304. The light-shielding layer 6 is a frame structure, and the light-shielding layer 6 shields the four sides of the upper brightness enhancement film 304 to avoid light scattering to the surroundings. Moreover, the sides of the diffusion film 302, the lower brightness enhancement film 303, and the upper brightness enhancement film 304 are flush. A reflective film 305 is provided on the bottom surface of the light guide plate 301, and the reflective film 305 is attached to the iron frame 4 to reduce light loss and improve light brightness. A light source is also provided between the light guide plate 301 and the rubber holder 5 to provide the backlight for the backlight module 3. After the light emitted by the light source is evenly scattered from the light guide plate 301 and passes through two layers of brightness enhancement films, the diffusion film 302 further diffuses the light, so that the light is evenly scattered onto the display module 2.

[0035] The working principle of the narrow-bezel integrated touch module structure provided by the present utility model: The backlight module 3 is installed in the rubber holder 5, the display module 2 is bonded and fixed to the cover plate 1, the light-shielding layer 6 is bonded to the surface of the backlight module 3, and the light-shielding layer 6 is bonded to the display module 2. One end of the light-shielding layer 6 is aligned with the ends of the upper polarizer 201, the upper glass sheet 202, the lower glass sheet 203, and the lower polarizer 204. The dispensing mechanism dispenses the hot melt adhesive 10 into the groove structure 8, and the extension portion 7 on the rubber holder 5 serves as the dispensing limit point for the hot melt adhesive 10, which is convenient for controlling the dispensing amount of the hot melt adhesive 10, preventing the amount of adhesive from being too much and exceeding the outside of the iron frame 4, avoiding interference during terminal installation, and there will be no residual adhesive left on the iron frame 4, which is convenient for subsequent disassembly and repair, and it is also possible to easily identify from the appearance whether the amount of adhesive is too much, facilitating the timely selection of modules with excessive adhesive amount for rework.
