Technical Field

[0001] The utility model relates to the technical field of in-vehicle display devices, and particularly relates to an ultra-narrow bezel display screen structure. Background Art

[0002] Currently, the peripheral panel bezel of in-vehicle display screens is wide. The smaller the bezel width of the panel, the higher the proportion of the display area, and the better the visual experience. While continuously increasing the proportion of the display area, it has also become the mainstream trend in the development of in-vehicle display screens to reduce the overall thickness of the display screen.

[0003] Existing narrow bezel display screens generally include a display module, a front panel, a front frame, a rear shell, and screws. As Figure 1 shown, the display module and the front panel are bonded by double-sided tape + RTV glue. Then, the front frame and the front panel are snap-fitted and connected, and assembled by screwing. As shown in the appendix Figure 2 shown, the rear shell and the front panel are also assembled by snap-fitting and screwing. As shown in the appendix Figure 3 shown, this assembly method has high requirements for the dimensional accuracy and consistency of the snaps, and has low assembly efficiency. Disassembly is cumbersome and easily damages parts. In addition, the front frame is wrapped in the middle by the front shell and the rear shell, and the thickness of the parts is stacked. Also, the screwing space between the front frame and the panel needs to be ensured, resulting in the inability to further reduce the thickness of the display screen. Content of the Utility Model

[0005] The purpose of the utility model is realized as follows: An ultra-narrow bezel display screen structure includes a display module and a front panel arranged at the rear end of the display module. A front frame is arranged at the rear end of the front panel. The front panel includes a bezel. A boss is arranged at the bottom of the bezel. An outer glue application area is arranged on the boss. Structural glue is applied in the outer glue application area to bond and fix the boss and the CG glass of the display module. A display module backlight is arranged on the side of the display module facing the front panel. An inner glue application area is arranged in the inner circle of the outer glue application area corresponding to the display module backlight. A notch is opened in the middle of the front panel. The front frame is installed at the notch, and the front frame and the display module backlight are locked and fixed by screws.

[0006] When the utility model works, the front panel and the display module are bonded by structural adhesive, and screws are used to lock and fix in the area where no adhesive is applied in the middle of the front panel. The front frame and the backlight of the display module are locked and fixed with screws. The thickness of the frame can be reduced to 1.6 mm, achieving an ultra-narrow frame, reducing the number of internal parts, reducing the assembly process, and improving the assembly efficiency.

Specific implementation mode

[0024] Such as Figures 4 to 7 shown, a super-narrow bezel display screen structure includes a display module 1, a front panel 3 arranged at the rear end of the display module 1, a front frame 4 is arranged at the rear end of the front panel 3, the front panel 3 includes a frame 13, a boss 14 is arranged at the bottom of the frame 13, an outer gluing area 11 is arranged on the boss 14, and a structural adhesive 8 is applied in the outer gluing area 11 to bond and fix the boss 14 and the CG glass of the display module 1; a display module backlight is arranged on the side of the display module 1 facing the front panel 3, and an inner gluing area 12 is arranged in the inner circle of the outer gluing area 11 corresponding to the display module backlight, a notch is opened in the middle of the front panel 3, the front frame 4 is installed at the notch, and the front frame 4 is locked and fixed with the display module backlight through screws.

[0025] The thickness of the frame 13 does not exceed 1.6 mm.

[0026] The display module backlight is made of die-cast aluminum, and the die-cast aluminum structure increases the overall structural strength of the display module 1.

[0027] Structural adhesives 8 are applied on both the outer gluing area 11 and the inner gluing area 12, and the structural adhesive 8 is a PUR structural adhesive.

[0028] When the utility model works, an external glue application area 11 is arranged on the boss 14 at the bottom of the frame 13 of the front panel 3. The external glue application area 11 corresponds to the CG glass of the display module 1. A display module backlight is arranged on the side of the display module 1 facing the front panel 3. Correspondingly, an internal glue application area 12 is arranged in the inner circle of the external glue application area 11. The PUR structural glue is coated on the external glue application area 11 and the internal glue application area 12 by a glue applicator, so that the boss 14 is adhesively fixed to the CG glass of the display module 1, and the display module backlight is adhesively fixed to the front panel 3. Since the structural glue has very strong adhesive force, very good durability and toughness, it can ensure that the ultra-narrow frame 13 of the front panel 3 is uniformly stressed and firmly fixed without deformation, which is beneficial to controlling the uniformity of the gap between the front panel 3 and the CG glass. The structural glue can quickly provide a gripping force during the bonding process, and with the passage of time, the bonding strength is further enhanced. The area in the middle of the front panel 3 where no glue is applied is locked and fixed with screws to further improve the overall structural strength. In the utility model, a notch is arranged in the middle of the front panel 3, and the front frame 4 is correspondingly installed at the notch, and the front frame 4 is locked and fixed to the display module backlight with screws. Compared with the prior art in which the front frame 4 and the front panel 3 are connected by snap-fastening (see Figures 1 to 3 ), the front frame 4 in this device is more miniaturized, simplified and lightweight, and the disassembly of the front frame 4 is no longer restricted by other components, and the disassembly and assembly are more flexible and simple, improving the assembly efficiency, and the overall thickness of the display screen is also significantly reduced.

[0029] When assembling the ultra-narrow frame display screen of this device, first place the front panel 3 on an automatic glue application workbench for automatic glue application. According to the glue application track on the front panel 3, set the glue application route of the glue applicator, assemble the glued front panel 3 with the backlight module 1, and use a pressing tooling for pressing. Set the pressing time according to the glue curing time. After the glue is cured and the front panel and the backlight module are well bonded, lock the panel screws at the automatic screw-locking station, and finally lock and fix the front frame 4 to the display module 1 with screws to complete the assembly of the entire display screen.

[0030] Through the display screen structure design of the utility model, there is no longer an assembly relationship between the front panel, the front frame and the rear shell, making the assembly relationship simpler. The bonding method is mainly used between the front panel and the display module, and screws are used as an auxiliary for locking. The amount of screws used can be reduced by half, reducing the production cost. This device realizes the ultra-narrow frame width of the front panel, improves the display area ratio, and provides a better visual experience effect for users. This device places the front frame externally, and the snap-fastening for the front frame assembly is cancelled, reducing the assembly difficulty and improving the assembly efficiency. The snap-fastening assembly inside the display screen is cancelled, making the internal structure more compact, reducing the overall thickness of the display screen, achieving the overall ultra-thin effect, and being more lightweight as a whole, and being suitable for use in the installation of in-vehicle display screens.

[0031] The present utility model is not limited to the above embodiments. Based on the technical solutions disclosed by the present utility model, those skilled in the art can make some substitutions and deformations to some of the technical features without creative labor according to the disclosed technical content, and these substitutions and deformations are all within the protection scope of the present utility model.
