Description

Technical Field

[0001] The utility model belongs to the technical field of glass diffusion plates, and particularly relates to a structure for preventing glue overflow in the frame glue bonding of a glass diffusion plate. Background Art

[0002] For a borderless direct-lit backlight module, the connection method between the light homogenizing component diffusion plate and the module support frame is usually frame bonding and fixing. To ensure the connection strength between the diffusion plate and the support frame without expanding the ineffective area of the diffusion plate, a frame adhesive with a narrow width and high viscosity needs to be selected for frame bonding. Especially for a diffusion plate made of glass, due to the large mass of the glass, a tape with stronger adhesion is required to bond firmly. Conventional solid tapes cannot meet the viscosity requirements. As one of the most firmly bonding glues for glass, liquid invisible glue is often used to bond the glass diffusion plate and the backlight support frame. However, during the frame bonding process of the liquid glue, due to its strong fluidity, glue overflow is likely to occur. When the glue overflows to the light-emitting area of the diffusion plate, it will cause shadows and affect the display picture effect. When the glue overflows onto the support frame, wiping will bring labor and time costs, and it is not easy to remove the glue after curing as it adheres firmly. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a structure for preventing glue overflow in the frame glue bonding of a glass diffusion plate, so as to solve the technical problem of easy glue overflow, which will cause shadows and affect the display picture effect when the glue overflows to the light-emitting area of the diffusion plate, and achieve the purpose of preventing glue overflow and improving product quality.

[0007] Grooves are opened at both ends of the backlight module support frame, and a UV invisible glue layer is arranged in the grooves;

[0008] A fully bonded glass diffusion plate structure is arranged on the backlight module support frame. The glass diffusion plate structure includes a glass substrate, a lower diffusion coating on the light incident surface, an upper diffusion coating on the light exit surface, an OCA optical adhesive, and an optical film layer; the optical film layer is arranged on the outer side of the upper diffusion coating, and the OCA optical adhesive is arranged between the upper diffusion coating and the optical film layer.

[0009] Further, the width of both ends of the backlight module support frame is 2.5 - 3 mm.

[0010] Furthermore, the groove width is 1.5 mm and the groove depth is 0.5 mm.

[0022] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figure 1As shown in the figure, a structure for preventing glue overflow in the bonding of a glass diffusion plate frame includes a backlight module support frame 1. The backlight module support frame 1 is in a U shape, and a number of LED beads 11 are arranged in the backlight module.

[0025] Among them, grooves 2 are provided at both ends of the backlight module support frame 1, and a UV shadowless glue layer 3 is arranged in the grooves 2. The width of both ends of the backlight module support frame 1 is 2.5 - 3 mm, the width of the groove 2 is 1.5 mm, and the depth of the groove 2 is 0.5 mm.

[0026] A fully bonded glass diffusion plate structure 4 is arranged on the backlight module support frame 1. The glass diffusion plate structure 4 includes a glass substrate 41, a lower diffusion coating 42 on the light incident surface, an upper diffusion coating 43 on the light exit surface, an OCA optical adhesive 44, and an optical film layer 45. The optical film layer 44 is arranged on the outer side of the upper diffusion coating 43, and the OCA optical adhesive 44 is arranged between the upper diffusion coating 43 and the optical film layer 45. An OCA glue layer 45 is arranged between the upper diffusion coating 43 and the optical film 44 to improve the connection stability between the upper diffusion coating 43 and the optical film 44.

[0027] In this embodiment, after the UV shadowless glue layer 3 is placed in the groove 2, a UV curing lamp 5 is arranged beside the backlight module support frame 1. The UV curing lamp 5 irradiates at an angle of 45 degrees, and the light enters from the glass substrate 41, so that the four sides of the lower diffusion coating 4 all shrink inwards, and the shrinkage width is the same as the width of the backlight module support frame 1, ensuring that the glue in the groove 2 can directly contact the glass substrate 41, improving the bonding force. The four end faces of the glass substrate 41 are treated with light edges, so that the UV light enters from the end faces to complete the curing of the UV shadowless glue.

[0028] In summary, by designing the groove 2 on the support frame of the backlight module and injecting liquid glue into the groove, the purpose of preventing glue overflow is achieved.
