Description

Novel framework backlight module

Technical Field

The utility model relates to the technical field of backlight source production and manufacturing, in particular to a novel-framework backlight module.

Background

At present, the backlight framework mainly comprises a rubber frame, a back plate, a reflector plate, an LGP, an led and a membrane, wherein the membrane comprises a diffusion sheet, a brightness enhancement film BEF composite membrane and the like.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned drawbacks of the prior art, the present invention provides a backlight module with a novel structure, which is characterized in that a reflective coating is added on the lower surface of an LGP, and reflective particles are directly coated on the lower surface of the LGP, so that the LGP and the LGP are integrated into a whole and have the functions of the original LGP and a reflector, and the use of the two-in-one LGP can effectively reduce the labor cost and the defects of white spots and the like caused by foreign matters in the operation process.

The purpose of the utility model can be realized by the following technical scheme:

the utility model provides a novel framework backlight unit, includes the backplate, and the inside of backplate has set gradually LGP and diaphragm framework from inside to outside, and the internal surface of backplate lateral wall is provided with the LED light source, and LGP has relative bottom surface and goes out the plain noodles, and one side that LGP is close to the diaphragm framework is for going out the plain noodles, and LGP's bottom surface is provided with reflective coating, and reflective coating is used for replacing the reflector plate in traditional backlight framework.

Further preferably, a tin foil is disposed between the LGP layer and the back plate, and an area of the tin foil is larger than an area of the bottom surface of the LGP.

Further preferably, a hot melt adhesive film is disposed between the LGP and the tin foil sheet.

Further preferably, the hot melt adhesive film connects the LGP and the tin foil sheet through a hot melt process.

Further preferably, still include the plastic part, the backplate passes through the plastic part and constructs spacing fixed to the diaphragm.

The utility model has the beneficial effects that:

the utility model adds the reflective coating on the lower surface of the LGP, and the reflective particles are directly coated on the lower surface of the LGP, so that the LGP and the lower surface of the LGP are combined into a whole and have the functions of the original LGP and the reflector plate, and the two-in-one LGP can effectively reduce the labor cost and the defects of foreign matter white spots and the like caused in the operation process.

Drawings

The utility model will be further described with reference to the accompanying drawings.

FIG. 1 is a cross-sectional view of the overall construction of the present invention;

fig. 2 is a structural sectional view of an LGP in the present invention.

In the figure:

1. a back plate; 2. an LGP; 3. a membrane architecture; 4. an LED light source; 5. a reflective coating; 6. a tin foil sheet; 7. hot-melt adhesive films; 8. a plastic component.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "opening," "upper," "lower," "thickness," "top," "middle," "length," "inner," "peripheral," and the like are used in an orientation or positional relationship merely to facilitate description of the utility model and to simplify the description, and are not intended to indicate or imply that the referenced components or elements must be in a particular orientation, constructed and operative in a particular orientation, and are not to be construed as limiting the utility model.

As shown in fig. 1-2, a novel-structure backlight module includes a back plate 1, an LGP2 and a film frame 3 are sequentially disposed inside the back plate 1 from inside to outside, an LED light source 4 is disposed on an inner surface of a side wall of the back plate 1, the LGP2 has a bottom surface and a light-emitting surface opposite to each other, a light-emitting surface is disposed on a side of the LGP2 close to the film frame 3, a reflective coating 5 is disposed on a bottom surface of the LGP2, and the reflective coating 5 is used to replace a reflective sheet in a conventional backlight frame.

A tin foil sheet 6 is disposed between the LGP2 layer and the back plate 1, and the area of the tin foil sheet 6 is greater than that of the bottom surface of the LGP 2.

A hot melt adhesive film 7 is provided between the LGP2 and the tin foil sheet 6.

The hot melt adhesive film 7 connects the LGP2 and the tin foil sheet 6 through a hot melt process.

Still include plastic part 8, backplate 1 is spacing fixed to diaphragm framework 3 through plastic part 8.

In the manufacturing process of the internal structure of the back plate 1, the hot melt adhesive film 7 is firstly hot-melted, then the LGP2 and the tin foil sheet 6 are subjected to hot press forming, and the tin foil sheet 6 plays a role in isolating the light source to prevent part of the light source from penetrating.

Principle of

By adding the reflective coating 5 on the lower surface of the LGP2, the lower surface of the LGP2 is directly coated with reflective particles, so that the LGP2 and the LGP are combined into a whole and have functions of an original LGP2 and a reflective sheet, and the two-in-one LGP2 can effectively reduce labor cost and cause poor defects such as foreign matter white spots in the operation process
