Background technology
Backlight module is one of the key part and component of panel of LCD.Function is well-off brightness and distribution
Uniform light source can normally show image.Liquid crystal display is passive light-emitting component, and display screen itself does not shine, but
It is illuminated by back light system below.Backlight and liquid crystal display, which are combined, constitutes LCD MODULE.
Existing cell phone back light source causes display screen to account for smaller, influences user's since backlight module lightproof area is larger
Mobile phone usage experience.
Utility model content
Purpose of the utility model is to solve disadvantages existing in the prior art, and a kind of ultra-narrow frame proposed
Backlight module.
To achieve the goals above, the utility model uses following technical solution：A kind of backlight module of ultra-narrow frame,
Including LED luminescence components and iron frame, the inside of the iron frame is fixed with transmitting film, and the transmitting film top is provided with light guide plate,
The side end set of the light guide plate has LED luminescence components, the top of the light guide plate to be pasted with diffusion successively from bottom to top
The upper surface of film, lower bright enhancement film and upper bright enhancement film, the upper bright enhancement film and iron frame is pasted with black and white shading glue.
As further describing for above-mentioned technical proposal：
Four sides of the iron frame are provided with rib, and the internal height of rib and light guide plate, diffusion barrier, upper bright enhancement film and under
The sum of thickness of bright enhancement film is identical.
As further describing for above-mentioned technical proposal：
The side end set of the LED luminescence components of light guide plate connection has a broached-tooth design, and light guide plate with transmitting
The end face of film connection is provided with equally distributed site.
As further describing for above-mentioned technical proposal：
The upper bright enhancement film, lower bright enhancement film, diffusion barrier and the profile width of transmitting film and the inner width of iron frame are identical.
In the utility model, module fixed frame that traditional plastic cement glue frame and iron frame are formed directly by concave iron frame into
Row replaces, and the surrounding of concave iron frame is both provided with rib, height and light guide plate, transmitting film, diffusion barrier and the increasing up and down of rib
The sum of light film thickness is identical, and the surface of iron frame and upper bright enhancement film is pasted with black and white shading glue, can be substantially reduced the back of the body in this way
It ensure that the overall structure stability of backlight module while optical mode group frame, increase product competitiveness, simple in structure, producer
Just, there is certain market popularization value.

Four sides of iron frame 8 are provided with rib, and the internal height of rib and light guide plate 6, diffusion barrier 5, upper bright enhancement film 3 and under
The sum of the thickness of bright enhancement film 4 is identical, and the side end set for the LED luminescence components 1 that light guide plate 6 connects has broached-tooth design, and leads
The end face of tabula rasa 6 being connect with transmitting film 7 is provided with equally distributed site, upper bright enhancement film 3, lower bright enhancement film 4,5 and of diffusion barrier
The profile width of transmitting film 7 is identical as the inner width of iron frame 8.
Black and white shading glue 2 is the indication range for blocking backlight module, while iron frame 8 and upper bright enhancement film 3 being glued
It is attached.
Operation principle：In production process, iron frame 8 is fixed in special frock clamp, is then attached to transmitting film 7
In iron frame 8, then the end face with site of light guide plate 6 is attached with transmitting film 7 again, later by light guide plate 6 with saw
LED luminescence components 1 are placed in the end of tooth, then attached successively on the upper surface of light guide plate 6 diffusion barrier 5, lower bright enhancement film 4 and on
Bright enhancement film 3 is finally attached upper bright enhancement film 3 and iron frame 8 by black and white shading glue 2 according to the region of visual windows, to
Complete the installation of backlight module.
