Abstract
The utility model discloses a kind of backlight and liquid crystal display module.The backlight includes glue frame, the light guide plate being arranged in the glue frame, the light emitting source for being arranged on light guide plate incidence surface, the first optical film is provided with the exiting surface of the light guide plate, first optical film is sticking area close to one end of light emitting source, and black glue is pasted with the sticking area, the one end of sticking area away from the light emitting source of first optical film is provided with some horizontal otch.Some cross sections on first optical film of the backlight can pull power with what expanded by heating between completely cut off black glue and the first optical film or contraction were formed, the main part of the first optical film will not be transmitted to by making to pull power, and the first optical film would not also produce fold.
Description
Technical field
The utility model is related to field of backlights, more particularly to a kind of backlight and liquid crystal display module.
Background technology
In existing back light source structure, lighted uniformly, it is necessary in diffusion barrier close to LED/light source at LED/light source in order that obtaining
One end paste the wide black glue of a 0.6mm ~ 1mm, for absorbing at the FPC of backlight to the light spilt above screen
Line so that backlight Integral luminous is uniform.But, in temperature changing process, if the expansion rate of diffusion barrier and black glue is swollen
Swollen rate is different, may result in produce between the two it is mutual pull power, cause diffusion barrier to produce fold.
A kind of backlight is claimed in the utility model patent of a Application No. 201621323364.4, the backlight bag
Include the first optical film and the black glue being pasted onto on first optical film, the black glue and first optical film correspondence
The region of black glue is provided with some otch.The backlight corresponds to the black glue together with the first optical film in the region of black glue
By some longitudinal otch, some separate parts are divided into, by one between the black glue and the first optical film
It is individual it is big pull power, be divided into it is some it is small pull power, prevent both in temperature changing process because it is mutual pull power lead
The first optical film is caused to produce fold, still, the power of pullling between the black glue and the first optical film is simply disperseed, not
Have and prevent completely, the first optical film still can produce fold.
Utility model content
In order to solve above-mentioned the deficiencies in the prior art, the utility model provides a kind of backlight and liquid crystal display module.Should
Some cross sections on first optical film of backlight can be with expanded by heating between completely cut off black glue and the first optical film
Or shrink formed pull power, the main part of the first optical film will not be transmitted to by making to pull power, and the first optical film also would not
Produce fold.
Technical problem to be solved in the utility model is achieved by the following technical programs：
A kind of backlight, including glue frame, be arranged in the glue frame light guide plate, be arranged on the luminous of light guide plate incidence surface
The first optical film is provided with source, the exiting surface of the light guide plate, first optical film is stickup close to one end of light emitting source
Be pasted with black glue on region, and the sticking area, the sticking area of first optical film away from the light emitting source one
End is provided with some horizontal otch.
Further, the quantity of the otch is 1 ~ 10.
Further, side of the light guide plate away from exiting surface is provided with reflector plate.
Further, at least provided with the second optical film on first optical film.
Further, the light emitting source includes FPC and some LED being welded on the FPC.
Further, it is provided with anti-dazzling screen on the glue frame.
A kind of liquid crystal display module, including above-mentioned backlight.
The utility model has the advantages that：Some cross sections on first optical film of the backlight can be with complete
That blocks that expanded by heating between black glue and the first optical film or shrink formed entirely pulls power, and first will not be transmitted to by making to pull power
The main part of optical film, the first optical film would not also produce fold.
Brief description of the drawings
The schematic diagram for the backlight that Fig. 1 provides for the utility model；
Fig. 2 is the schematic diagram of the first optical film of the backlight shown in Fig. 1.
Embodiment
The utility model is described in detail with reference to the accompanying drawings and examples.
Embodiment one
As illustrated in fig. 1 and 2, a kind of backlight, including glue frame 1, be arranged in the glue frame 1 light guide plate 2, be arranged on and lead
The first optical film 4 is provided with the light emitting source 3 of the incidence surface of tabula rasa 2, the exiting surface of the light guide plate 2, first optical film 4 is leaned on
One end of nearly light emitting source 3 is to be pasted with black glue 5 on sticking area 42, and the sticking area 42, first optical film 4
The one end of sticking area 42 away from the light emitting source 3 is provided with some horizontal otch 43.
Some horizontal otch 43 on first optical film 4 of the backlight, can be by the main body of first optical film 4
Part 41 and the cut-out of sticking area 42 are separated into separate two parts, in heat shrinkable, the black light of glue 5 and first
What expanded by heating or contraction were formed between the sticking area 42 of film 4 pulls power, can be truncated, pull at horizontal otch 43
Power will not be transmitted to the main part 41 of first optical film 4, and the main part 41 of first optical film 4 would not also be produced
Raw fold, the display effect of backlight is not just influenceed yet.
