Abstract
The utility model discloses a kind of backlight and liquid crystal display module.The light emitting source that the backlight includes glue frame, the light guide plate being arranged in the glue frame, is arranged on light guide plate incidence surface, the first optical film, first optical film are provided with the exiting surface of the light guide plate and are pasted with black glue near one end of light emitting source, the region that the black glue and first optical film correspond to black glue is provided with some otch.The backlight can prevent black glue and the first optical film in the temperature changing process because it is mutual pull power cause the first optical film to 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, in order that obtaining lighted at LED light source uniform, it is necessary in diffusion barrier near LED light source
One end paste a 0.6mm ~ 1mm black glue wide, for absorbing the light spilt to screen top from the FPC of backlight
Line so that backlight Integral luminous are uniform.But, in temperature changing process, if the expansion rate of diffusion barrier is swollen with black glue
Swollen rate is different, may result in produce between the two it is mutual pull power, cause diffusion barrier to 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
Backlight can prevent black glue and the first optical film in the temperature changing process because it is mutual pull power cause the first optics
Film produces 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
Source, is provided with the first optical film, first optical film and is pasted near one end of light emitting source on the exiting surface of the light guide plate
The region of black glue, the black glue and the black glue of first optical film correspondence is provided with some otch.
Further, the quantity of the otch is 3 ~ 5.
Further, the light guide plate is provided with reflector plate away from the side of exiting surface.
Further, at least provided with the second optical film on first optical film.
Further, the light emitting source includes the 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：The backlight is black in black glue and first optical film correspondence
The region of glue is provided with some otch, and black glue and first optical film are corresponded to the otch region segmentation of black glue
It is some separate parts, it is unaffected each other, can so reduce the drawing between black glue and the first optical film
Pull power, prevent both in the temperature changing process because it is mutual pull power cause the first optical film to produce fold.
Brief description of the drawings
The schematic diagram of the backlight that Fig. 1 is provided for the utility model；
The black glue of the backlight that Fig. 2 is provided for the utility model and the schematic diagram of the first optical film.
Specific 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, the light guide plate 2 being arranged in the glue frame 1, it is arranged on and leads
The light emitting source 3 of the incidence surface of tabula rasa 2, is provided with the first optical film 4, first optical film 4 and leans on the exiting surface of the light guide plate 2
One end of nearly light emitting source 3 is pasted with the region of black glue 5, the black glue 5 and the black glue 5 of first optical film 4 correspondence
It is provided with some otch 51.
The backlight is provided with some otch in the region of black glue 5 and the black glue 5 of first optical film 4 correspondence
51, the region segmentation of black glue 5 and the black glue 5 of first optical film 4 correspondence is some separate by the otch 51
Part, unaffected each other, can so reduce pull power between the optical film 4 of black glue 5 and first, prevent both
In the temperature changing process because it is mutual pull power cause the first optical film 4 to produce fold.
First optical film 4 is preferably but not limited to diffusion barrier.
Preferably, the quantity of the otch 51 is 3 ~ 5.
The light guide plate 2 is provided with reflector plate 6 away from the side of exiting surface, and the reflector plate 6 pastes the glue frame 1
On bottom surface；At least provided with the second optical film on first optical film 4, in the present embodiment, on first optical film 4 successively
Be provided with lower bright enhancement film 8 and upper bright enhancement film 9, but optical film type should according to the actual requirements depending on, should not be with the present embodiment
Limit；The light emitting source 3 includes the FPC 32 and some LED 31 being welded on the FPC 32, and the one end of the FPC 32 pastes
On the front of the light guide plate 2, the other end is pasted on the front of the glue frame 1；Anti-dazzling screen 7, institute are provided with the glue frame 1
State anti-dazzling screen 7 preferably two-sided with viscosity, dorsad the side of the light emitting source 3 is black flour, and the side towards the light emitting source 3 can
Being the face of black flour, or other colors.
Embodiment two
A kind of liquid crystal display module, including the backlight described in embodiment one.
Embodiment described above only expresses implementation method of the present utility model, and its description is more specific and detailed, but simultaneously
Therefore the limitation to the utility model the scope of the claims can not be interpreted as, as long as the institute in the form of equivalent or equivalent transformation
The technical scheme of acquisition, all should fall within protection domain of the present utility model.
