Description

A kind of backlight module
Technical field
The present invention relates to a kind of diaphragm stationary installation of LED-backlit module.
Background technology
Along with people progressively promote the requirement of liquid crystal display television or display appearance design attractive in appearance, have the life that the liquid crystal display television of narrow frame design theory or display enter people, diaphragm is positioned on glue frame by one of this liquid crystal display television of narrow frame or the implementation of display exactly.Figure 1 shows that the STRUCTURE DECOMPOSITION schematic diagram of existing LED-backlit module, existing LED-backlit module comprises: glue frame 10, optical diaphragm group 20, diffuser plate 30, reflector plate 40, LED lamp bar 50 and backboard 60, and optical diaphragm group 20 comprises 2 or multiple prismatic lens.Wherein LED lamp bar 50 is made up of light emitting diode (LED) and printed circuit board (PCB) (PCB/PWB), the light source that LED-backlit module sends by light emitting diode in LED lamp bar 50, and then provides the light source needed for liquid crystal panel.In order to realize the design of narrower border structure, generally that optical diaphragm group 20 is positioned on glue frame 10, its optical diaphragm group 20 is fixed on structure on glue frame 10 as shown in Figure 2: the edge of glue frame 10 is provided with hanging column 11, the optical diaphragm group 20 that hanging column 10 is corresponding is provided with through hole 21, the through hole 21 of optical diaphragm group 20 is sticked on the hanging column 11 of glue frame 10, thus optical diaphragm group 20 is fixed on glue frame 10.
Although the mode of existing fixed optics diaphragm group 20 is simple, glue frame 10 needs enough wide plane to place optical diaphragm group, as shown in Figure 2, be L by the width of the glue frame plane covered under optical diaphragm group, L is generally 2-5cm, if the plane of placing blooming piece enters the sight line of people, will give people's difference uncomfortable display effect sense.So, narrow frame liquid crystal display television in the past or the diaphragm lay down location of display, as shown in Figure 3, people near display screen and when looking side ways miter angle or more, can see that optical diaphragm group edge cover lid width is the area of L, be reflected to the sense organ of people, occur bright piece exactly, the display such as light and shade conversion is abnormal.
Therefore narrower frame design and coordinate good optics display effect to be develop the quite urgent and subject under discussion of necessity of machine at present.
Summary of the invention
The present invention relates to a kind of LED-backlit module reaching the function improving liquid crystal module optical effect.
The invention provides a kind of LED-backlit module, comprise: glue frame, optical diaphragm group, LED lamp bar, and backboard, described optical diaphragm group, LED lamp bar, and backboard is all fixed in glue frame, glue frame is provided with the edge part of fixed optics diaphragm group, edge part is provided with hanging column, the optical diaphragm group that hanging column is corresponding is provided with through hole, the through hole of optical diaphragm group is sticked in the hanging column of glue frame, glue frame is also provided with and is connected with edge part, and the support portion of support of optical diaphragm group, the color of this support portion is different from the color of edge part, described support portion is that transparent color material is made.
Wherein, the edge part of described support portion and glue frame adopts the technique of double-material injection-molding to be integrally formed.
Wherein, edge part is made up of white or black.
Wherein, the thickness of support portion, lower than the edge part thickness with glue frame, forms a bending part in support portion and edge part junction because of thickness difference.
Wherein, to look up glue frame from Vertical Square, the support portion of glue frame and the junction of edge part be positioned at the through hole edge of optical diaphragm group or through hole inner.
Wherein, the width of described support portion is 1/3 of edge part width.
Glue frame of the present invention adopts the technique of double-material injection-molding, and main part is still white or black, and the support portion of placing diaphragm adopts Transparent color material to make, thus reaches the function improving liquid crystal module optical effect.

Embodiment
Below in conjunction with the drawings and specific embodiments, illustrate the present invention further, these embodiments should be understood only be not used in for illustration of the present invention and limit the scope of the invention, after having read the present invention, the amendment of those skilled in the art to the various equivalent form of value of the present invention has all fallen within the application's claims limited range.
The present invention discloses a kind of stationary installation of diaphragm of LED-backlit module, be illustrated in figure 1 the structural representation of general LED-backlit module, LED-backlit module comprises: glue frame 10, optical diaphragm group 20, diffuser plate 30, reflector plate 40, LED lamp bar 50 and backboard 60, in the present embodiment, optical diaphragm group 20 comprises 3 prismatic lenses, what Fig. 1 illustrated is direct-light type LED backlight module, and the present invention is also used in the LED-backlit module of other types.
Same as the prior art, glue frame 10 is provided with the edge part 12 of fixed optics diaphragm group 20, edge part 12 is provided with hanging column 11, the optical diaphragm group 20 that hanging column 11 is corresponding is provided with through hole 21, the through hole 21 of optical diaphragm group 20 is sticked on the hanging column 11 of glue frame 10, thus optical diaphragm group 20 is fixed on glue frame 10.
Also be provided with at glue frame 10 and connect and the support portion 13 different with edge part color from edge part 12, when optical diaphragm group 20 is fixed on glue frame 10, this support portion 13 is covered by optical diaphragm group 20.
Described support portion 13 adopts the technique of double-material injection-molding to be integrally formed with the edge part 12 of glue frame 10, edge part 12 part of glue frame remains that white or black makes, support portion 13 is made up of Transparent color material, effect due to optical diaphragm group 20 allows light pass through, Transparent color is arranged to by support portion 13, can not hinder like this light to optical diaphragm group 20 by effect, thus reach the function improving optical effect.
Although support portion 12 is integrally formed with the main body of glue frame 10, but support portion 13 has the bending structure of a drop between being connected with the main body of glue frame 10, also namely: the thickness of support portion 13 is lower than edge part 12 thickness with glue frame, in support portion 13 with edge part 12 junction because thickness difference forms a bending part 123, the bending part 123 of glue frame is in order to the Swelling and contraction of control both optical diaphragm group.
First optical diaphragm group is passed through hole 21 by hanging column 10, by double faced adhesive tape (not shown), optical diaphragm group 20 is fixed on the edge part 12 of glue frame again, glue frame viewed from vertical direction, support portion 13 and the junction of edge part 12 of glue frame are positioned at through hole edge or the through hole inside of optical diaphragm group 20, can guarantee that edge part 12 there will not be below optical diaphragm group 20 like this.
In order to better support of optical diaphragm group 20, the width of described support portion is 1/3 of edge part width, and what the width of support portion was done is wider, the relatively existing width reducing edge part, thus can reach the object of narrow frame.
When people are near LCDs and when looking side ways miter angle or more, the support portion of Transparent color is reflected to the sense organ of people, there will not be display abnormal.
