Description
Technical field
The present invention relates to a kind of diaphragm fixture 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, one of the liquid crystal display television of this narrow frame or implementation of display are positioned over diaphragm on glue frame 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, 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), and LED-backlit module is by the light source that on LED lamp bar 50, light emitting diode sends, and then provides liquid crystal panel required light source.In order to realize narrower border structure design, 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, in the corresponding optical diaphragm group 20 of hanging column 10, be 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, thereby 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, the width of the glue frame plane being covered under optical diaphragm group is L, L is generally 2-5cm, if the plane of placing blooming piece enters people's sight line, 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 look side ways miter angle or when above, can see the area that optical diaphragm group edge cover lid width is L, be reflected to people's sense organ, occur that exactly bright, light and shade conversion etc. show abnormal.
Therefore the design of narrower frame and to coordinate good optics display effect be to develop at present the subject under discussion that machine is quite urgent and necessary.
Summary of the invention
The present invention relates to a kind of LED-backlit module that reaches the function of 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, on edge part, be provided with hanging column, in the corresponding optical diaphragm group of hanging column, be 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 edge part and is connected, 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 with the edge part thickness of glue frame, in support portion and edge part junction because thickness difference forms a bending part.
Wherein, from the Vertical Square glue frame that looks up, the support portion of glue frame and the junction of edge part are positioned at through hole edge or the through hole inside of optical diaphragm group.
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, thereby reaches the function of improving liquid crystal module optical effect.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the amendment of the various equivalent form of values of the present invention.
The present invention discloses a kind of fixture 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, on edge part 12, be provided with hanging column 11, in the corresponding optical diaphragm group 20 of hanging column 11, be 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, thereby optical diaphragm group 20 is fixed on glue frame 10.
Glue frame 10 be also provided with connect from edge part 12 and with edge part color different support portion 13, in the time that 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 parts of glue frame remain that white or black makes, be made up of Transparent color material support portion 13, because the effect of optical diaphragm group 20 is to allow light pass through, be arranged to Transparent color by support portion 13, can not hinder like this pass through effect of light to optical diaphragm group 20, thereby reach the function of improving optical effect.
Although support portion 12 is integrally formed with the main body of glue frame 10, but between being connected, the main body of support portion 13 and glue frame 10 there is the bending structure of a drop, also: the thickness of support portion 13 lower than with edge part 12 thickness of glue frame, form a bending part 123 in support portion 13 and edge part 12 junctions because of thickness difference, the bending part 123 of glue frame is in order to control the Swelling and contraction of optical diaphragm group.
First optical diaphragm group is passed to through hole 21 by hanging column 10, optical diaphragm group 20 is fixed on the edge part 12 of glue frame by double faced adhesive tape (not shown) again, see glue frame from vertical direction, the support portion 13 of glue frame and the junction of edge part 12 are positioned at through hole edge or the through hole inside of optical diaphragm group 20, can guarantee that like this edge part 12 there will not be below optical diaphragm group 20.
For better support of optical diaphragm group 20, the width of described support portion is 1/3 of edge part width, and what make that the width of support portion does is wider, the relatively existing width that dwindles edge part, thus can reach the object of narrow frame.
When people are near LCDs and look side ways miter angle or when above, the support portion of Transparent color is reflected to people's sense organ, there will not be show abnormal.
