The area source that LCD TV needs module backlight to provide could normally show image, and module backlight is divided into side entering type and down straight aphototropism mode set according to the light inlet mode difference of light source.As shown in Figure 1 be the assembling schematic diagram of present each discrete optical element of down straight aphototropism mode set, wherein, main optical element comprises light source 120, reflector plate 110, diffuser plate 130, diffusion sheet 140, blast sheet 150, composite membrane 160 etc.During assembling, the matched combined that stacks gradually by above-mentioned each optical element reaches good brightness uniformity, satisfies LCD TV the best and looks the effect requirement.
At present, the composite membrane of blooming piece has diffusion and the effect of blast concurrently in the optical element; Diffuser plate has also been done micro-structural to have the function of diffusion and blast concurrently in some novel products.Optical element such as composite membrane and novel diffuser plate all has to a certain degree integrated, also can satisfy design and the production requirement of down straight aphototropism mode set in actual applications.But in down straight aphototropism mode set was produced, optical element was still more, and each optical element still needs discrete assembling, is unfavorable for the production efficiency of module backlight, and rigging error influences whole optical effect backlight easily.
Therefore, prior art has yet to be improved and developed.
The utility model content
In view of above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide a kind of down straight aphototropism mode set, and it is numerous to be intended to solve present down straight aphototropism mode set optical element, the problem that the discrete assembling procedure of optical element is loaded down with trivial details.
The technical solution of the utility model is as follows:
A kind of down straight aphototropism mode set, comprise backboard and place reflector plate, light source, optical element and liquid crystal panel on the described backboard successively, described optical element comprises diffuser plate, diffusion sheet, blast sheet, composite membrane, wherein, described optical element is described diffuser plate, diffusion sheet, blast sheet, the stacked integrated optical element that is bonded together of composite membrane.
Described down straight aphototropism mode set, wherein, described diffuser plate, diffusion sheet, blast sheet, composite membrane stacks gradually and be incorporated into together by optical grade glue.
Described down straight aphototropism mode set, wherein, described optical grade glue is liquid optical cement.
Beneficial effect: the utility model provides a kind of down straight aphototropism mode set, and it is integrated diffuser plate, diffusion sheet, increment sheet, composite membrane etc. and becomes one by the optical grade glue of high permeability, make it to satisfy the optics requirement of down straight aphototropism mode set.In performance performance, this integrated optical element has better stability, can the dirt of more effective solution module stolen goods backlight, and the phenomenon of diaphragm fold, and can play the effect of strengthening diffuser plate to a certain extent; On manufacturing, this integrated optical element can assemble in module backlight is made fast, replaces traditional loaded down with trivial details discrete optical element linkage editor one by one, enhances productivity greatly.

The specific embodiment
The utility model provides a kind of down straight aphototropism mode set, and is clearer, clear and definite for making the purpose of this utility model, technical scheme and effect, below the utility model further described.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
A kind of down straight aphototropism mode set as shown in Figures 2 and 3, comprise backboard (not marking among the figure) and place reflector plate 210, light source 220, optical element 230 and liquid crystal panel (figure does not mark) on the described backboard successively, described optical element 230 comprises diffuser plate 231, diffusion sheet 232, blast sheet 233, composite membrane 234, and described optical element 230 is incorporated into integrated optical element together for diffuser plate 231, diffusion sheet 232, blast sheet 233, composite membrane 234.
Described diffuser plate 231, diffusion sheet 232, blast sheet 233, composite membrane 234 stack gradually and the optical grade glue 240 by high permeability is bonded together and forms becoming one of an integral body optical element.Guaranteeing under optical brightness and the inhomogeneity situation that the diffusion sheet 232 that stacks successively above the described diffuser plate 231, blast sheet 233, composite membrane 234 orders can change, kind also can increase and decrease.Described optical grade glue 240 can use the liquid optical cement (LOCA) that is applied in touch-screen at present, and this glue has the light transmission rate more than 90%, can satisfy the processing request of down straight aphototropism mode set of the present utility model.Optical grade glue 240 is evenly coated on the binding face of diffuser plate 231, diffusion sheet 232, blast sheet 233, composite membrane 234, made each becoming one of optical element optical element by pressing, solid glue.Glue layer between each blooming piece should keep consistency of thickness.
The utility model provides the technological process of being made into one optical element as described in Figure 4, because the surface area of each discrete optical element is bigger, evenly coating optical grade glue is difficult, in the process of integrated optical element processing, earlier optical grade glue 240 is coated on roller 1 to roller 4, rotation roller is uniformly coated on the roller by optical grade glue in advance, above roller, constantly replenish optical grade glue 240, each discrete optical element diffuser plate 231 simultaneously in right amount, diffusion sheet 232, blast sheet 233, composite membrane 234 is fitted in roller 4-1 respectively upward and evenly is coated with optical grade glue by conveyer belt surface when process scribbles the roller of optical grade glue.Each optical element is through the some glue stage, evenly behind the coating optical grade glue, before roller 5, stacking according to order up and down under the drive of conveyer belt, suitable power through roller 5 is together extrusion bonded, through the solid glue of UV baking, the size of the concrete type of basis cuts and just can obtain the integrated optical element of direct-type backlight then after coming out.
Because the area of optical element is bigger, is easy to generate bubble in optical grade glue adhesion process, and then influences the optical effect of integrated optical element.Can before adding glue, carry out heated baking to each optical element, prevent the generation of bubble to guarantee dry tack free.
The utility model provides a kind of down straight aphototropism mode set, and it is integrated diffuser plate, diffusion sheet, increment sheet, composite membrane etc. and becomes one by the optical grade glue of high permeability, make it to satisfy the optics requirement of down straight aphototropism mode set.In performance performance, this integrated optical element has better stability, can the dirt of more effective solution module stolen goods backlight, and the phenomenon of diaphragm fold, and can play the effect of strengthening diffuser plate to a certain extent.Traditional each discrete optical element all needs to add diaphragm; the processing that in producing and assembling, all needs to spend cost and manually carry out diaphragm; and integrated optical element of the present utility model integrates several optical elements, can reduce the use of diaphragm, saves time and cost.On manufacturing, this integrated optical element can assemble in module backlight is made fast, replaces traditional loaded down with trivial details discrete optical element linkage editor one by one, enhances productivity greatly.
Should be understood that; application of the present utility model is not limited to above-mentioned giving an example; for those of ordinary skills, can be improved according to the above description or conversion, all these improvement and conversion all should belong to the protection domain of the utility model claims.
