Abstract
The utility model relates to a structure of a light modulation element, and mainly provides a light modulation element without the formation of light band zones and dark band zones. The utility model can effectively distribute light rays of a luminaire. A back light assembly is provided with a light modulation element on the interval part of the luminaire at least. Diffused light rays on both sides of the luminaire are appropriately reflected after penetrating the light modulation element, and are uniformly emitted to a diffuser plate under the reflection function, and thus the dark band zones between luminaires are eliminated. The utility model effectively solves the topic of the existing liquid crystal mould assembly that the light band zones and the dark band zones are obviously displayed.
Description
Technical field
The utility model relates to the structure of Light modulating device, mainly provides one and is unlikely and forms Light modulating device bright, the blanking bar district, can more effectively distribute the light of light source.
Background technology
Shown in Figure 1A, be the general known back light module unit structure cut-open view of liquid crystal module, it is to be equipped with a reflection shield 10, some light sources 20, diffuser plate 30, following diffusion sheet 40, prismatic lens 50 from inside to outside in regular turn that the structure of whole module backlight is formed; Reflecting polarized wafer or last diffusion sheet 60, and liquid crystal panel 70; Wherein, each light source 20 can be the fluorescent tube of vertical bar shape or U type or other continuous bending shapes and is laid between reflection shield 10 and the diffuser plate 30 with suitable spacing, and the display effect of its liquid crystal module promptly is made of the light that each light source 20 sheds; And several blooming pieces of 70 of also common on the market this diffuser plate 30 and liquid crystal panels can by 1～3 diffusion sheet, 0～2 brightening piece, 0～1 reflecting polarized wafer etc. mutually collocation form, its effect is to make the light that passes through form diffusion, produce because of dull thread at the position at interval so as to improving, and on liquid crystal module, form phenomenon bright, the blanking bar district over against each light source 20.
Again, because the effect of diffuser plate 30 is only evenly spread at the light that order is passed through, liquid crystal module is bright for improving, the effect of blanking bar district phenomenon is limited, therefore be the gap that some module backlight painstakingly elongates light source 20 and diffuser plate 30, in the hope of enlarging the scope that each light source 20 enters diffuser plate 30, reach the purpose of dwindling dim zone; Yet so not only effect is quite limited for structural design, and the thickness of module backlight will be increased, and disagrees with the lightening design original intention of liquid crystal module.
Moreover the surface that some module backlight is selected at diffuser plate imposes the delustring processing, and it is to print at diffuser plate to contain silicon dioxide (SiO
2) or titania (TiO
2) printing ink so that the surface of diffuser plate forms delustring (astigmatism) function, so as to reaching the purpose of dwindling dim zone; Yet, so the practice not only increases the manufacturing cost of diffuser plate, and make manufacture process be tending towards loaded down with trivial details, and it is to produce photoextinction in irradiate light behind the diffuser plate surface, it obviously presents bright, comparatively passiveness, passive of blanking bar district means in order to solve known liquid crystal module, still has the space of further improvement.
Also occur the module backlight shown in Figure 1B on the market, wherein, on reflection shield 10, be formed with several Light modulating devices 12, to reflect of the light reflection of material surface, to eliminate the dim zone between each light source light source by these Light modulating device 12 height own; Yet this Light modulating device 12 is to be made into integration with reflection shield 10, only can do reflective light modulation, can't form the dimming function of refraction type or diffuse transmission type.
