Abstract
The utility model relates to a novel backlight module device, in particular to a grating backlight module device for a naked-eye type 3D (three dimention) liquid crystal display. The grating backlight module device comprises a backlight box, wherein a backlight assembly is installed in the backlight box; and the grating backlight module device is characterized in that a slit grating is embedded in the backlight box, and the slit grating is installed at the front end of the backlight assembly. The grating backlight module device only needs to be directly matched with the liquid crystal display when in use, the slit grating 3D liquid crystal display can be rapidly assembled, thus the production efficiency and the finished product ratio are improved greatly, and the producton cost is reduced.
Description
Technical field
The utility model relates to a kind of novel module device backlight, particularly a kind of grating module device backlight that is used to realize bore hole formula 3D LCD.
Background technology
At present, the research and development impetus of the bore hole formula 3D LCD that need not to use glasses can watch stereopsis is just prosperous.Because right eye and left eye are at a distance of about 65mm, the scene that causes right eye and left eye to be seen thus has some differences, thereby the real world scene that human eye is seen is the 3D solid.So identical basic ideas are adopted in existing design mostly: by on the demonstration liquid crystal display, post mirror (Lenticular Lens being set, lens pillar) or slit grating (barrier, liquid crystal grating or grid) wait separate picture, make image on the liquid crystal display, corresponding right and left eyes has had directive property.When the right eye correspondence image occurred, the directive property of the effect of the blocking control light by post mirror refraction or slit grating was seen the right eye that it can only viewed person.On the contrary, when the left eye correspondence image occurred, by the effect of blocking of refraction of post mirror or slit grating, the directive property of control light can only be seen it by left eye.When treated right and left eyes composograph occurs, can see different correspondence image respectively for two of the people, this two image then can be realized 3D stereoscopic vision through remarkable brain synthesis.
In the prior art, be earlier to stick slit grating at the back side of LCDs according to being strict with (error is in 0.1mm), again itself and the module device backlight (backlight) that designs matched and finish the assembling of whole bore hole formula 3D LCD by the assembler.Adopt this mode to waste time and energy, and very big, have deviation just need paste again slightly with assembler's technical ability relevance, packaging efficiency, low yield rate is low, production cost is higher.
Summary of the invention
At above-mentioned the deficiencies in the prior art, the utility model provides a kind of novel grating module device backlight that is used for bore hole formula 3D LCD, be equipped with slit grating on it, only need directly and LCDs matches, can finish the assembling of slit grating stereo-liquid crystal display device fast, improve production efficiency and yield rate greatly, reduced production cost.
For realizing above-mentioned technical purpose, the utility model adopts following technical scheme:
A kind of grating module device backlight that is used for bore hole formula 3D LCD, include backlight box, be installed on backlight assembly in the backlight box, its difference is, also be embedded with slit grating in backlight box, described slit grating is installed in the front end of described backlight assembly.
For further realizing above-mentioned technical purpose, described backlight assembly includes reflectance coating, LGP, bright enhancement film and diffusion barrier successively, and described slit grating is installed in the front end of described diffusion barrier.
Because the utility model is to be embedded a special-purpose slit grating module device backlight that the slit grating sheet forms in the backlight box that conventional 3D LCD is used.In use, only need and easily to assemble by module device backlight, just can finish the preparation that bore hole formula 3 is tieed up liquid crystal display assemblies with liquid crystal display.During concrete the application, slit grating must calculate through strict thickness and gradient, in the hope of being complementary with liquid crystal display.
Description of drawings
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of a preferred embodiment of the utility model.
Fig. 2 is preferred embodiment side sectional view of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of a preferred embodiment of a kind of grating module device backlight that is used for bore hole formula 3D LCD of the utility model, and Fig. 2 is the preferred embodiment side sectional view.As shown in Figure 1 and Figure 2, in the present embodiment, the bottom and the colloid frame-type backlight box 10 of sealing all around are installed on reflectance coating 21, LGP 22, bright enhancement film 23 and diffusion barrier 24 successively in it, are slit gratings 30 at the front end of diffusion barrier 24.13 li of on the outer rim 31,32 of two protrusions of slit grating 30 top edges, the right hand edge one grooves that protrudes groove 11,12 that outer rim 33 is embedded in colloid backlight box 10 upperside frames respectively, right side frame.The specific design of groove can be decided as required.Two groups of sockets 14,15 on the framework of backlight box 10 left and right sides can insert inserted sheet with fixedly liquid crystal display or other assemblies.The specific design of socket also can be decided as required, and form should not limited to yet.
The utility model is to be embedded the slit grating sheet and a special-purpose slit grating module device backlight formed in the frame-type backlight box that conventional 3D LCD is used.In use, only need should module device backlight easily and liquid crystal display assemble, just finished the assembling of bore hole formula 3D LCD.During concrete the application, slit grating must calculate through strict thickness and gradient, in the hope of being complementary with liquid crystal display.
Below only be preferred forms of the present utility model, not in order to restriction the utility model.All according to the disclosed content of the utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently all should fall into protection domain of the present utility model.
Claims (4)
1. a grating module device backlight that is used for bore hole formula 3D LCD includes backlight box, is installed on backlight assembly in the backlight box, it is characterized in that also be embedded with slit grating in backlight box, described slit grating is installed in the front end of described backlight assembly.
2. grating according to claim 1 module device backlight is characterized in that described backlight assembly includes reflectance coating, LGP, bright enhancement film and diffusion barrier successively, and described slit grating is installed in the front end of described diffusion barrier.
