Description

A kind of grating and preparation method thereof
Technical field
The invention belongs to display technique field, relate to bore hole 3D display technique, be specially a kind of without prismatic lens grating and preparation method thereof.
Background technology
Along with the popularization and application of 3D display technique, the research of the bore hole 3D display technique of more convenient propagation is also more and more deep compared with spectacle 3D technology.In bore hole 3D display technique, post lens type bore hole 3D display technique is an important research direction of bore hole 3D display technique, Lenticular screen is to be arranged in parallel and to be formed microtrabeculae lens arra by numerous identical microtrabeculae lens, its principle is that 2D display location is on the focal plane of Lenticular screen, in the orientation of post lens unit, different directions is arrived in each width anaglyph anaclasis of diverse location on its focal plane by each post lens unit, make the beholder's right and left eyes that is positioned at suitable viewing location see different images, produce parallax, thereby make beholder produce stereo-picture at brain.This class bore hole 3D display technique stereoeffect is good, and brightness is not affected, and is widely used.As the critical component of this class bore hole 3D display technique, Lenticular screen has directly determined the success or failure of post lens type bore hole 3D display technique.In the structure of bore hole 3D display device, Lenticular screen is installed in whole equipment foremost, and microlens array outwardly, microtrabeculae lens arra is easily damaged and scratches like this, if add cover glass, just there will be two problems, first has reduced the brightness of bore hole 3D display device, affects 3D display effect; Second increases the weight of whole display device.In post mirror bore hole 3D display technique, the aligning accuracy of Lenticular screen and liquid crystal display requires high, because there is rib on traditional Lenticular screen surface, be difficult at present use sucked type automation equipment to carry out grating contraposition, current alignment method still manually carries out, and aligning accuracy is limited and efficiency is very low.
Summary of the invention
The object of the present invention is to provide a kind of without prism grating and preparation method thereof.
For achieving the above object, the technical scheme that the present invention proposes is:
A kind of grating, comprises substrate and is distributed in the microtrabeculae lenticulation array on substrate, in the present invention, also comprises the packed layer covering on microtrabeculae lenticulation array, and the inner face of described packed layer is filled and led up the male and female face of microtrabeculae lenticulation array, and it is smooth that outside surface keeps.Described substrate is consistent with the index of refraction of microtrabeculae lenticulation array, and the index of refraction of packed layer is less than above-mentioned two-layer.
Further, described microtrabeculae lenticulation array and packed layer are two kinds of different ultraviolet curing liquid glues.
Based on above-mentioned grating, its preparation method is:
(1) adopt nanometer embossing on substrate, to suppress layer of transparent film, be then etched to microtrabeculae lenticulation array, and solidify processing;
(2) adopt nanometer embossing to suppress layer of transparent film on above-mentioned microtrabeculae lenticulation array, make its space of filling and leading up the male and female face that microtrabeculae lenticulation array stays, and keep the smooth of outside surface, after compressing, solidify and process, form packed layer, obtain grating.
In above-mentioned steps, curing being treated to adopts cold ultraviolet light equipment to carry out treatment with irradiation, for improving the precision of grating.
In the present invention, the index of refraction of described microtrabeculae lenticulation array is greater than the index of refraction of packed layer, has formed microtrabeculae lens arra optical grating construction; The outermost layer of grating is the packed layer of transparent membrane, can protect the transparent array structure of microtrabeculae not damaged; The robotization that preparation technology can impel bore hole 3D display device to produce grating is simultaneously carried out, and effectively improves aligning accuracy and production efficiency; The present invention has adopted nanometer embossing, effectively raises the precision without prismatic lens grating.Compared with prior art, explained hereafter efficiency of the present invention is high, and for preparing is high without prism grating precision, long service life.
Brief description of the drawings
Fig. 1 is the structural representation of grating of the present invention.
Fig. 2 is the preparation flow schematic diagram of grating of the present invention.
In figure: substrate 1, microtrabeculae lenticulation array 2, packed layer 3.
Embodiment
Below in conjunction with Figure of description, the invention will be further described with concrete preferred embodiment, but protection domain not thereby limiting the invention.
A kind of grating shown in Figure 1, comprise substrate 1, microtrabeculae lenticulation array 2 and packed layer 3 three-deckers, wherein microtrabeculae lenticulation array 2 covers above substrate 1, for concavo-convex microtrabeculae lenticulation array transparent membrane, packed layer 3 covers above microtrabeculae lenticulation array 2, fill and lead up the space of microtrabeculae lenticulation array 2 male and female faces, it is smooth that outside keeps.
Preparation method shown in Figure 2, its idiographic flow is:
(1) on substrate, apply the ultraviolet curing glue of layer of transparent, use mould to adopt nanometer embossing compacting to be etched to the structure of microtrabeculae lenticulation array, and be cured processing, slough mould, above substrate, forming one deck microtrabeculae lenticulation array transparent membrane, is microtrabeculae lenticulation array.
In this step, this mould is high-precision microtrabeculae lenticulation array mold, and the index of refraction after ultraviolet curing adhesive curing and the index of refraction of baseplate material are basically identical.
(2) on microtrabeculae lenticulation array, apply the another kind of transparent ultraviolet curing glue of one deck, use smooth flat board to adopt nanometer embossing that ultraviolet curing glue is filled to the gap between dull and stereotyped and microtrabeculae lenticulation array completely, and be cured processing, slough after flat board, forming layer of transparent film in microtrabeculae lenticulation array surface, is packed layer.Packed layer has been filled and led up the microtrabeculae lens arra of microtrabeculae lenticulation array completely, and has completed the preparation without prism grating.
Index of refraction after the ultraviolet curing adhesive curing adopting in this step is less than the index of refraction of substrate and microtrabeculae lenticulation array, ensures the effect of grating; The dull and stereotyped smooth surface adopting, it is smooth without prism grating outside surface that guarantee makes.
