The camber of upper convex arc.
The preparation method of described pair of arc bore hole 3D Imaging grating comprises the following steps：
（1）According to the structure fabrication engraving cutter head and grating mold base roller of described pair of arc bore hole 3D Imaging grating, then in light
Grid mould base roller surface engraving cutter head engraving grating pattern；
（2）The grating is made using normal temperature cold pressing formula method：Require that cleanliness factor is less than or equal under conditions of 100 grades in darkroom,
PET film is first by glue spreader, and coating makes the UV photoresists used by the grating, then by grating mold roller and hold-down roller it
Between be compacted, while by solidifying lamp box apparatus, making the UV photoresists of the grating by instantaneous solidification, passing through delivery roll after solidification
Rewinding is carried out on finished product material receiving roller, described pair of arc bore hole 3D Imaging grating is to complete.
The beneficial effects of the present invention are：
1. double arc bore hole 3D Imaging gratings of the invention are using the double arcuate structures for continuously repeating arrangement, two adjacent upper convex arcs
Between seamlessly transitted by the lower concave arc of setting to realize so that the intersection of adjacent upper convex arc would not form obvious line
Strip, is attached on liquid crystal display such bore hole 3D image forming materials later just close to the one layer plane film in liquid crystal display overlying,
It using such optical grating construction, can effectively weaken the crosstalk between liquid crystal display pixel lines, improve when watching plane
The light wave phenomenon of appearance.
2. the imaging effect of double arc bore hole 3D Imaging gratings of the invention is more preferable, it is possible to achieve good bore hole 3D imaging effects
Really, perception is more comfortable；The viewing of plane picture is not interfered with again simultaneously, the double arc bore hole 3D Imaging gratings of the present invention make
Low cost, construction cycle are short, are a kind of display materials for the mobile terminal that is particularly suitable for use in.
