Stereoscopic grating material

Abstract

The invention discloses a stereoscopic grating material and relates to a grating material required by a stereoscopic backlight advertising. The stereoscopic grating material aims at solving two problems that firstly, the contrapuntal difficulty of stereoscopic pictures generated by the grating material and a printing manner or a digital printing manner is not reduced in a manner of low cost; and secondly, based on the limit to the precision (2400 dpi) of the existing conventional computer hardware, design software and output equipment, the higher grating precision is not realized. In order to solve the above technical problems, the stereoscopic grating material is realized by the following technical scheme: the stereoscopic grating material consists of a transparent base material 1 and a light shading layer 2 absorbed onto the base material 1; either of the light shading layer 2 and a light transmission part of the base material 1 is formed by uniformly distributing points with identical shapes and sizes according to certain requirements, and the residual part forms another part. The stereoscopic grating material is used for manufacturing stereoscopic visual effect pictures of a backlight.

Description

technical field [0001] The invention relates to a grating material required for backlight three-dimensional advertisements. Background technique [0002] Chinese Patent Publication No. CN1408567, published on April 09, 2003, the name of the invention is a light-passing panel with ordered light-shielding parts. The invention application discloses a light-transmitting plate with ordered light-shielding parts, which relates to a coated product, which is used for the outer covering layer of a three-dimensional picture. It includes a transparent sheet with a shading layer on the surface of the sheet; the shading layer is in the form of slender stripes, the stripes have a certain length, the stripes have a certain width, the width of each stripe is equal, and there is a certain distance between one stripe and another stripe. The spacing distances are equal; and the light-shielding layer is an ink with a certain light-shielding ability. [0003] Its disadvantages are: First, this...

AI Technical Summary

Problems solved by technology

[0003] Its disadvantages are: First, this kind of grating material, that is, a light-transmitting plate with ordered shading parts, its grating is composed of elongated and equidistant stripes in an orderly manner, and the three-dimensional pictures produced by printing or digital printing When aligning with it, there is an alignment between the grating lines and the lines in the three-dimensional picture. In the process, the alignment work is difficult and the scrap rate is high; second, the grating material of this kind of grating is composed of slender stripes at equal intervals in an orderly manner, based on the current conventional computer hardware, design software and output device accuracy (2400dpi ) limitation, the accuracy of the grating that can be produced is relatively low, and after aligning with the three-dimensional picture produced by printing or digital printing, the three-dimensional space of the picture is not large enough
