Abstract
The invention discloses a columnar grating material based on UV printing, which does not need to be pasted and can be used for watching a 3D effect by matching with a three-dimensional image output by printing (printing and developing); it is characterized by comprising: UV printer, UV printing varnish, varnish curing lamps, ps transparent sheet or pmma transparent sheet or ultra white glass. Through the mode, the production problem of 3D raw materials can be reduced, compared with the prior art that the raw materials can only be produced through a process of manufacturing a die, correcting the die and producing the raw materials in a mass mode, the method is easy to produce, the production efficiency is improved, and the production cost is reduced.
Description
Technical Field
The invention relates to the field of materials, in particular to a raw material of a columnar grating.
Background
The appearance of the stereoscopic display technology is another technical revolution after black and white are replaced by colors in the image field, and naked eye stereoscopic display is a development trend of the display industry. The naked eye 3D display technology is the latest and leading-edge high-tech technology in the image industry, changes the visual fatigue brought to people by the traditional plane image and is a qualitative change. The technology for realizing naked eye 3D display mainly includes two technologies, namely, light barrier type and cylindrical lens type (also called micro cylindrical lens type), and the latter does not affect the screen brightness as the former does, so the display effect of the cylindrical lens technology is better. The lenticular 3D technique positions the image plane of the liquid crystal screen at the focal plane of the lens so that the pixels of the image beneath each lenticular lens are divided into several sub-pixels, and the lens can project each sub-pixel in a different direction. The eyes then see different sub-pixels from different angles.
The naked eye 3D display device adopting the cylindrical lens 3D technology utilizes the characteristic that two eyes of a person have parallax error to obtain a display system with vivid images of space and depth. The naked eye stereoscopic image is deeply favored by consumers due to the real and vivid expressive force, the environment infectivity and the strong shocking visual impact.
However, in the naked-eye 3D display device adopting the lenticular 3D technology in the prior art, there is a strict spatial position relationship between the column pixels of the liquid crystal panel and the lenticular array film. Because the physical size of a single pixel and the cylindrical lens array is extremely small, if the installation has tiny deviation, the transmission path of emergent light can be changed, and the independent visual area is deformed to seriously influence the stereoscopic display effect. Moreover, the relative position and the sight angle of the optical device cannot be accurately adjusted by adopting naked eyes for assembly, and the mechanical precision of installation is difficult to determine; and the instruments dedicated to assembly are very expensive. In order to realize the permanent fixation of the assembly of the column pixels and the cylindrical lens array diaphragm and reduce the assembly cost, a naked eye 3D display device with high assembly efficiency and low cost and an assembly method thereof are needed.
Disclosure of Invention
The invention mainly solves the technical problem of providing a columnar grating material based on UV printing, and can solve the problem that the existing 3D material can only be produced in batches through a mould.
