Naked-eye 3D imaging grating and preparation method thereof

Abstract

The invention discloses a naked-eye 3D imaging grating and a preparation method thereof. The naked-eye 3D imaging grating comprises a lower portion base layer and an upper portion surface layer, wherein the base layer comprises successively-arranged trapezoid-like structures, each trapezoid-like structure comprises an upper bottom edge, a lower bottom edge and two symmetric side edges, and symmetric fold line steps are arranged on the two side edges of each trapezoid-like structure; each symmetric fold line step comprises an inclined edge and a vertex angle, the inclined edges of the fold line steps on the side edges at the same side are parallel to one another and are equal in length, and angles of the vertex angles are equal and further equal an included angle between the inclined edge of each bottommost fold line step and the lower bottom edge; and the surface layer is of a structure which is complementary to that of the base layer and fills up the base layer, and the base layer and the surface layer are embedded together to form an integrated upper-lower biplane structure. The naked-eye 3D imaging grating has the advantages of short development period and low manufacturing cost, solves the problem that the clarity of a planar image is affected when the existing lens imaging material is used for viewing the planar image, and is more suitable for popularization and application in mobile terminal products.

Description

technical field [0001] The invention relates to the technical field of naked-eye 3D imaging, in particular to a naked-eye 3D imaging grating and a preparation method thereof. Background technique [0002] Glasses-free 3D is to use the parallax characteristics of the two eyes to obtain realistic three-dimensional images with space and depth without any auxiliary equipment (such as 3D glasses, helmets, etc.). Glasses-free 3D technology gets rid of the shackles of auxiliary equipment and enables people to watch stereoscopic images more intuitively. At present, the technology of applying glasses-free 3D to mobile terminal products is developing faster and faster. There are generally two types of naked-eye 3D display materials applied to mobile terminals: liquid crystal imaging materials and lens imaging materials. Among these two materials, liquid crystal imaging materials have high cost and long development cycle; lens imaging materials have low cost and short development cycle...

Problems solved by technology

There are generally two types of naked-eye 3D display materials applied to mobile terminals: liquid crystal imaging materials and lens imaging materials. Among these two materials, liquid crystal imaging materials have high cost and long development cycle; lens imaging materials have low cost and short development cycle. But there will be some impact when viewing flat images, which will reduce the clarity of flat images
