Naked eye three-dimensional presenting device, and naked eye three-dimensional presenting device manufacturing system and method

Abstract

The invention provides a naked eye three-dimensional presenting device including a two-dimensional negative film and a spatial light modulator; the two-dimensional negative film has a textured pattern; the spatial light modulator is located on the two-dimensional negative film and is composed of a transparent substrate and an optical refraction unit located on the transparent substrate; through special design based on a three-dimensional holographic technology, the textured pattern can enable a user to observe a three-dimensional image above the naked eye three-dimensional presenting device. The naked eye three-dimensional presenting device can present a three-dimensional object with a certain depth through a two-dimensional plane, and has the advantages of simple structure, low cost, small size, light weight, strong three-dimensional sense of display effect, easy stacking and storage and the like. The invention also provides a manufacturing system and a manufacturing method of the naked eye three-dimensional presenting device, wherein the manufacturing system and the manufacturing method allow 2D printing to be combined with 3D printing, and can efficiently large-scale manufacture the naked eye three-dimensional presenting device.

Description

technical field [0001] The invention belongs to the technical field of three-dimensional modeling, and in particular relates to a naked-eye three-dimensional rendering device, a manufacturing system and a manufacturing method of the naked-eye three-dimensional rendering device. Background technique [0002] At present, many physical objects are displayed, and the common processing method is machining or the three-dimensional printing method that has been popular in recent years to make objects. The biggest disadvantage of the real object is that it has a certain volume and weight, especially for large or complex objects, the cost of materials and processing is very expensive. Different from physical display, holographic projection technology has gradually been applied in product display in recent years, but the production of holographic images is relatively complicated and its display device also takes up a lot of space.

The biggest disadvantage of the real object is that it has a certain volume and weight, especially for large or complex objects, the cost of materials and processing is very expensive

Different from physical display, holographic projection technology has gradually been applied in product display in recent years, but the production of holographic images is more complicated and its display device also takes up a lot of space

[0003] Printers on the existing market include two-dimensional printers (such as inkjet printers, laser printers) and three-dimensional printers. The functions of the two printers are independent, and any printer cannot simultaneously realize the functions of two-dimensional and three-dimensional printing.
