Problems solved by technology

At present, there are some technologies that can realize the suspended display in the air. For example, the scheme based on retroreflection and beam splitter can realize the suspended display of the image, but this kind of technology usually needs to use a microstructure screen with a series of very fine three-dimensional features.
For example, in the prior art, there are a series of triangular pyramid light reflective screens. Since the microstructures of these three-dimensional features are very fine, it is very difficult to arrange countless three-dimensional feature microstructures evenly and densely on a screen, and the processing accuracy is difficult to guarantee. , processing efficiency and yield are difficult to guarantee
[0004] The publication number is CN108269511A, an aerial suspension display sy

Abstract

The invention relates to the field of 3D display, and discloses a reflective geometric holographic film based on two-dimensional characteristics, and a preparation method and application thereof. Thereflective geometric holographic film comprises a series of pentagonal columnar primitive prisms with cross sections being first right-angled triangles or combinations of rectangles and second right-angled triangles, and the pentagonal columnar primitive prisms are used for retroreflecting light irradiated on the pentagonal columnar primitive prisms; a plurality of transparent layers and reflecting layers which are arranged at intervals are arranged in the columnar primitive prisms along the length direction; a layer of reflecting film is arranged on the inclined plane where the right-angle side of the cross section of each columnar primitive prism is located, and the error range of the right angles contained by the first right triangles and the pentagons and the angles formed by the reflecting layers and the length directions of the columnar primitive prisms is within +/-5 degrees. Through simple cutting and machining based on two-dimensional characteristics, the process cost is low,and large-scale production is easy to achieve; the primitive film is preferably a flexible primitive film, the product yield is high; and due to the flexible characteristic, the product can meet the requirements for folding, winding, storage and the like.

Description

technical field [0001] The invention relates to the field of 3D display, in particular to a reflective geometric holographic film based on two-dimensional features and its preparation method and application. Background technique [0002] The 3D display technology that can display a three-dimensional image in space will be the most important display technology in future life. The current mainstream 3D display is still a pseudo 3D display technology based on stereoscopic image pairs based on binocular parallax. This display method itself has many disadvantages, and it will also cause problems such as visual fatigue for users, so it is impossible to become the mainstream display technology in the future. [0003] The display method that can form a real three-dimensional picture in the air, and can display the three-dimensional picture in the most realistic way, is the trend of future display technology development. At present, there are some technologies that can realize floa...
