Suspension imaging optical film

Abstract

The invention discloses a suspended imaging optical film, comprising a first polymer with a first surface and a second polymer with a second surface, the first surface and the second surface are opposite; the first surface is formed with a microlens structure , the microlens structure includes a number of microfocusing units; the second surface is formed with an accommodation structure, and the accommodation structure accommodates a number of graphic structures imaged by the microlens structure; the adjacent part between the first polymer and the second polymer is formed with Fusion part, so that the microlens structure and the containing structure are integrated; the micro-focusing unit is adapted to the graphic structure, so that the suspended imaging optical film can be viewed from the graphic structure side or from the micro-focusing unit side A suspended image suspended in the suspended imaging optical film is formed, and the suspended image formed by the suspended imaging optical film is a single-channel pattern or a multi-channel pattern. The purpose of the suspension imaging optical film is to reduce the thickness of the suspension imaging optical film.

Description

Technical field [0001] The present invention relates to the field of suspension imaging optical film, and more particularly to a suspended imaging optical film. Background technique [0002] Various three-dimensional imaging technology has received more and more attention in information, showing, medical, military and other fields. Three-dimensional imaging is achieved by microlens technology, with very potential and prospects. It comes from G.LIPPMAN's development of integrated photography proposed in 1908. A set of two-dimensional unit images with different perspective relationships of three-dimensional scenes are collected by a lens array and an image, and a three-dimensional image of the original scene can be directly observed in front of the display microlens array without special observation glasses and illumination. With the development of microlens array manufacturing process, integrated imaging technology attracts more and more attention, integrated imaging and display t...

Problems solved by technology

The structure mentioned in the patent has three defects: 1. Since the transmission microlens array is used, the total thickness of the micro-focusing unit layer, the transparent spacer layer and the graphic structure layer will be greater than the aperture of the micro-focusing element; 2. There is no limit The positional coordinate relationship between the microlens array and the microtext array located on the first surface of the substrate. From a scientific point of view, in many cases, this structure will not produce a moiré image

The third is that when the element is used, people observe the enlarged micro-graphic image from the side of the micro-lens unit layer. When the surface micro-lens array is covered by transparent foreign objects such as water, the focusing micro-lens will no longer function. In actual use a great inconvenience

[0011] The overall thickness of this kind of imaging film is generally relatively large, which may cause the imaging film to be difficult to cut during hot stamping
