Abstract

The invention discloses an optically-controlled three-dimensional (3D) optical diaphragm and a preparation method thereof. The optically-controlled 3D optical diaphragm is attached onto any display device capable of displaying a three-dimensional image, and image information with parallax of a left eye and a right eye can be split to the left eye and the right eye of a person to form naked-eye free three-dimensional display. The optically-controlled 3D optical diaphragm comprises a transparent diaphragm material layer and a photochromic grid bar, wherein the transparent diaphragm material layer is doped with zinc oxide nano particles 1,8-diiodooctane additive, the photochromic grid bar is transparent under the non-ultraviolet radiation to display two-dimensional information, the photochromic grid bar turns mazarine under the ultraviolet radiation to realize the grating effect and display the three-dimensional information, through the zinc oxide nano particles in the transparent diaphragm material layer, the transmission rate of the transparent diaphragm material layer is increased by utilizing an optical principle, the viewpoint width of the 3D display is increased, the double-image of the 3D display can be reduced, the 1,8-diiodooctane additive optimizes the dispersibility and uniformity of the zinc oxide nano particles, and the 3D display effect is finally enhanced.

Description

technical field [0001] The invention relates to the technical field of 3D optical three-dimensional film, in particular to an optically controlled grating-type autostereoscopic display film and a preparation method thereof. Background technique [0002] With the continuous development of modern technology, people are no longer satisfied with the two-dimensional information displayed on the display screen. Three-dimensional stereoscopic display has developed in line with the needs of the times. Also getting higher and higher. [0003] Currently, there are two mainstream methods for realizing naked-eye three-dimensional display diaphragms: cylindrical lens diaphragms and grating diaphragms. Cylindrical lens diaphragms belong to low-light diaphragms, which are more complicated in process and higher in production cost. Once the production is completed, the parameters of the lens diaphragm are not easy to change, and it is difficult to realize the conversion between two-dimensio...
