Problems solved by technology

As an ideal 3D display technology, light field is obviously different from traditional 2D display: traditional 2D display can only provide psychovisual information such as affine, occlusion, light and shadow, texture, etc.

Abstract

The invention discloses a polymer dispersed liquid crystal film and a light field display system and method. The polymer dispersed liquid crystal film is a transmission-type polymer dispersed liquid crystal film prepared from nematic phase liquid crystal E7 and an ultraviolet photosensitive monomer NOA65 in a mass ratio of 55: 45 through a polymer induced phase separation PIPS method. The high-resolution light field display system based on the polymer dispersed liquid crystal film comprises a backlight source, a display panel, a microlens array and the polymer dispersed liquid crystal film. According to the invention, parallel light emitted by the backlight source reaches the display panel and then illuminates the element image array on the display panel, and the parallel light is further converged through the microlens array and finally enters the polymer liquid crystal film, so that reconstruction display of three-dimensional image points is realized.

Description

technical field [0001] The disclosed invention relates to the field of three-dimensional display, in particular to a polymer-dispersed liquid crystal film, a high-resolution light field display system and a light field display method based on the polymer-dispersed liquid crystal film. Background technique [0002] In the real world, the human eye sees objects in space as three-dimensional, while traditional display technologies can only provide two-dimensional flat image display, lacking depth information, which does not conform to the visual habit of human eyes viewing three-dimensional objects. When the human eye looks at objects at different distances, the ciliary muscle in the eyeball will adjust the shape of the lens to focus the image of the object on the retina. At the same time, the two eyeballs will turn inward when looking at near objects, The object will rotate outward when it is in contact with it. This phenomenon is called the convergence effect. Focus and verg...
