Multilayer liquid crystal-based projection type three-dimensional display device and method

Abstract

The invention discloses a multilayer liquid crystal-based projection type three-dimensional display device. The three-dimensional display device comprises a backlight illumination system, a plurality of layers of liquid crystal display panels, a lens array and a directional scattering screen, which are sequentially arranged along the direction of an optical path, and also comprises a controller connected with each layer of liquid crystal display panel respectively. The invention also discloses a three-dimensional display method, which comprises the following steps of: resolving a three-dimensional scene required to be displayed into projected images, performing combination to form display images, transmitting the display images into each layer of liquid crystal display panel respectively, converging and projecting projected and displayed image sources which are products of pixel information of the liquid crystal display panels to the directional scattering screen by using corresponding lenses, and forming images at specified spatial positions. High-resolution three-dimensional display is realized by utilizing the superposition of the pixel information of the liquid crystal display panels.

Description

technical field [0001] The invention relates to the technical field of three-dimensional display, in particular to a projective three-dimensional display device and method based on multi-layer liquid crystal. Background technique [0002] The 3D display technology is very popular for its realistically providing stereoscopic information. In recent years, both academia and industry have invested heavily in the 3D display technology that can generate depth information. The existing commercial 3D display technology is mainly stereoscopic 3D display technology based on left and right eye parallax images. This technology can produce higher resolution parallax images, but the excessive viewing requirements and the useless auxiliary glasses limit the Its development, multi-view self-viewing 3D display technology based on barrier or lenticular lens has become the focus of current naked-eye 3D display research. Thanks to the rapid development of two-dimensional display unit arrays, t...

[0003] On the other hand, the multi-view splicing display scheme cannot ensure the continuity of the transition of viewing angles while taking into account the resolution of the displayed image, that is, it often cannot provide binocular parallax and motion parallax at the same time. For the naked-eye 3D display technology that many people watch at the same time, It is especially important to increase the spatial resolution of the display
