Problems solved by technology
At present, mainstream augmented reality display technology is mainly based on head-mounted display (HMD) technology, which requires users to wear bulky display devices, and the user experience is poor; AR three-dimensional (3D) display is usually based on the principle of binocular parallax , in which the focus mismatch of binocular convergence will cause severe visual fatigue; real-time spatial positioning and image rendering delays will cause motion sickness and cause vertigo

Abstract
The invention provides a perspective three-dimensional display device based on a liquid crystal lens array. The device comprises a first polarizer, a scattering polarizer, a projector and the liquid crystal lens array, wherein a polarization direction of the first polarizer is a first direction; the scattering polarizer is located on a light emitting side of the first polarizer, the scattering polarizer is used for displaying an unit image array, the polarization direction of light emitted by the unit image array is a second direction, the second direction is vertical to the first direction, and polarized light of the first direction is allowed to pass through the scattering polarizer; the projector projects the unit image array to the scattering polarizer; and the liquid crystal lens array is located on the light emitting side of the scattering polarizer and is used for refracting the polarized light emitted by the unit image array so as to form a three-dimensional image, and the polarized light of the first direction is allowed to pass through the liquid crystal lens array. The design of the perspective three-dimensional display device based on the liquid crystal lens array is reasonable and a user experience is improved.
Description
technical field [0001] The invention relates to the field of display technology, in particular to a see-through three-dimensional display device and a three-dimensional display system based on a liquid crystal lens array. Background technique [0002] As the demand for providing three-dimensional stereoscopic images in animation display industries such as computer game industry, movie industry, etc. has increased, attempts have been made to provide practical 3D display devices capable of displaying three-dimensional animation images. In one approach to 3D imaging, two different two-dimensional (2D) images are presented to the viewer's left and right eyes. For example, a viewer views a pair of 2D images through each eye, and the 2D images are mixed in the viewer's brain so that a three-dimensional effect can be recognized. [0003] Augmented reality (AR) display technology is a display technology that superimposes and fuses virtual images rendered by display devices with rea...
