Embodiment

[0036] The selection of electric birefringent material: described birefringent material selects blue phase liquid crystal for use, its refractive index gets by formula 9 when not adding electric field: n (0)=1.5433, when applied electric field is E=1.95111V / μm, Δn=0.1650 tends to saturation. According to the above formula (1-9), it can be calculated that the realized maximum beam splitting angle is 19°.

[0037] Using a 40-inch polarized display with a resolution of 1920×1080, the number of microlens arrays produced by the hot-melt method is 1920×1080, the diameter of each lens is 0.5mm, and the focal length of the lens element is required to be between 0.25mm-2.5mm Between, here, we choose f = 2mm,. A Wollaston prism with a size of 0.5 mm and a beam splitting angle S=60° is placed next to the collimator lens array. The angle between the two left and right viewing angles formed ranges from 0° to 19°, and the binocular distance of the observer is 65mm. According to Among th...

Abstract

The invention discloses a naked-eye three-dimensional display method and device based on a parallax error. Compared with a conventional parallax-error naked-eye three-dimensional display technology based on a cylindrical mirror and a fence, the method and device are characterized in no resolution loss, no display brightness reduction and continuous multiple view angles. The method comprises the steps: enabling parallax error images, which are outputted by a polarization display, respectively left and right view angles, and also have mutually vertical polarization states, to pass through a wollaston prism array made of electric birefringence materials, thereby enabling the images with different polarization states to be emergent at a specific inclination angle, and forming left and right parallax error images. The inclination angle is adjusted through the change of the refractive index of the electric birefringence materials, and human eyes observe the two parallax error images at the same time, thereby forming a three-dimensional image in a head. The device based on the above method comprises a polarization display, a collimating lens array, and the wollaston prism array made of electric birefringence materials.

Description

technical field [0001] The invention belongs to the technical field of naked-eye three-dimensional display. The method and its device utilize the principle of parallax to realize naked-eye three-dimensional display without loss of image resolution and brightness. Compared with the existing parallax naked-eye 3D display technology based on cylindrical mirrors and barriers, it has the characteristics of no loss of resolution, no reduction in display brightness, and continuous multi-view angles. Background technique [0002] Three-dimensional stereoscopic display can reflect the three-dimensional world more truly. Mature flat-panel display technology is the preferred implementation solution for three-dimensional display technology at present. Most of the existing three-dimensional display technologies based on flat-panel displays are based on parallax technology. The left and right images with parallax are respectively transmitted to the left and right eyes of the viewer. Since...
