Abstract

The invention discloses a gradually-varied aperture pinhole array-based non-crosstalk integral imaging 3D display device, which comprises a 2D display screen and a gradually-varied aperture pinhole array, wherein the 2D display screen is used for displaying a micro-image array; horizontal and vertical central axes of the gradually-varied aperture pinhole array are correspondingly aligned at the horizontal and vertical central axes of the 2D display screen respectively; a first polarization grating is attached to the 2D display screen; a second polarization grating is attached to the gradually-varied aperture pinhole array; the first polarization grating and the second polarization grating are formed by tightly arranging a series of grid line units with the same sizes in the horizontal direction; each grid line unit only has one polarization direction; and the polarization directions of any two adjacent grid line units are intersected or opposite. The gradually-varied aperture pinhole array-based non-crosstalk integral imaging 3D display device provided by the invention aims at solving the crosstalk in the horizontal direction, so that a gradually-varied aperture pinhole array-based integral imaging 3D display device can be widely applied.

Description

technical field [0001] The invention relates to an integrated imaging 3D display, in particular to a crosstalk-free integrated imaging 3D display device based on a pinhole array with variable apertures. Background technique [0002] The integrated imaging 3D display device uses the reversible principle of the optical path to record the stereoscopic information of the 3D scene on the image recording device through a pinhole array or a microlens array to generate a micro-image array, and then display the micro-image array on a 2D display screen. A stereoscopic image of the original 3D scene is reconstructed through a pinhole array or a microlens array. Compared with the integrated imaging 3D display device based on microlens array, the integrated imaging 3D display device based on pinhole array has the advantages of low cost, small weight, thin device thickness and no limitation of manufacturing process. However, the optical efficiency of an integrated imaging 3D display devi...
