Embodiment 1

[0029] The present invention provides a wide viewing angle integrated imaging 3D display device, which increases the horizontal width of the common area where all image elements reconstruct the 3D viewing area, and realizes wide viewing angle integrated imaging 3D display.

[0030] and see figure 1 The shown traditional polarization grating-based crosstalk-free integrated imaging 3D display device, wherein the first polarization grating 4 makes the light passing through it become polarized light with different polarization directions, and the second polarization grating has a modulation effect on polarized light, Each image element 3 on the 2D display screen 1 reconstructs a 3D scene through the pinhole corresponding to the image element, and the image elements in other columns cannot pass through the pinhole, thereby realizing crosstalk-free integrated imaging based on polarization gratings 3D display.

[0031] At the viewing distance l, the horizontal viewing angle θ of the...

Abstract

The invention discloses a wide-viewing-angle integral imaging 3D display apparatus. Horizontal pitches of pin holes in any row of a pinhole array with gradually-varied aperture are the same, the horizontal aperture width of the pinholes in the pinhole array with the gradually-varied aperture is gradually increased from the middle to the two sides, and the horizontal width of a reconstruction 3D vision area of an image primitive in a micro-image array is gradually increased from the middle to the two sides via the pinholes in the pinhole array with the gradually-varied aperture so that the horizontal width of a public area of all the image primitive reconstruction 3D vision areas is increased, and the integral imaging 3D display visual angle is wider than the display visual angle of a non-crosstalk integral imaging 3D display apparatus based on polarization grating in the prior art.

Description

technical field [0001] The present invention relates to integrated imaging 3D display, more specifically, the present invention relates to a wide viewing angle integrated imaging 3D display device. 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. [0003] Such as figure 1 As shown, in the traditional crosstalk-free integr...
