Double-vision 3D display device based on microlens array and polarization grating

Abstract

The invention discloses a double-vision 3D display device based on a microlens array and a polarization grating. The double-vision 3D display device comprises a display screen, the polarization grating, a pinhole array, the microlens array, polarized glasses I and polarized glasses II; a micro image array is composed of an image element I and an image element II, which are arranged in a horizontaldirection at intervals; the polarization grating is composed of a polarization unit I and a polarization unit II, which are arranged at intervals, and the polarization direction of the polarization unit I is orthogonal to the polarization direction of the polarization unit II; the horizontal pitches of all pinholes are the same, the vertical pitches of all pinholes are the same, the horizontal aperture widths of all pinholes are the same, the vertical aperture widths of all pinholes are the same, and a product of a ratio of the horizontal pitch to the vertical pitch of each pinhole and a ratio of the horizontal aperture width to the vertical aperture width is equal to a ratio of a horizontal width to a vertical width of the pinhole array.

Description

technical field [0001] The present invention relates to 3D display, and more specifically, the present invention relates to a dual-view 3D display device based on a microlens array and a polarization grating. Background technique [0002] Integrated imaging dual-view 3D display is the fusion of dual-view display technology and integrated imaging 3D display technology. It can make viewers see different 3D images in different viewing directions. [0003] In the traditional integrated imaging dual-view 3D display based on polarization grating: [0004] (1) The micro image array contains two groups of image elements, and the two groups of image elements are arranged alternately in the horizontal direction. [0005] (2) The two groups of image elements are all square, that is, the horizontal pitches of the two groups of image elements are equal to the vertical pitches. [0006] (3) The pinholes corresponding to the two groups of image elements are all square, and the horizonta...

Problems solved by technology

Its disadvantage is that the pixels of a single 3D image in the integrated imaging dual-view 3D display are equal to half of the pixels of a single 3D image in the integrated imaging 3D display

Its disadvantage is that the pixels of a single 3D image in the integrated imaging dual-view 3D display are equal to half of the pixels of a single 3D image in the integrated imaging 3D display

Therefore, the uneven distribution of 3D pixels affects the viewing effect

The total number of individual 3D image pixels in the integrated imaging dual-view 3D display is small, and the few 3D pixels in the horizontal direction affect the viewing effect
