3D display device based on gradient aperture rectangular pinhole array

Abstract

The invention discloses a 3D display device based on a gradient aperture rectangular pinhole array. The 3D display device comprises a backlight source, the gradient aperture rectangular pinhole arrayand a display screen. The gradient aperture rectangular pinhole array comprises a plurality of groups of one-dimensional rectangular pinholes and a plurality of groups of two-dimensional rectangular pinholes. Each one-dimensional rectangular image element corresponds to a plurality of one-dimensional rectangular pinholes, and the plurality of one-dimensional rectangular pinholes are horizontally symmetrical by taking the center of the one-dimensional rectangular image element as the center. Each two-dimensional rectangular image element corresponds to a plurality of two-dimensional rectangularpinholes, and the plurality of two-dimensional rectangular pinholes are horizontally symmetrical by taking the center of the two-dimensional rectangular image element as the center. A plurality of one-dimensional 3D images are reconstructed by using the one-dimensional rectangular image elements corresponding to the light illumination emitted by the plurality of one-dimensional rectangular pinholes, and reconstructing a plurality of two-dimensional 3D images by using the two-dimensional rectangular image elements corresponding to the light illumination emitted by the plurality of two-dimensional rectangular pinholes. The plurality of one-dimensional 3D images and the plurality of two-dimensional 3D images are combined into a high-resolution 3D image in a viewing area.

Description

technical field [0001] The present invention relates to 3D display, and more specifically, the present invention relates to a 3D display device based on a rectangular pinhole array with variable aperture. Background technique [0002] 3D display based on integrated imaging, referred to as integrated imaging 3D display, is a true 3D display. Compared with visual aid / grating 3D display, it has significant advantages such as no stereoscopic viewing fatigue; compared with holographic 3D display, it has the advantages of relatively small data volume, no coherent light source and no harsh environmental requirements. Therefore, integrated imaging 3D display has become one of the cutting-edge 3D display methods in the world, and it is also the most promising naked-view 3D display method for 3D TV. However, the bottleneck problem of insufficient 3D resolution seriously affects the experience of viewers, thus restricting the wide application of integrated imaging 3D displays. In add...
