Abstract

The invention discloses an integrated imaging 3D display device based on a gradient pitch pinhole array. The integrated imaging 3D display device based on the gradient pitch pinhole array comprises a 2D display screen used for displaying a micro image array and the gradient pitch pinhole array, wherein pinholes in the same column in the gradient pitch pinhole array has the same horizontal pitch; pinholes in the same row are the same in vertical pitch, and the horizontal pitches are gradually increased from the center to row edges; the horizontal and vertical pitches of image primitives in the micro image array are respectively the same as the horizontal and vertical pitches of the corresponding pinholes. When the integrated imaging 3D display device based on the gradient pitch pinhole array is used for imaging, a horizontal view angle is unrelated to the image primitives in the micro image array, so that the horizontal view angle of the integrated imaging 3D display device is increased.

Description

technical field [0001] The invention relates to an integrated imaging 3D display, in particular to an integrated imaging 3D display device based on a pinhole array with a gradual pitch. Background technique [0002] Integrated imaging 3D display technology is a true 3D display technology that does not require any visual aids. This technology has the characteristics of viewing with naked eyes, its recording and display process is relatively simple, and it can display stereoscopic images with full parallax and full true color. It is one of the hot technologies in the current 3D display technology. However, the current integrated imaging 3D display device still has shortcomings such as narrow viewing angle, which limits its practical application. [0003] like figure 1 As shown, in a conventional integrated imaging 3D display, the viewing viewport is a common part of the imaging area of ​​all picture elements. At the viewing distance l, the horizontal viewing angle θ of the ...
