Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with test examples and specific embodiments. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0024] 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 image elements. At the viewing distance l, the horizontal viewing angle θ of the traditional integrated imaging 3D display is:

[0025]

[0026] Among them, p is the horizontal pitch of the image elements, g is the distance between the pinhole array and the 2D display screen, m is the number of image elements in the horizontal direction of the micro-image array, and w is the aperture width of the pinholes. In conventional integrated i...

Abstract

The invention discloses an integrated imaging 3D display device based on a pinhole array with a gradual pitch, including a 2D display screen for displaying a micro-image array and a pinhole array with a gradual pitch. In the pinhole array with a gradual pitch, The pinholes in the same column have the same horizontal pitch; the pinholes in the same row have the same vertical pitch, and the horizontal pitch gradually increases from the center of the row to the edge of the row; the horizontal and vertical pitches of the picture elements in the micro-image array The pitches are the same as the horizontal and vertical pitches of their corresponding pinholes, respectively. When the integrated imaging 3D display device based on the gradual pitch pinhole array is used for imaging, the horizontal viewing angle has nothing to do with the number of image elements in the micro image array, so that the horizontal viewing angle of the integrated imaging 3D display device can be 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 ...
