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] Such as figure 1 As shown, in the existing 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] Wherein, p is the horizontal pitch of the image elements, f is the focal length of the lens elements, and m is the number of image elements in the horizontal direction of the micro-image array. In conventional integrated imaging 3D displays, the viewing angle is inversely proportional to the...

Abstract

The invention discloses an integrated imaging 3D display device based on a progressive pitch microlens array, which includes a display screen for displaying a micro image array and a progressive pitch microlens array. The horizontal pitch of the lens elements in the column is the same; the vertical pitch of the lens elements in the same row is the same, and the horizontal pitch gradually increases from the center of the row to the edge of the row; the horizontal pitch and vertical pitch of the image elements in the micro-image array The pitches are the same as the horizontal and vertical pitches of their corresponding lens elements, respectively. When the integrated imaging 3D display device adopts the micro-lens array with gradual pitch 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 present invention relates to an integrated imaging 3D display, in particular to an integrated imaging 3D display device based on a progressive pitch microlens array. 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] In integrated imaging 3D displays, the viewing viewport is the common part of the imaging area of ​​all image elements. Such as figure 1 As shown, at the viewing distance l, the horizontal viewing angle θ of the trad...
