Integrated imaging 3D display device based on gradual-changing pitch micro lens array

Abstract

The invention discloses an integrated imaging 3D display device based on a gradual-changing pitch micro lens array. The integrated imaging 3D display device comprises a display screen used for displaying a micro image array and a gradual-changing pitch micro lens array, wherein in the gradual-changing pitch micro lens array, the horizontal pitch of lens units on the same row is the same; the perpendicular pitch of lens units on the same line is the same; the horizontal pitch is gradually increased from the center of the line to the edge of the line; the horizontal pitches and the perpendicular pitches of image units in the micro image array are separately the same as the horizontal pitches and the perpendicular pitches of the lens units corresponding to the image units. When the integrated imaging 3D display device based on the gradual-changing pitch micro lens array is used for imaging, the visual angle seen from a horizontal direction is independent of number of image units in the micro image array, so that the visual angle seen from the horizontal direction of the integrated imaging 3D display device is 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 gradually changing pitch microlens array. Background technique [0002] The integrated imaging 3D display technology is a true 3D display technology without any visual aids. This technology has the characteristics of naked eye viewing, its recording and display process is relatively simple, and it can display stereo images with full parallax and full true colors. It is one of the hotspot technologies in the current 3D display technology. However, the current integrated imaging 3D display device still has shortcomings such as a narrow viewing angle, which limits its practical application. [0003] In integrated imaging 3D display, the viewing area 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 traditional integrated im...
