Integrated imaging 3D display device based on two-dimensional inclined column lens array

Abstract

The invention discloses an integrated imaging 3D display device based on a two-dimensional inclined column lens array. The integrated imaging 3D display device comprises a 2D display panel, an inclined column lens array I and an inclined column lens array II, wherein the planar surface of the inclined column lens array I is tightly adhered to the 2D display panel; the optical distance between the inclined column lens array I and the 2D display panel is the same as the focal length of the inclined column lens array I; the convex surface of the inclined column lens array I faces outwards; the convex surface of the inclined column lens array II is adhered to the convex surface of the inclined column lens array I; the planar surface of the inclined column lens array II faces outwards; the inclination angles of the two inclined column lens arrays relative to the 2D display panel are different, so that the pitches of lens units are matched with the size of the pixel of the 2D display panel, and the purpose of eliminating moire fringes is achieved. On premise that the cost of the integrated imaging 3D display device is reduced, the moire fringes of the integrated imaging 3D display device are reduced, and meanwhile the horizontal watching view and the vertical watching view of the integrated imaging 3D display device are increased.

Description

technical field [0001] The invention relates to an integrated imaging 3D display technology, more specifically, the invention relates to an integrated imaging 3D display technology based on a two-dimensional inclined cylindrical lens array. Background technique [0002] Integrated imaging 3D display technology can reconstruct 3D scenes with full parallax and true color, and is a true 3D display technology without auxiliary equipment. [0003] Integrated imaging 3D display technology is divided into two processes: shooting and displaying: in the shooting process, the stereo information of the 3D scene is recorded on the photosensitive device through the microlens array to generate a micro image array; in the display process, the integrated imaging 3D display device uses the microlens The array or two-dimensional orthogonal cylindrical lens array displays the micro-image array, and reconstructs the stereoscopic image of the 3D scene captured in space according to the reversibl...

AI Technical Summary

Problems solved by technology

However, when the parameters of the 2D display panel and the cylindrical lens array are determined, the integrated imaging 3D display device based on the two-dimensional cylindrical lens array has the problem that the pitch of the lens unit does not match the pixel size of the 2D display panel, which will lead to serious moiré fringes. Seriously affect the stereoscopic reconstruction effect of 3D scenes
