Embodiment

[0027] see figure 1 , in the existing integrated imaging 3D display devices based on pinhole arrays, the light emitted by a picture element 3 on the 2D display screen 1 passes through its corresponding pinholes to form a normal 3D image (such as figure 1 Mark 4 in the middle); However, part of the light emitted by the image element 3 adjacent to the image element 3 in the horizontal direction also passes through the pinhole, causing crosstalk between adjacent image elements 3 in the horizontal direction (such as figure 1 6), thereby reducing the imaging area of ​​each image element 3, wherein the actual imaging area of ​​a single image element 3 is as figure 1 Mark 5 shows. another example figure 2 As shown, in the existing integrated imaging 3D display device based on pinhole array, the viewing area is the common part of the imaging area of ​​all image elements 3, at the viewing distance l, the existing integrated imaging based on pinhole array The horizontal viewing angl...

Abstract

The invention discloses a wide-visual-angle integrated imaging 3D display device based on barrier and pin hole arrays. The barrier array is disposed between a 2D display screen and the pin hole array, thereby enabling the light from each image element to just form an image through the corresponding pin hole, avoiding the crosstalk of adjacent image elements in a horizontal direction, enlarging the imaging region of each image element, and enabling the view angle of the display device to be larger. Furthermore, the device does not need to reduce the horizontal diameter of the pin hole or reduce the number of the image elements in a miniature image array so as to enlarge the view angle. Therefore, the display device can achieve the visual-angle integrated imaging 3D display under the condition that the optical efficiency and resolution are not reduced.

Description

technical field [0001] The invention relates to an integrated imaging 3D display device, in particular to a wide viewing angle integrated imaging 3D display device based on barrier ribs and pinhole arrays. Background technique [0002] The integrated imaging 3D display device uses the reversible principle of the optical path to record the stereoscopic information of the 3D scene on the image recording device through a pinhole array or a microlens array to generate a micro-image array, and then display the micro-image array on a 2D display screen. A stereoscopic image of the original 3D scene is reconstructed through a pinhole array or a microlens array. Compared with the integrated imaging 3D display device based on microlens array, the integrated imaging 3D display device based on pinhole array has the advantages of low cost, small weight, thin device thickness and no limitation of manufacturing process. [0003] However, in the existing integrated imaging 3D display devic...
