Embodiment Construction

[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0026] Integrated imaging technology is a true three-dimensional naked-view autostereoscopic display technology that uses microlens arrays to record and reproduce three-dimensional scenes. It includes two processes of acquisition and image reconstruction, its substrate principle, please refer to figure 1 , figure 1 It is a schematic diagram of the working principle of the integrated imaging technology in the prior art. In the acquisition stage, the light emitted by the recording object 130 passes through each lens 121 in the lens array 120, and the light passing through each lens 121 records a 2D image at the position corresponding to the sensor 110. , each 2D image is called an element image 140, and the element images 140 corresponding to all the lenses 120 form an element image array, and the element image array forms the information collection of...

Abstract

The invention discloses an integral imaging 3D liquid crystal display and optical equipment used by the same. The integral imaging 3D liquid crystal display comprises a lens array, a display panel and a dimming panel which is clamped between the lens array and the display panel, wherein the dimming panel comprises a plurality of dimming units corresponding to different lenses or combinations of the lens array, an electrode and a dimming material; the dimming units do not have displacement relative to the lens array and the display panel during the operation; the electrode is applied with voltage to ensure that the transmission direction of a light ray from the display panel is changed when the light ray is transmitted to the lens array by the dimming material. The angle of view of the integral imaging 3D liquid crystal display can be enlarged.

Description

technical field [0001] The invention relates to the technical field of 3D display, in particular to an integrated imaging 3D liquid crystal display and an optical device used therefor. Background technique [0002] Integrated imaging uses a microlens array to record a three-dimensional scene, and reproduces a 3D image through a microlens array with the same parameters. According to the reversible principle of the optical path, the 3D image reproduced has the same color, depth and other information as the original 3D scene, so integrated imaging is also called true 3D display. [0003] 3D viewing angle is an important performance parameter of integrated imaging 3D display. It refers to the viewing angle that can see a complete 3D image without cracks and jumps. The larger the 3D viewing angle, the greater the viewing freedom. [0004] At present, the industry generally adds a mechanically controlled movable grating (dynamic moving barrier) between the lens array and the disp...
