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 integrated imaging 3D liquid crystal display and an optical device used therefor. The integrated imaging 3D liquid crystal display comprises: a lens array, a display panel, and a dimming panel interposed between the lens array and the display panel , wherein the dimming panel includes a plurality of dimming units corresponding to different lenses or combinations of the lens array, the dimming unit has no displacement relative to the lens array and the display panel during operation, and includes electrodes and dimming The optical material, the electrode is applied with voltage, so that when the light adjusting material transmits the light from the display panel to the lens array, it changes the transmission direction of the light. The viewing angle of the integrated imaging 3D liquid crystal display can be increased.

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...
