Blue-phase-liquid-crystal-microlens-array-based integrated imaging display device

Abstract

The invention provides a blue-phase-liquid-crystal-microlens-array-based integrated imaging display device. The blue-phase-liquid-crystal-microlens-array-based integrated imaging display device comprises image display equipment and a blue-phase liquid crystal microlens array, wherein the image display equipment is used for displaying a 2D (Two-Dimensional) image or a micro-image array and is placed at a position a certain distance behind the blue-phase liquid crystal microlens array, and the centers of the image display equipment and the blue-phase liquid crystal microlens array are aligned. When an appropriate drive voltage V0 is applied to the blue-phase liquid crystal microlens array and the image display equipment displays the 2D image, the blue-phase-liquid-crystal-microlens-array-based integrated imaging display device realizes 2D display; when an appropriate drive voltage unequal to V0 is applied to the blue-phase liquid crystal microlens array and the image display equipment displays the micro-image array, the blue-phase-liquid-crystal-microlens-array-based integrated imaging display device realizes integrated imaging 3D (Three-Dimensional) display; and the improvement on the integrated imaging display performance can also be achieved through reasonably setting and regulating the drive voltage of the blue-phase liquid crystal microlens array of the blue-phase-liquid-crystal-microlens-array-based integrated imaging display device.

Description

Technical field [0001] The present invention relates to display technology, more specifically, the present invention relates to an integrated imaging display technology, especially an integrated imaging display technology based on a blue phase liquid crystal microlens array. Background technique [0002] Integrated imaging is a technology that uses a microlens array to record and reproduce three-dimensional (3D) scenes. It includes two processes: shooting and displaying. During the shooting process, a microlens array composed of many lens elements arranged in parallel in the horizontal and vertical directions is used to obtain the stereo information of the 3D scene, and the stereo information is recorded on the image recording device located at the focal plane of the microlens array to obtain the image elements , All image elements are arranged in parallel in the horizontal and vertical directions to form a micro image array. The micro lens array used in the display process and ...
