Abstract

The invention discloses a stereo display capable of being watched by naked eyes. A high-resolution LCD video player provides a right group and a left group of images or videos arranged in parallel for a screen of the LCD video player, two convex lenses are placed in front of the screen of the player, an observer can watch the left and right images or videos by the left eye and the right eye through the convex lenses, a visual angle of the two eyes is amplified, two images are finally overlapped together in the brain of the observer through the automatic adjustment of the human eyes, and the observer generates the sense of watching stereo images. Some observers can directly observe the stereo images from the screen of the LCD video player by using the naked eyes; the high resolution, high brightness and high contrast of the screen of the LCD video player ensure that the observer can watch the high-quality stereo images through the naked eyes; and the stereo display has the advantages of simple structure and low manufacturing cost, is suitable for industrial production, and is particularly suitable for playing high-quality static or mobile stereo images on the LCD with the high resolution, high brightness and high contrast.

Description

technical field [0001] The invention relates to a stereoscopic display that can be viewed with naked eyes, and belongs to the technical field of stereoscopic display based on the principle of binocular parallax. Background technique [0002] In real life, all objects exist in the form of three-dimensional geometric entities. Ordinary flat-panel displays can only display flat images, and cannot produce a real natural three-dimensional look and feel. At present, the more mature stereoscopic display technology mainly uses binocular parallax to form stereoscopic vision images. Two cameras are used to simulate the left and right eyes to take two groups of photos or videos respectively, and then use a special eyepiece device to allow the left and right eyes to observe two groups of images. Group photos or videos, so the observer will stitch together a three-dimensional image in his mind. Commonly used binocular parallax stereoscopic display technologies mainly include "red-green...
