Abstract
The invention provides an augmented reality integrated imaging 3D display device formed by a micro display screen, a micro lens array, a convex lens, and a light-splitting prism. The micro display screen displays a micro image array. The micro image array and the micro lens array reconstruct a micro 3D image. The micro 3D image forms a magnified 3D virtual image in space after passing the convex lens and the light-splitting prism. The micro 3D image and the 3D virtual image are superposed in space so as to achieve augmented reality integrated imaging 3D display.
