The present invention relates to a near-eye display device. The a near-eye display device includes a display, a first lens disposed in front of the display so as to be spaced apart from the display by a predetermined distance, a dynamic aperture adjustment element disposed adjacent to the first lens to dynamically control an aperture size of the first lens and a horizontal position of the aperture on a plane perpendicular to an optical axis, a main optics lens disposed to be spaced apart from the first lens by a predetermined distance, and a control system configured to control the dynamic aperture adjustment element.

An image display apparatus according to an embodiment of the present technology includes a plurality of projection units, a screen, and an image generation unit. The plurality of projection units projects image light corresponding to image data with reference to projection axes thereof and is disposed such that the projection axes face in directions different from each other along a first plane. The screen is disposed to intersect with the first plane at a first elevation angle (φ.sub.i) and diffuses and outputs the image light projected along the first plane at a second elevation angle (φ.sub.o) different from the first elevation angle (φ.sub.i). The image generation unit generates the image data for displaying a plurality of viewpoint images corresponding to viewpoints at which the screen is observed at the second elevation angle (φ.sub.o) on the basis of the directions of the projection axes on the first plane.

The present invention relates to the field of three-dimensional display technology, and more specifically, to a glasses-free light-field display method based on asymmetric light distribution of a projecting beam. In the method described in this patent application, beam projected by a pixel or a sub-pixel of a display device is guided to the corresponding pixel-viewing-zone or sub-pixel-viewing-zone of an asymmetric shape, by a corresponding modulation element. Based on these asymmetric pixel-viewing-zones or sub-pixel-viewing-zones, viewing zones for different pixel groups or sub-pixel groups are designed with different arrangement densities along different directions, to realize glasses-free light-field display with a reduced number of viewing zones. Time multiplexing is further introduced for presenting more viewing zones.
