Near-eye display system

Abstract

The invention provides a near-eye display system which comprises an image display device, a light beam deflection device and an array imaging device. The array imaging device comprises at least two diffraction planes. The light beam deflection device enables modulated sub-image lights to be incident into incident angles of diffraction planes corresponding to the sub-image lights within the diffraction angle bandwidths of the corresponding diffraction planes and enables the modulated sub-image lights to be incident to the incident angles of the diffraction planes non-corresponding to the sub-image lights outside the diffraction angle bandwidths of the non-corresponding diffraction planes. The diffraction plane reflects and converges the sub-image lights of which the respective incident angle is within the diffraction angle bandwidth to form to-be-displayed sub-images in human eyes. After the image display device outputs all the sub-image lights of the to-be-displayed image, the to-be-displayed sub-images formed in the human eyes can be spliced into the to-be-displayed image in user vision. The near-eye display system has the characteristics of large field of view and high resolutionratio and is smaller in size compared with a near-eye display system with a traditional visual optical system.

Description

technical field [0001] The present invention relates to the technical field of augmented reality, in particular, to a near-eye display system. Background technique [0002] Augmented Reality (AR, Augmented Reality) is a technology that uses virtual objects or information to augment real scenes, and is widely used in scientific research, military, industry, games, video, education and other fields. At present, the mainstream near-eye display system applied to augmented reality generally uses a micro image display as the image source, and cooperates with the traditional visual optical system to realize the enhanced display. Limited by the existing technology and process level, it is difficult to improve the resolution of the micro image display. Moreover, the display field of view of a traditional visual optical system is closely related to the volume of the visual optical system. As the display field of view is increased, the volume of the visual optical system will increas...
