Abstract

The invention provides a multi-focal plane display system and device. The system comprises a laser projection light engine and a holographic reflected light fusion device. The laser projection light engine generates and modulates at least two laser light beam groups, and transmits the laser light beam groups to the holographic reflected light fusion device; each laser light beam group correspondsto one display image; the holographic reflected light fusion device reflects the at least two laser beam groups; the pupil exiting positions of the laser beam groups are the same, and a display imagewith at least two focal planes is obtained after that imaging by the human eyes of the laser beam groups. The multi-focal plane display system is simple in structure and easy to realize.

Description

technical field [0001] The embodiments of the present application relate to the field of display technology, and in particular, to a multi-focal plane display system and device. Background technique [0002] Augmented Reality (Augmented Reality, AR) is a technology that increases users' perception of the real world through the information provided by the computer system, applies virtual information to the real world, and superimposes computer-generated virtual objects and scenes on the real scene, thereby Realize the augmentation of reality. Virtual reality (Virtual Reality, VR) is to use the information provided by the computer system to generate a virtual world, for example, virtual objects and scenes can be presented. [0003] Currently, the vergence-accommodation conflict is the biggest technical problem in AR and VR, seriously affecting user experience. Among them, the visual vergence-accommodation conflict refers to the inconsistency of the distance information of th...
