Optical imaging display system and near-eye display equipment

Abstract

The invention provides an optical imaging display system and near-to-eye display equipment. The optical imaging display system can be applied to the near-to-eye display equipment. The optical imaging display system comprises an image acquisition and processing module and an optical display module, wherein the image acquisition and processing module comprises an image acquisition assembly and a first optical assembly; the optical display module comprises a micro-display and a first optical assembly. The first optical assembly comprises a polarizing beam splitter, a lens group, an optical coupling device and a polarizer of a second type. The image acquisition and processing module and the optical display module share the first optical assembly, so that the problem that the near-to-eye display equipment is large in size and weight due to the fact that the image acquisition and processing module and the optical display module are independently arranged is solved; moreover, the field angle of the image acquisition and processing module is consistent with that of the optical display module, so that the problem of size inconsistency when the virtual image and the real image of the near-to-eye display equipment are superposed is solved, and the quality of the image displayed to the user is improved.

Description

technical field [0001] The present application relates to the field of virtual reality display, and more specifically, to an optical imaging display system and a near-eye display device. Background technique [0002] Augmented reality (augmented reality, AR) and virtual reality (virtual reality, VR) technologies use near-eye display solutions to superimpose virtual images on real scenes and provide users with immersive and interactive experiences, which have become research hotspots in recent years. one. [0003] At present, AR equipment generally includes an image acquisition and processing module and an optical display module, and the two modules are set separately. Among them, the image acquisition and processing module mainly includes image acquisition components (including lenses and photoelectric sensors, etc.) and some optical devices. Used to collect image information of the real world. The optical display module mainly includes a microdisplay and some optical devi...

AI Technical Summary

Problems solved by technology

However, due to the relatively large volume of the image acquisition and processing module and the optical display module, the volume and weight of the AR device will increase

Moreover, since the image acquisition and processing module and the optical display module are set separately and each uses its own independent optical system, the field angles of the optical systems of the two modules may be inconsistent, which may cause the image acquisition and processing module and the optical display The problem of inconsistency in the field of view of the module leads to inconsistency in size when the virtual image and the real image are superimposed, resulting in poor image quality displayed by the AR device and reducing user experience
