AI Technical Summary

Technical Problem

Optical modules in existing AR devices are difficult to balance between achieving high image quality, low power driving and miniaturization, resulting in limited equipment performance and service life.

Method used

By designing an optical member including a housing, a lens module, a first reflective member, a second reflective member and a emitting member, the design of the reflective member reduces the size and inclination of the second reflective member, and the angle and distance of the optical member are controlled to achieve low power driving and improved image quality.

Benefits of technology

Low power drive, improved image quality and miniaturization of optical components are achieved, extending the service life of the device and improving performance.

Abstract

An optical member according to an embodiment includes: a housing; a lens module disposed within the housing; a first reflecting member that reflects light emitted from the lens module; a second reflecting member that reflects the light reflected from the first reflecting member; and an emission member through which the light reflected from the second reflection member is emitted. The light reflected by the second reflective member passes through the first reflective member and travels to the emission member.
