Title:
AUGMENTED REALITY DISPLAY OPTICAL DEVICE, OPTICAL SYSTEM, GLASSES AND HUD DISPLAY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/190060
Kind Code:
A1
Abstract:
Disclosed is an augmented reality display optical device (10), an augmented reality display system (20) having the augmented reality display optical device (10), augmented reality display glasses (30), and an augmented reality HUD display system (40, 50). The augmented reality display optical device (10) comprises a substrate layer (200) and a micro-nano optical reflection layer (100), wherein the substrate layer (200) comprises a first surface (210) and a second surface (220) opposite the first surface (210); the substrate layer (200) transmits ambient light; the micro-nano optical reflection layer (100) is arranged on the first surface (210) of the substrate layer (200); and the micro-nano optical reflection layer (100) is configured to reflect light of a virtual image in a preset narrow-band wavelength band. The augmented reality display optical device (10) uses the characteristics of the micro-nano optical reflection layer (100) having extremely high reflectivity for image light at a preset narrow wavelength and extremely high transmissivity for ambient light, thereby achieving high brightness and high transmissivity of the display system for a light source at the preset narrow wavelength with low cost and low power consumption.
