Document Type and Number:
WIPO Patent Application WO/2024/051777
Kind Code:
A1
Abstract:
A near-eye display optical machine (10) and a near-eye display apparatus (1). The near-eye display optical machine (10) is used for projecting an image light to a waveguide device (20), so as to achieve near-eye display, and the near-eye display optical machine (10) comprises an image source assembly (11), an imaging assembly (12) and a deflection prism group (13). The imaging assembly (12) is arranged at a light-emitting side of the image source assembly (11), and is used for modulating an image light, which is emitted by means of the image source assembly (11), to form an image; and the deflection prism group (13) is movably arranged at an imaging side of the imaging assembly (12), and is used for deflecting the image light, which is modulated by the imaging assembly (12), so as to adjust an emergent direction and angle of the image light such that same is coupled into the waveguide device (20).
