Title:
WEARABLE DISPLAY DEVICE AND PROJECTION DEVICE
Document Type and Number:
Japanese Patent JP2023070107
Kind Code:
A
Abstract:
To provide a wearable display device and a projection device.SOLUTION: A wearable display device includes an optical waveguide element and a projection device. The projection device includes an optical device main body, at least one light-emitting unit, a light mixing unit, and a projection lens. The optical device main body includes at least one positioning structure. The light-emitting unit is connected to the optical device main body and is used to emit an illumination light flux. The light mixing unit is disposed inside the optical device main body and is positioned by the positioning structure. The light mixing unit exists in a propagation route of the illumination light flux and is used to guide the illumination light flux to generate a video light flux. The projection lens is connected to the optical device main body, and the projection lens exists in a propagation route of the video light flux and is used to project the video light flux to the optical waveguide element.SELECTED DRAWING: Figure 4
