Title:
PROJECTION APPARATUS, DISPLAY DEVICE, VEHICLE AND PROJECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/032059
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a projection apparatus, a display device, a vehicle and a projection method, which can be mainly applied to a virtual image display scenario. The projection apparatus comprises an image source, a curved reflection unit and an optical element, wherein the image source is used for outputting imaging light; the curved reflection unit is used for reflecting the imaging light from the image source to the optical element; the optical element is used for reflecting the imaging light from the curved reflection unit to the curved reflection unit; the curved reflection unit is further used for reflecting the imaging light from the optical element to the optical element; the optical element is further used for transmitting the imaging light from the curved reflection unit; and a light reflection direction of the imaging light from the image source at a first reflection position on the curved reflection unit deflects in a first direction relative to a normal at the first reflection position, a light reflection direction of the imaging light from the optical element at a second reflection position on the curved reflection unit deflects in a second direction relative to a normal at the second reflection position, and the first direction is opposite to the second direction.
