Title:
OPTICAL EMISSION MODULE, OPTICAL DISPLAY DEVICE, TERMINAL DEVICE, AND IMAGE DISPLAY METHOD
Document Type and Number:
WIPO Patent Application WO/2023/193210
Kind Code:
A1
Abstract:
An optical emission module, an optical display device, a terminal device, and an image display method, used for solving the technical problem of an increase in the size of a head-up display (HUD) device when the HUD device generates virtual images of different focal planes, and applied to the fields of optical display or manual driving, etc. The optical emission module comprises: a first light source assembly used for emitting a first light beam and a second light beam. The N reflective areas of a transmissive assembly are used for reflecting the first light beam to a first reflective assembly, and the first reflective assembly is used for reflecting the received first light beam to a second reflective assembly; the M transmissive areas of the transmissive assembly are used for transmitting the second light beam to the second reflective assembly; the second reflective assembly is used for reflecting the first light beam from the first reflective assembly to a first diffusion assembly, forming a first image on the first diffusion assembly by means of rotation, reflecting the second light beam from a transmissive area of a transflective assembly to a second diffusion assembly, and forming a second image on the second diffusion assembly by means of rotation.
