Title:
FRONT-PROJECTED HOLOGRAPHIC DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/004954
Kind Code:
A1
Abstract:
A front-projected holographic display apparatus (1), comprising a support table (100), an image unit (200), an imaging system and a control system. The image unit (200) comprises a first holographic image screen (210), a second holographic image screen (220) and a third holographic image screen (230), wherein the first holographic image screen (210), the second holographic image screen (220) and the third holographic image screen (230) are arranged on the support table (100); and the first holographic image screen (210) and the second holographic image screen (220) are connected to each other and arranged at a certain angle, and the second holographic image screen (220) and the third holographic image screen (230) are connected to each other and arranged at a certain angle. The imaging system is used for projecting an image onto the image unit (200). The control system is used for controlling the projection of the imaging system. The imaging system can project a holographic image onto the first holographic image screen (210), the second holographic image screen (220) and the third holographic image screen (230), so that a user can view the images on the first holographic image screen (210), the second holographic image screen (220) and the third holographic image screen (230) at the same time, thereby realizing image viewing from multiple angles without distortion.
