PANORAMIC VIEWING FIELD THREE-DIMENSIONAL DISPLAY APPARATUS

WIPO Patent Application WO/2011/020321

A1

A panoramic viewing field three-dimensional display apparatus comprises a high-speed projector (21), a rotatable reflector device and a cylindrical transmission directional diffusing screen (24). The optical axis of the high-speed projector (21), the rotation axis of the reflector device and the axis of the cylindrical transmission directional diffusion screen (24) are collinear. The image projected by the high-speed projector (21) is reflected by the reflector device to form image on the cylindrical transmission directional diffusion screen (24). The transmission directional diffusion screen (24) can control the diffusion angle of emergent light, so that the left eye and the right eye of a viewer can see the images with different visual angles to realize the three-dimensional display of a three-dimensional object on the panoramic viewing field. The panoramic viewing field three-dimensional display apparatus based on the high-speed projector (21) enables the eyes of the viewer to see images with binocular parallax at different positions, so as to realize the three-dimensional display.
