3-dimensional image display device and 3-dimensional image display equipment

A 3-dimensional image display device, comprising:

• a frame surrounding a viewing space;
• a projector-installing frame disposed behind the frame surrounding the viewing space;
• at least a first, second, and third image projector;
• at least a first, second, and third screen disposed within the frame, each of the screens having an inside surface facing the viewing space and an outside surface facing away from the viewing space, said first and second image projectors for projecting images onto the outside surfaces of said first and second screens respectively, and the third image projector for projecting images through the viewing space and onto the inside surface of said third screen;
• a controller for outputting image data for a 3-dimensional display according, respectively, from said first, second, and third image projectors to said first, second, and third screens;
• wherein the first projector is disposed behind one side of the projector-installing frame, and the third projector is fixed inside the projector-installing frame disposed behind the frame,
• wherein the images from said first image projector are projected through the projector-installing frame and directly onto said first screen:
• the images from said second image projector are projected onto said second screen through reflection by a reflective member disposed outside of the frame, and the images from said third image projector fixed inside the projector-installing frame are projected onto said third screen through reflection by another reflective member, and
• wherein at least one set of said image projectors and said screens includes a polarizing means for polarizing light, said polarizing means being disposed between said image projector and said screen,
• the first and third projectors being disposed behind a same side of the frame surrounding the viewing space.

A 3-dimensional image display equipment comprising:

• a mobile body having a closed space;
• a 3-dimensional image display device having frame installed in said closed space of said mobile body, the frame surrounding a viewing space;
• a projector-installing frame disposed behind the frame surrounding the viewing space,
• at least a first, second, and third image projector;
• at least a first, second and third screen disposed within the frame, each of the screens having an inside surface facing the viewing space and an outside surface facing away from the viewing space, said first and second image projectors for projecting images onto the outside surfaces of said first and second screens, respectively, and the third image projector for projecting images through the viewing space and onto the inside surface of said third screen;
• a controller for outputting image data for a 3-dimensional display, the image data adjusted to a left and a right eye of a viewer according, respectively, from said first and second image projectors to said first and second screens;
• wherein the first projector is disposed behind one side of the projector-installing frame, and the third projector is fixed inside the projector-installing frame disposed behind the frame,
• wherein the images from said first image projector are projected through the projector-installing frame and directly onto said first screen;
• the images from said second image projector are projected onto said second screen through reflection by a reflective member disposed outside of the frame, and the images from said third image projector fixed inside the projector-installing frame are projected onto said third screen through reflection by another reflective member, and
• wherein at least one set of said image projectors and said screens includes a polarizing means for polarizing light, said polarizing means being disposed between said image projector and said screen.

A 3-dimensional image display device, comprising:

• a frame surrounding a viewing space within which a viewer is positioned;
• a projector-installing frame disposed behind the frame surrounding the viewing space;
• at least a first, second, and third image projector;
• at least a first, second, and third screen disposed within the frame and correspondingly to said first, second, and third image projectors, said first, second, and third projectors for projecting first, second, and third images, respectively, onto the first, second, and third screens;
• a controller for outputting image data for a 3-dimensional display, the image data adjusted to a left and a right eye of a viewer according, respectively, from said first and second image projectors to said first and second screens;
• wherein the first projector is disposed behind one side of the projector-installing frame, and the third projector is fixed inside the projector-installing frame disposed behind the frame,
• wherein the first image from said first image projector is projected through the projector-installing frame and directly onto said first screen;
• the second image from said second image projector is projected onto said second screen through reflection by a reflective member disposed outside of the frame, and the third image from said third image projector fixed inside the projector-installing frame is projected onto said third screen through reflection by another reflective member;
• the 3-dimensional display device further comprising:
• liquid crystal shutter spectacles adapted to be worm by the viewer for perceiving a 3-dimensional image;
• a magnetic field generator operatively disposed on an upper cross beam of the frame above the viewing space for generating a magnetic field;
• and
• a magnetic-type position sensor operatively disposed within said liquid crystal shutter spectacles for outputting a position of the viewer relative to said first and second screens,
• wherein each of the three screens includes an inside surface facing the viewing space and an outside surface facing away from the viewing space.
