ABSTRACT:
A three-dimensional display apparatus (10) for displaying true three-dimensional images that can be viewed without special three-dimensional eye glasses is disclosed. The apparatus includes a screen (12), a screen moving assembly (14) for moving the screen to a selected number of depth locations, and an imaging assembly (16) for displaying images on the screen as it is moved to its different depth locations. The imaging assembly includes a CRT (80) for successively generating the two-dimensional images as the screen is moved, a focusing system (82) for focusing the images from the CRT to the screen, and a control system (84) for driving the CRT. The control system includes a frame buffer processor (92) for receiving a signal representative of a three-dimensional image and for separating the signal into a number of two-dimensional images, an active pixels processor (94) for selecting only the active pixels for each image, and a graphics driver (96) responsive to the active pixels processor for turning on only the active pixels of the CRT for each two-dimensional image in synchronization with the back and forth movement of the projection screen.
