Sixty-four color LCD panels were employed to implement a natural 3D display. Sixty-four images displayed on the LCD panels are projected in the different horizontal directions by using modified 2D aligned telecentric optical systems. Because the projection angle pitch in the horizontal direction is as small as 0.33 degree, observers’ eyes can focus on the 3D images. Because the projection systems are telecentric, images are defocused little so that clear 3D images are generated in the 3D space. The horizontal viewing angle is 21.2 degrees, and the 3D screen size is 192 mm X 151 mm (9.6 inch.) The 3D objects can be displayed in the range of ~ 400 mm both in front of and behind the 3D screen. The prototype 3D display has following features: a) no need of wearing 3D glasses, b) simultaneous observation by multiple persons, c) no restriction on observing position, d) compatible with human 3D perception, e) providing high presence, and f) offering photorealistic and moving 3D images. The human accommodation responses to the prototype 3D display are very similar to those obtained for real 3D objects.
