3D displays: toward holographic video displays of 3D images

Abstract

As the flat panel displays (Liquid Crystal Displays, AMOLED, etc.) reach near perfectionin their viewing qualities and display areas, it is natural to seek the next level of displays,including 3D displays. There is a strong surge in 3D liquid crystal displays as a result of thesuccessful movie Avatar. Most of these 3D displays involve the employment of special glasses thatallow one view perspective for each of the eyes to achieve a depth perception. Such displays are notreal 3D displays. In fact, these displays can only provide one viewing perspective for all viewers,regardless of the viewer's position. In addition, a fundamental viewing problem of focusing andaccommodation exist that can lead to discomfort and fatigue for many viewers. In this paper, theauthors review the current status of stereoscopic 3D displays and their problems. The authors willalso discuss the possibility of using flat panels for the display of both phase and intensity ofvideo image information, leading to the ultimate display of 3D holographic video images. Many of thefundamental issues and limitations will be presented and discussed.
