Full-time full-resolution dual stereoscopic/autostereoscopic display or rock-solid 3D on a flat screen: with glasses or without!

Abstract

A stereoscopic or autostereoscopic display based on this technology provides full resolution and freedom of movement, but with no flicker. Simply put, the display is neither spatially nor temporally multiplexed. It sounds unbelievable, but it's true -- an autostereoscopic display where each eye sees every displayable pixel on the screen at all times. This technology is designed for flat-panel displays, such as LCDs and has the following characteristics: (1) The display is not spatially multiplexed. Each eye sees the full native resolution of the entire screen. (2) The display is not temporally multiplexed. The image for each eye is visible continuously, i.e., at all times. (3) In its simplest form, this technology provides a full-time, full-resolution stereoscopic display for multiple viewers wearing passive polarizing glasses. (4) A variation of this technology can be used to make a full-time, full-resolution stereoscopic projection system for viewers wearing passive polarizing glasses using just a single projector. (5) With the addition of a dynamic aiming mechanism, and an adjustment in the display's output, we can create a single-user, full-time, full-resolution autostereoscopic display requiring no glasses and providing full freedom of movement. Software applications can use the same information about viewwer position to provide natural, full "look-around." (6) A hybrid version of the display can alternate between autostereoscopic (single-user, no glasses) and stereoscopic modes (multi-user, passive glasses).
