Full-time, full-resolution autostereoscopic flat panel
display
This solution is designed for flat-panel displays, like CRTs.
Some components are similar to those used in our CRT-based system, and provide
the full freedom of movement with no mechanical latency. Most important, though,
this display's unique construction provides the following additional advantages:
- The display is neither spatially nor temporally multiplexed. Each eye sees the entire screen at all
times - no eyewear is required. You just see rock-solid 3D at the full native
resolution of the display for each eye.
- Using a subset of the autostereoscopic design, we can build a
less-expensive, passive-glasses-based, stereoscopic display. Although
requiring lightweight glasses, it provides the same full-time, full-resolution
display as the autostereoscopic version. Thus, unlike systems
based on pi-cell shutters, there is full resolution with no flickering
whatsoever (i.e., the user sees the entire screen with both eyes all the
time). The advantage of using the passive glasses on this display, is that
multiple users can view the display simultaneously.
- We can use a variation of this technology to provide a stereoscopic projection system (using passive polarizing glasses) where only one projector is required. Again, this system provides full resolution of each image in the stereo
pair and no time-sharing (i.e., no flicker).
- A hybrid display can be switched from autostereoscopic to
stereoscopic mode (using passive glasses) at the flip of a switch. The
principle user can work in autostereoscopic mode until s/he's produced
something to show others. A switch is flipped, the spectators don passive
polarizing glasses, and everyone sees in full-resolution, non-flickering
stereo.
Further technical details are available in the paper
presented at the 2003 Stereoscopic Displays and Applications conference.
