Trends and Vision
Next generation displays will be 3D
Black&White Colour High Definition TV
A paradigm shift in visualization
The market is waiting for a real solution
3D data is already there, but lost while displaying
3D Display Technologies
Background
3D images contain more information than 2D
Stereoscopic: 2x (L+R)
Multiview: ~8-16x
Volumetric: 20-200 slices
True 3D: continous (~100x)
Total number of beams law, points/sec rate
Determine the quality of any 3D solution
Direction selective light emission
Common for all 3D systems having a screen
Fundamentals
Vertical / horizontal parallax
Reduce the number of beams by omitting vertical parallax
Different horizontal and vertical angular resolution
The HoloVizio System
Optical modules
Project light beams to the points of the screen from various angles
Holographic screen
Direction selective property with angularly dependent diffusion characteristics
Emission angle geometry determined
The screen performs the necessary optical transformation, but makes no principal change in directions
No optical road-blocks like at parallax barrier, lenticular lenses
HOLOVISION project
To realize a >100x capacity jump of current displays
real technology challenge
to build a no-compromise display
a milestone towards Gigapixel displays
To realize a novel principle
combination of spatial and time multiplexing
to fully exploit component capabilities
To use latest available technologies and components
Hi-res microdisplays, LEDs
World’s first 100 MPixel 3D display
