- Quick Overview -
What is the DepthQ ® Polarization Modulator?
DepthQ ® is a sophisticated electronic switch that allows your audience to view 3D movies using
low-cost polarized glasses.
Works with your 3D-Ready DLP Projector and a silver screen World’s Fastest Polarization Switch DepthQ ® switches states nearly instantaneously in both directions.
Competing technologies are significantly slower.
OLD TECH (Pi-cell) DEPTHQ ®
10x Faster than old Pi-cell Liquid Crystal technology Slow, Asymmetrical, Unpowered state change Fast, Symmetrical, Powered state change
Image Excellence DepthQ ® is clear and flat with high extinction - allowing
sharply focused, bright, low-ghost 3D images.
Open transmittance: 32% >15% at projection (measured through common low-cost 3D glasses) Future-Proof With the world’s fastest switching speed, DepthQ ® is
already capable of 400FPS.
Peter Jackson’s The Hobbit and James Cameron’s Avatar prequels will require high-end projectors to run at
192FPS and 240FPS
BIG Projections DepthQ ® can ‘take the heat’
supports 3D screens up to ~18.3m (60ft).
Advanced heat protection allows unlimited lamp power and large 3D screens, e.g. 18.3m (60ft) screens using a 6KW lamp,
and even larger with higher wattage lamps.
Durable with Low-Maintenance DepthQ ® provides both active AND passive heat-protection for
longevity.
Electronic switching has no moving parts for
low cost / maintenance.
DepthQ ® ADDS high-tech heat protection. Others do not.

- Advantages Over Old Technology -
Competing methods for viewing digitally projected stereoscopic images are leveraging patents filed in the 1980’s.
COMPETING TECHNOLOGIES: Pi-cell Liquid Crystal

Pre-1985
The DepthQ ® Polarization Modulator is a
newly- patented process
for polarization switching, not an old technology.
Patent issued September 2011
DepthQ ® switches states nearly instantaneously in both directions. Competing technologies are
significantly slower
.
Key design features:
• Ultra-fast switching between two polarization states • Superior response time: 50 microseconds (µs) in both directions • This results in a very small potential ‘Dark Time’ - only 0.72% @ 144Hz (Dark Time = time to change from Left state to Right state, or vice versa)
OLD TECH (Pi-cell Liquid Crystal) DEPTHQ ® Conventional polarization modulator illustrating slow transition in one direction (~500 µsec) DepthQ
©
Polarization Modulator Illustrating near-instantaneous switching in both directions (~50 µsec)
DepthQ ® is clear and flat with high extinction - allowing sharply focused, bright, low-ghost 3D images.
Key design features:
• Completely symmetric operation between left and right eyes, with high extinction at all wavelengths for dark states • Contrast ratio: >100:1 • Open transmittance: 32%, >15% at projection
measured through common 3D glasses
• Flatness/distortion quality-controlled using laser scanning
With today’s projector technology, slow Pi-cell switching can cause
excess ghosting
.
Their problem:
• Old Pi-cell technology requires ~
500µs
to fully change states • In an effort to keep 3D as
bright
with Pi-cells is often set as
short
as possible, digital cinema projector ‘Dark Time’ as currently possible: about
350µs
• This means projectors can switch eyes before Pi-cells finish switching state,
allowing excess ghosting
Pi-Cell switch time exceeds typical Pi-cell Dark Time You choose between
extra ghost
or
dimmer image
DepthQ ® switches well within typical Dark Time –
No chance of excess ghosting.
In the future, if projector Dark Times are reduced below 350 µ s, DepthQ ® will allow even
brighter images.
How?
• Dark Times are used to hide state changes from Left Eye to Right Eye and back • Overall projector brightness is
diminished
by Dark Times • The smaller the Dark Time, the brighter the final image At 50µs, DepthQ ® potential Dark Time is almost
inconsequential:
Less than 1% of a frame (.72%) at today’s 144FPS speeds.
In the near future, projector manufacturers will begin to adopt new High Frame Rates (HFR).
DepthQ ® is more than ready.
What’s driving faster 3D projectors?
• Peter Jackson’s The Hobbit trilogy was shot at 48 frames per second (FPS) • James Cameron’s Avatar prequels will likely be shot at 60FPS • This will require high-end projectors to jump to
192FPS
for 3D,
and potentially 240FPS
With the world’s fastest switching speed, DepthQ ® is already capable of
400FPS
.
DepthQ ® ’s 50 µ s fast switching is even more important in conjunction with High Frame Rate movies/projectors.
Why?
• At 192FPS DepthQ ® will only require
.96%
of a frame for Dark Time • At 240FPS DepthQ ® will only require
1.2%
of a frame for Dark Time Pi-cells will consume
10-12%
of your projectors’ light in Dark Time
.
Competitive products use plastic linear polarization elements. DepthQ ® uses
nano-scale metal on glass
to ensure longevity.
Why?
• Powerful lamps in digital cinema projectors create infra-red (thermal) energy which projector manufacturers filter in varying amounts. • Thermal heating can melt, warp and degrade the plastic linear element of any circular polarization modulator over time. DepthQ ® employs this extra layer of high-tech protection to
reflect
harmful thermal energy while pre-polarizing incoming light.

Included with DepthQ ® is a fast show-controllable actuator for
s
witching between 2D and 3D.
