DepthQ® Polarization Modulator - 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 1987 Spinning Polarizer 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® DepthQ© Polarization Modulator Illustrating near-instantaneous switching in both directions (~50 µsec) Conventional polarization modulator illustrating slow transition in one direction • (~500 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 as possible, digital cinema projector ‘Dark Time’ with Pi-cells is often set as short 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 350µs, 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 50µs 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. Nano-scale pre-polarizer wire pattern
Included with DepthQ® is a fast show-controllable actuator for switching between 2D and 3D. 3D mode 2D mode Actuator in motion - ~4 seconds in either direction
Finally, we are so confident in our quality and longevity, we offer a Digital Cinema Five Year Optical, Three Year Electronics/Mechanical Warranty.
