DepthQ® Modulators are the world's fastest polarization switches for 3D digital projection

Newly patented technology* makes DepthQ® the world’s fastest polarization switch for advanced 3D visualization. With a powered, symmetrical 50 µsec switching time between the eyes, DepthQ® easily ensures bright, low-crosstalk operation - even at the upcoming 3D HFR
(high frame rate) targets of 192 FPS, 240 FPS...and beyond.

The new DepthQ® Polarization Modulators electronically switch the polarization orientation of light passing through them. In combination with a polarization-preserving screen and a single-lens stereoscopic 3D projector (as bright as you need - no lamp/Lumens limit with the large modulator), this enables high-brightness, low-ghost viewing using lightweight & comfortable passive 3D eyewear.

TECHNICAL DESCRIPTION

DepthQ® Polarization Modulator apertures
*LC-Tec Displays AB U.S. Patent No. 8023052 B1

An unprecedented 50 microsecond symmetrical switching time makes DepthQ® the world's fastest polarization switch for 3D digital projection.

By actively alternating between 'left-handed' and 'right-handed' circular polarization orientations in sync with progressive L/R stereoscopic data, standard circular polarized eyewear can passively block or transmit light to the viewer's eyes for the appropriate image. This efficient, high-speed switching between the eyes ensures bright, low-crosstalk, flicker-free 3D whatever your flash rate - be it 100Hz, 120Hz, 144Hz or as high as 400Hz.

With high frame rate (HFR) projectors capable of 192 and 240Hz already being marketed, this ensures a future-proof investment.

The system includes both the liquid-crystal modulator as well as its control unit. A standard sync output from your graphics card or projector's GPIO port is supplied to the control unit, which then conditions the signal to match the modulator’s required input.

The modulators are available in two sizes: Small, with a 16:10 ratio aperture of 9.84cm wide (3.875in) for projectors up to 4K Lumens, and Large, with a 16:9 aperture of 17.15cm wide (6.75in) for projectors up to 34K Lumens.

The optical window of the large modulator is also heat-protective, employing a nano-scale metal-on-glass pre-polarizer to reflect thermal energy and ensure longevity.

Paired with projectors up to 34K ANSI Lumens, DepthQ® polarizers provide a compelling 3D experience for polarization-preserving screens up to 18.3m (60ft).
