3D? 240 fps? 30,000 lumens? Ask DepthQ!
Newly patented technology makes DepthQ the world’s fastest polarization switch for 3D digital cinema. Pu the dice in front of a 3D cinema projector lens, and, with a 50 microsecond switching time between the eyes, DepthQ easily ensures bright, low- crosstalk operation - even at the upcoming 3D high frame rates of 192 Frames per second (FPS), 240 FPS...and beyond.
When combined with a silver screen, the DepthQ Polarization Modulator allows your digital cinema projector to display stunning stereoscopic 3D films, viewable using inexpensive passive glasses. Paired with projectors up to 30K Lumens, DepthQ provides a spectacular 3D experience for screens up to 17.7m (58ft).
As its names implies, the modulator modulates the polarity of light passing through it, in perfect synch with the double or triple-flash of left and right eye images from digital cinema projectors. To date, the DepthQ Polarization Modulator has been successfully reviewed by executives from six major Hollywood studios and is listed on the Walt Disney Studios Motion Pictures Approved Equipment List.
The DepthQ Polarization Modulator utilizes a unique control methodology and combination of separate liquid crystal elements bonded together, enabling both high polarization efficiency over visible wavelengths from 400 to 750 nm (predominantly achromatic spectral response) as well as fast transition switching speeds between polarization states (50 microseconds) at frequencies from 96 to 400 Hz. This 50µs switching time actually occurs faster than the smallest dark interval setting currently available in digital cinema projectors...so when they 'catch up', even brighter 3D images will result!
By actively alternating between two orthogonal polarization orientations in sync with the progressive left/right double or triple-flash of stereoscopic cinema projections, matching polarized eyewear can passively block or transmit light to the viewer's eyes at the appropriate moment. Efficient, powered, symmetrical high-speed switching between the eyes ensures bright, low-crosstalk, flicker-free operation.
The system includes both the liquid-crystal modulator as well as its control unit, plus hardware which mounts the unit to the front of your projector, and an actuator to move the modulator in and out of the projection path (for switching between 2D and 3D). Sync output from your projector's GPIO port is supplied to the control unit, which then conditions the signal to match the modulator’s required input.
Co-development
The DepthQ Polarization Modulator is co-developed by Lightspeed Design, Inc. and LC-Tec Displays, AB. The two companies have over 19 years of experience in their respective fields of stereoscopic design and liquid crystal manufacturing and development.
