The new DepthQ Polarization Modulator electronically switches the polarization orientation of light passing through it. In combination with a polarization-preserving screen and a single-lens stereoscopic 3D projector like the DepthQ HD 3D Projector, this enables high-brightness, low-ghost viewing using lightweight & comfortable passive 3D eyewear.

The DepthQ Polarization Modulator utilizes a unique 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 (<0.5ms at room temperature) between polarization states at frequencies from 120Hz to 400Hz.
