Product Description
ColorSwitch is a transparent device, containing liquid crystal switches and patented technology for chromatically manipulating polarization. ColorSwitch features independent electronic control of the RGB transmission levels providing additive and subtractive primary outputs as well as Black and White. Analog control permits active color balance and switching between display standards. Sequences can easily be changed on-the-fly, with no fundamental requirement for a repetitive periodic output. The architecture is robust, using the LC switches to determine luminance, without influencing chrominance during switching. Our additive drive-to-black design provides maxi-mum brightness without color mixing during transitions.
Benefits
ColorSwitch is a solid-state alternative to conventional mechanical color wheels with the following advantages:
- Noise and vibration free
- Easily synchronized to panel
- Programmable color sequencing
- No moving parts for high MTBF
- Absorption free for high transmission
- Low weight and compact size

Applications
ColorLink devices provide a unique solution for colorizing a wide variety of display and imaging devices:
- DTV including HDTV
- Rear projection computer monitors
- Multimedia front projection
- HUD (Heads - up display)
- HMD (Helmet mounted display)
