General Information
Designed for the LCOS based consumer RPTV market, CQ3® balances industry demands on performance, reliability, and form factor with cost. Enabling high performance ultra slim LCOS TV cabinets, CQ3 allows significant cost reductions through reduced component count and back focal length demands. The world’s smallest LCOS color management module comes backed with a mature technology and manufacturing process. |

Product Description
CQ3 is an improved ColorQuad®, fine tuned to the demands of the consumer rear projection television (RPTV) market. By dropping an output absorptive polarizer, replacing one PBS with a dichroic filter and reducing the number of ColorSelect® filters from five to three, CQ3 delivers on performance and reliability at significantly reduced cost. In addition, CQ3 is designed to minimize mechanical interference with projection lens and enhance ease of integration with illumination system providing further cost reductions to OEMs. By relying on an improved class of ColorLink® filters that selectively rotate the polarization of one color relative to its complementary, high contrast and excellent color gamut of ColorQuad are maintained. Light throughput is now improved 30% and cost reduced by a factor of 2.
Benefits
CQ3 offers unique advantages including:
- Low cost
- Short back focal length and compact size
- High brightness and contrast
- Color fidelity without sacrificing panel bit depth
- Reduced component count
|
Applications
CQ3 is a color management system designed to enable high-resolution LCOS based consumer RPTV.
Modifications of CQ3 are available for several applications including:
- Home theatre front projectors
- Automotive head-up displays
- Avionics cockpit projection displays

Configurations
CQ3 can be modified to customer specified color points with custom filter sets.
The “180 degree” configuration (shown here), where input light is parallel to the output, can be easily modified into a “90 degree” configuration where input light is perpendicular to the output.
Spectral Characteristics
A unique feature of CQ3 is the balanced white state. In addition to notching-out the yellow light from typical UHP lamps, CQ3 will generate a perfectly balanced white point of approximately 10,000K when the three micro displays are run in their ‘full-ON’ state. This allows the full dynamic range of the micro displays to be used for gray scale. Measured data for the CQ3 using UHP lamp at f/2.8 is provided. |
