The engine is based upon a ColorQuad acrchitecture with three
0.7-inch panels offering 1280 x 720 pixels of resolution. Currently,
the panels are supplied by Three-Five Systems, but CPT says the
panel supplier for the final product is still not determined.
The engine uses a 100W lamp and it outputs 400 ANSI lumens with
80% uniformity and contrast of 450:1.
This engine was packaged into a rear-projection demonstrator
that was 19 inches deep. A 42-inch Toppan screen with a 3.8X gain
was used. This produced 890 nits of brightness.
CPT is not yet ready to commercialize the set, even though it
is satisfied with performance levels. "The cost is too high,"
notes CPT senior manager of Product Planning & Marketing,
Shih-Chieh (Jessie) Chou. "To be commercially viable, CPT
believes the engine cost needs to be near $1,200, going to $1,000
very quickly." It is also a bit worried about ColorQuad availability.
To reach this goal, CPT is evaluating internal engine manufacture,
while also surveying external LCOS engine makers. "If possible,
CPT will commercialize the LCOS TV as soon as possible."
Chou also notes that CPT is working on a low-cost HTPS-based
rear-projection TV set now using 0.7-inch SVGA panels. That should
be ready by October.
