This technical brief provides detailed information on the following topics, related to all EPSON multimedia
projectors:
Image quality
Versatility
Image Quality—Superior brightness
All EPSON multimedia projectors include EPSON's integrated LCD prism technology. This technology is centered
on EPSON's patented optical engine.
EPSON's engine includes 3-panel Poly-Silicon TFT LCD's:
Size ranging from 1.32 inches to 0.9 inches
Resolutions from SVGA to XGA to SXGA.
Improvements in the precision of this LCD structure has allowed
EPSON projectors to reach a superior level of brightness with a
combination of these five technologies, included in most EPSON
projectors:

1. UHE lamp:

The long-life Ultra High Efficiency (UHE) lamp uses a shorter arc
length. This shorter length is the primary factor in achieving higher
efficiency.

2. Polarization conversion:

EPSON's technology has improved the amount of parallel light
that moves through the LCD panels. More light passes through
each LCD because it is polarized without a filter.
