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:

Three-panel design:
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.
Parallel light beam Non-parallel light beam
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.
EPSON-made Poly-Silicon LCD's are
manufactured to the highest standards.
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:
Size ranging from 1.32 inches to 0.9 inches
Resolutions from SVGA to XGA to SXGA.

Image quality—Image clarity
EPSON projectors producte astonishingly clear, sharp images with a combination of these three technologies:
3. High aperture LCD panels:
The UHA (Ultra High Aperture) has increased the aperture ratio which allows more light through the lens.
EPSON produces the highest aperture LCD's, which are more transmissive.
4. Micro Lens Array:
MLA is a layer of the LCD composed of quartz crystal lenses. Each pixel has a dedicated lens that focuses and
maximizes the throughput of light from the lamp. MLA allows more light to pass through each pixel, more
than twice the light of LCD's of two years ago. (Not included on all EPSON projectors.)
5. "Metal Sandwich" technology:
A light shield of metal between the pixels blocks the light leakage. Cross-talk between pixels is reduced,
resulting in clearer, crisper images. (Not included on all EPSON projectors.)
1. High illumination ratios:
The illumination ratio measures the relationship of the darkest spot (the corner) to the brightest spot on the
screen (the center). The higher the ratio, the more uniform the brightness.
2. High contrast ratios:
Contrast ratio measures the difference between the light and dark areas of the image. The higher the ratio the
sharper, more colorful, and more lifelike the images appear.
EPSON projectors produce
smooth, evenly lit images with
sharp contrast.
Competitive units can produce
"hot" centers with dark corners
and fuzzy contrast.

Image quality—Keystone correction
Many EPSON projectors provide keystone correction, which allows you to correct up to a ±20
0
tilt while
maintaining the correct aspect ratio.
3. Panel on Prism (POP):
This technology allows little or no shift between the LCD panels and the prism, which keeps the pixel alignment
precise and the image sharp and clear.

Without keystone correction
With keystone correction
Set up your projector so the lens is
aligned with the bottom of the screen.
If you can't set the projector up aligned
with the screen, then the keystone
correction will correct the misalignment.
