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.

Technical Brief—Multimedia projectors Page 2

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.
