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 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.
