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.

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 vs. Competitive units can produce smooth, evenly lit images with "hot" centers with dark corners sharp contrast. and fuzzy contrast.
