About LCDToday all projectors using LCD technology use 3 LCD micro-display chips with one for each of the three primary colors (i.e., red, blue and green). These are commonly referred to as 3LCD projectors. The LCD micro-displays are transmissive in that light must pass through from the back of the display panel. This is similar to LCD flat panel TVs which use either a LED or fluorescent backlight located behind their transmissive display panel. In the past LCD based projectors suffered from higher black levels and lower contrast ratios as compared to the better DLP projectors. However, significant improvements in LCD projection technology in recent years has resulted in overall performance levels from today’s better 3LCD projectors being highly competitive with projectors within their same price range that employ the other competing projection technologies (either DLP or LCoS). The home theater class 3LCD projectors generally offer better placement flexibility, by offering wide range zoom lenses and lens shift adjustments, as compared similar priced DLP models. 3LCD projectors frequently offer a winning combination of performance and features that make them popular for the mid-price range models of business, education or home theater projectors. 720p 3LCDBudget 3LCD home theater-class projectors with 720p native resolution represented by models such as the Epson Home Cinema 710HD (pictured) with a list price of $649.
