LCD projectors work better for static Microsoft PowerPoint presentations or detailed financial spreadsheets. DLP works better for full motion video. LCD stands for Liquid Crystal Display and DLP stands for Digital Light Processing. LCD is an analog-based display technology employing three fixed panels of pixels (one panel each for the RED, GREEN, & BLUE components of an NTSC video image). LCD also delivers a somewhat sharper image than DLP at any given resolution. LCD projectors usually produce significantly higher ANSI lumen outputs than do DLP projectors with the same wattage lamp.DLP projectors have a much higher pixel "fill factor"? than LCD. DLP-based projectors generally produce a much smoother looking image compared to LCD-based projectors of similar resolution. DLP-based projectors have a high contrast ratio and efficient use of light. Contrast ratio compares the ratio between the brightest white and the darkest black that a projector can produce. Generally, a better contrast ratio leads to better black levels and, therefore, a more realistic presentation of darker scenes in movies and TV programs. DLP projectors tend to be more compact because they have fewer components. All of the current 3-pound portable projectors on the market are DLP projectors. Most LCD projectors are five pounds and up. The higher lumen models are significantly heavier and larger. High lumen projectors are not considered portable. You need to match the brightness of the projector to your audience and room size. Large rooms and audiences require high bulb strength brightness. (Projector bulb strength brightness is measured in ANSI lumens or lumens). All projector rentals range from about 1000 up to 6000+ lumens in brightness. The higher the lumen the brighter the projector. Up to 1000 lumens -good for low ambient light, presentations. 2000 lumens -These are the most popular units being sold and rented today. Very practical and will work with some ambient light. 3000 lumens -Much Larger unit than the1000 to 2000 lumen units. Good for audiences of less than a hundred with ambient light. 5000 lumens - For audiences of 100 or more under brighter lights 6000+ lumens - For large events like conventions, conferences and tradeshows where thousands of people need to view a presentation at the same time. Another consideration is portability of the projector. Lower lumen units are the most portable. As a general rule, as you increase bulb strength brightness, you reduce portability. High lumen projectors are larger and weigh more than low lumen projectors.
