An Introduction to DLP & LCD Projectors
By ama | April 11, 2009
There are many specs and parameters to take into consideration when buying for example a brand new or used Sharp Projector. We will learn about two important yet easy parameters in this post; they are projector panel type (LCD or DLP) and brightness. We hope this basic information will help you to make a better informed decision about your future projector.
Projector Brightness
Often the most noticeable projector parameter is brightness. This parameter interacts the most with your projection location, thus the location should be a major consideration in your projector choice and determining the amount of lumens (units of brightness) needed. In addition to light and lumens, adjustability plays an important role for portable projectors. If you are willing to spend more money, you can usually get more lumens or brightness in a projector. As technology advances, the standards will move upwards, in any case though for now, here are some rough guidelines for luminosity amount and projector use; please be aware that these are just loose recommendations and are not written in stone.
• 3000 ANSI lumens or more. These are really bright projectors suitable for use in very large venues or even outdoors. High lumen projectors also excell at greater distances and projecting larger screen sizes.
• 1800 - 3000 ANSI lumens. Perfect for classroom presentations and big lectures, high end home theater and TV viewing, DVDs and more.
• 1000 to 1800 ANSI Lumens are generally fine for basic business presentations and meetings in darkened rooms, simple graphics, general entertainment and games.
LCD or DLP
LCD and DLP are currently the dominant projector panel technologies. LCD happens to be the most popular technology these days. DLP technology is licensed from Texas Instruments, more proprietary, and slightly more expensive than LCD panel technology like that used in the NEC LCD Projector. Projectors with LCD panels are also noted for their vivid and deep colors as well as high lumen outputs.
DLP technology projectors seem to be in a similar or slightly higher price range, but they are typically able to produce images with higher contrast ratios and deeper, darker black levels than LCD projectors. DLP is also very popular in home theater enthusiast circles for it's ability (high end DLP projectors) to create a strikingly film like experience. DLP lamps are believed by some to last longer than LCD lamps. Get some real world practice by looking at the specs of the DLP Home Theater Projector and find out for yourself what they are capable of.
