What does DLP mean and does it have a tube?
DLP means Digital Light Projection. It’s a Texas Instruments technology which uses a spinning color wheel and millions of tiny mirrors to reproduce an image. The sets are not flat, but most weigh less than LCD or plasmas (no glass layers). They generally are found in the higher sizes, available up to 70” in the consumer space, and for the size are less expensive than flat panel technology.
They do have some drawbacks, however. Some people can experience a rainbow effect when looking at a fast moving image. Newer models fix this problem by using three separate color wheels I believe instead of one. Blacks are not as good as CRTs or plasmas, but better than LCDs. Also, if you play video games, some models have issues with the delay in presenting the image if you’re not using the latest a greatest HD connection, though honestly I haven’t noticed this before.
DLP = digital light processing no tube, just one user relceable lamp and about a million mirrors
