Rear-projection (DLP)
Digital Light Processing, or DLP, is a type of rear projection technology used in rear-projection televisions. It utilizes an optical semiconductor called a digital micromirror device that creates images using an array of microscopic mirror. Each chip utilizes about half as many mirrors as the desire resolution thanks to a form of image interlacing called wobulation.
DLP displays offer decent contrast ratios, have no chance of burn in, and are reasonably thin (although not as thin as LCD or PDP displays of comparable size). They are also lighter weight, far less expensive, and scale better than their LCD and PDP counterparts. However, DLP displays with bulbs require you to buy new bulbs for the display every 1-3 years. DLPs can also be disorienting due to a rainbow effect created by the mirrors. These two problems are reduced or absent in most newer generation models, though.
