DLP
DLP stands for digital light processing and is a technology common to high definition televisions. DLP televisions are thought to produce deeper blacks but some people have pointed out a phenomenon known as the "rainbow effect" which appears as colored streaks on the screen when the picture is rapidly changing such as during a sporting event. DLP competes with LCD and plasma technologies.
