  DLP stands for Digital Light PROCESSOR (I think)  Actually many thousands
of tiny mirrors produced on a chip the way integrated circuits are made.
The big benefit of LCD (Liquid Crystal Display) is the DLP projectors have
about a 100x increase in contrast ratio... meaning  much blacker blacks.

  The DLP projectors are more expensive than the LCD, but both kinds have
models under $1,000 nowdays with plenty of lumnens of brightness.
