Digital light processing
display device / From Wikipedia, the free encyclopedia
Digital light processing (DLP) projector is a kind of video projector. It uses small mirrors that reflect light. The mirrors can be moved to either reflect light or not reflect light. The mirrors move very fast. When the mirror reflects light more often, it makes a lighter color. When the mirror reflects light less often, it makes a darker color. DLP projectors can be bright and have a high resolution. This can make the picture look better. DLP projectors can be small so they can be moved more easily. Some DLP projectors are small enough to fit in a smartphone. Big DLP projectors are often used in movie theaters.
