The colour images travel as three separate beams of light and hit the wall. Here the colours fall on each other to produce the true colour . LCD Projectors

5. DLP (digital light processing) uses thousands of microscopically small mirrors, which not only move pixels closer together for higher contrast and greater clarity, but also provide greater brightness than LCD projectors. DLP’s high resolution makes it ideal for projecting images or videos in HD (high definition). Like LCD projectors, many DLP projectors also feature audio.
