Everything You Need to Know About TV Technologies

DLP Projector

It functions just as the rear-projector version. The lamp shines light through a spinning colored wheel and then over the DMD micromirror-covered chip to be reflected to the lens, where the resulting image is focused and amplified to the screen. Since there are models with Full HD 1080p resolution, the DLP projector is favored by home theater enthusiasts. The same technology is also used in DLP-based movie theaters with special 3-chip projectors capable of displaying 35 trillion colors.

Model example: Optoma HD80
