Rear Projection: DLP
DLP (digital light processing) projectors work by manipulating thousands of tiny mirrors on a semiconductor chip. Color is generated by shining a light through a rotating color wheel that has red, green, and blue on it. The now colored beam hits the semiconductor chip to create the image used for projection.Pros:
- They have an excellent picture.
- They are capable of displaying HDTV at full resolution.
- They require no maintenance.
Cons:
- They are expensive.
- They have a limited viewing angle.
- Some people notice a "rainbow effect" in DLP systems that use a segmented color wheel.
