What is the DarkChip 3?
DarkChip 3 is a recent improvement on the
DarkChip line of DLP chips from Texas Instruments. It features a black
coating on the DLP hinge structure and other internal parts.
Essentially, anything that’s not a mirror is coated with a light
absorbing material that
reduces light spill. This significantly improves the black level
performance of DLP projectors, like the Optoma H78DC3, which use these
chips. A lower black level means a higher contrast ratio, and improved
picture quality.
