How does a cinema laser projection system work and how is it different from DLP-based technology?
A typical Laser based projectors use one or more high powered lasers to directly expose the light valve used in the projector.
Laser projectors are much brighter than DLP projectors, but suffer from a shorter lifespan due to heat buildup inside of the unit caused by continuous operation at higher power levels. Additionally they require active cooling systems to dissipate that heat build up which adds additional complexity and cost.
