Abstract
The Need:
Virtually all microdisplay-based projection systems built to date have used an
HID lamp such as the UHP as a light source. While lasers have been proposed as
replacements for the lamp as far back as 6, cost and performance of these
systems has rarely been satisfactory. Today only extreme high-end projectors
use laser illumination. There is a need for an evaluation of lasers in terms
of technology, architecture, price and performance, and compare these
parameters to the existing and forecast markets for projection systems.
Report Objective:
The objective of this report is to supply technologists, managers, product
planners, engineers and researchers with the information needed to evaluate
laser technology in proposed projection displays. The required information
needed to make these decisions include performance data, colorimetry, laser
power requirements, cost information and availability, forecasted from 5-0.
Since the projection market includes segments that range from very low end to
very high end, this report evaluates lasers from a few milliwatts to 5 watts
of optical output per color, as well as a number of laser-based projection
system architectures.
