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. LEDs are beginning to appear as light sources to replace lamps. There is a need for an evaluation of LEDs in terms of technology, price and performance and to compare these parameters to the existing arc lamp sources and forecast the penetration of LEDs into the projection markets.
Report Objective:
The objective of this report is to supply managers, product planners, engineers and researchers with the information needed to evaluate LED technology in proposed projection displays. The required information needed to make these decisions includes performance data, cost information and availability. Key to understanding these parameters is optical modeling of projection systems to determine how LED light can be coupled into the etendue of the projection system.
LED performance is expected to improve dramatically over the next several years. One objective of this report is to determine when it will be feasible to introduce LEDs into any particular market segment of the projection market, in competition with HID lamps and lasers.
