58.3: A New LED Light Source For Projection Applications

Abstract

A new kind of LED light source with high brightness levels suitable for use in ultra-compact projection devices was developed. We present a unique chip technology and the correctly matched package design that enable a superior performance and discuss all of the aspects of using this LED light source in a projection application.

61.3: LED Light Source for RPTV Applications

“…The light source presented in this article is based on a new generation of large high-current dies, "Thin Film" AlGaInP for red and "ThinGaN ® " for blue and green light, which are already introduced with the OSTAR projection package, which aims at pocketprojector applications [4]. These thinfilm dies implement several new design ideas that lead to high efficiency and output luminous flux with outstanding luminance (i.e.…”

“…High-brightness LEDs are an alternative light source in volume constraint projection display applications [1][2][3][4]. These devices are durable and the dimensions of the light source and the low operating voltage facilitate a compact system design.…”

61.5: LED-Based Light-Recycling Light Sources for Projection Displays

“…LED-based projection systems have recently been developed [1][2][3][4] that have several significant advantages compared to systems based on arc lamps. LEDs have longer lifetimes than arc lamps and can be pulsed for color sequential imaging.…”
