Abstract

Light sources with digitally addressable elements have many potential uses in the lighting and display space. At the lighting end of the application range, recent developments have resulted in phosphor-converted segmented LEDs and mini-LEDs with single element dimensions of the order of 100 µm. When combined with suitable directional optics and controls this device architecture can generate dynamic light distributions for a wide variety of scenarios. Initially developed for Adaptive Driving Beam (ADB) technology for vehicle headlights, the basic concepts translate to many general lighting applications where they provide a completely new approach to reduced power consumption, improved illuminance uniformity and digitized design and commissioning. At the display end of the range, micro-LED technology with typical pixel sizes of the order of 1 µm to 10 µm promises to reduce power consumption of both direct-view and projection displays, enabling practical wearable AR/VR devices. In this paper, we will present our integral approach to micro- and mini-LED device technology and backplane integration across this application range and describe a prototype light engine designed to evaluate the benefits of this technology in lighting applications.
