Light-emitting diode design allows precise control of colors and intensity
Polychromatic light-emitting diodes that incorporate 3D faceted microstructures provide good control of color, including pure white emission, without depending on phosphors.
Integrating microlens arrays onto microcavity top-emitting organic light-emitting devices produces displays with an unparalleled combination of useful properties, including enhanced luminance and wide viewing angles.
White organic light-emitting diodes offer a power efficiency, lifetime, and brightness that together constitute a significant advance toward viable devices for lighting.
A new device architecture incorporating an exciton blocking layer is efficient enough at high luminance to be used in large displays and solid state lighting.
Improvements in LED brightness and efficiency have brought many applications of solid-state lighting out of the lab and into the real world. What will it take to get them into homes and offices?
