Journal ArticleDOI
Ink-jet printing of doped polymers for organic light emitting devices
TL;DR: Ink-jet printing was used to directly deposit patterned luminescent doped polyvinyl carbazol (PVK) films as mentioned in this paper, and light emitting diodes with low turn-on voltages were also fabricated in PVK doped with coumarin 6 (C6).
Journal ArticleDOI
Improvement of output coupling efficiency of organic light-emitting diodes by backside substrate modification
TL;DR: In this article, the authors applied spherically shaped patterns to the back of an organic light-emitting diode to capture light previously lost to waveguiding in the substrate and, with proper choice of substrate, to recover the lost light in the organic/anode layers.
Journal ArticleDOI
External coupling efficiency in planar organic light-emitting devices
M. H. Lu,James C. Sturm +1 more
TL;DR: In this paper, the external coupling efficiency in planar organic light-emitting devices is modeled based on a quantum mechanical microvavity theory and measured by examining both the far-field emission pattern and the edge emission of light trapped in the glass substrate.
Proceedings ArticleDOI
Improved external coupling efficiency in organic light-emitting devices on high-index substrates
TL;DR: In this article, high-index-of-refraction substrates were used to increase the external coupling efficiency of organic light-emitting devices (OLEDs) by using a quantum mechanical microcavity model.
Proceedings ArticleDOI
Printing approaches for large-area color organic LED displays
TL;DR: In this paper, the fundamental properties underlying the transfer of organic fluorescent dyes to local areas in polymer thin films by both liquid phase (ink-jet printing) and evaporation/diffusion transport methods are examined, with the goal of achieving full color displays based on organic light emitting diodes made from such polymers.
