We report the integration of organic light emitting devices (OLEDs) and amorphous Si (a-Si) thin-film transistors (TFTs) on both glass, and unbreakable and lightweight thin stainless steel foil substrates. The doped-polymer OLEDs were built following fabrication of driver TFTs in a stacked structure. Due to the opacity of the steel substrate, top-emitting(More)
Recently, Lemoult et al (2011Phys. Rev. Lett. 107 064301) used time reversal to focus sound above an array of soda cans into a spotmuch smaller than the acoustic wavelength in air. In this study, we show that equally sharp focusing can be achievedwithout time reversal, by arranging transducers around a nearly circular array of soda cans. The size of the(More)
Organic light emitting devices (OLEDs) which emit in the red, green and blue spectral regions are well-known. A unique property of vacuum-deposited OLEDs is that the luminescence band is red shifted from the absorption band by as much as 0.5 eV, potentially making OLEDs highly transparent throughout the visible spectrum. Such transparency offers the(More)
