OLED with minimal plasmonic losses

Forrest, Stephen R.; Kim, Jongchan

Title: OLED with minimal plasmonic losses

Abstract

A top-emitting organic light emitting device (OLED) that comprises: a substrate having an inward side and an outward side; an OLED body that includes a transparent bottom electrode proximate to the inward side of the substrate, an organic emitting layer, and a transparent top electrode in that order; a non-metallic, diffuse reflective layer with a roughened top surface proximate to and facing the bottom transparent electrode; and a high refractive index waveguide layer. The diffuse reflective layer is positioned between the inward side of the substrate and the OLED body, and the waveguide layer is positioned between the diffuse layer and the bottom transparent electrode.

Passive magnetic bearing element with minimal power losses

Patent Post, Richard F [Walnut Creek, CA]

Systems employing passive magnetic bearing elements having minimal power losses are provided. Improved stabilizing elements are shown, employing periodic magnet arrays and inductively loaded circuits, but with improved characteristics compared to the elements disclosed in U.S. Patent No. 5,495,221 entitled "Dynamically Stable Magnetic Suspension/Bearing System." The improvements relate to increasing the magnitude of the force derivative, while at the same time reducing the power dissipated during the normal operation of the bearing system, to provide a passive bearing system that has virtually no losses under equilibrium conditions, that is, when the supported system is not subject to any accelerations exceptmore » those of gravity.« less

Host cells and methods for producing 3-methyl-2-buten-1-ol, 3-methyl-3-buten-1-ol, and 3-methyl-butan-1-ol

Patent Chou, Howard H [Berkeley, CA]; Keasling, Jay D [Berkeley, CA]

The invention provides for a method for producing a 5-carbon alcohol in a genetically modified host cell. In one embodiment, the method comprises culturing a genetically modified host cell which expresses a first enzyme capable of catalyzing the dephosphorylation of an isopentenyl pyrophosphate (IPP) or dimethylallyl diphosphate (DMAPP), such as a Bacillus subtilis phosphatase (YhfR), under a suitable condition so that 5-carbon alcohol is 3-methyl-2-buten-1-ol and/or 3-methyl-3-buten-1-ol is produced. Optionally, the host cell may further comprise a second enzyme capable of reducing a 3-methyl-2-buten-1-ol to 3-methyl-butan-1-ol, such as a reductase.

Patent Leung, Wai Y.; Park, Joong-Mok; Gan, Zhengqing; ...

Provided are microlens arrays for use on the substrate of OLEDs to extract more light that is trapped in waveguided modes inside the devices and methods of manufacturing same. Light extraction with microlens arrays is not limited to the light emitting area, but is also efficient in extracting light from the whole microlens patterned area where waveguiding occurs. Large microlens array, compared to the size of the light emitting area, extract more light and result in over 100% enhancement. Such a microlens array is not limited to (O)LEDs of specific emission, configuration, pixel size, or pixel shape. It is suitablemore »« less
