The present invention is generally directed to semiconducting compositions containing a guest material and a light emitting organic host material. These compositions are useful for color tuning and improving efficiency in an electroluminescent device. It further relates to a process for preparing the compositions and the layers and devices that are made with the compositions.

In one embodiment, the organic electronic device includes a substrate and a first conductive member overlying the substrate and lying at least partly within the array. The first conductive member is at least part of a first power transmission line. The organic electronic device further includes a second conductive member overlying the substrate and lying at least partly within the array. The second conductive member is at least part of a first electrode and is electrically connected to the first conductive member. In another embodiment, an organic active layer has at least a portion lying between the first and second conductive members. In yet another embodiment, a process for using an organic electronic device including an array of radiation-emitting components allows radiation to be emitted from the array at an intensity of at least 1100 cd/m2.

摘要:
The present invention relates generally to fabricating two-terminal electric microswitches comprising thin semiconductor films and using these microswitches to construct column-row (x-y) addressable microswitch matrices. These microswitches are two terminal devices through which electric current and electric potential (or their derivatives or integrals) can be switched on and off by the magnitude or the polarity of the external bias. The microswitches are made from semiconducting thin films in a electrode/semiconductor/electrode, thin film configuration. Column-row addressable electric microswitch matrices can be made in large areas, with high pixel density. Such matrices can be integrated with a sensor layer with electronic properties which vary in response to external physical conditions (such as photon radiation, temperature, pressure, magnetic field and so on), thereby forming a variety of detector matrices.

The automated social networking graph mining and visualization technique described herein mines social connections and allows creation of a social networking graph from general (not necessarily social-application specific) Web pages. The technique uses the distances between a person's/entity's name and related people's/entities names on one or more Web pages to determine connections between people/entities and the strengths of the connections. In one embodiment, the technique lays out these connections, and then clusters them, in a 2-D layout of a social networking graph that represents the Web connection strengths among the related people's or entities' names, by using a force-directed model.
摘要:
A liquid crystal lens cell set includes a plurality of liquid crystal lenses overlapping to each other. Each of the liquid crystal lenses is supported between a pair of flat layers. One of the layers supports a planar electrode made of ITO. The other electrode, also formed of ITO, is supported in the center of the opposing substrate and projects toward the center of the liquid crystal layer. A power supply creates a potential difference between the electrodes and imposes a non-uniform electric field on the liquid crystal modules which aligns them in which a way as to act as a lens. By varying voltage between the electrodes the focal length of the lens may be controlled. A central electrode may be in the form of a beam or of a pointed tip. An electrode having a central hole may be associated with the central electrode or the planar electrode.

Firmware updates at an information handling system flash memory device, such as provisioning information stored on a USB device, are securely performed by using a buffer memory and a secured code. An application running on a CPU generates a firmware update and a security code, such as a ciphered hash code based on the firmware update, stores the firmware update and security code in a buffer, and informs a management processor of the update. The management processor analyzes the firmware update to authorize copying of the update from the buffer to the flash memory device. For instance, the management processor creates the security code from the firmware update and compares the created code with the security code stored in the buffer to validate the firmware update.
摘要:
Organic photodetectors with switchable photosensitivity are achieved using organic photoactive layers in electrode/organic/electrode structures. The photosensitivity can be switched on and off by the biasing voltage across the detectors, the switching voltage imparting photosensitivity above 1 mA/W at a preselected operating bias and near zero photosensitivity at a cut-off bias substantially equivalent in magnitude to the built-in potential of the photodetector. The photocurrent can be probled with a read-out circuit in the loop. These photodetectors can be arranged in linear arrays or in two-dimensional matrices that function as high performance, linear or two-dimensional image sensors.
摘要:
A method of emulsion polymerization of aniline or substituted anilines for making substituted or unsubstituted homopolymers and co-polymers of aniline. The method includes formation of an emulsion of aniline monomers, polar solvent, non-polar or weakly polar solvent and functionalized protonic acid, which is selected for its ability to perform two functions: acting as a surfactant and acting as a protonating agent (dopant) in producing an electrically conducting polymer. Then, an oxidant is added to polymerize the ingredients of the emulsion. This method provides polyaniline particles of highly crystalline and oriented morphologies of controlled aspect ratios.
摘要:
The addition of a highly polarizable additive such as an organic anionic surfactant to an electrically active polymer improves the electrical properties of the polymer. When such an additive is added to an electroluminescent organic polymer this mixture can be used in diodes having an anode contacting a layer of this mixture as the active light-emitting layer and an air-stable metal cathode having a work function larger than 4 eV. The external efficiency and brightness versus voltage are significantly improved compared to results obtained with the same electroluminescent polymer used alone with high work function (>4.0 eV) metal cathodes. Specifically, device performance with indium/tin-oxide (ITO) as the anode, poly(2-methoxy-5-(2'-ethyl-hexyloxy)-1,4-phenylene vinylene), MEH-PPV, as the electroluminescent polymer, lithium nonylphenoxy ether sulfate as the surfactant additive and aluminum as the cathode is comparable to or better than that obtained with high performance devices using calcium as the cathode.
