  • Publication number: 20060159842
    Abstract: The composition of a organic (e.g. conducting polymer) solution is reformulated and the device upon which the organic solution is to be deposited is plasma treated to provide a more uniform and flat drying profile for the resulting dried film. This reformulation and treatment induces a more uniform and flatter profile when the reformulated organic solution is allowed to dry into a film on the treated device.

  • Publication number: 20060151994
    Abstract: A locking device (1) is fixed to a nut (4) and includes a coupling unit (42) insertable into a hexagonal configuration (11) of a spigot end (2) at a reduced axial distance being coupled by mutually interpenertratable gears (49, 51) with a stop unit (38) which axially sliding in a body (18) oppositely to a compression spring (36). The gears (49, 51) are symmetric and are insertable into each other with a predetermined elastic resistance by the action of compression or loosing torque. The device is embodied in one piece which is mounted by assembling with the nut without effecting the spigot ends (2, 3). The device is used for locking a coupling in a systematic manner and makes it possible to unlock it without any preliminary voluntary operation.

  • Publication number: 20060065889
    Abstract: An organic electronic layer is formed using a monomer dissolved in a solvent such as formic acid. The solution is oxidized with the aid of an oxidizing agent, chosen such that there are no ionic byproducts resulting therefrom. Additives such as polyacids, acids, salts and electrolytes may be added to the solution.

  • Patent number: 6963081
    Abstract: In an embodiment of the invention, an electronic device includes an interfacial layer with traps. This interfacial layer is between an electrode and an organic layer, and if the electrode was adjacent to the organic layer, the energy barrier between these two layers is such that the current through the organic layer is limited by charge injection into this layer rather than the transport properties of the organic layer. The traps are used to accumulate charges of one charge type (e.g., either electrons or holes) within the interfacial layer. By accumulating charges, the bands of the interfacial layer are bent so that charges can tunnel from the electrode to the organic layer thus increasing the efficiency of the electronic device and allowing organic layers to be used within an electronic device that otherwise would be too inefficient for use in that device.

  • Patent number: 6954300
    Abstract: The present invention relates to electrochromic polymeric solid films, manufacturing electrochromic devices using such solid films and processes for making such solid films and devices. The electrochromic polymeric solid films of the present invention exhibit beneficial properties and characteristics, especially when compared to known electrochromic media. The electrochromic polymeric solid films are transformed in situ from a low viscosity electrochromic monomer composition by exposure to electromagnetic radiation, and in so doing minimum shrinkage occurs. The electrochromic polymeric solid films of the present invention also perform well under prolonged coloration, outdoor weathering and all-climate exposure, and provide an inherent safety aspect not known to electrochromic media heretofore.

  • Publication number: 20050069727
    Abstract: The position of the recombination zone can be controlled by controlling the mobility of the charge carriers. In an embodiment of the invention, the mobility of the charge carriers within the emissive polymer layer is controlled by the addition of traps—either electron traps, hole traps, or electron/hole traps. The electron traps reduce electron mobility, the hole traps reduce hole mobility, and the electron/hole traps reduce both electron mobility and hole mobility. The electron mobility and/or the hole mobility can be altered using the traps so that the recombination zone is positioned in the emissive polymer layer sufficiently far from the cathode so that quenching is minimized, and sufficiently far from the HTL/emissive polymer layer interface so that lifetime and/or efficiency is improved.

  • Publication number: 20050048314
    Abstract: In one embodiment of an OLED device, a hole injection/transport layer is added to the device structure in order to increase the number of holes injected into the emissive layer and reduce the number of electrons injected into the added hole injection/transport layer. In a first configuration of the added hole injection/transport layer, the added hole injection/transport layer is comprised of a non-doped hole transporting material that has an IP range between the highest IP value of the adjacent layer on the anode-end and the lowest IP value of the adjacent layer on the “emissive layer”-end. Optionally, in addition, nearly all electron affinities of the added hole injection/transport layer are less than the lowest electron affinity of the adjacent layer on the “emissive layer”-end. In a second configuration of the added hole injection/transport layer, this layer is formed by doping the hole transport material. The dopant is able to abstract electrons from the hole transporting material.

  • Publication number: 20040189195
    Abstract: Methods for protecting circuit device materials, optoelectronic devices, and caps using a reflowable getter are described. The methods, devices and caps provide advantages because they enable modification of the shape and activity of the getter after sealing of the device. Some embodiments of the invention provide a solid composition comprising a reactive material and a phase changing material. The combination of the reactive material and phase changing material is placed in the cavity of an electronic device. After sealing the device by conventional means (epoxy seal for example), the device is subjected to thermal or electromagnetic energy so that the phase changing material becomes liquid, and consequently: exposes the reactive material to the atmosphere of the cavity, distributes the getter more equally within the cavity, and provides enhanced protection of sensitive parts of the device by flowing onto and covering these parts, with a thin layer of material.
