  • Publication number: 20070205409
    Abstract: There is provided a process for forming a contained second layer over a first layer, including the steps: forming the first layer having a first surface energy; treating the first layer with a reactive surface-active composition to form a treated first layer having a second surface energy which is lower than the first surface energy; exposing the treated first layer with radiation; and forming the second layer. There is also provided an organic electronic device made by the process.

  • Patent number: 7253444
    Abstract: A light-emitting unit containing a substrate and light emitting diodes (LEDs) is housed inside a casing constituted by a first member and a second member which are joined together. The second member has a projecting piece which is inserted to the first member, and inside the projecting piece a passage is formed. When silicone is injected through an injection opening from an injector, the silicone starting from the projecting piece flows through in the order of the passage, first-member side space, connecting passage and second-member side space and it finally overflows from a discharge opening. By implementing this structure and process, the air or air bubbles inside the light-emitting unit is pushed outside completely.

  • Publication number: 20070166871
    Abstract: Disclosed herein are NPN-type low molecular aromatic ring compounds, organic semiconductor layers formed from such compounds that exhibit improved electrical stability and methods of forming such layers using solution-based processes, for example, spin coating processes performed at or near room temperature. These NPN-type compounds may be used, either singly or in combination, for fabricating organic semiconductor layers in electronic devices. The NPN-type aromatic ring compounds according to example embodiments may be deposited as a solution on a range of substrates to form a coating film that is then subjected to a thermal treatment to form a semiconductor thin film across large substrate surfaces that exhibits reduced leakage currents relative to conventional PNP-type organic semiconductor materials, thus improving the electrical properties of the resulting devices.

  • Patent number: 7166860
    Abstract: An electronic device includes a substrate and a well structure overlying the substrate and defining an array of openings. From a cross-sectional view, the well structure, at the openings has a negative slope. From a plan view, each opening corresponds to an organic electronic component. Each opening within the array of openings has a width and two immediately adjacent openings within the array of openings are connected by a channel having a width smaller than the width of each opening.

  • Patent number: 7148076
    Abstract: A light emitting element having a superior light emitting characteristic is provided by forming a region partly including a phosphor (light emitting region) in manufacturing of a light emitting element having an organic compound layer using a high molecular weight material. A solution in which a high polymer having a degree of polymerization of 50 or more is dissolved in a solvent is applied by a spin coating method, and then a low polymer which is composed of the same repetition units as the high polymer and has a degree of polymerization of 2 to 5 and a phosphor are coevaporated to form a light emitting region (105) and only a low polymer is vapor-deposited on the light emitting region to form an organic compound layer (103). Thus, the light emitting region (105) can be partly formed.
