Patents by Inventor Dmitry Kolosov

Dmitry Kolosov has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8264157
    Abstract: An electronic device can include an organic diode and a shunt that allows a significant current to bypass the organic diode, wherein the shunt is separate from the organic diode. Alternatively, an electronic device can include an organic diode lying along a first conduction path. The electronic device can also include a resistive member lying along a second conduction path that is parallel to the first conduction path. In another aspect, a process of forming an electronic device can include forming a first conductive member, forming a resistive member over the first conductive member, and forming an organic semiconductor layer over the first conductive member. The process can also include forming a second conductive member over the resistive member and the organic semiconductor layer, such that the resistive member and the organic semiconductor layer lie along parallel conduction paths between the first and second conductive members.

  • Patent number: 8040048
    Abstract: A process of forming an electronic device is disclosed. An organic device layer is formed. The organic device layer includes a charge-selective material and a radiation sensitizer and has a first electrical conductivity and a first surface energy. First portions of the organic device layer are selectively exposed to radiation. The electrical conductivity and surface energy of the first portions of the organic device layer are modified.

  • Patent number: 7474115
    Abstract: Defects are detected in organic electronic device displays such as organic light emitting diode (OLED) displays. An infrared camera may be used to screen displays for defects and to identify the locations of the defects. Relative hot or cold areas in a display correspond to defects and can be detected using the infrared camera.
