Syuuki Yamamori 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).

  • Fluorescent lamp, fluorescent lamp unit, liquid crystal display device, and method of emitting light
    Patent number: 6917354
    Abstract: A liquid crystal display device has a fluorescent lamp and a driving circuit as a back light. A closed container, a discharge gas sealed in the closed container, first discharge electrodes, and second discharge electrodes are included in the fluorescent lamp. The driving circuit repeats a first step of causing electric discharge in first discharge areas by applying a voltage having a negative polarity to the first discharge electrodes and a voltage having a positive polarity to the second discharge electrodes, and a second step of causing electric discharge in second discharge areas which are different from the first discharge areas by applying a voltage having a positive polarity to the first discharge electrodes and a voltage having a negative polarity to the second discharge electrodes.
