Toshiyuki Hirase 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).

  • Electrooptic device, driving method therefor, electronic device, and projection display device
    Patent number: 7098880
    Abstract: The invention provides an electrooptic device that can include a first substrate on which pixel electrodes, first thin film transistors electrically connected to the pixel electrodes, and scanning lines and data lines electrically connected to the first thin film transistors are formed, a second substrate opposing the first substrate and having a common electrode, and an electrooptic substance held between the first substrate and the second substrate. The electrooptical device can further include a switching element for discharging in capacitors constituted by the pixel electrodes on the first substrate, the electrooptic substance, and the common electrode on the second substrate. The invention makes it possible to remove charges from inside the electrooptic device.
