Yoshihiro Ushigusa 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).

  • Publication number: 20040217927
    Abstract: Provided is an apparatus for driving a display panel. The apparatus includes a main display control unit, an icon display control unit, a dot-matrix display control unit, first and second oscillators, an icon driver, and a dot-matrix driver. While the first oscillator generates a first clock signal composed of pulses having a first frequency and supplies the same to the dot-matrix display control unit, the second oscillator generates a second clock signal composed of pulses having a second frequency that is lower than the first frequency and supplies the second clock signal to the icon display control unit.

  • Patent number: 6552703
    Abstract: A display apparatus using capacitive light emitting devices, in which some of a plurality of driving lines are selected in a scanning period in predetermined cyclic period consisting of the scanning period and a resetting period subsequent thereto, current sources are connected to the selected driving lines, and a current in the forward direction is supplied to each of the capacitive light emitting devices between the selected driving lines and a selected one scanning line, and in the resetting period, a same electric potential is applied to driving lines to be selected for a next scanning period and all of the plurality of scanning lines, thereby discharging charges of the capacitive light emitting devices between the driving lines to be selected and all of the scanning lines, wherein a length of the scanning period in the predetermined cyclic period is changed in response to a luminance information command, and the period other than the scanning period in the predetermined cyclic period is set to the resett

  • Publication number: 20010045918
    Abstract: A display apparatus having: an inputting device for inputting a first image signal generated for a first display device having a first coloring characteristic defined by a first color range shown in a chromaticity diagram; a converting device for converting the inputted first image signal into a second image signal for a second display device having a second coloring characteristic defined by a second color range shown in the chromaticity diagram, the second color range and the first color range are different from each other; a driving device for generating a driving signal on the basis of said second image signal; and the second display device for displaying an image on the basis of the driving signal.

  • Patent number: 6229267
    Abstract: Disclosed is a method for driving a display apparatus with capacitive light-emitting devices, which enables to suppress consumption power. The method includes the steps of; (1) selecting non-connection keeping drive lines among all of the drive lines which are not connected to the drive source in a previous scan period and a present scan period, in the reset period, connecting all of the scan lines to the same reset potential and connecting the selected non-connection keeping drive lines to the ground potential while connecting the other drive lines to the reset potential, or (2) selecting unconnected drive lines among all of the drive lines which are not connected to the drive source in a present scan period, in the reset period, connecting all of the scan lines to the same reset potential and connecting the selected unconnected drive lines to the ground potential while connecting the other drive lines to the reset potential.
