  • Patent number: 9240782
    Abstract: A touch sensitive device includes a capacitive touch panel with plural electrodes, a driving and sensing circuit electrically connected to the electrodes through sensing lines, and at least one conductive member. The conductive member is arranged orthogonal to and crosses the sensing lines without contact and is electrically connected to the driving and sensing circuit. Therefore, a stable coupling capacitance is provided for a one dimensional capacitive touch panel for improved touch sense performance.

  • Patent number: 8164563
    Abstract: A liquid crystal display device includes a gate driver for generating a first scan signal voltage and a second scan signal voltage, a source driver for generating a first polarity data voltage and a second polarity data voltage, and a liquid crystal display panel having a first pixel set and a second pixel set. Each first and second pixel set includes a first pixel and a second pixel. Both the first pixel of the first pixel set and the second pixel of the second pixel set display grey level based on the first polarity data voltage in response to the first scan signal voltage. Both the second pixel of the first pixel set and the first pixel of the second pixel set display grey level based on the second polarity data voltage in response to the second scan signal voltage.

  • Patent number: 7339554
    Abstract: A method for driving a cell of a plasma display panel in a duration of a frame, in which the frame contains a plurality of subfields. The method comprises setting a selected subfield in the frame of at least one cell of a scanning line to a selected state; setting each one of the subfields preceding the selected subfield to a state opposite the selected state; setting each one of the subfields succeeding the selected subfield in the frame to the same state as a corresponding subfield of a corresponding cell in an adjacent previous scanning line; and driving the one cell by turning the cell into either an ON or OFF condition from the selected subfield throughout the succeeding subfields in the frame based on the selected state of the selected subfield. Another method is to set each one of the subfields succeeding the selected subfield in the frame, based on states of corresponding subfields of corresponding cells in an adjacent previous scanning line and an adjacent next scanning line.
