  • Publication number: 20090174627
    Abstract: A plasma display, a driver for the plasma display, and a driving method thereof apply a reset minimum voltage according to a detected temperature of the plasma display. In the driving method, a reset falling waveform gradually decreasing to a reset minimum voltage is applied to a scan electrode during a falling period of a reset period, and a scan voltage is applied to the scan electrode selected during an address period. An address period is started the voltage applied to the scan electrode reaches the reset minimum voltage. In addition, a voltage difference between the reset minimum voltage and the scan voltage is determined according to a temperature of the plasma display.

  • Publication number: 20090121976
    Abstract: Wall charges of a turn-off cell selected from among a plurality of discharge cells are erased by applying an address voltage to a third electrode corresponding to the turn-off cell in an address period, and first and second pulse strings are respectively applied to first electrodes and second electrodes in a sustain period, where the first pulse string alternates between a first voltage and a second voltage higher than the first voltage, and the second pulse string has the same pattern as, but a different alternating timing from, the first pulse string. The sustain period includes an overlapping duration in which voltages of the first and second pulse strings are simultaneously higher than the first voltage.

  • Publication number: 20090085841
    Abstract: A plasma display, a controller therefor and a method of driving determines a total number of sustain pulses according to a screen load ratio, and allocates sustain pulses to each subfield according to a weight value of that subfield. A ratio of overlap sustain pulses to non-overlap sustain pulses is determined according to the weight value of each subfield, and the overlap and non-overlap sustain pulses are arranged according to the determined ratio. The arranged sustain pulses are applied to a plurality of first and second electrodes that perform a display operation during a sustain period.

  • Publication number: 20090009499
    Abstract: A plasma display, a controller therefor and a method of driving determines a screen load ratio from a plurality of video signals input during one frame, and determines a total number of sustain pulses according to the screen load ratio. A ratio of overlap sustain pulses to non-overlap sustain pulses is determined according to a first load ratio, and the overlap and non-overlap sustain pulses are arranged according to the determined ratio. The first load ratio may be the screen load ratio or a display load ratio. The arranged sustain pulses are applied to a plurality of first and second electrodes that perform a display operation during a sustain period.
