  • Patent number: 7999766
    Abstract: A driving method and a driver circuit for improving the definition of display image on a plasma display device. In an initial state in an addressing discharge period, a scanning electrode is applied with a scanning base pulse at a first power supply potential. This suppresses a weak erroneous discharge between a scanning base pulse and a display data pulse. Next, the scanning electrode is applied with a scanning pulse. After the scanning pulse has been applied, the scanning electrode is applied with the scanning base pulse at a second power supply potential. In this way, the level of the scanning base pulse applied to the scanning electrode after the end of the application of the scanning pulse in the addressing discharge period is lower than the level of the scanning base pulse applied to the scanning electrode before the application of the scanning pulse.

    Abstract: A plasma display is provided with a plasma display panel, data drivers which apply data pulse to data electrodes of the plasma display panel, a control circuit which t controls an operation of the data drivers based on a video signal, and a protection signal output circuit. The protection signal output circuit outputs a protection signal to the control circuit when sum of currents supplied from the data drivers to the data electrodes within a time equal to one sub-field or more to less than one frame exceeds a previously set first specified current value. The protection signal restrains the operation of the data drivers.

  • Patent number: 6995521
    Abstract: Two sustain driver circuits are provided: a first sustain driver circuit for both controlling the potential on the scan electrode side and effecting control such that, when the scan electrode side is at the power-supply potential, this potential is used to raise the potential on the sustain electrode side; and a second sustain driver circuit for both controlling the potential on the sustain electrode side and effecting control such that, when the sustain electrode side is at the power-supply potential, this potential is used to raise the potential of the scan electrode side. When the scan electrode side is at the power-supply potential, control is effected such that current flows from the first sustain driver circuit to the second sustain driver circuit by way of a third switching element and first coil, whereby the potential of the scan electrode side falls and the potential of the sustain electrode side rises.
