Abstract:
1. A driving method of a plasma display, the plasma display comprising a plurality of discharge cells and being driven with one frame divided into a plurality of subfields respectively having weight values, the driving method comprising: discharging the plurality of discharge cells during a first period of a sensing period in at least one subfield of the plurality of subfields; initializing the plurality of discharge cells during a second period subsequent to the first period of the sensing period; selecting light emitting cells among the plurality of discharge cells through address discharge during an address period subsequent to the sensing period; performing sustain discharge in the light emitting cells for a number of times corresponding to a weight value of a corresponding one of the subfields during a sustain period subsequent to the address period; and identifying a contact with the plasma display based on light generated from the discharge cells during the sensing period.
