Patent ID: 8253656

Claim:
A plasma display apparatus comprising: a plasma display panel comprising scan electrodes and sustain electrodes; a sensor unit for detecting a temperature or a peripheral temperature of the PDP; and a scan driver for supplying reset signals to the scan electrodes in a reset period of at least one subfield among a plurality of subfields at a predetermined reference temperature so that a first period in which a lowest voltage of the reset signal is supplied is different from a supply period of a lowest voltage when the temperature or the peripheral temperature of the PDP deviates the predetermined reference temperature, wherein: when the temperature or the peripheral temperature of the PDP is comprised in the reference temperature, maintenance periods in which the lowest voltage of the reset signals are supplied in reset periods of the first subfields are referred to as first maintenance periods and maintenance periods in which the lowest voltage of the reset signals are supplied in reset periods of the second subfields are referred to as second maintenance period, and when the temperature or the peripheral temperature of the PDP is higher than the reference temperature, maintenance periods in which the lowest voltage of the reset signals are supplied in reset periods of the first subfields are referred to as third maintenance periods and maintenance periods in which the lowest voltage of the reset signals are supplied in reset periods of the second subfields are referred to as fourth maintenance periods, the first maintenance periods and the third maintenance periods are the same and the second maintenance periods are longer than the fourth maintenance period.
