Patent ID: 8669921

Claim:
A plasma display apparatus comprising: a plasma display panel including a scan electrode and a sustain electrode that are positioned parallel to each other; and a driver that allows a change amount of a voltage difference between the scan electrode and the sustain electrode in a reset period of a subfield during a pattern hold mode in which a pattern of input video data remains in a previous pattern to be different from a change amount of a voltage difference between the scan electrode and the sustain electrode in a reset period of a subfield during a pattern change mode in which the pattern of the video data changes, wherein, when a voltage difference between the scan electrode and the sustain electrode in a reset period of a first subfield of a first frame of a plurality of frames is a first value, a voltage difference between the scan electrode and the sustain electrode in a reset period of a first subfield of a second frame following the first frame is a second value, a voltage difference between the scan electrode and the sustain electrode in a reset period of a first subfield of a third frame following the second frame is a third value, and a voltage difference between the scan electrode and the sustain electrode in a reset period of a first subfield of a fourth frame following the third frame is a fourth value, a difference between the first value and the second value is greater than a difference between the second value and the third value and a difference between the third value and the fourth value, wherein a data change amount between the first frame and the second frame is greater than a critical change amount, wherein a data change amount between the second frame and the third frame is less than the critical change amount, wherein a data change amount between the third frame and the fourth frame is less than the critical change amount, wherein a peak voltage of a reset signal applied to the scan electrode during the reset period of the first subfield of the first frame is referred to as a first voltage, wherein a peak voltage of a reset signal applied to the scan electrode during the reset period of the first subfield of the second frame is referred to as a second voltage, the second voltage being greater than the first voltage, wherein a peak voltage of a reset signal applied to the scan electrode during the reset period of the first subfield of the third frame is referred to as a third voltage, the third voltage being less than the second voltage, and wherein a peak voltage of a reset signal applied to the scan electrode during the reset period of the first subfield of the fourth frame is referred to as a fourth voltage, the fourth voltage being less than the third voltage.
