Abstract:
1. A plasma display apparatus comprising: a plasma display panel including a scan electrode, a first address electrode and a second address electrode; a data driver initiating a change in a voltage value of a first data signal supplied to the first address electrode at a first initiation time and initiating a change in a voltage value of a second data signal supplied to the second address electrode at a second initiation time, with each of the data signals gradually changing from a first data voltage to a second data voltage during a respective first period, maintaining at the second data voltage during a respective second period, and gradually changing from the second data voltage to the first data voltage during a respective third period; and a scan driver initiating a change in a voltage value of a scan signal supplied to the scan electrode at a third initiation time, wherein the data driver includes: wherein the first switch is turned on while each of the data signals are applied, and the second switch is turned off while each of the data signals are applied, wherein the detected load of the first address electrode or the second address electrode is proportional to a switching frequency at which the first switch and the second switch are turned on or turned off, wherein the first initiation time is substantially the same as the second initiation time when the detected load is within the first load range, and the first initiation time is earlier than the second initiation time when the detected load is within the second load range, wherein, when the detected load is within the second load range, a time interval between the first initiation time and the second initiation time is less than or equal to a duration of the first period for the first data signal, and wherein the third initiation time is earlier than the first and second initiation times.
