Abstract
A plasma display apparatus wherein the unevenness in intensity between the electrode lines of a plasma display panel is reduced. In a plasma display apparatus, the temperature difference between the output elements of electrode drive circuits of a plurality of electrode groups is determined, and then a control signal, which is generated in accordance with the determined temperature difference, is used to control the gas discharge currents, which flow into a plurality of electrode groups, for example, odd-numbered electrodes and even-numbered electrodes, in such a manner that they are uniformly supplied, thereby preventing the unevenness in intensity between the electrode line.
