Abstract
A plasma display device includes the following elements: an image signal conversion circuit for converting an image signal into an image data; a data electrode driver circuit for driving data electrodes according to the image data; a power calculation circuit for calculating a power consumption of the data electrode driver circuit according to the image data; and a temperature calculation circuit for calculating a temperature of the data electrode driver circuit according to the image data. The image signal conversion circuit converts the image signal into an image data decreasing the power consumption of the data electrode driver circuit at least when the calculated power consumption exceeds a predetermined power threshold value, or when the calculated temperature exceeds a predetermined temperature threshold value.
