Abstract
A plasma display device is disclosed. The plasma display device includes a plasma display panel having a display area and a non-display area, driving circuits, comparator control circuits, and heating elements mounted on the non-display area of the plasma display panel. The non-display area surrounds the display area. A part of the driving circuit and a corresponding heating element may be a Wheatstone bridge circuit. Each comparator control circuit is coupled to the Wheatstone bridge circuit so as to control the heating element. When a portion of the display area is lit, a heating element located on the adjacent non-display area is then activated through the current balance of the Wheatstone bridge circuit and under the control of the driving circuit and the comparator control circuit. Thus, the temperature difference between the display area and the non-display area is reduced.
