Abstract:
1. A plasma display device having a plurality of cells for displaying an image, the plasma display device comprising: a plurality of first electrodes; a first transistor having a first terminal electrically coupled to the plurality of first electrodes and a second terminal electrically coupled to a first power source for supplying a first voltage; a second transistor having a first terminal electrically coupled to the plurality of first electrodes; a first capacitor having a first terminal electrically coupled to the second terminal of the first transistor and a second terminal electrically coupled to a second terminal of the second transistor; a third transistor having a first terminal electrically coupled to the second terminal of the first capacitor and a second terminal electrically coupled to a second power source for supplying a second voltage; a fourth transistor having a first terminal electrically coupled to the second terminal of the first capacitor and a second terminal electrically coupled to a third source for supplying a third voltage; and a controller for controlling the first, second, third and fourth transistors during a subfield comprising a first period, a second period, a third period, a fourth period and a fifth period, such that the first transistor is turned on during the first period, the second and fourth transistors are turned on during the second period, the first and third transistors are turned on during the third period, the second and fourth transistors are turned on during the fourth period, and the third and second transistors are turned on during the fifth period.
