Patent ID: 7564431

Claim:
A method for reducing power consumption of a plasma display panel (PDP), the PDP comprising a first switch selectively allowing electrical charges to flow from a first voltage source to a first terminal of the PDP, a second switch selectively allowing electrical charges to flow from the first terminal of the PDP to ground, a third switch selectively allowing electrical charges to flow from a second voltage source to a second terminal of the PDP, a fourth switch selectively allowing electrical charges to flow from the second terminal of the PDP to ground, a first recovery capacitor with a first terminal coupled to ground, a fifth switch selectively allowing electrical charges to flow from a second terminal of the first recovery capacitor to the first terminal of the PDP, a sixth switch selectively allowing electrical charges to flow from the first terminal of the PDP to the second terminal of the first recovery capacitor, a second recovery capacitor with a first terminal coupled to ground, a seventh switch selectively allowing electrical charges to flow from a second terminal of the second recovery capacitor to the second terminal of the PDP, and an eighth switch selectively allowing electrical charges to flow from the second terminal of the PDP to the second terminal of the first recovery capacitor; the method comprising: turning on the second switch and turning off the first, third, fourth, fifth, sixth, seventh, and eighth switches for a first period; turning on the third and fifth switches and turning off the first, second, fourth, sixth, seventh, and eighth switches for a second period; turning on the fifth and eighth switches and turning off the first, second, third, fourth, sixth, and seventh switches for a third period; and turning on the first, fifth, and eighth switches and turning off the second, third, fourth, sixth, and seventh switches for a fourth period.
