Patent ID: 7136033

Claim:
A method of driving a 3-electrode plasma display apparatus, the method comprising: converting an external analog video signal into a digital signal to generate an internal video signal; generating drive control signals at a controller in response to the internal video signal; processing an X-drive control signal output from the controller and applying the result of said processing of the X-drive control signal to X-electrode lines; processing a Y-drive control signal output from the controller and applying the result of said processing of the Y-drive control signal to Y-electrode lines; processing an address signal at an address driver to generate display data signals and applying the display data signals to address electrode lines, the address signal being output from the controller, the apparatus including a 3-electrode plasma display panel, with the panel including the X-electrode lines, Y-electrode lines, and address electrode lines, the X-electrode lines and Y-electrode lines being alternately arranged in parallel on a rear surface of a front transparent substrate to form XY-electrode line pairs, the address electrode lines being arranged on a front surface of a rear transparent substrate to cross the XY-electrode line pairs, with intersections of the XY-electrode line pairs and the address electrode lines defining display cells; predicting a first addressing power of the plasma display panel during a non-operation of a power recovery circuit and operating the power recovery circuit when the first addressing power exceeds a first predetermined reference value; predicting a second addressing power of the plasma display panel during an operation of the power recovery circuit and not operating the power recovery circuit when the second addressing power exceeds a second predetermined reference value; collecting excess charges remaining in the display cells upon said operation of said power recovery circuit at the end of said applying the display data signals, said collecting excess charges being performed by said power recovery circuit; and applying the collected charges to the display cells upon said operation of said power recovery circuit at the start of said applying the display data signals.
