Abstract
A method and circuit for driving scan line in plasma panel is disclosed for dividing scan line of n-numbered cathode in two such that left side of scan line is constructed as a first group of even numbered cathode, and right side of scan line is as a second group of odd numbered cathode. There is provided a separate cathode driver and signal generation and processing portion with both first and second group of cathode. One picture of plasma panel is driven with two fields in an interlacing manner in that the conventional scanning frequency of 60 Hz is divided in two.
