Abstract: A driving circuit for a gaseous discharge display device comprises a processing circuit for processing data signals and clock signals and a data input counter connected in parallel and a scanning control circuit connected to the data input counter to control the turning on and off of scan operations so that unnecessary power consumption can be reduced and the contrast ratio enhanced by preventing auxiliary discharge effects from occurring when no data is input for display at the gaseous discharge display device.

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.

Abstract: A color plasma display device for preventing phosphor sputtering phenomenon and the image spread phenomenon. The phosphor coating layer is separated by a transparent insulating layer from the gas discharge space by sequentially positioning the phosphor material coating layer. A black layer containing holes therein and a transparent insulating layer below an upper glass substrate.
