| Abstract |
The variation of discharge characterstics of an ac PDP was observed with the change of scan electrode driving circuit. Conventional scan electrode driving circuit provides two switches per one scan line, and the suggested one can be constituted by one switch per one scan line with the consideration of capacitive load characteristic of an ac PDP. To verify the workability of the suggested scheme, the performances of the ac PDP was investigated. The dynamic voltage margin was slightly decreased with the adoption of the suggested scheme, which is estimated to result from the misfiring of unselected discharge cells due to the deformation of voltage level of the neighboring scan electrode. In the observation of the delay characteristics of addressing discharge, the performances of the conventional circuit and the suggested one are assumed to be equivalent. |
