Abstract: | A new plasma display panel driving method was proposed to reduce the address period. The scan time of the address method using overlapping scan time overlaps with the next scan time during the formative lag time of the discharge. Thus, without reducing the address pulsewidth and the scan pulsewidth, the driving method can reduce the address period. We could overlap the scan time of about 100 /spl sim/300 ns. However, the driving method has a narrow address voltage margin compared with a conventional method. In order to improve the address voltage margin of the driving method, the scan direction is set to the opposite direction compared with the conventional direction. As shown in experimental results, the address voltage margin of the new driving method is increased by 7/spl sim/10 V when the opposite scan direction is used. |
