A Study on the Discharge Characteristics of High Speed Addressing for the HDTV Class Plasma Display |
Abstract |
The discharge characteristics of 3 electrodes AC surface discharge plasma display were analyzed. For an unstable state of the discharge which appeared at the maximum discharge voltage, it is found that a partial erase of the wall charge by the second discharge is a cause. Based on the second discharge, new operation margin considering the interrelation between the address discharge and the display discharge was defined and the validity of it was verified by the experiments. It is necessary to decrease the address pulse width for high-speed addressing. However, the operation margin of the address pulse decreases as the pulse width of it becomes narrower. If the address pulse width is wider than 1[㎲], the operation margin of the display discharge is not related to the address pulse width. From the experimental result, image of 8bit 256 gray level was displayed on PDP with the cell structure of the HDTV class by using the high-speed address ADS drive method with pulse width of 1[㎲] and the brightness of 560[㏅/㎡] was obtained. |
