A Study on the Characteristics of Space Charge for the Plasma Display |
| Abstract |
To analyze the driving principle of PDP, the influence on the discharge characteristics of space charge was researched. Space charge generated by the priming discharge shortens delay time of the discharge which happens as follows and shortens response time. Such influences are valid up to about 30㎲ after generating priming discharge. This space charge decreases dicharge ignition voltage of the cell near priming cell and the influences are most greatly exerted on the discharge of cell which is adjacent most. And the dependency to space charge strengthens because discharge ignition voltage drop grows by narrowing of discharge pulse width. But the influence on space charge was observed very slightly in pulse width 1㎲ or more. Therefore, to cause a steady discharge, pulse width should become 1㎲ or more at least without being influenced for space charge of the adjoining discharge. |
