P‐60: Reset Waveform for Dark‐Room Contrast‐Ratio Improvement

Abstract

In this paper, we propose the new reset waveform which shows high dark‐room contrast‐ratio and robustness for cross talk. We apply a ramp pulse to the address electrode after the erase X ramp pulse. And a constant bias voltage is applied to X electrode during the Y rising‐falling ramp and the address period. Using this method, we achieved a great dark‐room contrastratio 2750:1. However, the address minimum voltage was increased about 17∼37V compared with the conventional ramp reset method. We could reduce the minimum address voltage through the waveform optimizing. As a result, when VSB is −30V, we could reduce the address minimum voltage about 14∼28V and improve the dark‐room contrast‐ratio3000:1.
