摘要：

To avoid the high driving voltage and illuminant non-uniformity of carbon nano-tube field emission display (CNT-FED) fabricated by silk screen-printed technology, a voltage controlled address display-period separation driving circuit is designed and implemented. Line and column driving wave are realized by adopting a separate high voltage controller and a reverse high voltage is applied to control turn-off pixels. The circuit not only satisfies the high driving voltage from 700 V to 1000 V for silk screen-printed CNT-FED, and also the crosstalk caused by leakage current is restrained. Current-limit resistance is presented on every line which serves as the feed-back for field emission current, and the illuminant uniformity of CNT-FED is improved effectively. The driving circuit has low cost, and luminance and uniformity of silk screen-printed CNT-FED is advanced from the point of circuits view. Tests results show that CNT-FED with the driving circuit can displays dynamic image and the peak luminance comes to 1400 cd/m2.
