Abstract

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 1 000 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 feedback for field emission current

and the illuminant uniformity of CNT-FED is improved effectively. The driving circu

it 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 1 400 cd/m
