Field emission digital display tube with nano-graphite film cathode
Abstract
The field emission digital display tube with a nano-crystalline graphite cold cathode is designed and fabricated. Under the control of the driving circuits, a dynamic digital display with uniform luminance distribution is realized. The luminance of the character segments is 190 cd/m2 at the operating voltage of 900 V. And the stable emission is attained with a fluctuation of about 3% at an average segment current of 75 \muA. The results demonstrate that nano-crystalline graphite film is a promising material for cold cathode.
