Field emission display with printable planar triode

The principle of field-emission display is almost the same as the traditional cathode ray tube, so it should display the image with the same quality as CRT. However, the triode structure and uniformity of field-emission is two key issues regarding the field-emission display. In this paper, a planar triode is discussed deeply. The structure of this planar triode is quite simple, and it can be fabricated cheaply with screen-printing method. A prototype has been made to verify the concept of the printable field-emission triode.
