Abstract:
A triode type cathode structure of an FED screen arranged in rows and columns, including a first lower metallization level forming cathodes, an electrical insulating layer, a second higher metallization level forming extraction grids, openings formed in the second metallization level and in the electrical insulating layer, and lines of electron emission arranged in the openings, which lines are parallel to the direction of the rows of the screen.
