ABSTRACT:
A flat display screen comprises a microtip cathode for electronically bombarding an anode including at least two groups of alternate conductive strips with phosphor strips and a control circuit adapted to sequentially address each group. The control circuit includes means for applying, at least temporarily, to each group of conductive strips a voltage lower than the minimum biasing voltage of the cathode's microtips.
