摘要：
The source includes columns (4) emitting electrons and lines (6) whose potential evolves up to a positive value Vl. The screen also includes at least one additional column (24) common to all the lines, means (28) to bring this additional column to a negative potential so that, irrespective of the potential of the lines it crosses, electrons may be emitted in the crossing zones, at least one additional anode (26) opposite the additional column, and means (30) to bring this additional anode to a positive potential of less than Vl. Each line is controlled by a single output transistor (32) which brings it to Vl when it is activated and disconnects it from the voltage source Vl when it is disactivated. Application for microtip screens.
