ABSTRACT:
A structure for converging electrons at the screen of a flat panel display and for transversely scanning electrons across the channels of the display includes a plurality of conductive strips arranged between the acceleration mesh and the phosphor screen. The strips extend longitudinally along and are substantially parallel to the acceleration mesh and are also substantially parallel to one another. A first portion of the strips is voltage biased to converge electrons in the proximity of the screen and scan said electrons transversely across the channels and the other portion is voltage biased to scan the electrons transversely across the channels.
