Abstract
A flat panel display includes cathode columns with microtips for emitting electrons, arranged in gate rows, and an anode provided with phosphor elements arranged in groups of juxtaposed strips, electrically insulated one from the other. The intersection of a gate row and of a cathode column defines a pixel of the display. The groups of anode strips are electrically connected to form two networks. A first network includes groups of strips of odd rank, while the second network includes the groups of strips of even rank. The flat panel display further includes an electronic control system adapted to sequentially address the groups of odd rank, and even rank, respectively.
