DISPLAY SYSTEM

摘要

A display system comprises a display screen including a matrix of display elements and a permanent magnet having an array of channels formed therein. Each channel corresponds to a different display element. Each display element comprises a phosphor target, an electron source and means for controlling flow of electrons from the source through the corresponding channel in the magnet onto the target. Addressing means comprises first and second orthogonal conductors defining a grid. Each display element is located at the intersection of a different pair of first and second conductors. Each first conductor is connected to a first control electrode of the control means of each display element in a corresponding line of display elements and each second conductor is connected to a second control electrode of the control means of each display element in a corresponding line of display elements.
