ABSTRACT:
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 a device for controlling flow of electrons from the source through the corresponding channel in the magnet onto the target. Addressing device 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 device 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 device of each display element in a corresponding line of display elements.
