Magnetic matrix display device and computer system for displaying data thereon

摘要

A display device having a cathode for emitting electrons and a permanent magnet. A two dimensional array of channels extends between opposite poles of the magnet. The magnet generates, in each channel, a magnetic field for forming electrons from the cathode into an electron beam. A screen receives an electron beam from each channel. The screen has a phosphor coating facing the side of the magnet remote from the cathode. The phosphor coating having a plurality of pixels each corresponding to a different channel and each having a plurality of different color sub-pixels. An electrode grid is disposed between the cathode and the magnet for controlling flow of electrons from the cathode into each channel. A plurality of anodes each disposed on the surface of the magnet remote from the cathode, each corresponding to a different channel, and each having a first and second anode respectively extending along opposite sides of the corresponding channel for accelerating electrons through the corresponding channel and for sequentially addressing electrons emerging from the corresponding channel to different sub-pixels of the corresponding pixel. The first and second anodes associated with each channel are skewed relative to the sub-pixels of the corresponding pixel.
