ABSTRACT:
Picture display device having a vacuum envelope for displaying pictures composed of pixels on a luminescent screen, comprising a plurality of juxtaposed sources for producing electrons, local electron ducts cooperating with the sources and having walls of electrically insulating material with a secondary emission coefficient suitable for electron transport for transporting, through vacuum, produced electrons in the form of electron currents through juxtaposed trajectories at a short distance from the luminescent screen, and means for withdrawing each electron current at predetermined locations from its duct and directing it towards a desired location on the luminescent screen for producing a picture composed of pixels.
