More Information
Summary:Picture display device having a vacuum envelope with a face plate whose inner side is provided with a luminescent screen having a repetitive pattern of triplets of red, green and blue-luminescing phosphor elements, a rear plate at a short distance therefrom and in the space therebetween a plurality of electron emitters and juxtaposed, electron ducts cooperating therewith and having walls of substantially electrically insulating material having a secondary emission coefficient suitable for electron transport for transporting, through vacuum, produced electrons in the form of electron currents. Means are provided for withdrawing each electron current at predetermined locations from its duct and for directing this current towards a desired location on the luminescent screen for producing a picture composed of pixels.
