Abstract: In a display device a modulator structure may be formed by disposing on a surface of the back wall a plurality of first control electrodes. A modulator member having a smoothly continuous surface has disposed thereon a plurality of second control electrodes. The surfaces of the back wall and the top member having the electrodes thereon are joined together to form opposing pairs of control electrodes.

Abstract: An evacuated envelope includes spaced, substantially parallel front and back walls, and a plurality of spaced, parallel supports between the front and back walls and forming a plurality of channels. A gun structure at one end of the channels directs at least one beam of electrons along each channel. In each of the channels is at least one beam focusing guide which confines the electrons in the beams but allows the beam to be selectively deflected out of the guide toward a phosphor screen on the inner surface of the front wall. Each of the focusing guides includes spaced walls between which the electron beam passes. Between the gun structure and each of the focusing guides is a beam clean-up section. The beam clean-up section serves to remove from the beam those electrons whose position and velocity vector are such that they would impinge on a wall of its focusing guide during the travel of the electron along the guide.

Abstract: An evacuated envelope has a rectangular display section and a gun section at one edge of the display section. The display section includes front and back walls which are generally rectangular, in closely spaced, parallel relation, and a plurality of spaced, parallel support walls between the front and back walls forming a plurality of parallel channels. The gun section extends across one end of the channels and includes therein gun structure which will direct electrons into the channels. In each of the channels is a beam guide which confines the electrons in a beam and guides the beam along the length of the channel. The beam guide also includes means for selectively deflecting the electron beam out of the guide at selective points along the guide so that beam will impinge upon a phosphor screen along the inner surface of the front wall. In each of the channels is a scanning deflector which deflects the path of the beam as it passes from the guide to the phosphor screen so that each of the beams will scan a portion of the phosphor screen.
