A multicolor visual display apparatus for stereophonic sound signals is disclosed. The display apparatus includes a conventional three gun color cathode ray tube, having a screen with a plurality of colored phosphor dot triads. Stereophonic signals are coupled to a deflection yoke located on the neck of the tube for producing a pattern on the screen in sympathy with the information content of the channels. The convergence coils and purity rings normally located at the rear of the yoke on a three gun color tube neck are not used. Their absence permits the location of the deflection yoke behind its normal position whereby electrons from any of the guns strike phosphor dots of different colors in different regions of the screen, producing a pleasing multicoloration of the pattern. A coil in the nature of a standard degaussing coil is activated while the pattern is displayed to further enhance this multicoloration.
An apparatus for displaying colored aesthetic patterns of the information in two random electrical signals comprising:
An apparatus for displaying colored aesthetic patterns of the information in two stereophonic electrical signals comprising:
An apparatus for displaying colored aesthetic patterns in response to first and second sources of random, non-periodic information signals, comprising a source of said signals, a cathode ray tube having a multicolor screen including a multiplicity of phosphor regions dispersed across the entire screen, each of said regions including plural phosphor segments of different colors, said tube further including an electron beam gun for producing a beam of electrons adapted to strike the screen, means responsive to the first and second signals for respectively deflecting the electron beam across the screen in first and second mutually orthogonal directions, and means for controlling trajectories of the electron beam between the gun and the screen so that the electron beam strikes phosphors for all of the colors while the beam is being deflected in response to the signals.
An apparatus for displaying colored aesthetic patterns in response to a pair of random, non-periodic signals, comprising a source of said signals, a cathode ray tube having a multicolor phosphor screen including a multiplicity of phosphor regions dispersed across the entire screen, each of said regions including plural phosphor segments of different colors, said tube further including an electron beam gun for producing an electron beam adapted to strike the screen, means responsive to the signals for deflecting the electron beam across the screen, and magnet means for controlling the trajectories of the electron beam between the gun and the screen so that the electron beam strikes phosphors for all colors while the beam is being deflected in response to the signals.
