Abstract

A PROJECTION DISPLAY COMPRISES THREE CATHODE RAY TUBES EACH HAVING A DEFELECTION YOKE AND CONVERGENCE YOKE AND EACH TUBE GENERATING A RASTER FOR PROJECTION. ONE OF THE THREE CATHODE RAY TUBES HAS THE CONVERGENCE YOKE COUPLED FOR CURRENT FLOW IN A DIRECTION OPPOSITE TO THAT OF THE OTHER TWO CONVERGENCE YOKES. AN AMPLIFIER IS RESPECTIVELY COUPLED TO EACH CONVERGENCE YOKE FOR CONVERGENCE CORRECTION OF EACH RASTER. A CONVERGENCE CIRCUIT SUPPLIES CORRECTION SIGNAL VALUES THAT ARE COUPLED TO EACH RESPECTIVE AMPLIFIER SUCH THAT CONVERGENCE CORRECTION BY THE OTHER TWO CONVERGENCE YOKES IS RESPONSIVE TO A DIFFERENCE BETWEEN THE CORRECTION SIGNAL VALUE COUPLED TO THE ONE CONVERGENCE YOKE AND THE CORRECTION SIGNAL VALUES COUPLED TO THE OTHER TWO CONVERGENCE YOKES.
