ABSTRACT:
A cathode ray tube display with scanning beam velocity modulation comprises a cathode ray tube with a neck and gun for generating an electron beam. A deflection yoke is mounted on the cathode ray tube for electron beam deflection. A first flexible support having a side for conductor fabrication and a second flexible support having a side for conductor fabrication are superimposed and wrapped to conform to the neck circumference. A first coil pattern is formed as a conductor on the first conductor fabrication side and a second coil pattern is formed as a conductor on the second conductor fabrication side. A conductive connection couples between the first coil pattern and the second coil pattern. A connector couples scanning velocity modulation current to energize said first coil pattern and said second coil pattern for scanning beam velocity modulation.
