Abstract (en)
[origin: WO0067286A1] A cathode ray tube includes an electron gun directing electrons towards a faceplate having an electrode biased at screen potential. The electron beam is magnetically deflected to scan across the faceplate to impinge upon phosphors thereon to produce light depicting an image or information. An electrode between the tube neck and the faceplate is biased at or above screen potential. As a result, the electrons of the electron beam are additionally deflected electrostatically so that a greater total deflection is obtained than is provided by the magnetic deflection yoke. Another electrode proximate the faceplate is biased at or below screen potential to direct electrons towards the faceplate, thereby to increase the landing angle of the electron beam thereon.
