Abstract
A cathode ray tube comprising an electron gun having two oppositely arranged conductor patterns. In operation, the electron beams (or electron beam) move between the conductor patterns. It has been found that the electron-optical functions, such as focusing and converging the electron beams, which are fulfilled by electrodes in a conventional gun can be fulfilled by two flat-conductor patterns. Said conductor patterns can be accurately manufactured and arranged relative to each other. This enables the manufacture of complicated lens systems.
