Cathode ray tube device for display system

摘要

Each of picture elements on a color display system is formed of a triad of small monochromatic cathode ray tubes luminescing in red, green and blue in response to unfocused electron beams from respective electron guns and disposed in a cylindrical housing. The tubes include identical components interconnected through respective leads extending externally of the housing. Alternatively, the housing may additionally include a driving source having a high voltage generator for applying an anode voltage to the tubes and leads extending externally of the housing which serve to energize the generator and tube heaters and to apply control signals to the tubes.
