Abstract: A large metal cone cathode ray tube and envelope for the same in which the faceplate is adhered to the metal cone by a frit seal without distorting the faceplate. In some embodiments, a glass neck assembly also is adhered to the metal cone by a frit seal. Readily available glass and metal materials can be used.

Abstract: A cathode ray tube display system apparatus and method in which a memory stores the addresses necessary to cause the electron beam of a cathode ray tube to impinge upon predetermined locations on the cathode ray tube screen. A single beam electron gun can thus selectively activate different types of phosphors in an array of phosphor locations to produce, for example, a multicolor display. An apparatus and method in which a memory stores addresses necessary to cause images to be projected at predetermined locations in a cathode ray tube projection display system.
