Flat cathode ray tube and method of operation

摘要

A flat cathode ray tube and method of using characterized by an evacuated chamber being subdivided into a guidance space and post deflection space by a control plate having row electrodes or conductors on one side and column electrodes or conductors on the other side which column electrodes face a cathode-luminescent layer in the deflection space and a source for producing a flat electron beam being positioned at the side of the guidance space. In controlling the beam, a beam guidance electrode in the guidance space is utilized so that the beam will move in a sinuous path and strike each of the selected row conductors with the desired angle. To accomplish this feature, the wave length of the path of the flat beam for adjacent rows is changed so that the beam is deflected from the same position in the wave length.
