ABSTRACT:
A flat CRT display tube has a faceplace (11) with a fluorescent pixel screen (33) on its interior face. An area cathode assembly has an orthogonal array of segment electrodes (27) with overlying heater wires (25) spaced above them. A control assembly (38) arrayed between the cathode assembly and the screen includes orthogonal arrays of row electrodes (20) and column electrodes (21) with an overlying anode (19). A frame (18) supports the cathode assembly and the control assembly, and is itself supported by the tube's envelope, preferably by its faceplate (11).
