Zusammenfassung:	The fluorescent vacuum display unit for alpha-numeric symbols in seven-segment format, is based upon a modular construction that permits a large number of characters to be represented in a compact unit. The display module is based upon a frame (1) that provides a housing for a cathode, control electrode and display screen. The open ended frame provides a location for a rectangular control electrode that has tabs locating in recesses (2). A slot (4) and hole provide locations for the cathode wire holders. The display screen is bonded to the frame. Modules may be mounted side by side and secured with dowels locating in semi-circular grooves (6).
