Abstract

1302645 Matrix displays INTERNATIONAL STANDARD ELECTRIC CORP 19 April 1971 [16 Feb 1970] 21553/71 Heading G5C An alpha-numeric display device comprises a plurality of selectively activated segments arranged on or adjacent the sides, centre lines and diagonals of an approximately non- rectangular parallelogram, there being a plurality of segments on each side and centre line, a circular segment at the centre of the parallelogram and curved segments extending approximately along the diagonals, preferably forming parabolas tangential at the centre. With this arrangement of segments the failure of one segment can be detected and the possibility of one character appearing as another due to such a failure is prevented. The device comprises a metal die casting having an array of chambers in the form of the segments each containing an incandescent lamp and covered with a frosted sheet. The lamps are mounted on a printed circuit board and are directly switched by integrated circuits including shift registers or their brightness is controlled by amplifiers.
