Here's some references from Randall Logan's site: http://www.scientificsolutions.ca/patents.htm
http://www.scientificsolutions.ca/Display%20Patents/Edge%20Lit/US2751584.pdf A single lit plate, such as an "exit" sign, goes back to 1914, but the multiplate 10 numeral digit, was applied for, in 1954. That, however, was in the U.S. It doesn't address patents in other countries. Does anyone here know when edge-lit displays were introduced? > There are two Swedish computer consoles, allegedly built in > 1953 and 1956, which use these. Could you buy edge-lit hexadecimal > digit displays as a component back then? Or were these fitted > later? Or were they home-built? > > -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
