Overview Nixie tubes and some early flat panel monochrome screens both use similar technology. They rely on gases being excited into a plasma state by high voltage and emitting visible light. Later 'plasma' colour TV screens use a similar discharge to produce ultra-violet light that then excites coloured phosphurs (red/green/blue) to produce co… text/html 2021-06-15T19:46:11+12:00 http://projects.scorchingbay.nz/dokuwiki/electronic/plasma/td700?rev=1623743171&do=diff [TD 700] Plasma Display Description Model25537466-CManufacturerBurroughsRecovered fromBurroughs TD 700 terminalCols32Rows8Character matrix5×7Pixels ColourOrangeDriver IC7475ConnectorPCBNum Pins2 x 18Pin spacing0.1” Resources * [TD700 TD800 reference manual July 1973] * [Single register self-scan panel display theory of operation] * [Self scan panel displays] * [Easy scanning for gas discharge display panel] * [Application note], Self Scan panel display timing requirements * …
