 Occasionally I come across old gas plasma displays that I would like to use in projects.  Occasionally I come across old gas plasma displays that I would like to use in projects.

 +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 coloured pixels.

 +Nixie tubes have electrodes shaped into symbols (eg '1','2', '3') or multiple segments (like numeric LED displays).  Flat panel plasma displays have a matrix of cells that can be caused to discharge individually, and have electronics to drive columns of cells in a wave or scan across the panel, a bit like refreshing a CRT tube.
