World's First Plasma Display
In the 1960s, some physics professors led by Don Bitzer took the first steps down the road that would lead to the invention of the modern plasma display. He and his colleagues were looking to reduce the flickering inherent to standard cathode-ray tube displays, and their answer was to use three thin layers of glass, with the middle layer perforated with tiny holes filled with gas. The outer layers were lined metallic wires (so thin as to be invisible) that, when electrified, excited the gas. This was a completely new way to display images, which overcame the flickering by eliminating the need to refresh the image.
