Eidophor

"Theatre television" redirects here. For boxing theatre television, see Pay-per-view.

An Eidophor was a video projector developed in the 1940s, used to create theater-sized images from an analog video signal. The name Eidophor is derived from the Greek word roots eido and phor meaning 'image' and 'bearer' (carrier). Its basic technology was the use of electrostatic charges to deform an oil surface.
