Wild already in Current technologies include liquid-crystal display LCD and digital light processing DLP projectors, both of which produce superior results from easily portable devices. Advances in projection television technology in the s brought about the end of the Eidophor.ДЄn early prototype of a new type of projector with limited resolution using a passive matrix-addressed Liquid Crystal Display was shown at a conference in San Francisco by Swiss engineer Peter J. The last Eidophors were able to project colour images of up to 18 metres in width. The Eidophor was 80 times brighter than CRT projectors of the time. The last models produced used separate red, green, and blue units in a single case. Simple Eidophors produced black-and-white images. Eidophors were also used in stadiums by touring music groups for live event visual amplification. This opportunity arose as part of the NASA space program, where the technology was deployed in mission control. The Eidophor was a large and cumbersome device and not commonly used until there was a need for good-quality large-screen projection. Areas of the oil unaffected by the electron beam would allow the light to be reflected directly back to the mirror and towards the light source, whereas light passing through deformed areas would be displaced and would pass through the adjacent transparent areas and onwards through the projection system.ДЄs the disk rotated, a doctor blade discharged and smoothed the ripples in the oil, readying it for re-use on another television frame. Light was shone on the disc by a striped mirror consisting of strips of reflective material alternating with transparent non-reflective areas. The disk was covered with a thin film of transparent high-viscosity oil, and through the use of a scanned electron beam, electrostatic charges could be deposited onto the oil, causing its surface to deform.

Eidophors used an optical system somewhat similar to a conventional movie projectorbut substituted a slowly rotating mirrored disk or dish for the film. After six years of work on this project at the ETH, Thiemann moved together with the project to the company Dr. Hugo Thiemann took over this responsibility at the ETH. When Gretener launched his own company Dr.Д®dgar Gretener AG in to develop encyphering equipment for the Swiss army, he stopped working on Eidophor. Its basic technology was the use of electrostatic charges to deform an oil surface. The name Eidophor is derived from the Greek word-roots eido and phor meaning 'image' and 'bearer' carrier.
