Title: Thermoelectric display cell for recording images line by line

Abstract: A device for displaying a television video signal comprising a liquid-crystal layer inserted between two substrates. A plurality of heating lines deposited onto one substrate heats successively the layer up to an erasure temperature. A plurality of columns apply to the liquid crystal layer during the cooling of each line, samples of a video signal representing the image to be displayed. The lines of the image are thus recorded one after the other and all the dots of one line are simultaneously recorded thus allowing the layer to be heated and cooled along one line during the duration of one TV line scan.
