As early as 1940, Baird had started Focus on a fully electronic procedure he termed Telechrome. Early Telechrome products utilized two electron guns aimed at possibly side of a phosphor plate. The phosphor was patterned Therefore the electrons from the guns only fell on one facet from the patterning or the opposite. Using cyan and magenta phosphors, a reasonable limited-colour impression might be attained. He also demonstrated the same process applying monochrome signals to produce a 3D impression (identified as "stereoscopic" at the time).
