The phosphor was patterned so the electrons from the guns only fell on 1 side from the patterning or the other. Employing cyan and magenta phosphors, a reasonable restricted-color picture might be received. He also shown the same procedure employing monochrome signals to create a 3D image (called "stereoscopic" with the time). An illustration on 16 August 1944 was the main example of a realistic color television method.

This was transmitted by AM radio waves into a receiver unit, exactly where the video signal was placed on a neon light guiding a second Nipkow disk rotating synchronized with the main. The brightness on the neon lamp was assorted in proportion for the brightness of each spot on the image. As Just about every gap while in the disk passed by, just one scan line of the graphic was reproduced.
