The phosphor was patterned Hence the electrons from the guns only fell on one particular aspect with the patterning or another. Employing cyan and magenta phosphors, a reasonable restricted-colour impression may be attained. He also shown the same program making use of monochrome signals to make a 3D impression (named "stereoscopic" in the time). An indication on sixteen August 1944 was the very first example of a functional coloration television process. Work on the Telechrome continued, and plans ended up made to introduce A 3-gun Model for full colour.
The term telly is much more typical in the UK. The slang phrase "the tube" or maybe the "boob tube" derives from the bulky cathode-ray tube applied on most TVs till the appearance of flat-display TVs. Yet another slang term for that Television is "idiot box."[twelve]
