Labels:text | cartoon OCR: TELEVISION SET T `HE SIGNALS sent out by a television station are picked up by an antenna and used to control electron beams inside your television set. The screen glows where a beam strikes it, and a picture builds up. As many pictures are built up each second, the image appears to move. Color screens have red, green, ANTENNA and blue patches, each made to glow by one of three electron beams.
