Chromatron showed great promise but have never seen one.
Could be because research funding was sponsored by "Paramount Pictures" Yeah, Paramount would really want this to succeed & empty more theater seats to TV. Like when General Motors started "magnanimously" buying Electric Trolley routes and guess what happened next. |

I have read that Sony secured a license in 1962 and produced about 13,000 17 inch Chromatron sets, using vacuum tubes in 1964... It was a disaster! (would love to have one of those in my collection, however)
Later, much the same target/mask structure plus the inline gun structure from GE plus an innovative focus structure yielded the Trinitron, so I guess that the Chromatron design was not really a dead end. jr |

OK youngsters, lets review history a bit. At the time the ABC Network was owned by Paramount Theaters and was in the process of switching to color and managed to get more shows on the air in Color than CBS did. Officially Paramount Theaters and Paramount Pictures were separate, but unofficially both were intertwined. Funding from Paramount brought ABC from a distant third place, to barking at CBS's heels in ratings, but not in number of stations. Jas. |

Says it nearly sent Sony broke!
"The production problems were never solved, and led to increasing tension between Ibuka and Morita. In November 1966 Kazuo Iwama told Susumu Yoshida that the company was close to ruin..." http://en.wikipedia.org/wiki/Chromat...ny.27s_attempt |

Hollywood had a hand in writing a later chapter in this saga as well. Sony received an Academy Award for the Trinitron some years later. It's kind of ironic, since Hollywood had lined its pockets with the hard-earned money of people in the radio/television industry for decades. It was both a slap in the face and a push down the road to oblivion for a proud and vital segment of our economy.

I found this Picture of Ibuka and his 1973 Emmy... did Sony get an Oscar as well?

No, my mistake. it was an Emmy. Read the info at their website:
http://www.sony.net/SonyInfo/Corpora...tory/2-14.html Quite an honor nonetheless, for hard work and dedication to an ideal. It's a shame few know that RCA had also won the Emmy for the three-gun CRT (1956) and a videotape cartridge design (1974). Remember, it was Americans who prepared the media onslaught, along with government apathy, that delivered the one-two punch ending thousands of manufacturing jobs we still haven't replaced today. Even fewer people know of this amazing (for its time) device: http://www.rcaselectron.com/ |

A few words about the Chromatron can be found in the biography of E.O. Lawrence
entitled 'An American Genius'. Lawrence (1900-1958) was a talented applied physicist, and he was involved with a number of other people in the development of that picture tube. His early death, along with electromagnetic compatibility problems, may have hampered the commercial succes of the Chromatron. Sorry I don't remember the author's name, I believe the book was published in 1968. |

Patent very complex, intricate. The work of a genius in 1951
http://www.google.com/patents?id=7n9fAAAAEBAJ But almost impossible to implement.. But one aspect did work very well - the hype http://www.bretl.com/tvarticles/rtve1264/rtve1264.pdf This was a great journalism - Must've got Sony excited ! |

Just another idea that the Japanese took and ran with Just like the early consumer video recorder developed by Ampex who went bK and sold the rights to JVC.

I used to work for a guy who was sent to Chromatic Labs in the 50's by his employer (Thomas Electronics) to learn to build the Chromatron tube. His comment to me was, "I was there two #$@%!%$ weeks and didn't see one $#@%$## good tube."
