[QUOTE=NewVista;3168351]The Chromatron looked Super!

"Funny how Sony couldn't make it work like Dr Lawrence could in the early 50s!"

I totally disagree with that comment. The Trinitron is an improved Chromatron. The Trinitron was the most successful television design in the world with a 40 year production run, until the flat panels killed the Trinitron.

After Sony acquired the patents and development rights from Paramount Pictures, Sony filed over 100 patents with their own ideas and inventions that made the Chromatron viable and renamed their invention "Trinitron". There were many other companies that worked on the Chromatron, but Sony was the first to make it work.

Doctor Lawrence through Chromatic Television Labratory, demonstrated both one and three gun Chromatron's. All of the original Chromatron principals are used in the Trinitron:

One gun, tri-color vertical phosphor stripes, high brightness by inventing the aperture grill with unbroken vertical slits allowing a greater percentage of the electron energy to reach the phosphors.

Then Sony took the Chromatron design further and improved on it with superior focusing and depth of field.

Finally, Sony actually markeded PDF Chromatrons in Japan and the U.S.

The storys about the struggles Sony had with the single cathode PDF design are true, but they did not give up and as a result the Trinitron was born, son of Chromatron.
