Technicolor in TV

The colour tv invention in America

Until the middle of 20th century, we could only watch  black and white tv. It wasn´t until  1940 that Guillermo González Camarena, being just 23 years old, invented a new application, which using the "Trichromatic" system, made  colour tv possible .

The method used was called  "field sequential" system. With the primary colors: Red, blue and green and a motor-driven disc rotating  inside behind the camera lens. The resulting film is monochromatic (black and white) but if it is replayed fast enough, then, you can see a complete full-color image. As you realized, just with these three colors you can get a full-color picture.

Who was Guillermo González?

Guillermo González  was born in Guadalajara, Mexico, on the 17th February, 1917. At the age of 13, he began studying mechanical-electric engineering but he didn't finish this course because he began working at the National Radio Station. During this time he did many experiments on  that field. Finally, in 1930 he finished his studies and he was graduated as a mecanich-electric engenieer. He died in 1965 when he came back from work, he suffered a traffic accident. He was a multi-faceted man: he was an inventor, constructor, and a successful and famous engineer.

By 1939 he had already developed his Trichromatic system and by 1949 he had obtained the world's first patent for color television. By 1950 he had also invented the first remote control for television.
