They negotiated a license to the technology more or less on the spot. At a 1961 trade show sponsored by the Institute of Radio Engineers, one of IEEE’s predecessor societies, Sony executives saw a Chromatic set in operation. Sony was determined to never be a copycat (or pay royalties). This technology, which was called a Chromatron, also created a brighter picture, because it had no shadow mask, though Chromatic could not get the technology to work consistently. Lawrence of the University of California, Berkeley, it tried to use a single electron gun and replace the shadow mask with a grate of charged vertical wires. Basing its approach on an idea of renowned physicist Ernest O. outfit called Chromatic Television Laboratories was on yet a different tack. General Electric rearranged the guns into a row (instead of a triangle) and was getting good results. For example, RCA, the world’s leading manufacturer of television sets at the time, began using rare earths that would phosphoresce more brightly. There were multiple angles to work to improve color TV. #Challenge serial on sony tv tv#Color TV screens weren’t as bright as they could be, in part because of the wastage of all those charged particles. Furthermore, the shadow masks blocked a lot of electrons that otherwise could have been used to make each RGB trio phosphoresce more intensely. #Challenge serial on sony tv professional#The electron guns had to be in perfect alignment, however, and they got out of alignment often enough that they occasionally needed professional adjustment. The holes in the mask would allow through only those electrons from each gun traveling the path to the gun’s designated dot in each triad. The way TV manufacturers dealt with that was by incorporating the shadow mask. Aiming each gun at only one dot in each trio would work if the guns emitted electrons in a tight beam. This “refresh rate” was typically 60 frames or more per second. To make moving images, the screen had to be lit, or “painted,” many times per second. Electrons from the guns scanned back and forth many times per second, lighting the appropriate dots to make a color image on the screen. The color that each triplet displayed could be selected by firing the guns to light up the right combination of dots to create the desired color. In theory, any color visible to the human eye can be created with different combinations of red, green and blue (RGB) light.Įach of the three electron guns was aimed at only one phosphor dot in each of the RGB triplets. In each trio was three dots, chemically created so that one emitted red light, one green, and one blue. When electrons hit the dots, they emitted light. The screen was patterned with millions of tiny phosphorescent dots, arranged in trios. The main elements in original color TV sets included, from the back of the cabinet to the front: three electron emitters, or “guns,” arranged in a triangle these pointed at a barrier, called a shadow mask, that was perforated with holes beyond that was the screen with its phosphors. Like so many innovations, it evolved out of multiple failures.Ĭolor in TVs was achieved by exciting phosphor dots on the internal side of TV screens. The Trinitron, unveiled by Sony in 1968, was the first major technological advance in color television sets since they were first commercialized in the early 1950s.
