Trinitron is Sony’s brand name for its line of aperture-grille-based CRTs used in television sets and computer displays. Patent protection on the basic Trinitron design ran out in 1996, and it quickly faced a number of competitors at much lower prices. The name Trinitron was derived from trinity, meaning the union of three, and tron from electron tube, after the way that the Trinitron combined the three wega concept manual pdf electron guns of other CRT designs into one.

Color television had been studied, but it was only in the late 1940s that the problem was seriously considered. RCA worked along different lines entirely, using the luminance-chrominance system. Luminance closely matched the black and white signal of existing broadcasts, allowing it to be displayed on existing televisions. Although RCA’s system had enormous benefits, it had not been successfully developed because it was difficult to produce the display tubes.

Black and white TVs used a continuous signal and the tube could be coated with an even deposit of phosphor. RCA eventually solved the problem of displaying the color images with their introduction of the shadow mask. The shadow mask consists of a thin sheet of steel with tiny holes photo etched into it, placed just behind the front surface of the picture tube. Three guns, arranged in a triangle, were all aimed at the holes. The disadvantage of this approach was that for any given amount of gun power, the shadow mask filtered out the majority of the energy. This led to very dim images, requiring much greater electron beam power in order to provide a useful picture.

In spite of this early start, only a few years after regularly scheduled television broadcasting had begun, consumer uptake of color televisions was very slow to start. The dim images, constant adjustments and high costs had kept them in a niche of their own. Low consumer acceptance led to a lack of color programming, further reducing the demand for the sets in a supply and demand problem. Sony had entered the television market in 1960 with the black and white TV8-301, the first non-projection type all-transistor television. A combination of factors, including its small screen size, limited its sales to niche markets.

Sony engineers had been studying the color market, but the situation in Japan was even worse than the U. Morita arranged a deal with Paramount Pictures, who was paying for Chromatic Labs’ development of the Chromatron, taking over the entire project. In early 1963, Senri Miyaoka was sent to Manhattan to arrange the transfer of the technology to Sony, which would lead to the closing of Chromatic Labs. He was unimpressed with the labs, describing the windowless basement as “squalor”.

Ibuka had bet the company on Chromatron and had already set up a new factory to produce them with the hopes that the production problems would be ironed out and the line would become profitable. The Sony Trinitron logo used from 1992 to the 2000s. In the autumn of 1966, Ibuka finally gave in, and announced he would personally lead a search for a replacement for Chromatron. Susumu Yoshida was sent to the U. Ibuka was not willing to give up entirely, and had his 30 engineers explore a wide variety of approaches to see if they could come up with their own design.

During development, Sony engineer Akio Ohgoshi introduced another modification. GE’s system improved on the RCA shadow mask by replacing the small round holes with slightly larger rectangles. Since the guns were in-line, their electrons would land onto three rectangular patches instead of three smaller spots, about doubling the lit area. Ohgoshi proposed removing the mask entirely and replacing it with a series of vertical slots instead, lighting the entire screen.
