What are the advantages of the trinitron picture tube?

Answer 1

For each pixel position a Sony Trinitron picture tube uses a group of 3 very thin red, green and blue vertical lines of phosphorescent material. If you look closely at a Trinitron screen you will see hundreds of red, green and blue vertical stripes, very closely packed together, going across the whole width of the screen. Non-Trinitron tubes use triplets of tiny red, green and blue phosphorescent dots instead of lines. When it was first invented back in the early 1970s Sony claimed that the Trinitron system gives a sharper picture because, on the production lines in the factories, putting in place the phosphor lines could be controlled much more accurately than having to position millions of separate dots. Over the past 30 years systems for manufacturing picture tubes using triplets of tiny red, green and blue dots have improved so much that the Trinitron design may no longer have as much superiority as was originally claimed for it, but it is still an excellent system.
