Sony has some incredible engineers, and I wouldn't be completely surprised if they improved on that experiment, and did something with it. Interesting tidbit about the Sony Trinitron tube, which was probably the best CRT over all for 40 years: Philco demonstrated a one-gun color CRT basically the same as a Trinitron in 1950, but nobody in the USA could figure out how to perfect it. Sony bought the rights to it in the mid 1960s, and introduced the Trinitron in '67 ('68 for the USA). They also perfected the video cassette (first with the uMatic and then Betamax), when the USA (Ampex and Bell Laboratories) was unable to make a video tape recorder much smaller than a Toyota. If it can be done, Sony will do it before others can figure it out...
