Here is the story about IBM's research into CRT flat panels:
Does anyone know why this technology wasn't pursued?
Please read the sources I linked to, not just the brief on the wikipedia article. The sources indicate that the technological obstacles had been addressed late 1990s early 2000s. Unless there is some other technological reasons which haven't been mentioned in this thread.
SO that leaves only the fact that they were never marketed. Which could come down to something as simple as business betting on the wrong horse.
An interesting article, but this still does not provide a logical reason for abandoning crt tech, especially considering that crt flat panels could have been produced more cheaply and would have performed better than LCDs.
Industry has to find a way to get people to buy more stuff. What better way to do that then introducing an entirely new technology. Also, people have a fascination with new tech even when it offers no real advantages over existing tech. Both of these factors probably played into the demise of crt.
