I am not saying OLED won't catch on. No doubt OLED is the likely future of the common display, but we aren't talking about them replacing LCD by the end of the year. Maybe in 2 years time they will be more common and at a lower cost. The fact that they have been saying CRT quality on a panel thinner than an LCD while also using less energy is certainly impressive, but things like this are also not so simple. As the big manufacturers start to put more money towards it, the technology will progress much faster and they are just starting to do that.
I already read the article about Samsung also showing a 55" display and that article specifically said "not ready for the mass market", but it WILL be shown at CES. As your linked article said, OLED has been shown at CES for years...
Also linked in your article is the "clearing the roadblocks for OLED" (I didn't read the whole thing). The number one factor being that they are JUST NOW able to produce displays capable of mass production. The second, and this one is definitely a big point, is that there are no fabs setup to do this mass production yet abd that is the biggest way to bring cost down(no plant, no product). Someone has to build the equipment to go in those fabs to do said production. Large scale fabs take 1-2 years to get up and running, and the equipment they are producing the current ones on are likely still prototype machines.
A plus will hopefully be that the equipment to make the OLEDs will be less expensive than current LCD gear. Any idea how big of a piece of equipment it takes to "inkjet" a 55" display is? we aren't talking about something that sits on your desk. Let's just say I could park a few cars inside the footprint of one. And the LCD process equipment is even larger than that. One machine for LCD for the current average size of 46-55" panel is about the size of an average home.
I bought stock in an OLED start up almost 10yrs ago. I never got a return on that money, but maybe if I had left it in, it might be worth something now. I've also been working, directly for 5 years previous and indirectly for the last 5 years, in the flat panel display industry making all that equipment. Granted, I haven't followed OLED so closely of late.
