Yes, but TFTs didn't start at only 8" meant as a computer display.
Um, are you a young'un? ;)
Your statement is factually incorrect. See: Mac Powerbook 170 9.8"
640x400 and and Powerbook 180c 8.4" 640x480. Egregiously expensive,
power hungry, and notorious for pixel failures.
This was at the start of TFT's. At the time, nobody dreamed that they
would eventually replace CRT's.
Has to do with how OLEDs are produced. Producing a *small* OLED panel is easy,
and those go at below 60 bucks in RGB. But as soon as you increase panel
size, you have to make bigger light emitting cells.
You can also make more of the same size. Just like TFT's. A single
pixel error on a TFT TV doesn't drop an area a quarter inch square. It
only wipes a single element of the cluster.
You don't have that
problem with TFT since you only have to make a larger backlight area and
cover that with larger LC fields. Not too hard.
Yeah, tell that to the poor engineers who had to slog through this "not
too hard" problem and the companies who have to invest in completely new
fabs at each new generation. There is a reason that TFT prices are
exponential with number of pixels.
Cell display != desktop computer display. I had LCDs in pocket calcs 20 years
ago, that would be saying like TFTs weren't vaporware 20 years ago because
the calc LCDs existed.
20 years ago was only 1987. TFTs weren't vaporware. They were just
egregiously expensive. 4 years later they were in a portable computer
and merely expensive.
In addition, not all of the expense in TFTs was TFT technology. TFTs
needed digital semiconductors working at quite a lot faster speeds that
a CRT system. Graphics chips were a hard problem in 1991. OLED does
not have this problem since TFT has already paved that path.
Uh.. your fav bunch of IT newsticker, tech newspapers..?
Uh ... do you really think I would have asked if the rags I read said
anything concrete? All of my engineering rags indicate that the
emission stuff is still stuck in the lab.
