No, Slacker, they aren't especially worse. Sharp does have the only 10G fab, which is why it makes the 70" TVs for everyone who is selling them. It gets a clean, near-perfect utilization of the 10G sheets and a 2 x 3 cut of 70" panels.
I was just generally pointing out that 77" wasn't a good size in any particular way. It was perhaps chosen because LG could process it in their vapor-depo units or because that was a backplane size they could make, but it's not a "real size" in any particular sense and doesn't seem to be especially good for marketing either (it's not a magic number of any sort).
This is a huge problem with 8G generally. It simply doesn't scale past 55" very well. You've seen a good deal of 60s and 65s, so it's worth understanding that they can be made, they just can't be made particularly efficiently is all.
One serious hope for OLED is that roll-to-roll is going to become a real way to make displays instead of the "sheets of glass method". The Sony/Panasonic production process could well lead to that being real since it deposits the OLED using a printing technique. With roll-to-roll, you can order substrate in any width you intend to produce and efficiently produce any size without waste. But this presumes that you can print fast enough that you actually gain speed on what was the slowest step before. So there is much work to be done there. Still, it would be a big win if it happens.
