Ars tackled one specific feature of Apple’s tablet this week: The Display and specifically would it be OLED-based or traditional LCD? Their conclusion? Not OLED.
Based on the assumption that it would be a 10-inch variety (and that’s been reported often), they talked to part suppliers who noted that there were only two producers of AMOLEDs that size. Samsung, the biggest producer and also an Apple supplier, can only produce about 150,000/month. And those are apparently more than accounted for. Another Apple partner, LG, makes about one fifth of what Samsung can produce. Neither of these companies, nor both of them together could possibly supply the amount of displays that Apple would need.
Therefore, they conclude that the tablet wil be a traditional LCD.
That’s not to say the iPhone 4G won’t have OLED however.
