New iPad, Plan B?

According to an article on C-Net, it appears that Apple had big plans for the new iPad that was foiled by the unavailability of an IGZO display from Sharp. This new screen would have allowed for a much thinner iPad and wouldn't have required the 70% increase in battery size of the iPad to maintain the 10 hour rating.

IGZO stands for Indium gallium zinc oxide and it replaces amorphous silicon for the active layer of an LCD screen. IGZO provides forty times higher electron mobility than amorphous silicon, it allows either smaller pixels (for screen resolutions higher than HDTV) or much higher reaction speed for a screen.

"The plan was to use this new technology called IGZO from Sharp -- a lot higher electron mobility that allows them to make the transistors a lot smaller and the circuit elements a lot smaller,"

"There's no question that the iPad 3 is Plan B. They pushed amorphous silicon to a higher [pixels per inch] than anybody else. But the light throughput is not good. So it has roughly twice as many LEDs, and they had to get a 70 percent larger battery,"

"The idea was that IGZO would enable a brighter display and you could use less LEDs and you wouldn't need as big a battery compared to amorphous silicon,"

Maybe the Sharp IGZO display will be used in the iTV from Apple!
