iPad 3 Expected to Ship with Sharp IGZO Display
As the launch of the new iPad 3 is coming shortly, so do the rumors increase about its specifications. The new iPad 3 is expected to have LCD screen measuring 9.7 inches with a pixel display resolution of 2048 x 1536. This resolution is higher than the 1024 x 768 of the iPad 2, and therefore offers sharper images.
For some time, it had been speculated that the screen panels would be created by Sharp using their new IGZO (Indium Gallium Zinc Oxide) technology. IGZO offers a high resolution of up to 330 dots per inch without the need for LED backlight. Some, however, have already discounted the possibility claiming that the next-generation iPad will sport LGD or LG Display.
In any case, Sharp is manufacturing large quantities of the IGZO displays at the moment and none of these are available commercially. This fuels the possibility that Apple is still interested in using the product for the iPad 3.
IGZO displays are preferable over the traditional screens made of amorphous silicon because IGZO has a higher electron mobility. This enables more light to penetrate the back of the display, reducing the need for LED backlights, and thus, the production cost.
