More on iPad 3 coming this spring, difficulty in producing Retina Displays

The Wall Street Journal tells us that -- surprise, surprise -- Apple is working on a Retina Display iPad 3 for this fall!

The Cupertino, Calif., company has ordered key components such as display panels and chips for a new iPad it is aiming to launch in early 2012, said the people.

The next generation iPad is expected to feature a high resolution display - 2048 by 1536 compared with 1024 by 768 in the iPad 2 - and Apple's suppliers have already shipped small quantities of components for the sampling of the iPad 3. Suppliers said Apple has placed orders for a 9.7-inch screen device.

Digitimes' sources caution, however, that Retina Displays of that size are proving tricky to produce.

The sources noted that the iPad 3's resolution requirement of 2,048x1,536 pixels is also a challenge even for iPad panel regular suppliers such as LG Display (LGD) and Samsung Electronics. Apart from the two Korea makers, Japan's Sharp has als been selected to supply panels for the iPad 3, the sources said.

TiPb previously reported that, while Apple had considered moving iPad 3 up to a fall 2012, problems with Retina Display component costs and yield rates, Apple had moved iPad 3 back to it's traditional spring launch window.

If the displays continue to be so challenging to produce, does Apple stick with 1024x768 for generation 3, or do they move the launch further out into summer 2012?
