Apple’s component suppliers say Retina Display might not arrive for iPad devices in 2011

As nifty as Apple’s Retina Display is, it might be hard to put in all of its devices.

Per DigiTimes, component makers for Apple’s iPad claim that the company has released its roadmap for higher-resolution touchscreen tablets, but the project is still at the “initial planning stage” and an upgraded iPad is unlikely to come later this year, according to a new report.

Insiders suggest that Apple could choose AMOLED technology or a high-resolution standard as part of its plan to upgrade the image quality on the iPad.

“Sources from touch panel makers pointed out that Apple recently released its latest tablet PC plan and is asking the panel makers to provide products that are capable to support higher image quality than the current iPad 2,” the report read.

“Apple may even choose AMOLED panel or panel that support Full HD standard to accomplish the plan. However, since the project is still at the initial planning stage, the actual products are unlikely to appear in 2011.”

Sources also cautioned that Apple may hold off on moving to AMOLED because rival Samsung mostly controls the technology. “If Apple is adopting AMOLED panel into its device, Apple would be facing a great risk having the key technologies being held by its competitors,” the report noted.

Upstream component makers pointed out that, given the production ramp up for the iPad 2, launching an iPad 3 this year would “simply bite off share” from the iPad 2.

Further quashing rumors of an iPad 3 in 2011, sources said that they have yet to receive “any notice for next generation iPad products” and do not believe the iPad 2 is a “transitional product.”

Even before the iPad 2 had been announced, rumors emerged earlier this year that Apple would release an iPad 3 in 2011.

Those rumors appeared to have been put to rest after Apple CEO Steve Jobs declared 2011 “the year of iPad 2.” However, intermittent reports since then have continued to suggest that Apple could release an iPad upgrade in 2011.

According to analyst Ming-Chi Kuo with Concorde Securities, Apple faced supply constraints and cost limitations that prevented the iPad maker from adding an improved display to the iPad 2. Kuo has suggested that a Retina display is still in the pipeline, and could make its way into the iPad 3 in early 2012.
