iPad 3 is rumored to come out in March 2012. And the wish list seems to be growing longer day by day. If we talk about the latest spin on iPad 3 display, internet is replete with the news that new generation tablet PC will support high resolution retina display by making use of the IPS technology. Many expect iPad 3 to feature improved backlighting which needs dual LED support, in order to comply with the enhanced resolution. And here comes the latest, will iPad 3 characterize 3D display as communicated by its prototype? And more on why 3D screen can’t be a reality.

Business Insider first reported this week that iPad prototypes prepared early this month showed 3D screen. From an inside source friends with an Apple employee this information got leaked. They said Apple was experimenting with some 3D screens to see if it works out.

“The iPad 3 was often called iPad 3D in early prototypes.”

However, what is different is that one may not require 3D glasses to look at this screen. Now their same source conveyed that Apple seems to have ditched the 3D concept as they dint want it to be a gimmick. Also that 3D will come to iPad when it is ‘required’. For now, Disney is busy converting its catalogue into 3D to be ready for that final call.

It is rumored Apple had filed for a 3D patent early this fall. A display manufacturer CPT revealed a prototype to the world that might pave the way for 3D iPad 3. Dylan from Disney says that iPad 3 if 3D enabled will allow a user to interact with holographic images or project their hands onto a screen to manipulate virtual objects. News on improved screen resolutions for Apple’s devices is one reason to expect the tablet can sustain 3D display. As only plenty of resolution will allow 3D to step in.

However, it is a bit difficult to believe this theory. As this isn’t for the first time that Apple has filed for a patent, not so ready to be incorporated yet. Secondly, the techie might be working on 3D gestures which also it has patented for use in iOS devices, though it works more for an Apple TV type of device. Thirdly, as 9To5Mac reports, there was a story about an App that used iPad 2 camera to find out where your head was and then it made 3D objects appear on the screen.

The theoretical notion is cool but practical realization can be tough.
