Here’s an interesting rumor coming from Japanese blog Macotakara [Google Translation] while you’re still trying to wrap your head around the news that Steve Jobs has taken another medical leave of absence. According to “sources of information” close to Macotakara, Apple is considering a glasses-free 3D screen technology for a future iPod touch, with an approach similar to what Nintendo is doing with the 3DS – a gaming handheld capable of projecting 3D images out of the screen without the need of wearing glasses.

In the past, Apple was granted several 3D-related patents and other third-party manufacturers played around with the idea of bringing 3D to iOS devices. Macotakara, however, reports that Apple is willing to integrate 3D into the iPod touch’s screen without any external peripheral or accessory. The 3D panel should be developed by Sharp.

According to a source of a company which provides LCD to Apple, they seems to begin preparing to manufacture small glasses-free 3D LCD panel for iPod touch.

This 3D LCD panel looks similar to Sharp, corp’s LCD which is capable for displaying 3D image without glasses on vertical and horizontal position.

While this is all based on pure speculation, it’s interesting to think that Apple might fight Nintendo at its own game with the iPod touch, which has been touted has world’s most popular gaming device several times in the past. Apple is clearly investing on the appeal of the iPod touch as an entry-level iOS device that’s perfect for portable games, and a mobile 3D screen would be another technological breakthrough for the company.
