The iPhone 4's 960 x 640 IPS "Retina" display is one of the best in the mobile world thanks to its high resolution, pixel density, and clarity. However, it may soon lose its crown as Hitachi has unveiled a 4.5-inch display that boasts an impressive 720p resolution and glasses-free 3D.
This display should look amazing, as the 1280 x 720 resolution gives the display a DPI (dots per inch) rating of about 326, which matches that of the iPhone 4. Of course, this display is also an inch bigger than the iPhone's, which should make it even more of a joy to look at. Not only that, but it also uses lenticular technology for 3D instead of the parallax barrier on devices like the HTC EVO 3D and LG Optimus 3D. This allows for greater brightness in 3D mode, along with "better image quality."
We still don't know when this display will be incorporated into devices, but it does have some surprising links to other rumors. The Nexus Prime is rumored to have a 720p display, and the Samsung Galaxy 3D will need a large 3D display as well. Could this be the display the devices will use? We have no way of knowing now, but I can't wait to see this screen built into a new device that I can buy.[TechCrunch]
