Apple makes a big fuss when discussing the razor sharp images of the iPhone's Retina display, but now there's a new resolution champ that tops Apple's offering by a solid third.
Sharp's new 5-inch screen is the first display to offer 1920x1080 "full HD" video resolution in a size small enough to use in a smartphone. Compare that to the iPhone 5's 1136x640 4-inch display, and it becomes clear that this is a pretty big step. Crunch the numbers, and you'll find that the Sharp screen manages to cram in 443 pixels per inch, compared to the iPhone 5's 326 ppi. The picture above shows the two screens side by side, to give an idea fo the size difference.
Of course, five inches makes for a pretty humongous cellphone, but it's not something we haven't seen before. Samsung's new Galaxy Note 2 is even bigger with its pocket-busting 5.5-inch screen.
To get so many pixels crammed into such a tiny place, Sharp uses something called Continuous Grain Silicon (CG-Silicon) thin film transistor technology, which requires fewer layers to create the image. This means the display can also be thinner, leading ever onward to slimmer smartphones.
Sharp is currently showing the display at CEATEC 2012 in Japan. No word yet on which phone this pocket-sized HDTV screen may eventually show up in.
