We've seen Android run on anything from low-resolution smartwatches to high-PPI phones and tablets, including the new 1920 x 1200-pixel Nexus 7 Google launched earlier this week. To make this possible, the mobile OS supports a number of pixel densities for app content -- from 120PPI (LDPI / Low DPI) to 480PPI (XXHDPI / Extra Extra High DPI). Close examination of the Android 4.3 (Jelly Bean) source code reveals the addition of a 640PPI (XXXHDPI / Extra Extra Extra High DPI) pixel density, which -- according to the comments in the code -- is intended for 4K televisions. Does this mean we'll begin to see Android devices with 640PPI Ultra HD displays? Perhaps, but considering 480PPI is overkill on handsets, this is most likely designed to make image assets and fonts, such as the Google TV UI, readable on 4K screens when viewed from a distance.

Well, it looks like LG's Retina-beating 5-inch display with a 1080p resolution isn't the only screen setting some new pixel density records at the SID conference this week. Japan Display Inc. has now also announced a new 1,280 x 800 display with an amazing pixel density of 651ppi. If you're able to do the math, though, you'll realize that means the display itself measures just 2.3 inches. While it's not clear exactly what sort of devices JDI has in mind for the screen, the company says it's able to produce photographic-level images and text that is perceptibly sharper than even today's highest-resolution displays -- hopefully we'll be able to judge that for ourselves sooner rather than later.
