http://www.blogcdn.com/www.engadget.com/media/2013/07/dsc06445-1374687225_620x340.jpgWe've seen Android run on anything from low-resolution smartwatches (http://www.engadget.com/2012/02/07/inpulse-and-wimm-one-the-tale-of-two-smartwatches-video/) to high-PPIphones (http://www.engadget.com/2013/07/05/htc-one-google-play-edition-review/) and tablets (http://www.engadget.com/2012/11/02/nexus-10-review/), including the new 1920 x 1200-pixel Nexus 7 (http://www.engadget.com/2013/07/24/nexus-7-2013-hands-on/) Google launchedearlier this week (http://www.engadget.com/2013/07/24/google-breakfast-liveblog/). 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 (http://www.engadget.com/2013/07/24/android-4-3-jelly-bean-official/) (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 (http://www.engadget.com/tag/4K/)televisions. Does this mean we'll begin to see Android devices with 640PPI Ultra HD (http://www.engadget.com/tag/UltraHD/)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 (http://www.engadget.com/tag/GoogleTV/) UI, readable on 4K screens when viewed from a distance.
