Oh, you haven’t heard? Having a display with 326 pixels per inch (ppi) was so last year. In 2011, 367ppi reigns supreme. At this week’s SID 2011 conference, Japanese company Toshiba showcased a 4-inch LCD display with a 720 x 1280 pixel resolution and an impressive pixel density of 367ppi. The screen, which will come to market sometime this year, has a contrast ratio of 1000:1 and is capable of displaying video in native 720p. Much has been made of screen pixel-density, thanks in part to Apple coining the term “Retina display” with its launch of the iPhone 4. Apple’s latest smartphone features 326 pixels per inch, making the new Toshiba offering — with 41 extra pixels for every inch — better (or at least denser). What handset will be knighted with the new, ultra-crisp screen? We’re not sure, but we can’t wait to find out.
