Apple leads the pack when its comes to display ppi (pixel per inch) on smartphones. The iPhone 4’s Retina display with 326 ppi stole the show last year and though a lot of manufacturers have phones with good displays out there, we are yet to see anything beating the Retina displays resolution. But now as the iPhone 4 gets a year old, the competition is really heating up. With Samsung readying a Retina display for tablets, Toshiba has just also unveiled a 4″ display, capable of playing back 720p movies (720×1280) and a pixel density of 367ppi.
This thing sure sports a resolution higher than a few tablets that we have seen in the market. The Hitachi display doing similar resolution on a 4.5″ screen now looks old. Engadget seemed impressed with the output and we wonder what would eventually run this display? An Appy surprise or the Androids?
