With the Retina Display Apple changed the rules of mobile screens. Since, we've seen bigger, brighter and shinier phones faces, but none higher resolution than Apple's 326ppi iPhone 4 glass. Now Toshiba has beaten it with a new 4in, 720p, 367ppi display that has a staggering 1,500:1 contrast ratio and whole-train-carriage-entertaining 176 degree viewing angle. Rumours of the next generation iPhone suggest all manner of details, yet size apart few have mentioned the screen. Since Apple shares a production factory with Toshiba, it's time for that to change. Let’s hope Toshiba likes to share.
