New 4.5 inch LCD is more "Retina" than Apple's

And ad for Apple's Retina display

Move over Retina display, Hitachi has one-upped you with an amazing new display, capable of up to 1280 x 720 resolution on a mere 4.5 inch screen. This makes for a PPI of 329, giving it a slight edge over the 326 PPI of Apple's Retina display. Add to that the fact that Hitachi's display is larger, and I think we have a winner. Look forward to the first batch of phones using it sometime in 2012.
