Smartphone display wars go to ludicrous speed: 2560×1440 in 5.5 inches

LG logoTired of the absolutely terrible 468 pixels per inch (PPI) of the HTC One, or Apple's hideous retina display with its measly 326 PPI? Then LG has some great news, in the form of a 5.5-inch, 2560×1440, "Quad HD" IPS panel. That's a resolution you'd normally find on a screen measuring 27" or 30" diagonally, and it yields a whopping 538 PPI.

To put that into perspective, the human-perceptible limit at a 12-inch distance is only around 300 PPI. That's not to say anything above 300 is a waste; hold the phone closer and you'll need a higher PPI to see an unpixelated image. 538 PPI, however, is just insane.

Smartphone display wars go to ludicrous speed: 2560×1440 in 5.5 inches

In addition to packing the tiniest pixels ever made, LG is claiming the new IPS panel is "the world's slimmest and narrowest." It measures just 1.21 mm thick, with a 1.2 mm bezel. The ludicrous resolution is paired with a much more pedestrian brightness rating of 430 nits (compared to, say, an HTC One's rating of 500 nits).

If this kind of crazy resolution one-upmanship seems like a pointless waste of battery power, then hold onto your hats: Android 4.3 includes support for 4K resolution. Google initially intended this capability to be used for 4K television support, but it seems almost inevitable at this point that we'll see smartphones resolutions edging up into that space.
