LG today claimed to debut an industry first: a 5.5-inch quad high-definition, in-plane switching LCD screen for smartphones. The quad HD resolution display includes 2560 x 1440 pixels, which creates a pixel density of 538 pixels per inch. The panel measures 1.21mm thick and has a 1.2mm bezel. LG claims it is the world's thinnest and slimmest display panel, slimmer even than the one used in the G2. The display also uses a Low Temperature Poly-Silicon (LTPS) substrate to allow for a brightness of 430nit. Quad HD screens are the next logical step after 1080p HD. LG says the high resolution will let smartphones display full-sized web pages with sharp text and no distortion. LG did not say when the new panel might be made available to device makers.

Limitations of sight

I think displays are hitting a point where very soon, the display resolution will be way beyond the capabilities of human vision. After this, the next logical step would be to again divide each pixel into 4, and that would definitely be way beyond what the eye can see (if we're not already there with this technology!)
We're pretty much there already. I can barely see the difference in pixel density of my Nexus 2012 and 2013. Even though it has a higher resolution display and higher pixel density, I'm hard pressed to see a night and day difference. At normal viewing...
