Only last month, LG Display gave us a glimpse of a possible future filled with super-thin smartphones by unveiling the "world's thinnest" Full HD display panel. Now the company has pulled back the curtain on an even slimmer LTPS-based LCD display called the Quad HD that also stakes a claim for the title of highest resolution mobile display produced so far.

The Quad HD AH-IPS panel is so named because it packs in four times more pixels than 720p displays. That translates to a 5.5-inch display panel with a 2560 x 1440 resolution at 538 pixels per inch (ppi). At 430-nit, it's not as bright as last month's 5.2-inch panel from LG Display, but it is a good deal slimmer at 1.21 mm (with a bezel of just 1.2 mm).

A quick comparison with Gizmag favorites already on the market shows the new panel to be a clear winner. The iPhone 5 has a resolution of 1136 x 640 at 326 ppi, Samsung's Galaxy S4 comes in much higher at 1920 x 1080/441 ppi, and the HTC One beats both with a stunning 1920 x 1080 resolution at 468 ppi.

LG Display says that currently-available smartphone screens can't touch its new panel for color reproduction or contrast ratio either, which should make mobile movie viewing more of a pleasure, as well as offering crisper text and more vibrant images.

Unfortunately, there's currently no official word on how long we'll have to wait before this technology makes its way to the consumer space.
