LG Display announces 'highest resolution' smartphone screen

The new 2,560 x 1,440, 538ppi display packs four times the pixels of a 1,280 x 720 display into a package measuring only 5.5-inches.

Did you think that Apple's retina-display screens were the last you'd hear about screen pixel density? Boy, were you wrong!

LG Display has announced today that it has developed the world’s first Quad HD AH-IPS LCD panel for smartphones. The 5.5-inch Quad HD panel has a resolution of 2,560 x 1,440 has four times the pixels of a 1,280 x 720 display, and manages to cram an eye-watering 538 pixels into every square inch.

Compare this to the iPhone 5, which can only manage 328 pixels per inch. However, it is interesting to note that iPhone 5 screens are manufactured jointly by Sharp, Japan Display and LG Display, so higher resolution displays could be on their way to the iPhone too. 

This race to increase pixel density high than retina level – the point at which the human can no longer make out individual pixels – might seem pointless, but it does have the advantage that it allows small HD screens to be produced.

On top of a high pixel density, the screen boasts being the world's thinnest and narrowest panel, being only 1.21mm thick and having a bezel measuring only 1.2mm.

"LG Display, which pioneered the high resolution mobile market with introduction of the world’s first Full HD smartphone panel in 2012, again opens new possibilities with the successful application of QHD technology," said Dr. Byeong-koo Kim, Vice President and Head of LG Display’s IT and Mobile Development Group.

"With this breakthrough, LG Display will continue to raise new standards for mobile resolution and lead the mobile display market."
