LG Display Co Ltd. (NYSE:LPL) revealed today that they have made the world?s first QHD (2566 x 1440) display for smartphones. This Quad HD AH/IPS LCD panel measures 5.5 inches which gives an astonishing 538 pixels per inch.

Just to provide you with some perspective, Samsung?s flagship Galaxy S4 has a pixel density of 441ppi, and HTC?s One has 468ppi. The panel has four times more pixels than a common smartphone 720p screen. Many may wonder if 538ppi is truly necessary ? or even noticeable at this level, if for nothing else but for pure technical advancement? Be that as it may, LG Display continues on to confirm their status of one of the leading innovators when it comes to display technologies ? as this ludicrous resolution and pixel density is only a part of the story involved in its making. The company recently announced the world?s thinnest FullHD LCD panel for smartphones, but this new screen easily outclasses it, being only 1.21mm thick and having only 1.2mm on the bezel side ? setting a new record.

LG's record-breaking panel

"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."

Thanks to the usage of the Low Temperature Poly-Silicon (LTPS) substrate, this panel features 430 nits of brightness with improved transmittance. Color reproduction is said to be more delicate, and contrast enhanced when compared to the current displays.

Additionally, LG mobile communications exec confirmed that flexible display panels are coming soon ? and first products it are expected to arrive in 2014. At least one of those products could actually be the rumored smartwatch, but that?s a whole different story.
