On Wednesday morning, LG Display announced the first Quad HD AH-IPS LCD display for smartphones. The Korean based company, which brought the first FHD panel for smartphones in 2012, says that the new display offers a 5.5 inch screen with resolution of 1440 x 2560. That would work out to a pixel density of 538ppi and would be 70ppi higher than the industry leading 468ppi experienced by HTC One users.
According to LG Display, the new screen would contain 4 times the pixels used on an HD screen (720 x 1280) and would result in a clearer picture. Colors will be more vivid and viewers will notice an improvement in contrast. The panel will bring "Blu-ray equivalent video" to the smartphone screen. In addition, the screen will allow web browser on a smartphone to view full PC-version web pages without distortion to the image. FHD panels allow viewers to see 3/4 of a PC-version web page. Speaking of no distortion, zooming in on an image will bring distortion-free, sharp text to the smartphone screen.
The new LG Quad HD panel is the slimmest and narrowest panel in the world. It will be only 1.21mm thin with a 1.2mm bezel measured in LCD modules (LCM). It is 12% thinner than LG Display's 5.2 inch FHD screen released last month. The screen is also bright with a reading of 430 nit.
"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. With this breakthrough, LG Display will continue to raise new standards for mobile resolution and lead the mobile display market."-Dr. Byeong-koo Kim, Vice President, LG Display’s IT and Mobile Development Group
LG didn't announce when the panels might be ready to ship. At this point in time, they offer the highest resolution and pixel density available for a smartphone screen.

Seoul, Korea (August 21, 2013) – LG Display [NYSE: LPL, KRX: 034220], a leading innovator of display technologies, announced today that it has developed the world’s first Quad HD AH-IPS LCD panel for smartphones. At 2560X1440 with 538ppi, the new 5.5-inch Quad HD panel is the highest resolution and ppi (pixel per inch) mobile panel to date, and provides a glimpse at what’s next after current Full HD smartphone panels, critical given the growing trend towards larger displays.
“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.”
LG Display’s Quad HD panel for smartphones realizes clearer images with 4 times more pixels than HD at 1,280X720, thereby reproducing more delicate colors as well as improving contrast and vividness when compared to current mobile displays. This advancement will enable consumers to fully enjoy more life-like and crisp images, and even Blu-ray equivalent video, on their smartphones. The panel also features the highest ppi among current mobile device displays.
In addition, the new Quad HD panel will enable users to enjoy a full view of PC-version web pages at a single glance without image distortion; a contrast to current Full HD displays which only realize 3/4th of a full screen. Also, even when enlarging the screen, users will be able to enjoy undistorted and sharper text.
Only 1.21mm thin with a 1.2mm bezel measured in LCD modules (LCM), LG Display’s new Quad HD panel is both the world’s slimmest and narrowest panel, with 12% reduced thickness compared to the company’s 5.2-inch Full HD panel released last month. Based on Low Temperature Poly-Silicon (LTPS) substrate, the panel also realizes superior brightness of 430nit with improved transmittance and larger aperture opening size.
LTPS-based smartphone displays are expected to record 765 million units in shipments next year according to research firm DisplaySearch, as displays with larger screens, higher resolution, and less power consumption prove key to competitiveness in the premium model segment.
