Smartphone displays on high-end devices such as the Samsung Galaxy Nexus (4.65";  1280 x 720 resolution; 316 pixels-per-inch), Galaxy Note (5.3"; 800 x 1280 resolution; 285 ppi) and Sony Xperia S (4.3"; 1280 x 720 resolution; 342 ppi) are getting bigger while also adding more pixels. LG has now introduced its new 5" full HD (1080p) LCD panel for smartphones, asserting that this screen is the highest resolution mobile panel to date.

According to the Korean company, this display will enable smartphone users to view full HD content in the same quality as on HDTVs and monitors. This LCD panel is based upon AH-IPS (advanced high performance in-plane switching) technology that features a massive 440 ppi pixel resolution (iPhone 4S’ Retina Display features 326 ppi) and 1920 x 1080 screen resolution.

LG said that at this high pixel density, the human eye is unable to distinguish between individual pixels and that its AH-IPS panels also displays the original colours of images highly precisely. In addition, this touchscreen sports wide viewing angles, stable display image as well as a rapid response speed when touched.

The company’s new 5" screen also features 16:9 widescreen aspect ratio and is 0.5" larger, as well as 2.2 times denser in pixels when compared to LG’s 4.5" panel at 329 ppi and 1280 x 720 resolution, which it replaces.

Besides this new display, LG also announced (translated using Google Translate) that it has surpassed the 3000 000 global sales mark in LTE (4G) enabled smartphones.

“As smartphones become increasingly valued for how well they do multimedia and with the rapid growth of LTE enabling faster large file transfer” said Sang-Deok Yeo, CTO and executive vice president of LG Display. “With the world’s highest resolution smartphone display, LG Display continues to remain a step ahead in developing the most innovative in display technology products.”

LG’s new 5" full HD LCD panel is expected to be released during the second half of 2012, and will be on exhibit for the first time at SID (Society for Information Display) 2012 Display Week, which kicks off on 4 June in Boston. The company has not revealed in which new models these displays will be introduced in first.
