LG reveals 5 inch smartphone screen with Retina display besting pixel density of 440ppi

LG's new 5 inch display has a higher pixel density than the Apple iPhone 4 and 4S

LG has announced the world's first 5 inch Full HD LCD Smartphone panel that offers 1080p resolution and a 440ppi pixel density. The latter easily beats the 330ppi Retina display on the Apple iPhone 4 and Apple iPhone 4S and is made from LCD technology called Advanced High Performance In-Plane Switching (AH-IPS). This technology allows for wider viewing angles, improved brightness and fast response times when touched. The new display is said to give smartphone viewers the same viewing experience as those HD television viewers and those using HD computer monitors.

The new panel has a 16:9 widescreen aspect ratio and is a major improvement over the previous 4.5 inch panel which had 720p resolution and pixel density of 329ppi. Additionally, the new 5 inch display is 2.2 times denser in pixels and offers 30% more pixels per inch. And the AH-IPS technology used on the display makes individual pixels impossible for the naked eye to pick out allowing for precise reproduction of color. You might think that a panel that offers a brighter display would use more battery power, but no, that is not the case with the new LG display. The screen consumes less battery power than other displays in its class. The display will be released during the second half of this year.

LG Display Develops World's First Full HD LCD Smartphone Panel

5" Full HD display, creating perfect cloud computing environment

Seoul, Korea (May 28, 2012) – LG Display [NYSE: LPL, KRX: 034220], a leading manufacturer of thin-film transistor liquid crystal display, introduced today a 5" Full HD LCD panel for smartphones – the highest resolution mobile panel to date. Allowing smartphone users to view Full HD content in the same quality as on TVs and monitors, LG Display and its new panel significantly advances the cloud computing experience widely considered the next major internet trend.

LG Display's 5" Full HD LCD panel is a step forward past existing mobile display technology. The LCD panel based on AH-IPS (Advanced High Performance In-Plane Switching) technology features 440ppi and 1920x1080 resolution, providing for the first time Full HDTV quality on a smartphone. With 16:9 widescreen aspect ratio, the panel is also 0.5 inches larger, 2.2 times denser in pixels, and 1.3 times more advanced in ppi than the preceding 4.5" panel at 329ppi and 1280x720.

"As smartphones become increasingly valued for how well they do multimedia and with the rapid growth of LTE enabling faster large file transfers, our new 5" Full HD LCD panel is certain to prove a significant asset to the mobile market," 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."

The display solution of choice for smart devices, LG Display's AH-IPS is the technology behind the new Full HD LCD display. With the high density of AH-IPS, the naked eye is unable to distinguish between individual pixels. AH-IPS panels also express the original color of images highly precisely, and feature a wide viewing angle as well as stable display image and rapid response speed when touched. Finally, with its brighter light transmission and lower power consumption, AH-IPS is ideal for use in outdoor settings.

The 5" Full HD LCD panel from LG Display is expected to be released during the second half of this year, and will be on exhibit for the first time at SID 2012 Display Week in Boston starting June 4.
