LG smartphone display uses AH-IPS to reach 440ppi
LG Display has introduced a full HD LCD screen for smartphones. The new display packs a higher pixels-per-inch count than the 326ppi Retina Display used on the iPhone, and is a 30 percent increase compared to LG's own 4.5-inch predecessor. Based on an Advanced High Performance In-Plane Switching (AH-IPS) technology, the screen can push out 440ppi at a resolution of 1920x1080. The previous 4.5-inch LG screen could only muster 329ppi and a resolution of 1280x720, by comparison. A wide viewing angle, stable display image and rapid response speed when touched is claimed by LG, with a brighter light transmission and low power consumption to help with outdoor viewing.
With claims that LG and others are involved with making a four-inch display for the next iPhone, speculation may turn to how Apple and other phone manufacturers will take advantage of this display. However, it is currently only available in a five-inch size at this time and will more than likely find a home on an Android flagship device sooner. If Apple was to employ it at all, it would be more likely to find its way into a large iPod touch, which has been previously rumored on occasions.
The four-inch full HD LCD panel is expected to be out during the third or fourth quarter this year, with a demonstration at SID 2012 Display Week in Boston from June 4.
