At the SID 2011 exhibition in Los Angeles LG Display has exhibited a range of new LCD panels with ultra-high resolution, based on LGâ€™s AH-IPS LCD panel technology. LGâ€™s new panels include a new 4.5â€ť panel with 329ppi and an 84â€ť panel with 3840x2160 pixel resolution.
LG at SID 2011
AH-IPS stands for advanced high-performance in-plane switching (IPS) and was first utilized in Appleâ€™s iPhone 4 and the Retina Display. At SID 2011 LG has taken their AH-IPS panel technology one step further and integrated it into a range of LCD-panels from 4.5 inches to 84 inches, thus realizing extremely high resolutions.
LGâ€™s two new TV size panels in 84 inches and 55 inches shows LGâ€™s dedication to bringing higher resolution TVs into the living rooms. The 84 inch panel has a pixel density of 52 ppi (pixel per inch), which translates into something like 3840x2160 pixels (LG has not shared details about the resolution, only pixel density). The 55 inch panel has even more impressive 80ppi, which means that it also utilizes a resolution of 3840x2160 pixels.
LGâ€™s new high resolution LCD panels
LG Display also exhibited 10.1 inch, 7 inch and 4.5 inch LCD panels for mobile devices such as smartphones and tablets. The 10.1 inch panel has a pixel density of 150ppi – or around half that of Samsungâ€™s 10.1 inch tablet LCD panel.
The 7 inch panel has a pixel density of 212 ppi and the 4.5 inch panel has 329ppi (or 960x640 pixels), which means that it has the same pixel density as iPhone 4 – only in a larger format.
However, LG did not exhibit any new 9.7 inch LCD panels with high resolution. LG is supplying Apple with the displays for iPad 1 and 2 that use the 9.7 inch panel size. This does not mean that LG (and Apple) has no such panel planned for next generation tablets, and LG might have decided not to reveal the panel to keep details about Appleâ€™s iPad 3 secret.
Lastly, LG showcased a 27 inch panel with 109ppi, which means it has 2560x1440 pixel resolution..
