LG Display today provided a preview of LG's G3's 5.5-inch 2,560 x 1,440 display and its record 538ppi resolution. The new 5.5-inch Quad HD (QHD) AH-IPS LCD panel for smartphones was certified as a QHD display after passing verified tests by NEMKO, the Norway-based international testing and certification organization for electrical products.

The certification comes shortly before the new Quad HD LCD panel will be unveiled with the forthcoming LG’s flagship smartphone to be launched in the first half of the year.

The certified 5.5-inch QHD AH-IPS LCD panel has 2560 x 1440 pixels, four times the image resolution of HD panels and 1.8 times higher resolution than a Full HD panel. With 538 pixels per inch, this panel also meets the 100 percent RGB color reproduction standard.

This is an ultra-slim panel with a mere 1.2 mm thickness and has a 1.15 mm bezel, which will be the narrowest available and 0.05 mm less than panels introduced last year.

In addition, LG says the panel has achieved the same level of brightness as a Full HD panel. Although it is difficult to raise penetration ratio in higher resolution panels since they have more pixels, LG says it achieved higher brightness by improving the penetration ratio through enhancing the pixel structure design and aperture ratio in the LTPS backplane.

The display will go into mass production shortly, according to LG.

KDDI has also just launched the first QuadHD (QHD) phone solely for the Japanese market. The Isai FL model made by LG. This one may may give us an idea of what LG's eagerly-awaited G2 successor will be like spec-wise, too. The Isai has some of LG's Knock functions and will come with a 13-megapixel camera, 3,000mAh battery, 2GB of RAM and a quad-core Snapdragon 2.5GHz CPU:
