The former has a resolution of 2560 x 1700, the other draws notice for its thickness
Since the 2013 edition of the Consumer Electronics Show is almost here, it stands to reason that information will leak about what products will show up there.LG is the one on the radar right now. The company will have many displays on show, two of them suited for laptops.
One of them, measuring 13.3 inches, didn't get its resolution mentioned for some reason (either 1920 x 1080 or 2560 x 1700), but it did get points for its thickness of just 2 mm / 0.07 inches.
The other panel, with a diagonal of 12.9 inches, is an AH-IPS screen with the QSGA resolution (2560 x 1700).
Both of them are to be used in ultrabooks and whatever other mobile PCs companies can think of. Particularly large tablets may use it too.
