What is an IPS display?

I was looking at tablets recently, and some of them listed an IPS display in their specs. These weren’t all top of the line tablets, by the way, but they were not junk either. Is an IPS display better in some way than a “standard” screen?

"IPS (In-plane switching) is a screen technology used for liquid crystal displays (LCDs). It was designed to solve the main limitations of the twisted nematic field effect (TN) matrix LCDs in the late 1980s. These limitations included relatively high response time, strong viewing angle dependence and low-quality color reproduction. In-plane switching involves arranging and switching the orientation of the molecules of the liquid crystal (LC) layer between the glass substrates. This is done essentially parallel to these glass plates."

IPS in plane switching. It’s nothing new, but marketing departments have recently discovered it, so it has become a buzzword. Basically IPS is a technology first brought to market by Hitachi in 1996. It’s a method of altering the direction of the pixels so that viewing angles and color reproduction accuracy are improved.
