We review many LCDs, but the reality is that we don't review very many different LCD panels. The reason is simple: there aren't very many LCD panel manufacturers. Most LCD panels come from one of the top three panel manufacturers: AU Optronics, LG Philips, and Samsung Electronics. While there are minor variations in panel quality, if you choose a particular panel model and put it in two different LCDs, overall performance is likely to be very similar. Differences between panel models can be much greater, however, especially if the underlying technologies are not the same.

Besides the panel manufacturer, there are three panel technologies in widespread use: TN (Twisted Nematic), PVA (Patterned Vertical Alignment), and IPS (In-Plane Switching). MVA (Multi-domain Vertical Alignment) is also around, but without getting into the details we'll just say it's somewhat similar to PVA. All of these technologies can also have an "S-" prefix, which stands for "Super" -- indicating the use of an upgraded version of the original technology. (Nearly all modern panels are S-TN, S-PVA, or S-IPS, but we won't worry about that.)
