In-Plane Switching

Plasma Panels

Plasma panels are on their way out because they have a couple of serious downsides. Primarily, they generate a lot of heat because they burn phosphors to display images. More heat generation means more power consumption, so they're not as eco-friendly as other panel types. Also, static images on plasma panels can cause a screen-burn effect if left for too long. Earlier plasma TVs used to have shorter lifespans than LCDs, but this has since changed and only something you need to worry about when buying used. Either way, you can expect a minimum of 30,000 hours of use.

On the plus side, because plasma panels are used less and less their prices are down. If you buy plasma, you'll generally be able to get a larger television for less money—you just might make up that cost with your electric bill. Plasma panels are also known for their better contrast ratios, rendering of rich colors and deeper blacks, and little to no ghosting effects when displaying fast-moving images.

LCD Panels

LCD panels are the most commonly-used type of panel in flatscreen televisions today. They offer a lot of benefits, such as low heat generation, no static image burn (like you might encounter with a plasma-based display), and a greater brightness over plasma. LCD panels tend to be lighter in weight (than plasma), and you have a choice between active shutter and passive glasses when purchasing a 3D-capable model.

On the other hand, LCDs have never been great at rendering blacks or avoiding the ghosting problem with fast-moving images. Although the 120Hz and 240Hz refresh rate modes can help with this problem, this can make the motion in films look kind of like they were shot with a consumer video camera. If you're okay with switching between these modes when you're switching between sports and film, this isn't much of a disadvantage. LCDs are also prone to dead pixels, and it's fairly common to purchase a TV with at least one dead pixel. Generally many pixels have to die before a warranty claim can be filed, so if you have one or two dead pixels and it bothers you a lot you should exchange the TV before your exchange period runs out.

In-Plane Switching

LCD panels with In-Plane Switching (IPS) offer an advantage over standard LCDs and plasma panels. You may have noticed that when you walk to the sides of a flatscreen television the picture becomes lighter and, in some cases, begins to invert. This is because of the viewing angle is rather narrow on most TVs. LCD panels that offer IPS, however, generally have a viewing angle of 170 degrees. As a result, you can watch your TV from a greater angle and the picture will look about the same. If you've ever seen a recent Apple monitor, iMac, or iPad, you've seen a LCD panel with IPS.
