Their differences are found in the way in which they display their pictures.
Plasma displays uses a matrix of tiny gas plasma cells that are charged by precise electrical voltages to emit light and hence to create the picture image. In other words, each picture element in a plasma TV display acts as a miniature light source.
Liquid Crystal Displays (LCD) panels - work by trapping a liquid crystal solution between two sheets of polarized glass. When an electric current passes through the liquid crystals, they change the polarization of the light passing through them in response to the applied voltage – as a result of which, more or less light passes through the polarized glass to reach the face of the display. LCD panels do not generate light - rather they filter or subtract light generated by a back-light source to create the image on the panel surface.

So which is better? The answer to this question depends upon what you plan to use TV for. Do you just want to use it to watch movies and television? If so, then a plasma TV might be best, because they are capable of a higher better color saturation and contrast than their LCD counterparts and for displaying moving images. If you plan in spending a lot of time showing digital photography or plan on using the monitor with your computer, then a LCD display might be better suited to these purposes.

Different technologies:
"The basic idea of a plasma display is to illuminate tiny, colored fluorescent lights to form an image. Each pixel is made up of three fluorescent lights -- a red light, a green light and a blue light. Just like a CRT television, the plasma display varies the intensities of the different lights to produce a full range of colors."
"It turns out that liquid crystals are closer to a liquid state than a solid. It takes a fair amount of heat to change a suitable substance from a solid into a liquid crystal, and it only takes a little more heat to turn that same liquid crystal into a real liquid. This explains why liquid crystals are very sensitive to temperature and why they are used to make thermometers and mood rings. It also explains why a laptop computer display may act funny in cold weather or during a hot day at the beach! "

I think LCD's have better pictures and they last way longer than Plasma's. Plasma's are put together cheap and aren't expected to last very long.
I would in a department store and Plasma television's are always being returned and most plasma buyers are now buying LCD's. So I would go with an LCD anyday.

the quite some operational variations are that Plasma TVs use extra electrical energy than liquid crystal show TVs, are much less confusing to "burn-in" (created ghost photos from durable displayed photos), do fade in brightness with age, and are many times dearer than liquid crystal show TVs. Plasma TVs notwithstanding have the brightest and clearest reflects of liquid crystal show TVs have a shrink to the dimensions they'd be made to (i think of that's now forty two"), could have pixels flow undesirable (which capacity they do now not replace to the the main suitable option shade displayed interior the image), and would have "blurry" action (brought about via gradual replace of pixels.). they do now not be afflicted by burn-in like Plasma and CRT TVs, are fade-resistant, and are many times somewhat extra value-effective than Plasma. The brightness and readability is amazingly corresponding to Plasmas additionally.

Plasmas can have a picture burned in (games) and LCDs can lose pixels and even whole lines of pixels.
DLPs have none of these problems and much higher resolution.
