LCD vs LED vs Plasma 2013: Market
Year Introduced to General Public
LCD screens have been used as a television for a long time now, since 1988. Sharp introduced the first commercial LCD television in 1988 at a size of 14". Due to size constraints and low refresh rate, it took LCDs until 2007 to surpass CRTs in worldwide sales.
While being present before in the display industry, the first 42” television was introduced by Fujitsu in 1997. Plasma TVs had a fast growth initially because they were much bigger than the current LCDs and had a faster response time. That growth stagnated quickly though, LCD sales surpassed Plasmas in 2006.
The first edge-lit LED TV was introduced by Sony in 2008. Because they are just an improved LCD screen, they are replacing normal LCD TVs rapidly.
Positioning inside the same brand
Manufacturers are abandoning the LCD with a CCFL backlight. Some brands even stopped making them in 2013. This was expected because an LED backlight is better in all aspect over a CCFL backlight. The edge-lit LED backlight represents nearly all of the mid and high-end models. Only very few company offers them in a full array matrix configuration and they usually have them only on their highest priced model because the performance improvement is very marginal (you can find the complete list of full array LED TVs for 2013 here). The positioning of plasma TVs has not changed since a few years, they are still available for mid and high priced models.
A good way to see how a technology performs is to look at its sales figure and what the others are buying.
LCD screens (both CCFL and LED backlight) account for the big majority of sales worldwide today. Plasma is growing slightly, but still represent only a small portion of all the HDTVs sold (less than 10%). The slight increase is a bit surprising, because a few years ago everyone thought plasma was dying. In Q4 2013, Panasonic announced that it will stops producing plasma TVs and will concentrate on the next technology. This leaves only 2 manufacturers of plasma left: LG and Samsung.
There is a major shift in the technology of the backlight of the LCD screens since 2010. The LED backlight is replacing the old CCFL backlight, and now accounts for the majority of the LCD screen sold. Most of the LED backlight shipped is edge-lit thought, not full arrays. There was quite a buzz around full array matrix LED backlight in 2010, but now companies are getting out of it due to higher cost and marginal picture quality improvement.

|Plasma||Between 42" and 65"|
As mentioned before, it is very hard to build a plasma display of a small size due to the limit constraint on the size of the cells. Therefore, the smallest plasma TV available to buy is 42". Also, the biggest available is 65". LEDs offer the full range of sizes, from very small 20" TV to extra-large 100".

- More prone to image retention (even if it is only temporary now)
- They do not get very bright and usually have more reflections, so they are not suitable for bright living rooms (which make them also look bad in a retail store)
- They are bulkier
- Slight buzzing noise
- And most importantly, LEDs picture quality are good enough for the majority of people
