PLASMA V/s LED v/S LCD TV

CRT TV are done now and they have been a faithful companion till now. The day when I decided
to go for a new TV I had options of Plasma, LED and LCD. I did a plenty of research online
for the options that I should go for. I thought its better to summarize this information
in the way which will be helpful for a consumer like me for simplifying his decision process.

TECHNOLOGY:
Plasma TV: Plasma technology consists of hundreds of thousands of individual pixel cells, which allow electric pulses (stemming from electrodes) to excite rare natural gases-usually xenon and neon-causing them to glow and produce light.
LCD: A matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells.For LCD HDTVs, however, the liquid crystal screen does not illuminate, requiring a separate light source.
For LCD its achieved using cold cathode fluorescent lights (CCFLs) to illuminate the screen. 
LED:
LED is one step ahead of LCD with same tech instead of CCFL it uses LED back lighting.

CONTRAST/BLACK LEVEL                            Winner: Plasma
Plasma:
To achieve full black level Plasma has to just turn off the pixel which results in very  high contract
rations and best black levels, some manufactures claim 30,00,000:1 dynamic contrast ratio.
LCD:
LCD tv has to spend maximum power to turn its pixel blacks thus lagging behind in achieving the required
black levels/contrast ratios. The best in bredd LCD claim only 1,00,000:1 dynamic contrast ratios.
LED:
LED has made improvements achieving DCR 9,000,000:1 over LCD but still lags behind Plasma

BRIGHTNESS:                                                  Winner: LED
LED due to its extra LED Back light helps to achieve High brightness as compared to Plasma and LCD.
Plasma has better Brightness as compared to LCD.

COLOR ACCURACY:                                       Winner: Plasma
Plasma TV color richness and naturalness will prevail in rooms with lower to normal lighting - yielding a more realistic picture. LED LCD TVs perform better in very brightly lit rooms due to their inherent anti glare technology and brightness.
Check all the three TVS side by side with same video being played LED makes first impression, but if
you just give a thought that you will be watching this picture at least 1-5 hours a day the extra bright
colors may give irritation to your eyes. Plasma give more soothing TV experience with Natural colors, however LED colors are more artificial and extra bright.

VIEWING ANGLE:                                             Winner: Plasma
Plasma achieves 180 degree of viewing angle easily, LCD and LED have around max 120.
         
COMPUTER USE:                                              Winner: LCD
Earlier Plasma TV  had burn in problems, as computer have more static images it was not recommended
to user Plasma Monitors. But now days Plasma TV no longer have burn in issues, however LCD scores
top as Computer use over LED and Plasma.

FAST MOVING VIDEO:                                    Winner: Plasma
Plasma manufactures publish 600hz refresh rate and that of LED/LCD is between 120-240Hz. If you
check out any sports on all the TV's side by side, Plasma will give you the best experience.
         
SCREEN GLARE:                                               Winner: LED
Plasma TV is more suitable for normal lighting, incase of bright light room LED/LCD is better

 LIFE:                                                                    Winner:  ALL
Earlier LCD/LED Tvs where considered having long life, but now days with advance in Plasma technology
all the types have similar life.
       
SCREEN BURN IN:                                            Winner: LCD/LED TV
Plasma TV had Burn In issues if a certain static image was retained on the screen for several hours.
This is not the case in LCD/LED TV, however Plasma TV also no longer have this issue with modern
technology incorporated into them.

PRODUCTION SIZE AND COST:                     Winner: Plasma
A 42 inch Plasma TV will cost you around 30-50000, however same LCD/LED tv will be in higher range
above Rs. 50000.Plasma TV have been considered best for Large screen size as compared to LCD/LED TV
         
POWER CONSUMPTION:                                   Winner:  LCD/LED TV.
Here LCD TV tops with more Energy saving followed by LED and then Plasma.

HEAT:                                                                       Winner: LCD
Plasma TV generate more heat as compared to LCD/LED TVs.

3D:
With 3D tech Plasma has certain advantages such as High Refresh rate, Natural colors and Big screen
sizes. LED TV also has certain advantages like Brightness that is important for 3D.
       

Final verdict
Plasma TV with new modern Tech is the clear winner with comparison to LED TV.
LCD TV i think should be ignored totally.
1 Plasma
2 LED
3 LCD

Before making a choice few points to ponder
1. High Brightness of LED TV might be good for TV experience perspective, but it might turn harmful
    for your eyes if you have a small size room as its like looking into a direct source of Light.
2. Check the LED and Plasma TV side by side and think from a perspective that you will be watching
    the TV for at least 1-3 hours and then choose.
3. Panasonic manufactures the best Plasma, but now days LG also has very good Plasma TVs. For LED 
   TV  Sony, Samsung and LG brands are popular.
4. Plasma TV are hard to find in Display in many showrooms as they are less costly and hence have less
   margin for the Sales. If you specifically ask the Salesman he might say its old tech and go for LED
   remember he is trying to sell a more costly product to make more profits. This is insider info.
