Plasma Vs LCD

Technology : How it works?
LCD : A matrix of thin-film transistors (TFTs) supplies voltage to liquid-crystal-filled cells sandwiched between two sheets of glass. When hit with an electrical charge, the crystals untwist to an exact degree to filter white light generated by a lamp behind the screen

Plasma : Plasma technology consists 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.

CONTRAST / BLACK LEVELS : Will it be able to depict best of shadows or darks?
: Even though there have been continuous research and development in LCD TVs black levels, only the best LCD televisions can really manage to crossover 1000:1 contrast ratio hurdle.

Plasma : Better than its counterpart; Plasma technology has certainly attained quite high contrast ratios, that fetches blackest black compared to the whitest white

COLOR ACCURACY : More lifelike images
LCD : Although most LCD displays handle it quite well; but it is inherently difficult pattern to maintain color accuracy and vivacity in comparison with PLASMA TVs.

Plasma : PLASMA certainly has edge over LCD as in plasma display; every pixel inherits all basic color of red, green and blue elements, which in conjunction create 16.77 million colors. That results into more rich and color accuracy.

VIEWING ANGLE : Which one has Best viewing angle?
LCD : Here again PLASMA outperforms LCDs. The best viewing angle of LCD HDTV till date is around 120 and 130 degree.

Plasma : Plasma has made much of 160° viewing angles. The 160° viewing angle for A PLASMA makes it best. Every angle is great viewing angle

FAST-MOVING VIDEO PLAYBACK : Fast action scenes! Which one is better?
: Again PLASMA takes the lead because of their exceptional capability for fast moving scenes and higher contrast levels

Plasma : Last couple of years has seen rapid improvement in “response time” of LCD TVs. but…. but …but still there is scope for improvement as they still carry slight trailer effect.

HIGH ALTITUDE : What if I move towards higher altitude?
: As LCD are predisposed to handle change in atmospheric pressure; Reason why they are preferred in Airplanes. As LCD are not effected In air pressure fluctuation

Plasma :igh altitudes (6,500 feet and above),difference in air -pressure emerges, which causes plasma displays to give out buzzing sound due to the lower or unfavorable atmospheric pressure

LONGEVITY : Life of my television? Or how many hours of viewing before backlight burn out?
: LCD on average last 50,000 to 65,000 hours; this is what manufactures have to say when asked about durability of their product. In fact an LCD will last long as its backlight does- and the best thing you have is that you can replace these bulbs.

Plasma : Plasma displays utilize current to induce combination of gases (i.e., argon, neon, xenon) due to which it glows red, blue or green. Being an active phenomenon; phosphoric element deplete over time.

SCREEN BURN IN : Why does it happens?
LCD : LCD Technology is not predisposed to “burn-in” of pixels as “Twisting crystals” technology rule-out premature aging of pixels

PLASMA : In case of plasma; PLASMAs are more prone to “burn in” or permanent etch of color in glass display- Although manufactures are doing their best to overcome this tendency and prolong the display life.

POWER CONSUMPTION : Please! I need to reduce carbon foot prints
: Due to florescent backlighting to reproduce images; LCDs consume substantially lesser power to operate than plasmas do; almost half the power consumed by plasma displays.

PLASMA : Plasma TV consumes almost double of electricity of LCD in bid to illuminate Each pixels on screen - even for the darker ones do. Though there is improvement in voltage consumption; still a plasma TV will consume around third more power than LCDs.

RESOLUTION : How many pixels? More pixels means more lucidity in the picture ? Got it?
: LCD HDTV possesses higher resolution per same size contrast to plasma. The least resolution of LCD measures 1366 X 768 - easily full HD resolution in 1080i or 720p.

PLASMA : Most of the PLASMA displays carry 1024 X 768 resolutions. Though this is not truly an HD resolution, but not everyone can figure-out the difference.

Cost : How much dent this purchase gonna make in my pocket?
LCD : Expect to pay a third as much more for a similar size PLASMA.

PLASMA : Costs less than LCD
