Benefits of LCD

Brightness

Brightness in LCD and Plasma screens is expressed as candelas per square meter (cd/m2). The brightness of plasmas is approximately to 100 cd/m2. LCD TVs however typically have a brightness rating of 500 cd/m2. This means that more the brightness more the clarity in the picture quality.

Resolution

LCD TV delivers exceptionally sharp images. The 2 mega pixel Full HD (1920 x 1080) and 1 mega pixel WxGA (1366x768) resolution panels, guarantees the sharpest visuals even in small screen sizes.

No Reflection

Because plasma Tvs employ phosphors for imaging, they are susceptible to glare from indoor and outdoor light. LCD Tvs don't have this problem, they create images by shuttering light through tiny color filters and generally handle annoying reflections from open windows or nearby lights with no difficulty.

No Burn In

Burn in is what happens when an image stays on a plasma screen for an extended period of time. LCDs are not at all susceptible to burm in while Plasma Tvs are vulnerable.


Lifespan

Typical plasma TVs have a lifespan of 20 yeqars of usage if you have the set on for 4 hours. The lifespan of an LCD TV is typically about 40 years running 4 hours daily.

Power conversion

Because the crystals in LCD TVs do not produce light the technology is labeled as "non-emissive" which means it does not give off radiation like the CRT. Cold cathode light sources, like fluorescent tubes which use only a little power, are used to illuminate the image. LCDs also use less power than plasma televisions, because plasma requires powering hundreds of electrodes to stimulate the phosphors.

Lightweight

Plasma displays are fairly heavy and may need additional support to be mounted onto a wall. LCD TVs weigh less than comparably sized plasma TVs.
