In the past, Plasma TVs had a much better contrast ratio than LCDs. Plasmas were easier and cheaper to make for the larger screen sizes but advances in technology and manufacturing has evened out the playing field
Though the televisions with LCD technology are tagged exorbitantly, much higher than the regular tube models, there are several reasons why that extra cash pays off, the most important of which are outlined below:
Totally Flat Screens:
Traditional TV have a curvature built into their display screens and this could cause edge distortion, as well as shadows on the screen. Genuine Widescreen Performance:

The superior quality LCD displays can produce approximately 16 million unique colors, generating a remarkable depth of color that ensures excellent and accurate colors.

Moreover, there are multi-system LCD displays, which are geared to function with a range of several television signals, which includes PAL, NTSC and SECAM. Tests of LCD and plasma TVs have found that the average life expectancy for such devices are approximately 35,000 hours.
The LCD display is made up of a large number of picture elements, known in the industry as pixels. The number of pixels used in an LCD display will vary from hundreds of thousands to many millions, and the higher the number of pixels the better and sharper the display of the unit should be.That’s why if you choose to buy LCD you must consider what the advantage and is it equivalent with the price or not.
