Plasma TV Overview:


Plasma television technology is based loosely on the fluorescent light bulb. The display itself consists of cells. Within each cell two glass panels are separated by a narrow gap in which neon-xenon gas is injected and sealed in plasma form during the manufacturing process. The gas is electrically charged at specific intervals when the Plasma set is in use. The charged gas then strikes red, green, and blue phosphors, thus creating a television image. Each group of red, green, and blue phosphors is called a pixel. Plasma television technology eliminate the need for the bulky picture tube.

LCD TV Overview:


Basically, LCD panels are made of two layers of transparent material, which are polarized, and are “glued” together. One of the layers is coated with a special polymer that holds the individual liquid crystals. Current is then passed through individual crystals, which allow the crystals to pass or block light to create images.LCD crystals do not produce their own light, so an external light source, such as florescent bulb is needed for the image created by the LCD to become visible to the viewer. Unlike standard CRT and Plasma televisions, since there are no phosphors that light up, less power is needed for operation and the light source in an LCD television generates less heathen a Plasma or traditional television. Also, because of the nature of LCD technology, there is no radiation emitted from the screen itself.

PC connectivity

Less common but still included on many models

More common than with plasma

Other features

Varies per model

Varies per model

Motion blur caused by display


Difficult to discern on most models, although subject to more blurring than plasma. 120Hz and 240Hz models subject to less motion blur

Black-level performance (depth of “black” displayed)

Varies, although excellent on many models.

Varies, although generally worse than plasma on many models. LED backlights with local dimming offer significantly deeper blacks.

Color saturation

Varies, although generally a bit better than LCD due to black level and off-angle advantages

Varies, although the best models can equal the best plasmas


1080p is standard in all but entry-level models.

1080p is standard in all but entry-level models.

Off-angle viewing

Excellent from all angles

Image fades slightly when seen from extreme angles from sides or from above or below

Reflectivity of screen

Glass screens can reflect lots of light, so may be an issue in very bright rooms. Some models have glare-reducing screens that are more or less effective

Matte plastic screens usually reflect less light. Some models have screens that are actually more reflective than plasma



Now its up to u,which product u will like to have…………….
