Well, it’s not a simple matter of Plasma TV is better, or LCD TV is better. It really depends on your circumstances and preferences. Let’s talk about the differences and the pros and cons for each, as well as some of the misconceptions regarding these TVs, and hopefully that will help you in your decision making process.

Many people confuse Plasma TVs and LCD TVs because at a quick glance they look the same…they’re both flat screen TVs, with a thin profile, which can be mounted on a wall. They’re definitely both very cool technologies. They share other similarities, of course, such as screen resolution, input types, and a few others, but Plasma TVs and LCD TVs are totally different technologies, and there are differences that you should be aware of.

The purpose of this article isn’t to explain the technical operation of Plasma TV and LCD TV, but rather to talk about the practical, real world differences that will help you in your decision making process. A very brief explanation of the basic operation, however, might help in your understanding of why the differences exist.

The pixels in a Plasma TV consist of phosphor lined cells filled with xenon and neon gas. Each pixel consists of a red, green and blue component, which combine to reproduce the full spectrum of colors. Plasma TVs are an display technology, which means it’s self-lighting.

LCD TVs are different in the sense that they are a “transmissive” display technology. Meaning the light is not produced by the LCD crystal, but rather from a light source behind the panel. A diffusion panel is used to redirect and scatter the light from behind the LCD panel. The LCD Panel itself is formed by two transparent panels with a liquid crystal solution between them. Each crystal is a like a shutter that either allow a predetermined amount of light to pass through, or block light from passing through.

The latest on the Televsion ranges is the LCD TVs or Liquid Crystal Televisions. These are called as LCD TVs because here the Picture on the Screen is created by the tiny LCDs. These are far more advanced in displaying Pictures in the Televisoin Screen.

These LCD based Televisions deliver quite good angle of view, more than 170 degrees so that you get a fully undistorted view of the Picture virtually anwhwere from the Room. These LCD Televisions are desinged with adequate contrast ratio and this helps in viewing bright scenes or dark scenes in a dark room so that the scenes can be seen clearly without any difficulty.

The latest models of the LCD -TVs are equipped with a technology called Overdrive to eliminate the problems of the TV with respect to the Ghosting, and switching to a bright scene from a dark scene or vice versa. This technolgy takes advantage of the LCDs emit light of set intensity for more than 20milli Seconds in displaying pictures. This time added to the refresh time for the LCDs are usually enough for displaying the film based material in a better way than the conventional CRT based TVs.

To display Video material, that are shot at higher frame speeds these LCD TVs are provided with efficient technolgy that displays the moving object in “correct” places for as long as possible, and erase it from outdated places as quickly as possible on the panel. Due to the improvements in design the latest LCD TVs are able to overcome the Ghosting problem to a very great extent.
Another area of improvement in a LCD TV is the displaying the Colors and the resultant shades of the colors on the Screen. At present all the Colours in the RGB spectrum are displayed to give a live look to the Colour images, still these colour images lack the richness in their colour. So manufacturers are trying to find the ways of adding more colours and shades of colors on the Screen and also experimenting with extending colour reproduction of LCD Televisions.

As colour reproduction is the most distinctive aspect of a Television, research is still on to display more colours by using fourth, or even fifth and sixth colour in the optical Colour filter array,or to use two sets of suitabe narrowband backlights with slightly differing Colours, in combination with broadband optical filters in the Panel, and alternating backlights for each consecutive frame.

Thus more and more techniques are being invented and applied in the latest LCD- TVs which are going to increase our viewing pleasure.
