Though outer appearance of plasma TV and LCD TV is similar but the difference between plasma and LCD TV is in their technologies which make them altogether different from each other. To review the difference between both the TVs you should about their working individually.
Difference between plasma and LCD TV : a comparative study of technologies
Plasma TV: The technology used in Plasma TV is based on the fluorescent light bulbs and its display is based on cells. During the manufacturing process of Plasma TV neon-xenon gas is injected and sealed in the narrow gap between the two glass panels of each cell. The plasma TV creates images when the gas in these cells get electrically charged and strikes with blue, red and green phosphors in these cells known as pixel. Due to the formation of images by burning of phosphors Plasma TV had eliminated the need of electron beam scanning and bulky picture tube of traditional TV but the problem of screen-burn of static images and heat generation of traditional TV still exists.
LCD TV: The LCD panels of the TV are made of two polarized and glued together layers of transparent materials one of which is enabled it hold the liquid crystals by coating it with special polymer. Images are formed in this TV by blocking or passing the light through these crystals when current is passed through them individually. But the images are made visible through an external source like florescent bulb as LCD crystals do not emit any light. So because there is nothing to light up like in Plasma TV, LCD TV needs lesser power to operate and emits lesser heat and no radiation as compared to Plasma TV.
Comparative difference between Plasma and LCD TV
Advantages and disadvantages of Plasma TV as compared to LCD TV
Plasma TV has better contrast ratio, better color accuracy, and ability to provide deep black images, wider side-to-side viewing angle and better motion tracking in fast motion pictures than LCD TV.
Apart from all these positive points there are certain negative points about Plasma TV as compared to LCD TV. Plasma TV has to be used in darkened room due to its less brightness, burn-in of static images, the reflective screen surface will reflect the light from other sources in the room, does not performs good at higher altitudes and consumes more energy and produces more heat than LCD TV. This is a major difference between Plasma and LCD TV.
Advantages and disadvantages of LCD TV as compared to Plasma TV
LCD TV has cooler running, no burn-in static images, more brightness in images, no problem in using at high altitudes, lighter in weight, less reflective screen surface, can be used for 3D display and longer display life as compared to Plasma TV.
LCD TV has low contrast ratio, side-to-side viewing is affected, not good at fast moving images, though burn-in susceptibility of static images is absent but there are possibilities of burning of individual pixels and expensive TV than Plasma TV.
Thus you can easily choose ether of the two after going through the difference between Plasma and LCD TV provided in this article. In fact, you should consider the difference between Plasma and LCD TV before choosing any of them.
