LCD Technology

Comparison of LCD TV and Plasma TV

There are million of arguments for this particular topic. Below are comparisons of the 2 technologies.

Difference Between LCD & Plasma TV

Plasma and LCD panels might seem similar, but the horizontal display and thin profile is really where the similarities end. While LCD displays, as it title indicates, liquid crystal screen are crystal sandwiches between two glass panel. Again, electric control voltage used to varying the liquid crystals. Plasma TV have marginally advantage over LCD in duration of black colour screen, which imply greater detail and contrast in dark-colored picture scenes. Manufacturer keep advancing with new technologies and production progress in generation to generation. Besides better contrast with greater capability to display ideal black, plasma displays have wider viewing angles than LCD displays. Viewing angle imply how far you are able to sit on both sides of display before the picture of display vanish.

For LCD display, some brightness and colour change occur when viewing angle is large (far from centre of display ). Plasma display have greater viewing angle contrast to LCD display. Manufacturer are advancing the lagging behind LCD display technologies to catch up with Plasma display technologies, and steadily changing with more and improved LCD display technologies going into the current market, where today that the viewing angles of a version of LCD display is equivalent or better then plasma display. Plasma create brighter colour also, compare to LCD display as a result of light leakage on LCD involving pixels which affecting its colour saturation.

Advantages of Plasma over LCD technology

LCD screens tend to has blur images in fast moving scenes in action movie or sport due to slow switching time of crystals from black to white. While this was true for older generation LCD screens, new models have improve significantly and close the gap between these two technology. The lowest the switching time for LCD, the better the image quality in fast moving scenes. Currently there is some manufacturer claim their LCD TV switching time as low as 2ms, while typically 6ms switching time will provide good fast moving scenes. Another advantage of Plasma is low price for screen size larger than or equal to 42-inch. This has changed recently where LCDs’ price for screen size of above 42-inch are matching or even beating plasma in both resolution and price.

Advantages of LCD over Plasma technology

Apart from being price competitive, LCD has the edge over plasma in several other key areas. LCDs tend to have higher native resolution than plasmas of similar size, in layman term, it mean more pixels on same area of screen. LCDs also consume less power than plasma screens with estimated power saving of more than 30 percents. Except for greener for LCD technology, it weight lighter than similar sized plasma TV and making it more feasible to mount on wall. The lifespan of LCD TV out-perform plasma TV where plasma screen would lose half of their brightness after more than 20,000 hours of viewing. While almost all LCD TVs have lifespan of 60,000 hours or more. However, newer version of plasmas have bumped up that lifespan to between 30,000 and 60,000 hours. Plasma TV prone to screen burn effect if static image left display on screen too long and resulting the ghost of image burned in permanently to plasma screen. Newer plasma TV less susceptible to this with improved technology. LCD screen do not suffer from this due to the picture is display via changing crystals.
