The apparent war between plasma and LCD TV’s has raged for some time. Traditionally, plasma models have offered the owners of a stunning array of technologies designed to provide the optimal display quality, in general, as well as the format of Liquid Crystal Display. The bone of contention for most of potential buyers is the price, plasma TV screens are generally associated with the premium price tag.
For most fans of the TV screen is the most important factor when considering that the purchase of TV. However, with the price of models of large screen running into four figures, many users have had to settle for a flat screen TV, which, in their eyes, at least, was a version of ‘economic’. The advent of technologies such as BRAVIA Engine, Sony and Philips Ambilight has leveled the playing field and helped to break significantly into sales of plasma TVs.
LCD TV and Plasma work using different technologies to provide the same visual effects. LCD TVs are built around the crystal cell that tighten and relax, when an electric current is applied to them. A backlight system saturates the cells and, like turn, the colors are not required filtered leaving only the desired color cells in place. Plasma screens including through the use of millions of pixels. The difference is that, when activated, the gas release cells that produce a specific color with bands of red, blue and green that are enclosed within the pixel.
Recent developments in liquid crystal technology have enabled manufacturers to build LCD screens that offer a vision of a quality comparable to that of plasma televisions. In particular the handling of fast moving action was a problem, many LCD televisions would leave the final image (commonly known as ‘blur’). Plasma screens have the upper hand in this case, as each pixel is individually activated. Another area where plasma has opened the way was the angle of view as they are capable of producing sharp images, at extreme viewing angles. LCD has made great progress in this field with many manufacturers quote viewing angles of 178 degrees in the region, while maintaining the quality of the images sharp.
The main drawback with plasma screens is the weight and thicker, which makes them heavier and thus more difficult to mount on the wall.
The most recent developments in LCD technology has delivered to the LED production process mainstream. Producers of TV you can use an LED backlight instead of the standard Cold Cathode Fluorescent Lamps (LCD-CCFL) used in most LCD TVs. The LED backlight has a number of advantages over normal TVs indcluding CCFL backlight consumes less power and brightness levels are higher. LED-backlit LCD TV’s typically have a duration longer than their LCD counterparts and are more efficient than plasma screens. Moreover, cells LEDs can be switched on and off more quickly than traditional light bulbs liquid crystals that can produce both higher light output, extraordinarily high contrast ratios and a wider range of deep blacks (Sony has cited its 40ZX1 model as having a Dynamic Contrast Ratio of 2,000,000:1).
Considering the rate of development is easy to see why LCD is rapidly replacing plasma as the preferred medium of display for consumers. Sure, the price of LED TV is still relatively high, however, the producers begin to see healthy returns on their investment, prices will drop. Plasma TV will be with us much longer?
