When choosing between LCD, Plasma or OLED, be aware of the differences. Although initially Plasma and LCD monitors may seem alike, they are quite different in the material that they are composed out of. The plasma TV, as the name may suggest to some, is composed of tiny gas plasma cells which function through exact and precise charged electrical volts which create a picture. The LCD on the other hand, or otherwise known as liquid crystal display, feature liquid crystals which are forced between two glass plates. To create the variety of images that we see displayed on the screen, these particular liquid crystals are adjusted by level of charged electrical energy being applied to crystals at any one time. OLED stands for Organic Light Emitting Diode. Carbon is used primarily in OLED displays, and since it is also found in many ‘organic’ products such as substances with sugar, wood and the majority of plastics, the word organic comes into play. One of the major advantages of utilizing an OLED over an LCD or Plasma would be the almost instantaneous response times, exceptional contrast levels and a wide viewing angle. OLED operates by having a layer of organic material compressed between a cathode and an anode (conductors) that will produce electro-luminescent light when charged. OLED’s have been known for their economically friendly production, consuming less power and increasing popularity. What about LCD and Plasma? Since they are both pictured as ‘flat-screen’ televisions, it’s a good idea to get a grasp of the differences and find out which one is better suited for particular environments. Neither plasma or LCD’s will provide a bargain, but the price-to-size ratio for both types of TV’s will generally fall in the same price bracket. LCD’s usually cannot display black as well as plasma can, since the colour emitted looks closer to dark grey. The backlighting of an LCD screen will generally be less efficient than that of plasma, although this will vary depending on the manufacturer and the size of the TV. However there is a known issue with plasma TV’s, a phenomenon called ‘burn-in’. This occurs when a television shows a still image or icon that is displayed to the viewer for so long that it leaves behind an imprint of where it was even though the screen has changed to something else. For example, if a timer of some sort or stock ticker continuously plays on the TV display, it may be burned into the plasma. Manufacturers have taken the initiative to counter this problem by setting default contrast levels, building in screensaver technology and providing information in instruction manuals. Most importantly, what about viewing high definition videos? Which TV would be the preferred choice? In this case, both TV’s are able to effectively display a high-def signal. However with an LCD you will need at least a 1280 x 720 pixel resolution to enjoy the real experience of HDTV screening. Both plasmas and LCD’s can be used as computer monitors, with compatible DVI ports and are able to hook up to game consoles without any problems. Although OLED, LCD and Plasma TV’s all have their differences in how they operate and work, if you’re looking for a high quality viewing experience, either of the three will work fine.
