First, it was Plasma vs. LCD. The inherent disadvantage of Plasma TVs however, caused manufacturers to invent. The picture quality of Plasma TVs are great, but they have too much power to attain it. In the modern world where energy sources are scarce devices ought to be power efficient. The Plasma TV was scrapped, and new technology is needed.
LED or Light Emitting Diode is not a new technology. LED bulbs have been used in place of light substances because of their low power consumption. They can be readily integrated with electronic circuits making them the perfect replacement for incandescent and fluorescent lighting in circuits.
Plasma TVs offered better picture quality than LCD TVs since the panel can produce its light. The panel consists of several cells that contain a different gas or plasma. This plasma glows to the desired color when current is passed through it. Meanwhile, LCD TVs must get a back-light because the panel cannot produce its light. This makes LCD TVs less effective because the light is not properly scattered.
LED TV manufacturers borrowed the idea of creating a panel which can produce its light from Plasma TVs. But instead of using plasma cells, Light Emitting Diode TVs contain LED cells. Each cell contains three LED, colored green red and blue. Then any combination of these three colors produces all colors in existence, recall. Passing intensity accomplishes the combination of colors on both LEDs. This results in a high color accuracy for all LED TVs.
Light Emitting Diode TVs instantly became popular and the LCD vs. LED debate started. LED TVs are more expensive than LCD TVs although they consume less power. For the time, however, the expense of electricity doesn’t balance out the expense of the LED TV. But it is expected that this new tv will become cheaper in the future.
There are some confusions over led or lcd . LED-backlit LCD TVs are LCD TVs only they are currently using LED as back-lights. They are cheaper and also consumes less power, but the image quality is not as great as Light Emitting Diode TVs.
If Plasma vs. LCD involves price over electricity consumption, LCD vs. LED involves power consumption over image quality. If you want a television which consumers power and provide a better image quality, then your choice should be the LED TV.
