Advantages of LED TVs
What is an LED TV?
It is an improvement on standard LCD display technology. In an LCD TV, two separate panels are fused together, one of which contains liquid crystals which emit or block light which comes from a source in the rear of the television. When LCD technology first evolved, these light sources were fluorescent; in an LED TV, fluorescent lamps have been replaced by light-emitting diodes (LEDs), which offer a number of advantages you should be aware of if you're in the market for a new TV.
LED vs. LCD TVs: A Comparison
LED TVs offer a number of improvements over standard liquid crystal display technology, including:
- Improved contrast. Some LED TVs use a technology known as local dimming, in which certain regions of the screen are left darker when displaying blacks and other dark tones. This results in improved contrast, which gives a sharper picture.
- Slimmer profiles. Because LED lighting technologies take up less space than fluorescent lamps, LED TVs are even slimmer than LCD TVs, which are already slim compared to plasma televisions.
- Light weight. Compared to plasma televisions, both LCD and LED televisions are lighter, giving you more flexibility in terms of set placement and mounting.
- Superior color representation. LED TVs are capable of adding slight color alterations to white light, creating more accurate color representation than you would get from a conventional LCD television.
- Reduced power consumption. Light-emitting diodes are extremely energy-efficient, and have longer lifespans than fluorescent lights. This results in diminished electricity consumption, which can translate into significant savings on your home energy bills.
While LED TVs are superior to standard LCD TVs in these regards, they do tend to be more expensive. If you're looking for sharp, crisp pictures with excellent contrast and brilliant color, they are worth the extra investment. Also, keep in mind that you will save energy over the lifespan of the television, which will offset the extra up-front investment you'll make when you buy an LED TV. The difference in price tends to be fairly modest, though, so an LED TV may be a better long-term investment if you want to enjoy the advantages of liquid crystal display technology.
