An LED TV is the same thing as an LCD TV; that is, it uses both technologies to produce the picture on the screen. An LCD TV uses cold cathode fluorescent lamps, or CCFL, as the backlighting source. This lighting offers realistic colors and good brightness, but it fails to achieve great blacks and shadows. Therefore, TV manufacturers combine the CCFL backlight with LED technology to improve the picture.
The Benefits of LED Backlighting
LED lights achieve greater blacks and produce brighter colors. In addition, they provide better contrast ratios and deliver comparable picture quality to a plasma TV. Other benefits of LED TVs include:
- Slimmer design
- Better viewing angles
- Long lasting
- Use less energy
- Do not contain mercury
Types of LED TVs
LED TVs have one of two types of LED technology: edge lighting and full-array lighting. An edge-lit LED TV has small LEDs positioned around the panel and disperses the light across the screen. However, the light is more prominent around the edges, and the black levels are less dark. An LED TV with full-array backlighting has individual rows of LEDs behind the screen and produces brighter colors, greater contrast and a better picture.
LED TV Sizes and Options
LCD TVs with edge-lit LED technology have slimmer designs, yet both edge-lit and full-array LED TVs come in sizes up to 80 inches. Many of these TVs offer features such as Internet streaming, 3D technology and USB support. Full-array LED TVs have a feature known as local dimming, which shuts off LEDs in a certain area to promote greater blacks.
Even as TV manufacturers create newer technologies, LED TVs remain the popular favorite among buyers who want a great picture at a reasonable price. From LED smart TVs with Wi-Fi to LED 3D TVs, an LED television produces a bright picture and realistic colors for movie watching and TV viewing.
How Much is Too Much?
Even in this economy and this culture – where LED TVs are relatively affordable and increasingly commonplace – knowing how much is too much is always important. The price is often determined by the manufacturer and, of course, the distributor. Much like buying a car or a computer, it’s always wise to shop around for the best prices. As a general rule of thumb, you should be ready to spend upwards of about $300 to $400, but these too can vary.
What if I Want to Get Rid of an Older LED TV?
You should never throw any kind of electronic waste in with the rest of the garbage. In the case of CRT or LED televisions, there are electronics recycling centers that handle the safe and efficient disposal. If you are looking for the nearest center in your area, consult earth911.com for more information.
By ensuring the proper disposal of your LED TV, you limit your contribution to the growing problem of landfills. More importantly, your actions could yield renewable results that lead to less waste and more of a positive impact on the environment.
