LED TVs are not a separate entity from LCD TVs but they are an improvement on them. LEDs are incorporated into the lighting of the LCD display, they replace the fluorescent tubing behind the screen that used to be used. The advantage of using LEDs is that they are able to produce a brighter image and use much less energy than the tubing.

Several manufacturers now manufacture these types of TVs and they are seen as a vast improvement features such as the color and contrast are vastly improved. One feature to look for that will distinguish between the better quality TVs is the power consumption of the LEDs. LEDs can be made using various materials and as such there is a large scope for difference, one way to find out the quality of the LED is to look at the power consumption of it, the lower the power the better the quality.

Currently there are two main types of LED placement for the lighting of the LCD display these are edge lighting and an array. Edge lighting places the LEDs around the side of the screen and disperse the light over the screen using an optical sheet. The array method places the LEDs in rows and lines behind it.

The quality of the LEDs used can also be seen in the time it takes for them to respond to color change this time is measured by the manufacturer and displayed as the response time, this is usually given in ‘ms’. The LEDs are timed to see how long it takes them to turn from black to white to black again.

LEDs as mentioned are much better at displaying dark scenes with not much light. They have a greater ability to display closer matched dark colors and as such the picture is much easier to view than with normal LCD TVs. An example of LED TV that’s capable of producing excellent image quality is the UNB8500 series from Samsung. If you wish to know more about it, make sure you check out the Samsung UN46B8500 review.
