LCD vs LED Televisions. What’s the difference?

You may have recently discovered that many newer televisions have an LED (Light Emitting Diode) display. LED TVs are the latest generation of LCD flat panel displays and offer noticeable improvements in picture quality over the traditional fluorescent bulb backlit panel.

LED TVs are technically a member of the LCD family because both ordinary LCD TVs and LED TVs have the same liquid crystal display. The difference between the two is in the way they are backlit. LED TVs offer much improved backlighting techniques which changes the picture quality drastically.

You may have also noticed that the LED TV is much slimmer. LED TVs have the capability to by manufacture in much slimmer sizes than traditional LCD televisions.

The slim design of the LED TVs is not the only advantage over the traditional LCD TV. The backlighting on the LED televisions is much more accurate in terms of black levels, and color. There is a much wider range of viewable colors on LED TVs. This results in much more realistic colors when compared to the technology of traditional LCD TVs.

Picture Differences
Ordinary LCD displays handle black levels much differently than LED displays. The main difference is that traditional LCD TVs always have the backlight on and have to twist the crystals into a closed position to create black areas. This often results in a loss of detail and a lower contrast ratio. Some LED TVs use local dimming to handle black levels. This technology offers a much improved way of handling black levels. Backlighting can be controlled in dark areas of the picture, resulting in better detail and darker blacks in dark scenes. In some dark scenes, LED TVs have the capability of completely switching of the light in areas where a pure black is intended.

Another thing to note is that LED TVs do a much better job over traditional LCD TVs in terms of the viewing angle. Traditional LCDs lose contrast when viewing from an angle. LED technology has improved that significantly.
