Television has completely changed the way we view the world. It all started with the good old CRT TV - which though now obsolete, is still present in many American homes doing what it has so faithfully done for many years, delivering a TV picture that looks good. However, CRT TVs are bulky and in no way capable of delivering the big screen displays many are looking for in home entertainment. It is this that eventually led to the development of new flat panel TV technologies like plasma, LED and LCD.

These display technologies may appear confusing to the uninformed buyer, especially when it comes to the difference between LED and LCD TVs, with the former being the more expensive of the two, and the technology that most manufacturers and retails are pushing on the market. The reason is that being the latest, it is the one that supports higher mark-ups. It is thus important for anyone in the market for a TV to know the differences between these two different display technologies both to avoid falling into TV makers and retailers tricks, and equally important, to know which TV technology is best for your needs.

The following summarizes the main difference between LED and LCD TVs:

LCD TVs: Both LED and LCD TVs make use of a standard LCD display. What are commonly being referred to as LCD TVs, use a florescent backlight necessary to light up the display. This has an expected life of around 20 to 25 years, consume significantly less amount of power than regular CRT and plasma televisions and are available in a variety of sizes - going up to 65-inch and more. Main problem with CCFL LCD TVs is their lower contrast levels and the abrupt deterioration in color and contrast with off viewing angles. For this reason, many are starting to look at these LCD TVs as the worst of the breed.

LED TVs: As already indicated, these make use of the same display technology but instead of CCFL, use an LED backlight as the display light source. These are being considered by many as the best HDTVs for home entertainment, with a TV picture that supports higher contrasts, deeper blacks, and brighter color; they also consumer much less energy than their CCFL LCD TV counterparts. However, some of the cheaper LED lit TVs do not support the same viewing angles and screen uniformity as CCFL LCD TVs. They are also somewhat more expensive though prices have started to fall, but then, these are said to be more realizable and supports a much longer life span.
