Understanding the main differences between LCD & LED HD TVS

Finding a HD TV is often about more than just size and resolution. Today’s LCD HD TV has a new cousin, the LED TV. As the most popular type of HD TVs are LCD and LED HDTVs. To compare and understand the main differences between the two types of HD TVs, you must understand the screen sizes and how those play into which HD TV is which.

The type and size of HD TV can help determine which HD TV is for you. For example, if you need an HD TV that is less than 42 inches in screen size, the LCD HD TV may be the only option because the other types of HD TVs do not come in that screen size.

So what about LED? LED is making waves and fast replacing LCD HD TVs although LED TVs cost significantly more than traditional LCD TVs of similar sizes.

LCD – means Liquid Crystal Display is based on the same technology used in computer monitors today. LCD is backlit by CCFL lighting. Screen sizes of LCD HD TVs range from 19 inches to 65 inches. The advantages of LCD HD TVs include their energy efficiency over plasma HD TVs as well as their ability to display images well in lit rooms. LCD HD TVs would probably be suitable for use in rooms that will have continuous light instead of dark rooms as the image quality can look distorted in darker room settings.
LED – Light-Emitting Diode is similar to LCD HD TVs only that the backlighting technology is different. Where LCD HD TVs use CCFL backlighting, LED TVs use LEDs. There are two main types of LED TVs, the edge-lit LED TVs and full-array LED TVs. Edge-lit LED TVs are more common and have a thinner back size while full-array LED TVs are often more expensive and usually have larger screen sizes. LED TVs are available in screen sizes of 32 inches upwards. LED TVs have a number of benefits including brighter picture quality, thinner sized TV panels and considerably less power consumption. There are also some cons, LED TVs cost more and some models do not have improved picture quality than other HD TV model types. The LED TV is ideal for those who want the ultimate in viewing and understand the benefits of LED and its green features.

These 2 types of HD TVs are the main types of HD TVs that most will go for although there are other types such as the projector based HD TVs and plasma HD TVs although these are often rare and only available for special applications.
