LED TV how they work and why they are the better choice

LED TVs have surfaced in the market bringing in a more enjoyable viewing experience for the users. It is true that LCD TVs are high definition televisions but the flaws that the televisions had were solved when the LED TVs appeared. This makes the new HDTV LED a better choice if you are planning to buy a new TV.

LED TVs still use LCD panels but instead of using cold cathode fluorescent lamps or CCFLs, LEDs use light emitting diodes to back light the television. LCD panels alone don't produce light so they need to use a back lighting material for the television to work. Since LEDs are smaller than the fluorescent lamps, they are more power efficient and consume less power ( up to 30% ). This will definitely help you when it comes to your electric bill. The panels used are also thinner than the fluorescent panels so LED TVs are slimmer and lighter. They can be as thick as one inch and they are easier to hang on walls. They are also more environmentally friendly and easier to dispose because there's no mercury in any part of the television.

LED TVs also deliver higher dynamic contrast because the LEDs that are used at the back of the television can be turned on and off independently unlike the fluorescent lamps. In this way, the television can give deep blacks that the plasma TVs gives and high brightness that LCD TVs deliver. You can enjoy high definition at its finest and can see rich colors that can give real life images.

Are you asking about the benefits of LEDs and how they work? LEDs are the newest and the best in the market nowadays. It surpassed the quality of plasma TVs and LCD TVs. This is the reason why many people are questioning the reliability and the efficiency of this high definition television.

LED TVs are high definition televisions that use LEDs as the backlight of LCD panel. They are technically called as LED-backlit LCD TVs. LEDs are light emitting diodes that are electronic semiconductors and they respond quickly when they are switched on and off. Electric current is needed for the LED to radiate light. This is the reason why LED s give higher contrast than other high definition televisions because the LEDs can be switched on and off independently giving a deep black and high brightness at the same time. This is called the local dimming that other televisions don't have. Before, local dimming is only available in backlit LED TVs wherein the LEDs are placed at the back of the panel. But when 2010 came, edge-lit televisions can now do local dimming too. So whether the television is backlit or edge-lit, high contrast ratio is assured.

The LEDs are also smaller than the fluorescent panels used in LCD TVs so they are more power efficient. They are also lighter than the previous panels making the televisions slimmer and lighter than other high definition televisions. This makes this high definition TV easier to hang on walls and more stylish when it comes to the exterior.
