How LED TVs Work
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 헤라카지노 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.
