Modern technologies make it possible to create a technique that seemed fantastic ten or fifteen years ago. The most popular today are LCD and LED TVs, which give the clearest and brightest picture, as well as having a large screen diagonal. So which of these TVs is better and how do they differ from each other?
The difference between LCD and LED
LED technology first appeared on the market in 2009 and rapidly gained great popularity - today all major manufacturers produce several lines of LED TVs. In fact, they are ordinary LCD panels, but with one difference - LED TVs have replaced the traditional fluorescent backlight with a backlight powered by LED elements in the form of luminous diodes.
Replacing the lighting elements has significantly improved the quality of TVs, but these changes are not revolutionary.
The quality and quantity of improvements that appeared after replacing the diodes are directly related to the type of LED backlighting. There are two types of LED lighting - simple and inexpensive side lighting and expensive back lighting. The side lighting uses exclusively white LEDs, while the back lighting uses green, blue and red.
In addition, the colored backlight elements are placed directly behind the LCD panel, which turns them on based on the current image color. This allows for extremely high levels of contrast and picture brightness that cannot be achieved with LCD TVs. Both side and back lighting create the latest and previously unattainable possibilities for modern television technology.
What's better?
Unlike LCD TVs, TVs with LED technology significantly save energy, consuming half the expensive electricity. In addition, they are more environmentally friendly and safer for their owner, as LED diodes do not contain mercury - unlike traditional screen backlight lamps. Also, LED technology has made it possible to produce really thin panels, the thickness of which is less than ten millimeters.
LED TVs are often referred to as picture TVs because they are difficult to distinguish from a real work of art when the picture is frozen on the screen.
LED TVs, in comparison with LCD screens, have higher contrast ratios - in some modern models, the contrast and image clarity characteristics are prohibitive (this applies only to backlit TVs). LED TVs have one drawback - unlike LCDs, their price remains quite high, but manufacturers promise to make them more affordable for most consumers in the near future.
