"New TV is born! Love at first sight! Samsung LED TV, 2.99cm finger-thin slim, LED innovative light quality, Samsung LED TV." This is the Samsung TV slogan that is currently being popular in all major TV media. If you don't realize that there is something in the middle, then you are deceived. There are 1.3 billion people across the country, and I believe those who are aware of the problems will not exceed 300 million.
First of all, Samsung has "hit the rocks" in the UK because of similar advertising slogans, and was convicted by the British ASA organization (equivalent to China's General Administration of Industry and Commerce) for violating the advertising law. This is mainly because the so-called Samsung LED TV in Samsung's above advertisement is just a TV with LED backlight.
Because of the similarity between LCD TVs and LCD panels, the above problems also exist in the display industry. The LED displays currently advertised by some manufacturers on the market are actually just LED-backlit displays. As for the difference between the two, I will break it down for you in detail.
Let's talk about LED displays first. The correct interpretation of LED displays should be those using LED displays. LED is lightemitTIngdiode, the abbreviation of light emitting diode. The LED display screen is a matrix composed of many LED light-emitting diodes. It is used to display various information such as text, graphics, images, animations, quotes, videos, and video signals by controlling the display mode of the semiconductor light-emitting diodes.
The correct full name of the LED backlit display is a liquid crystal display using an LED backlit liquid crystal panel. Because the liquid crystal of the LCD itself does not emit light, it must rely on additional light sources to achieve the display function. The traditional LCD panel uses a CCFL backlight module, and a few of the latest LCD panels are now using LED backlight modules. Therefore, the so-called LED backlight display is also a liquid crystal display, but only the backlight part of the liquid crystal panel has undergone certain changes.
The difference is only the word "backlight", one for the LED panel and the other for the LCD panel, the product is absolutely different. In the current consumer market, many manufacturers call LED backlight displays 100%. This scam is countless deceptions in the market.
In addition, although major manufacturers are misleading everyone, indicating that their own is an LED display, in fact, as far as the current technology is concerned, whether the display effect of a real LED display can be stronger than a liquid crystal display is still a big problem.
