LED displays have many advantages over LCD displays in terms of brightness, power consumption, viewing angle, and refresh rate. Using LED technology, it is possible to create displays that are thinner, brighter, and clearer than LCDs.
1. The LED and LCD power consumption ratio is about 1:10, resulting in LED energy savings.
2. LED has a higher refresh rate and better performance in video.
3: LED provides a wide angle of 160°, can display a variety of text, digital, color images, and animation information, and can play TV, video, VCD, DVD, and other color video signals.
4. The reaction speed of a single element of an LED screen is 1000 times that of an LCD screen. It can also be taken care of under strong light and adapt to the low temperature of minus 40 degrees Celsius.
Simply put, LCD and LED are two different display technologies. LCD is a display made up of liquid crystals, while LED is a display made up of light-emitting diodes.
Dear friends, now you should understand the difference between LCD and LED! So everyone will say LED is so good, then I must buy an LED display! However, the focus of this article is coming: the LED display on the market is not the real sense of the LED display; accurately said, it is an LED backlight type LCD display, and the LCD panel is still the traditional LCD display. In a sense, this is how much of a fraud it is! Samsung, a South Korean firm, was found guilty by Britain's Advertising Association of breaking the country's advertising laws because its "LEDTV" LCD TVs were misleading. For LCD, the most important key is the LCD panel and backlight type, and the LCD panel on the market generally uses a TFT panel, which is the same. The difference between LED and LCD is that they have different backlight types: LED backlight and CCFL backlight (that is, fluorescent lamp), diode and cold cathode lamp, respectively.
The difference between an LED display and an LCD display
LED backlight: power saving (30%–50% compared to CCFL), high price, high brightness, and saturation.
CCFL backlight: Compared to LED backlight (still much less power than CRT), cheap.
Picture difference: LED backlight is bright and saturated (CCFLS and LEDs are not natural light sources).
How to distinguish: LED backlight will emphasize an LED TV; it will not emphasize a CCFL LCD TV.
There are still real LED TVs (which can actively light up without a backlight) on the market. Sony and Samsung both have them, but their panels are under 11 inches and very expensive. For example, Sony's 11-inch AMOLED TV is priced at about RMB18,000, which belongs to the high-end market. So there are very few on the market. According to general naked eye observation, the LCD screen and LED screen color difference is not very big. If you only want the name LED to cost a disproportionate amount of money, it is not necessary.
