Compared to LCD displays and LED displays, LEDs have more advantages in terms of brightness, power consumption, viewing angle, and refresh rate, and have canceled navigation to this page. With LED technology, displays that are thinner, brighter, and clearer than LCDs can be produced.

1, LED and LCD power consumption ratio is about 1:10, LED is more energy-efficient.

2, LED has a higher refresh rate, in the video has a better performance.

3, LED provides a wide viewing angle of 160 °, you can display a variety of text, numbers, color images and animation information, you can play TV, video, VCD, DVD and other color video signals.

4. The response speed of individual elements of LED display screen is 1000 times that of LCD LCD screens. It can also be viewed under strong light and it can adapt to the low temperature of minus 40 degrees.

Simply put, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystal, and LED is a display screen composed of light-emitting diodes.

Dear friends, now we should understand the difference between LCD and LED! Then we will certainly say that LED is so good, then I must buy LED display! However, the focus of this article will come: Currently on the market said the LED display The screen is not a true LED display. It is exactly a LED-backlit LCD. The LCD panel is still a traditional LCD display. In a sense, this is a lot of fraudulent nature! The reason why the British Advertising Association organized a violation of the country’s advertising law was that its “LEDTV” LCD TVs misled consumers. For liquid crystal displays, the most important key is the type of LCD panel and backlight, and the LCD panel of the display on the market generally uses TFT panels, which is the same. The difference between LED and LCD is only that their backlight types are different: LED Backlights and CCFL backlights (ie, fluorescent lamps) are diodes and cold cathode lamps, respectively.

The difference between LED display and LCD display:

LED backlight: power saving (30%~50% compared to CCFL power saving), high price, high brightness and saturation.

CCFL backlight: Relative to the LED backlight power consumption (or a lot of power than the CRT), cheaper.

There are still real LED TVs in the market (not backlit, they will be active), SONY and Samgsung have, but the panel is currently under 11 inches, and the price is very expensive, such as SONY 11-inch AMOLED TV asking price about rmB18000, It belongs to the high-end market, so it is rarely available in the market. Let's look at the actual picture comparison between LCD and LED. The following two notebook displays: CCFL backlight LCD on the left and LED backlight LCD on the right, red, green, and blue. The comparison is as follows:

As can be seen from the figure, the color difference between the LCD screen and the LED screen is generally not very large under the naked eye. If you just pay for the name of LED, it is not worth the money. It is really not necessary.
