The difference between Led and lcd and its advantages and disadvantages:

1. LCD is the full name of liquid crystal display Liquid Crystal Display. It mainly has several types of liquid crystal displays such as TFT, UFB, TFD and STN.

LED is the abbreviation of Light Emitting Diode. LED applications can be divided into two categories: one is LED display; the other is LED single tube application, including backlight LED, infrared LED and so on. As far as LED displays are concerned, China's design and production technology levels are basically in line with international standards. 2. LED display Compared with LCD display, LED has advantages in brightness, power consumption, viewing angle and refresh rate. LED technology can be used to make displays that are thinner, brighter, and sharper than LCDs. The power consumption ratio of LED to LCD is about 1:10, and LED is more energy efficient.

3, LED has a higher refresh rate, better performance in video. The LED provides a viewing angle of up to 160° and can display a variety of text, digital, color images and animation information, and can play color video signals such as TV, video, VCD, DVD, etc.

4, LED display single element reaction speed is 1000 times that of LCD liquid crystal screen, can also be taken under strong light, and adapt to low temperature of minus 40 degrees. Simply put, LCDs and LEDs are two different display technologies. LCDs are displays made up of liquid crystals, while LEDs are displays made up of light-emitting diodes.

5. The LED display currently on the market is not a true LED display. It is precisely an LED-backlit LCD display. The LCD panel is still a traditional LCD display.

For liquid crystal displays, the most important key is their LCD panel and backlight type, while the LCD panel on the market generally uses TFT panel, which is the same. The difference between LED and LCD is only that their backlight type is different: LED The backlight and CCFL backlight (also known as fluorescent light) are diode and cold cathode lamps, respectively.

Advantages and disadvantages The LED display is a 5,000-yuan computer configuration sheet consisting of a light-emitting diode arrangement. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, less failure, large viewing angle and long visible distance.
The biggest advantage of LCD compared with traditional CRT is power consumption and volume. For traditional 17-inch CRT, its power consumption is almost 80W or more, while the power consumption of 17-inch LCD is mostly above 40W. Down, LCD has obvious advantages in terms of energy saving.
