What is the difference between LCD display and LED display?

- Feb 11, 2018 -

LCD is the full name of liquid crystal display LiquidCrystalDisplay, mainly TFT, UFB, TFD, STN and other types of LCD screen can not locate the program input points on the dynamic link library.

Notebook LCD is commonly used TFT. Thin Film Transistors (TFTs) refer to thin film transistors. Each liquid crystal pixel dot is driven by a thin film transistor integrated behind the pixel so as to be able to display high-speed, high-brightness and high-contrast screen information. One of the color display devices is now the mainstream display on laptops and desktops. Compared with the STN, TFT has excellent color saturation, reducing power and higher contrast, the sun still looks very clear, but the disadvantage is more power consumption, and the cost is higher.

LED is the light-emitting diode LightEmittingDiode acronym. LED applications can be divided into two categories: First, LED display; Second, LED single-tube applications, including backlight LED, infrared LED and so on. Now on the LED display, China's basic level of design and production technology with the international community. LED display is composed of light-emitting diodes arranged. It uses low-voltage scan driver, with: less power consumption, long life, low cost, high brightness, less failure, wide viewing angle, visual distance and so on.

LED Displays Compared to LCD monitors, LEDs are more advantageous in terms of brightness, power consumption, viewing angle and refresh rate, etc. The navigation to the web page has been canceled. Using LED technology, you can create thinner, brighter, clearer displays than LCDs.

1, LED and LCD power ratio of about 1: 10, LED more energy.

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

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

4, a single element LED display speed of reaction is 1000 times LCD screen, under the glare can also be taken care not wrong, and to adapt to minus 40 degrees of low temperature.

Simply put, LCD and LED are two different display technologies, LCD is composed of liquid crystal display, and LED is made of light-emitting diode display. However, the current market, said the LED display is not the true sense of the LED display, accurate to say that the LED-backlit LCD display, the LCD panel is still the traditional LCD display.

For the LCD monitor, the most important key is its LCD panel and backlight type, while the LCD monitor on the market generally uses the TFT panel, is the same, the only difference between LED and LCD is their backlight type is different: LED Backlight and CCFL backlight (that is, fluorescent), respectively, diode and cold cathode fluorescent lamp.
