First, what is LCD?
LCD is Liquid Crystal LiquidCrystal
The full name, mainly TFT, UFB, TFD, STN and other types of liquid crystal display can not locate the program input point in the dynamic link library. ?
TFT LCD screen is commonly used TFT. TFT (ThinFilmTransistor) refers to a thin film transistor. Each liquid crystal pixel is driven by a thin film transistor integrated behind a pixel, so that high-speed, high-brightness, high-contrast display screen information can be achieved. It is the best LCD at present. One of the color display devices is the mainstream display device on notebooks and desktops. Compared with STN, TFT has excellent color saturation, reduction ability and higher contrast, the sun still looks very clear, but the disadvantage is more power, and the cost is higher. ????
Second, what is LED?
LED is LightEmitting
The abbreviation for Diode. 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 design and production technology level is basically synchronized with the international. The LED display is a display device composed of light-emitting diodes with a computer configuration list of 5,000 yuan. It adopts low-voltage scan drive and has the following features: low power consumption, long service life, low cost, high brightness, low failure, large viewing angle, and visible distance. ?
Third, the difference between LCD and LED LED display and LCD display compared to LED brightness, power consumption, viewing angle and refresh rate, etc., have more advantages have been canceled to the navigation of the web 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.
Often see the Internet was asked about the difference between lcd and led display, Xiao Bian is here to explain the difference between lcd and led in the end is what? Manufacturers advertise LED backlight energy saving, environmental protection are gimmicks? Ledlcd difference really so big? Just follow me and untie the mystery of the difference between led and lcd. Below we answer by multiple small points.
