First, what is the LCD screen?
LCD is a liquid crystal display (English name is LiquidCrystalDisplay), LCD LCD screen mainly has TFT, UFB, TFD, STN and other types of liquid crystal display, and it is impossible to locate the program input point on the dynamic link library.
The LCD screen is commonly used in TFT. TFT (ThinFilmTransistor) refers to a thin film transistor. Each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel, so that high-speed, high-brightness, high-contrast display screen information can be achieved. One of the color display devices is the mainstream display device on laptops and desktops. Compared with STN, TFT has excellent color saturation, reducing power and higher contrast. It is still very clear under the sun, but the disadvantage is that it consumes more power and costs.
Second, what is the LED display?
LED is the abbreviation of LightEmittingDiode. 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. The LED display screen is a 5000 yuan computer configuration sheet of a display device composed of LED arrays. 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.
Third, the difference between LCD and LED
Compared with LCD displays, LED displays have advantages in terms of brightness, power consumption, viewing angle and refresh rate. LED technology can be used to make displays that are thinner, brighter, and sharper than LCDs.
1. The power consumption ratio of LED and LCD is about 110, and LED is more energy efficient.
2. LED has a higher refresh rate and better performance in video.
3, LED provides a viewing angle of up to 160 °, can display a variety of text, digital, color images and animation information, can play TV, video, VCD, DVD and other color video signals.
