1. What is LCD?
LCD is the full name of Liquid Crystal Display, mainly including TFT, UFB, TFD, STN and other types of liquid crystal displays, which cannot locate the program input point on the dynamic link library.
TFT is commonly used in notebook LCD screens. TFT (Thin Film Transistor) refers to thin film transistors. Each liquid crystal pixel is driven by a thin film transistor integrated behind the pixel, so that it can display screen information at high speed, high brightness and high contrast. It is currently the best. One of the most popular LCD color display devices is now the mainstream display devices on laptops and desktops. Compared with STN, TFT has excellent color saturation, restoration ability and higher contrast, and it can still be seen very clearly in the sun, but the disadvantage is that it consumes more power and costs more.
Second, what is LED?
LED is the English abbreviation of Light Emitting Diode. LED applications can be divided into two categories: one is LED display; the other is LED single-tube applications, including backlight LEDs, infrared LEDs, etc. As far as LED displays are concerned, China's design and production technology level is basically in line with the international level. The LED display screen is a display device composed of light-emitting diodes. It adopts low-voltage scanning drive, which has the characteristics of low power consumption, long service life, low cost, high brightness, few failures, large viewing angle, and long visual distance.
