LCD is the full name of liquid crystal display: it includes TFT, UFB, TFD, STN and other types of liquid crystal displays.
Laptop LCD screens are commonly used TFT. The TFT screen is a thin film transistor, the full English name is (ThinFilmTransistor). It is an active matrix type liquid crystal display. A special light pipe is set on the back of it to actively control each independent pixel on the screen. This is also the origin of the so-called active matrix TFT. , This can greatly improve the response time, which is about 80 milliseconds, while STN is 200 milliseconds! It also improves the blurring phenomenon of STN flickering (water ripples), effectively improving the ability to play dynamic pictures. Compared with STN, TFT It has excellent color saturation, restoration ability and higher contrast. It can still be seen very clearly under the sun, but the disadvantage is that it consumes more power and the cost is higher.
Simply put, LCD and LED are two different display technologies. LCD is a display screen composed of liquid crystals, while LED is a display screen composed of light-emitting diodes. LEDs generally have lower resolution and are more expensive because they are more integrated.
