Technical advantages of LED

　　The power consumption ratio of LED to LCD is approximately 1:10, and the higher refresh rate allows LED to perform better in video, providing a wide viewing angle of up to 160 °. It can display various text, numbers, color images, and animation information, as well as play color video signals such as TV, video, VCD, DVD, etc. Multiple displays can also be broadcasted online. The individual element reaction speed of organic LED display screens is 1000 times that of LCD LCD screens, which can be taken care of without error under strong light and can adapt to low temperatures of -40 degrees Celsius. By utilizing LED technology, it is possible to manufacture displays that are thinner, brighter, and clearer than LCDs, with broad application prospects.

　　LCD is the full name of liquid crystal display screen: it includes TFT, UFB, TFD, STN and other types of liquid crystal displays.

　　The commonly used laptop LCD screen is TFT. TFT screen is a thin film transistor, also known as ThinFilmTransistor in English. It is an active matrix type liquid crystal display with a special light tube installed on its back, which can actively control each independent pixel on the screen. This is also the origin of the so-called active matrix TFT, which can greatly improve the reaction time, about 80 milliseconds, compared to STN's 200 milliseconds! It also improves the phenomenon of STN flickering (water ripple) blurring, effectively improving the ability to play dynamic images. Compared with STN, TFT has excellent color saturation, restoration ability, and higher contrast. It can still be seen very clearly in the sun, but the disadvantage is that it consumes more power and has a higher cost.

　　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. The resolution of LED is generally low and the price is relatively expensive because of its higher integration.
