α-Si TFT active matrix liquid crystal display is not an LED display. The essential difference between the two lies in the light-emitting principle and structure: the former uses amorphous silicon thin film transistors (α-Si TFT) to drive the deflection of liquid crystal molecules, and transmits light through a backlight source (such as CCFL or LED) to form an image, which is a passive light-emitting liquid crystal display technology; the latter uses LED (light-emitting diode) self-luminescence to directly form an image, without the need for a liquid crystal layer and a backlight source. In short, α-Si TFT-LCD is a liquid crystal screen, while LED display is a self-luminous screen, and the technical paths are completely different.
