Mainly reflected in the following aspects:
Technical principle: Although TFT (Thin Film Transistor, thin film transistor) screen and LCD (Liquid Crystal Display, liquid crystal display) screen are both based on liquid crystal display technology, their working principles are different.TFT screen is an active matrix liquid crystal display technology. Each pixel is driven by a thin film transistor, which can independently control the light emission of each pixel, thereby presenting richer colors and higher dynamic contrast.The LCD screen controls the transmission of light by changing the arrangement of liquid crystal molecules. It is a passive display technology.

Image quality performance: Because TFT screens have higher response speed and better color saturation, they are generally able to provide better image quality performance.At the same time, LCD screens may be slightly inferior to TFT screens in terms of color expression, but they have advantages in viewing angles and black depth.
Energy consumption and service life: The backlight design of TFT screens makes them consume more energy, but the advancement of modern technology has greatly reduced this shortcoming.In comparison, the backlight design of the LCD screen is simpler, so it has an advantage in energy consumption.In terms of service life, there is almost no difference between the two, and both can maintain stable performance over a long period of time.
