1. Different subjects
1. TFT screen: Thin film field effect transistor, which is a type of active matrix liquid crystal display.
2. LED backlight: It is a flat panel display composed of small LED module panels.
3. IPS screen: It is a technology based on TFT, and its essence is still a TFT screen.
2. Different characteristics
1. TFT screen: It can "actively" control each independent pixel on the screen, which can greatly improve the reaction time.
2. LED backlight: It has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation.
3. IPS screen: Both poles are on the same surface, unlike other liquid crystal modes where the electrodes are on the upper and lower sides, arranged three-dimensionally.
3. Different technologies
1. TFT screen: It is an active matrix liquid crystal display. It is technically driven by an "active matrix" method by using thin film technology. The made transistor electrode uses the scanning method to "actively pull" to control the opening and closing of any display point.
2. LED backlight: an electronic display screen composed of LED dot matrix, which changes the screen display content such as text, animation, pictures, and videos by turning on and off red and green lamp beads in time, and is assembled through a modular structure Display controls.
3. IPS screen: The arrangement of liquid crystal molecules has been optimized and adopted a horizontal arrangement. When encountering external pressure, the molecular structure sinks downward slightly, but the overall molecules are still horizontal.
