ft LCD display is generally called "active panel" by most liquid crystal displays, and the core technology of "active panel" is thin film transistor, that is, TFT, which has led to people's name for active panel has become TFT, although this name is not appropriate, but it has been like this for a long time. Where is the specific difference, let's take you to understand.
The working method of the TFT LCD is that each liquid crystal pixel on the LCD is driven by a thin-film transistor integrated behind it, that is, TFT. In simple terms, TFT is to configure a semiconductor switching device for each pixel, and each pixel can be directly controlled by dot pulses. And because each node is relatively independent, it can also be controlled continuously.
The full name of IPS screen is (In-Plane Switching, plane switching) IPS technology changes the arrangement of liquid crystal molecules, and adopts horizontal switching technology to speed up the deflection speed of liquid crystal molecules, ensuring that the picture clarity can be super-high when shaken. The strong expressive power eliminates the blurring and water pattern diffusion of the traditional LCD screen when it receives external pressure and shaking. Because the liquid crystal molecules rotate in the plane, the IPS screen has a very good viewing angle performance, and the viewing angle can be close to 180 degrees in four axial directions.
Although the IPS screen technology is very powerful, it is still a technology based on TFT, and the essence is still a TFT screen. No matter how strong the IPS is, after all, it is derived from TFT, so the tft screen and the ips screen are derived from one.
