TFT screen is generally referred to as "active panels" for most liquid crystal displays, and the core technology of "active panels" is thin film transistor, or TFT, which has led people to call active panels TFT. Although such a name is not appropriate, it will be the case for a long time. The difference between TFT screen and IPS screen is as follows:
The working mode of the TFT screen is that each liquid crystal pixel on the liquid crystal display is driven by an integrated thin film transistor, which is TFT. Simply put, TFT is to configure a semiconductor switching device for each pixel, and each pixel can be directly controlled by a dot pulse. And since each node is relatively independent, continuous control can also be performed.
IPS technology changes the arrangement of liquid crystal molecule particles, adopts horizontal conversion technology to speed up the deflection of liquid crystal molecules, guarantees the picture clarity and super expressive power when shaking, and eliminates the external pressure of traditional liquid crystal displays. Blurring and water ripples will appear when shaken. Because the liquid crystal molecules rotate in the plane, the IPS screen is born with a fairly good viewing angle performance, and the four axial directions can achieve a viewing angle close to 180 degrees.
Although the IPS screen technology is very powerful, it is still a technology based on TFT, and the essence is a TFT screen. No matter how strong IPS is, it is derived from TFT after all, so TFT quality and IPS quality are integrated.
