Let me give you a brief introduction to what is IPS technology. This technology is a panel technology researched and launched by Hitachi in 2001. This technology can also be called "Super TFT" technology.
In the past traditional LCD display screens, many LCD TVs have adopted a wide viewing angle mode. From a technical point of view, this is the PVA and MVA changing the liquid crystal into two switching forms of vertical and bidirectional tilt, so that the liquid crystal molecules can be switched in the vertical and parallel states. The IPS technology introduced by Hitachi is an unprecedented innovative move, which is quite different from the previous technology.
And how is it different from previous LCD screens?
The above also said that traditional liquid crystals are both vertical and tilted, and IPS technology changes the state of the liquid crystal to parallel. That is to say, no matter what the state, the liquid crystal molecules always keep the same as the screen. Only when the power is turned on or in the normal state, the rotation state of the molecules will change slightly.
IPS technology requires certain improvements to the electrodes, because the rotation state of the liquid crystal molecules is the rotation in the plane of the XY axis, but the rotation of the liquid crystal molecules in the traditional PVA and MVA technology belongs to the Z axis rotation, also known as space rotation. . Therefore, in order to adapt to this structure, IPS has the electrodes on the same side, thus forming a plane electric field. But IPS technology also has certain drawbacks, that is, the light efficiency of the liquid crystal is too low. Although the improved technology solves the problem of viewing angle, the light transmittance is too low due to the electric field effect. The response time is also slower. The high level of the current IPS LCD display is: 16.7M colors, its viewing angle is 178 degrees, and the response time is 16ms.
