Hard screen (IPS) refers to: the pixels of the screen body are full-pixel fish scales, with the direction facing left, commonly known as "people". At present, the representative manufacturers who adopt hard screens are LGD, IPSα and other brands; The reason why the hard screen is hard (there is no water mark to the touch) is not because the resin protective film is stuck outside the LCD screen, but because of the molecular structure of the LCD screen. As far as the material of LCD screen is concerned, soft screen and hard screen are also the physical structure of LCD screen, and their basic properties are the same.
The hard screen adopts horizontally arranged liquid crystal molecular structure. When subjected to external pressure, the molecules of the hard screen recover quickly, and when touched, they can basically remain the same. Whether it is a hard screen or a soft screen LCD TV, it will still not surpass the fragile physical characteristics of the LCD screen, and it is also afraid of collision and needs careful protection. As long as the user is careful not to be hit by gravity or scratched by sharp objects, the screen will not be damaged. As for soft screen and hard screen, it is more promoted by commercial speculation and manufacturers. There is no so-called "soft" or "hard" in the quality standards of LCD screens at home and abroad, and there is no authoritative comment on the advantages and disadvantages of hard screens and soft screens. Therefore, it can be said that hard screen and soft screen are only the differences in the later process of LCD panel, and there is no fundamental difference between good and bad.
