The structure of the LCD panel is actually a liquid crystal sandwiched between two layers of glass plates. As light passes through the liquid crystal, the liquid crystal moves and then assumes an irregular shape. Liquid crystal is actually a substance between the crystal state and the liquid state. It has the characteristics of liquid and crystal at the same time, and has its own unique property. The pixels of the IPS LCD screen are in the shape of fish scales, and there is no water mark when touched. As far as the material of the LCD screen is concerned, both the soft screen and the hard screen have the same physical structure of liquid crystal, and their basic performances are the same.

The liquid crystal will not have the problem of jitter or afterimage, and the display effect will not change. The hardness of the hard screen is not determined by the addition of a resin protective film on the surface of the LCD screen, but by the liquid crystal molecules inside it.

The internal structure of the hard screen and the soft screen is different. The liquid crystal molecules in the hard screen are arranged in a horizontal shape, so when we touch it with our hands, there will be no water ripples, and the image will appear relatively more. Stability, more realistic colors and wider viewing angles. The liquid crystal molecules of the soft screen are vertical, so when we touch it with our hands, there will be water ripples. Compared with the characteristics of the soft screen, the liquid crystal molecules of the hard screen are relatively stable. The response speed is relatively fast, so the dynamic definition is also very good. The soft screen is easily affected by some external factors, such as external pressure and shaking, and its image display will be very unstable. The current car TV — Generally, IPS hard screens are used.

The reason why the hard disk can achieve the above-mentioned remarkable advantages is that the innovation of IPS technology adopts the way of horizontally rotating molecular arrangement. Therefore, compared with the soft-screen liquid crystal technology that is arranged horizontally and vertically, its molecules have stronger reducing power. The panels are also more stable and solid. Not only that, IPS hard screen technology can also greatly extend the viewing angle of up, down, left, and right, close to 180°, and you can watch the picture quality without compromise in any side angle, which is suitable for aerospace, medical, etc. It is a rare tool for fields that require multi-angle observation and display.

In fact, IPS technology is not only applied to professional aspects, in our home appliances is also very common, because of its significant features, so it is widely used in LCD TVs, consumers are also more and more like IPS hard screen according to the market sales situation.
