1. Concept interpretation
The so-called hard screen means that a layer of transparent resin material with higher hardness is added to the surface of the LCD screen to protect the outer film. The application of this technology was first invented by a Japanese company, and finally upgraded by LG, and gradually formed LG characteristics The IPS hard screen technology is characterized by good stability. When the surface of the LCD splicing screen is gently swiped by hand, water ripples and dark shadows will not appear, which helps to protect the screen.
The so-called soft screen is relative to the hard screen, which means that there is no liquid crystal panel with a protective outer film. The current representative brand is Samsung. The prominent feature of this screen is that when you press it lightly with your finger or swipe it down with your fingernail, there will be a more obvious water ripple phenomenon, but it will disappear immediately and will not interfere with the image quality.
Two, the difference between the two
The fundamental difference between a hard screen and a soft screen is only with or without a film on the screen surface, and it will not and cannot change the intrinsic physical properties of the LCD panel itself, so the image quality still maintains its inherent characteristics. If on the same occasion, using the same signal source, compare the hard-screen and soft-screen LCD TVs, the picture quality is obviously different, then the most critical issue should be the level of the LCD panel and the core configuration of IC drive performance. There is no difference between "hard screen" and "soft screen".
Hard screen and soft screen are easy to distinguish: lightly scratch the screen with your hand, and if there is a more obvious water mark, it is a soft screen; if the water mark is light or even absent, it is a hard screen. Since so far, among the many domestic and foreign standards on the quality of LCD screens that can be referred to, there has been no "soft" and "hard", and there is no other authoritative organization that has commented on the quality of hard and soft screens. . Therefore, it can be said that the hard screen and the soft screen are only the difference in the post-process processing of the LCD splicing screen, and there is no fundamental difference between good and bad. To be more precise, that is to say, the hard screen is nothing more than a protective film on the LCD panel. The LCD TV with a film screen is not necessarily optimal, and the LCD TV with a non-film screen is not. It must be bad.
Regarding the material of the LCD splicing screen, the hard screen and the soft screen are also the physical structure of the liquid crystal, and basically have the same performance. The hard screen with a protective film seems to have better safety, but it still does not exceed the liquid crystal. The screen is a fragile physical defect. Therefore, whether it is a hard-screen or soft-screen LCD splicing screen, it is also afraid of collisions and needs to be carefully protected. What everyone cares about most when buying LCD splicing screens should not be the panel production technology. You should look at the factors that interfere with your use, such as stability, display effect, and repair rate.
