Does Screen Protector Affect the Touching of Phone Screen

As mobile phone become more and more important, mobile phones have become a necessity in our lives. With the development of this trend, most people nowadays will intsall a screen protector on the phone screen, one is to prevent the phone screen from scratch, and the other is to prevent phone screen from being accidentally dropped.

Moreover, cell phone screen protector have evolved into different kinds and offer different functions. But now many people have doubts, will the mobile phone protective film affect the sensitivity of the device?



There have to say, now a mobile phone touch screen technology, most of the current mobile phone in order to pass the screen touch speed, through the sensitivity of the sensing, capacitive screen technology is applied. This technology mainly uses the conductor characteristics of the human body and the interaction of the screen capacitance to perform the sensing operation.

Simply speaking, the human body is equivalent to an electrode. When the finger touches the phone screen, the screen is inductively opposite to the other electrode. The two sides meet to form a capacitor, and then the corresponding controller can accurately position the finger and perform corresponding Touch, to achieve accurate touch sensing.


Moreover, because the sensing speed occurring in this process is very fast and the sensitivity is high, this technology gradually replaces the traditional screen technology and becomes the mainstream technology of the current mobile phone screen application. But he also has a disadvantage, that is, wet water can not be sensed. Because water is also a kind of conductive body, the combined action of the three parties will cause the induction to be not accurately recognized.

Then some people have said that the screen protector is not a conductive material, so there is no influence on the touch of the mobile phone.


Although this is true in theory, in fact, due to the different materials and thickness of the protective film, it has some influence on the sensitivity of the screen. Especially on screen fingerprint recognition, the impact is more obvious. Nowadays, many smart phones use screen fingerprint recognition technology. However, because the mobile phone screen guard is not suitable after the screen protector is applied, or the thickness is too large, the recognition accuracy is reduced, and sometimes the fingerprint recognition is not very sensitive.


Although it is not excluded, there are still imperfections due to technical screen fingerprinting. Now there is a more intuitive way to open the phone settings, enter the developer options, then drop down to find "tap action feedback", open, and then we can slide on the screen, the screen will show a small ball With the movement of the finger, in the case of moving at different speeds, by observing the different moving distance between the ball and the finger, the delay phenomenon of the touch sensing of the mobile phone screen can be seen.

However, many mobile phone films now have less and less impact on mobile phone fingerprint recognition and touch sensitivity. I believe that new technologies will bring better mobile phone experience to users in the future.

What are the Advantages & Disadvantages of Oleophobic Coating

What are the disadvantages of oleophobic coating? What are the advantages of oleophobic coating?
The application of oleophobic coatings (also known as oleophobic layers) is becoming more and more extensive. In addition to the surface of precision instruments, many scenes requiring high cleanliness will also adopt oleophobic coating. Of course, the oleophobic layer is known and contacted by users most of the fingerprint lock screen and mobile phone touch screen. The addition of oleophobic coating has many advantages, but there are also some troublesome shortcomings. Now let me tell you more.


What are the advantages and benefits of oleophobic coating?
1.Keep clean, screen oleophobic coating generally uses nano-materials, using electroplating process, forming a protective film on the screen surface, with hydrophobic and oleophobic functions, oil stains are not easily contaminated, easy to wipe, can effectively keep the screen clean.


2.Enhance the operation feel, the nano-material of the oleophobic layer has a smooth surface, smooth operation, does not increase the friction of the fingers, greatly reduces the obstruction phenomenon, and the touch is better.


3.To ensure touch sensitivity, oil contamination will reduce the sensitivity of fingerprint recognition, finger touch and other operational reactions, affecting the use efficiency, oleophobic layer cleaning ability is the guarantee of sensitivity.


In addition, the oleophobic coating has the characteristics of low process cost, which provides the first conditions for mass production.

Although the application of oleophobic layer is extensive, it is not a perfect material and still has some shortcomings.
1.Poor wear resistance, screen oleophobic layer due to the requirements of the touch experience, generally, the thickness can be neglected, long-term high-intensity use will cause the phenomenon of shedding wear, thus greatly affecting the user experience.

2.The process standards are not uniform, the process requirements of different screen surface oleophobic layer are different, resulting in different quality and experience, and does not meet the technical standards required for production and use.

The abrasion of the oleophobic layer is a headache for many users. After the oleophobic coating on the surface of the mobile phone screen or the smart lock touch screen is worn away, it is recommended to purchase the oleophobic layer to solve the problem, that is, the tempered glass screen protector and nano liquid screen protector, so we can protect our phone screen from any scratched.
