Why is there a rainbow effect in the tempered glass screen protector,how to eliminate rainbow effect

Have you ever seen a rainbow effect in the tempered glass screen protector? Do you know why glass screen protector film have rainbow effect? And how do we eliminate the rainbow effect?


1.What is rainbow effect?
Here the rainbow effect we called is a phenomenon that generally appear arise at the surface of mobile phone screen protector, and it is similar to a rainbow.
glass screen film



2.The harm of rainbow effect
The harm of tempered glass rainbow effect is that it reduces the transmittance of the screen protective film. It also causes the screen protector convey the distortion of the screen color, and affects the our visual experience.




3.So why are there rainbow effect, do you all know the reason?
There are two reasons for the rainbow effect appearing after we installed tempered glass screen film:
First, the screen protection film is made of a multi-layer structure, and when the light is irradiated, the refraction produces a rainbow effect. On the other hand, the "rainbow effect" is created because when the substrate needs to be subjected to a high temperature during the hardening treatment. In the high temperature treatment, the molecular structure of the substrate surface is uneven to cause scattering.




The presence of rainbow effect affects light transparency and visual effects. It is difficult to see the rainbow effect with the naked eye after installation the high quality glass screen film. Rainbow effect is actually the product of hardening treatment. The higher the strength of the hardening treatment, the more difficult it is to control the rainbow effect.


In addition, when the PET substrate is subjected to surface hardened hardening treatment, it is also susceptible to coating equipment and curing materials. If the equipment and materials are improperly selected, it is easy to cause uneven surface coating, which leads to rainbow effect.




4.So, the rainbow effect is so much harmful, how do we eliminate the rainbow effect?
  • Once the temperature rises to 35 degrees, the rainbow effect on the glass screen protector will disappear automatically.
  • The screen protection film is pressed under high temperature environment, when it encounters a sudden low temperature, it will lead to uneven local light transmission, resulting in rainbow effect. When the temperature rises and the overall temperature of the phone screen protector film tends to be the same, the rainbow effect will disappear automatically.
  • If it is a rainbow effect caused by the water on the screen, then we don't have to worry too much, it will naturally return to normal in a few days. If it is caused by external forces, then here we suggest to buy a new screen protector.

What is Noise Cancelling Headphone

Many people think that the noise cancelling headphones are to help us eliminate all the noise except the music you listen, but it is not.

A true noise cancelling earphone is a type of earphone that uses some method to reduce noise. Mainly to meet the better noise shielding in the noisy environment, so as to experience better listening effects, such as in some noisy office, mechanical noise during flight, noise cancelling headphones can isolate most external connections noise (Active noise canceling headphones), so listening to songs will not be interfered by excessive external noise and can enjoy high quality music.


At present, here have two types of noise cancelling headphones in the market. They are Active noise cancelling earphone and passive noise cancelling earphone.

The active noise canceling function is to generate a reverse sound wave equal to the external noise through the noise reduction system, neutralize the noise, and achieve the effect of noise reduction. Active noise cancelling headphones with noise reduction circuit that competes with external noise. Most of them use a large head-mounted design, using the earphone cotton and earphone casing to block the external noise, and to be the first round of sound insulation. At the same time, in order to have sufficient space to install active noise reduction circuits and power supplies.


Passive noise reduction earphone mainly form an enclosed space by surrounding the ears, or use soundproof materials such as silicone earplugs to block external noise. Since the noise is not processed by the noise reduction circuit chip, generally only high frequency noise is blocked, and the noise reduction effect on the low frequency noise is not obvious.

So the effect of the active noise cancelling headphones is more obvious than that of the passive noise cancelling headphones, that’s why most user like the active noise cancelling headset.

And here Shirley recommend two ANC noise cancelling headphones for your reference:

What Affect Your Bluetooth Earphone's Signal

What affect your Bluetooth Earphone's Signal?


Bluetooth wireless communication technology as an open global standard for wireless data and voice communications,the first application was to replace the headphone cable in the field of voice communication.

Until the 4.0 version of the low-power Bluetooth technology is widely used in smart wearable devices and smart home devices, these are gradually upgraded from the original Bluetooth headset era, and now the smart devices for Bluetooth technology applications are more and more popular.

Many friends have encountered such problems when using Bluetooth devices. The signal is intermittent, sometimes strong and sometimes weak, affecting the use of the device. What caused this? Today we have a introduction to the phenomenon of signal difference between Bluetooth receivers.

Bluetooth is a wireless technology standard for exchanging data between fixed and mobile devices over short distances using short-wavelength UHF radio waves in the industrial, scientific and medical radio bands, from 2.400 to 2.485 GHz, and building personal area networks (PANs).
Moreover, Bluetooth is a radio technology that supports short-range communication of devices (maximum transmission distance of 100 meters), which can effectively simplify communication between mobile communication terminal devices, thereby making data transmission more rapid and efficient, it uses a decentralized network structure. As well as fast frequency hopping and short packet technology, it supports point-to-point and point-to-multipoint communication.

The 100 meters mentioned here refers to the maximum transmission distance and is in the condition of no obstruction.From the above, we can speculate that the possible reasons for the bad Bluetooth headset signal are as follows:

1.The Bluetooth Version - The Bluetooth version is an important aspect that affects the connection of Bluetooth headsets. The higher the Bluetooth version, the faster and more stable the signal transmission, and In the process of talking and listening to songs, consumers will encounter fewer signal disconnection and sound jams. At present, Bluetooth headset products on the market generally use Bluetooth version 4.2, and some mid-to-high-end products have been adopted Bluetooth version 5.0.

2.The quality of the headphone, if it is not good, the Bluetooth transmission effect will also affect;



3.Because the human body and clothing are blocked, the Bluetooth transmission is blocked;



4.The Bluetooth earphone battery is about to be empty, and the transmission capacity is degraded.

So in the process of inspection, we can find that these methods can solve the problem of poor signal. The position of the mobile Bluetooth headset, if the signal changes with the position change, the possible reason is "The third point"; if the signal does not change significantly, the earphone is charged, and the effect is tested after full charged; if the above two points are all tested, It is the problem of the transmission capacity of the Bluetooth earphone itself (quality problems and service life problems), which can be replaced or repaired as appropriate.

Of course, there is also a situation where Bluetooth and Wi-Fi signal interference problems may have been encountered. Both of them mainly use the 2.4GHz frequency band. When both are turned on, the data throughput of Bluetooth will drop sharply, and the pairing equipment is difficult. Wi-Fi is intermittently interrupted and the network is limited. At present, there is basically no way to deal with this problem, but you can temporarily solve some problems for you by the following scheme.

Method 1: Connect to a 5GHz wireless network
Now that you know the problem is in the band conflict, consider buying a dual-band (2.4GHz+5GHz) router and connecting to a 5GHz Wi-Fi network. This method can completely solve the interference problem, but cost a lot of money.

Method 2: Replace the Wi-Fi channel
Take the TP-Link router as an example. Log in to the router web management page and find the channel option in Wireless Settings -> Basic Settings and change it to any of 1, 6, and 11. These are 2.4 GHz non-overlapping transmission channels, which are more stable than other channels.

Method 3: Turn on the NIC Bluetooth coexistence function
In the wireless network cards produced in recent years, Bluetooth coexistence is supported. The method is to find Bluetooth Collaboration or Bluetooth Coexistence Mode (name may be different) in the Advanced tab of the network adapter properties, and set it to Enable. Windows will automatically reconnect to Wi-Fi, and the interference with Bluetooth will be alleviated.

Method 4: Keep away from interference sources
Separate the Bluetooth terminal from devices that use the 2.4 GHz band, such as routers, microwave ovens, and cordless phones.

Are Earphones Bad For Our Hearing And Body

Nowadays, headphones & earphones have become a important “friend” for everyone. When we are having a relax, working, playing games, and learning lessons, we all cannot leave without it. And with the launch of wireless Bluetooth earphones, now the earphones are more popular and most people love it.
earphone & headphone

But with the continuous development of headphones, what damages does the headphone cause to our body? Many people say that wearing headphones for a long time will damage hearing. Is this correct? And does the wireless Bluetooth earbuds have radiation problems?

Wearing headphones for a long time can damage your hearing?
headphones

Like other senses, there is a special hearing "receptor" in the ear - the ciliated cells in the cochlea. The reason we can hear the sound is because the ciliated cells are stimulated, and oscillate as the sound vibrates. However, once the cilia swings too much, the sensitivity is reduced and it will damage the hearing in the long run. This damage is gradual, and there is no obvious hearing change at the beginning, so it is always easy to be ignored. Once it is discovered, it is too late.

Relevant medical data also shows that when the volume heard by the human ear exceeds 85 decibels, the longer time can cause hearing fatigue. When the volume is above 110 decibels, it is enough to cause the hair cells of the human ear to die, and in severe cases, it can cause deafness.
wireless headphone headset

So how do we prevent the damage that headphones bring to us?
Expert advice: "Do not wear headphones for more than 1 hour, the intensity should not exceed 2/3 of the maximum volume."

Do you want to use headphones and want to protect your hearing? Then remember these five points:


  • 1.Noisy occasions, do not listen
When the outside noise is large, in order to hear the sound in the earphone, we will increase the volume unconsciously, which will increase the damage.

  • 2. Quiet occasion, low volume listening
In a quiet environment, just set the volume to be clear.

  • 3.Limit the maximum volume
When using the headphones, never turn the volume up to the maximum, preferably no more than 2/3 of the maximum volume.

  • 4.The head design headphone is relatively safe
The headset has a large contact area and a small pressure, which is relatively less irritating to the cochlear ciliated cells and is relatively safer.

  • 5. Avoid listening for a long time
To get rid of the bad habit of using headphones for a long time, WHO recommends that it is safer to not exceed 1 hour each time.
If you feel tinnitus, hearing loss, pain in your ears, and secretions, please go to the ENT department for further treatment as soon as possible.


Does the wireless Bluetooth headset have radiation problems?
What is radiation?
Radiation refers to the phenomenon that part of the electromagnetic energy emitted by the field source propagates away from the field source and then returns to the field source, and the energy spreads out in the form of electromagnetic waves or particles (such as alpha particles, beta particles, etc.). Radiation itself is a neutral word, the name of energy transmission, and light is also a kind of radiation. Everything in nature, as long as the temperature is above zero in absolute temperature, such as the human body, is constantly transmitting heat in the form of electromagnetic waves and particles. This way of transmitting energy can be called radiation.


What is common radiation?
Radiation is divided into solar radiation, electromagnetic radiation and thermal radiation. Common electromagnetic radiation is emitted by electrical appliances. Any consumer has electromagnetic radiation, such as a light bulb. When the electromagnetic wave radiation intensity exceeds the standard amount, it will have a negative effect, causing different diseases of the human body, which may cause harm to human health. This part of the electromagnetic wave radiation exceeding the standard amount is electromagnetic radiation pollution.


What is the radiation value of the Bluetooth headset?
Expert organizations such as the World Health Organization and the IEEE said that the radiation of the Bluetooth headset was not found to be harmful to the human body.

The output power of the Bluetooth product is about 2 milliwatts, which is one-millionth of the power used by the microwave oven. It is one-thousandth of the power of the mobile phone (mobile phone). The radiation of Bluetooth headsets are more safe for the human body, and children and pregnant women can use it with confidence.


Of course, the output power is set to achieve its design purpose. The transmission distance of the Bluetooth headphone is about 10 meters, so only a very low power can be used to achieve the purpose of 10 meters transmission, and because the power of the Bluetooth headset is small, Its penetration ability is also limited.

In fact, the radiation of the Bluetooth earphone is almost negligible. For example, the fluorescent light in your room is larger than the radiation from the Bluetooth headset. Bluetooth headsets have low radiation, which is one of the reasons why many people are optimistic about Bluetooth headsets.

Will screen protector remove oleophobic coating

Will screen protector remove oleophobic coating? Nowadays, many mobile phones have oleophobic layers to reduce the stains on the phone. If we usually use the mobile phone screen protector, will it remove the oleophobic coating? So let us to understand what is the oleophobic layer. What is the function of the oleophobic layer?


What is the oleophobic layer?
We also called oleophobic coating, or hydrophobic coating. As the name suggests, it is a composite coating, which is often coated with nano-silica as a raw material or a nano-scale fluorine-containing material. This coating combines the characteristics of light transmission.

In the field of mobile phones, this coating is mainly used on the screen of mobile phones. It is true that the screen of the mobile phone needs to be very transparent, so it should be as thin as possible and does not affect the display screen of the mobile phone. Its function is to make the phone screen easier to clean and not easy to leave fingerprints and perspiration. At the same time, some mobile phone manufacturers will improve the screen sliding experience when choosing a coating, which makes the screen coating smoother and more natural.

Its principle is not complicated. The contact area of the layer with oil or water is relatively small (compared to a simple glass layer). It originates from a special nanostructure, so the water droplets are like the top of the blade, and it is not easy to attach to the phone screen which it is the so-called "cleaning effect" of the plant leaves.

Phone screen after the coating is worn


As can be seen from the picture, the new mobile phone with oleophobic cpating and the mobile phone that has been almost wiped out by the oleophobic coating for a long time are really different, and the water droplets will spread out.

The misunderstanding of the oleophobic coating
There has been a lot of debate about the oleophobic layer. The focus of the debate is that a heavyweight mobile phone of a heavyweight brand has been exposed without oleophobic layers. In fact, this feature is not required, and there are no regulations or mandatory requirements. Mobile phone manufacturers use oleophobic layers on high-end products to provide a better used feeling.

This configuration is not absolute, not that it must be good. It is true that the oleophobic layer can make the glass perform better, but this performance is not lasting. Because the coating is very thin, it will gradually wear out in daily use. Generally, there will be nothing left in a few months. So the experience is very good at first, and you will find that mobile phones are getting more and more dirty on the screen after few months. In addition to the normal wear and tear of the mobile phone screen, there are many traces of scratches and friction that are invisible to the naked eye, which will cause the oleophobic layer to fall off.
High-Quality Screen Protector

So how to better protect our mobile phone?
First of all, if the original factory mobile phone has no screen protector and comes with an oleophobic layer, then the user can use it with confidence, and the screen can be cleaned well until the oleophobic layer is worn out. If the phone has a screen protector at the factory, it is best not to remove the screen protector directly, unless you are not used to the feel of the screen protector. Nowadays, the high-quality screen protector often has a certain oleophobic effect, and even the coating is attached, to protect our mobile phone screen from scratched.


If you feel that the experience of the mobile phone has been affected, you can also use the popular tempered glass screen protector or high-quality screen protective film. As long as you pay attention to the screen of the mobile phone, it will not be scratched, and it will not be placed with hard objects such as keys.

[NEW] 2 in 1 Stress Reliever & Wireless Earbuds
