Most owners of mobile electronics necessarily install a screen protector on the screens of their phones, in the form of tempered glass or PET film. This article will let you know whether the screen protector really works, in which cases it helps, and in which cases it does not work.
Dust, dirt, moisture
During operation, the mobile device inevitably gets dirty. Sweaty or insufficiently clean hands leave streaks. There is a high probability of accidentally spilling a few drops of cold or hot drinks. Devices that have not been used for some time are covered with dust.
Protective film and glass equally cope with the problems listed above. Finger stains, dust and stuck drops of spilled drinks are easily removed with a combination of wet and dry wipes. Appropriate cleaning agents are also provided for cleaning tempered glass.
The tempered glass on top of the screen is prone to scratches. Small sand particles, plastic and metal objects gradually scratch the outer surface. With a cursory inspection, the scratches are often not visible, only at a certain angle, sufficient lighting and/or prolonged peering. Therefore, the availability of tempered glass or film will help to eliminate the formation of scratches on the surface of the screen module.
The strength of tempered glass is 4-6 units on the Mohs scale, and the strength of the film is 1-3 units. Therefore, tempered glass is less susceptible to scratches. But the film will be covered with scratches in a few weeks and will require replacement. The only exception is that a hydrogel film with the ability to tighten small scratches. In any case, tempered glass will cope with the impact of abrasive and small scratches better.
Impact when falling
The fall of a mobile device to the floor often ends with chips or cracks on the surface of the screen module. This is facilitated by the mechanical energy gained by falling from a height. The probability of damaging the mobile device with tempered glass is lower, since the additional glass allows you to dissipate all or most of the mechanical energy. The film is useless when the device falls, since it is not able to absorb a sufficient amount of mechanical energy.
Also, the tempered glass screen protector effectively copes with impacts when foreign objects fall. For example, if the smartphone is lying with the screen up on a flat surface, and the dropped network charger falls from above. Falling of light objects usually does not lead to damage to the glass, but large/heavy objects make damaging both the protective and the main glass highly probable.
How does screen protector work?
A plastic film or tempered glass is placed on top of the screen. During use, the screen protector reflects abrasive particles that can cause scratches. It also reflects objects in contact with the screen, which can fall on the screen from a height or pressed in the pocket of the bag. In addition, protective glass can absorb a certain amount of mechanical energy. For example, if the phone falls on the screen protective glass will absorb all or most of the impact, so the tempered glass can break, but the phone screen remains intact.
Does iPad need a screen protector?
If the iPad is actively used and you want to avoid scratches, then it is worth to install a protective cover. If the iPad is used at home, carefully and gently with minimal risk of damage to the screen, then a protective coating is not necessary.
Do anti-glare screen protectors work in sunlight?
Yes, they do. Some films eliminate glare, and some only partially suppress glare. The best effect is with well-known brand protective coatings.
Does the liquid screen protector work?
Certain liquid screen protectors work, but the protective properties are substantially inferior to conventional film or glass. Some liquid screen protectors also provide a high-quality oleophobic effect. Therefore, liquid films work well together with tempered glass.
Can you fix a cracked screen protector?
No, it is better to replace the damaged protective coating with a new one.
Is Zagg a good screen protector?
Yes, the products of this brand are at a good level.
Does the nano screen protector work?
In terms of protective properties, such a protective coating is of little use. If it is necessary to give the screen oleophobic qualities, then it is worth using a liquid protective coating
What is UV screen protector?
This is regular tempered glass or composite glass with a curved or flat shape. A liquid gel is used to fix the glass, which is hardened by UV radiation.
Is UV screen protector good?
Yes. This protective coating stays firmly on the screen and lasts longer than ordinary silicone-based glass.
Does tempered glass ruin your screen?
No, on the contrary, tempered glass prevents the formation of scratches, chips, cracks and can even save your phone screen from breaking. Therefore, after removing the tempered glass the screen looks like a new one.
Do tempered glass screen protectors work against drops?
Under a certain force of impact, the tempered glass will protect the screen. But if the force of the impact is very high, it will not.
Are screen protectors worth it 2021?
Screen protectors are always relevant.
Can I use my phone without a screen protector?
Yes. However, such use will result in fine scratches on the screen after a certain period of use.
Are glass phone protectors worth it?
Tempered glass is the best protection for your screen.
Can screen protectors prevent cracks?
Tempered glass can help prevent scratches and cracks. Normal film or liquid film does a poor job of protecting it.
The article describes in detail whether PET film and tempered glass screen protectors help. The best protection is provided by tempered glass. This accessory eliminates the formation of scratches on top of the screen, absorbs some or all of the mechanical energy when falling and hitting some objects. The film can not be compared with the protective properties of glass, since the coating does not absorb mechanical energy and can withstand contact only with non-sharp objects.
