With the widespread use of touch-screen mobile phones, mobile phone screen protection films are increasingly favored by consumers. Due to the lack of corresponding product standards, consumers can hardly select and purchase mobile phone screen protection. The key points of the screen protection film quality and the detection method give some suggestions, and hope to have a certain reference effect on the quality standard of mobile phone screen protection film.
The mobile phone screen protection film refers to a protective film that can be pasted on the screen of a mobile phone to prevent the screen of the mobile phone from being scratched or broken, and its material has been originally made of PC (polycarbonate), PVC (polyvinyl chloride), PET (poly pairs Ethylene terephthalate), AR material AR is a synthetic material, generally divided into three layers, silica gel for the adsorption layer, PET for the middle layer, the outer layer is a special treatment layer. Special treatment layer is generally divided into two, AG Treatment layer and HC treatment layer, AG is anti-glare treatment, matte type protective film is the use of this treatment. HC is a hardness treatment, is a highly transparent protective film used in the treatment. This screen protection film is characterized by The screen is not reflective, high transmittance (over 95%), anti-friction and strong scratch resistance.
1. Abrasion resistance
No matter what kind of mobile phone screen protection film (anti-glare film, 3D film, mirror film, diamond film, privacy film), the main purpose of the consumer to prevent the screen is scratched or cracked by a hard object, so the mobile phone screen protection film The abrasion resistance should reach a certain standard. When the screen protection film is relatively soft, the wear resistance is poor, scratches are easily generated when rubbing against the hard material, and the screen cannot be broken due to no protection. When the abrasion resistance is good , screen protection film texture is hard, easy to use during the rainbow pattern, affecting the use of mobile phones.
Visible light transmittance
Light through the mobile phone screen protection film will have a certain degree of attenuation, and mobile phone screen protection film absorption of light, reflection and scattering determines the degree of light attenuation, the more light attenuation, the smaller the visible light transmittance, the darker the phone screen , The greater the eye damage, the visible light transmittance of the mobile phone screen protection film is less than 80%, the continuous viewing of the mobile phone is prone to visual fatigue, endangering the eye health. When the visible light ratio of the mobile phone screen protection film is greater than 92%, the outdoor viewing in the sun is strong. When you're on the phone, you won't see the subtitles clearly.
3. Oil resistance
How to prevent the penetration of oily substances into the screen during the use of the mobile phone is a big problem. Once the oily substance penetrates into the screen of the mobile phone, the mobile phone will become unresponsive and will seriously affect the use. The excellent mobile phone screen protection film will not even drop oil droplets. Spread out, it will not penetrate the protective film into the phone, can play a very good protection.
4. Impact peeling (for tempered film only)
Tempered film is a mobile phone screen protection film made of tempered glass, which can effectively absorb impact energy when impacted by external force, prevent external force from directly contacting with the screen, thereby preventing the screen of the mobile phone from cracking. The tempered film with good quality is cracked. After only cracks appear, there will be no debris spatter injuries, and the poor quality of the tempered film will be broken when it is broken by external forces. It is easy to hurt people. The quality of the tempered film directly affects the consumers.
5. Fitting degree
The protective film for the mobile phone has been bought, and the sticking is actually a very particular issue. A good film is always easy to put on. Tempered glass film filming process can be completely unassuming, unlike ordinary mobile phone protection film, it requires a certain skill to paste. A good piece of tempered glass film, after tearing off the protective sticker, is placed directly on the mobile phone and gently presses a point, so that you can completely fit yourself up and leave no bubbles. And it's very tight and very tight, if it doesn't feel perfect, a tempered glass film can be pasted repeatedly to guide you to be satisfied. If the quality is poor, there will be problems with air bubbles with low adhesion.
Through the above features, how to identify the pros and cons of mobile phone screen protection film, I believe you already have a few.
