With the popularity of smart phones, screen protection has become an indispensable part of mobile phone accessories. Tempered film is popular for its superior protective performance, but there are many types of tempered films on the market, and the quality is uneven. How to choose a tempered film that suits you has become a major problem faced by many users. This article will explain in detail how to choose a tempered film from multiple aspects to help you make a wise choice.

1. Understand the basic knowledge of tempered film
1. What is a tempered film?
Tempered film is a glass film that has been treated with high temperature, with high hardness, high transparency and good impact resistance. Its surface is usually treated with special chemicals to make it scratch-resistant and wear-resistant. Compared with traditional plastic screen protectors, tempered film has more advantages in protecting mobile phone screens.

2. The main functions of tempered film
Anti-scratch: The surface hardness of the tempered film is high, which can effectively prevent scratches in daily use.
Anti-fall: It can reduce the impact of the mobile phone on the screen when it falls to a certain extent and reduce the risk of breakage.
High-definition display: High-quality tempered film has a high light transmittance and will not affect the brightness of the screen.
Anti-reflection: Some tempered films also have anti-reflection functions, which can still clearly display the screen content under strong light.
2. Key factors in selecting tempered films
1. Material and quality
Glass type: When choosing high-quality tempered glass films, you should usually ensure that they are made of high-quality raw materials and avoid using low-grade and inferior glass materials. High-quality tempered films have significant advantages in hardness, transparency and sound quality.
Hardness level: The hardness of tempered films is usually expressed in H (hardness), and common ones are 3H, 6H, 9H, etc. Choosing a tempered film with a hardness of 9H can provide better scratch resistance.
2. Fit
Edge treatment: A high-quality tempered film should have an edge arc design so that it can better fit the mobile phone screen and reduce the risk of bubbles and falling off. In addition, the rounded edge treatment can also improve the touch experience and avoid damage to fingers due to sharp edges.
Size and compatibility: Make sure that the selected tempered film matches your mobile phone model exactly to avoid incomplete screen protection due to size mismatch. Pay attention to whether the holes and openings of the tempered film are accurate to facilitate the operation of the camera, sensors and other functions.
3. Transmittance and display quality
Transmittance: When purchasing, pay attention to the transmittance of the tempered film. The transmittance of a high-quality tempered film should reach 97%~99% or more to ensure the clarity and color reproduction of the screen display. Too low transmittance will affect the visual experience.
Anti-reflective function: If you often use your phone in the sun, you can consider choosing a tempered film with an anti-reflective coating, which can reduce the interference of external light on the screen.
4. Oil resistance and anti-fingerprint
Coating treatment: The surface of high-quality tempered films usually adds anti-oil and anti-fingerprint coatings, which can effectively reduce the adhesion of fingerprints and oil stains and keep the screen clean and tidy. Choosing a film with this type of coating can significantly improve the convenience of daily use.
III. Brand and price
1. Choose a well-known brand
When choosing a tempered film, it is recommended to choose a well-known brand. Big brands usually provide quality assurance and come with after-sales service. Compared with small brands, products from well-known brands have more advantages in materials, craftsmanship and performance.

2. Price considerations
The price of tempered film is usually related to the material, craftsmanship and brand. Although high-priced products are not necessarily the best choice, too low a price often means poor quality. Therefore, when choosing, you should consider the cost-effectiveness comprehensively to avoid losing the big picture for the small.

IV. Installation and use
1. Installation method
Self-installation and professional installation are the two main options. When installing by yourself, pay attention to cleaning the screen to avoid dust and bubbles. If you choose professional installation, you can save a lot of trouble, but you may need to pay extra fees.

2. Usage suggestions
After the tempered film is installed, you should avoid bending the phone screen with force in a short time, and try to avoid heavy objects on the phone to avoid affecting the tempered film. In addition, maintain certain usage habits, such as regular cleaning, to keep it in the best condition.

V. Summary
Purchasing a tempered film is an important step in protecting the phone screen. Choosing a suitable tempered film can not only increase the service life of the phone, but also improve the user experience. Considering the material, adaptability, light transmittance, anti-fingerprint ability, brand and price of the tempered film, you can find the product that best suits your needs.

In the market, high-quality tempered films usually have better performance and user experience, but you must also be vigilant to avoid being affected by bad products on the market. I hope the above suggestions can help you make better decisions when choosing a tempered film, protect the safety of your mobile phone screen, and enjoy a more secure smart life.
