Hydrogel film and toughened film are two common screen protectors, and they have some differences and advantages in material, characteristics and use effect:

Advantages of hydrogel film:

1. Easy to install: hydrogel film adopts the principle of electrostatic adsorption, no need to use glue when installing, easy to operate, will not leave bubbles and residual glue.

2. Full screen coverage: hydrogel film can completely cover the screen, including curved screens and other irregular screen shapes, providing comprehensive screen protection.

3. Self-healing function: Hydrogel film has a certain self-healing ability to repair minor scratches and extend the service life of the screen.

4. HD Transparency: High-quality hydrogel film has a high degree of transparency, which does not affect the screen display and maintains the clarity of the screen.

Advantages of tempered film:

1. High hardness: the hardness of tempered film is usually higher than that of hydrogel film, which can effectively resist scratches and collisions and provide stronger screen protection.

2. Anti-burst and anti-drop: tempered film can absorb impact to a certain extent, mitigating the risk of screen breakage and providing more comprehensive screen protection.

3. Anti-fingerprint and anti-oil stains: Tempered film usually has anti-fingerprint and anti-oil stains function, which can reduce the impact of fingerprints and stains on the screen and keep the screen clean.

4. anti-vibration and anti-pressure: toughened film has a strong anti-vibration and anti-pressure ability, can effectively protect the screen from damage in the accidental collision.

Taken together, the hydrogel film is suitable for those who pursue easy installation, full-screen coverage and self-healing features, while the tempered film is suitable for those who need higher hardness, anti-scratch and anti-explosion and anti-drop features. You can choose the right screen protector for your device according to your personal needs and preferences.
