The hydrogel film is mainly made of a honeycomb-structured TPU material with super toughness, and of course there are other materials such as PVC, PET, and TPH. TPU is a relatively soft material with super stretchability and retractability, which can resist falling, explosion-proof, and have a certain buffering effect on the collision of sharp objects. Minor scratches and bubbles heal themselves within 24 hours. The hydrogel screen protector is uniquely thin and light, which makes it hardly affect the touch performance of the screen. Moreover, the rise of hydrogel film is not long, and it belongs to a new type of film. Due to its soft material, it fully covers the edges of the phone screen, ensuring edge-to-edge protection.
The main material of the tempered glass screen protector is tempered glass. This glass is covered with a multi-layer protective coating. The thickness of this protective layer is 0.1 mm, which can completely cover the original screen surface and prevent scratches by external forces. and wear, also increases shock absorption. The hardness of glass itself is relatively high, so tempered glass screen protectors are generally more resistant to wear and scratches. However, some studies have also proved that the reflection of tempered film may cause certain damage to the user's eyes. Therefore, it is not suitable for use in models with curved screens and under-screen fingerprints.
With the continuous updating of mobile phones, the screen has also changed a lot, and the curved full screen has become a new choice. The half-screen tempered glass screen protector can no longer completely cover the phone, and there is a white edge phenomenon. This is because the edge of the mobile phone is curved, and ordinary tempered glass screen protectors are designed with straight edges, because the material cannot be bent, so it is normal to have white edges on the edges.
