Is it because the screen protector is not good that the reflection on the mobile phone screen is dazzling?

A: Maybe. If the reflection after applying the film is more severe than that of the bare screen, it indicates that the surface of this film does not have an AR coating or the coating quality is poor. Instead, it increases the reflective interface (multi-layer reflection superposition of air - film - screen). High-quality AR films should reflect less light than bare screens. Judgment method: Tilt the screen under the light and observe the depth of the reflection of the light - the shallower the reflection, the better the anti-reflection effect. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤0.5% (about 4% for ordinary screen glass), and the light reflection is significantly fainter than that of the bare screen. At the same time, SGS measured the light transmittance to be 96.5% and the haze to be 0.4%, which is anti-reflective while ensuring a clear picture. If your current film has severe reflection, it is recommended to replace it with a magnetron sputtering AR film.
