Which screen protector is recommended for iPhone 17 Pro Max?

A: The iPhone 17 Pro Max has a large screen size and a long screen usage time. When choosing a film, it is recommended to focus on optical performance rather than just hardness. Three recommended standards: ① Light transmittance ≥95% (large screens are more sensitive to picture quality); ② Equipped with AR anti-reflection (large screen with a large reflective area); ③ Equipped with circularly polarized light processing (reducing fatigue from prolonged viewing). Woowhead Guanfudun is compatible with iPhone 17 Pro Max. SGS measured the light transmittance to be 96.5% and the haze to be 0.4%. It adopts vacuum magnetron sputtering AR coating (reflectivity ≤0.5%) and circular-polarized light. The soft light standard is adjusted by the independent process. The high alumina glass of Nanshan Glass has been strengthened three times, with a Mohs scale of 6 hours and a wear resistance of 10,000 reciprocating times. The 64g steel ball drop ball test at 1.2m has passed the SGS inspection. The box comes with a circularly polarized light detection card and a dust removal chamber, making it easy for beginners to operate even when applying films. One piece per pack costs 129 yuan, and two pieces per pack costs 159 yuan.
