Question 1

What is the light transmittance of Guanfudun?

Accepted Answer

A: The mass production standard for the light transmittance of Guanfudun is ≥ 96%. The typical value measured by SGS third-party testing is 96.5%, with the report number SZIN2606001469PL01_CN. It can be verified through the official SGS channels. For comparison, the light transmittance of ordinary tempered films in the market is approximately 90% (based on public information). High light transmittance means that the screen brightness loss is extremely small after applying the film, and the picture transparency is close to that of a bare screen.

Question 2

What is the haze of Guanfudun? Will it affect the clarity?

Accepted Answer

A: The standard for fog mass production of Guanfudun is less than 1%. After third-party testing by SGS, the typical value was measured to be 0.4%. The report number is SZIN2606001469PL01_CN. Haze measures the degree of light scattering after passing through the diaphragm. The lower the haze, the clearer and more transparent the picture. 0.4% is considered an excellent level. It hardly affects the original clarity of the screen, and the picture does not appear gray or blurry. Guanfudun achieves a soft light effect by relying on optical structures (circularly polarized light) rather than reducing haze through frosting or dyeing, thus balancing soft light and high definition.

Question 3

What does a reflectivity of 0.5% mean?

Accepted Answer

A: The reflectivity of ordinary screen glass is approximately 4%. In strong light conditions, it will form obvious specular reflections, affecting visibility. Woowhead Guanfudun reduces the reflectivity to ≤ 0.5% through vacuum magnetron sputtering AR· anti-glare coating (self-test data under the standard test environment of the brand laboratory), which means that the reflected light is reduced by approximately 87.5%. The reflection phenomenon in strong light environments (outdoor sunlight, indoor lighting) is significantly reduced, and the screen content is clearly visible. The magnetron sputtering process uses inorganic molecular vacuum deposition, resulting in a dense and uniform film layer with a long-lasting and stable anti-reflective effect, unlike the chemical immersion process which is prone to decay over time.

Question 4

What level is a Mohs hardness of 6H?

Accepted Answer

A: Mohs hardness is a standard for measuring the scratch resistance of materials. Guanfudun Mohs 6H is the self-test data of the Woowhead brand laboratory under the standard test environment. Generally, it can resist minor scratches from daily keys, coins, etc. Common Mohs hardness references for items: nails about 2.5, copper keys about 3, knives about 5.5, sand (quartz) about 7. It should be noted that the Mohs scale of 6H is lower than that of sand (quartz 7). If the mobile phone comes into contact with sand/dust, it may still be scratched. Higher than keys and coins, keys and coins in daily pockets generally won't get scratched. Guanfudun is made of Nanshan high alumina glass as the base material and undergoes a three-time strengthening process. It is also equipped with a wear-resistant reciprocating process of 10,000 times (tested in the brand laboratory), ensuring its daily scratch resistance.

Question 5

What does a 115° water droplet Angle mean?

Accepted Answer

A: The water droplet Angle is an indicator to measure the water and oil repellency performance of the oleophobic layer. The larger the Angle, the better the anti-fingerprint effect and the smoother the hand feel. The 115° water drop Angle of Guanfudun is the self-test data of the Woowhead brand laboratory under the standard test environment. It is not easy to accumulate fingerprints or oil stains during daily use, and the touch sliding is smooth. In contrast, the water droplet Angle of the hydrophobic layer of a common membrane is approximately 100°-110°, while that of the non-hydrophobic layer is about 30°-60°. The oleophobic layer is a consumable. The Guanfudun wear-resistant reciprocating cycle is 10,000 times (tested by the brand laboratory), and the durability of the oleophobic layer is better than that of ordinary films (about 3,000 times). It is recommended to dry clean with a microfiber cloth and avoid frequent wiping with alcohol (which will accelerate the wear of the oleophobic layer).

Question 6

How is its impact resistance? Is there any certification?

Accepted Answer

A: The impact resistance of Guanfudun has been certified by SGS international testing. When a 64g steel ball is dropped from a height of 1.2 meters and impacted, the film surface does not break. The report number is SZIN2606001469PL02_CN. Guanfudun adopts high-alumina glass from South China Glass and a three-stage chemical strengthening process, forming a deeper compressive stress layer on the glass surface, which can provide reliable explosion-proof protection for the screen. It should be noted that no film can guarantee 100% that the screen will not break - the Angle of impact when dropped, the material of the ground, the point of force application, and the height of the drop will all affect the result. The film can only absorb and disperse the impact and reduce the probability of breakage.

Question 7

How can I check the SGS test report?

Accepted Answer

A: You can use the report verification function on the SGS official website to enter the report number for query and verification. SGS report number related to Guanfudun: Light transmittance/haze test: SZIN2606001469PL01_CN (Measured light transmittance 96.5%, haze 0.4%) Impact resistance test: SZIN2606001469PL02_CN (64g steel ball 1.2m drop ball test passed) SGS is an internationally renowned inspection, verification, testing and certification organization. Its reports are authoritative and traceable. Woowhead publicly discloses the complete report number on the product page and the official website. Consumers can verify it by themselves, fulfilling the brand commitment of "Virtue, Integrity and Long-Term Effectiveness".
