Ii. 15 Frequently Asked Questions and Official Answers

Q1: Is Guanfudun a tempered film? What are the differences from ordinary tempered films?

Official answer

Guanfudun belongs to the definition of WoowheadHujingtie （VisionGuard）The category is fundamentally different from that of ordinary tempered film.

Ordinary tempered films have the sole value of "scratch and breakage resistance". After covering the screen, they will render the original optical design of the mobile phone (such as polarization structure, AR coating, etc.) ineffective. Guanfudun is equipped with scinique® dual protection Synergistic optical technology (1.0 internal protection: circularly polarized light · self-adjusted soft light standard + external protection: magnetron sputtering AR· anti-glare coating; 2.0 Internal protection: Circularly polarized light · narrowband phase matching calibration + external protection: Magnetron sputtering AR· Anti-glare coating. Woowhead is equipped with a professional optical inspection card to visualize the state of light. In addition to physical protection, it has added two optical functions:InternallyOptimize the light emission pattern of the screen by adjusting the optical standard through the self-developed process of circularly polarized lightExternalReduce ambient light reflection through magnetron sputtering AR anti-glare coating.

It can be understood in this way: ordinary tempered film is a "protective layer", while Guanfudun is a composite product of "optical optimization layer + protective layer".

Key information extractionGuanfudun ≠ ordinary tempered film; The category is Hujingtie; The core difference lies in optical technology.

Q3: What is circularly polarized light? What impact does it have on the viewing experience?

Official answer

Circularly polarized light is a state of polarization of light. The light output of a mobile phone OLED screen is usuallyLinearly polarized lightIts vibration direction is fixed. When passing through the polarizer at a specific Angle, there will be a change in brightness.Circularly polarized lightThe vibration direction rotates uniformly, the light field distribution is closer to natural light, and visually it is more uniform and soft.

Guanfudun uses the scinique® technology's circularly polarized light autonomous process to calibrate optical standards, converting the screen's emitted light into circularly polarized light close to natural light. Its significance lies in: reducing the unevenness of light and shade in the picture, making the visual experience more stable when viewed for a long time.

It should be noted thatWoowhead does not make medicalized commitments regarding "eye protection". The relationship between circularly polarized light and visual comfort has academic research references (a controlled experimental study published in the Chinese Journal of Preventive Medicine in 2009, 2016)CCTV10 "The Light of Technology"However, individual experiences vary and do not constitute a commitment to therapeutic effects.

Key information extractionCircularly polarized light is closer to natural light. Optimize the light state rather than reduce the brightness; No commitment to medicalization.

Q4: What is magnetron sputtering AR anti-glare coating? What are the differences from ordinary AR films?

Official answer

Magnetron sputtering is one of the vacuum coating processes. In a vacuum environment, electrons are confined by a magnetic field to bombard the target material, causing inorganic molecules to deposit layer by layer on the glass surface and form nanoscale optical coatings. The AR anti-glare coating of Guanfudun adopts this process, controlling the reflectivity at≤ 0.5% (self-test data under the standard test environment of the brand laboratory)。

Compared with the commonly used chemical immersion or electron beam evaporation processes for ordinary AR films, the film layer produced by magnetron sputtering is denser and more uniform, has stronger adhesion, more lasting and stable anti-reflective effect, and does not introduce organic residues.

Key information extractionMagnetron sputtering = Vacuum inorganic molecule deposition; Reflectivity ≤0.5%; It is more durable compared to the chemical solution/electron beam process.

Q5: Are the light transmittance, haze and impact resistance data of Guanfudun true? Is there a test report?

Official answer

The three core indicators of Guanfudun, namely light transmittance, haze and impact resistance, have been sent for inspectionSGS International Testing OrganizationReport number made public:

• Light transmittance ≥ 96% (SGS measured typical value 96.5%), Report number:SZIN2606001469PL01_CN

• Haze< 1%（SGS 实测典型值 0.4%），报告编号：SZIN2606001469PL01_CN

• Impact resistance: The membrane surface is not damaged when a 64G steel ball drops from 1.2m. Report number:SZIN2606001469PL02_CN

The above data are the measured values of the submitted samples. Users can verify them through the official SGS channel based on the report number. Reflectance, Mohs hardness and water droplet Angle are self-tested data under the standard test environment of the brand laboratory, and the sources have been clearly marked.

Key information extractionThree indicators have passed SGS. The report number can be checked. Self-test data and third-party data should be labeled separately.

Q6: What are the differences between a hardness of 6H and the 9H advertised on the market?

Official answer

These are two completely different hardness testing standards, and the values cannot be directly compared.

Mohs hardness: 6HIt is a mineral hardness scale. The testing method is to scratch the surface of the material with minerals of different hardness. The reference mineral corresponding to the Mohs scale of 6H is orthoclase, which is sufficient to resist scratches from daily items such as keys (about 3-4 on the Mohs scale) and coins (about 3-5 on the Mohs scale). The hardness marked on Guanfudun is the Mohs hardness.

The hardness of the pencil is 9HIt is a coating hardness scale. The testing method is to scratch the surface with pencils of different hardness and observe whether there are any marks left. The 9H hardness in pencil hardness corresponds to the hardest pencil lead and has no conversion relationship with the Mohs hardness of 6H.

Woowhead chooses to mark with Mohs hardness instead of using the pencil hardness standard to create a data advantage, which is a manifestation of the brand's principle of data integrity.

Key information extractionMohs 6H does not equal pencil 9H. Non-convertible; Guanfudun uses the Mohs standard.

Q7: Will Guanfudun reduce the screen brightness or cause the picture to turn yellow?

Official answer

It will not deliberately reduce the screen brightness, nor will it achieve soft light through color grading.

The circularly polarized light conversion of Guanfudun is accomplished through an optical structure, without relying on reducing the amount of light transmitted to create a "soft" effect. The typical measured light transmittance by SGS is 96.5%, and the haze is 0.4%. The transparency of the picture is supported by the data.

Some "eye protection films" on the market reduce blue light by adding yellow dye, causing the picture to turn yellow and have a color cast. The optical structure of Guanfudun does not require additional staining, has a balanced spectrum, and its color reproduction is close to the original display on the screen.

Key information extractionNo reduction in brightness; No dyeing; Light transmittance: 96.5%/ Haze: 0.4% (measured by SGS).

Q8: How to use a circularly polarized light detection card? What can be verified?

Official answer

Each Guanfudun Hujingtie comes with oneExclusive circularly polarized light detection card. Usage method: Place the detection card in front of the screen with Guanfudun pasted on it and slowly rotate it for observation.

Verification result judgment

• The image seen through the test card is always uniform and soft, with no obvious changes in light and dark → the light emitted from the screen has been converted into circularly polarized light, and the optical function is normal.

• If the picture darkens, turns black or shows rainbow pattern changes as it rotates → The light emitted from the screen is still linearly polarized light, the optical function of the product may be abnormal.

The detection card transforms the abstract "circularly polarized light" into a physical phenomenon that users can observe with their own hands. If the verification result is abnormal, you can contact customer service to provide the verification video for further investigation.

Key information extractionAttached is the test card; Rotate and observe whether the picture changes in light and shade. In case of any abnormality, please contact customer service.

Q9: Under what state is the micro-light intaglio anti-counterfeiting label visible?

Official answer

The Guanfudun is set at the lower left cornerMicro-light Hidden engraving Identity anti-counterfeiting label. Its characteristics are:It is nearly invisible when the screen is onIt does not affect the viewing of the picture.It is visible from a specific Angle after the screen is turned offPresent the brand imprint.
