Question 1

What is Hujingtie? What's the difference from tempered film?

Accepted Answer

A: Hujingtie (VisionGuard) is a screen protection category innovatively proposed and continuously developed by Woowhead. It upgrades screen protection from a single physical scratch prevention to a multi-dimensional visual protection of "visual optimization + picture quality protection + hardware protection". Ordinary tempered films focus more on physical scratch and drop resistance, and pay limited attention to the optimization of screen light. Hujingtie, on this basis, is equipped with scinique® Dual Protection Synergist 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. It optimizes the internal light of the screen through circularly polarized light and self-adjusted soft light standards. It weakens the reflection of the external environment through magnetron sputtering AR· anti-glare coating. Achieve five core experiences: soft light visual optimization, anti-glare clarity, high definition, wear resistance and impact resistance. The phrase "protective view" has two meanings: the view outside the window (protected by AR anti-glare coating to reduce external reflection), and the view in the heart (protected by circularly polarized light and self-adjusted soft light standards to create a natural and peaceful visual experience).

Question 2

What are the differences between Hujingtie, tempered film, water condensation film and green light film?

Accepted Answer

A: These are different types of screen protectors. The core differences are as follows: Tempered film: Made of glass as the base material, it focuses on physical protection against scratches and drops. The optical performance is subject to the actual performance of each brand. Water condensation film: Made of flexible materials (such as TPU, etc.), it is well adapted to curved screens, but its protective performance is relatively weak. Its light transmittance and hand feel are not as good as those of glass film. Green light film/anti-blue light film: By dyeing and filtering out some blue light, the drawback is that the screen is prone to color deviation and yellowing, and the brightness is reduced. Moreover, the "eye protection" lacks sufficient scientific basis. Hujingtie: Woowhead defines a new category, equipped with scinique® 2.0 dual-protection collaborative optical technology (internal protection: circulally polarized light · narrowband phase matching adjustment + external protection:) Magnetron sputtering AR· Anti-glare coating, Woowhead is equipped with a professional optical inspection card to visualize the state of light, circularly polarized light · self-adjusted soft light standard + magnetron sputtering AR· anti-glare coating, combining physical protection and optical visual optimization, no staining, no color deviation, and no reduction in brightness

Question 3

What technology is scinique®?

Accepted Answer

A: scinique® is a screen visual protection technology independently developed by Woowhead. Its pronunciation implies a skin-like fit to the screen, endowing it with new optical performance. The name is composed of roots: Sci (Science/Optics) + ni (Innovation, New) + que (Unique/Quality). The core technology lies in the "internal and external dual protection synergy" mechanism: Internal protection: Circularly polarized light · self-adjusted soft light standard - converting the polarized light emitted by the screen into circularly polarized light close to natural light, optimizing the light texture, and reducing reflection and glare stimulation. External protection: Magnetron sputtering AR· Anti-glare Coating - Nano-scale optical coating is formed by vacuum magnetron sputtering process. The destructive interference of light is utilized to reduce the reflection of ambient light, with a reflectivity of ≤ 0.5%. Technical slogan: Dual Protection, Real Comfort. The detail page expresses: One gentle and one clear, both internal and external protection.

Question 4

What is the principle of circularly polarized light technology? What help does it offer to the viewing experience?

Accepted Answer

A: OLED screens emit linearly polarized light. The vibration direction of the light is fixed and unevenly distributed, making the visual adaptation burden more obvious when viewed for a long time. scinique® technology converts linearly polarized light into circularly polarized light close to natural light through an optical phase delay structure (1/4λ wave plate), making the light transition more uniform and soft. The soft light standard has three pillars: Light state transformation: converting polarized light into circular polarized light, optimizing the texture of light, and not deliberately reducing the original brightness of the screen. All-field viewing experience: Natural transition of the picture when viewing from multiple angles, reducing dark corners and color patterns. Color fidelity: achieving soft light effects through optical structures without additional coloring, and color reproduction. Natural science background: A study titled "The Impact of Circularly Polarized Light LCD TVS on Visual Fatigue" published in the Chinese Journal of Preventive Medicine in 2009 showed that the subjects who watched circularly polarized light images had a smaller temporary decline in vision and no significant increase in blinking frequency (an increase in blinking frequency is one of the objective indicators of visual burden). In 2016, the CCTV10 program "Light of Science and Technology" also verified through experiments the characteristic that circularly polarized light always remains uniform and soft. This is a physical optimization at the optical level, which does not rely on staining, does not cause color cast, and does not reduce the screen brightness.

Question 5

How to verify that circularly polarized light is true?

Accepted Answer

A: Each Woowhead Guanfudun comes with a dedicated circularly polarized light detection card. Verification method: After applying the film, light up the screen to display a white image. Place the detection card in front of the screen and rotate it slowly for observation. True circular polarized light: During rotation, the picture remains uniform and soft, with no obvious changes in light and shade. Ordinary linear polarized light: When rotated to a specific Angle, changes in light and shade may occur, accompanied by uneven brightness or local color anomalies. Thus, the invisible optical technology is transformed into a fact that can be verified by hand. The observation differences between the two technologies: scinique® 1.0 Dual protection Synergistic optical technology (internal protection: circularly polarized light · self-adjusted soft light standard; external protection: magnetron sputtering AR· anti-glare coating) ensures uniform and soft rotating observation images. scinique® 2.0 Dual-protection Synergistic optical technology (internal protection: circularly polarized light · narrowband phase matching calibration; external protection: magnetron sputtering AR· anti-glare coating) presents an orange-yellow soft light effect at specific angles on circularly polarized screens (such as apples), providing a more gentle viewing experience. Note: During the detection, the screen should display a white image and the brightness should be adjusted to medium or above. The test card is a polarizer. When not in use, put it back in the package for storage to avoid scratches.

Question 6

What are the differences between magnetron sputtering AR coating and ordinary AR film?

Accepted Answer

A: AR film, also known as Anti-Reflection film, works on the principle of reducing reflectivity by utilizing the destructive interference of light. However, the effects vary significantly depending on different processing techniques. Process type Reflectance (approximately) Process characteristics: Ordinary screen glass 4.0% No AR coating solution immersion process 3.0% Low cost, limited effect, may decay over time electron beam evaporation process 2.0% Mid-range process, medium effect Guanfudun magnetron sputtering process ≤ 0.5% nano-scale inorganic molecule deposition in vacuum environment The film layer is dense and uniform, and the effect is long-lasting and stable. Woowhead Guanfudun adopts vacuum magnetron sputtering AR· anti-glare coating, with a reflectivity of ≤ 0.5% (self-test data under the brand's laboratory standard test environment), which is about one-eighth of that of ordinary screen glass. It can significantly improve visibility under both indoor lighting and outdoor sunlight.

Question 7

What are the differences between blue light protection and circularly polarized light eye protection?

Accepted Answer

A: The technical routes of the two are completely different: Anti-blue light film: It filters out part of the blue light (mainly in the 415-455nm band) through yellow dye. The disadvantage is that the screen is prone to color deviation and yellowing, and the brightness is reduced. Moreover, the blue light output of the mobile phone screen is already within a safe range, and the actual eye protection effect is limited. Circularly polarized light technology: Woowhead Hujingtie optimizes the light form through optical structure, converting linearly polarized light into circularly polarized light close to natural light, improving the eye experience during long-term screen use, without color bias, reduced brightness, or sacrificing picture quality. It adopts a circularly polarized light route and achieves a soft light effect without dyeing. If blue light filtering is indeed necessary, it is recommended to use the system's built-in night view/original color display mode (the software can adjust the color temperature without losing the picture quality), rather than the dyed blue light film.

Question 9

Is it normal for the scinique® 2.0 dual-protection Synergistic optical technology detection card to show an orange-yellow color at a specific Angle?

Accepted Answer

It's normal and does not affect daily use. The orange-yellow soft light that appears when the Guanfudun Qu comes with a circularly polarized light detection card and is rotated to a specific Angle is a verifiable technical manifestation of the phase alignment of the double-layer circularly polarized structure of the scinique® 2.0 dual-protection synergist optical technology - an objective optical feature, not a discoloration of the coating or quality abnormality. Compared with the scinique® 1.0 dual-protection collaborative optical technology, the scinique® 2.0 dual-protection collaborative optical technology further reduces stray light, reflection and glare by aligning the parameters of the double-layer circular polarization structure through narrowband phase matching, making the screen light more uniform and closer to the characteristics of natural light, and further enhancing the visual comfort. There is basically no color cast perception in daily naked-eye use.

Question 10

What is the core technology of Woowhead?

Accepted Answer

A: The core technology of Woowhead is the self-developed 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. It is composed of "circularly polarized light · self-adjusted soft light standard" (internal protection) and "magnetron sputtering AR· Anti-glare Coating" (external protection) working together.
