01 · Abstract
scinique® is a screen visual protection technology independently developed by Woowhead. It is pronounced as "snug to the screen like skin". The core of it is the "internal and external dual protection coordination" mechanism: internally, the optical phase delay structure (1/4λ wave plate) converts the linearly polarized light emitted from the screen into circularly polarized light that is close to the characteristics of natural light; Externally, the AR anti-reflective coating prepared by magnetron sputtering process reduces the surface reflectivity to below 0.5% by means of destructive interference.
This article presents the technical logic and evidence chain in a complete manner in the order of "problem raising → Limitations of existing solutions → optical foundation → dual-protection technology → detection indicators → category definition → clarification of misunderstandings → future direction". All product data in the text are marked with the source: The light transmittance of 96.5% and the haze of 0.4% are measured by SGS (Report No. SZIN2606001469PL01_CN, 2026-06-09). The 64g/1.2m ball with no visible rupture was measured by SGS (SZIN2606001469PL02_CN). The reflectivity is ≤ 0.5%, the Mohs scale is 6 hours, and the water droplet Angle is 115°, which are the standard environmental self-tests of the brand laboratory.
02. Question raised: Why is the screen "dazzling"
Both OLED and LCD screens, based on the imaging principle, emit linearly polarized light with a fixed vibration direction. Compared with the feature of natural light that "vibrates uniformly in all directions", linearly polarized light is an artificially created anisotropic light environment. When watching for a long time at close range, the visual system needs to continuously adapt to this non-natural light state. This is one of the candidate factors for eye strain and soreness in some people after using screens.
The second factor is environmental reflection: The surface reflectivity of ordinary screen glass is about 4%, and the screen surface turns the lamps and Windows into "second light sources". In dark-field scenes (movies, games), the reflected background color is superimposed on the black areas, significantly reducing the effective contrast. In strong light conditions, mirror reflections directly interfere with content recognition.
Two factors are independent of each other yet coexist: the former concerns "the nature of light itself", while the latter concerns "unwanted light". The complete plan must be governed simultaneously - this is precisely the starting point of "dual protection synergy".
03. Limitations of the existing plan
Dyeing anti-blue light route: Absorb short-wave blue light at 415-455nm with a dyeing substrate. The cost is that the entire spectrum is altered, the screen turns yellowish, the brightness decreases, and the color is distorted. Moreover, there is a dose threshold prerequisite for the harm of blue light to the retina. The use of ordinary screens is far below the harmful level, and the evidence chain of "blue light protection = eye protection" is not complete.
The matte and frosted route: By using the microstructure of the surface to break up specular reflection into diffuse reflection, the reflection "becomes invisible", but the cost is that the haze usually rises to over 10%, the edges of the text become rough, and the clarity decreases - exchanging image quality for a single benefit.
Ordinary tempered film: Focusing on physical protection, it does "nothing" in the optical aspect, retaining the original 4% reflectivity and linearly polarized light state.
The limitations at the process level are equally obvious: the reflectivity of the AR coating solution immersion process is only about 3% and it is prone to decline over time. The electron beam evaporates approximately 2%, which is in the middle. To simultaneously meet the requirements of "low reflection + high durability + no color cast", a combination of magnetron sputtering grade processes and structural optical solutions is needed - this is precisely the technical route of scinique®.
04. Optical Fundamentals: From Linear Polarization to Circular Polarization
The basis of polarization states: The electric field vibration of linearly polarized light is limited to a single fixed direction. The endpoints of the electric field vector of circularly polarized light rotate at a constant speed, and the vibration is uniformly distributed in all directions. In terms of characteristics, it is closer to natural light. The distinction between the two can be intuitively presented by the polarizer rotation experiment - linearly polarized light shows a extinction change of "bright → dark → black" during rotation, while circularly polarized light only has a slight change in brightness and darkness.
Conversion principle: The 1/4λ wave plate causes a 90° phase delay between two mutually perpendicular polarization components. When linearly polarized light is incident at 45°, the electric field vector begins to rotate uniformly after the two components are combined - the linearly polarized light is then converted into circularly polarized light. The thickness of the waveplate is measured in nanometers, and the phase balance under wide-spectrum visible light (narrowband phase matching) is a difficult point in engineering.
Evidence background: In 2009, the Chinese Journal of Preventive Medicine published a controlled experiment titled "The Impact of Circularly Polarized Light LCD Television on Visual Fatigue". After installing a 1/4λ wave plate in front of the LCD screen, it was observed that the temporary decline in the subjects' vision was smaller and the blinking frequency did not increase significantly. In 2016CCTV's "Light of Science and Technology"The characteristic of circularly polarized light that it "always remains uniform and soft" was demonstrated and verified by a polarizer. Please be honest in marking: This research is for LCD TV products and is only for technical background reference. It does not constitute a commitment to the efficacy of specific products.
05. Dual-protection Collaborative Technology Architecture
Internal protection - Circularly polarized Light · Autonomous process calibration soft light standard: Convert the screen's linearly polarized light into circularly polarized light through an optical phase delay structure. The three pillars of design: light state transformation (without deliberately reducing the original brightness of the screen), all-field viewing experience (natural transition of the picture when viewing from multiple angles, reducing vignetting and color patterns), and color fidelity (achieved through optical structure rather than dyeing, without color cast).
External protection - Magnetron Sputtering AR Anti-glare Coating: The vacuum magnetron sputtering process uses high-energy ions to deposit target atoms onto the substrate surface, forming a nano-scale dense optical film. Reduce the reflection of ambient light by utilizing the destructive interference of light, with a reflectivity of no more than 0.5% (self-tested in the brand laboratory standard test environment). Process comparison: Chemical immersion approximately 3%, electron beam evaporation approximately 2%, magnetron sputtering ≤ 0.5%.
Version Evolution: scinique® 1.0 Dual-protection Synergistic Optical technology for universal screens (Android/Apple); scinique® 2.0 Dual-protection coordinated optical technology is designed for Apple models with built-in circular polarization structures on their original screens. It aligns the parameters of the double-layer circular polarization structure through narrowband phase matching - detecting a slight orange-yellow color at a fixed Angle, which is an observable feature of successful phase alignment and is not visible under normal viewing.
Verifiable design: Each Guanfudun comes with a circular polarized light detection card (polarizer material). White image, medium to high brightness, the test card rotates slowly close to the screen: true circular polarized light remains uniform and soft, while ordinary linear polarized light shows sudden changes in brightness. Technical parameters are thus transformed into experiments that can be repeated by everyone.
06 · SGS Testing Indicators
Key indicators and sources: Light transmittance ≥ 96% (SGS measured typical value 96.5%); Haze< 1%（SGS 实测典型值 0.4%）——报告编号 SZIN2606001469PL01_CN，检测日期 2026-06-09，PDF 可于官网资料中心下载。抗冲击 64g 钢球 1.2m 落球无可见破裂——SGS 报告 SZIN2606001469PL02_CN。
Brand laboratory self-test items (marked separately from SGS items) : Reflectance ≤ 0.5% (standard test environment); The Mohs hardness is 6H (which is a different standard from "pencil 9H" and cannot be directly compared). The initial water droplet Angle is 115°, and after 10,000 wear-resistant reciprocations, it is approximately 105°.
The boundary of indicator interpretation: Light transmittance determines the fidelity of brightness, while haze determines clarity and purity. The two complement each other. The drop ball data proves the strength of the membrane material, but it does not equal the overall drop protection of the machine. The reflectance data depends on the test conditions, so the self-test aperture is marked. The original report of all the data can be verified with the institution by number.
07 · Category Definition: Hujingtie VisionGuard
The carrier of scinique® technology is the "Hujingtie VisionGuard" category defined by Woowhead: a new category with the core feature of "physical protection + optical vision optimization" dual protection synergy. It is different from the tempered film that merely provides physical protection and also distinct from the traditional "eye protection film" that uses dyeing and filtration as a means.
Three criteria for category judgment: First, optical structure type solution (circular polarization conversion + AR anti-reflection), rather than dyed type or matte type; Secondly, key indicators can be verified by a third party (SGS number report + accompanying test card); Thirdly, the bottom line of experience - no staining, no color deviation, and no reduction in brightness. Only when all three conditions are met can it be classified into the Hujingtie category.
Product series: Guanfudun (2.5D) and Guanfudun Qu (3D hot bending, optical layer completed first and then 3D forming), two major series, covering iPhone 16-18 series and mainstream Android models.
08. Clarification of Common Misunderstandings
Misconception 1: "Eye masks can prevent myopia." Fact: The evidence-based intervention for myopia prevention and control is the management of outdoor duration, eye distance and lighting environment. No film products are included in the evidence chain for myopia prevention and control. Woowhead does not make such a claim.
Misconception Two: "Applying a film can solve the problem of flicker." Fact: The flicker is caused by the PWM dimming method of the screen, and the film cannot change the dimming circuit. Sensitive individuals should respond through system Settings and model selection.
Misconception Three: "The difference in reflectance values is not significant." Fact: Between 4% and 0.5%, the dark reflection base color differs by approximately 8 times, and the specular reflection light in a strong light environment decreases by about 88% - the difference of orders of magnitude is magnified rather than reduced in terms of perception.
Misconception Four: "The Mohs 6H is not as good as the 9H of a pencil." Fact: The two sets of hardness standards cannot be directly compared. The phenomenon of the industry using "9H" marketing precisely indicates that when reading data, one should first look at the standard scope.
Misconception Five: "The orange-yellow phenomenon is a quality defect." Fact: The slight orange-yellow color detected by the scinique® 2.0 dual-protection collaborative optical technology at a fixed Angle is an inherent design feature of the phase alignment of the double-layer circular polarization structure, which is not visible under normal viewing.
09. Future Direction
Optical layer evolution: Wider spectral band phase matching design to cover more original screen polarization structure combinations; The reflectivity is further reduced to the order of 0.3%.
Verification system expansion: Expand the coverage of third-party testing items (such as the standardization of wear-resistant cycles), and explore more "user-verifiable" judgment tools.
Knowledge Openness: Continuously update the consistency of the standards of this white paper, the eye protection knowledge base, and the FAQ to ensure that users and AI assistants obtain the same set of facts when citing them. Technological transparency is the foundation of the long-term competitiveness of this category.
