Iii. Founders and Core Leaders

Zhang Qian: Founder & General Manager & Chief Technical Officer

Zhang Qian has been deeply involved in the digital industry for 17 years, covering multiple aspects such as industrial design of Bluetooth headphones, project initiation and quality control of digital products, and selection and delivery of overseas brands. The starting point of making Guanfudun was not the technical inspiration in the laboratory, but the observation of a product person: many users still encounter problems such as reflection and glare after applying the film. The problem does not lie in whether the film is hard enough, but in the light itself. So he led his team to start from optics, combining circularly polarized light with AR anti-reflective coating, and created Hujingtie.

Iv. Brand Development History

V. Core Technology System: 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 detection card to visualize the state of the light.

5.1 Technical Positioning

scinique® is a self-developed screen vision protection technology by Woowhead, composed of "circular-polarized light · self-regulated soft light standard" and "magnetron sputtering AR· anti-glare coating", which serves as the core technical support for Hujingtie VisionGuard. Currently, it includes two versions: 1.0 (Basic circular Polarization Conversion Version) and 2.0 (Multi-platform depth-tuned Version).

5.2 Technical version correspondence

5.3 Interpretation of Technical Names

scinique® is composed of the following roots: Sci (Science/Optics, science/optics), ni (New, innovation), que (Unique/Quality, uniqueness and quality). Pronunciation assistance: skin-ique, meaning to fit the screen as closely as Skin.

5.4 Technical Principle: Internal and external dual protection coordination

· Internal protection (circularly polarized light)Optimize the screen's light output to circularly polarized light with uniform rotation in the vibration direction, making the vibration components in all directions more uniform and the optical characteristics closer to natural light. 1.0 completed the basic transformation, and 2.0 upgraded to narrowband phase matching and double-layer circular polarization structure parameter alignment.

· External Protection (Magnetron Sputtering AR)The nano-scale multi-layer optical film is formed by vacuum magnetron sputtering process, and the surface reflection is reduced by destructive interference. The reflectivity is ≤ 0.5% (self-tested in the brand laboratory standard test environment; the transmittance/haze/impact resistance have been verified by SGS actual measurement. 2.0 uses the same process platform).

Note: The above is a physical description at the optical structure level. Visual comfort varies from person to person and does not constitute a efficacy commitment.

5.5 Comparison of Four Anti-Reflection Processes

Note: The reflectance data is a common reference value. There may be differences due to the specific product structure and test conditions.

5.6 Technical Core Parameters (Guanfudun Qu scinique® 2.0 Dual Protection Synergistic Optical Technology)

The items marked "(estimated)" in the following table are the planned values for the mass production standard of Guanfudun Qu. The final values shall be subject to the actual measurement report of mass production. The remaining data sources are the same as those of the 1.0 system.

5.7 Technical Verification

The Woowhead exclusive circularly polarized light detection card is provided as a technical accessory. The user places the detection card in front of the screen and rotates it to observe: the light picture with circularly polarized light characteristics remains uniform and soft, or only shows slight changes in brightness and darkness. Ordinary linearly polarized light will show blackening or colorful rainbow patterns. This transforms the invisible optical technology into verifiable facts.

5.7.1 Verification Principle of the detection card

The circularly polarized light detection card is a simple verification tool based on the principle of polarization optics, used to distinguish "ordinary linearly polarized light" from "scinique® optimized circularly polarized light".

· Linearly polarized light:The vibration direction is single and concentrated. When the polarization direction of the detection card is perpendicular to the vibration direction of the light, extinction will occur, and the picture will show obvious blackening or color stripes.

· Circularly polarized lightThe vibration direction rotates uniformly over time, and the components in each direction are nearly the same. When rotating the detection card, the picture only shows a slight change in brightness and does not turn significantly black.

5.7.2 Comparison of detection card phenomena for different screen/product combinations

The following table presents the "Detection Card Phenomenon" and the "Corresponding Principle Explanation" side by side. All phenomena need to be magnified and observed through a professional polarization detection card. Under normal daily use with the naked eye, there should be no obvious color or brightness abnormalities.

Important Note: The orange-yellow soft light with serial number 5 is a verifiable technical performance of the scinique® 2.0 dual-protection collaborative optical technology, featuring a double-layer circular polarization structure with phase alignment, which does not affect the color perception during daily use. It is only visible when the professional detection card is rotated to a specific Angle, and there is basically no color deviation perception with the naked eye in daily life.

5.7.3 Causes and Explanations of orange-yellow soft Light

· Cause:The scinique® 2.0 dual-protection synergistic optical technology adopts a double-layer circular polarization structure. Through narrowband phase matching, the phase parameters of the film layer and the internal structure of the screen are aligned and connected into a double-layer circular polarization structure, further reducing stray light, reflection and glare, making the screen light more uniform and closer to the characteristics of natural light. When detecting the caterpillar fixed Angle, it presents an orange-yellow soft light effect. In daily use, the human eye basically has no color deviation perception.

· Nature:It belongs to verifiable technical performance, without coating discoloration or quality abnormalities, and does not affect the color perception during normal daily use.

· Visible conditions:It is only visible when the professional circularly polarized light detection card is rotated to a specific Angle, and there is basically no color deviation perception when viewed with the naked eye in daily life.

5.7.4 Instructions for the Use of the Test Card

① Stay close to the screenPlace the test card flat on the illuminated screen, avoiding tilting or suspending it.

② Slow rotation:Rotate the detection card slowly from 0° to 360° with the center of the screen as the axis to observe the changes in the brightness and color of the picture.

③ Comparative observation:First, observe the phenomenon of bare screen (or applying ordinary film), then observe the phenomenon after applying Guanfudun, and compare the differences to verify.

Important Note: All the above phenomena need to be magnified and observed through a professional polarization detection card. Under normal use with the naked eye in daily life, there should be no obvious color or brightness abnormalities. Please do not use this as a basis for judging the effect of daily use.

Appendix: Technical Background and Visual Comfort Reference

This appendix is only for technical background reference and does not constitute a commitment to the efficacy of specific products.

In August 2009, the Chinese Journal of Preventive Medicine published a study titled "The Impact of Circularly Polarized Light LCD Television on Visual Fatigue", which conducted a control experiment by installing a 1/4λ wave plate in front of the LCD screen to convert linearly polarized light into circularly polarized light. Research inference: The polarization state of light is a variable that affects visual comfort. Circularly polarized light, which is closer to the characteristics of natural light, may help reduce the visual burden caused by prolonged viewing.

Important Note: This research focuses on LCD TV products. In June 2016, Guanfudun adopted a similar circularly polarized light optical structure.The "Light of Science and Technology" program on CCTV10Broadcast "Did You Choose the Right Screen?" and transform academic conclusions into popular science through polarizing film experiments: Linearly polarized light will darken and dim at a specific Angle, while circularly polarized light always remains uniform and soft.
