HUIBAO RED LIGHT MATERIAL TECHNICAL NOTES — ENGLISH EDITION
Reviewed: October 13, 2026

This HUIBAO edition explains the material technology used in red-light conversion. The E60 and E90 specifications below are English translations of grade-specific technical sheets dated June 8, 2026. They describe base-film materials, not the total thickness or clinical performance of every finished retail protector. These notes are not a new laboratory report or an amended patent certificate.

1. QUANTUM-DOT RED-LIGHT BASE FILM: ZJQF-E60-01
Product family: ZJQF-E quantum-dot red-light base film.
Construction, nominal: inner PET carrier 23 micrometres; red-light quantum-dot layer 17 micrometres; outer PET carrier 23 micrometres.
Carrier roll widths: 1090 mm. Effective width: 1050 mm.
CIE 1931 x coordinate: 0.190–0.215; luminance-meter method.
Red-light conversion rate: at least 30%; luminance-meter method stated in the sheet. The sheet does not supply a full conversion-rate definition or complete excitation setup.
Haze: at most 2%; haze meter, ASTM D1003.
Transmittance: at least 87%; haze meter, ASTM D1003.
Red emission peak: 630 ± 5 nm; luminance-meter method.
Red emission full width at half maximum: at most 45 nm; luminance-meter method.
Base-film thickness: 60 ± 5 micrometres; thickness gauge.
Appearance and uniformity: no significant defects. Foreign particles of diameter d ≤ 0.4 mm are not counted if they do not impair lamination; particles with 0.4 mm < d ≤ 2 mm are limited to 10 per square metre; particles with d > 2 mm are not permitted. Visual inspection under fluorescent lighting.
The nominal layer dimensions and the specified overall thickness are reproduced separately as stated. Do not treat nominal layer values as a measured finished-stack thickness.

Storage and industrial handling:
Store packaged material horizontally in a dry environment away from light, at 23 ± 3 degrees Celsius and 50 ± 10% relative humidity. The sheet's material guarantee period is 180 days from shipment while unopened and stored within those conditions; this is not the HUIBAO retail returns or warranty policy.
Avoid folding, impact and rubbing against other materials. Wear clean cleanroom rubber gloves and hold film by its edges. Use antistatic equipment as appropriate and clean compressed air to remove debris. AB adhesive processing temperature should not exceed 140 degrees Celsius.

2. QUANTUM-DOT RED-LIGHT BASE FILM: ZJQF-E90-02
Construction, nominal: inner PET carrier 50 micrometres, width 1170 mm; red-light quantum-dot layer 17 micrometres; outer PET carrier 23 micrometres, width 1090 mm. Effective width: 1050 mm.
CIE 1931 x coordinate: 0.190–0.215; luminance-meter method.
Red-light conversion rate: at least 30%; luminance-meter method stated in the sheet, with the same definition limitation noted above.
Haze: at most 2%; haze meter, ASTM D1003.
Transmittance: at least 87%; haze meter, ASTM D1003.
Red emission peak: 650 ± 5 nm; luminance-meter method.
Red emission full width at half maximum: at most 45 nm; luminance-meter method.
Base-film thickness: 90 ± 5 micrometres; thickness gauge.
Appearance limits, storage conditions and general handling: as stated for E60 above.
AB adhesive processing: the sheet recommends coating silicone on the inner side of the roll to maintain air-release behavior.

3. BASE-FILM AND OCA CONSTRUCTIONS
The base-film approach places quantum dots in a PET composite functional film. An OCA approach incorporates functional material in optically clear adhesive. A finished protector can also include glass, OCA, silicone adhesive and release films used during production. The functional base film is not the whole protector.
The construction comparison describes barrier-layer, dispersion and edge-stability differences. Its approximate conversion and lifetime comparisons lack a full shared test protocol; they are not universal lifetime guarantees or a measured comparison against every competing product.

4. HANDBOOK V5.0: TECHNOLOGY IN ENGLISH
The handbook describes base-film, privacy-base-film and AB-adhesive material options. Availability of a material option does not establish that a corresponding retail HUIBAO product is on sale.
Suitable incoming light excites the quantum dots; the functional layer emits red light at a longer wavelength. Some emitted light is guided within the transparent stack and exits at the edges. Visible edge emission depends on the lighting conditions.
The handbook base-film specification uses 10% conversion, transmittance of at least 85% and emission width at most 50 nm. The dated grade-specific sheets use different values. Do not combine these specifications into one finished-product claim or assume the conversion percentages share the same calculation.
HUIBAO therefore describes blue-to-red conversion without assigning one universal conversion percentage to all retail models.

5. SKIN, EYE COMFORT AND EVENING SCREEN USE
Red-light photobiomodulation research studies controlled exposure to particular wavelengths using dedicated light sources. Skin research examines cell signaling, collagen metabolism and changes in skin appearance. Eye research uses dedicated equipment and clinical protocols. These topics explain interest in red wavelengths; the controlled exposure cannot be assumed to match ordinary phone use.
Wavelength, irradiance, exposure duration, energy per area and distance all matter. A base-film emission peak does not establish a clinical dose or guarantee a skincare, eye-treatment or sleep outcome from a finished protector.
HUIBAO combines a quantum-dot optical layer with tempered-glass protection for everyday iPhone use. Match the full phone model, check case clearance and read the selected listing for current contents and price.

6. PATENT DOCUMENTATION
The material technology portfolio includes luminescent-composite and polymer-based optical-material inventions. The original documents retain their legal titles, inventors and named rights holders. This HUIBAO English edition explains technology; it does not amend those records or act as a medical certification.
