Crystal Shield Ultra-Hard Protective Film - AR Version
Material
Lithium-Aluminum-Silicate (LAS) Tempered Glass
Thickness
0.25 mm (glass thickness only, excluding AB adhesive; tolerance ±0.05 mm)
Advanced AR Anti-Reflective Coating
Optical-grade AR coating with seven-layer magnetic sputtering technology for phase-controlled reflection cancellation, eliminating environmental light interference and restoring true screen colors without glare or rainbow patterns.
9H hardness rating tested by pencil hardness method; resistant to scratches from keys, coins, and diamond cutter wheels.
High Impact Resistance
Edge compression strength ≥ 350 MPa; passed SGS authoritative drop ball test from 1.5 meters and whole device drop test from 50 cm without damage.
Material Strength
Lithium-aluminum-silicate microcrystalline glass with glass-crystal interlocking structure, offering ultra-high light transmittance, low thermal expansion, and excellent bending resistance.
Full-Screen Coverage
1:1 precise fit for curved screens with Barefy™ arc edge technology, eliminating hard edges of 2.5D films, providing seamless edge-to-edge coverage without gaps or dust accumulation.
Anti-Glare and No Rainbow Effect
Multi-polarized light transmission design eliminates polarized light interference, ensuring clear and natural color display even when wearing polarized sunglasses outdoors.
Fingerprint Oil Coating
Imported Shin-Etsu fingerprint oil 2.0 for smooth touch and reduced fingerprint visibility.
Easy Installation
Patented Pull-Tab Speed Installation System (™) enables dust-free, bubble-free, and precise application without professional skills.
Drop Ball Test
Passed 1.5 m drop ball test certified by SGS.
Whole Device Drop Test
Passed 50 cm drop test certified by SGS.
Hardness
9H (diamond cutter wheel scratch resistant).
Edge Strength
Enhanced edge toughness for multi-angle drop resistance.
Thickness
0.25 mm (glass only).
Suitable for daily use scenarios including cycling navigation, home leisure, and outdoor activities requiring clear and comfortable screen visibility.
Material widely used in dental, aerospace, and electronic protection industries due to its superior mechanical and optical properties.
Test data are sourced from Benks laboratories. Actual performance may vary due to individual differences and environmental conditions. The product undergoes triple deep strengthening processes to achieve superior hardness and structural stability beyond ordinary glass.
