AF (Anti-Fingerprint) coating itself does NOT create blue light reflection. The purple & bluish tint you see comes from AR anti-reflection film optical interference or extra blue-light-blocking coating, not the AF layer.
Core Breakdown
✅ AF coating: Ultra-thin oleophobic nano coating only for fingerprint & oil resistance, no color reflection.
✅ AR film reduces surface reflection via light interference, leaving residual blue-purple glow.
✅ Many mix up combined AR+AF/blue-light-blocking glass as pure AF glass. Pure AF glass shows nearly colorless reflection only.
Quick Feature Differentiation
AF: Anti-smudge & slippery touch
AR: Lower reflection & higher light transmittance
Blue-light coating: Blocks harmful short-wave blue light
AF sits on the top surface, while AR/blue-light layers are underneath — they can be combined but work on separate mechanisms.
If your marked AF glass reflects blue light, it is integrated with AR or anti-blue-light function instead of being pure AF treatment.
Our AF Anti-Fingerprint Tempered Glass for Touch Kiosks
Our AF tempered glass adopts top fluorine-based anti-fingerprint coating applied on standard tempered glass, ideal for self-service kiosks, payment terminals, ticketing & queue management machines. We also support AG+AF and AR+AF composite coating, compatible with LCD optical bonding.
Key Merits
Excellent stain resistance, minimizes daily cleaning workload
Full transparency without blurred display, better visual performance compared with standalone AG glass
Ultra-smooth touch experience for electronic signature, PIN input and multi-touch operation
Tempered glass substrate delivers explosion-proof and impact resistance, available for all screen sizes
Limitations
Surface coating will gradually wear out under harsh scraping or rough wiping
No anti-glare capability; screen visibility deteriorates under strong direct sunlight
Not suggested for long-term standalone outdoor deployment
Harsh disinfectants and high-concentration alcohol will damage the coating
For high-brightness outdoor kiosk applications:
Under extreme sunlight exposure scenarios, we offer optional 3M solar control film installation. This film effectively cuts intense solar radiation, lowers screen surface temperature, reduces glare and prolongs the service life of the display module.
We provide custom cover glass (AF / AG+AF / AR+AF) and professional optical bonding services for touch kiosk projects.
