DisplayMan supplies AF Cover Glass for capacitive touch panels, TFT LCD modules, OLED displays, handheld devices, medical equipment, commercial terminals, public-use touch screens and OEM electronic products.
AF means Anti-Fingerprint. It is a surface coating used to reduce visible fingerprint marks, improve surface smoothness and make the glass easier to clean.
Customization can include glass size, thickness, AF process, surface smoothness, water contact angle, oil resistance, abrasion resistance, printing, chemical strengthening, AG + AF, AR + AF, bonding and enclosure matching.
Choose AF Cover Glass when a product needs a cleaner touch surface, smoother finger operation and easier maintenance. AF reduces fingerprints but does not make the glass permanently fingerprint-free.
The correct AF direction depends on touch frequency, cleaning method, product appearance, coating durability, optical structure, bonding and environment.

| AG + AF Cover Glass | Bright environments and frequent-touch surfaces | Selected when glare reduction and easier cleaning are both required |
| AR + AF Cover Glass | Premium frequent-touch displays | Selected when optical clarity and fingerprint resistance are both required |
| Custom AF Cover Glass | OEM products with special size, shape, printing, process or bonding requirements | Selected when standard cover glass cannot match the product structure |
AF Cover Glass is a surface-treated cover glass. For touch input, it must be combined with a Capacitive Touch Panel, selected Resistive Touch Panel structure or a complete touch-display assembly.
AF coating reduces the visibility and adhesion of oily fingerprint marks and smudges.
The front surface is generally easier to wipe during regular product maintenance.
AF improves the surface but cannot keep glass permanently free from fingerprints.
Helps keep frequent-touch products visually cleaner during daily use.
Useful for public terminals, medical equipment and commercial products.
Can improve the finger-sliding experience on capacitive touch panels.
Suitable for kiosks, POS, access control, smart panels and handheld devices.
AG + AF and AR + AF can be reviewed for combined optical and maintenance needs.
Glass, coating, printing, strengthening, touch and bonding can be customized together.
A common anti-fingerprint direction for surface smoothness and easier cleaning.
Normally reviewed when stronger wear resistance and longer coating life are required.
| Factor | Coated AF | Plated AF |
|---|---|---|
| Process | Common surface-coating direction | Higher-durability plated or project-specific direction |
| Cost Direction | Usually lower | Usually higher |
| Wear Resistance | Depends on coating system | Normally reviewed for stronger durability |
| Best For | General commercial and consumer-style products | Higher-use or higher-durability products |
| Selection Logic | Choose by cost, touch frequency and required life | Choose when abrasion and cleaning durability have higher priority |
AF process should be selected according to product use, touch frequency, cleaning method, abrasion, required coating life, cost and quantity.
| Parameter | What It Affects | Engineering Note |
|---|---|---|
| Surface Smoothness | Finger sliding and touch feel | Should match the required user experience |
| Fingerprint Resistance | Visibility and adhesion of finger marks | Must be evaluated under real handling conditions |
| Water Contact Angle | Surface repellency to water droplets | Useful as one indicator but not a complete AF specification |
| Oil Resistance | Adhesion and cleanability of oily marks | Important for frequent-touch and handheld products |
| Abrasion Resistance | Coating life after repeated touching or wiping | Test conditions should match actual use |
| Cleaning Durability | Performance after repeated cleaning | Cleaning agent, cloth and frequency must be considered |
| Light Transmittance | Display brightness and optical loss | Should match the LCD or OLED optical target |
| Glass Thickness | Strength, weight and capacitive-touch sensitivity | Thicker glass may require PCAP retuning |
A high water contact angle does not automatically guarantee strong fingerprint resistance or long coating life. Oil resistance, abrasion, cleaning durability, surface feel and real-use testing also matter.
AF coating can reduce fingerprints and improve cleanability, but its performance depends on coating process, usage, abrasion, cleaning method, product environment and the complete glass stack.
Resistive touch uses pressure through a flexible surface, so AF must be reviewed with the complete top-film structure.
| Bonding Direction | Description | Main Review Factors |
|---|---|---|
| Air Bonding | AF Cover Glass or touch assembly is mounted with an air gap | Cost, dust sealing, internal reflection, rework and support |
| Frame Bonding | Perimeter adhesive is used around the viewing area | Bonding width, flatness, dust control and enclosure pressure |

AF Cover Glass is anti-fingerprint cover glass. It uses a surface coating to reduce visible fingerprint marks, oil stains and smudges, improve surface smoothness and make the glass easier to clean.
No. AF coating can reduce fingerprint visibility and improve cleanability, but it does not make the glass completely or permanently fingerprint-free.
No. AF Cover Glass is a surface-treated cover glass. Touch function requires a capacitive touch sensor, resistive touch structure, FPC, controller IC or a complete touch-display assembly.
AF coating reduces the surface energy of the glass, helping oil, moisture and fingerprints spread less strongly and making the surface easier to wipe.
Coated AF is a common cost-effective direction. Plated AF is normally reviewed when stronger wear resistance and longer coating life are required, although cost is usually higher.
No. The correct process depends on touch frequency, abrasion, cleaning method, durability target, cost and quantity.
Water contact angle is one indicator of surface repellency. A higher contact angle generally means water forms a more rounded droplet and spreads less on the surface.
No. Contact angle is only one parameter. Fingerprint visibility, oil resistance, abrasion resistance, cleaning durability, touch feel and coating life must also be considered.
Oil resistance describes how strongly oily fingerprints and smudges adhere to the surface and how easily they can be removed.
Abrasion resistance describes how well the AF coating maintains its performance after repeated touching, wiping or mechanical wear.
Yes. AG plus AF can be reviewed when the product needs both glare reduction and easier cleaning.
Yes. AR plus AF can be reviewed when the product needs both reflection reduction and fingerprint resistance.
A combined AG plus AR plus AF structure can be reviewed for selected projects, but process compatibility, optical performance, surface feel, durability, cost and quantity must be evaluated.
Yes. AF Cover Glass is commonly used with capacitive touch panels because users touch the front glass directly. Coating durability, glass thickness, touch sensitivity, bonding and cleaning should be reviewed together.
Selected structures can be reviewed, but resistive touch normally uses a flexible pressure-sensitive top surface. Matte anti-glare or anti-Newton-ring treatment may be more practical for many resistive-touch applications.
Yes. AF Cover Glass can be used for touch or non-touch TFT LCD, OLED and transparent OLED products when the front surface is frequently handled or cleaned.
Yes. Chemical strengthening can be reviewed according to glass size, thickness, holes, edge distance, strength target and production process.
Yes. Black border, white border, logo, icons, button marks, windows and multi-color back-side printing can be reviewed.
Yes. AF Cover Glass can be air bonded, frame bonded or optically bonded with a capacitive touch panel, TFT LCD or selected OLED module.
Please provide glass size, thickness, 2D drawing, viewing window, AF process preference, durability target, water contact angle if known, oil resistance, abrasion requirement, cleaning method, strengthening, printing, holes, notches, edge treatment, AG or AR combination, matched touch panel or display, bonding method, environment, quantity and replacement sample if available.
Send us the glass size, thickness, 2D drawing, AF process, water contact angle, oil resistance, abrasion target, cleaning method, printing, strengthening, combined treatment, bonding, matched touch panel or display, quantity and schedule.
DisplayMan will review whether coated AF, plated AF, AG + AF, AR + AF or another front-glass direction better matches the product use and durability target.
AF Cover Glass is an anti-fingerprint surface treatment, not a touch function. It reduces visible marks and improves cleaning, but the coating will still wear according to touch frequency, abrasion, cleaning and environment.
Please share your application, display size, quantity and project background. We will review the most practical display direction.
