Start With AG Glass
Use AG when distinct reflected images and point-source glare interfere with reading. Confirm the display trade-off on physical samples.
- Haze and gloss
- Sparkle on the target pixel density
- Display gap and viewing distance
Engineering Overview
Choose the Surface Function Before the Coating
AG, AR and AF are often grouped together because all three change the user experience of a glass surface, but they solve different problems. AG redistributes reflected light, AR reduces specular reflection and AF lowers surface energy so oils and contamination release more easily.
ITO and TCO add an electrical function. They are specified through sheet resistance, transmission, film type, active area and electrode geometry. Treating these five routes as interchangeable produces incomplete RFQs and unreliable comparisons.
Start with the dominant problem.Describe what must change in the assembled product, then define the metric and test method used to approve it.
Five Functions and Their Primary Metrics
| Anti-Glare AG | Reflected-image diffusion, haze, gloss, sparkle and display clarity |
|---|---|
| Anti-Reflective AR | Reflectance spectrum, transmission, residual color and angle of incidence |
| Anti-Fingerprint AF | Initial and retained contact angle, wipe effort, friction and cleaner resistance |
| ITO Conductive | Sheet resistance, transmission spectrum, pattern, busbar and coating uniformity |
| TCO Coated | Oxide type, conductivity, transmission, haze, thermal stability and fabrication route |
| Approval | Drawing, data sheet, measurement geometry and production-intent sample |
Reference ranges are used for discussion only. The quotation identifies the controlled values and inspection method.
Five Coated Glass Product Families
Each page uses the acceptance metrics that buyers actually use for that surface function.
Diffuse Reflection
Anti-Glare AG Glass
Matte microtexture selected through haze, gloss, sparkle and display readability.
Reduce Reflection
Anti-Reflective AR Glass
Thin-film optical coatings designed around wavelength, angle, color and durability.
Easy Clean
Anti-Fingerprint AF Glass
Oleophobic and hydrophobic top surfaces defined by retained cleanability.
Transparent Electrode
ITO Conductive Glass
Sputtered conductive glass with specified sheet resistance and optical transmission.
Durable Conductive Oxide
TCO Coated Glass
ITO or FTO-family routes for heating, PV, shielding and active glazing.
Find the Correct Functional Surface Route
Choose the primary failure or performance target. The result identifies the first specification to write.
Start With AR Glass
Use AR when the goal is lower specular reflection and higher transmission within a defined spectral band.
- Wavelength range
- Average or maximum reflectance
- Angle, side count and residual color
Start With AF Glass
Use AF when cleanability and touch feel matter. Specify both initial performance and the retained result after wear.
- Contact angle
- Abrasion load and cycles
- Cleaner and wipe method
Start With ITO Glass
Use ITO when transparent conductivity, patterning and a controlled electrode geometry are central.
- Sheet resistance
- Transmission spectrum
- Active area and busbars
Start With TCO Glass
Use a TCO route when oxide type, heat stability, haze or large-area processing drives the design.
- FTO versus ITO
- Transmission and haze
- Downstream tempering, bending or lamination
Technical Education
One Glass Surface Can Carry Several Functions
A finished interface may use an etched AG surface, an AR interference stack and an AF top layer, while printing sits on the opposite face. A transparent conductor introduces another functional plane. The sequence matters because a later process can change adhesion, optical response or electrical continuity. The RFQ should therefore show every surface in a cross-section and label which side faces the user, display, sensor or environment.

Control Function, Orientation and Process Sequence
A general coating label is not enough for production. Each functional surface needs an orientation, measurable target and release method.
Production Route
- 01Specification Review
Lock substrate, coating side, optical or electrical target, test method and downstream process.
- 02Substrate Preparation
Complete cutting, CNC, edge work, cleaning and any compatible strengthening before the controlled coating step.
- 03Surface Processing
Apply the selected etch or coating route with orientation, masking and handling controls.
- 04Functional Inspection
Measure the page-specific optical, surface or electrical characteristics and record uniformity.
- 05Cosmetic Release & Packing
Inspect controlled zones and protect the functional surface against contact and contamination.

Questions That Prevent the Wrong Coating
Resolve the dominant surface problem before comparing supplier numbers.
Is anti-glare glass the same as anti-reflective glass?
No. AG scatters reflected light so distinct images are less visible. AR reduces reflected energy through an optical thin-film design.
Does AF coating reduce glare?
AF primarily changes cleanability and touch feel. It does not replace a specified AG or AR requirement.
Can AG, AR and AF be combined?
Selected stacks can be combined, but process sequence, optical trade-offs, adhesion, touch and durability require sample validation.
Is ITO the same as TCO?
ITO is one transparent conductive oxide. TCO is the broader family and can include ITO, FTO and other conductive oxide systems.
Which test data should be included in an RFQ?
Include the functional target, measurement method, wavelength or geometry, initial and aged limits, coating side and production sample approval conditions.
RFQ and Manufacturing Review

A useful request identifies the assembled product and the test result that determines acceptance. The review identifies the proposed substrate, coating route, measurement method, sample plan and open technical points.
