AG (Anti-Glare) glass is widely used in displays to reduce reflections, improve visibility, and enhance user experience. FELIX GLASS provides both single side AG glass and double sided AG glass to meet different application requirements. The following is a detailed comparison and introduction to their differences:### 1. Definition & Coating Structure- **Single Side AG Glass**: This type of glass has an Anti-Glare coating applied to only one surface. The other surface remains a smooth, untreated glass (or can be treated with AR/AF coatings). It is suitable for applications where the back surface does not require anti-glare treatment.- **Double Sided AG Glass**: This type has uniform Anti-Glare coatings applied to both the front and back surfaces. Both surfaces have a matte finish that scatters light, effectively reducing reflections from both sides.### 2. Core Performance Differences| Aspect | Single Side AG Glass | Double Sided AG Glass || :--- | :--- | :--- || **Reflection Control** | Reduces reflections on the coated side only. | Reduces reflections on both sides, offering comprehensive anti-glare protection. || **Light Transmittance** | Slightly higher transmittance as only one side is treated. | Slightly lower transmittance compared to single side due to double-sided light scattering, but still within high performance standards. || **Application Scope** | Standard displays, backboards, or cases where only one side is visible. | Transparent displays, laminated screens, or applications where both sides may be exposed to light. || **Cost** | Relatively lower cost due to single-side processing. | Higher cost due to double-side processing and higher material consumption. |### 3. Application Scenarios- **Single Side AG Glass**: Ideal for most consumer electronics displays (such as monitors, TVs, and mobile phones) where the back of the screen is enclosed and not visible to the user. It is also used for decorative glass panels and touch sensors.- **Double Sided AG Glass**: Preferred for automotive displays (like head-up displays and rear-seat entertainment systems), medical devices, and industrial control panels. These scenarios require the display to be visible from multiple angles or both sides, making double-sided anti-glare essential.### 4. Processing & Durability- **Single Side AG**: The processing is simpler, with faster production lead times (typically 3-7 days). It is durable against scratches on the uncoated side if handled properly.- **Double Sided AG**: The processing is more complex, requiring precise alignment of both surfaces. It offers superior durability as both surfaces are protected, making it more resistant to wear and tear.### 5. FELIX GLASS CustomizationAt FELIX GLASS, we can customize both single and double sided AG glass to meet your exact specifications:- **Coating Thickness**: Adjust the roughness to achieve different haze levels (10%-30%).- **Material Options**: Available in BK7, K9, Sapphire, or high-quality float glass.- **Combination Coatings**: We can combine AG with AR (Anti-Reflection) or AF (Anti-Fingerprint) coatings on either or both sides for a comprehensive solution.If you need a diagram comparing single and double sided AG glass structures, please contact our technical team for support.

No matter it’s single side AG glass or double sided AG glass, both can be silkscreen printed. it is absolutely possible to print on the side (edge) or surface of AG (Anti-Glare) glass, and FELIX GLASS has rich professional experience and mature technology in this field, providing customers with high-quality custom printed AG glass solutions for various application scenarios.### 1. Feasibility of Printing on AG GlassAG glass has a micro-rough anti-glare surface formed by physical or chemical etching, which is different from the smooth surface of ordinary glass. This micro-rough structure can increase the adhesion of ink, making printing more firm and durable, and not easy to fall off. At the same time, we can choose to print on the edge (side) of the glass or the non-AG surface of the glass according to customer needs, avoiding affecting the anti-glare effect of the AG surface. For edge printing, we use professional edge grinding and pretreatment technology to ensure the flatness of the edge, providing a good printing base.### 2.

Haze is a core optical performance indicator for glass, especially AG (Anti-Glare) glass, and its unit is **percentage (%)**. It is used to quantify the degree of light scattering when light passes through the glass, which directly affects the anti-glare effect, clarity, and visual experience of the glass.### 1. Definition and Unit of HazeHaze, also known as turbidity, is defined as the percentage of the transmitted light that deviates from the incident direction by more than 2.5° when parallel light passes through the glass, relative to the total transmitted light. The calculation formula is:**Haze (%) = (Scattered Transmitted Light / Total Transmitted Light) × 100%**The unit of haze is percentage (%), which is a dimensionless percentage value, used to intuitively reflect the light scattering ability of the glass. The higher the haze value, the stronger the light scattering ability of the glass, the better the anti-glare effect, but the slightly lower the clarity; the lower the haze value, the weaker the light scattering, the clearer the glass, but the slightly worse the anti-glare effect.### 2. Measurement Standard and Method of HazeThe measurement of haze is carried out in strict accordance with international standards, such as **ASTM D1003** and **ISO 14782**. We use professional haze meters (also called transparency and haze meters) for measurement. The measurement process is as follows:- **Instrument Calibration**: Calibrate the haze meter with a standard sample before measurement to ensure measurement accuracy.- **Sample Preparation**: Clean the glass sample to be tested to ensure no dust, oil, or scratches on the surface, avoiding affecting the measurement results.- **Measurement**: Place the sample in the haze meter, emit parallel light to pass through the sample, and the instrument automatically measures the total transmitted light and scattered transmitted light, and calculates the haze value.- **Multiple Measurements**: Conduct multiple measurements on different positions of the sample to ensure the uniformity of the haze value of the glass.### 3. Haze Range of AG Glass and Application ScenariosFELIX GLASS can customize the haze value of AG glass according to customer needs, and the common haze range is **5% to 30%**, which is suitable for different application scenarios:- **Low Haze (5%-10%)**: High clarity, slightly weaker anti-glare effect, suitable for indoor high-end displays, VR/AR headsets, and medical devices that require high visual clarity.- **Medium Haze (10%-20%)**: Balance between anti-glare effect and clarity, the most commonly used haze range, suitable for automotive displays, industrial control screens, and consumer electronics touch screens.- **High Haze (20%-30%)**: Strong anti-glare effect, slightly lower clarity, suitable for outdoor displays, public kiosks, and bright environments that require strong anti-glare.### 4. FELIX GLASS's Haze Control TechnologyWe have advanced AG coating and etching technology, which can precisely control the haze value of AG glass, ensuring the uniformity and stability of the haze value of the same batch of products:- **Precision Etching Technology**: Control the micro-roughness of the glass surface by adjusting the etching process parameters, so as to accurately control the haze value, with a control accuracy of ±1%.- **Uniform Coating Technology**: Use vacuum coating technology to form a uniform anti-glare coating on the glass surface, ensuring that the haze value of each position of the glass is consistent, with no local difference.- **Haze Quality Inspection**: Conduct 100% haze inspection on each AG glass product to ensure that the haze value meets the customer's specified range, and provide a detailed haze test report.### 5. Factors Affecting Haze ValueThe haze value of glass is mainly affected by the following factors:- **Surface Roughness**: The higher the surface roughness of AG glass, the higher the haze value.- **Coating Thickness and Uniformity**: The thickness and uniformity of the AG coating directly affect the haze value.- **Glass Thickness**: The thicker the glass, the slightly higher the haze value, but the impact is small.- **Measurement Environment**: The temperature, humidity, and light environment during measurement will affect the measurement results, so we carry out measurement in a standard laboratory environment.### 6. How to Choose the Right Haze ValueWhen choosing the haze value of AG glass, you need to comprehensively consider the application scenario, use environment, and visual requirements:- **Outdoor Use**: Choose high haze (20%-30%) to resist strong sunlight reflection.- **Indoor High-End Use**: Choose low haze (5%-10%) to pursue high clarity.- **General Touch Screen Use**: Choose medium haze (10%-20%) to balance anti-glare and clarity.FELIX GLASS's professional technical team can provide you with professional haze value selection suggestions according to your product application scenarios and requirements, and customize AG glass products with the most suitable haze value to meet your visual and performance needs.

Question: How to recognize the etched side?Answer:Recognizing the etched (AG/anti-glare) side of optical glass is crucial for quality control and application matching. Here are 3 practical and high-precision methods: 1. Visual Light Reflection Test (Most Used)Place the glass under natural light or fluorescent lamps. Observe the light reflection on both sides: the etched side will produce diffuse reflection, with blurred and scattered light (matte, non-glare effect); the non-etched side will form a clear, mirror-like specular reflection of the light source. This method is the most convenient and widely used in on-site inspection, with 100% accuracy for standard AG glass.2. Tactile Touch TestGently slide your finger across the glass surface. The etched side has a matte, slightly rough texture (smooth and non-sticky hand feeling), while the non-etched side is smooth and flat. Note: This method is not suitable for AF-coated glass, as the AF layer will change the surface touch feeling.3. Backlighting Transparency TestHold the glass up to a strong light source and observe from the opposite side. The etched side shows a frosted, semi-opaque matte effect, while the non-etched side is fully transparent. This method is especially effective for high-haze AG glass, making it easy to distinguish even for thick glass. In summary, the visual light reflection test is the first choice for quick identification, and it can be combined with the tactile test for double verification. Our AG optical glass undergoes strict process control, ensuring clear distinction between etched and non-etched sides and stable product performance.

Question: For AF(Anti-Fingerprint) coating, how much is the qualified water contact angle?Answer:AF (Anti-Fingerprint) coating, also known as oleophobic coating, is a high-performance functional coating based on perfluoropolyether materials, which is widely used on optical glass, display panels, touch screens and other optical components. Its core function is to endow the glass surface with excellent hydrophobic and oleophobic properties, effectively reducing the adhesion of fingerprints, oil stains and water stains, and achieving an easy-to-clean effect. The water contact angle (WCA) is the most core and authoritative quantitative index to evaluate the performance and qualification of AF coating, and its industry standards and testing principles are clearly defined as follows: 1. Industry Qualification Standards for Water Contact Angle The water contact angle refers to the angle between the tangent of a static water drop and the glass surface, which directly reflects the surface energy of the coating: the larger the angle, the lower the surface energy, and the better the hydrophobic and anti-fingerprint performance. The industry's unified qualification standards are divided into three levels: - Basic Qualified Standard (Entry Level): For general consumer electronics, daily display glass and other conventional applications, the initial water contact angle of qualified AF coating must be ≥ 105°. This is the minimum threshold to ensure basic anti-fingerprint and easy-to-clean performance, which can effectively reduce the adhesion of daily fingerprints and oil stains, and is the most widely used standard in the market.- High-Quality Standard (Mid-to-High End): For automotive displays, industrial touch screens, outdoor display screens and other medium and high-end application scenarios with high durability requirements, the qualified standard is ≥ 110°. This level of coating has lower surface energy, better hydrophobic and oleophobic effects, and can maintain stable performance in complex environments such as high temperature and high humidity.- Premium Flagship Standard (Top Level): For high-end smart phones, professional optical instruments, medical display glass and other top-level products, the strictest requirement is ≥ 115°. This level of AF coating has ultra-low surface energy, excellent anti-fouling performance, and can achieve a "water drop rolling without leaving a trace" effect, which is the highest standard in the industry. 2. Performance Grading and Unqualified Judgment To help customers intuitively judge the quality of AF coating, we have formulated a clear performance grading standard based on water contact angle: - WCA - 90° - 105° ≤ WCA - 110° ≤ WCA - WCA ≥ 115°: Premium flagship grade, with ultra-high performance, suitable for high-end optical products and professional instruments. 3. Testing Principle and Additional Durability Requirements The water contact angle is tested by the static sessile drop method, which is the international standard testing method: 1. Drop 2-5μL of pure water on the surface of the AF coating to be tested, keep the glass horizontal and static.2. Use a professional contact angle measuring instrument to capture the shape of the water drop, and measure the angle between the tangent of the water drop and the glass surface, which is the water contact angle value. In addition to the initial water contact angle, a truly qualified AF coating must also pass the friction resistance durability test, which is an important indicator to distinguish low-quality and high-quality coatings: - After 3000 times of standard steel wool friction (load 1kg), the water contact angle of qualified coating should still be ≥ 100°, ensuring long-term use without performance degradation.- For high-end automotive and industrial grade coatings, it is required to maintain a water contact angle ≥ 105° after 5000-8000 times of friction, with extremely high durability. 4.

Question: Will the glass strength be affected after AG etching?Answer:AG (Anti-Glare) etching is a core surface treatment process for optical glass, which forms a uniform micro-rough structure on the glass surface through chemical etching, effectively reducing specular reflection and glare, and is widely used in display panels, touch screens, automotive displays, industrial equipment and other fields. A common concern from customers is whether AG etching will damage the mechanical strength of the glass. The clear conclusion is: with professional, strictly controlled AG etching process, the glass strength will not be negatively affected, and can even maintain or exceed the mechanical performance of the original glass. 1. Mechanism Analysis: Why AG Etching Won't Weaken Glass Strength Many customers mistakenly believe that "etching removes glass material, so it will reduce strength", but this is a misunderstanding caused by ignoring the process principle. The core reasons why professional AG etching will not affect glass strength are as follows: - Minimal Material Removal: The AG etching process only removes a very thin layer of glass surface, usually only 5-20μm, which is less than 1/50 of the total thickness of conventional display glass (0.5mm-1.1mm). This extremely small material removal has a negligible impact on the overall mechanical load-bearing capacity of the glass.- No Harmful Micro-Cracks Introduced: The key to glass strength lies in whether there are sharp micro-cracks on the surface, which are the source of stress concentration and fracture. Professional chemical AG etching uses strictly controlled acid concentration, temperature, time and stirring speed, which can form a uniform, stress-free micro-pit structure on the glass surface, avoiding the generation of sharp micro-cracks, and will not become a hidden danger of strength failure.- No Damage to Strengthened Layer: For chemically strengthened glass (such as Gorilla Glass, aluminosilicate glass) commonly used in high-end displays, the AG etching process only acts on the outermost surface of the glass, and will not damage the internal ion exchange stress layer, so the glass can still maintain the high strength brought by the strengthening process. 2. Process Control: The Core Guarantee of Glass Strength To ensure that AG etching does not affect glass strength, strict process control in all links is essential: - Single-Sided Etching Protection: Use high-temperature resistant protective film to protect the non-etched side of the glass during the etching process, avoiding acid corrosion and damage to the opposite side, ensuring the integrity of the glass structure.- Precise Etching Parameter Control: Strictly control the concentration of hydrofluoric acid, etching temperature, time and other parameters, avoid over-etching, and ensure that the surface microstructure is uniform and free of defects.- Post-Etching Stress Relief Treatment: After etching, the glass undergoes edge polishing, cleaning and stress relief annealing treatment, eliminating the edge stress concentration caused by cutting and etching, further improving the overall strength of the glass.- Strict Quality Inspection: Each batch of AG glass undergoes 100% appearance inspection and mechanical performance sampling inspection, including flexural strength test, impact test, drop test, etc., to ensure that the strength meets the industry standards and customer requirements. 3. Performance Data and Application Verification A large number of industry tests and practical applications have fully verified that professional AG etching will not reduce glass strength: - Flexural Strength Test: The flexural strength of AG etched glass is basically the same as that of the original glass, and even slightly improved in some cases, because the uniform micro-rough structure can disperse the surface stress.- Impact and Drop Test: AG glass has been widely used in automotive displays, industrial touch screens, outdoor display screens and other harsh environment applications, and can pass the strict drop test, impact test and vibration test required by the industry, fully meeting the mechanical performance requirements of terminal products.- Long-Term Durability: The AG etched surface has stable chemical properties, and will not cause strength degradation during long-term use, temperature changes and humidity changes, ensuring the service life of the product. 4.
