Do you want to know about the best glass treatment touch screen display that enables you to perform the best function?

From an early time, we use different products daily for the convenience of work. Tablets, smartphones, and other products with touch screens have changed how we connect with devices. They have become so common that everyone expects many screens to have touch screen interfaces. A few products might have helped your desk as AR, AG, AF, and AS, whenever you work with your touch screen display manufacturer to design touch-enabled products. In this article, you will learn the best glass treatments, what they mean, and how they will work into your designs and the consumer experience? Let’s explore glass treatments, different kinds, their cost, advantages, and disadvantages.

1. Anti-Reflective (AR) Glass Treatment

Anti-reflective glass treatment involves applying a coating or film of a specific thickness to the surface of cover lens.

Anti-reflective glass treatments, also known as AR coatings, are applied to glasses via a series of attached layers to the front and back of the lenses. The layers help block specific wavelengths of light to minimize reflection on the surface. 

  • Process 

 When a specific wavelength of light passes through the AR material, some of it is reflected by the customer at the surface of the AR film, and some of its wavelengths are reflected at the surface of the cover lens. 

The consistency of the AR film causes the reflected wavelengths to be reflected precisely out of phase with each other so that they cancel the effect of each other. 

  • Cost

This coating or glass treatment generally costs about varied from size and thickness of glasses, more important is if there any special requirements like holes, silk-printings, unusual shapes. 

AR coating glasses look nicer in photos and in bright lights, making the glass less reflective. 


2. Advantages of Anti-reflective Coating Glasses

AR coatings offer several benefits.

  • Better looking

One of the main benefits of this glass is that you will look better and increase the visibility of your eyes because you would not see the reflections in your prescription glasses. You will enhance eye contact with others and won’t be hindered by irritating reflections. This makes them ideal for people who do a lot of public speaking.

  • Durability

Another benefit is that it provides more durability as it lasts longer than regular lenses. Assume they are highly resistant to scratches and do an excellent job resisting water and dirt.

  • Reducing eye fatigue 

Also, AR coatings treatments help in decreasing eye fatigue at any work. This is suitable especially for people who spend long hours working on computers or other devices, which can cause significant eye stress. Besides using them for computer work, they are helpful while watching television to reduce eye fatigue. 

  • Improve Night vision

The anti-reflecting coating is also helpful in improving night vision.


3. Disadvantages Of  Anti-Reflective (AR) Glass Treatment

On the other hand, anti-reflective coating glasses do have disadvantages.

  • Dirty look

They look dirty due to the transparency of the lenses. Then any regular pair of glasses and anti-reflective coatings are not any dirtier. As a result, you may have to clean your lenses more repeatedly, especially for some lower-cost AR coatings.

  • Not for Reading 

This lens generally isn’t suggested for reading glasses that rest on the low bridge of the nose. If you spend a considerable amount of time using a tablet, just read inadequate light conditions.

4. Anti-Glare (AG) Glass Treatment

Anti-glare glass treatment concerns creating a rough surface on the cover lens through an etching process.

Anti-glare glass can be tempered, laminated, or chemically strengthened. Unlike anti-reflective coated or untreated surfaces, anti-glare etched glass does not become highly reflective.

Light is scattered at different angles or reflected on the rough surface, which reduces the clarity of the reflected image. 

  • Process

A chemical-based surface process is applied instantly to the surface of the glass under the likes of sunlight to form micro severities and give the glass an anti-glare effect.

  • Cost

Anti-glare coatings are not expensive. It is similar to AF treatment, also varied from size and thickness of glasses, more important is if there any special requirements like holes, silk-printings, unusual shapes. 

5. Advantages Of Anti-Glare (AG) Glass Treatment

The advantages of the anti-glare are described below:

  • Better Appearance

Cameras flashes and bright lights can reflect off your lenses when you are not using anti-glare coating on your glasses. This can cause hinder your appearance when speaking to people or in public and make it tough to find the right angle for video calls. So the Anti-reflective coating eliminates the harsh reflections and permits others to see your eyes and face.

  • Reduced Digital Eye Strain

If you feel eye strain while using a computer or other devices, use anti-glare. The anti-glare coating helps reduce digital eye strain by lowering exposure to excessive glow from excessive lighting and digital devices.

  • Safe Driving at Night

The bright headlights from cars while driving in the opposite direction can be dangerous at night. These sudden glares can lead you to focus on the view ahead presently. AR coating on your eyewear effectively reduces reflections from headlights at night and enables you to enjoy a better road view.

  • Performance Indicator

Double-sided anti-glare glass has an anti-glare effect on both glass surfaces. The key is that single-sided and overall anti-glare meet specific performance hands, and it is an upgraded product of single-sided anti-glare glass. The glare glass’s superior anti-glare performance truly eliminates the phenomenon of screen reflection.


6. Disadvantages of Anti-Glare (AG) Glass Treatment

  • Damaging Over Time

 The thin layer of anti-reflective coating can get scratched down over time, making it harder to see clearly, affecting your vision over time.

  • Headache or Eye Strain

They would not prevent all glare and light from reaching your eyes, so it may cause you to have headaches or eye strain.

7. Anti-Finger Print (AF) or Anti-Smudge (AS) Glass Treatment

Anti-fingerprint glass treatment is also a concern as an anti-smudge glass treatment reduces the ability of the cover lens to retain oils from your finger. In other words, anti-reflective glass treatment involves applying a film of a specific thickness to the surface of a cover lens.

  • Process

A liquid chemistry process generally uses AF/AS treatment, or vacuum deposition, that creates an oleophobic top coating. This layer is a chemical modification of the glass surface and is very durable compared to aftermarket AF/AS spray-on films.

The film minimizes the reflections on the surface by cutting out a specific wavelength of light as it is reflected to the user. The thickness of the AR film causes the reflected wavelengths to be reflected precisely out of phase to cancel each other out. Thus the user will not see reflection to own. Instead, they will see a more vivid display.

8. Advantages Of Anti-Finger Print (AF) or Anti-Smudge (AS) Glass Treatment

The advantages of AF or AS are described below:

  • Easy to Use

The most important benefit of the AF/AS coating is the “feel” of the treated surface because the smooth surface and the finger will float more quickly than a non-treated surface. A non-treated cover lens surface causes the user’s finger to skip, feel, or draw a singular line on the screen.

  • Improve Oleophobicity

They help Increase oleophobicity and significantly improve the comfort of cleaning fingerprint contaminated surfaces. Unmistakable fingerprints with a dry cloth wipe.

  • Durability

It offers durability for long time use.

Anti-smudge Lenses Benefit you in Several Ways:

  • Clear Vision

It offers clearer vision without smudges or dirt covering the surface of the lenses from damage. 

  • Reduce Eye Strain

When you are not straining to see through fingerprints, there is a reduction in eye strain, and you feel happy.

  12.  Final Words

There are different types of cover glass with various advantages and disadvantages for protecting an LCD display.

The display cover is just as critical as the display itself when developing a new product. The actual display component normally does not receive any protection, leaving it sensitive to environmental factors and damage from continued use. Depending on product requirements, it is often necessary to add a glass cover to protect the display from scratches while maintaining optical quality. However, not all glass is made equal. The strength, cost, color options, and available thicknesses can influence which cover glass to use.

This article will discuss the options for choosing the best cover glass for your display and application.

1. Choosing a Cover Glass For Your Display 

The top layer of a display screen module is a cover glass that acts as a protective layer to the internal display properties, allowing the liquid crystal to shine through it and create a visible image. Cover glass can be customized based on the intended display application and come in various materials and strengths of the material, which is usually correlated with scratch resistance.

The strength of the cover glass is measured by the mineral hardness and determines the material’s scratch resistance. Glass, the standard material, has a 5-7 Mohs hardness rating used for LCD cover glass. Certain industrial and medical applications require a level 7 hardness rating as a safety glass.

LCD cover glass can be customized for any application, and customizations can include strengthening, waterproofing, temperature shielding, and optical enhancements. Different materials can be added to the glass substrate to strengthen the material and prevent scratching the surface. The cover glass also includes special features and printing options.

2. Cover Glass Material

The cover glass is made of a glass substrate or different glass substrates with unique strengths and material properties and strengthened to be more durable depending on the application. 

The type of cover glass material used is up to the designer, and each glass type has different advantages, features, and prices that can be changed for the required application.


3. Heat Strengthened Glass

Heat tempered glass is a special process that involves heating the display glass to a liquid at a high temperature, strengthening the glass because the molecules get realigned into a stable pattern. Heat tempered glass heat-tempered glass is a different type of display glass and four times stronger than regular untreated glass.

Heat-treated glass and heat-tempered glass can still be broken in the right conditions, the heat-tempered glass will fragment or crack used in industries for its safety features, and heat-treated glass will break into large and sharp shards. 

4. Chemically Strengthened Glass

Chemically strengthened glass is strengthened through chemical bonding; the glass is submerged in chemicals at high heat, enabling ions to bond to holes in the glass. The chemical process adds potassium bonds in the original sodium bonds during this chemical reaction strengthening the glass while maintaining the clarity of the glass. Chemically strengthened glass maintains optical clarity during the strengthening process and can be cut or drilled after treatment.


5. Glass Hardness Scale

The Mohs hardness scale defines the mineral’s scratch resistance and is a way to measure the hardness of a mineral. This is useful for describing the hardness of different LCD glasses typically measured at a hardness level of 5-7 Mohs to create scratch-resistant displays. Certain cover glass materials will have a larger hardness scale and thus be more scratch-resistant.

Soda Lime glass is chemically treated and is a great option for LCDs that do not require extra glass protection. A standard soda-lime glass for an LCD will have a hardness rated at about 5Mohs. This glass is not fragile and will have normal durability, but it is not rated as an extra-strength display glass.

Our cover Glass is chemically strengthened. It provides more damage resistance than standard untreated glass, common in portable electronic devices because it is thin and lightweight and can also be crack-resistant, ideal for handheld devices. 

The hardness rating of Dragontrail glass is 7Mohs, which is equivalent to Gorilla Glass and is scratch resistant with this hardness rating. The Dragon glass is durable with a minimum thickness of 1.1mm.

6. Bonding Type

The cover glass is fixed to the LCD with tape or an OCA bonding material. OCA bonding is an optically clear bond applied in a thin layer of about 0.005″ -0.008″ around the bond line that holds the touch panel, cover glass, and LCD together. The adhesive is clear and will dry without staining the display’s glass and is good for delicate materials such as cover glass and touchscreens. 

7. Optical Coatings

Special features and optical coatings on the display’s cover glass can provide moisture protection and dust prevention and increase the display’s durability. The optical coating acts as a protective layer to the display’s internal circuitry and liquid crystal and acts as an adhesive to prevent moisture or dust from entering the section. The cover glass can have an extra layer of protection with an optical coating. The optical coating can protect against external elements and recommend outdoor display applications. The sealing effect of the optical coating will protect the display from harsh conditions.


 8. Common Types of Cover Glass Material

Here are the most common types of cover glass used for display modules described below:

  • Soda-lime glass
  • Low-Iron soda-lime glass
  • Aluminosilicate glass

Read More About Cover Glass in detail here.

9. Soda-Lime Glass

Soda-lime glass, also known as soda-lime float glass, is the most frequently used glass in display modules. Soda Lime glass has the features of standard glass and is the most common material you typically see used in windows. This type of glass is strong and cost-efficient, and it can range in thickness like other glasses. 

10. Low-Iron Soda Lime Glass

The same strength is slightly more expensive than conventional soda-lime float glass, and low iron soda-lime glass is more transparent and almost tint-free. This glass is commonly used as a cover for any product with a lighter white color around the display since there is no green hue to distort the coloring.


11. Aluminosilicate Glass

Aluminosilicate glass, commonly known as Gorilla Glass™ or Dragontrail™ glass.

  • Gorilla Glass

Gorilla Glass is a thin, lightweight, yet strong material. Gorilla Glass is scratch-resistant and damage resistant, and the typical applications for Gorilla Glass include smartwatches, smartphones, and tablets. Gorilla Glass can also be used for industrial and military applications where the display’s durability is essential.

  • Dragon Glass

Dragon glass is a type of cover glass treated with chemicals and heat to improve the strength of the material. The glass material is mixed with strengthening particles and heated to a liquid. This chemical and heat strengthening process makes this cover glass scratch-proof and durable. This cover glass is six times as strong as the standard soda-lime glass.

Quickly upgrade your LCD monitor with a fast, intuitive, and productive touch screen.

3. Cover Glass Benefits

Why would you need to add a cover glass to the front of your LCD? Stock coverglass material does not save your LCD against damages or scratches, leaving your LCD with significant vulnerabilities. To protect your LCD, you will need to install a premium cover glass for protection.

Display packs with strengthened cover glass substrate have become a popular solution, and utilizing a glass substrate has the superior advantage of scratch resistance, increased hardness, and higher design value. 

There are many ways to increase glass strength, but chemical strengthening is widespread. A compressive surface layer is formed when sodium ions are replaced by larger volume ions such as potassium via a high-temperature ion-exchange process. Still, this process differs from manufacturer to manufacturer. Our displays offer diverse cover glass substrate options to add protection and durability to an LCD. 


4. LCD Bonding And Its Benefits

Our displays use an integration method commonly known as LCD bonding, one of the various adhesive options available on the market for a wide range of benefits. Integrating a cover glass to the LCD requires an h2 adhesive bond to fuse two LCD components to form one unit. Normally, the cover glass is bonded straight to the LCD unit itself. Still, our displays offer three different bond integration methods: optical, OCA, and tape bond give unique benefits to an LCD design. 


  • Enhanced the cover glass treated for strength.
  • The cover glass is used in LCD and touch screen applications from industrial to a commercial levels.
  •  Optical Quality cover glass coating influences resistance, transmittance, absorbance, and reflectance.

  • Low Emissivity

This glass provides a higher window U-Value, energy savings, decreases colour fade by blocking UV light, and increases insulation performance. 


7. Optical Coatings And Its Features

One issue that may arise from the standard or enhanced front of screen structure is the reflection caused by the multiple layers in an LCD stack. To properly optimize cover glass and other enhanced elements in an LCD design, AGDisplays incorporate (optional) optical coatings to the LCD, such as anti-glare, anti-reflective, and other surface treatments. Light reflections cause a distracting flare for the LCD and contribute to overall image quality. These treatments are placed on the front surface of the display, creating different reflection patterns to reduce the negative readability reduction and enhance optical properties. Mostly, these coatings are thin-film layers that disrupt lightwave patterns. These coatings are applied to glass and other substrates and can be added by low-cost wet-coating processes. The features below are dependent on solution selection.

Optical Coating Features:

  • High Transmittance
  • Low Reflectance
  • Durability
  • Scratch and abrasion Resistance
  • Contamination and Weather Resistant
  • Easy to Clean
  • Electromagnetic Shielding
  • Oil and Fingerprint Resistant  

8. Optical Coating Selection

  • Anti-Reflective (AR) 

The AR treatment reduces ghost images often produced in builds with multiple reflective surfaces and many thicknesses. Integration of AR film optimizes the readability of a display and handles both external and internal light sources of an LCD. This means surrounding light and light reflection within the display are reflected to increase display readability for the user. This treatment features low reflectance, high transmittance, an easy-to-clean surface, and durability and is best suited for medical displays as a surface.

  • Anti-Glare (AG) 

The AG is a rough, textured coating created to diffuse reflective light, reduce glare on a screen, and streaks to increase readability. The main difference between anti-reflective technology and anti-glare technology is that AG deals with external sources of light that bounce off the surface of the LCD, such as ambient light or sunlight. 

  • Oleophobic/hydrophobic 

Oleophobic is an oil repellant coating that resists dirt, grease, water, and oil to enhance glass performance and works by repelling grease and preventing it from sticking to the glass surface. It is resistant to severe scratches and abrasions due to the oleophobic layer being more slippery, reducing friction. Oleophobic allows surfaces to be easy-to-clean and repeated removal of fingerprints, maintaining spotless image quality.

Here are some tips for keeping a prolonged oleophobic display by handling the layer with care:

  • Do not use household cleaners or alcohol-based solvents on the display
  •  Use Transparent conductive coatings 
  • Use a clean cloth and a small amount of water to remove streaks and fingerprints.

9. Final Words

All coatings, as mentioned earlier, are used in electromagnetic shielding and electrical heating display applications and allow for low reflectance. The coating features excellent infrared reflection and high visible transmission. Fine wire mesh can be conductively plated, increasing shielding effectiveness, with surface resistance numbers close to 0.1 ohms/sq, allowing for much better shielding effectiveness.
