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.

9. Disadvantages Of Anti-Finger Print (AF) or Anti-Smudge (AS) Glass Treatment

  • Expensive
  • They can wear off and are a more expensive option in the long run.

  3. Customized LCD
  4. Important Information To Design Custom LCD Panel
  5. Advantages Of Custom LCD
  6. Disadvantages Of LCDs

  8. Final Words

Are you confused about how to choose a standard vs. custom LCD module for your use?

No need to worry now. Today in this article, I’ll explain everything about how you can choose the best LCD module according to your need. When considering a display module for your project, you will have to answer: “Should I design a standard module or customized one for my use?”  This article has described some tips, common misconceptions, and detailed answers to common questions to help you choose the best one.

1. Common Misconceptions About LCD

Here are some common misconceptions about LCD you kneed to know before your final decision.

  •  Custom LCD Modules Are Costly.

The common misconception is that custom display modules cost more than standard modules.

While the above holds for NRE cost, custom LCD module unit pricing is often equivalent to or lower than a similar product.

Here’s why: Standard display modules are often designed to maximize their implementation potential.

This can lead to:

  1. variable interface protocols allowed by high pin counts,
  2. high-output backlighting to maximize application potential,
  3. Generally conservative mechanical design practices.
  • Custom NRE Costs Are Too Restrictive.

For most Passive Matrix LCD modules, we can deliver a custom LCD with active area size and resolution or a custom backlight, mechanical housing, and electrical interface for a total NRE cost of less than USD 10k. Likewise, Createxplay can customize an Active Matrix LCD module’s backlight, housing, and mechanical interface for an NRE cost of less than USD 10k. 

In these cases, the design flexibility justifies the modest NRE required that customization often allows.

However, customizing the Active Matrix LCD itself (size/resolution) can cost restrictive for most applications since the minimum NRE required for panel mask sets is around USD 100k. Unless the scope of the business dictates a customer-owned TFT panel or the project volumes depending on the size, are over 500k pieces per year. In many applications, combining a standard active matrix TFT cell with a custom-designed module and electrical interface offers the most favorable overall cost solution.

  • Designing Custom Modules Extend Lead Time.

The lead time is another consideration for a custom design that can be shorter than you would think. Short lead time is made off-the-shelf LCD modules attractive for designers.

LCD manufacturers like Createxplay can typically design custom housing for passive or active matrix LCDs – with integrated capacitive touch sensor and interface – within one to two weeks of the initial RFQ and then provide sample custom LCD modules 4-5wks after that.

Createxplay also offers customers the option to use off-the-shelf modules as prototypes within their design before the custom display is ready to evaluate other design aspects and perform qualification work (e.g., testing software).

For many implementers, the design freedom and iterative optimization that customization offers are well worth the additional time required to sample custom LCD modules.


2. Advantages of Liquid Crystal Display (LCD) 

There are many advantages of Liquid crystal display that are listed below:

  • The LCD can produce over 60 inches or 150 cm diagonal in large sizes.
  • It has no geometric distortion.
  • It is very compact, thin, and has light CRT displays.
  • Magnetic fields do not affect it.
  • Small heat is emitted during operation due to low power consumption.
  • It is much thinner than a Cathode Ray Tube (CRT) monitor.


3. Customized LCD

Nowadays, different LCDs are used in various applications, from calculators, watches, games to medical and industrial applications. The display content easily modified to satisfy the exact requirements of an application is one of the main advantages of LCDs over all other display technologies. The customized LCD panels can show particular user interface information that enhances the product performance and value.

Customized LCDs display alphanumeric digits, numeric, ON, or OFF indicators, graphic icons, messages, pie charts, bar graphs, symbols, etc. The content of the LCDs panel is limited only by the product designer’s imagination. Many factors should be considered in the design of a customized LCD panel. 

4. Important Information To Design Custom LCD Panel

The following information is necessary to design a quotation for a customized LCD panel:

  • LCD panel, 
  • Display modes, 
  • Polarisers, 
  • Viewing mode, 
  • Backlight requirement, 
  • Operating environment, 
  • Drive method, 
  • Connection method, 
  • A keypad is required if applicable.

5. Advantages Of Custom LCD

  • Custom LCD monitors display static images with full-color detail from computer sources extremely well and no screen burn-in.
  • The number of pixels/square inches on an LCD is typically higher than other display technologies.
  • Custom LCD monitors are good at displaying a large amount of data, e.g., on an Excel spreadsheet with exceptional clarity and precision.
  • Custom LCDs are available in many sizes.
  • They are not affected by increased or decreased air pressure in airplanes.
  • Custom LCD technology is not prone to ghosting or screen burn-in.
  • Custom LCD televisions require less power to operate than a plasma TV.
  • Generally, LCD monitors are better for public display, such as airport and retail store signage, due to the bright room light environment.
  • Portable test equipment
  • Diagnostic device
  • Electric, water, gas meters
  • Telecom products
  • Measuring device
  • Marine equipment
  • Medical equipment
  • Automotive display

6. Disadvantages Of LCDs

  1. They suffer from a motion blur effect.
  2. The high refresh rate of LCD televisions can negatively affect the picture.
  3. LCD technology can change colors slightly as the backlight ages.

7. How Can Createxplay Help?

What Are the Causes of LCD Display Screen Flicker And How To Fix Them?

What Are the Causes-of-LCD-Display-Screen-Flicker


  1. What is Screen Flickering?
  2. CCFL Backlit Display Vs LED-Backlit Display
  3. Top Seven Reasons For LCD Screen Flashing
  4.  Four tips to fix a screen flicker
  5.  Final Words

1. What is Screen Flickering?

Screen flickering is due to changes in brightness that occur when the cathode ray tube projects on the screen while its refresh rate is low. The number of times the display hardware updates its buffers in one second is called the refresh rate. Generally speaking, the variation of brightness mainly occurs between cathode ray tubes.

With a refresh rate below 60 Hz, most screens will produce flicker visible to the naked eye, but a refresh rate between 70-80 Hz can make the screen almost flicker-free. If the refresh rate exceeds 120 Hz, the flicker cannot be seen by the naked eye. We call it flicker-free.

A problem that arises when fluorescent lamps are used on LCDs is that it has a frequency range that is beyond the range of human perception.

The reasons for the LCD Display flashing screen are given below: 

  • shielding coil
  • Signal interference
  • Hardware
  • Refresh frequency setting
  •  Monitor time is too long
  • Too high frequency
  • Similar to the frequency of the light source.

2. CCFL Backlit Display Vs LED-Backlit Display

LCD is divided into two CCFL backlights and an LED backlight. When the LCD display uses a CCFL backlight, the backlight power off, the lamp will continue to emit light for about a few milliseconds. The characteristics of the LED backlight allow it to control the speed of switching on and off the power supply more quickly to avoid continuous lighting when the power is off. Consequently, the LED backlight flashing screen will be more prominent than the CCFL backlight.


3. Top Seven Reasons For LCD Screen Flashing

  • The LCD Display Cable Shielding Coil

The screen will also interfere if the LCD cable has no shielding coil or anti-interference black bump.

  • Strong Electric Field Or Magnetic Field Interference

LCD is easily disturbed by a strong electric field or magnetic field, and sometimes the screen jitter is caused by the magnetic field or electric field near the LCD. To liquid crystal display ruled out clean everything around interference, move the computer to an empty table, then start boot test, if the screen computing phenomenon disappears. It means that your computer where you found it has a strong electric field or magnetic field interference. Please send suspiciously (e.g., speakers of the subwoofer, power transformers, magnetizing cup, etc.) from a computer nearby.

  • LCD Display Hardware Problems

Please turn off the LCD and turn it back on a few times to degaussing. (today’s monitors have automatic degaussing when turned on.) LCD screen flashing reason: LCD screen refresh rate problem & LCD display and video card hardware problems display.

  • Refresh Frequency Setting Of The LCD Display

The main reason for the LCD screen dither is the LCD refresh frequency set lower than 75Hz caused by, at this time, the screen often appear dither, flicker phenomenon, and we only need to put the refresh rate to 75Hz above. The phenomenon of the screen dither will not occur.

  • The Use Of LCD Display Time Is Too Long

Sometimes, because liquid crystal display time is too long, there will be a jitter phenomenon. The faulty display can be connected to someone else’s computer for testing to test whether the electronic components inside the display are old or not. If the fault still appears, the display is broken and repaired.

  • Highest Frequency Of The LCD Display Screen

The frequency of the LCD screen itself is too high, which leads to screen flashing. Generally, a few real-life problems cause screen flashing due to high frequency. People’sPeople’s naked eyes have no flicker feeling for the picture over 60hz, while the design standard of the general LCD screen is basically maintained on this data, so the frequency will not be too high under normal circumstances, but at the same time, the screen itself can not be ruled out fault. After the relevant instrument measurement is indeed the fault of the screen itself, in addition to the replacement of a new monochrome LCD screen is the design of equipment-related software.

  • Similar LCD Display And Light Source Frequency 

LCD and light source frequency close to the situation of the splash screen is very common, because the frequency of the different light sources is different, in certain cases, the frequency of the LCD screen and artificial light similar flicker is also more common, the best way at this time is a kind of artificial light or LCD equipment, avoid the splash screen.

4. Four Tips To Fix A Screen Flicker

1. Check your cables

Check the cable at both the computer and Monitor ends. Try replacing the cable with a new one if tightening or reconnecting it does not fix the problem. If that doesn’t fix the issue, it’s time to investigate something else.

2. Check the monitor refresh rate.

On a Windows 10 PC, you can check the refresh rate by clicking the Windows key typing “refresh rate” into the search field. Clicking “view advanced display Info” and clicking on “Display Adapter Properties For Display 1 “, or that number is causing the display issue.

In the window properties, click the middle tab, titled Monitor, and you will see an area to set the refresh rate.

  1. Check the video card.

A video card that isn’t properly seated on the motherboard can cause many problems, including a screen flicker. Turn the computer off and then open the case, remove the video card and connect the monitor cable to a second video card you have replaced the old one with. If the problem persists, the issue isn’t the card–it’s something else.

  1. Test the Monitor

Inspect the Monitor for physical damage and use the Monitor’sMonitor’s onboard buttons to check for settings that may be causing the issue.


5. Final Words

We have described information gives you the reorganization of the causes of LCD Display screen flicker with their solution.

LCD, although the price is not high, there are various problems. It will have multiple effects on our work and life. In ordinary life, when using LCD, as long as pay attention to the following points will extend the life of LCD.

All the screens flicker when it works. But we don’t see it all the time because it flashes too fast to catch the flickering in our eyes. When the screen’s refresh rate gets slow, we see the screen flickering. The causes behind screen flickering are very common properties. That’s why we always need to keep our device updated and clear the virus from the device to get a flicker less display.


Who Can Challenge Segment LCD? OLED, QLED, or Micro LED



  1. OLED Screens advantages and disadvantages
  2. QLED Living In The Lab with advantages and disadvantages
  3. Expensive Micro LEDs advantages and disadvantages
  4. Advantages of Custom Segment Displays
  5. Who Is The Next Generation Of Display Technology?
  6. Final Words

You almost always think of LCD and OLED only when thinking of display panels. OLED is a technology that is already popular and used in various display devices widely. In addition, MicroLED and QLED have also become the next generation of display technology. But the question is, who can challenge LCD?

  • What are the differences between OLED, QLED, and MicroLED?
  • Who will be the next generation of display technology?
  • Who can challenge LCD?

1. OLED Screens Advantages And Disadvantages

OLED, an organic light-emitting diode, refers to the phenomenon of organic semiconductor materials and light-emitting materials leading to luminescence through carrier injection and composite driven by electric fields. Here are some advantages of OLED screens given below:

Advantages of OLED

  • Spontaneous light is the biggest advantage of OLED or self-luminous OLED televisions that can be made very thin. Even LG has made OLED TVs a stunning 2.57mm thick, with the widest part no thicker than 5mm. 
  • Moreover, OLED can be switched on and off for each pixel because of its spontaneous light of pixels. 
  • It can achieve the partition backlight at the pixel level, which theoretically can acquire indefinite contrast.
  • OLEDs have a wide range of viewing angles and consume less power due to their self-luminous nature.
  • OLED also has a much better color performance with a wider color range.
  • OLED has a special feature produced on flexible substrate materials such as resin and plastic to achieve a soft screen. Curved and foldable phones take advantage of this feature.


    Disadvantages of OLED

    But OLEDs also have a destructive drawback which is given below: 

    1. Organic materials used in OLEDs age faster than inorganic materials used in LCDs. 
    2. A characteristic of OLED displays leaves a residual image when left standing for a long time. 
    3. Although many technologies can help screen burning, they still cannot be solved well.

    2. QLED Advantages And Disadvantages

    QLED is a quantum dot light-emitting diode, having all the advantages of OLED, such as low response speed, spontaneous light, wide color range, etc. 

    Advantages of QLED

    • QLED has longer life as it adopts inorganic quantum dot material.
    • It has no screen burning phenomenon other than OLED organic material.

    Disadvantages of QLED

    • The quantum dots of QDS are susceptible to heat and water; a new manufacturing process needs to be developed as they cannot adopt the same manufacturing process as OLED.
    • QLED Technology has just started for a short time, having limitations such as unstable component life, difficult research, low reliability and efficiency, and difficult development of the solution manufacturing process. 
    • At present, QLED only exists in the laboratory.
    • There is still a certain distance from its commercial use.

    You can ask a question 

    Has Samsung not launched the QLED TV? 

    The answer is that the QLED TV on the market is not QLED in the real sense. The QLED TV can be regarded as an upgraded version of the LCD TV. 

    TV has better picture quality and color performance than traditional LCD TV by adding a layer of quantum dot film in front of the backlight of LCD TV.

    The QLED TV on the market currently is photoluminescence need to rely on the backlight. The real QLED is electroluminescence, which can identify the spontaneous light of pixels.


    3. Expensive Micro LEDs Advantages And Disadvantages

    The Micro LED is the same as the LED light billboard we see on the road, except the Micro LED takes each bead to the micron level. 

    Advantages of Micro LED

    • Micro-LEDs are also pixel-level spontaneous light like OLED. 
    • They reduced traditional inorganic LED arrays, and each LED pixel in the 10-micron size can be addressed and burned individually.
    • Micro LEDs are more efficient and brighter than existing OLED technology but consume less power. 

    Disadvantages of Micro LED

    • The big problem of the micro-LED is that its manufacturing process is difficult.   
    • The most difficult one is “massive transfer technology,” which means how to transfer tens of millions of pixel light sources to the substrate.
    • High production difficulty and low yield lead to the high price of Micro LED. 
    • The current large-size Micro LED TV price is not affordable for ordinary people.

    4. Custom Segment LCD Displays

    LCDs are more affordable under mass production, especially segment LCDs are very high in demand and affordable.

     Advantages of Custom Segment LCD Displays 

    • Low unit cost
    • Low up-front tooling cost. 
    • Estimated tooling Non-Recurring Engineering (NRE) cost for a custom segment LCD can run as low as $900.
    • The one-time NRE fee allows product developers to design and build the display they need for their product within their budget.
    • Add as many varying icons as you need.
    • Low lead times
    • Customize the character height and glass size to meet your requirements.
    • Design support provided
    • Seven, Fourteen, or Sixteen segment options are available.

    5. Who Is The Next Generation Of Display Technology?

    Are LCDs, OLED, QLED, MicroLED the next generation of display technology? 

    The answer is that in terms of performance, if all pixels illuminated spontaneously and did not burn the screen, then quads and micro LEDs would certainly beat OLEDs for longer life. 

    But the picture is different when one views the current state of the art. QLED mass production is far away as it is still laboratory. Micro LED has a high cost, low yield, and no real civilian products currently. 

    OLED screens are generally more expensive than LCDs and are already capable of mass production. LCDs are in mass production, can be customized, and are easily affordable.

    At this stage,

    LCDs are still the next-generation display technology. But soon, OLED could replace LCD if it can lower its price even further. But in the long run, OLED is also a temporary technology, with QLED and Micro LED being the final form until LCDs are the popular technology. 

    There is no need to worry too much about which display technology to use for consumers; all are affordable and easy to use. Even QLED and Micro LED will not overturn the LCD if prices do not fall and if they are commercially available.


    6. Final Words

    The LCDs are still popular display as they are cheap, easy to customize, easy to use, and available at affordable prices. If you still have any confusion, contact us with your query; our expert will answer you as soon as possible.

    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.

    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.
