1. What Are Cover Glass Designs?

Your LCD design must prioritize coverglass protection if your industrial LCD faces harsh environmental conditions. Coverglass provides resistance to scratches and abrasions, increases optical clarity, and supports touchscreen functionality. Our displays offer a variety of coverglass substrates for upgrade or replacement. Createxplay helps you choose the best option based on your application need with varying characteristics between coverglass options. 

Replacing your LCD cover glass with a display provides you with an opportunity to enhance LCD protection and clarity without breaking your budget. We use name-brand materials with low MOQs and competitive pricing to meet all your project goals. We Optimize your coverglass repair with various optical coatings to minimize refraction and reflection, increase protection, and offer perfect surface finishes for your application.  

LCD bonding is one of the diverse adhesive options available on the market. We use LCD bonding as our primary integration to install the cover glass to add protection from water dirt, prevent coverglass shattering, and increase optical clarity.

2. Value Added Options

It’s time to take your cover glass integration one step further by adding a touch sensor to your LCD design. If your LCD does not have touch screen capability, our displays offer virtually limitless touch sensor options for integration with your cover 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. 

Benefits:

  • 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.
  • Customizable professional LCD screen printing 
  • Three bonding methods are available: optical, OCA, and tape.
  • Bond your cover glass with a touch sensor.

5. Cover Glass Features:

  • Chemically-Strengthened
  • Improved Surface Quality
  • Scratch and Crack Resistant
  • Enhanced Response
  • Thin and Light without Fragility
  • Protection From EMI Interference 
  • Promote Sunlight Readability
  • Ruggedized

6. Cover Glass Options

  • Chemically-Strengthened Soda Lime 

Chemical strengthening is ideal for soda-lime sheets under 3 mm. It is used for thin, rugged displays and, depending on the application, it can be strengthened from 8 to 16 hours. Displays offer various soda-lime options: low iron, clear & tinted, anti-glare, and heat-absorbing float glass.

  • Clear and Tinted

This option offers a high light transmission with the opportunity to add AR coating for extra transmission and chemical strengthening.

  • Grey Glass

This glass is tined and used to restrict or reduce light transmission. Benefits include increased privacy, reduced glare, and has a reduced opacity. 

LCD-Cover-Glass-Options
  • Low Iron Soda-Lime

This option offers a high light transmission with the opportunity to add AR coating for extra transmission; this material is eligible for chemical strengthening and features good flatness with no green tint. 

  • Anti-Glare Reducing Etched Soda-Lime 

This glass offers glare reduction with a high resolution, superior durability, and an anti-Newton ring. 

  • 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.
