Different Glass Types


By incorporating a special optical coating into our screens, we can transform any display into an interactive mirror. This works by balancing light between the outside of the glass and the inside of the screen. When light on the screen is switched off, it will look like a standard mirror. Different levels of mirrored coatings are available depending on the amount of reflectivity required together with the viewability of the underlying display.


Touchscreens made from untreated, plain glass will reflect sunlight and strong overhead lighting that can impair the readability of the underlying display, unless a high bright LCD is used. Our anti-reflective (AR) coated glass reduces light reflection by around 75% making it perfect for brightly lit environments while maximising image clarity and crispness.


Direct sunlight can cause glare from any screen, dissuading users from interacting with your product. We can produce touchscreen panels that use chemically-etched anti-glare (AG) glass that diffuses light reflected from the front surface and provides a cost effective method of enabling the user to view information on the display, minimising glare. The slightly matt surface of AG glass also has the added benefit of improving fingers ‘glide’ over the touchscreen – sometimes referred to low ‘stiction’, enhancing user experience on applications where lots of dynamic touchscreen interaction is required.

Low Iron

Standard glass contains a small amount of Iron. This gives it a greenish hue which can be especially visible when looking at the glass edge or through a very thick sheet. Low Iron glass (also sometimes called ‘water white’ glass) is made using carefully selected raw materials to minimise this tinting effect, making it ideal for when transparency and purity of image colour are required when looking through the touch sensor. This allows for a truer representation of the system designer’s vision, ensuring that the colours displayed on the underlying LCD, or any printed borders/logos in the touchscreen are faithfully represented.


With the addition of Corning’s Antimicrobial Gorilla® Glass or other types of coated glass, we can help prevent the spread of stain and odour-causing bacteria on touchscreens. Antimicrobial Gorilla glass contains an ionic silver component which serves as an agent that greatly reduces the ability of bacteria to proliferate over time and helps to keep the glass clean. We can produce touch sensors using these glass types, or laminate the material as an additional protective layer onto the front surface of a touchscreen.
