Characteristics of cover glass across different applications

Cover Glass are extensively utilized across various industries. While each field has specific requirements concerning materials, thickness, and surface treatments, there are shared features in the core attributes demanded of these components. As a critical element of touch screens, irrespective of industrial changes, the fundamental requirements for cover lens consistently center on safety, durability, environmental adaptability, and aesthetics to ensure stable device performance in diverse application scenarios.

Drawing from practical cases, we have compiled the shared characteristics of glass covers across different industries for your reference.

**In medical industry**

For example,like dental equipment and healthcare inspection devices, the demands placed on glass covers are stringent, impacting both the operational experience of medical personnel and the precision of data readings.
Materials: High-alumina-silica glass, such as Corning Gorilla Glass and Panda Glass, are frequently used due to their high light transmittance exceeding 92%, ensuring clear imagery and true color representation.
After chemical strengthening, the glass can be achieved a compressive stress (CS) greater than 650 MPa, depth of layer (DOL) over 40 µm, and a surface hardness of 9H, effectively mitigating daily impacts and ensuring long-term stable operation.
Thickness: Options include 0.55mm, 0.7mm, 1.1mm, and 2.0mm, balancing thinness with durability.
Shape: Given that most original materials were acrylic and irregularly shaped with holes and slots, cover glass can retain these shapes to fit existing equipment structures and minimize modification costs.
Surface treatment: To accommodate frequent cleaning, the glass surface is typically coated with an anti-fingerprint layer to enhance cleaning efficiency.

**In the financial sector**

encompassing bank ATMs and self-service terminals, these devices are operated in public environments, enduring high-frequency usage and potential violent damage.
Thickness: High-strength glass with a minimum thickness of 3.0mm is generally selected to enhance impact resistance.
Surface treatment: For outdoor applications, the glass surface undergoes AG anti-glare treatment to reduce strong light reflection, improving readability in sunlight and enhancing user experience.

**Smart Home automation**- Air Conditioner Controllers, Smart Door Locks, etc.

Smart home products prioritize aesthetics, slim profiles, and customization. The front glass cover must seamlessly integrate practicality with a refined design sensibility.

Materials: Primarily high-alumina-silica glass such as Corning Gorilla Glass and Panda Glass is utilized to ensure both strength and light transmittance.

Thickness: Ultra-thin glass ranging from 0.5mm to 1.0mm is employed to fulfill the demands of a sleek design.

Appearance Design: An all-black or all-white concealed effect is implemented to present a minimalist style when the screen is off, thereby enhancing overall visual appeal.

**Outdoor Equipment** - Agricultural Machinery, Engineering Vehicles, Aviation and Navigation, Transportation Equipment, etc.

Outdoor equipment must be capable of withstanding complex environmental conditions including extreme temperatures and humidity levels; thus, the cover glass is required to possess exceptional weather resistance.

Thickness: Typically thicker glass of 2.0mm or more is used to elevate protection levels and enhance durability.

Surface Treatment:For outdoor applications, an anti-glare (AG) treatment is essential to ensure readability under intense lighting conditions.

Ink: Anti-UV, high-temperature resistant ink that also exhibits corrosion resistance is employed to guarantee that markings and display information remain clear and legible in harsh environments.

**New Energy - Charging Station**

Charging Station are subjected to prolonged exposure outdoors and must endure wind, sunlight, rain erosion, snow accumulation as well as potential accidental impacts.

Thickness: High-strength glass with thicknesses ranging from 3.0mm to 4.0mm has been selected for its enhanced impact resistance which safeguards internal electronic components.

Ink: UV-resistant and weatherproof ink is utilized in order to prevent fading or blurring of markings due to sun exposure while ensuring long-term clarity remains intact.
