Cover Lenses

Cover lenses provide the user-facing surface of a display assembly, protecting the underlying electronics while enhancing usability, durability and product appearance.

GTK manufactures custom cover lenses and fully integrated display assemblies, combining cover glass, touchscreens and TFT displays into a production-ready solution. Assemblies can be supplied fully bonded and tested, helping to simplify integration and reduce assembly complexity.

Cover lenses can be customised to meet specific mechanical, environmental and branding requirements, with options including custom shapes, printed graphics, impact resistance and specialist surface treatments.

As part of our Integrated Manufacturing Services (IMS) approach, we support customers from prototype development through to volume manufacture, delivering complete display and HMI solutions through a single supplier.

impact resistant cover lens

Impact resistant cover lenses

Where displays are exposed to demanding operating environments, cover lenses can be designed to provide enhanced protection against impact, shock and accidental damage.

Available in thicknesses up to 8 mm, cover lenses can be specified to achieve impact resistance ratings of up to IK08, making them suitable for industrial equipment, public access terminals, kiosks and other high-use applications.

  • Strong durability and impact resistance
  • Thicknesses up to 8 mm
  • Impact resistance up to IK08 (5 Joules)

Flexible user interface design

Cover lenses can be used to create intuitive and visually consistent user interfaces that align with your product branding and operational requirements.

Screen printing enables the addition of logos, indicator icons, control zones and decorative elements directly onto the glass surface, helping to create a professional and durable HMI solution.

  • Indicator icons and status graphics
  • Customer branding and logos
  • Touch activation areas and hot buttons
