Optical bonding is the process of applying a transparent adhesive layer between display components – such as a cover lens, PCAP touch sensor, and LCD/TFT display – to create a single, optically unified unit. This eliminates the air gap that can cause internal reflections, reduces glare, and improves contrast and sunlight readability.
We use a variety of high-performance optical glues and adhesives, including silicone, acrylic, and epoxy-based materials, to suit different application environments and substrate requirements.
Our Optical Bonding & Lamination Capabilities
PCAP Touch Sensor Bonding
We specialise in applying and optically bonding PCAP (Projected Capacitive) sensors to front panels made from plastic or glass. This includes:
- Bonding PCAP sensors directly to plastic substrates like our Solaris™ or Soni™ range.
- Creating durable, lightweight alternatives to glass-based touch interfaces.
- Supporting custom aperture cutting and screen-printed components.

TFT / LCD Display Bonding
We offer precision optical bonding of TFT and LCD displays to a variety of cover materials, helping to:
- Improve display durability and impact resistance
- Eliminate condensation or fogging in outdoor and harsh environments
- Reduce parallax and improve user experience in touch applications
Lamination of Specialist Films
We can laminate a wide range of functional and optical enhancement films to plastic or glass substrates, including:
- Reflection control films to reduce ambient glare and improve outdoor readability
- Colour grading filters for camera systems and vision-critical applications
- Anti-glare and anti-reflective layers tailored to your specific lighting conditions
These films can be applied as standalone enhancements or combined with optical bonding processes for a complete display upgrade.
Custom Optical Adhesive Solutions
Our experienced team will help select the right optical adhesive for your application, balancing clarity, thermal expansion and environmental resistance.
Options include:
- Dry bonding (using OCA films)
- Liquid optically clear adhesives (LOCA)
- UV-curing or pressure-sensitive adhesives
Designed for Demanding Environments
All our optical bonding and lamination services are carried out in our controlled environment production facility in the UK. We offer both prototype development and full-scale production, ensuring consistency and high optical standards across every build.
Our solutions are trusted in:
- Rugged industrial touchscreens
- Automotive & marine control systems
- Aerospace display assemblies
- Medical diagnostic equipment
- Public-facing kiosks & digital signage
Multi-Layer / Multi-Stack Optical Assemblies
In addition to single-layer bonding, Panel Graphic offers multi-stack lamination—the precise assembly of multiple functional layers into a single optically bonded unit.
Our in-house team can laminate and align multiple films, substrates, and display components with micron-level accuracy, ensuring optimal optical performance and mechanical stability.
Typical multi-stack configurations may include:
- Anti-Reflection Optical Laminate
- Colour grading or IR filter
- Optically clear adhesive
- Toughened Glass / Hard coated plastics
- Pressure Sensitive Gasket
These complex assemblies are ideal for mission-critical displays used in automotive, aerospace, military, and outdoor environments, where clarity, ruggedness, and reliability are non-negotiable.
Whether you’re building a high-performance HMI interface or need a fully integrated display window, our multi-layer bonding process gives you the flexibility to combine multiple technologies in one seamless unit.
