ADVANCED LINK PHOTONICS
A Leading Rugged Display Innovator
Optical Stack Bonding
DryBond and wet (optical) bonding
patented air-gap bonding
ALP uses various bonding approaches to integrate Display Head Assemblies (DHAs), minimizing reflections while enhancing ruggedization. These approaches include our innovative DryBond technology, traditional wet optical bonding, and our patented Total Reflection Control Air-Gap Bonding.
Advantages of DHA with an air gap:
1. Low cost
2. Thinner and lighter design
3. Higher heating efficiency
4. Lower maintenance requirements
5. Improved optical performances
ALP has recommended our air-gap integration to many customers and has manufactured numerous field-deployed Display Head Assemblies (DHAs) delivered worldwide.
ALP/RSP’s DryBond process is a proprietary, in-house developed technology for bonding two rigid substrates. It utilizes pressure-sensitive adhesives (PSAs) as bonding agents, which are resistant to yellowing and validated to withstand a wide operating temperature range.
This technology is used to laminate chemically strengthened 0.3 mm thin glass onto resistive touch panels, , enabling the production of our rugged resistive touch panel gTouch series. The DryBond process is also applied to integrate EMI and heaters into Display Head Assemblies (DHAs).
ALP also offers traditional wet optical bonding services. Our bonding agents, based on acrylamide formulations, and curing processes are developed and optimized to minimize bonding stress. Our bonded assemblies are qualified for avionics and land mobile applications, and have demonstrated long-term stability and durability in high-altitude and high-vibration environments, even after more than ten years in the field. This process is readily applied to integrating touch screens with additional functionalities such as heaters or EMI shielding (ITO or micro mesh).
All services are performed in-house, making ALP a one-stop provider for advanced display solutions.
