Optical bonding – display system solutions from a single source

With the development of an in-house optical bonding technology DATA MODUL is now capable of providing displays solutions with very high functional, optical and environmental performances.

Optical bonding is the process of adhesive bonding of two or more transparent components using a high-quality optical grade adhesive. By such bonding the air gap between the transparent components is entirely eliminated. This results in enhanced optical performance, especially with respect to readability under direct sunlight use. Additional benefits are increased mechanical strength, reduced sensitivity to humidity, dust and temperature fluctuations, higher durability, and even better functionality for touch sensitive display solutions.



DATA MODUL focuses on the most advanced optical bonding technology using an atmospheric UV curing system with an one component adhesive. Our technology enables high volume, scalable and high performance optical bonding at reasonable costs. The first fully automated bonding equipment is ready to be installed in our new cleanroom and shall be operational beginning 2013. The automated process can be used for bonding various components (e.g. displays, cover glasses, touch sensors, EMI filters etc.) for a wide range of displays solutions and optical components in our market segments.



The unique combination of optical bonding and high quality materials ensures the best performance of our products. An example of such materials that are optically bonded would be the wide variety of covered glasses currently employed in our products. These have improved mechanical properties and/or are surfaced refined with various coatings (anti-reflective, anti-glare, anti-smudge, anti-fingerprint, and combinations), thereby further enhancing the optical performance of our products.



Customers are invited to experience the improved characteristics of the new optically bonded products. DATA MODUL is looking forward to facing new technical challenges, thereby remaining, as always, a front runner in its business.



Examples of optical bonding applications and the added value to our products are:



Bonding displays to cover glasses



•improved readability through lowering reflectance, increasing contrast and brightness

•avoidance of Newton rings

•improved mechanical strength and durability (scratch resistance, vandal proof, resistance to humidity, dust, temperature fluctuations)

•improved heat dissipation through direct contact





Bonding touch sensors to displays and/or cover glasses

•improved heat dissipation through direct contact

•improved functionality

•no dust and condensate between sensor and cover
