Heraeus and ITRI announce improvements in touch screen production

New stable industrial process for mass manufacturing using Clevios based films for touch screens and sensors improve manufacturing efficiency, and lower costs

23 Nov 2015 | Editor

Heraeus in collaboration with the Industrial Technology Research Institute (ITRI) has developed an improved mass-manufacturing process for its Clevios based films used in touch panels and sensors for a variety of electronics devices. This process will enable companies to use Clevios based films to produce touch screens with greater functionality - be flexible, curved, three-dimensional or wearable.

The research of Heraeus and ITRI encompassed its Clevios PEDOT conductive polymer coated films (provided by EOC/Nanya Plastics and Eternal Materials) to fully functional seven-inch touch panels.

Optimum parameter sets with wide process windows were determined for all processing steps of sensor patterning, silver trace printing, FPC bonding, and touch sensor film lamination. Process run cards and quality control steps were implemented and statistical analysis performed to characterize the process. The seven-inch touch panels produced were fully functional, performed five-point multi-touch and pilot production suggesting high yields.

Also, a new fine-line low temperature silver paste "LT Silver P" optimised for Clevios touch sensors was used for the silver trace screen-printing.

Dr. Janglin Chen, Vice President of ITRI & General Director of ITRI’s Display Technology Center, said, "After presenting the world-first foldable 7” Clevios touch panel integrated with a flexible AMOLED Display at Touch Taiwan in August, this is another milestone of our successful cooperation with Heraeus in the field of conductive polymer touch panel technology."
Dr. Ralf Droste, Head of Business Line Display & Semiconductor of Heraeus, said, "The new stable manufacturing process will provide immediate and long-term benefits for touch panel companies, from lower costs to the ability to incorporate greater features and functionality." Ralf, added, "We’ve developed a clear roadmap to enable companies to quickly implement Clevios technology into their manufacturing processes. It allows companies to offer the next generation of foldable touch devices, where Clevios exceeds the performance and functionality of all other transparent conductors."
