Heraeus and ITRI demonstrate new flexible technologies for touch panels and displays

Electronic materials play a key role in touch panel technologies, such as new flexible touch technologies, application know-how plays a vital part in the success of the new material to be used in device manufacture

ITRI together with Heraeus have demonstrated the integration of conductive polymer based touch panel with AMOLED technology in a highly flexible device. In the project a 7 inch flexible touch panel / AMOLED device was produced. The device was prepared using Clevios PEDOT conductive polymer material (formulated by EOC, Taiwan) patterned on ITRI’s FlexUp substrate. Solution processable and printable Clevios PEDOT:PSS is used as the transparent electrode in this device.

The touch sensor electrodes are based on a Clevios PEDOT. ITRI subsequently patterned the film using Heraeus invisible etch technology. A key element is flexibility which was tested 10,000 times at a bending radius of 5 mm. The touch panel is laminated on the AMOLED display. The final product has 5 interactive functions within the display including touch controllable zoom in/out and rotation functions.

According to the announcement Heraeus has been collaborating with ITRI since 2013. Further projects with the ITRI Group and Heraeus in the application of displays are ongoing.

The demonstrator will be on show at Touch Taiwan Exhibition, August 26-28 2015.

Dr. Stephan Kirchmeyer, Global Marketing Director for the Display & Semiconductor Business at Heraeus, said, "In this latest development project with ITRI, we have produced a reliable, flexible, advanced touch panel and integrated it with an AM OLED display, opening up new possibilities in flexible, foldable and wearable technologies."
Dr. Janglin Chen, Vice President and General Director of ITRI’s Display Technology Center added, "The co-operation with Heraeus has shown the options for touch panel makers are broader than just metallic based ITO-alternatives."

PEDOT:PSS

The Clevios PEDOT:PSS range from the Display & Semiconductor Business Unit of Heraeus consists of materials for antistatic through to highly conductive applications. Materials are modified for their application method, usually printing or coating, and for their end application requirements. Typically Clevios coatings can reach 100 -250 Ohm/sq. at a transparency of 90% (excluding substrate film). Clevios is increasingly finding applications in touch panels and sensors, as well as OLEDs, organic solar cells and security coatings.
