Heraeus Electronic Materials Division showcased advanced materials for OLED, LED and touch display technologies at the LED/OLED Lighting Japan Exhibition and Conference.
The new Electronic Materials Division has already provided customer benefits, for example by using low curing temperature Heraeus silver resinate to print metal bus bar grids then planarized with Clevios PEDOT conductive polymers to produce low cost printable transparent electrodes for OLED Lighting applications.
“The public”s appetite for display devices sees no limits,” said Dr. Stephan Kirchmeyer, head of the newly formed Business Unit Displays and Semiconductors at Heraeus. “Clevios PEDOT and silver materials are key components in moving towards more economic and sustainable basis for touch technologies. OLEDs provide the ultimate viewing display. Heraeus can provide producers with a ‘one-stop’ solution for multiple layers of the device. With synergies providing superior performance and potentially lower manufacturing cost, Heraeus Electronic Materials now provides a technical choice for OLED and touch panel manufacturers that was unthinkable five years ago.”
At Lighting Japan 2014, Heraeus spotlighted the newly developed Clevios HIL-E materials that in one layer provide both the function as a transparent conductive planarization layer and HIL (hole-injection layer) properties. This approach allows a simplification of the OLED stack and reduction of manufacturing complexity of the OLED, supporting the urgent need to reduce costs of OLED Lighting products to make them competitive in the general lighting market.
The Clevios product range also includes the established highly conductive PH1000 and the development material Clevios HY1, providing sheet resistivity up to 50 Ohm/Sq.. Both materials are practical alternatives to existing transparent conductive oxides, especially indium tin oxide (ITO), as they are transparent, printable and economical in use.
The unique properties of silver resinates include conductivity very near to bulk silver combined with very low surface roughness. These properties allow completely new applications, as very thin lines in the nm range to highly conductive narrow tracks can now be printed. Application methods are by traditional screen or sophisticated emerging technologies such as gravure offset printing.
