Saint-Gobain Aand Novaled Announce A Breakthrough For OLEDs

Saint-Gobain and Novaled have demonstrated the feasibility of large area OLEDs, based on a new high-performance metallic anode.

The goal of a two-year research cooperation programme between both partners has been to develop basic technologies for high-performance white OLEDs. Researchers at Saint-Gobain Recherche (SGR), France have created a highly conductive transparent electrode "Silverduct™", bringing up to 10 times better surface conductivity than traditional ITO (Indium Tin Oxide). Thanks to Novaled PIN OLED™technology for high efficiency OLEDs, samples were successfully manufactured on large area surfaces. SGR and Novaled, Germany now see the possibility to produce homogeneous OLED devices up to 100 cm2 which will ease the manufacturing of large OLED lighting products.

Traditional ITO coated glass impedes the race for large area OLEDs, due to its limited ability to carry current over distances longer than a couple of centimetres. Therefore, for large area OLEDs, the ITO layer must be topped with a thick metallic grid to prevent gradient of light emission caused by the sheet resistance of ITO alone (typically 30 Ohm/sq). The new anode Silverduct™ has a sheet resistance of less than 4 Ohm/sq, thus enabling large area OLEDs without additional metal grids. This is an important step especially for transparent and bottom emission OLEDs in which the metal grid is visible. Additionally, by eliminating the metal grid Silverduct™ offers significant potential for reducing manufacturing costs.
