Technical improvements to improve the feasibility of large-scale OLED manufacturing

Saint-Gobain Recherche (SGR) has developed 1 kinds of highly conductive transparent electrodes, named Silverduct, whose surface conductivity is 10 times higher than that of traditional ITO (Indium Tin Oxide, indium tin oxide).

It is understood that Saint-Gobain and Germany NovaLED high power OLED industry cooperation, and actively develop the basis for efficient white OLED technology.

Thanks to the Novaled PIN OLED technology for efficient OLED, the sample is currently on the surface of a large area of successful production, the future will make the manufacture of large OLED light-emitting products easier.

Conventional ITO coated glass makes it difficult to produce large areas of OLED, because the ability of the coated glass to conduct current is limited to a few centimeters. Therefore, in order to produce a large area of OLED, the ITO layer must be covered with a thick metal mesh to avoid the distortion due to the ITO chip resistance (sheet resistance, usually 30Ohm/sq). The new anode Silverduct sheet resistance is less than 4 Ohm/sq, so it can not produce a large area of metal mesh OLED, in addition to the characteristics of the metal mesh, but also may reduce manufacturing costs.

SGR developed the electrode plus Novaled PIN OLED technology, so that the current production of samples in the laboratory with a performance increase of 30% performance.

In addition, due to the need for the use of metal mesh, the entire process becomes simple, and the life of new products and ITO type OLED equipment compared to enhance the.
