OLEDs are nowadays facing the same issues they had since the beginning: basically, OLED materials are extremely sensitive to oxidizing agents and, especially, to moisture. This requires encapsulation materials with exceptionally high barrier properties and active fillers or getters, capable of absorbing water on a single molecule basis. The optimization of many functional properties in single encapsulating materials is a very complex materials science problem. The fact that OLED materials can also be very sensitive to heat or radiations, generates many process constraints as well.
It turns out that encapsulation materials must be specifically engineered taking into account the OLED structure, the device architecture, the chemical and physical nature of the materials and, nevertheless, the specific processes to be applied.
SAES provides a very large portfolio of active edge sealants, active transparent fillers, dispensable getters. These products come as the result of its deep know-how in Functional Polymer Composites, and they are specially tailored to address customers’ specific OLED designs and processes.
Leveraging on its Functional Polymer Composite technology and its worldwide collaborations with other material companies and specialized equipment makers, SAES has been able to develop solventless formulations, with water absorption capacities exceeding 13 percent in weight and very high flexibility and adhesiveness for fully bendable devices.
In February, SAES Group will attend the 2nd OLED KOREA Conference in Seoul and the 15th Flex Conference in Monterey with two talks focused on our latest developments in the Advanced Functional Composites for flexible electronics encapsulation.
