Flexible OLED devices on EXPEEK® film with high-temperature torelance
Technological developmental results: Flexible OLED devices on EXPEEK® film with high-temperature torelance (In cooperation with: KURABO INDUSTRIES LTD.)
OLED fabrication often requires high-temperature processes (higher than 200ºC). From this point of view, we develop high-temperature-tolerant barrier films for flexible OLEDs, using EXPEEK film developed by KURABO.
