Introducing DOW Chemical, Inkjet OCR for Foldable OLED [2022 Second Half OLED Seminar]
At the “2022 Second Half OLED Seminar” held at the FKI Hall in Yeouido on November 9, 2022, Dow Chemical introduced silicon-based inkjet printable OCR that can be used for foldable OLEDs.
In general, OCR is mainly used for rigid OLEDs and OCA is mainly used for flexible OLEDs and foldable OLEDs, but recently, OCA is used for rigid OLEDs with hole design, and development to use OCR for foldable OLEDs is also underway.
DOW Chemical said OCR may not have a smooth shape near the edge and its characteristics depend a lot on the substrate, but replacing OCA with OCR can reduce the process and expand productivity.
In addition, it was mentioned that it is possible to form a thin film of 10 um through amount control, and that it has the advantage of overcoming the difficult step with OCA.

Acrylic series are widely used as materials for OCA, which is currently used for flexible OLEDs and foldable OLEDs that are currently on the market.
DOW Chemical finished its presentation with the expectation that silicon-based OCR will be wider in the future because it can maintain reliability even in extreme environments due to low viscosity or characteristic changes despite temperature changes.
