Samsung Display was developing quantum dot (QD)-OLED panels that were thinner than its current commercialized version.
This was confirmed by the booth of the Electronics and Telecommunications Research Institute during the 22nd International Meeting of Information Display (IMID 2022) held at Busan, South Korea.
ETRI said Samsung Display was working on a QD-OLED panel that removes one of the two glass substrates.
The South Korean display maker currently uses two glass substrates on its QD-OLED panel __ one for the thin-film transistors (TFT) and another for the QD color conversion layer.
ETRI called the new technology Samsung Display was developing stacked QD-OLED, where the QD color conversion layer is printed directly above the emission layer stacked on top of the TFT glass substrate.
ETRI confirmed that it was co-developing the technology with Samsung Display with other suppliers and universities.
Removing the substrate will allow Samsung Display to reduce production costs and also make their QD-OLED panel rollable.
However, the technology will likely be commercialized sometime after 2024.
