According to the latest report, Samsung Display has started developing thinner quantum dot (QD)-OLED panels. The aim is to reduce the use of glass substrates from the current two layers to one, the sources said. If Samsung’s display panels are successful, the new version of QD-OLED will also be rollable, they said.

Moreover, Samsung Display’s first commercial QD-OLED panel, which began production late last year, has a glass substrate for thin-film transistors (TFTs) and another for the QD color-conversion layer.
The current iteration of the QD-OLED panel consists of the following layers from the bottom: glass substrate TFT, anode, emission layer, cathode, blue OLED encapsulation, filter, QD color conversion layer encapsulation, QD color conversion layer, QD color conversion layer glass substrate.
According to reports, Samsung Display’s new project aims to remove the top QD color conversion layer glass substrate. The company’s goal is to inkjet print on blue OLED packages, and then complete the QD color conversion packaging process on top of it.
If successful, Samsung Display will be able to save material costs and simplify the production process of QD-OLED panels. The production process for Samsung Display’s QD-OLED panels is currently considered more complicated than that of rival LG Display’s white OLED panels, the sources said.
Furthermore, Samsung Display could remove more than just the QD color-converting layer glass substrate. The report pointed out that QD-OLED panels are expected to be used by Samsung and Sony in their TV products this year. In addition, Dell has also introduced a monitor that uses this panel.
