Samsung to develop thinner QD-OLED

According to Korean media Thelec, Samsung Display recently launched a research and development project to reduce the number of glass substrates used in QD-OLED panels from 2 to 1. The project is mainly to develop thinner quantum dots (QD) - Organic Light Emitting Diode (OLED) panels.

Samsung Display's QD-OLED panels, which have been mass-produced since the end of last year, require the use of two glass substrates, including a glass substrate for thin film transistors (TFT) and a glass substrate for QD color conversion layers.

The new project will change the process flow of the QD color conversion layer. In this project, Samsung Display will develop a technology that allows the QD color conversion layer to be inkjet printed on top of a blue OLED encapsulation layer instead of a glass substrate as it currently is, and then encapsulated with the QD color conversion layer. craft. Encapsulation refers to the process of protecting organics from moisture and oxidation. Although the process of encapsulating the blue OLED and the QD color conversion layer separately is the same as the current process, the difference is that the glass substrate for the QD color conversion layer is eliminated.

After the successful development of this project by Samsung Display, it is expected to reduce the material cost, simplify the production process, and is expected to realize the Rollable (rollable) function design.
