Holst Centre, Plextronics join forces to drive OLED lighting
With its expertise in several of the functional materials needed to develop OLEDs, Plextronics complements the Holst Centre’s existing partners. The Plextronics-Holst partnership’s goal is to improve the scaling of lab device performance to large area OLED lighting and signage devices. This is game-changing technology that opens the door to many possible lighting applications in living and working environments.
An OLED device consists of a light-emitting material in between conductive and protective layers. In order to maximize the electrical current running through these layers, hole injection and hole transport layers are needed between the anode and the light-emitting material. For low-cost processing on flexible substrates, the materials to deposit these layers need to be compatible with solution-based roll-to-roll processing.
Plextronics is said to be a leader in the discovery, development and manufacturing of solution-based hole-injection layers and hole-transport layers. It will make its current Plexcore hole injection and hole transport inks available within the Holst Centre research program and in return can benefit from the research results for further optimization.
Holst Centre will use the Plexcore inks in its shared research program on Flexible OLED Lighting and Signage to create functional OLED demonstrators, facilitating their characterization and evaluation as it would be applied in a production environment.
According to Ton van Mol, Program Manager Flexible OLED Lighting and Signage at Holst Centre, it is a "major asset" for Holst’s research program having Plextronics on board is. The company’s specific knowledge complements Holst Centre’s expertise in the program.
Plextronics will apply the knowledge gained from this work to enhance its Plexcore hole injection and hole transport products currently used in large area hybrid lighting panel manufacturing as well as in solutions processed manufacturing applications under development, the company explained.
