[OLED2-1 (Invited)] All Inkjet-printed Cadmium-Free Electroluminescent-Quantum Dot Display at 217 ppi Resolution
Quantum dot light-emitting diodes, Cadmium-free, Ink formulation, Top emission, Ink-jet printing
We demonstrate the world's first all-inkjet-printed Cd-free EL-QD display by successfully overcoming the fabrication- and performance-limiting factors in solution processing. In particular, the intermixing between the stacked layers within the device was eliminated. A study on the critical factors affecting the device performance, including the influence of ETL solvent on quantum dot, is also discussed in detail.
