[OLEDp2-1L] Improvement of QD-LED Performance through Reducing Leakage Current via Alleviating Polymer Entanglement of Mixture for Hole Transport Layer
polymer-entanglement, leakage current, QD-LED performance
To take advantages two polymer materials for hole transport layer, it blended in solvent with optimized ratio. However, polymer-entanglement occurs when polymers are dissolved in solvent. It makes the surface rough, which causes leakage current. We introduce to decrease polymer-entanglement. It can decrease leakage current, then improve the QD-LED performance.
