Abstract:High-resolution organic light-emitting diode (OLED) displays often suffer from image quality deterioration due to lateral leakage current (LLC). We performed the detection of LLC using operando electric-field-induced doubly resonant sum-frequency generation (EFI-DR-SFG) measurements under conditions where the electric potential, formed by the LLC to an adjacent pixel, was below the emission threshold voltage for the use of OLEDs. The EFI-DR-SFG outputs of the voltage-applied pixel and its adjacent pixel (nonvo… Show more
