We
propose an embedded reverse-offset printing (EROP) method, which
generates silver nanowire (AgNW) transparent electrodes for display
applications. The proposed EROP method can solve the two critical
issues of microscale pattern formation and surface planarization.
The AgNW electrode had a transmittance of 82% at 550 nm, a sheet resistance
of 12.2 Ω/sq, and a 3.27 nm smooth surface. We realized the
roll-based pattern formation of AgNW on a plastic substrate as small
as 10 μm with negligible step differences to facilitate the
proposed method. The proposed EROP method also produced a double-stacked
AgNW electrode, enabling the simultaneous operation of separately
micropatterned devices. To verify the usefulness of EROP, we fabricated
an organic light-emitting diode (OLED) device to demonstrate leakage
current reduction and efficiency improvement compared with a conventional
indium tin oxide (ITO)-based OLED device. The EROP-based OLED showed
38 and 25% higher current efficiencies than an insulator-patterned
AgNW OLED and a conventional ITO-based OLED, respectively.
