Alternating Current Driven Green Transparent Organic Light-emitting Devices增强出版
Direct current driven green transparent organic light-emitting device utilizing transparent Mg:Ag cathode was fabricated. Then
novel device structure employing transparent Mg:Ag interconnecting layer to connect two light-emitting units was proposed to realize alternating current driven green transparent organic light-emitting device(AC-TOLED). The spectra of AC-TOLED were almost identical in the direction of light output on indium tin oxide(ITO) and Mg:Ag sides. The maximum brightness was 1 374 cd/m
2
and 283 cd/m
2
respectively. And the maximum efficiency was 26.1 cd/A(8.1 lm/W) and 3.5 cd/A(1.7 lm/W)
respectively. The higher performance of ITO side was caused by the different transmission of ITO electrode and Mg:Ag interconnecting layer. Under low frequency alternating current
the two light-emitting units of AC-TOLED emitted green light alternately. However
the two light-emitting units of AC-TOLED emitted green light simultaneously for human eyes under high frequency alternating current
because human eyes cannot distinguish the flicker of each unit during alternative emission.
