(a) Schematic architecture of OLED device used in the present study. (b) Relationship of terminal voltage and current density (circles), and current efficiency (squares) on OLED devices. (c) Time-efficiency plot of OLED devices on constant current mode maintaining the initial current density. The initial current density was corresponding to 1000 cd m−2 of the emission intensity. The simulated lines, green for and yellow for T2-6970 and D3, respectively, were calculated from the fitting of the time-dependent degradation model34.
