(a) External (closed symbols) and power (open symbols) efficiencies of one- (circles), two- (squares) and three- (triangles) element WSOLEDs as functions of current density. Arrows indicate values at approximate luminances of 1000 and . (b) Voltage vs the number of fluorescent/phosphorescent elements at current densities of 1 (circles), 10 (squares), and 100 (triangles) .
