A significant enhancement in power efficiency for alternating current‐driven field‐induced polymer electroluminescent devices is demonstrated by employing a high‐ k ferroelectric polymer dielectric through impedance matching of the device with the driving source. A peak power efficiency of 34.1 lm W –1 at a frequency of 65 kHz is achieved, which is 2 to 12 times higher than the previous highest reports.
