Scatter Plot from Scientific Research

Operational lifetime (LT50) versus initialLrms. The dotted lines represent linear fits to log(LT50) versus log(Lrms). Black and red lines and symbols correspond to the conventional ECLD and ex-ECLD, respectively. In (e) to (i), the devices were driven using a sinusoidal signal with a frequency of 300 Hz. The different ratio between the brightness of the conventional ECLD and the ex-ECLD in the frequency and voltage scans is attributed to different degradation of the two devices during the scans.
