Extended Data Fig. 6 | Statistics of device performance. a, b, Distributions of
maximum EQE (a) and maximum brightness (b) obtained from 90 QD-LEDs with
double EML. c, Operational lifetimes of QD-LEDs with a double EML consisting
of C/S/S-Cl(l) over C/S/S-Cl(f ) for different initial brightness values. d, Measured
lifetime (T 50 ) of the devices versus brightness. The T 50 value at 100 cd m−2 was
estimated by fitting with the empirical equation LT 0 n×= 50 constant, where L 0 is
the initial brightness and n is the acceleration factor.
