  1. aVon is the turn-on voltage measured at 1 cd·m−2.
  2. bLmax is the maximum luminance (cd·m−2); CEmax is the maximum current efficiency; PEmax is the maximum power efficiency; EQEmax is the maximum external quantum efficiency.
  3. cthe performance of CE, PE, and EQE at 100 cd·m−2.
  4. dCRI is color-rendering index value.
  5. eCIEs are measured at EQEmax.
