L max is the maximum luminance observed from device, CE is the current efficiency, PE is the power conversion efficiency, t 1/2 is the time taken for the device luminance to fall to half the maximum value, λ EL is the electroluminescence emission maximum, CRI is the color rendering index value of the device
