Fig. 3: Electrical and optical characteristics of cavity-optimized OLEDs on textile substrates.

Representative device performance (a) current density-current efficacy curve, b voltage (V)-current density (J) curve, and (c) voltage (V)-luminance (L) curve, all tailored to the cavity peak (623 nm) optimization. d Normalized electroluminescence of the red-colored and textile-based OLEDs.
