Peak current density and brightness from poly(p-phenylenevinylene) based light-emitting diodes

Abstract We report measurements of peak current and brightness from polymer light-emitting diodes based on poly( p -phenylenevinylene). The devices were operated at low duty cycles and supported peak currents in excess of 700 A/cm 2 and produced peak brightnesses of up to 5 Mcd/m2. The values are higher than was previously thought attainable and we discuss them with reference to application in passive matrix displays and polymer laser diodes.
