Abstract
Embodiments of the present disclosure provide an organic light emitting transistor comprising: a substrate, and a gate electrode, a gate insulating layer, source/drain electrodes and a light emitting functional layer disposed on the substrate, wherein the organic light emitting transistor further comprises an external electrode coupled to the gate electrode in series, wherein a temperature-dependent resistance change rate of the gate electrode is different from a temperature-dependent resistance change rate of the external electrode.
