The invention relates to a drive sensing structure, applicable to an environment of an organic light-emitting display device. The driving sensing structure includes: an organic diode, a driving circuit, a sensing circuit, and a voltage maintaining circuit; wherein, the driving circuit is used to receive a control signal and generate a corresponding voltage signal to drive the organic diode to emit light stably.
