Abstract
The present disclosure discloses a pixel circuit and an external compensation method thereof. The external compensation method detects real-time source potentials of a driving transistor through n iterations, a single iterative detection time that can be set artificially to limit a time for each iteration to detect a real-time source potential of the driving transistor, until the real-time source potential of the driving transistor is equal to a target source potential, thereby improving threshold voltage detection efficiency of the driving transistor.
