Abstract
The present application discloses a pixel circuit, including a data-input sub-circuit configured to apply a data voltage from the data line to a first node; a reset sub-circuit configured to reset the second node; a driving-control sub-circuit coupled to a first power supply, the first node, and the second node; a power-storage sub-circuit configured to regulate a voltage difference between the first node and the second node; a light-emitting device coupled to the second node and a second power supply; and a sampling sub-circuit coupled to the data line and the second node and being configured to control the data line to connect with the second node for collecting a voltage signal containing information about electrical properties of the driving-control sub-circuit and being used to generating a compensation voltage for compensating any drifts of the electrical properties.
