Abstract
There are provided a pixel circuit and a driving method thereof, and a display apparatus. The pixel circuit comprises: a first transistor (T1), a second transistor (T2), a third transistor (T3), a storage capacitor (C1) and a light emitting device (L). A gate of the first transistor (T1) is connected to a first control signal terminal (S1), and a first electrode thereof is connected to a data signal terminal (DATA); a gate of the second transistor (T2) is connected to a second electrode of the first transistor (T1), a first electrode thereof is connected to a second electrode of the third transistor (T3), and a second electrode thereof is connected to a first terminal of the light emitting device (L); a gate of the third transistor (3) is connected to a second control signal terminal (S2), and a first electrode thereof is connected to a first power supply signal terminal (ELVDD); one terminal of the storage capacitor (C1) is connected to the gate of the second transistor (T2), and the other terminal thereof is connected to the second electrode of the second transistor (T2); one terminal of a parasitic capacitor (C2) formed by the light emitting device is connected to the first term…
