摘要： A pixel circuit and a driving method thereof, an array substrate including the pixel circuit and a display apparatus thereof are provided. The pixel circuit comprising a display driving sub-circuit (200) and a touch detection sub-circuit (210), wherein the display driving sub-circuit (200) is configured to drive a display element to emit light under controls of the first scan line (SCAN1), the second scan line (SCAN2), the third scan line (SCAN3), the data line (DATA) and the light emitting control line (EM); and the touch detection sub-circuit (210) is configured to detect a touch action and generate a sense signal under controls of the second scan line (SCAN2), the third scan line (SCAN3) and the data line (DATA). The effect due to variances in a threshold voltages of driving thin film transistors can be eliminated by compensation, and an integration of a touch function and an AMOLED is achieved.
