Abstract:
A pixel driving circuit, comprises: a line (Data), a first scanning line (Scan1), a second scanning line (Scan2), an enabling control line (Em), a power supply line (S), a light emitting device (D), a driving transistor (DTFT), a storage capacitor (C), a resetting unit (1), a data writing unit (2) and a light emitting control unit (3), and further discloses a pixel driving method, an array substrate and a display apparatus. The pixel driving circuit of the present disclosure solves the problem of non-uniformity of the threshold voltage caused by the manufacturing process and long-time operation of the pixel point driving transistor by means of compensating, so that the current flowing through each pixel point light emitting device is not affected by the threshold voltage, thereby finally ensuring the uniformity of the image display.
