Abstract
There are provided in the present disclosure a pixel driving circuit, an array substrate and a display apparatus. The pixel driving circuit comprises: a compensation module (11), a control module (12), a driving modeling (13), and a light emitting module (14), wherein: the compensation module (11) is connected to a scan signal (Scan), a data signal (Vdata) and a reference signal (VREF) and further connected to the control module (12) and the drive module (13), and is configured to receive the data signal (Vdata) and the reference signal (VREF) under the control of the scan signal (Scan) and compensate for a threshold voltage of the drive module (13) under the control of the control module (12); the control module (12) is connected to a light emitting control signal (EM) and a power supply signal (ELVDD) and further connected to the drive module (13) and the light emitting module (14), and is configured to receive the power supply signal (ELVDD) under the control of the light emitting control signal (EM) to control the compensation module (11) to compensate for the threshold voltage of the drive module (13); one terminal of the light emitting module (14) is connected to the drive mo…
