PIXEL DRIVE CIRCUIT, ARRAY SUBSTRATE AND DISPLAY DEVICE

摘要

A pixel drive circuit, an array substrate and a display device. The pixel circuit comprises: a compensation module (11), a control module (12), a drive module (13) and a light-emitting module (14). The compensation module (11) is connected to a scan signal (Scan), a data signal (Vdata) and a reference signal (VREF). The compensation module (11) is also connected to the control module (12) and the drive module (13), for receiving the data signal (Vdata) and the reference signal (VREF) under the control of the scan signal (Scan) and for compensating 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 signal (ELVDD). The control module (12) is also connected to the drive module (13) and the light-emitting module (14), for receiving the power signal (ELVDD) and controlling the compensation module (11) to compensate the threshold voltage of the drive module (13), under the control of the light-emitting control signal (EM). One end of the light-emitting module (14) is connected to the drive module (13), and the other end is connected to the ground (VSS). The drive module (13) drives the light-emitting module (14) to emit light under the control of the control module (12). The pixel drive circuit can avoid the situation of non-uniform brightness of a display device, thereby enhancing the display effect of the display device.
