PIXEL CIRCUIT AND DRIVE METHOD THEREFOR, AND DISPLAY DEVICE

摘要

A pixel circuit and a drive method therefor, and a display device. The pixel circuit comprises a drive transistor (DT) and a first energy storage element (C1), wherein a source electrode of the drive transistor (DT) is connected to a first end (a) of the energy storage element (C1). The pixel circuit further comprises a drive module and is provided with a reset voltage input end (Reset), a data voltage input end (Data), a working voltage input end (Vdd) and a plurality of control signal input ends (S1, S2, S3, S4). By means of the pixel circuit, a drive circuit flowing through an electroluminescent unit (OLED) cannot be influenced by a start-up threshold value of the corresponding drive transistor (DT), so that the problem of non-uniform brightness of the display caused by drifting of the start-up threshold value of the drive transistor (DT) is completely solved.
