Abstract
A pixel circuit, a display device, and a drive method therefor. The pixel circuit comprises: a first power source (ELVDD), a second power source (ELVSS), an organic light-emitting diode (OLED), a first capacitor (C), a first transistor (T), a second transistor (T), and a third transistor (T), wherein the first transistor (T) is configured to compensate a threshold voltage of the third transistor (T). According to the drive method, the pixel circuit is driven to emit light by sequentially applying scanning signals to the pixel circuit on scanning lines (Sn, Sn, Sn). The pixel circuit and the method for driving the pixel circuit can improve the response characteristics of active matrix organic light-emitting diodes, thereby enabling the display device to display images having uniform image quality.
