PIXEL CIRCUIT, DISPLAY DEVICE, AND DRIVE METHOD THEREFOR

摘要

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 (C1), a first transistor (T1), a second transistor (T2), and a third transistor (T3), the first transistor (T1) being used for compensating a threshold voltage of the third transistor (T3). The drive method for the pixel circuit drives the pixel circuit to emit light by applying scanning signals to the pixel circuit on scanning lines (Sn1, Sn2, Sn3) in sequence. The pixel circuit and the drive method therefor can improve the response characteristics of active matrix organic light-emitting diodes, thereby enabling the display device to display images having uniform image quality.
