Patent number: 10354596Abstract: A pixel circuit and a drive method therefor, and an active matrix organic light-emitting display. The pixel circuit initializes an anode of an organic light-emitting diode (OLED) through a seventh thin-film transistor (M7), so that the aging of the organic light-emitting diode (OLED) is slowed down and the service life of the organic light-emitting diode (OLED) is prolonged. The current output by a first thin-film transistor (M1) serving as a drive element is determined by a data voltage provided by a data line (Dm) and an initialization voltage (Vref) provided by a third power supply and has nothing to do with external supply voltages and a threshold voltage of the first thin-film transistor (M1), and therefore brightness non-uniformity caused by the deviation in the threshold voltage of the thin-film transistor and the change in the supply voltages can be avoided.Type: GrantFiled: December 1, 2015Date of Patent: July 16, 2019Assignee: KUNSHAN GO-VISIONOX OPTO-ELECTRONICS CO., LTD.Inventors: Jiuzhan Zhang, Xiujian Zhu
