像素电路及其驱动方法、显示面板和显示装置
摘要：
本发明提供了一种像素电路及其驱动方法、显示面板和显示装置，像素电路中：驱动晶体管的源极与漏极中的一个连接控制电压线，另一个连接发光器件；存储电容的第一端连接驱动晶体管的栅极，第二端连接控制电压线；导通单元的第一端连接扫描线，第二端连接数据线，第三端连接寻址单元的第一端，第四端连接公共端，用于在第一端处为第一电平时导通第二端与第三端，在第一端处为第二电平时导通第三端与第四端；寻址单元的第二端连接数据线，第三端连接存储电容的第一端，用于在第一端处为有效电平时导通第二端与第三端。本发明可以解决扫描信号的输入位置处的输入阻抗不够大时扫描信号在传输过程中的幅值损失问题。
摘要（英）：

The invention provides a pixel circuit and a driving method thereof, a display panel and a display device. In the pixel circuit, one of the source and the drain of a driving transistor is connected with a control voltage line, and the other is connected with a light emitting device; a first end of a storage capacitor is connected with the gate of the driving transistor, and a second end is connected with the control voltage line; a first end of a conduction unit is connected with a scanning line, a second end is connected with a data line, a third end is connected with a first end of an addressing unit, a fourth end is connected with a common end, the second end and the third end are conducted when the first end is at a first level, and the third end and the fourth end are conducted when the first end is at a second level; and a second end of the addressing unit is connected with the data line, a third end is connected with the first end of the storage capacitor, and the second end and the third end are conducted when the first end is at an effective level. The problem about amplitude loss of a scanning signal in the transmission process when the input impedance at an input position of the scanning signal is not high enough can be solved.
