一种像素电路、其驱动方法及相关装置
摘要：
本发明公开了一种像素电路、其驱动方法、有机电致发光显示面板及显示装置，包括：数据写入模块、重置模块、第一存储模块、第二存储模块、发光控制模块、驱动晶体管以及发光器件；其中，通过上述五个模块的相互配合，可以使像素电路中的驱动晶体管驱动发光器件发光的工作电流仅与数据信号端的电压和参考信号端的电压有关，而与驱动晶体管的阈值电压无关，可以避免驱动晶体管的阈值电压对流过发光器件的工作电流的影响，从而使驱动发光器件发光的工作电流保持稳定，进而提高显示面板中显示区域画面亮度的均匀性。
摘要（英）：

A pixel circuit, a display panel, a display device, and a method for driving the pixel circuit. The pixel circuit comprises a data write circuit (1), a reset circuit (2), a first storage circuit (3), a second storage circuit (4), a light emitting control circuit (5), a light-emitting device (OLED), and a drive transistor (MO). The data write circuit (1) supplies a data voltage to a first node (N1) in response to a scan signal. The reset circuit (2) supplies a reference voltage (VRef) to a second node (N2) in response to the scan signal. The first storage circuit (3) is connected between the second node (N2) and a third node (N3). The second storage circuit (4) is connected between a first power supply end (VG1) and the third node (N3).
