摘要： A pixel circuit, a method thereof, an electroluminescent panel, and a display device are provided. The pixel circuit includes a first switch sub-circuit, a second switch sub-circuit, a luminescent sub-circuit, and a dual-drive sub-circuit. Through improving the pixel circuit, a first driving terminal of the dual-drive sub-circuit connects to a first node, a second driving terminal of the dual-drive sub-circuit connects to the second node, when a first and a second gate line signal terminal input the gate line scanning signal alternatively, the first and the second switch sub-circuit are working alternatively, cause the first and the second driving terminal are working alternatively, thus to drive the luminescent sub-circuit to emit light. Therefore, the two driving terminals work alternatively to avoid the voltage instability due to threshold voltage shift caused by one driving terminal of the dual-drive sub-circuit works for a long time.
