Abstract
Disclosed are a pixel circuit, a method for driving the same, a display panel, and a display device, and in the pixel circuit, a node reset sub-circuit resets a gate of a driver transistor in a first reset stage, a data writing sub-circuit writes a data signal, and compensates for drifting threshold voltage of the driver transistor, in a data writing stage, and a light-emission control sub-circuit connects a first voltage terminal with a light-emitting diode in a light emission stage.
