Abstract
Disclosed are to a pixel circuit, a method for driving the pixel circuit and a display panel. The pixel circuit includes a data write module, a storage module, a drive module and a light emitting device. The drive module includes a first control terminal and a second control terminal. The data write module is configured to write, at a data write stage, a data signal into the first control terminal of the drive module, the storage module is configured to maintain a potential of the first control terminal, the second control terminal is electrically connected to a pulse-width modulation (PWM) signal input terminal of the pixel circuit, and is configured to control the drive module to provide discontinuous drive current according to a PWM signal from the PWM signal input terminal at a light emission stage, and the light emitting device emits light in response to the discontinuous drive current.
