A pixel circuit and a driving method of a display panel and a display device

Embodiments of the present invention provides a pixel circuit and a driving method of a display panel and a display device. The pixel circuit includes a reset module, the data write module, a storage module, and holding the compensation module, and a light emitting device drive module. And reset module and a light emitting device connected to the storage module, configured to reset the storage module and a light emitting device. Data writing module and the drive module connector configured to provide data current. Compensation and holding module and the driving module and a memory module connector configured to generate a control voltage for the driving module, wherein the control voltage is a function of the data based on the current. A storage module connected with the driving module, configured to store the control voltage. Driving module connected to the light emitting device, configured to generate a driving current according to a control voltage. The light emitting device drive current is configured to be driven to emit light. In the pixel circuit may be a light emitting device without increasing the power consumption and improve luminous efficiency.
