Abstract
A pixel circuit and a display device are provided. The pixel circuit includes a pixel unit which includes an operating current generating module and a light emission control module. The operating current generating module has a gate voltage terminal and is configured to generate an operating current according to a voltage of the gate voltage terminal. The light emission control module is connected in series with the operating current generating module and configured to control whether to provide the operating current to a light emitting device according to a light emission control signal. The driving control circuit includes: a data current module, configured to provide a data current and to input the data current to the gate voltage terminal; and a current adjusting module, configured to control whether to input a compensation current to the gate voltage terminal according to a current value of the operating current.
