Abstract
The present disclosure relates to a pixel circuit and a display device. The pixel circuit includes: a pixel unit including: an operation current generating module including a gate voltage terminal and a drain voltage terminal and adapted to generate an operation current based on a voltage at the gate voltage terminal; and a light-emitting control module connected in series with the operation current generating module and adapted to control whether or not to provide the operation current to a light-emitting device based on a light-emitting control signal; and a driving control circuit, including: a feedback module for receiving a first input voltage and a data current and adapted to provide a feedback loop between the gate voltage terminal and the drain voltage terminal; and a data current module adapted to provide the data current.
