The present disclosure discloses a pixel circuit and a display panel. The pixel circuit includes a light emitting module and a driving module including at least two driving units connected in parallel. a quantity of displayable gray scales can be improved or increased by configuring at least two driving units connected in parallel in the driving module where the at least two driving units can each correspondingly configure a light emitting current so that a plurality of light emitting brightness of the light emitting module can be implemented by a sum of these light emitting currents.
