Abstract
The pixel circuit of the present disclosure includes: a light emitting module configured to emit light; a driving module configured to drive the light emitting module to emit light according to a driving voltage during a light emitting stage; a storage module configured to maintain and provide the driving voltage to the driving module during the light emitting stage; a first transistor, a first electrode of the first transistor being connected to a position where the driving module receives the driving voltage, and a second electrode of the first transistor being not directly connected to a signal source; a second transistor, a first electrode of the second transistor being connected to the first electrode of the first transistor, wherein a structure to which a second electrode of the second transistor is connected is different from a structure to which the second electrode of the first transistor is connected.
