摘要： Disclosed are a pixel circuit and a driving method thereof, an array substrate and a display apparatus. The pixel circuit includes a pixel sub-circuit. The pixel sub-circuit includes a first adjusting circuit and a second adjusting circuit. The first adjusting circuit is configured to receive a first data signal and a light emitting control signal to control a magnitude of a driving current used for driving a light emitting element to emit light; the second adjusting circuit is configured to receive a second data signal and a time control signal to control a time duration in which the driving current is applied to the light emitting element; and the time control signal changes within a time period during which the light emitting control signal allows the driving current to be generated. The pixel circuit can control the time duration in which the driving current is applied to the light emitting element, so that the light emitting element can realize display of various grayscales by controlling the light emitting time of the light emitting element, on the premise that the light emitting element operates at a relatively high current density.
