Provided are a pixel circuit, a driving method therefor, a display panel, and a display apparatus, so as to improve uniformity of brightness. The pixel circuit comprises a control sub-circuit (1), a compensation sub-circuit (2), a driving transistor (T1), and a light-emitting component (3). A gate of the driving transistor (T1) is connected to the compensation sub-circuit (2), a drain is connected to a variable voltage source, and a source is connected to the light-emitting component (3). The control sub-circuit (1) is used for controlling the compensation sub-circuit (2) to charge and discharge under the control of a scanning signal and a charging signal, and is also used for controlling the driving transistor (T1) to drive the light-emitting component (3) to emit light under the control of a light emitting control signal. The compensation sub-circuit (2) is used for implementing potential reset under the control of the control sub-circuit (1), and storing a threshold voltage of the driving transistor (T1) so as to compensate for the threshold voltage of the driving transistor (T1) when the driving transistor (T1) drives the light-emitting component (3) to emit light. |
