Pixel circuit and drive method therefor, and display apparatus

A pixel circuit, comprising a drive sub-circuit, a writing sub-circuit, a first reset sub-circuit, and a light emitting element, wherein:

• the drive sub-circuit is configured to provide a drive current between a first electrode and a second electrode of the drive sub-circuit in response to a control signal of a first node;
• the writing sub-circuit is configured to write a data voltage signal to the first electrode of the drive sub-circuit in response to a control signal of a first scan signal line;
• the first reset sub-circuit is configured to reset an anode terminal of the light emitting element in response to a control signal of a second scan signal line;
• and
• in a low frequency display mode, an input frequency of the control signal of the first scan signal line is the same as a data refresh frequency, and an input frequency of the control signal of the second scan signal line is greater than the data refresh frequency,
• wherein the pixel circuit further comprises a compensation sub-circuit, a storage sub-circuit, a leakage-proof sub-circuit, wherein:
• the compensation sub-circuit is configured to compensate a fifth node in response to the control signal of the first scan signal line;
• the storage sub-circuit is connected with a first power line and the first node respectively;
• and
• the leakage-proof sub-circuit is configured to write a signal of the fifth node to the first node in response to a control signal of a third scan signal line.
