Pixel circuit, driving method, electroluminescent display panel and display apparatus

A pixel circuit, comprising:

• a driving control module, a first light emitting control module, a light emitting device and a first capacitor;
• wherein,
• the first light emitting control module is coupled between the driving control module and a first electrode of the light emitting device, and the first light emitting control module is configured to load a driving current provided by the driving control module to the first electrode of the light emitting device under control of a valid light emitting control signal loaded to a light emitting control end;
• and
• a first end of the first capacitor is coupled with the light emitting control end, and a second end of the first capacitor is directly coupled with the first electrode of the light emitting device;
• and the first capacitor is configured to control the light emitting device to be in reverse cut-off when an invalid light emitting control signal loaded to the light emitting control end jumps to the valid light emitting control signal to make the light emitting device enter a luminescent period from a non-luminescent period and the driving current loaded to the first electrode of the light emitting device is smaller than a first preset gray-scale value;
• wherein the first preset gray-scale value is a maximum gray-scale value when the pixel circuit is in a black state;
• wherein in a case that the driving current loaded to the first electrode of the light emitting device is smaller than a second preset gray-scale value, the valid light emitting control signal is repeatedly loaded to the light emitting control end, and the light emitting control end jumps from the invalid light emitting control signal to the valid light emitting control signal multiple times;
• wherein each time the light emitting control end jumps from the invalid light emitting control signal to the valid light emitting control signal, a voltage of the first electrode of the light emitting device is decreased for one time through the first capacitor, and brightness of the light emitting device has one-time reduction;
• wherein the driving control module comprises a drive transistor and a second capacitor;
• wherein the second capacitor is coupled between a first power end and a gate of the drive transistor.
