Pixel circuit and driving method thereof, array substrate and display device

A pixel circuit, comprising:

• an inorganic electroluminescent device, a scan terminal, a data write terminal, a first level input terminal, a second level input terminal, a gating circuit, a drive circuit, and an energy storage circuit, wherein
• a control terminal of the gating circuit is connected with the scan terminal, an input terminal thereof is connected with the data write terminal, and an output terminal thereof is connected with a control terminal of the drive circuit, wherein the gating circuit is configured to be switched on when an ON signal is inputted into the scan terminal and switched off when an OFF signal is inputted into the scan terminal;
• an input terminal of the drive circuit is connected with the first level input terminal, and an output terminal thereof is connected with a first pole of the inorganic electroluminescent device, wherein the drive circuit is configured to provide a corresponding drive current to the inorganic electroluminescent device according to a data signal received at the control terminal thereof;
• a second pole of the inorganic electroluminescent device is connected with the second level input terminal;
• and
• a first terminal of the energy storage circuit is connected with the first level input terminal, and a second terminal thereof is connected with the control terminal of the drive circuit, wherein the energy storage circuit is configured to store energy when the ON signal is inputted into the scan terminal and release the stored energy when the OFF signal is inputted into the scan terminal.
