A pixel circuit, an organic electroluminescent display panel and a display apparatus are provided. The pixel circuit comprises: a light-emitting device (D1), a drive control module (1), a reset control module (2), a charge control module (3) and a light-emitting control module (4). The reset control module (2) is used for resetting the light-emitting device (D1) in an internal compensation mode, and exporting a current signal of the drive control module (1) for driving the light-emitting device (D1) and comparing the same with a preset standard current value to determine a compensation factor in an external compensation mode. The charge control module (3) is used for charging and writing a data signal (Data) into the drive control module (1) in the internal compensation mode and writing the data signal (Data) into the drive control module (1) in the external compensation mode. The light-emitting control module (4) is used for charging the drive control module (1) and controlling the drive control module (1) to drive the light-emitting device (D1) to emit light in the internal compensation mode, and controlling the drive control module (1) to drive the light-emitting device (D1) to emit light in the external compensation mode. Therefore, a same pixel circuit can be shared for both internal compensation and external compensation. |
