    Abstract: The present disclosure provides a pixel circuit, an organic electroluminescence display panel and a display apparatus. The pixel circuit initializes a first node during an initialization period of a touch control phase and a display phase; adjusts a voltage at the first node during a touch sensing period of the touch control phase; causes a driver module to output a touch control signal under the control of the voltage at the first node during a touch reading period of the touch control phase, so as to achieve a touch control function; writes data into the first node during a compensating period and a data writing period of the display phase; and causes the driver module to drive a light emitting device in a light emitting module to emit light during a light emitting period of the display phase, so as to allow the light emitting device to achieve its light emitting function normally. Compared with the conventional pixel circuit, the pixel circuit according to the embodiment of the present disclosure has integrated touch control and display functions. In this way, the manufacture cost can be saved when compared with the separated provided display driver circuit and touch control circuit, so as to simplify the circuit structure and to reduce the thickness of the display panel.
