In the present disclosure, it is provided a pixel circuit including a plurality of rows of pixel units and a row-shared unit, wherein each row of pixel units includes a plurality of sub-pixel units, and the row-shared unit includes a plurality of row-driving light-emitting control modules. All of the plurality of sub-pixel units included in each row of pixel units is connected to a corresponding signal line. Each row-driving light-emitting control module among the plurality of row-driving light-emitting control modules is connected to all of the sub-pixel units included in a corresponding one row of the pixel units among the plurality of rows of pixel units through the signal line, so as to provide a threshold compensation function.
