1. A pixel circuit comprising:
a first wire;
a first light-emitting control unit, wherein a control terminal of the first light-emitting control unit is electrically connected to the first wire;
a driving unit, wherein one terminal of the driving unit is electrically connected to one terminal of the first light-emitting control unit;
a compensation unit, wherein one terminal of the compensation unit is electrically connected to the driving unit, another terminal of the compensation unit is electrically connected to a control terminal of the driving unit, and a control terminal of the compensation unit is electrically connected to the first wire;
a second wire;
a third wire;
a fourth wire;
a fifth wire;
a second light-emitting control unit, wherein one terminal of the second light-emitting control unit is directly connected to the second wire, another terminal of the second light-emitting control unit is directly connected to another terminal of the driving unit, and a control terminal of the second light-emitting control unit is directly connected to the third wire; and
an initialization unit, wherein a control terminal of the initialization unit is electrically connected to the fifth wire, one terminal of the initialization unit is electrically connected to the fourth wire, and another terminal of the initialization unit is directly connected to any one of one terminal of the first light-emitting control unit, another terminal of the first light-emitting control unit, or the control terminal of the driving unit;
wherein, in an initialization phase of the pixel circuit, at least one of the compensation unit, the first light-emitting control unit, and or the initialization unit is in an on state.
