1. A pixel circuit, applicable to a display apparatus and comprising:
a first storage sub-circuit, connected between a first node and a second node;
a driving sub-circuit, connected to the first node, a third node, and a fourth node, to control connection or disconnection between the third node and the fourth node under control of the first node; wherein the third node is connected to a first power supply terminal;
a light-emitting control sub-circuit, connected to the fourth node and a first electrode of a sub-pixel, to control connection or disconnection between the fourth node and the first electrode of the sub-pixel;
a second storage sub-circuit, connected to the first node, to store a potential of the first node;
a data writing sub-circuit, connected to the second node, to input a voltage to the second node, wherein the second node is disposed between the data writing sub-circuit and the first storage sub-circuit; and
a compensation sub-circuit, connected to a first scanning signal terminal and the first node, wherein the compensation sub-circuit is directly connected to the first node;
wherein the compensation sub-circuit is further connected to the third node, to control connection or disconnection between the first node and the third node under control of the first scanning signal terminal; or,
the compensation sub-circuit is further connected to the fourth node, to control connection or disconnection between the first node and the fourth node under the control of the first scanning signal terminal.
