Claim 19:
20. A display apparatus, comprising: light emitting elements arranged in a matrix; pixel circuits arranged in a matrix; a scan signal line; a data signal line; an initial signal line; a light emitting control line; a first power supply line; a first reset line; and a second reset line; wherein:
each of the pixel circuits is configured to drive a corresponding light emitting element to emit light, and the pixel circuit comprises a first reset sub-circuit, a node control sub-circuit, and a light emitting control sub-circuit;
the first reset sub-circuit is connected with the first reset line, the scan signal line, the initial signal line and a first node, and configured to provide a signal of the initial signal line for the first node under control of the first reset line and the scan signal line;
the node control sub-circuit is connected with the scan signal line, the second reset line, the data signal line, the first node, a second node, a third node and a first power supply line, and configured to provide a signal of the data signal line for the second node under control of the scan signal line and the second reset line, compensate for the first node through the second node and the third node until a voltage of the first node satisfies a threshold condition; and
the light emitting control sub-circuit is connected with the light emitting control line, the first power supply line, the node control sub-circuit and the light emitting element, and used for providing a signal transmitted through the node control sub-circuit for the light emitting element, and wherein:
each pixel circuit comprises: a storage capacitor, the storage capacitor comprises a first plate and a second plate, the first plate is connected with the first power supply line, and the second plate is connected with the first node;
an orthographic projection of the first plate on a base partially overlaps an orthographic projection of the second plate on the base, the first plate is provided with a via, and the via of the first plate exposes the second plate;
the scan signal line, the first reset line and the second reset line are located on a side of the second plate, and the light emitting control line is located on a side of the second plate away from the first reset line; and
the first reset line is located on a side of the scan signal line away from the second plate, and the second reset line is located on a side of the scan signal line close to the second plate.
