Abstract
A display driving circuit includes a first transistor, a storage subcircuit, a compensation subcircuit, a data writing subcircuit, a light-emitting control subcircuit and a reverse bias subcircuit. The storage subcircuit is connected to a control terminal of the first transistor through a first node and to the first transistor through a second node. The compensation subcircuit is connected to a first light-emitting control line, the first transistor and a power supply high-voltage terminal. The data writing subcircuit is connected to a data line, a scan line and the first node. The light-emitting control subcircuit is connected to a second light-emitting control line, a second node and an anode of the display light-emitting subcircuit, a cathode of the display light-emitting subcircuit is connected to the scan line. The reverse bias subcircuit is connected to the scan line, a third node and the power supply high-voltage terminal.
