Abstract: A display driving circuit for a display device includes a pixel receiving a first power supply voltage and a second power supply voltage. The pixel comprises a driving transistor configured to generate a driving current, a data writing transistor configured to provide a data voltage to the driving transistor, and a light-emitting element configured to emit light based on the driving current. A display controller controls the first and second power supply voltages during an emission period of a frame period. The emission period includes sub-emission periods in which the pixel emits light and black insertion periods in which the pixel does not emit light, alternating with one another. The display driving circuit adjusts the power supply voltages to regulate the transitions between these periods, coordinating the operation of the pixel within the frame period.
