Abstract:
A self-luminous display device includes: pixel circuits; and a drive signal generating circuit, wherein each of the pixel circuits includes a light-emitting diode, a drive transistor connected to a drive current path of the light-emitting diode, and a holding capacitor coupled to a control node of the drive transistor, and the drive signal generating circuit generates the drive signal containing a second level signal adapted to stop the light emission without reverse-biasing the light-emitting diode, a first level signal, lower than the second level signal, adapted to reverse-bias the light-emitting diode, and a third level signal, higher than the second level signal, adapted to enable the light-emitting diode to emit light, the drive signal generating circuit supplying the drive signal to the pixel circuits.
