摘要

A self-luminous display device includes: pixel circuits; and a drive circuit, wherein each of the pixel circuits includes a light-emitting diode, a drive transistor connected to a drive current channel of the light-emitting diode, and a holding capacitor coupled to a control node of the drive transistor, the drive circuit applies a light emission enabling bias to the light-emitting diode after correcting the drive transistor and writing a data voltage to the control node, provides, during a light emission enabled period in which the light emission enabling bias is applied, a light emission interruption period adapted to change the light emission enabling bias to a non-light emission bias with the data voltage held by the holding capacitor, and performs a light emission disabling process, adapted to reverse-bias the light-emitting diode to stop the light emission, for a constant period after the light emission enabled period.
