Abstract:
1. A display device comprising: a pixel array section; and a drive section configured to drive the pixel array section, the pixel array section including scan lines, signal lines, and pixels, the drive section including a main scanner configured to supply a control signal to each of the scan lines, and a signal selector configured to supply a signal potential serving as a video signal to the signal lines, wherein each of the pixels includes a light-emitting element, a sampling transistor, a drive transistor and a holding capacitor, the drive transistor and the light-emitting element being connected between a first voltage electrode and a second voltage electrode, the sampling transistor having a gate connected to a scan line, wherein during a period of time in which the signal line is supplied the signal potential, the main scanner supplies the control signal to the scan line to bring the sampling transistor into conduction so that the signal potential from the signal line is sampled and held in the holding capacitor, and the drive transistor passing a drive current through the light-emitting element according to the held signal potential, wherein the control signal has a rising edge and a falling edge, and a time constant of the rising edge is longer than a time constant of the falling edge, such that the rising edge of the control signal provides a first correction period when the signal potential is at a white level, a second correction period when the signal potential is at a gray level, and a third correction period when the signal potential is at a black level, wherein a difference between a duration of the third correction period and the second correction period is larger than a difference between a duration of the first correction period and the second correction period.
