摘要： A scanner repeats a threshold voltage correcting process over a plurality of horizontal periods prior to the sampling of a signal potential to hold a voltage corresponding to the threshold voltage of a driving transistor reliably in a retentive capacitor. Each signal line is associated with a pair of switches, one for supplying the signal potential to the signal line and the other for connecting, to the signal line, a common line for supplying a reference potential. A signal selector turns on and off the switches in each horizontal period in timed relation to a line sequential mode to switch between the signal potential and the reference potential and selectively supply the signal potential and the reference potential to the signal line of each column.

摘要： A display device includes a pixel array unit and a driver unit. A sampling transistor samples a signal potential to hold the signal potential in a holding capacitor. A driver transistor flows a drive current to a light emitting element in accordance with the signal potential held. A power supply scanner in the driver unit changes a power supply line from a first potential to a second potential before the sampling transistor samples the signal potential. A main scanner in the driver unit makes the sampling transistor conductive to apply a reference potential from the signal line to the gate of the driver transistor and to set the source of the driver transistor to a second potential. The power supply scanner changes the power supply line from the second potential to the first potential to hold a voltage corresponding to a threshold voltage off the driver transistor in the holding capacitor.
