Abstract:
1. A panel, comprising: a plurality of pixel circuits disposed in rows and columns and each including a light emitting element configured to emit light in response to driving current, a sampling transistor configured to sample an image signal, a driving transistor configured to supply the driving current to the light emitting element, and a storage capacitor configured to store a predetermined potential; a power supply scanner configured to supply a predetermined power supply voltage to the plurality of pixel circuits disposed in rows and columns; and a power supply line for connecting to all of the plurality of pixel circuits disposed in rows and columns and the power supply scanner to each other wherein the power supply scanner carries out power supply voltage control for all of the plurality of pixel circuits disposed in rows and columns in order to carry out a threshold value correction preparation operation and a threshold value correction operation simultaneously for all of the plurality of pixel circuits disposed in rows and columns within a vertical blanking period.
