Abstract:
1. A display device comprising: a pixel array unit and a driving unit which drives the pixel array unit, wherein the pixel array unit includes wherein the driving unit includes wherein the pixel includes wherein the sampling transistor is connected to the scanning line at a gate thereof, connected to the signal line at one of a source and a drain thereof, connected to a gate of the driving transistor at the other of the source and the drain, wherein the driving transistor is connected to the light emitting element at one of a source and a drain thereof, and connected to the power supply line at the other of the source and the drain thereof and in which the storage capacitor is connected between the source and the gate of the driving transistor, wherein the sampling transistor is turned on according to the control signal supplied from the scanning line and samples the signal potential supplied from the signal line to be stored in the storage capacitor, wherein the driving transistor receives supply of current from the power supply line at the first potential and allows drive current to flow in the light emitting element according to the stored signal potential, wherein the main scanner outputs the control signal to the scanning line at a timing of turning on the sampling transistor at a time slot when the signal line is at the signal potential, thereby writing the signal potential in the storage capacitor, as well as adds a correction to the signal potential, which is for mobility of the driving transistor, and wherein the pixel includes an auxiliary capacitor in order to increase write gain when storing the signal potential in the storage capacitor and in order to adjust time necessary for the correction of mobility.
