Abstract:
1. A display apparatus, comprising: a pixel array section having a plurality of pixels disposed in a matrix and each including a power supply scanning circuit configured to selectively supply a first power supply potential and a second power supply potential which is lower than the first power supply potential to said power supply line; and a signal outputting circuit configured to selectively output an image signal, a first reference potential, a second reference potential lower than the first reference potential and a third reference potential higher than the second reference potential to said signal line; said power supply scanning circuit being operable to supply the second power supply potential to the second electrode of said driving transistor through said power supply line to initialize the potential of the second electrode of said driving transistor and then change over the potential of said power supply line from the second power supply potential to the first power supply potential; said signal outputting circuit being operable to output, when said writing transistor is in a conducting state in response to a scanning signal supplied thereto through said scanning line, the first reference potential to said signal line so as to be supplied to the gate electrode of said driving transistor through said writing transistor to initialize the potential of the gate electrode of said driving transistor, supply, midway while a threshold value correction process of varying the potential of the second electrode of said driving transistor toward a potential which is the difference of a threshold voltage of said driving transistor from an initialization potential for the gate electrode of said driving transistor with reference to the initialization potential is carried out, the second reference potential to said signal line in place of the first reference potential so as to be supplied to the gate electrode of said driving transistor through said writing transistor, output the third reference potential in place of the second reference potential to said signal line within a period within which said writing transistor remains in the conducting state, and output the image signal in place of the third reference potential to said signal line after the threshold correction process ends.
