Patent ID: 8836690

Claim:
A display apparatus comprising: a pixel array section and a drive section, said pixel array section having power supply lines, scan lines arranged in rows, signal lines arranged in columns, and pixels arranged in a matrix at intersections of said scan lines and said signal lines, at least one of said pixels comprising a sampling transistor, a drive transistor, a light emitting device, and a capacitor, said sampling transistor being connected at a control terminal to one of said scan lines, at a first current terminal to one of said signal lines, and at a second current terminal to a control terminal of said drive transistor, said drive transistor being connected at a first current terminal to said light emitting device and at a second current terminal to one of said power supply line, said drive section supplying a control signal to one of said scan lines and a video signal to one of said signal lines, and executing a threshold voltage correcting operation for correcting a fluctuation of a threshold voltage of said drive transistor, a write operation for writing said video signal to said capacitor, and a light emitting operation for driving said light emitting device to emit light in accordance with the written video signal, said threshold voltage correcting operation including a preparation portion in which, while the control terminal of said drive transistor is maintained at a reference potential, a gate-to-source voltage with the first current terminal of said drive transistor is set higher than said threshold voltage to turn on said drive transistor and an energizing portion in which said drive transistor is energized with said control terminal maintained at the reference potential to hold, in said capacitor, a voltage equivalent to said threshold voltage appearing between said control terminal and said first terminal of said drive transistor when said drive transistor is cut off, said energizing portion being executed in a time division manner a plurality of times until said drive transistor cuts off, there being a difference between a reference potential to be applied to the control terminal of said drive transistor in a preceding energizing portion and the reference potential to be applied to the control terminal of said drive transistor in a following energizing portion; wherein a voltage at said source of said drive transistor is brought to an initial voltage and then said voltage rises iteratively during a threshold voltage correction period, a signal potential writing period, a light emitting period and rises continuously throughout the signal potential writing period, and the voltage at said source of said drive transistor at an ending time of the signal potential writing period is lower than 0V.
