Classification: CPC G | IPC G

Claim 7:
8. A method of driving a light emitting element comprising:
providing a high voltage to a first terminal of a drive transistor at the same time that an initialization voltage is provided to a gate of the drive transistor during a first time period;
electrically isolating a first terminal of the light emitting element from a second terminal of the drive transistor during the first time period;
providing a data signal that contains light emission data to a gate of the drive transistor during a second time period;
maintaining the first terminal of the light emitting element being electrically isolated from the second terminal of the drive transistor during the second time period;
providing a sense signal to a gate of a sense switching transistor during both the first and the second time periods, the sense switching transistor having a first terminal electrically connected to the first terminal of the light emitting element;
boosting the voltage on the gate of the drive transistor during a third time period;
electrically connecting the first terminal of the light emitting element to the second terminal of the drive transistor during the third time period; and
emitting light from the light emitting element during a fourth time period.
