Patent ID: 7791571

Claim:
A driving method of a light emitting device comprising: applying a video signal from a source signal line to a first transistor and a second transistor through a switching transistor; generating a first potential difference between a first electrode and a second electrode of a first light emitting element, wherein the first electrode of the first light emitting element is connected to a first current supply line, and the second electrode of the first light emitting element is connected to a second current supply line; generating a second potential difference between a first electrode and a second electrode of a second light emitting element, wherein the first electrode of the second light emitting element is connected to the second current supply line, and the second electrode of the second light emitting element is connected to a third current supply line; sequentially making the first light emitting element connected to the first transistor emit light based on the video signal and the first potential difference; and sequentially making the second light emitting element connected to the second transistor emit light based on the video signal and the second potential difference, wherein the first light emitting element and the second light emitting element emit light so that mixed light by the first and the second light emitting element becomes visually white.
