Abstract
A display device includes a light emitting element, a first driving transistor coupled to the light emitting element and supplied with a first driving voltage, and a second driving transistor coupled to the light emitting element and the first driving transistor and supplied with a second driving voltage having a magnitude different from the first driving voltage at least for a time. A method of driving the display device is also provided.
Claims33
A display device comprising:
- a light emitting element;
- a first driving transistor coupled to the light emitting element and supplied with a first driving voltage;
- and
- a second driving transistor coupled to the light emitting element and the first driving transistor and supplied with a second driving voltage having a magnitude different from the first driving voltage at least for a time.
1 more element
A display device comprising:
- a light emitting element;
- and
- at least one driving transistor supplying a current to the light emitting element,
- wherein a direction of a current flowing in the at least one driving transistor changes at least for a time.
1 more element
A display device comprising:
- a light emitting element;
- a first driving transistor supplying a current to the light emitting element;
- and
- a second driving transistor supplying a current to the light emitting element,
- wherein a current flowing in the first driving transistor points opposite a current flowing in the second driving transistor at least for a time.
2 more elements
