Abstract
Disclosed are a display device and a driving method thereof. A pixel circuit of the display device may be driven in a data sampling phase and a light emitting phase. A electric current flows in a first effective channel of a driving element in the data sampling phase and a electric current flows in a second effective channel of the driving element in the light-emitting phase.
Claims11
A display device comprising a pixel circuit including a driving element for driving a light emitting element, wherein the driving element comprises:
- an active pattern having first and second effective channels and having different lengths of a current path,
- wherein a data voltage is applied to a gate of the driving element and a current flows in the first effective channel during a data sampling phase,
- wherein an electric current flows in the second effective channel during a light emitting phase, and
- the length of the second effective channel is shorter than the length of the first effective channel.
A method for driving a display device including a pixel circuit including a driving element for driving a light emitting element,
- the method comprising:
- applying a data voltage to a gate of the driving element in a data sampling phase;
- and
- supplying a electric current to the light emitting element during a light emitting phase,
- wherein the electric current flows in a first effective channel of the driving element in the data sampling phase,
- the electric current flows in a second effective channel of the driving element in the light emitting phase, and
- a length of the second effective channel is shorter than a length of the first effective channel.
