Abstract
Disclosed is an organic light-emitting display device defined into a non-display area and a display area which is provided with pixels. Each of the pixels includes: first through fourth nodes; an organic light emission element connected to the fourth node; a drive transistor disposed between the second, third, and fourth nodes and configured to generate a drive current which drives the organic light emission element to emit light; a storage capacitor disposed between the first and third nodes; first through fifth transistors; wherein the fifth transistor is disposed between the second node with the non-display area and a reference voltage line and configured to control an initialization of the second node.
Claims14
An organic light emitting display device comprising:
- a pixel disposed in a display area of the organic light emitting display device, the pixel comprising:
- first through fourth nodes;
- an organic light emission element connected to the fourth node;
- a drive transistor disposed between the second, third, and fourth nodes to generate a drive current which drives the organic light emission element to emit light;
- a storage capacitor disposed between the first and third nodes;
- a first transistor disposed between the first and second nodes;
- a second transistor disposed between the third and fourth nodes;
- a third transistor disposed between the first node and a data line to selectively transfer a data voltage from the data line to the first node;
- and
- a fourth transistor directly connected to the second node and a power line to selectively transfer a power voltage from the power line to the second node;
- and
- a fifth transistor disposed in a non-display area of the organic light emitting display device, a drain electrode of the fifth transistor connected to the second node and a source electrode of the fifth transistor connected to a reference voltage line to control an initialization of the second node.
