Abstract

An organic light emitting display device capable of minimizing an IR drop of pixel power sources supplied to an organic light emitting display panel is taught. The organic light emitting display device includes an organic light emitting display panel comprising a first side on which an image is displayed and a second side that faces the first side and a plurality of first and second power source pads provided at two or more edges of the second side to receive first and second pixel power sources in at least two different directions; and a pixel power source supplying flexible printed circuit board (FPCB) provided on the second side of the organic light emitting display panel to comprise a plurality of pads electrically coupled to the first and second power source pads and to supply the first and second pixel power sources to the organic light emitting display panel.

Claims (29)

3. The organic light emitting display device of claim 1 , in which the plurality of first power source pads are formed at a first edge region of the second surface of the organic light emitting display panel and a second edge region that faces the first edge region.

4. The organic light emitting display device of claim 1 , in which the plurality of second power source pads are formed at a third edge region of the second surface and a fourth edge region that faces the third edge region.

5. The organic light emitting display device of claim 1 , in which the plurality of first power source pads and the plurality of second power source pads are formed at different edges of the second surface of the organic light emitting display panel.

6. The organic light emitting display device of claim 1 , in which the plurality of first and second power source pads respectively receive the first and second pixel power sources of the pixel power source supplying flexible printed circuit board (FPCB) in two different directions that are opposite to each other and that face each other.

7. The organic light emitting display device of claim 1 ,

in which a pixel unit that receives the first and second pixel power sources from the plurality of first and second power source pads is positioned in the center of the organic light emitting display panel, and a plurality of signal pads for supplying driving signals to the pixel unit are formed between the plurality of first and second power source pads.

8. The organic light emitting display device of claim 7 , in which the plurality of signal pads are electrically coupled to driving flexible printed circuit boards (FPCBs) provided in addition to the pixel power source supplying flexible printed circuit board (FPCB) to transmit the driving signals supplied from the driving flexible printed circuit boards (FPCBs) to the pixel unit.

9. The organic light emitting display device of claim 8 , in which the driving flexible printed circuit boards (FPCBs) are plural.

10. The organic light emitting display device of claim 8 , in which at least one of a scan driver and a data driver is mounted on the driving flexible printed circuit boards (FPCBs) to supply at least one of the scan signals and the data signals to the pixel unit.
