Organic light emitting display

An organic light emitting display (OLED), comprising:

• a display panel having a first region and a second region, said first region containing a first and second pads and said second region containing a plurality of pixels;
• a first power line electrically connecting the first and second pads and the plurality of pixels;
• a coupling member overlapping the first region of the displaying panel having a first and second coupling portions electrically connected to the first and second pads and a feedback line connected to the second coupling portion;
• a power supply external to and separate from the display panel and the coupling member, said power supply electrically connected to the coupling member supplying first power to the display panel, said feedback line transmitting the voltage of the second coupling portion to the power supply, and the power supply controlling an output voltage of the first power, corresponding to the voltage transmitted from the feedback line.
