Patent ID: 7663577

Claim:
An organic light emitting display device including a plurality of electroluminescent (EL) panels coupled together to display an image, the device comprising: a pixel portion comprising a plurality of pixels to display an image; a plurality of data driving circuits spaced apart from one another to transmit a data signal to the pixel portion; a scan driver arranged between the data driving circuits and the pixel portion, and disposed on a substrate on which the pixel portion is disposed; an emission control driver arranged between the data driving circuits and the pixel portion, and disposed on the substrate on which the pixel portion is disposed; a plurality of data lines to transmit the data signal from the data driving circuits to the pixel portion; a plurality of scan lines extending from the scan driver to the pixel portion to transmit a scan signal to the pixel portion, the scan lines being disposed substantially parallel to the data lines; a plurality of emission control lines extending from the emission control driver to the pixel portion to transmit an emission control signal to the pixel portion, the emission control lines being disposed substantially parallel to the scan lines; and power supply voltage lines extending from a power supply pad portion to the pixel portion to transmit a power supply voltage to the pixel portion, the power supply voltage lines being disposed substantially parallel to the emission control lines, wherein the power supply pad portion is arranged between adjacent data driving circuits.
