Organic light emitting display device

摘要

An organic light emitting display device includes a substrate including a display area on which a plurality of pixels are formed and a non-display area surrounding the display area; a first power line positioned on a lower non-display area; an auxiliary power line positioned on an upper non-display area; a first power supply supplying a first voltage to the first power line; and an auxiliary power supply supplying an auxiliary voltage to the auxiliary power line. Accordingly, it is possible to provide an organic light emitting display device capable of equalizing luminance by minimizing a variation in power supplied to each pixel.

主权项

1. An organic light emitting display device, comprising:
a substrate including a display area on which a plurality of pixels are formed and a non-display area surrounding the display area; a first power line disposed on the non-display area of the substrate; an auxiliary power line disposed on the non-display area of the substrate, the auxiliary power line being separated from the first power line; a first power supply supplying a first voltage to the first power line; an auxiliary power supply supplying an auxiliary voltage to the auxiliary power line; a plurality of pixel power lines directly connecting the auxiliary power line to the first power line, the pixel power lines coupled to the pixels and supplying a driving voltage to the pixels; and a power comparator comparing the auxiliary voltage to the first voltage, the power comparator supplying a control signal representing a compared result to the auxiliary power supply.
