Pixel array and organic light emitting display device including the same

摘要

A pixel array and an organic light emitting display device including the same, can display an image with uniform luminance by compensating for a variation in threshold voltage/mobility of a driving transistor for each pixel and compensating for a change in efficiency due to degradation of an organic light emitting diode. A first pixel among the pixel array includes an organic light emitting diode; a pixel circuit positioned among an anode electrode of the organic light emitting diode, a first scan line and a first data line through which a data signal is supplied to the first pixel, and controlling current flowing in the organic light emitting diode; and a switching element controlling the coupling between a second data line through which a data signal is supplied to a second pixel of the plurality of pixels and the anode electrode of the organic light emitting diode.
