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.

1. A pixel array, comprising:
a plurality of pixels, with a first pixel among the plurality of pixels comprising: 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 first data signal is supplied to the first pixel, the pixel circuit controlling current flowing in the organic light emitting diode; and a switching element controlling the coupling between a second data line through which a second data signal is supplied to a second pixel of the plurality of pixels and the anode electrode of the organic light emitting diode, in response to a control signal supplied through a control line, wherein the first pixel and the second pixel are different from each other.
