    • 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.
    • 像素阵列和包括该像素阵列的有机发光显示装置可以通过补偿每个像素的驱动晶体管的阈值电压/迁移率的变化来补偿具有均匀亮度的图像,并补偿由于劣化导致的效率的变化 有机发光二极管。 像素阵列中的第一像素包括有机发光二极管; 位于有机发光二极管的阳极之间的像素电路,第一扫描线和第一数据线,数据信号通过该第一数据线提供给第一像素,并控制在有机发光二极管中流动的电流; 以及开关元件,其控制将数据信号提供给所述多个像素中的第二像素的第二数据线与所述有机发光二极管的所述阳极之间的耦合。
