    • A pixel and an organic light emitting display device using the same, which can improve display quality, are provided. An organic light emitting display device includes pixels, an emission control line, an initial power supply unit, a scan driver and a data driver. The pixels are at intersection portions of scan lines and data lines. The emission control line is commonly coupled to the pixels. The initial power supply unit is commonly coupled to gate electrodes of one or more transistors included in each of the pixels, and supplies a first voltage during a first period, a second voltage lower than the first voltage during a second period, and a third voltage higher than the first voltage during a third period in one frame period. The scan driver drives the scan lines and the emission control line. The data driver drives the data lines.
    • 提供了可以提高显示质量的像素和使用该像素的有机发光显示装置。 有机发光显示装置包括像素,发光控制线,初始电源单元,扫描驱动器和数据驱动器。 像素是扫描线和数据线的相交部分。 发射控制线通常耦合到像素。 初始电源单元通常耦合到每个像素中包括的一个或多个晶体管的栅电极,并且在第一周期期间提供第一电压,在第二周期期间提供低于第一电压的第二电压,以及第三电压 高于在一个帧周期的第三个周期期间的第一个电压。 扫描驱动器驱动扫描线和排放控制线。 数据驱动器驱动数据线。
