When a decrease in low-grey level region (e.g., 0 to 80 grey) efficiencies of organic light emitting devices is not constant, deviation among display panels may cause color change and stain in the low luminance region. Aspects of the present disclosure are directed toward a compound to overcome this problem and an organic light-emitting device including the same. The compound may be represented by Formula 1:
Organic light-emitting devices including this compound in the buffer layer were found to have improved efficiencies at low grey levels.
当有机发光器件低灰度区域(例如0到80灰度)效率下降不稳定时,显示面板之间的偏差可能导致低亮度区域的颜色变化和污渍。本公开的方面涉及一种化合物,用于克服这一问题,以及包括该化合物的有机发光器件。该化合物可用Formula 1表示:在缓冲层中包含这种化合物的有机发光器件发现在低灰度水平上具有改善的效率。
