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.
当有机发光器件的低灰度区域(例如 0 至 80 灰度)效率下降不稳定时,显示面板之间的偏差可能会导致低亮度区域的颜色变化和污点。本公开的各方面涉及一种克服这一问题的化合物以及包括该化合物的有机发光器件。该化合物可由式 1 表示:
研究发现,在缓冲层中含有这种化合物的有机发光器件在低灰度时的效率有所提高。
