. The novel material combination consisting of the first compound and the second compound can enable the electroluminescent device to obtain a lower voltage, higher efficiency and an ultra-long lifetime and can provide better device performance. Further provided are a display assembly and a compound combination.
提供的是一种电致发光装置。该电致发光装置包括阳极、阴极和位于阳极和阴极之间的有机层,其中有机层包括至少一种具有H-L-E结构的第一化合物和具有M(La)m(Lb)n(Lc)q通式的第二化合物。该新型材料组合由第一化合物和第二化合物组成,可以使得电致发光装置获得更低的电压、更高的效率和超长的寿命,并提供更好的设备性能。另外还提供了一种显示组件和化合物组合。
