Organic light-emitting diodes (OLEDs) and quantum dots (QDs) are mainstream applications in large-sized displays. Owing to their narrow photoluminescence (PL), QDs offer a wide color gamut. Although OLEDs have a wider PL spectrum bandwidth than that of QDs, a high color purity can be obtained through an optical design of the top-emitting device. However, the luminance improvement from the strong cavity effect in a top-emitting geometry is not significant because of the wide PL spectrum. This insufficient luminance improvement can be compensated by applying organic light-emitting materials with horizontally oriented dipoles. Luminance compensation is color dependent. In a blue light-emitting structure, the luminance improvement by a narrow PL spectrum is more advantageous than by a horizontal dipole orientation. However, in green and red light-emitting structures, even if the full width at half maximum of the PL is about 20-nm-wide, luminance can be compensated using a horizontal dipole orientation while maintaining high color purity.

有机发光二极管（OLED）和量子点（QD）是大型显示器中的主流应用。由于其窄的光致发光（PL），QD提供了宽的色域。尽管OLED的PL光谱带宽比QD宽，但可以通过顶部发射器件的光学设计获得高色纯度。然而，由于宽的PL光谱，在顶部发射的几何形状中由强腔效应引起的亮度改善并不显着。通过施加具有水平取向的偶极子的有机发光材料，可以补偿这种不足的亮度提高。亮度补偿取决于颜色。在蓝色发光结构中，通过窄PL光谱的亮度提高比通过水平偶极子取向的亮度提高更有利。然而，
