The organic light‐emitting diode (OLED) has gained widespread commercial use, yet there is a continuous need to identify innovative emitters that offer higher efficiency and a broader color gamut. To effectively screen out promising OLED molecules that are yet to be synthesized, representation learning aided high throughput virtual screening (HTVS) over millions of Ir(III) complexes, which are prototypical types of phosphorescent OLED material constructed via a random combination of 278 reported ligands. This study successfully screens out a decent amount of promising candidates for both display and lighting purposes, which are worth further experimental investigation. The high efficiency and accuracy of this model are largely attributed to the pioneering attempt of using representation learning to organic luminescent molecules, which is initiated by a pre‐training procedure with over 1.6 million 3D molecular structures and frontier orbital energies predicted via semi‐empirical methods, followed by a fine‐tuning scheme via the quantum mechanical computed properties over around 1500 candidates. Such workflow enables an effective model construction process that is otherwise hindered by the scarcity of labeled data and can be straightforwardly extended to the discovery of other novel materials.

Organic light-emitting diodes (OLEDs) have gained widespread commercial use, yet there is a continuous need to identify innovative emitters that offer higher efficiency and broader color gamut. To effectively screen out promising OLED molecules that are yet to be synthesized, we perform a representation learning aided high throughput virtual screening (HTVS) over millions of Ir(III) complexes, a prototypical type of phosphorescent OLED material, constructed via a random combination of 278 reported ligands. We successfully screen out a decent amount of promising candidates for both display and lighting purposes, which are worth further experimental investigation. The high efficiency and accuracy of our model are largely attributed to the pioneering attempt of using representation learning to organic luminescent molecules, which is initiated by a pre-training procedure with over 1.6 million 3D molecular structures and frontier orbital energies predicted via semi-empirical methods, followed by a fine-tune scheme via the quantum mechanical computed properties over around 1500 candidates.

“…Distinguished from LED or xenon lamp, the color of laser is pure and its chromaticity coordinates lie on the spectrum locus of gamut charts. It can be more than 70% of the total range of colors perceivable by humans due to the monochromaticity of laser source [7]. Except for two-dimensional display, laser is also the ideal light source for holographic three-dimensional display [8].…”

Laser-based displays can offer a wide color gamut to the viewers due to the narrow bandwidth of laser source, which is quite different from traditional display systems. Therefore, the color rendition standards for traditional displays are no longer suitable for laser-based displays. An optimized and practical color reproduction system is proposed and demonstrated for laser-based displays in this paper. Not only the three primary wavelengths are well chosen by considering the luminance efficiency, color gamut, and color matching function, but also the response function of a camera system is optimized for a simplified color reproduction procedure. A remarkably high color rendition quality is presented in our experiment compared with traditional displays.
