For the last 30 years, extensive OLEDs research and development has been conducted. Particularly, the innovation of new classes of organic light emitting materials such as room-temperature phosphorescence and thermally activated delayed fluorescence (TADF) realized nearly 100% electron into photon conversion. Further, we recently reported the indication of organic semiconductor laser diodes (OSLDs) under electrical pumping, that will open up a new era of organic optoelectronics. Simultaneously, organic/inorganic hybrid perovskites have been confirmed to possess a quite high potential for various application such as solar cells, FET, LED and laserapplications. In my talk, I will compare the characteristics of these devices and discuss the advantages and disadvantages of both materials and outlook their future prospect.
