61.1 - Invited Paper: Polaritonic OLEDs with Assistant Strong-Coupling Layers: A New Approach to Sub-20nm Emission Linewidth in OLED Displays (10:40 AM - 11:00 AM)

To reach narrowband emission without spectrum change with observation angle, the authors hybridize microcavity photons and excitons in an efficient OLED, called polaritonic OLED. They use assistant strong-coupling layers located away from the recombination zone results in an efficient OLED with FWHM < 20nm and shift of < 10nm at 60° observation angle.
61.2 - Invited Paper: Light-Emitting Diodes Based on Metal-Halide Perovskites and Beyond (11:00 AM - 11:20 AM)

Despite recent rapid development, LEDs have not achieved their full potential in terms of performance and cost efficiency. Recently, metal-halide perovskites and perovskite-related hybrids have emerged as new-generation luminescent materials with unique optoelectronic properties. Here, the recent development of LEDs based on metal-halide perovskites and beyond will be discussed.
61.3 - Distinguished Paper: Realization of an Organic Semiconductor Electroluminescent Device with High Directionality and Color Purity (11:20 AM - 11:40 AM)

An organic electroluminescence device with high directionality (divergent angle 1.1°) and high color purity (FWHM of 2.5 nm) is introduced. This achievement is realized through recombination zone control and optical modes management. This work marks the world's first demonstration of an organic device with narrow FWHM and excellent directionality.
