Micro-resonant cavity organic light-emitting diode with high refractive index contrast dielectric metasurfaces for naked-eye 3D display

Conventional naked-eye three-dimensional (3D) display technology based on organic light-emitting diode (OLED) combines reconstructing 3D scenes and advantages of OLED simultaneously, however, it requires multiple separate optical components, resulting in complex systems and bulky volumes. In this study, we propose a solution for the integration of resonant cavity and high refractive index contrast dielectric metasurfaces on OLED to endow the device with unidirectional light emission for naked-eye 3D display. We perform a systematical analysis on the effect of structure parameters of OLED that integrated distributed Bragg reflector and metasurfaces on its performance by employing the 3D finite-difference time-domain method. The simulation results show that top crystalline silicon (c-Si) metasurfaces are superior to the other metasurfaces structures, which can provide a larger deflection efficiency while remaining a small aspect ratio. We believe that this proposed single-chip resonant cavity OLED integrated a top c-Si metasurfaces structure could be a very promising candidate for naked-eye 3D OLED display.
