Herein, we report white organic light emitting diodes on silicon (OLEDoS) devices with ultra-thin charge generation units (CGUs) of 10 nm thickness for augmented reality (AR) and virtual reality (VR) applications. In device performance, it showed low driving voltage of 6.2 V at 2,000 cd/m2 and maximum luminance of 50,015 cd/m2 at 10.0 V. Maximum current efficiency of 20.0 cd/A was achieved. It also showed high color stability of (0.155±0.001, 0.492±0.007) from 500 cd/m2 to 2,000 cd/m2 in Commission Internationale de l’Eclairage (CIE) 1976 color space.
