Abstract
Abstract This work introduces LG Display's (LGD's) 1.3″ 4K full‐color organic light‐emitting diode (OLED) microdisplay panels with a peak brightness of more than 10,000 nits, which have been newly developed for high‐quality virtual reality/mixed reality (VR/MR) head‐mounted displays. To achieve these advanced high‐luminance OLED microdisplay panels, we have developed a well‐controlled optical microcavity and outcoupling method, along with optimized multi‐stack white OLED devices and CF‐on‐encapsulation technologies tailored to the high pixel density of the panels.
