VR device with high resolution, high luminance, and low power consumption using 1.50-in. organic light-emitting diode display

Abstract

We fabricated a microdisplay with a 1.50-in. organic light-emitting diode (OLED) and a pixel density as high as 3207 ppi. An ideal display with high luminance, low power consumption, an ultrahigh aperture ratio, and a wide color gamut can be fabricated using a metal maskless lithography technology for patterning OLED layers and an oxide semiconductor large-scale integration (OSLSI)/silicon LSI backplane. We designed a virtual reality device that exhibited less ghosting and a field of view of 90° or greater by combining the microdisplay and a novel pancake lens.
