New ultra‐low power OLED microdisplays for slim near‐to‐eye visualization

OLED microdisplays have entered several professional and consumer near-to-eye visualization devices, such as VR/AR, assisted-reality or electronic viewfinder. Head-, helmet- or eyeglass frame-mounted displays, smart glasses or visors provide user information for human-machine interaction, situational awareness, personal safety, remote support or training. Display architecture and parameters, such as screen size, pixel density, resolution, color range and auxiliary functions can be varied to achieve high-resolution extended full-HD for VR/AR or ultra low-power options for long battery life in true wearables. This report is focusing on the design and characteristics of newly developed ultra-low power and slim form factor OLED microdisplay devices, featuring <0.2” screen diagonal, QVGA resolution at pixel density <2150ppi and monochrome as well as color versions.
