Abstract
Microdisplay on silicon backplane is a promising architecture for XR systems. While digital circuitry is advantageous on silicon backplane, digital driving display introduces visual artifacts. First, we investigated the mechanism and solution of visual artifacts relevant for XR displays. Next, we proposed a intraframe time warp (ITW) to compensate for visual artifacts from head motion. ITW provide benefits to µOLED displays in XR systems by utilizing the higher frequency of digital driving. Lastly, we studied a 4K resolution digital µOLED displays expecting more than 40% of power saving in driving. The proposed digital driving solution with ITW is advantageous in power consumption and visual performance, however, the development of related technology is crucial to build the system.
