Microdisplay Smear Reduction for HMDs
SA Photonics is developing novel methods to reduce motion based smear in microdisplays for use in head mounted displays (HMDs). Motion blur or smear can limit the performance of digital display systems. Smear comes from two primary display attributes – non-zero response time and finite hold time. The first effect causes an image from one frame to persist into a subsequent frame, and the second effect ensures that the image generated at the beginning of a frame is present until the end of that frame, regardless of the speed of response of the device. The human visual system interprets this persistence with moving imagery as smear.
