Researchers from Facebook Reality Labs and the University of Arizona published new work exploring the use of high-speed mechanical display shifting to reduce the so-called screen-door-effect (SDE) of immersive displays. SDE is caused by unlit spaces between pixels leading to the immersion-reducing appearance of a ‘screen door’ between the viewer and the virtual world. The researchers experiment with rapidly and minutely shifting the entire display to cause the display’s pixels to fill in the gaps.

SDE has been one the leading visual artifacts in modern VR headsets since the introduction of the Rift DK1 development kit in 2013. While SDE can be defeated with brute-force by employing extremely high density displays—in which the unlit spaces between…
