Abstract
Head-mounted displays (HMDs) for virtual reality (VR) provide backlit illumination when the LCD rows corresponding to a non-dominant eye of the viewer are being updated. For example, when a human viewer operates a VR computer in the form of a smartphone with an LCD screen embedded in specialized goggles (e.g., Google Cardboard), the human viewer may specify that his/her right eye is dominant. In this case, the VR computer times the backlit illumination to be activated when the rows of LCD pixels in the field of view of the non-dominant, i.e., left, eye are being updated. When the rows of LCD pixels in the field of view of the dominant, i.e., right eye are being updated, the VR computer deactivates the backlit illumination.
