Abstract
An electronic device such as a head mounted device may have a display that displays an image for a user. Head-mounted support structures may be used to support the display and to support lenses. The image on the display is visible through the lenses from eye boxes. The presence of the user's nose and the presence of opaque lens holder structures presents a risk that some of the image will be obscured by undesired black regions. To reduce or eliminate these black regions, facial illumination may be generated using a light source in the electronic device. The facial illumination may be provided by a light source such as a light-emitting diode die or laser or may be provided by a corner region of the display that contains pixels that do not supply any part of the image.
