Head mounted display with directional panel illumination unit

Abstract

A head mounted display device includes a switchable light source that is switched to emit light for generating at least one viewing zone, and a panel illumination unit illuminated by the light source. The panel illumination unit converges the light onto an image panel that selectively transmits light at different pixels to generate image content. An eye monitor measures information pertaining to an eye configuration of a user, and the image content is visible to the user when the eye is aligned with respect to the viewing zone. The panel illumination unit converges the light such that light emitted by the image panel converges into the viewing zone positioned based on the eye configuration information measured by the eye monitor, with limited divergence such that when the display device is worn by the user, the image panel is located at a distance from the user's eye closer than a distance where the eye can focus the pixels.
