Abstract:
A method including determining a maximum luminance location of a display based on a field of view of an eye of a user of the display, and driving a plurality of light sources in the display based on locations of the plurality of light sources with respect to the maximum luminance location of the display. The plurality of light sources is controlled to have different luminance levels in different display zones corresponding to different zones on the retina of the eye of the user. In some examples, the display zones of the display system that have higher luminance levels can be dynamically changed based on the field of view or the gaze direction of the eye of the user.
