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.
Claims20
A system comprising:
- a display comprising a plurality of light sources;
- and
- a display controller including drive circuits for the plurality of light sources, the display controller configured to:
- determine a plurality of display zones of the display based on a field of view (FOV) of an eye of a user of the display;
- drive light sources in a first display zone of the plurality of display zones based on a first relationship between input display values and luminance levels for the light sources in the first display zone;
- and
- drive light sources in a second display zone of the plurality of display zones based on a second relationship between input display values and luminance levels for the light sources in the second display zone, wherein the second relationship is different from the first relationship.
A method comprising:
- determining a plurality of display zones of a display based on a field of view (FOV) of an eye of a user of the display;
- driving light sources in a first display zone of the plurality of display zones based on a first relationship between input display values and luminance levels for the light sources in the first display zone;
- and
- driving light sources in a second display zone of the plurality of display zones based on a second relationship between input display values and luminance levels for the light sources in the second display zone, wherein the second relationship is different from the first relationship.
A non-transitory machine-readable storage medium including instructions stored thereon, the instructions, when executed by a display controller, cause the display controller to perform operations including:
- determining a plurality of display zones of a display based on a field of view (FOV) of an eye of a user of the display;
- driving light sources in a first display zone of the plurality of display zones based on a first relationship between input display values and luminance levels for the light sources in the first display zone;
- and
- driving light sources in a second display zone of the plurality of display zones based on a second relationship between input display values and luminance levels for the light sources in the second display zone, wherein the second relationship is different from the first relationship.
