1. A non-transitory computer readable medium having instructions stored thereon that, upon execution by a controller, cause the controller to:
receive first data indicative of an ambient-light illuminance difference between a first illuminance of a first ambient light directed onto a first region of a display and a second illuminance of at least one second ambient light directed onto a second region of the display, wherein:
the first illuminance of the first ambient light is less than the second illuminance of the second ambient light;
the ambient-light illuminance difference is determined based on second data indicative of sensor outputs of a light sensor array associated with the display;
the light sensor array comprises:
a first group of sensors at or near one or more edges of the display, the first group of sensors configured to detect the first illuminance; and
a second group of sensors spaced away from the one or more edges of the display, the second group of sensors configured to detect the second illuminance; and
the second region overlaps with two or fewer edges of the display, and any edges of the two or fewer edges are different from the one or more edges of the display along which the first group of sensors is located, such that the second region is oriented over the second group of sensors and not the first group of sensors; and
send third data indicative of a control signal to control emitted light a light source array of the array, the control signal configured to cause the light source array to change a luminous emittance of the light source array within at least one of the first region or the second region of the display based on the ambient-light illuminance difference.
 
13. A method comprising:
receiving, by a controller of a computing device, first data indicative of an ambient-light illuminance difference between a first illuminance of a first ambient light directed onto a first region of a display and a second illuminance of at least one second ambient light directed onto a second region of the display, wherein:
the first illuminance of the first ambient light is less than the second illuminance of the second ambient light;
the ambient-light illuminance difference is determined based on second data indicative of sensor outputs of a light sensor array associated with the display;
the light sensor array comprises:
a first group of sensors at or near one or more edges of the display, the first group of sensors configured to detect the first illuminance; and
a second group of sensors spaced away from the one or more edges of the display, the second group of sensors configured to detect the second illuminance; and
the second region overlaps with two or fewer edges of the display, and any edges of the two or fewer edges are different from the one or more edges of the display along which the first group of sensors is located, such that the second region is oriented over the second group of sensors and not the first group of sensors; and
sending, by the controller, third data indicative of a control signal to control emitted light a light source array of the array, the control signal configured to cause the light source array to change a luminous emittance of the light source array within at least one of the first region or the second region of the display based on the ambient-light illuminance difference.
 
14. A non-transitory computer readable medium having instructions stored thereon that, upon execution by a controller, cause the controller to:
receive first data indicative of an ambient-light illuminance difference between a first illuminance of a first ambient light directed onto a first region of a display and a second illuminance of a least one second ambient light directed respectively onto a second region of the display, wherein:
the first illuminance is detected by a first portion of a light sensor array in the first region;
the second illuminance is detected by a second portion of the light sensor array in the second region;
the first region is different from the second region and the first portion of the light sensor array is different from the second portion of the light sensor array;
the ambient-light illuminance difference is determined based on the first illuminance and the second illuminance; and
the display comprises the light sensor array and a light source array configured to emit light to display an image on the display; and
send second data indicative of a control signal to control the light emitted from the light source array to change a luminous emittance of the light source array within at least one of the first region or the second region of the displayed image based on calibration data stored in a memory so as to reduce a spatial luminance difference between the first region and the second region of the displayed image on the display so as to present a uniformly displayed image to a user, wherein the calibration data relates the luminous emittance from the light source array to light source controls that control emitted light from the light source array.
