Abstract
One general aspect includes a system to tint at least a portion of a vehicle window, the system including: a memory configured to include one or more executable instructions and a processor configured to execute the executable instructions, where the executable instructions enable the processor to: monitor ambient light in a surrounding vehicle environment; and based on the ambient light, dim at least a portion of an OLED window located at a vehicle.
Claims17
A system to tint at least a portion of a vehicle window, the system comprising:
- a memory configured to comprise one or more executable instructions and a processor configured to execute the executable instructions, wherein the executable instructions enable the processor to:
- monitor an amount of ambient light in a surrounding vehicle environment;
- compare the monitored amount of ambient light to a threshold value;
- when the monitored amount of ambient light exceeds the threshold value, dim at least a portion of an OLED window located at a vehicle;
- and
- receive regulatory information from a remote database, wherein the regulatory information is related to minimum allowable VLT levels designated for a plurality of jurisdictional areas;
- receive a vehicle location;
- compare the vehicle location to the regulatory information to determine the minimum allowable VLT level for the vehicle location;
- establish the minimum VLT level for the OLED window;
- and
- wherein the OLED window cannot be dimmably adjusted to exceed the minimum VLT level.

A system to tint at least a portion of a vehicle window, the system comprising:
- a memory configured to comprise one or more executable instructions and a processor configured to execute the executable instructions, wherein the executable instructions enable the processor to:
- monitor an amount of ambient light in a surrounding vehicle environment via a light sensor located on a vehicle;
- compare the monitored amount of ambient light to a threshold value;
- when the monitored amount of ambient light exceeds the threshold value, monitor one or more facial features of a vehicle occupant via a camera located on a steering column of the vehicle;
- based on an orientation of the one or more facial features, identify a point of gaze (POG) position along a surface of an organic light-emitting diode (OLED) window that corresponds to the orientation of the one or more facial features;
- generate a dim spot relative to the POG position via the OLED window;
- and
- in response to feedback provided by the vehicle occupant, adjust a visible light transmission (VLT) level of the dim spot from a first VLT level to a second VLT level, wherein both the first VLT level and second VLT level correspond to actively inhibiting light distractors from being able to distract and/or temporarily blind a vehicle occupant, and wherein both the first VLT level and second VLT level block out a percentage of the light from the light distractor from passing through the dim spot.

A vehicle comprising:
- an organic light-emitting diode (OLED) window;
- a light sensor installed on a vehicle;
- a steering column comprising a camera;
- a cabin configured to hold at a vehicle occupant;
- a memory configured to comprise one or more executable instructions and a processor configured to execute the executable instructions, wherein the executable instructions enable the processor to:
- monitor an amount of ambient light in a surrounding vehicle environment via the light sensor;
- compare the monitored amount of ambient light to a threshold value;
- when the monitored amount of ambient light exceeds the threshold value, monitor one or more facial features of a vehicle occupant via the camera;
- based on an orientation of the one or more facial features, identify a point of gaze (POG) position along a surface of the OLED window that corresponds to the orientation of the one or more facial features;
- generate a dim spot relative to the POG position via the OLED window;
- and
- in response to feedback provided by the vehicle occupant, adjust a visible light transmission (VLT) level of the dim spot from a first VLT level to a second VLT level, wherein both the first VLT level and second VLT level correspond to actively inhibiting light distractors from being able to distract and/or temporarily blind a vehicle occupant, and wherein both the first VLT level and second VLT level block out a percentage of the light from the light distractor from passing through the dim spot.
