  • Patent number: 11250759
    Abstract: Systems and methods for adaptive color accuracy with multiple sensors to control a display's white point and to calibrate the display using pre-boot diagnostics are described. In some embodiments, an Information Handling System (IHS) may include a processor and a memory coupled to the processor, the memory having program instructions stored thereon that, upon execution, cause the IHS to: receive a first measurement from a first Ambient Light Sensor (ALS) disposed on a display portion of the IHS; receive a second measurement from a second ALS, wherein the second ALS is configured to face the display portion in response to IHS being in a closed posture; and control a brightness of a display based upon at least one of the first or second measurements.

  • Patent number: 11199744
    Abstract: An information handling system includes a display device, a camera, and a processor. The camera captures an image including first and second observers in a field of view in front of the display device. Based on the captured image, the processor determines a first location of the first observer and a second location of the second observer. Based on the first and second locations, the processor determines a first set of pixels located within a primary field of view for the first observer, and a second set of pixels located within a second field of view for the second observer. The processor calculates a viewing legibility adjustment for the second set of pixels. Based on the viewing legibility adjustment, the processor adjusts a contrast ratio for the second set of pixels to below a viewing threshold level.
