A display having organic light emitting diode (OLED) material manages useful life based on usage environment by forecasting OLED driving-power events in generic and performance modes so that an end user can select how to view images over the display lifetime. Presentation of visual images to reduce OLED material degradation can include variations based on end user distance to the display and adjustments to visual image brightness with on-pixel ratio settings when HDR and SDR movies are presented. End user comfort when viewing the display is compared against a desired productivity to adjust viewing conditions at the display for improved user productivity.

A display having organic light emitting diode (OLED) material manages useful life based on usage environment by forecasting OLED driving-power events in generic and performance modes so that an end user can select how to view images over the display lifetime. Presentation of visual images to reduce OLED material degradation can include variations based on end user distance to the display and adjustments to visual image brightness with on-pixel ratio settings when HDR and SDR movies are presented. In one example embodiment, boundary visual image presentations are shifted to plural positions at the display based upon OLED material usage information.

System and method of operating a display of an information handling system

An information handling system organic light emitting diode (OLED) display adapts presentation of visual information to manage a display thermal state, such as to maintain a uniform thermal condition. In one example embodiment, a first display zone of plural pixels presents visual images with a first refresh rate, such as the nominal refresh rate established by the display settings, and a second display zone presents visual images with a partial pixel refresh rate that reduces power dissipation and, thus, thermal energy release so that a more uniform thermal state may be achieved at the display.

A liquid crystal display (LCD) device includes a LCD panel and a source driver. The LCD panel includes pixel data inputs and a failure sensing circuit. The pixel data inputs are coupled to columns of pixel elements. The failure sensing circuit provides a failure indication on an output of the LCD panel. In a test mode, the source driver drives a first voltage onto all of the first pixel data inputs. The failure indication includes the first voltage when the LCD panel has no failures on any of the first pixel elements, and the failure indication includes any other second voltage when the LCD panel has at least one failing pixel element.

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.
