摘要： Described herein are methods and a system to correct environmental light reflecting onto a surface of a display. An image is captured by camera which is processed as an image digital map. Light sources on the image digital map are determined based on correlated camera pixel map and display map. Light sources are on the image digital map are augmented by one or more ambient light sensors (ALS) placed on the periphery of the display. Image correction is performed based on the light sources of the image digital map.

摘要： End user interactions at a display are monitored for predetermined conditions to provide augmentation of display presentation by a red light that illuminates in the 650 to 800 nm range, such as at substantially 670 nm. Instructions stored in non-transient memory and executed on a processor present visual images of varied color contrast and evaluate end user inputs to determine an end user visual acuity. Over time and use of the display and red light, end user visual acuity is periodically tested to evaluate the effectiveness of red light illumination to restore visual acuity.

摘要： Method and system for providing, for display on a display device of an information handling system (IHS), one or more images; generating, by a blue-light mitigation computing module, a model of blue-light energy exposure based on the i) the blue-light energy output level of each image, ii) the environmental illumination brightness level, iii) the environmental illumination white color point, iv) the distance of the user, and v) the user exposure time; determining, by the blue-light mitigation computing module and based on the model, that a current blue-light energy exposure of the user with respect to the display device is above a threshold; and in response to determining that the current blue-light energy exposure of the user with respect to the display device is above the threshold, performing, by the blue-light mitigation computing module, an action to mitigate the blue-light energy exposure of the user.

摘要： A first light emitting diode has a first driving input, and emits a red color light. A second light emitting diode has a second driving input, and emits a green color light. A third light emitting diode has a third driving input, and emits a blue color light. When a first current is applied to the third driving input, the third light emitting diode produces a first amount of blue light energy. When a second current is applied to the third driving input, the third light emitting diode produces a second amount of the blue light energy. The second amount of blue light energy corresponds to a percentage of blue energy reduction as compared to the amount of first blue light energy.

摘要： A portable information handling system display provides a narrow bezel footprint with a diagonally disposed touch grid that passes touch detection conductive traces from opposing parallel sides of a rectangular protective cover. In one embodiment, the protective cover at the opposing parallel sides folds to the rear of the display to interface the touch grid to one or more cables and a touch controller.

摘要： Apparatus and methods may be implemented to provide multi-layer display assembly apparatus for information handling systems, including portable information handling systems (e.g., such as smart phones, tablet computers, notebook computers, etc.) as well as display assembly apparatus for other types of information handling systems such as desktop computers, servers, etc. The disclosed multi-layer display assembly apparatus may be implemented to include multiple adhesive layers (e.g., two or more adhesive layers) that have different indices of refraction and/or different debonding characteristics, and that are disposed between a display substrate and an transparent protective hardcover such as glass-based or plastic-based cover.

摘要： A display presents information with pixels driven at overdrive voltages set based upon a user configuration and sensed environmental conditions. Varied overdrive voltages provide adaptable display responses with proportional power consumption so that power consumption is reduced where visual images of a display content have reduced need for rapid display response. For example, reduced bandwidth availability that impacts display resolution allows reduced overdrive voltages that scale to visual content resolution.

摘要： A portable information handling system having rotationally coupled housing portions disposes first and second OLED display films in an overlapped configuration having the display films slide relative to each other as the housing portions rotate. Presentation of visual images at one or both of the OLED display films in the overlapped portion is adjusted to blend with the images presented at non-overlapping portions of the OLED display films.
