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.

An information handling system includes a display device and a processor. The display device outputs pixels associated with a text font. The processor converts red, green, blue (RGB) pixels to image perspective transformation (IPT) pixels. The processor further sharpens one or more of the IPT pixels that do not have color. The sharpening of the one or more of the IPT pixels identifies edges of the text font and defines widths of the text font. The processor corrects edge overshoot and edge undershoot created by a digital filter. The edge overshoot and the edge undershoot are corrected for each IPT pixel associated with the text edges. The processor also reduces noise enhancement in the sharpened IPT pixels, retains grey text portions of each of the sharpened IPT pixels, and converts the IPT pixels to new RGB pixels. The processor outputs the new RGB pixels to the display device.

Text sharpening for legibility enhancement or display power savings

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.

Display assembly apparatus and methods for information handling systems

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.

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.

Methods and a system for pixel-by-pixel correction of diffuse reflected and specular reflected light on a display device of an information handling system. Voltage values of pixels of the display device are measured by sensors. Measured voltage values of a pixel are converted to a digital value. A digital correction value calculated based on whether diffuse reflected light or diffuse reflected light and specular reflected light is found on the pixel. A sigmoid transfer function and discrete sharpening filter is performed on the pixel, if the digital correction value is less than zero.

End user cumulative blue light exposure from a display is tracked over time so that a message may be provided to the end user if the exposure exceeds a threshold. For instance, a display frame buffer is retrieved to determine an average blue light component presented at the display, which is then adjusted based upon display characteristics, such as display size, luminance and brightness, end user distance to the display and a sensed ambient blue light component.

Methods for manufacturing a multilayer composite display cover include stacking a plurality of composite layers, each comprising an ultra-thin glass sheet covered in a polymer layer. After a cover glass sheet is placed on an exposed polymer layer, the composite layers may be bonded together. A ceramic coating may be applied to the external surfaces to increase hardness.

A method includes determining a first brightness level of a first video frame and a second brightness level of a second video frame, the second video frame immediately following the first video frame. In response to determining that the second brightness level differs from the first brightness level by at least a predetermined amount, the method includes modifying the brightness of the second video frame and a predetermined number of successive frames to provide successive fractional increments of brightness between the first brightness level and the second brightness level.

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.
