Abstract: Techniques for generating pixel shifting patterns for organic light emitting diode (OLED) displays are provided. Pixel usage data for the OLED display can be accumulated. Areas of the OLED display susceptible to burn-in damage can be identified based on the accumulated pixel usage data. A pixel shifting pattern can be generated based on the accumulated pixel image data and data relating to an image to be displayed. The pixel shifting pattern can be generated to avoid the areas identified as susceptible to burn-in damage. The pixel shifting pattern can be applied to the image to be displayed to generate modified image data. The modified image data can limit further damage to the OLED display and thereby delay the onset of undesirable burn-in effects.

Abstract: Techniques for implementing aging compensation for a display are described. An example of an electronic device includes a display comprising pixels, each pixel comprising one or more Light Emitting Diodes (LEDs). The electronic device also includes a display aging compensation unit to receive input frame data corresponding to content to be displayed, adjust the input frame data to generate output frame data based on a degree of aging of the LEDs, and send the output frame data to the display. The electronic device also includes a display aging monitoring and compensation processing unit to accumulate aging data that describes the degree of aging of the LEDs. The aging data is accumulated by sampling the output frame data at a sampling point in accordance with a sampling configuration, and the aging data collected at the sampling point is applied to other pixels in the vicinity of the sampling point. The display aging monitoring and compensation processing unit determines a degree of compensation to apply to the other pixels based on the aging data collected at the sampling point and an aging difference between the other pixels and the sampling point.

Abstract: Methods and apparatus to implement aging compensation for emissive displays with subpixel rendering are disclosed. An example apparatus includes a converter to convert red-green-blue (RGB) data to subpixel rendering (SPR) data. The RGB data is indicative of an image to be rendered on an emissive display screen. The apparatus includes a compensator to apply pixel correction values to the SPR data to generate corrected SPR data to compensate for pixel degradation. The apparatus further includes a usage accumulator to track pixel usage based on the corrected SPR data. The apparatus also includes a correction calculator to calculate the pixel correction values based on the pixel usage.

Abstract: Techniques for displaying content on an OLED display while decreasing the appearance of image sticking are provided. In an example, a computing system, includes an organic light-emitting diode (OLED) display and a memory to store pixel history values for blocks of pixels in the OLED display. A granularity selector determines a size for the blocks of pixels in the OLED display.

Abstract: An apparatus is described. The apparatus includes a transparent display having pixels that appear transparent when in an off mode, and appear as one or more colors when in an on mode. The apparatus also includes a frame surrounding a perimeter of the transparent display. The frame includes non-transparent components that present images on the transparent display. The apparatus additionally includes a connected member that is connected with the transparent display. The connected member provides a contrast to the transparent display when the connected member is positioned opposite a viewing side of the transparent display.
