End users subscribe to use information handling systems having a selected of available performance characteristics defined by a display configuration selected to build the information handling systems. A manufacturer meets subscriptions with information handling systems built from an inventory of new displays, deployed displays of information handling system in use by subscribers, and separated displays taken from returned information handling systems and re-used. End user subscriptions are met in part by building replacement information handling systems with separated displays having a useful life remaining that aligns with end user display usage patterns tracked over time, benchmarked performance metrics and end user subscription performance characteristics.

A display device includes a display panel including a panel region. The panel region includes a block, and the block includes a pixel. The display device further includes a temperature sensor sensing a region temperature of the panel region and a temperature estimator estimating a temperature of the display panel. The temperature estimator includes a stress calculator calculating an accumulated stress value corresponding to the block based on input image data, a temperature potential calculator calculating a temperature potential corresponding to the block based on the accumulated stress value and a resistance model related to a heat diffusion within the display panel, and a temperature calculator calculating a block temperature based on the region temperature and the temperature potential. The temperature of the display panel is estimated based on the block temperature.

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.

An electronic device is provided. The electronic device includes a display including a plurality of display pixels, a memory, and at least one processor, wherein the at least one processor may be configured to drive the display by variably adjusting a first display region and a second display region in which visual information is to be displayed on the display, based on an operation state or a display structure state of the electronic device, calculate a difference in usage of the display between the first display region and the second display region, variably determine a size of a boundary compensation region between the first display region and the second display region, based on the difference in usage, and compensate for an image of the boundary compensation region.

A display device includes a display panel, a first memory, and a degradation compensator. The first memory device stores stress data including degradation values representing a degradation degree of each of the blocks in the display panel. The degradation compensator loads the stress data from the first memory device, updates the stress data based on current input data and a maximum degradation value, updates the maximum degradation value based on degradation values included in the updated stress data, and generate compensated data by compensating for the current input data based on the updated stress data. The degradation compensator determines whether a first degradation value included in the stress data is normal by comparing the first degradation value with the maximum degradation value, and updates the first degradation value based on at least one adjacent degradation value adjacent to the first degradation value, when the first degradation value is abnormal.

In a display element such as an organic EL element, deterioration progresses due to light emission, and emission luminance is lowered even if the same voltage is applied to the display element. Therefore, use over time causes variations in luminance of each pixel, thereby a so-called “image burn-in” phenomenon occurs. Given this factor, the invention provides a display device which can reduce the difference in deterioration of a display element in each pixel and suppress variations in light emission of a display element in a pixel. It is prevented that only a specific pixel has a long accumulated lighting time. For that purpose, a gray scale of a display pattern is changed to prevent the difference in deterioration of display element in pixels from increasing. Alternatively, a specific display pattern is prevented from being fixedly displayed in a specific region. Further alternatively, a pixel lagging behind in deterioration is deteriorated so that the accumulated lighting time of pixels is equal to each other.

An image sticking compensation device includes: a deterioration calculator which calculates deterioration data of a current frame based on input image data and sensing frequency information which are received from a timing controller; an accumulator which accumulates the deterioration data and generates age data in which the deterioration data is accumulated; and a compensator which determines a grayscale compensation value corresponding to the age data and an input grayscale value of the input image data, and outputs age compensation data by applying the grayscale compensation value to the input image data. The sensing frequency information includes a frequency of the current frame, and the deterioration data varies in accordance with the frequency of the current frame.

A display device includes a display panel which displays an image, an image sticking compensator which receives image data, compensates for the image data based on lifespan data to generate lifespan compensation data, and a panel driver which provides data signals corresponding to the lifespan compensation data to the display panel. The image sticking compensator includes a compensator which receives the first cumulative data, generates the lifespan data based on the first cumulative data, compensates for the image data based on the lifespan data to generate the lifespan compensation data, a memory controller which receives the second cumulative data and the lifespan data from the compensator, a volatile memory which stores the second cumulative data from the memory controller, a main nonvolatile memory which stores the second cumulative data from the memory controller, and a sub-nonvolatile memory which stores the lifespan data from the memory controller.

An electronic display pipeline may process image data for display on an electronic display. The electronic display pipeline may include burn-in compensation statistics collection circuitry and burn-in compensation circuitry. The burn-in compensation statistics collection circuitry may collect image statistics based at least in part on the image data. The statistics may estimate a likely amount of non-uniform aging of the sub-pixels of the electronic display. The burn-in compensation circuitry may apply a gain to sub-pixels of the image data to account for non-uniform aging of corresponding sub-pixels of the electronic display. The applied gain may be based at least in part on the image statistics collected by the burn-in compensation statistics collection circuitry.

Embodiments of the disclosed subject matter provide a device that includes a full color display. A camera may be disposed below the full color display. A controller may modify a video signal applied to one or more sub-pixels of the full color display based on a predicted degradation of the one or more sub-pixels, such that the modification is updated by the controller based on luminance data for the one or more subpixels acquired by the camera.
