A color shift compensation method, a color shift compensation system and a display panel are provided. The color shift compensation method includes: accumulating actual display time of a display panel; determining whether or not the actual display time reaches a preset cumulative display time threshold; and in a case where the actual display time reaches the preset cumulative display time threshold, driving the display panel to display according to compensated adjustment voltages that are pre-stored, and in a case where the actual display time does not reach the preset cumulative display time threshold, driving the display panel to display according to current adjustment voltages that are pre-stored.

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 method of displaying an image by using a display device. The method includes: grouping pixels included in a display unit into pixel blocks, generating a first accumulated stress map representing a degree of a deteriorated performance of the pixels included in the pixel blocks based on first image data of a current frame image, and determining a shiftable range of the current frame image by analyzing the first accumulated stress map. The first image data is corrected to second image data in which the current frame image is shifted within the shiftable range.

A degradation compensator including a compensation factor determiner configured to determine a compensation factor based on a distance between adjacent sub-pixels, and a data compensator configured to apply the compensation factor to a stress compensation weight to generate compensation data for compensating image data.

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.

There are provided display controllers and driving methods related to those described in US Published Patent Application No. 2013/0194250. These include (a) a display controller having an update buffer, means for removing from the update buffer pixels not requiring updating, and means to ensure that pixels having certain special states are not removed from the update buffer; (b) a method of driving a bistable display wherein, in a pixel undergoing a white-to-white transition and lying adjacent another pixel undergoing a visible transition, there is applied to the pixel one or more balanced pulse pairs and at least one top-off pulse; (c) a method of driving a bistable display by overlaying a non-rectangular item over a pre-existing image content and then removing the item, where only pixels in the region of the item perform transitions (including self-transitions); and (d) a method of driving a bistable display in which a proportion of background pixels not undergoing an optical change are subjected to a refresh pulse to correct optical state drift.

A display system includes a first memory and a display driver. The display system is configured to control the first memory to receive compensation information from the first memory with a first frequency and generate data signals for image data to be displayed on a display panel. The generation of the data signals comprises performing a compensation for the data signals based on the compensation information received from the first memory. The display driver is further configured to update pixels of the display panel with the data signals during an active display state. The display driver is further configured to generate updated compensation information based at least in part on the image data and the compensation information received from the first memory and transmit the updated compensation information to the first memory during the active display state with a second frequency lower than the first frequency.

Systems and methods are disclosed herein for monitoring light emissions in electronic devices. The disclosed techniques herein provide for determining a display duration of display devices for a user. Light emission profiles for each of the display devices are determined. A cumulative emissions exposure is determined that is based on the light emission profiles for the display devices and the display duration of the display devices for the user. A determination is made whether the cumulative emissions exposure exceeds a light emission exposure limit set for the user. In a positive determination, an instruction is transmitted to the display devices for execution of a remedial action based on predefined rules.

A driving controller includes: a logo determiner configured to determine whether or not input image data includes a logo; a logo grayscale value calculator configured to calculate a logo grayscale value of a logo area corresponding to the logo in response to the input image data including the logo; a light emitting element life expectancy determiner configured to determine a life expectancy of a light emitting element corresponding to the logo area; a compensation reference grayscale value generator configured to determine a compensation reference grayscale value according to the life expectancy of the light emitting element corresponding to the logo area; and a logo luminance compensator configured to compare the logo grayscale value to the compensation reference grayscale value to determine whether or not to compensate a luminance of the logo area.

In one embodiment, a method for managing a display of an information handling system includes: monitoring, by a display controller, a usage period of the display indicating a period of time in which the display is in an illuminated state; determining, by the display controller, that the usage period is greater than a threshold usage period; causing, by the display controller, a brightness level of the display to decrease; sending, by the display controller, a signal to a graphics processing unit; receiving, by the graphics processing unit, the signal; determining, by the graphics processing unit, a contrast level associated with one or more images presented to a user; determining, by the graphics processing unit, a gamma level associated with the one or more images; and processing, by the graphics processing unit, the one or more images based on the contrast level and the gamma level.
