Abstract: An electronic device may include a display panel to display an image and a display pipeline to process image data for the image. The display pipeline may include a controller to determine a first potential presentation time based on a maximum refresh rate of the display panel. The controller may also determine if a second target presentation time of a second image is equal to the first potential presentation time before a pipeline configuration time, and if the second target presentation time of the second image is equal to a second potential presentation time that occurs after the first potential presentation time and before a first pre-notification time occurring before the pipeline configuration time. The controller may output a first pre-notification signal at the first pre-notification time that instructs the display panel to pause self-refreshes until after the second image is displayed.

Abstract: A data processing system can store a long-term history of pixel luminance values in a secure memory and use those values to create burn-in compensation values that are used to mitigate burn-in effect on a display. The long-term history can be updated over time with new, accumulated pixel luminance values.

Abstract: In situations with reduced image changes, display panels, such as the ones disclosed herein, may reduce their power consumption by performing self-refresh cycles, in which they may display locally stored data in the display panel instead of retrieving it from an image buffer. Methods and circuitry for management of the self-refresh cycle may reduce jitter, luminance errors, and/or flickers that may be caused by untimely self-refresh cycles that may occur as a result of latency in the image buffer. In some implementations, the display panel may have a dedicated low latency input that notifies an arrival of an incoming image. In some implementations, the self-refresh cycles of the panel may be managed by a host or a buffer that is responsible for sending the images.

Abstract: Circuits, methods, and apparatus that may estimate the power being consumed by an OLED display screen of an electronic device, may provide further information about that power usage, may modify or change functions performed by the electronic device based on that power usage, and may inform an application's developer about the amount of power being used by the electronic device while the electronic device is running the application. One example may estimate the power being used by an OLED display screen of an electronic device by determining the content of images being displayed during a duration. The estimated power may then be presented to a user. The estimated power may be used in decisions to modify or change parameters of the screen or other device components.

Abstract: An embodiment of a system may include a plurality of media units, a processor, and circuitry. Each media unit may be configured to execute one or more commands to process a display image. The processor may be configured to store a plurality of media processing commands in a queue. The circuitry may be configured to retrieve a first media processing command from the queue and send the first media processing command to a first media unit. The circuitry may also be configured to retrieve a second media processing from the queue and send the second media processing command to a second media unit in response to receiving an interrupt from the first media unit. The circuitry may then copy data from the first media unit to the second media unit in response to receiving the interrupt from the first media unit.

Abstract: Systems, methods, and non-transitory media are presented that provide for improving color accuracy. An electronic display includes a display region having multiple pixels each having multiple subpixels. The electronic device also includes a display pipeline coupled to the electronic display. The display pipeline is configured to receive image data and perform white point compensation on the image data to compensate for a current drop in the display to cause the display to display a target white point when displaying white. The display pipeline also is configured to correct white point overcompensation on the image data to reduce possible oversaturation of non-white pixels using the white point compensation. Finally, the display pipeline is configured to output the compensated and corrected image data to the electronic display to facilitate displaying the compensated and corrected image data on the display region.
