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: Systems and methods for synchronizing a video source and display circuitry using a dynamic tearing effect (TE) signal are provided. In one embodiment, an electronic display device includes: variable refresh rate circuitry that, when no new frame data is provided to the electronic display device, extends a vertical blanking period and reduces a refresh rate of the electronic display device. A tearing effect signal is generated, which is selectively set to a first logical level at a first period of time and a second logical level at a second period of time. The tearing effect signal is provided to the host electronic device that provides frame data to the electronic display device and upon receipt of new frame data, an un-extended vertical blanking period is returned to and the frame data at the next frame boundary is displayed.

Abstract: This application relates to systems, methods, and apparatus for transitioning a display device between operating modes using a single dedicated pin of a circuit connected to the display device. The dedicated pin can receive a packet signal corresponding to an operating mode for the display device, and the circuit can thereafter cause the display device to transition into the desired operating mode in response to receiving the packet signal. The operating mode can be a low power on mode where an interface connected to the circuit is deactivated and at least some circuitry of the display device is throttled or powered off. The display device can be driven in an all black state while in the low power on mode, thereby allowing the display device to more quickly transition out of the low power on mode compared to when the display device is completely off.
