Abstract: Embodiments provide for a method of generating and displaying data on a display device, the method comprising receiving an input to interact with an image presented via the display; generating a sequence of frames having an animation frame rate independent of a current refresh rate of the display device; presenting configuration data to the display engine at a display time based on the requested presentation time; and dynamically refreshing the display device based on the display time to display the sequence of frames.

Abstract: Systems, apparatuses, and methods for adjusting the frame refresh rate used for driving frames to a display. A display pipeline is configured to drive a display using a reduced frame refresh rate in certain scenarios. The reduced frame refresh rate may be specified in frame packets which contain configuration data for processing corresponding frames. The display pipeline may drive idle frames to the display to generate the reduced frame refresh rate. When a touch event is detected, the display pipeline may override the reduced frame refresh rate and instead utilize a standard frame refresh rate until all of the frames corresponding to stored frame packets have been processed.

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, apparatuses, and methods for preventing charge accumulation on a display panel of a display. A display pipeline is configured to drive a display using a variable frame refresh rate. The display may also be driven by a polarity inversion cadence to alternate the polarity on the display panel on back-to-back frames. In some cases, the frame refresh rate cadence, as specified in frame packets which contain configuration data for processing corresponding frames, can cause a charge accumulation on the display panel if an odd number of frames are displayed at a first frame refresh rate before switching to a second frame refresh rate. Accordingly, in these cases, the display pipeline may override the frame refresh rate setting for a given frame to cause an even number of frames to be displayed at the first frame refresh rate.

Abstract: An electronic device may be provided with a housing such as a metal housing in which a display is mounted. Control circuitry in the electronic device such as a system-on-chip integrated circuit may produce image data. A display driver integrated circuit may receive the image data from the system-on-chip integrated circuit and may display the image data on the display. In the absence of electrostatic discharge, the display driver integrated circuit may operate normally and may generate a heartbeat signal. When disrupted due to electrostatic discharge, the display driver circuitry may cease production of the heartbeat signal. The system-on-chip integrated circuit can implement a watchdog timer. If the watchdog timer times out because the heartbeat signal is not received within a timeout period, the system-on-chip integrated circuit may reset the display.
