Abstract: An electronic device may include a display panel. When content of an image frame is expected to consume relatively higher amounts of power, a controller of the electronic device may operate a switch to change a power supply of the display panel to be a power management integrated circuit of the electronic device. However, when content of an image frame is expected to consume relatively less amounts of power, the controller may operate the switch to change the power supply of the display panel to be a power supply of an electronic display, such as a power supply used to power driver circuitry of the electronic display.

Abstract: A user interface unit in a graphics processing display pipe may include registers programmable with information that defines active regions of an image frame. Pixels within the active regions of the image frame are meant to be displayed, while pixels outside of the active regions of the image frame are not to be displayed. Fetch circuitry within the user interface unit may fetch frames from memory, fetching only the pixels within the active regions of the image frames as defined by the programmed contents of the registers. The user interface unit may then provide the fetched pixels to a blend unit to blend the fetched pixels with pixels from other frames or pixels of a video stream to produce output frames. When blended with pixels of a video stream, the fetched pixels may be displayed as a graphics overlay on top of the video stream.

Abstract: A scaling unit is disclosed that is within a computing device having an internal display and an external interface. The scaling unit facilitates the concurrent presentation of images on the internal display and an external display connected to the external interface. In configurations in which the external interface does not have sufficient data width to concurrently display images on the external display at the same resolution as the internal display, the scaling unit may be used to reduce the number of pixels in a line, thus reducing bandwidth requirements at the external interface. The scaling unit may also scale further to maintain an aspect ratio of the image displayed on the internal display. Further vertical scaling may be performed outside the computing device (e.g., by a dongle coupled between the computing device and the external display), such that the scaling unit may be implemented with reduced memory requirements.
