    Abstract: An electronic device may include a first display pipeline that may output image data via an output path. The electronic device may include first frame merge circuitry coupled to the output path. The electronic device may also include a first multiplexer coupled to the first frame merge circuitry and to the output path. The first multiplexer may transmit the image data from the output path to an electronic display, and, in response to a first control signal associated with the first frame merge circuitry generating a merged output, the first multiplexer transmits the merged output to the electronic display.

    Abstract: An electronic device (10) may include a display (12) panel and an image data source (38) designed to determine a differing region (84) in an image frame by comparing source image data (78) and image data corresponding with a previous image frame (72). The electronic device (10) may also include a display pipeline (36) between the image data source (38) and the display (12) panel. The display pipeline (36) may include image processing circuitry (27) to convert image data from a source space to a display space and image processing circuitry to spatially process the image data. The display pipeline (36) may determine a crop region (116) by converting the differing region (84) to the display space and determine a partial frame region (120), based on the image data to be spatially processed, by the image processing circuitry (27). The display pipeline (36) may also determine and retrieve a fetch region (86) smaller than the image frame by converting the partial frame region to the source space.

    Abstract: A method may include receiving, via a processor, a frame of image data, such that the frame of image data may include an active portion and an idle portion. The active portion may include data for presenting one or more images via a first display of a first electronic device. The method may also include receiving a signal from a second electronic device during the idle portion of the frame of image data, such that the second electronic device is separate from the first display. The method may then involve initiating processing of the frame of image data in response to the signal being received from the second electronic device.

    Abstract: An electronic display device has a panel (16) that operates in conjunction with a light-emitting diode (LED) backlight. The device "slopes" or gradually ramps a change in brightness of an LED (18) based on a target brightness value (84) of the LED (18), a current brightness value of the LED (18), and temperature (88) at the LED (18). The device also may limit power to the backlight (17) based on an estimated power consumption (120) of a current row of LEDs (18) of the backlight (17) and power consumption of the other rows of LEDs (18). The device also may determine a reduced voltage (154) to supply to an LED (18) based on a current (210) to supply to the LED (18) to cause the LED (18) to operate. The device also may send an interrupt (180) to the backlight (17) to block updates to the backlight (17) while image content is written to pixels of the panel (16). The device further compensates for aging of and temperature (88) at an LED (18).
