Abstract: Devices and methods for improving image quality and decreasing power consumption of an electronic display are provided. The electronic device includes a display panel including a plurality of pixels configured to display an image, and to operate at multiple refresh rates. The electronic device also includes a processor configured to instruct the display panel to transition between the multiple refresh rates based at least in part on a blur effective width of the image.

Abstract: Devices, storage media, and methods for compensating for aging and temperature variations using dual-loop compensation are provided. The compensating for temperature and aging variations of one or more pixels of the display using a coarse scan loop updated at a faster rate. Compensation also includes compensating for aging variations of the one or more pixels of the display using a fine scan loop updated at a slower rate.

Abstract: Systems, methods, and devices for adjusting image display on an electronic display by predicting a temperature change of the electronic display due to heat-producing components near the display or due to changes in content. An electronic device may include an electronic display and processing circuitry. The electronic display may include pixels with behaviors that vary with temperature. As such, the processing circuitry may generate image data to send to the electronic display and adjust the image data or vary an operation of the electronic display based at least in part on a predicted temperature effect on at least part of the active area of the electronic display. The processing circuitry may determine the predicted temperature effect at least in part due to a first heat producing component or changes in content of the image data.

Abstract: A mobile electronic device includes a display having an active array and a reference array. The active array includes a pixel and the reference array includes a reference pixel. The mobile electronic device also includes processing circuitry communicatively coupled to the display. The processing circuitry is configured to instruct the active array to drive the pixel based at least in part on a current-voltage relationship of the pixel and a reference current-voltage relationship of the reference pixel.
