Abstract: An electronic device such as a head-mounted device may have displays. The display may have regions of lower (L) and higher (M, H) resolution to reduce data bandwidth and power consumption for the display while preserving satisfactory image quality. Data lines may be shared by lower and higher resolution portions of a display or different portions of a display with different resolutions may be supplied with different numbers of data lines. Data line length may be varied in transition regions between lower resolution and higher resolution portions of a display to reduce visible discontinuities between the lower and higher resolution portions. The lower and higher resolution portions of the display may be dynamically adjusted using dynamically adjustable gate driver circuitry and dynamically adjustable data line driver circuitry.

Abstract: This application relates to systems, methods, and apparatus for optimizing the operations of a power converter of a display panel based on image data to be output by the display panel. The power converter can include one or more switches that can be activated or deactivated based on the image data in order to shift a power efficiency of the power converter. Power efficiency is shifted as a result of balancing an amount of charge necessary for a load with an amount of resistance created when activating switches of the power converter. Therefore, by dynamically altering a configuration of a power converter based on image data, power efficiency of the power converter can be improved.

Abstract: Systems and methods are provided for adjusting and displaying image data to account for variable common voltage error across separate common electrode sub-plates. The image data may be adjusted based on a common mode common voltage error on a common voltage line coupled to more than one different common electrode sub-plate. Each common electrode sub-plate may carry a common voltage that varies depending on values of the image data programmed to pixels associated with that common electrode sub-plate.

Abstract: A touch screen is disclosed. A plurality of common electrodes can be configured to operate as display circuitry during a display phase, and to operate as touch sensing circuitry during a touch sensing phase. The plurality of common electrodes can include a first common electrode associated with a first display pixel, and a second common electrode associated with a second display pixel. Circuitry can be configured to update the first display pixel at a first time while driving the first common electrode but not the second common electrode, and update the second display pixel at a second time, after the first time, while driving the second common electrode but not the first common electrode. In some examples, the circuitry can be configured to leave the second common electrode floating while driving the first common electrode, and leave the first common electrode floating while driving the second common electrode.
