Abstract: A system includes processing circuitry configured to determine a plurality of line-specific common voltage (Vcom) values for a plurality of common electrodes of an electronic display. Each of the plurality of line-specific Vcom values is associated with a line of pixels of a plurality of lines of pixels of the electronic display. Additionally, the processing circuitry is configured to cause the plurality of line-specific Vcom values to be provided to the plurality of lines of pixels.

Abstract: The present disclosure relates generally to electronic devices, and more particularly, to electronic devices that utilize electromagnetic signals (e.g., radio frequency (RF) signals), transmitters, and receivers in various processes, such as cellular and wireless device processes in a at least partially metal enclosure. The present disclosure describes devices that may be used to wirelessly transmit and/or receive electromagnetic signals between processing components and sensing components, for example, by improving sensing device design and thus forming an integrated sensing tag that leverages passive RF technology, such as radio frequency identification (RFID) tags.
