Electronic displays and electronic devices including such electronic displays and antennas are provided for improved transmission of signals through circuitry of the electronic display. The electronic display may include multiple power supply tiles that are separated with non-conductive gaps to reduce circulation of eddy currents induced by the transmission signals. Moreover, voltage supply routing paths within the power supply tiles may be grouped to provide non-conductive gaps within the power supply tiles. Accordingly, the antenna may provide the transmission signals through the electronic display with improved efficiency based on reducing surface currents (e.g., eddy currents) on the electronic display.

Display and antenna co-design to reduce antenna transmission loss

In some examples, a touch screen can include touch electrodes that can function as drive (Tx) electrodes and sense (Rx) electrodes during a touch sensing operation of the electronic device. The drive electrodes can include +Tx electrodes and −Tx electrodes that can receive drive signals that can have the same amplitude and frequency and opposite phases, for example. In some examples, the surface areas of the +Tx electrodes and the −Tx electrodes can be the same and the distances of the +Tx electrodes and −Tx electrodes from the Rx electrodes can be different. In some examples, the total charge coupled to a proximate or touching object can be zero, which can mitigate problems associated with ungrounded or poorly grounded objects in contact with the touch screen.
