Abstract: 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.
