In an embodiment, an electronic display may include an electronic display panel that includes a plurality of display pixels configured to emit light; a first pre-charge voltage source; and a second pre-charge voltage source; and a microdriver that may include: a capacitor coupled at a first terminal to the first pre-charge voltage source and coupled at a second terminal to the second pre-charge voltage source; and a buffer. The buffer may include a positive input terminal coupled to the first pre-charge voltage source and the capacitor; an output terminal coupled to a plurality of driving circuits; and a negative input terminal coupled to the output terminal.

Systems and methods for IR-independent pre-charge and inverter- based IR reduction

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.
