Abstract

A charge injection circuit for use in display system of an electronic device can include an injection capacitance and circuitry that receives an input signal corresponding to drive signals from a display driver of the display system; and generates an inverted output signal corresponding to the drive signals for delivery to a power input of a display panel of the display system via the injection capacitance, thereby mitigating transient disruption of one or more power rails of the display panel associated with parasitic capacitive coupling of the drive signals to the one or more power rails of the display panel. The injection capacitance can be a capacitor having a capacitance value corresponding to a total parasitic capacitance capacitively coupling data lines to the one or more power rails within the display panel.
