High efficiency ghost illumination cancelation in emissive and non-emissive display panels
Disclosed herein is a method of operating a display panel having a matrix of display elements. The method includes ordered steps of: (1) causing flow of current from a source of power, into an anode of a given display element, out of a cathode of the given display element to ground, wherein the flow of current into the anode and out the cathode to ground results in charging of a parasitic capacitance associated with the anode, (2) transferring charge from a storage capacitor to a parasitic capacitance associated with the cathode, and (3) stopping the flow of current, and then transferring charge from the parasitic capacitance associated with the anode to the storage capacitor.
