High efficiency ghost illumination cancelation in emissive and non-emissive display panels
Abstract:
Display elements, each having anode and cathode terminals, are arranged into rows and columns. Each row has an anode-line coupled to the anode terminals for its display elements. Each column has a cathode-line coupled to the cathode terminals for its display elements. A switch for each anode-line selectively couples that anode-line to a storage capacitor, and a switch for each cathode-line selectively couples that cathode-line to the storage capacitor. A display driver activates the row driver for a given row and the column driver for a given column. A switch driver closes the switch for the cathode-line for the given column, then opens the switch for that cathode-line. The display driver deactivates the row driver for the given row, after closing the switch for the cathode-line for the given column. The switch driver closes the switch for the anode-line for the given row.
