Patent ID: 7411573

Claim:
A method for reducing the effect of column memory in a video imager, comprising the steps of: activating one of a plurality of row electrodes; selectively applying a video input signal to a plurality of column electrodes; setting at least one of the plurality of column electrodes to a substantially constant voltage prior to activating a subsequent row electrode; wherein said step of setting at least one of the plurality of column electrodes to a substantially constant voltage further comprises the steps of: writing the video input signal to a memory; activating the subsequent row electrode once the plurality of column electrodes are set to the substantially constant voltage; selectively applying the video input signal from the memory to the plurality of column electrodes; and wherein said step of setting at least one of the plurality of column electrodes to a substantially constant voltage further comprises the step of activating a subsequent row electrode associated with a hidden display line such that a substantially constant brightness associated with the substantially constant voltage can be displayed on the hidden display line.
