Abstract

This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for driving electromechanical display devices that suffer from adhesion forces. In one aspect, a method for driving a display element is provided that includes applying a first series of voltages to a first electrode and applying a second series of voltages from a set of voltage levels to a second electrode to selectively place a movable layer into an actuated state or un-actuated state based on a voltage difference between the first and second electrodes. The method further includes applying a third series of voltages levels from the set of voltage levels to a third electrode. The third series of voltage levels are applied to the third electrode such that a non-zero voltage exists between the third and second electrodes during a release time period where a desired state is the un-actuated state.
