Abstract
Provided is a bistable driving method for an electrowetting display, comprising: setting a non-selected voltage for one or more writing rows; switching a row voltage of the one or more writing rows from the non-selected voltage to a selected voltage; applying the digital voltage on at least one column of digital electrodes to be written; switching the row voltage of the one or more writing rows from the selected voltage to the non-selected voltage, and decreasing the digital voltage applied to the at least one column to a voltage less than the opening voltage minus the selected voltage; and applying the steps above to next one or more writing rows until an entire display screen is written.
