Bistable driving method for electrowetting display and related electrowetting display

A bistable driving method for an electrowetting display, comprising:

• S1:
• setting a non-selected voltage for one or more writing lines, the non-selected voltage being less than an opening voltage minus a digital voltage but greater than a closing voltage, wherein the opening voltage is a voltage for opening an oil film existing on an electrode surface, and the closing voltage is a voltage for closing the oil film existing on the electrode surface;
• S2:
• switching a line voltage of the one or more writing lines from the non-selected voltage to a selected voltage, the selected voltage being less than the opening voltage but greater than the opening voltage minus the digital voltage;
• S3:
• applying the digital voltage on at least one column to be written, to enable a voltage on, at least one pixel determined by the one or more writing lines and the at least one column to be written, to be greater than the opening voltage;
• S4:
• switching the line voltage of the one or more writing lines from the selected voltage to the non-selected voltage, and decreasing the digital voltage applied on the at least one column to a voltage less than the opening voltage minus the selected voltage;
• and
• S5:
• applying the steps S1 to S4 to next one or more writing lines until the entire display is written.
