A driving method of a display panel having a resetting step, an addressing step, and a sustaining step in each display cell. The resistive capacitor couples a resistor in series with the capacitor where the resistor provides high resistance without substantially increasing inductance to thereby dampen anti-resonance noise typically generated when multiple decoupling capacitors are used for filtering a broader range of possible noise signal frequencies. The insulation sheet is provided with a via hole and attached on one side of the metal tab. A tip is in contact with the reservoir and one end of the tip acts as a wick to draw the solution from the reservoir to the tip, and the other end of the tip is configured to apply the solution to a surface when that end of the tip is placed in contact with the surface.
