11. A driving method for a cholesteric liquid crystal display which comprises a display panel for displaying an image, where the image is produced by one imaging driving pixel and several non-imaging driving pixels, the driving method comprises the following steps:
applying a first driving voltage with a quantity of first pulse waves to a non-imaging driving pixel within a unit time, and applying a second driving voltage with a quantity of second pulse waves to an imaging driving pixel within the same unit time to drive the display panel, wherein the quantity of the first pulse waves exceeds the quantity of the second pulse waves; and
displaying the image by the display panel.
