Abstract
The present invention is a cholesterol liquid crystal display and driving method thereof. The cholesterol liquid crystal display includes a display panel and a liquid crystal driving unit. The display panel is used to display images composed of a row of imaging drive pixels and multiple rows of non-imaging drive pixels. The liquid crystal driving unit simultaneously drives the display panel to show images by applying a first driving voltage to multiple non-imaging drive pixels and a second driving voltage to imaging drive pixels. The first driving voltage has a quantity of the first pulse waves within a unit time, and the second driving voltage has a quantity of the second pulse waves within the unit time. The quantity of the first pulse waves is at least 5 times greater than the quantity of the second pulse waves, and the higher the multiple, the better the display effect.
