Abstract
A cholesterol liquid crystal display device includes a liquid crystal display panel and a liquid crystal driving unit. The liquid crystal display panel has a plurality of pixels. The liquid crystal driving unit applies row driving voltages and column driving voltages to a designated pixel according to the input signal. After the input signal is transmitted, the liquid crystal driving unit activates the power-down signal within a certain period of time to reduce the row driving voltage and the column driving voltage applied to the specified pixel. Thereby, the crosstalk phenomenon on the cholesteric liquid crystal display device can be improved.
