Claim 8:
9. A control method with multiple timing modes for reducing maximum driving voltage and a first optimal temperature range, a second optimal temperature range, and a third optimal temperature range, a cholesteric liquid crystal display device comprising a cholesteric liquid crystal display panel for displaying image, wherein the second optimal temperature range is between the first and the third optimal temperature ranges and the first, the second, and the third optimal temperature range are not overlapped, the method comprises the steps:
measuring a temperature of the cholesteric liquid crystal display panel;
driving the cholesteric liquid crystal display panel in the DDS (Dynamic Driving Scheme) timing module if the temperature detecting device detects the temperature of the display panel in the range of the second optimal temperature range;
driving the cholesteric liquid crystal display panel in the PWM (Pulse-Width Modulation) timing module if the temperature detecting device measures the temperature on the cholesteric liquid crystal display panel that exceeds the first optimal temperature range or is in the range of the third optimal temperature range.
