Claim 4:
5. A cholesteric liquid crystal driving unit with multiple timing modes and an optimal temperature range, for reducing maximum optimal driving voltage of a cholesteric liquid crystal display which comprises a cholesteric liquid crystal display for displaying images and a temperature detecting device for measuring temperature of the cholesteric liquid crystal display panel, the driving unit comprises:
a DDS (Dynamic Driving Scheme) driving module, driving the cholesteric liquid crystal display panel in the DDS timing module if the temperature detecting device detects a temperature of the display panel below the optimal temperature range; and
a PWM (Pulse-Width Modulation) driving module, driving the cholesteric liquid crystal display panel in the PWM timing module if the temperature detecting device measures a temperature on the cholesteric liquid crystal display panel that exceeds the optimal temperature range.
