  • Patent number: 11961485
    Abstract: The present invention relates to a cholesteric liquid crystal display, a liquid crystal driving unit, and a driving method for reducing the maximum driving voltage. The cholesteric liquid crystal display comprises a cholesteric liquid crystal display panel, a temperature detecting device, and a liquid crystal driving unit. If the temperature detecting device detects a temperature below the optimal range for the cholesteric liquid crystal display panel, the liquid crystal driving unit will operate the cholesteric liquid crystal display panel in DDS timing mode. When the temperature detecting device detects that the temperature of the display panel exceeds the optimal temperature range, the liquid crystal driving unit will operate the display panel in PWM timing mode, which can solve the problem of increased power consumption caused by changes in ambient temperature, and can greatly improve the better color level.
