Abstract
A cholesteric liquid crystal display device with efficient charging capability and its charging method are provided. The cholesteric liquid crystal display device comprises a cholesteric liquid crystal display unit, a power unit, and a control unit. The power unit comprising a solar cell module and an energy storage module electrically connected to the solar cell module. When the control unit detects the electrical energy stored in the energy storage module is less than a threshold, the control unit drives the cholesteric liquid crystal display unit to display in the FC state, then allowing the solar cell module to charge. When the control unit detects that the electrical energy stored in the energy storage module is greater than the threshold, the control unit drives the cholesteric liquid crystal display unit to display in the PL state, thereby reduces any afterimages issues that may occur during image transitions of the display device.
