Abstract
The present invention relates to a cholesteric liquid crystal display device, and a control method. The cholesteric liquid crystal display device includes a cholesteric liquid crystal display module, a solar battery unit, and a control unit. The control unit further includes an ambient energy management module and an energy storage module. The solar battery unit provides electrical energy to the management module. And the ambient energy management module stores electrical energy in the energy storage module. When it is necessary to refresh the images of the cholesteric liquid crystal display module, and the potential difference of the energy storage module reaches the charging cut-off voltage. The energy storage module can discharge the stored electrical energy to provide the electrical energy required by the cholesteric liquid crystal display module to refresh the image.
