1. A cholesteric liquid crystal display device, comprising:
a cholesteric liquid crystal display unit, comprising a light-incident surface for receiving external light;
a solar battery unit, comprising a light-receiving surface attached to a surface of the cholesteric liquid crystal display unit, and positioned away from the light-incident surface, wherein the light-receiving surface is used to convert a portion of the external light into electrical energy; and
a control unit, comprising an ambient energy management module electrically connected to the solar battery unit, an energy storage module electrically connected to both the ambient energy management module and the cholesteric liquid crystal display unit, a main control module electrically connected to the ambient energy management module, and a timing control module electrically connected to the main control module and the cholesteric liquid crystal display unit, wherein the solar battery unit stores the electrical energy through the ambient energy management module for supplying the cholesteric liquid crystal display unit.
