Abstract
A remote display for use with a portable electronic communications device such as a cell phone is disclosed to provide information on a larger remote reflective cholesteric display. The portable communications device may connect with the remote display by wire or wirelessly. The remote display is separate from the portable communications device but can interact with it. Moreover, the remote display may serve multiple purposes, such as providing a user interface, displaying images, and collecting solar power whereby a photovoltaic material behind the display generates electrical energy from light incident on the cholesteric liquid crystal material.
