Abstract
A portable electronic device includes a display-input apparatus (108) for displaying alternate character sets, in correspondence with a selected mode of operation of the device. The display-input apparatus uses first and second cholesteric display layers (302, 304) to display the different character sets. Each cholesteric display layer displays a different character set when active. When not active, the cholesteric display layer is rendered transparent.
