  • Publication number: 20030071958
    Abstract: A liquid crystal device for writing, inputting, and displaying information comprises: a first substrate, a second substrate, and a cell structure sandwiched between the two substrates, defining a plurality of isolated subcells. Means for applying an electric field to drive states of the cholesteric liquid crystal in the subcells is coupled to the electrodes. An electromagnetic sensitive panel is positioned proximately under the surface of the second substrate for receiving an electronic/magnetic signal transmitted by a writing tool. In use, when the tip of the writing tool is forced again and moved around the surface of the first substrate, a true track of the movement of the tip is directly shown on the writing surface, while information of the movement of the tip of the writing tool is sensed by the electromagnetic sensitive panel simultaneously.
