CHOLESTERIC LIQUID CRYSTAL WRITING TABLET ERASED BY A PIEZOELECTRIC TRANSDUCER |
摘要 |
A display device includes a cholesteric liquid crystal writing tablet and a piezoelectric transducer. The piezoelectric transducer is subjected to a mechanical force that generates a voltage that is applied to the writing tablet that erases writing on the writing tablet or a portion thereof. A further feature is a display device comprising a cholesteric liquid crystal display and a piezoelectric transducer. The piezoelectric transducer is subjected to a mechanical force that generates a voltage that is applied to the display that places the display or a portion thereof in at least one of a color reflective planar state, a substantially transparent focal conic state and a gray scale state. Also featured is a method of erasing a cholesteric liquid crystal writing tablet. |
