    Abstract: A communication device ( 100 ) comprising a body portion ( 110 ) and a display portion ( 130 ) that is rotatably connected to the body portion. A switch ( 160,161, 162, 163,164 ) is operable to reverse the modes of the inner ( 141 ) and outer ( 142 ) bistable clear-reflective layers in response to rotation of the display portion ( 130 ) with respect to the body portion ( 110 ).

    Abstract: Rewritable signs ( 100, 1300 ) that include bistable cholesteric liquid crystal layers ( 102, 1402, 1404, 1406 ) are provided. According to one embodiment a rewritable sign ( 100 ) is devoid of circuitry for establishing electric fields in localize regions for writing information to the rewritable sign ( 100 ), and is consequently inexpensive. In the latter embodiment, a separate information writer ( 400 ) that includes an array of pixel electrodes ( 404 ) that is driven by an active matrix ( 602 ) is used to write information on the rewritable sign. According to another embodiment a rewritable sign ( 1300 ) includes three cholesteric liquid layers ( 1402, 1404, 1406 ) each of which reflects a different primary color. The three cholesteric liquid crystal layers ( 1402, 1404, 1406 ) are interleaved with sets of conductive lines ( 1316, 1320, 1322, 1324 ) that are used to apply signals to the cholesteric liquid crystal layers ( 1402, 1404, 1406 ) for the purpose of writing information.

    Abstract translation: 提供了包括双稳态胆甾型液晶层（102,1402,1404,1406）的可重写符号（100,1300）。 根据一个实施例，可重写符号（100）没有用于在用于将信息写入可重写符号（100）的本地化区域中建立电场的电路，因此便宜。 在后一实施例中，包括由有源矩阵（602）驱动的像素电极阵列（404）的单独信息写入器（400）用于写入关于可重写符号的信息。 根据另一个实施例，可重写标志（1300）包括三个胆固醇液体层（1402,1404,1406），每个胆固醇液体层反映不同的原色。 三个胆甾型液晶层（1402,1404,1406）与用于将信号施加到胆甾醇型液晶层（1402,1404,1406）的导线组（1316,1320,1322,1324）交错，用于 写信息的目的。
