    • The invention more particularly relates to a reusable device for writing, displaying and deleting information with an electronic means on a support means comprising bistable liquid crystals. The object of the invention is a reusable device for writing and displaying information, comprising a substrate (1) onto which are successively applied and from the substrate (1): an electricity conducting coating (2); an optical coating (3) that can absorb all or part of the surrounding light; a coating of a transparent substance (4) in which a plurality of bistable liquid crystals (5) are emulsioned; at least one electricity conducting element (7), characterized in that the electricity conducting element (7) is electrically connected to the electricity conducting coating via an electrical voltage generator (8) to form an electric circuit (9), and in that the electricity conducting element (7) is put into contact and can be moved over the surface of the transparent coating (4) in which a plurality of bistable liquid crystals (5) are emulsioned, to produce a modification of the state of light transmission in said transparent coating at the contact, so as to generate the writing and displaying of information, or the deleting of the displayed information. The invention is used in the technical field of writing and displaying with a liquid crystal support screen.
    • 本发明更具体地涉及一种用于在包括双稳态液晶的支撑装置上用电子装置写入,显示和删除信息的可重复使用装置。 本发明的目的是用于写入和显示信息的可重复使用的装置,包括:基板(1),从基板(1)依次施加到基板(1)上;导电涂层(2); 可吸收全部或部分周围光线的光学涂层(3); 其中多个双稳态液晶(5)被乳化的透明物质(4)的涂层; 至少一个导电元件(7),其特征在于,所述导电元件(7)经由电压发生器(8)电连接到所述导电涂层以形成电路(9),并且所述电力 导电元件(7)接触并可以在其中多个双稳态液晶(5)被乳化的透明涂层(4)的表面上移动,以产生所述透明体(5)中光透射状态的变化 在接触处涂覆,以产生信息的写入和显示,或者删除所显示的信息。 本发明用于具有液晶支撑屏幕的写入和显示技术领域。
