摘要:
An appearance-modifying device (10; 30), for modifying the visual appearance of a surface covered thereby, comprising: first (11) and second (12) oppositely arranged optically transparent substrates; a spacer structure (13; 32) spacing apart en the first (11) and second (12) substrates in such a way that a space between the first (11) and second (12) substrates is divided into a plurality of cells (15, 16; 31a-c). The appearance-modifying device further has, in each cell (15, 16; 31a-c), an optically transparent fluid (19) having a plurality of particles (20) dispersed therein, the particles being moveable in the fluid (19) through application of an electric field; and first (17a, 18a; 33) and second (17b, 18b; 32) electrodes arranged to simultaneously, by application of a voltage across the electrodes, control a distribution of the particles (20) within each of a plurality of the cells (15, 16; 31a-c) from a first, dispersed state in which an appearance of the surface covered by the appearance-modifying device is determined by optical properties of the particles (20), to a second state in which the particles (20) are concentrated adjacent to at least one of the first (17a, 18a; 33) and second (17b, 18b; 32) electrodes in such a way that the appearance-modifying device (10; 30) becomes optically transparent.
摘要(中):
一种用于改变由此覆盖的表面的视觉外观的外观修改装置(10; 30),包括:第一(11)和第二(12)相对布置的光学透明基板; 在第一(11)和第二(12)衬底之间间隔开的间隔结构(13; 32),使得第一(11)和第二(12)衬底之间的空间被分成多个单元(15 ,16; 31a-c)。 外观修改装置在每个单元(15,16; 31a-c)中还具有分散在其中的多个颗粒(20)的光学透明流体(19),所述颗粒可在流体(19)中通过 应用电场; 以及通过跨过电极施加电压而同时设置的第一电极(17a,18a; 33)和第二电极(17b,18b; 32)控制在多个电池单元内的颗粒(20)的分布 15,16; 31a-c)从其中由外观修饰装置覆盖的表面的外观由颗粒(20)的光学性质确定的第一分散状态到第二状态,其中颗粒(20) )以使得外观修改装置(10; 30)变得光学透明的方式集中在第一(17a,18a; 33)和第二(17b,18b; 32)电极中的至少一个电极附近。
